intercepts in the graph of g(x) = x2 +2. Be sure to include the transformations that occurred between the parent functio
f(x) and its image g(x).

Answers

Answer 1

Answer:

The function f(x) intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.

Step-by-step explanation:

In this question you first form the table for values of x with corresponding values of f(x) that you will use to graph the function f(x)=x².Then do the same for the function g(x)=x²+2.Take a point from the parent function f(x) and compare it with its image in the function g(x) to identify the transformation that occurred.Graph the two equations to visually see the x-intercepts in both equations.

In the parent function f(x)=x² form a table as shown below;

x                      f(x)=x²          coordinate to plot

-3                     -3²=9                (-3,9)

-2                      -2²=4                (-2,4)

-1                        -1²=1                 (-1,1)

0                         0²=0               (0,0)

1                           1²=1                 (1,1)

2                          2²=4               (2,4)

3                           3²=9               (3,9)

Use the coordinates to plot the graph of f(x)=x² on a graph tool and see the number of x-intercept values

In the function g(x)=x²+2 also form your table for values of g(x) with corresponding values of x

x                              g(x)=x²+2                                          coordinate to plot

-3                          -3²+2=9+2=11                                          (-3,11)

-2                          -2²+2=4+2=6                                          (-2,6)

-1                           -1²+2=1+2=3                                             (-1,3)

0                            0²+2=2                                                    (0,2)

1                             1²+2=1+2=3                                              (1,3)

2                            2²+2=4+2=6                                             (2,6)

3                            3²+2=9+2=11                                             (3,11)

Use the coordinates to plot the graph of g(x)=x²+2  on a graph tool to determine the number of x intercept values

You can determine the transformation that occurred too, how?

Take a point on the parent function f(x) and compare it with its image in the function g(x)

Let take point (-3,9) and compare it to (-3,11).You notice x coordinate did not change but the y coordinate shifted 2 units upwards along the y-axis.To determine this dilation you subtract the coordinates of object point from that of image point.

[tex]=(\frac{0-0}{11-9}) =(\frac{0}{2} )=(0,2)[/tex]

The dilation was (0,2)

Solution

From the graphs, the function f(x), intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.

Given that AB/DE = BC/EF = 1/2, complete the statements to show that △ABC ~ △DEF by the SAS similarity theorem.

1st box: congruent, parallel, or perpendicular

2nd box: A and D, B and E, or C and F

3rd box: congruent, supplementary, or vertical

Answers

Answer:

1st box ⇒ perpendicular

2nd box ⇒ B and E

3rd box ⇒ congruent

Step-by-step explanation:

* Lets revise the case SAS of similarity

- SAS similarity : In two triangles, if two sets of corresponding sides  

   are proportional and the included angles are equal then the two  

   triangles are similar.

- Example : In triangle ABC and DEF, if m∠A = m∠D and  

  AB/DE = AC/DF then the two triangles are similar by SAS

* Lets solve the problem

- In Δ ABC and Δ DEF

∵ AB/DE = BC/EF = 1/2

- That means two sets of corresponding sides are proportion

∵ AB is a vertical side and BC is a horizontal side

∵ DE is a vertical side and EF is a horizontal side

∵ Horizontal and vertical lines are perpendicular

∴ AB ⊥ BC and DE ⊥ EF

- So angles B and E are right angles by definition of perpendicular

   lines

∵ All right angles are congruent

∴ m∠B = m∠D

∵ The two triangles have two sets of corresponding sides are

  proportion and the included angles are equal then the two

  triangles are similar

∴ △ABC ~ △DEF by the SAS similarity theorem

Answer:

1. Perpendicular

2. B and E

3. Congruent

Step-by-step explanation:

Horizontal and vertical lines are always perpendicular. So, the answer for the first gap is PERPENDICULAR.

Line BC is horizontal line, line AB is vertical line, so lines BC and AB are perpendicular and, therefore, angle B is right angle. Line EF is horizontal line, line ED is vertical line, so lines EF and ED are perpendicular and, therefore, angle E is right angle. So, answer for the second option is angles B and E.

Every two right angles are congruent.

Having two pairs of proportional sides and a pair of congruent adjacent angles, you can apply SAS similarity Postulate.

After a gas-filled balloon is released, it rises 90 feet by the end of the first minute. By the end of the second minute, the balloon rises 120 feet, and by the end of the third minute, it rises 150 feet. How many feet would the balloon rise in 8 minutes?

Answers

Answer: 300 feet

Step-by-step explanation:

Note that:

[tex]120-90 = 30[/tex]

[tex]150-120 = 30[/tex].

Then the balloon rises at a constant rate of 30 meters per minute.

We can represent this situation through an arithmetic sequence as shown below

[tex]a_n =a_1 + d(n-1)[/tex]

Where [tex]a_1=90[/tex] is the first term of the sequence and [tex]a_n[/tex] is the n-th term of the sequence and [tex]d=30[/tex] is the common difference between two consecutive terms.

In this case we look for the height of the balloon after 8 minutes.

Then we look for [tex]a_8[/tex]

[tex]a_8 = 90 + 30(8-1)[/tex]

[tex]a_8 = 90 + 30(7)[/tex]

[tex]a_8 = 300[/tex]

Answer:

[tex]\boxed{\text{300 ft}}[/tex]

Step-by-step explanation:

You have an arithmetic sequence in which

a₁ =  90

a₂ = 120

a₃ = 150

1. Calculate the explicit formula

This is an arithmetic sequence, because there is a constant difference of 30 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,  

aₙ = 90 + 30(n - 1) = 90 + 30n - 30

aₙ = 30n + 60

2. Calculate the eighth term

a₈ = 30 × 8 + 60 = 240 + 60 = 300

The difference between 7 cm and 4.4 cm is 2.6 cm. But since we need to round to the place value of the less precise measurement (7 cm), our final answer is 3 cm.

Explanation:

To find the difference between 7 cm and 4.4 cm, we simply subtract the smaller number from the larger one. So, we have 7 cm - 4.4 cm which equals 2.6 cm. However, we need to round to the place value of the less precise measurement.

evaluate h(x)=2.8x^3+0.01x^2 - 1 for x=1 and x=2

Answers

Answer:

h(1) = 1.81 and h(2) = 21.44

Step-by-step explanation:

* Lets read the problem and solve it

- Evaluate means find the value, so evaluate h(x) means find the value

 of it at the given values of x

∵ h(x) = 2.8x³ + 0.01x² - 1

∵ x = 1 and x = 2

- Then find h(1) by substitute x by 1 and find h(2) by substitute x by 2

# At x = 1

∴ h(1) = 2.8(1)³ + 0.01(1)² - 1

∴ h(1) = 2.8(1) + 0.01(1) - 1

∴ h(1) = 2.8 + 0.01 - 1

∴ h(1) = 1.81

# At x = 2

∴ h(2) = 2.8(2)³ + 0.01(2)² - 1

∴ h(2) = 2.8(8) + 0.01(4) - 1

∴ h(2) = 22.4 + 0.04 - 1 ⇒ simplify

∴ h(2) = 21.44

Help

Answers

Answer:

[tex]y = \frac{1}{2}x+10[/tex]

Step-by-step explanation:

The given path is:

y = -2x+5

Comparing with the standard form of equation:

y = mx+b

So,

m = -2

We know that product of slopes of two perpendicular lines is -1

Let m1 be the slope of the perpendicular line

m*m1=-1

-2*m1 = -1

m1 = -1/-2

m1 = 1/2

So the slope of perpendicular path is 1/2.

Since the new path passes through (-2,9)

[tex]9 = \frac{1}{2}(-2) +b\\9 = -1 +b\\b = 10[/tex]

Putting the values of m and b in standard form

[tex]y = \frac{1}{2}x+10[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

(1)

let (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 4), then

m = [tex]\frac{4+1}{4-0}[/tex] = [tex]\frac{5}{4}[/tex]

Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = [tex]\frac{5}{4}[/tex] x - 1 ← in slope- intercept form

(2)

let (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (1, - 6), then

m = [tex]\frac{-6-3}{1-4}[/tex] = [tex]\frac{-9}{-3}[/tex] = 3, hence

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 3), then

3 = 12 + c ⇒ c = 3 - 12 = - 9

y = 3x - 9 ← in slope- intercept form

According to this diagram what is cos 16

Answers

Answer:

Option: B is the correct answer.

         B)    [tex]\dfrac{24}{25}[/tex]

Step-by-step explanation:

We know that the cosine trignometric ratio corresponding to a angle theta(θ) is defined as the ratio of the adjacent side to the angle theta to the hypotenuse of the triangle containing θ as one of the angle.

By looking at the figure we observe that the triangle is a right angled triangle and the length of the side adjacent to angle 16° is: 24 and the hypotenuse of the triangle is: 25.

Hence, we get:

[tex]\cos 16=\dfrac{24}{25}[/tex]

According to the given figure, the value of Cos 16° = 24/25.

Hence the correct option is B.

Given that a right triangle with hypotenuse 25, base 24 and the perpendicular is 7 units.

We need to find the value of Cos16°.

To find the value of cos(16°) in the given right triangle, we can use the trigonometric ratio for cosine:

cos(θ) = adjacent side / hypotenuse

In this case, θ = 16°, and we know the adjacent side is the base of the right triangle, which is 24 units, and the hypotenuse is 25 units.

Now, plug the values into the formula:

cos(16°) = 24 / 25

Hence the value of Cos(16°) = 24 / 25

Hence the correct option is B.

julia collects colored beads for craft projects. Of julia's beads, 4/9 are silver, 1/5 are, gold and 1/4 are blue. The rest of the beads are red. Which expression give the closest estimate of the fraction of red beads Julia has?

i need an explanation on how to solve it

Answers

Answer:

19 red beads

Step-by-step explanation:

We first need to find a common denominator of 4/9, 1/5 and 1/4.

The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.

Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.

Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.

Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.

180 - (silver+gold+blue) = red beads

180-161 = 19 red beads b/c ----->

80+36+45+19 = 180

Final answer:

To find the estimate of beads that are red, you add the fractions of silver, gold, and blue beads first and subtract that from the total. In this case, it is estimated that the red beads are 19/180 of Julia's total collection.

Explanation:

To find the fraction of the red beads that Julia collects for her craft projects, we first need to sum up the fractions of the silver, gold, and blue beads as these are given fractions.

By addition, we have 4/9 (silver beads) + 1/5 (gold beads) + 1/4 (blue beads). Add these fractions together to get the total fraction of non-red beads. Now, to get the fractions into a form that's easier to add, find the least common denominator (LCD).

The LCD of 9, 5, and 4 is 180. Then, convert each fraction to have this denominator: 80/180 (silver) + 36/180 (gold) + 45/180 (blue). Now you can add these fractions directly to get 161/180.

Since the total should be 1 (or 180/180 to keep the denominator constant), to find the fraction of the red beads, subtract the sum of the other beads from 1. Thus, 1 - 161/180 = 19/180. Therefore, Julia’s collection consists of approximately 19/180 red beads.

Solve by taking the square root of both sides 4(x-4)^2-180=0

Answers

Answer:

x = 4 ± 3[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Given

4(x - 4)² - 180 = 0 ( add 180 to both sides )

4(x - 4)² = 180 ( divide both sides by 4 )

(x - 4)² = 45 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{45}[/tex] = ± 3[tex]\sqrt{5}[/tex]

Add 4 to both sides

x = 4 ± 3[tex]\sqrt{5}[/tex]

The value of x is equal to [tex]4 +3\sqrt{5}[/tex] and [tex]4 -3\sqrt{5}[/tex] by solving the quadratic equation that is taking the square root of both sides and also by using the concept of transposition.

Given the quadratic equation [tex]4(x-4)^2-180=0[/tex] by taking the square root of both sides

To solve a quadratic equation [tex]4(x-4)^2-180=0[/tex] by taking the square root of both sides, follow steps:

Step 1: Consider the given quadratic equation:

[tex]4(x-4)^2-180=0[/tex]

Add by  18  on both sides, gives;

[tex]4(x-4)^2-180+180=0+180[/tex]

On operating algebra sum results:

[tex]4(x-4)^2=180[/tex]

Step 2: Isolate the LHS [tex]4(x-4)^2[/tex]  from number 4 by dividing both sides by 4 yields:

[tex]\frac{4(x-4)^2}{4} =\frac{180}{4}[/tex]

On cancelation of 4 on LHS and divide 180 by 4 on RHS results in :

[tex](x-4)^2=45[/tex]

Factorize RHS with a perfect square 9 :

[tex](x-4)^2=9\times5[/tex]

Step 3: Taking the square root of both sides results :

[tex]\sqrt{(x-4)^2} = \sqrt{9\times5}[/tex]

On taking square roots results:

[tex](x-4) = \pm3\sqrt{5}[/tex]

Add by 4 on both sides, gives:

[tex]x=4 \pm3\sqrt{5}[/tex]

Therefore, the value of x is equal to [tex]4 +3\sqrt{5}[/tex] and [tex]4 -3\sqrt{5}[/tex] by solving the quadratic equation that is taking the square root of both sides and also by using the concept of transposition.

Express cos(27pi/8) as a trigonometric function of an angle in Quadrant I.

Answers

Answer:

The equivalent trigonometric ratio in Quadrant I is [tex]-\cos (\frac{3\pi}{8})[/tex]

Step-by-step explanation:

The terminal side of [tex]\frac{27\pi}{8}[/tex] is in the 3rd quadrant.

The principal angle is [tex]\frac{3\pi}{8}[/tex]

In other words, the terminal side of [tex]\frac{27\pi}{8}[/tex]  makes an acute angle of [tex]\frac{3\pi}{8}[/tex] radian with the positive x-axis. Acute angles are in the first quadrant.

Since the cosine ratio is negative in the 3rd quadrant,

[tex]\cos (\frac{27\pi}{8})=-\cos (\frac{3\pi}{8})[/tex]

The arc length s cut off by a central angle of 6 degrees

[tex]$s=\frac{3 \pi}{10} f t$[/tex].

How to estimate arc length?

Let 's' define the arc length, '[tex]$\theta$[/tex]' define the central angle in radians and 'r' be the radius of the circle. Then a central angle of '[tex]$\theta$[/tex]' radians in a circle of radius r subtends an arc of length.

We must define [tex]$6^{\circ}$[/tex] in radians

[tex]$s=r \theta$[/tex]

[tex]$180^{\circ}-\pi \mathrm{rad}$[/tex]

[tex]$6^{\circ}-\theta \mathrm{rad}$[/tex]

Then

[tex]$\theta=\frac{6}{180} \cdot \pi=\frac{\pi}{30}$$[/tex]

The arc length s cut off by a central angle of 6 degrees

[tex]$s=9 f t\left(\frac{\pi}{30}\right)=\frac{3 \pi}{10} \mathrm{ft}$$[/tex]

[tex]$s=\frac{3 \pi}{10} f t$[/tex].

Therefore, the arc length s cut off by a central angle of 6 degrees is

Which expression is equivalent to 5^ square root 32x5^ y10^ z15^

Answers

Answer:

Option B is correct.

Step-by-step explanation:

[tex]\sqrt[5]{32x^5y^10z^15}[/tex]

We need to solve the above expression.

32 = 2x2x2x2x2 = 2^5

and we know 5√ = 1/5

solving

[tex]=\sqrt[5]{2^5x^5y^{10}z^{15}}\\=(2^5)^{1/5}(5x^5)^{1/5}(y^{10})^{1/5}(z^{15})^{1/5}\\=2xy^2z^3[/tex]

We have the equation of the line in the point-slope form:

[tex]y-4=\dfrac{3}{4}(x+8)[/tex]

Convert it to the standard form:

[tex]y-4=\dfrac{3}{4}(x+8)[/tex]        multiply both sides by 4

[tex]4y-16=3(x+8)[/tex]          use the distributive property

[tex]4y-16=3x+24[/tex]           add 16 to both sides

If the graph of the following parabola is shifted one unit left and two units up, what is the resulting equation in vertex form? x^2=12

Answers

ANSWER

[tex]{(x + 1)}^{2} =12(y - 2)[/tex]

EXPLANATION

The original parabola has equation

[tex] {x}^{2} = 12y[/tex]

This parabola has its vertex at the origin:

If the parabola is shifted one unit left and two units up, then its new vertex is at (-1,2).

The equation of the new parabola is now of the form:

[tex] {(x - h)}^{2} =1 2(y - k)[/tex]

where (h,k) is the vertex.

Substitute the vertex to get:

[tex] {(x - - 1)}^{2} =12(y - 2)[/tex]

[tex]{(x + 1)}^{2} =12(y - 2)[/tex]
