Answer:

(- 1, 2)

Step-by-step explanation:

Given a quadratic in standard form y = ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = x² + 2x + 3 ← is in standard form

with a = 1 and b = 2, hence

[tex]x_{vertex}[/tex] = - [tex]\frac{2}{2}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding value of y

f(- 1) = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2

vertex = (- 1, 2 )

Step-by-step explanation:

It's a much more interesting problem when we have to estimate the shadow length from a photo.

The crater is a curvy bumpy surface, but let's approximate it as part of a sphere and just conflate the arc and chord length, so the 400 m shadow corresponds to a 400 m chord from the edge at the surface to the bottom.

The shadow as a chord forms a hypotenuse right triangle with the depth d being the leg opposite the 48 degree angle of the sun.

[tex] d = 400 \sin 48 \approx 297 \textrm{  m}[/tex]

Answer: 297 m

The depth is 297.26 m.

It is the application of trigonometry.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Given

The shadow is estimated to be 400 m long.

And the angle of elevation of the sun is 48°.

The depth of a crater.

Hypotenuse = 400m

Angle = 48°

The by the sine rule

[tex]\begin{aligned} \rm sin \theta &= \rm \dfrac{Depth}{Hypotenuse}\\\\\rm sin 48^o &= \rm \dfrac{depth}{400}\\\\\rm depth &= \rm sin 48^o * 400\\\\\rm depth &= 297.2579 \approx 297.26 \end{aligned}[/tex]

Thus, the depth is 297.26 m.

Step-by-step explanation:

Just took the test.

Answer:

I'm not sure if this is the answer answer but this what the graph is a parabola

The function represented by the graph is y = 1/4(x - 2)^2 + 1

What function does this graph represent?

From the question, we have the following parameters that can be used in our computation:

The graph

The graph is the graph of a quadratic function

By definition:

A quadratic function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

From the graph, we have

Vertex = (2, 1)

So, we have

y = a(x - 2)^2 + 1

Using the point (0, 2) on the graph, we have

a(0 - 2)^2 + 1 = 2

4a + 1 = 2

4a = 1

a = 1/4

So, we have

y = 1/4(x - 2)^2 + 1

Hence, the function this graph represent is y = 1/4(x - 2)^2 + 1

So we are given the following function: [tex]y=-(x + 2)^{2}[/tex].

Before we can solve this problem, we need to know the following:

Know we can solve the problem!

1. [tex]y=-(x + 4)^{2}[/tex]. Translated left by 2 units.

2. [tex]y=-(x + 2)^{2} - 2 [/tex] Translated down by 2 units

3. [tex]y=(x - 2)^{2}[/tex] Reflected across the x-axis and the y-axis

4. [tex]y= 2-(x + 2)^{2}[/tex] Translated up by 2 units

5. [tex]y=-(x)^{2}[/tex] Translated right by 2 units

6. [tex]y=(x + 2)^{2}[/tex] y = (x + 2)2 Reflected across the x-axis

Answer:

Opt B. y=5-3x

Step-by-step explanation:

We need to write the given equation in slope-intercept form, so we can obtain the slope and the 'y' axis intercept point.

To do this, we need to isolate 'y' variable with a possitive sign, hence we perform the following operation:

Subtraction of -5 in both sides of equality sign.

-y=3x-5

Lets multiply by -1 the equation from above:

y= 5-3x.

From the above we can find the slope, is the coefficient of x. in this case -3

And the y-intercept point is 5.

Answer:

2.4

Step-by-step explanation:

We have to find the mean first

[tex]Mean = \frac{Sum}{No.\ of\ values}\\ = \frac{2+4+7+2+3+7+9+3+1+7}{10}\\ = \frac{45}{10}\\ = 4.5[/tex]

Now we have to find deviations.

Note that the deviations are calculated by subtracting the mean from the value. The distance is always positive so the deviations will be positive

Value         Deviation

2                 2-4.5 = |-2.5| = 2.5

4                  4-4.5 = |-0.5| = 0.5

7                  7-4.5 = 2.5

2                 2-4.5 = |-2.5| = 2.5

3                 3-4.5 = |-1.5| = 1.5

7                  7-4.5 = 2.5

9                  9-4.5 = 4.5

3                 3-4.5 = |-1.5| = 1.5

1                 1-4.5 = |-3.5| = 3.5

7                  7-4.5 = 2.5

The last step is to find the mean of deviations.

[tex]Mean\ of\ deviations = \frac{(2.5+0.5+2.5+2.5+1.5+2.5+4.5+1.5+3.5+2.5}{10}\\ = \frac{24}{10} \\=2.4[/tex]

The mean absolute deviation of given data set is 2.4 ..

Answer:

So, Width  = 7/2 or 3.5

Length =  4

Step-by-step explanation:

Area of rectangle = 14 ft^2

Let width of rectangle 2 = x

and Length of rectangle = 2x-3

Formula used for area of rectangle

Area = Length * Width

14 = (2x - 3) x

14 = 2x^2 - 3x

=> 2x^2 -3x -14 = 0

Solving the quadratic equation using factorization

-28 x^2 = -7x * -4x

2x^2 -7x + 4x -14 = 0

x (2x -7) +2(2x-7) = 0

(x+2) (2x-7) =0

=> x + 2 =0 and 2x -7 = 0

x = -2 and x = 7/2

Since width cannot be negative so, x= 7/2

Width= x = 7/2

Length = 2x -3 => 2(7/2) - 3

=> 7 -3

=> 4

So, Width =  7/2 or 3.5

Length =  4.

Length= 2width-3

Width=x

Length=2x+3

X(2x-3)=14

x must equal 3.5

Length=4

Width=3.5

Now, substitute (0,0) in the inequalities:

0 ≥  2 and 0 ≤  3

This is not true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ - 3

This is not true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ 3

This is true.

Now, substitute (0,0) in the inequalities:

0 ≥ - 2 and 0 ≤ - 3

This is not true.

Therefore, we have found that the inequalities are y ≥ 3x - 2 and y ≤ x + 3. The correct answer is option C.

the equation that can be used to find width is B

Answer:

It's a

Step-by-step explanation:

I did it

What we are given:

r( x ) = x - 3

s( x ) = 4x²

We have to find:

( s + r )( x ) = ( x - 3 + 4x² )

→ 4x² + x - 3

( s - r )( x ) = ( x - 3 - 4x² )

→ -4x² + x - 3

For the last function, I am confused whether it is a multiplication or composite function, so I am going to do both.

Multiplication:

( x - 3 ( 4x² ))( 2 )

( 4x³ - 12x² )( 2 )

4(2)³ - 12(2)²

4(8) - 12(4)

32 - 48

→ -4

Composite function:

r(s(x))(2) = r(4x²) = 4x² - 3  = 4(2)² - 3 = 4(4) - 3 = 16 - 3

→13

Final answer:

The expressions for (s+r)(x) is 4x^2 + x - 3 and (s-r)(x) is 4x^2 - x + 3. The value of (s.r)(2) is 16.

Explanation:

To find the expression for (s+r)(x), we need to add the functions s(x) and r(x). Adding the two functions, we get (s+r)(x) = 4x^2 + (x-3). Simplifying this expression, (s+r)(x) = 4x^2 + x - 3.

To find the expression for (s-r)(x), we need to subtract the function r(x) from s(x). Subtracting the two functions, we get (s-r)(x) = 4x^2 - (x-3). Simplifying this expression, (s-r)(x) = 4x^2 - x + 3.

To evaluate (s.r)(2), we need to substitute 2 for x in the expression s(x) * r(x). Substituting 2 for x in the expression 4x^2, we get (s.r)(2) = 4(2)^2 = 16.

The answer is 8 times bigger.

Answer:

2times bigger.

Step-by-step explanation:

Original volume of a rectangular prism = length × width × height

V = lwh... (1)

If the original dimension is doubled

New volume V2 = 2l × 2w × 2h

V2 = 2(lwh)...(2)

Taking the ratio of both volumes

V2/V = 2(lwh)/lwh

V2/V = 2

V2 = 2V

This shows that the new volume was two times bigger than the original volume

Answer:

Each friend will get more than 4 whole bagels.

Step-by-step explanation:

First off, although the question asks for 13 bagels divided between 3 friends, let's use a number that results in a whole number when divided by 3, but is close to 13.

This number can be 12.

12 divided by 3 is 4, so each friend gets 4 bagels if there are a total of 12 bagels.

However, there are more than 12 bagels so we know that each of the the 3 friends will get more than 4 bagels each.

Each friend will get 4 whole bagels, with 1 bagel left over.

In a baker's dozen, there are 13 bagels. Hillary, Mark, and Tam share the bagels equally. To determine if each friend will get more than or fewer than 4 whole bagels, we divide the total number of bagels by the number of friends.

13 bagels / 3 friends = 4 remainder 1

Each friend will get 4 whole bagels, with 1 bagel left over.

Division is one of the four basic operations of arithmetic. The other operations are addition, subtraction, and multiplication. What is being divided is called the dividend, which is divided by the divisor, and the result is called the quotient.

A  = $2200(7.612) = $16,747.28

Step-by-step explanation:

You don't say whether this is simple interest or compound interest.  I will assume you meant compound interest, for which the appropriate formula is

A = P(1 + r)^t, where P is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.  Then:

A = $2200(1 + 0.0725)^29, or

A = $2200(1.0725)^29, or

A  = $2200(7.612) = $16,747.28

The amount in the account after 29 years will be approximately $8484.64.

To calculate the amount of money that will be in the account after 29 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount ($2200 in this case), r is the annual interest rate (7.25% or 0.0725 as a decimal), n is the number of times interest is compounded per year (in this case, it's compounded annually, so n is 1), and t is the number of years (29 in this case). Plugging in the values, we get:

A = 2200(1 + 0.0725/1)^(1*29)

A = 2200(1.0725)^29

A ≈ $8484.64
