Answer:

44   You will get the 2x and 88 and divide 88 by 2x

Step-by-step explanation:

Answer:  The required value of x is 22.

Step-by-step explanation:  Given that B and F are the midpoints of the sides AC and AE of triangle ACE.

Also, BF = 2x  and  CE = 88.

We are to find the value of x.

Midpoint theorem :  If a line segment joins the midpoints of any two sides of a triangle, then it is parallel to the third side and its length is equal to half of the length of the third side.

From triangle ACE, we have

B and F are the midpoints of the sides Ac and AE respectively, so BF will be parallel to CE and its length will ne half of the length of side CE.

Therefore,

[tex]BF=\dfrac{1}{2}\times CE\\\\\Rightarrow 2x=\dfrac{1}{2}\times88\\\\\Rightarrow 2x=44\\\\\Rightarrow x=\dfrac{44}{2}\\\\\Rightarrow x=22.[/tex]

Thus, the required value of x is 22.

Question 1. 2P + 14 = 0

Step 1. You need to subtract 14 from both sides.

2p+14−14=0−14

2p=−14

Step 2. Then divide both sides by 2.

2p /2 = −14 /2

Answer:  p=−7

Question 2.  - 2/3 w + 5 = 4

Step 1. Subtract 5 from both sides.

−2 /3 w+5−5=4−5

Step 2. Then multiply both sides by 3/(-2).

( 3 /−2 )*( −2 /3 w)=( 3 /−2 )*(−1)

Answer: w=  3 /2

Question 3. 5d - 1 = - 11

Step 1. First add 1 to both sides.

5d−1+1=−11+1

5d=−10

Step 2. Divide both sides by 5.

5d /5 = −10 /5

Answer: d=−2

Answer:

The height of the statue is 21.4 feet

Step-by-step explanation:

We are given

A person is standing 50 ft from a statue

The person looks up at an angle of elevation of 16 degree when staring at the top of the statue

hen the person looks down at an angle of depression of 8 degree when staring at the base of the statue

Firstly, we will draw diagram

In triangle ABF:

FC=50

we can use trig formula

[tex]tan(16)=\frac{y}{50}[/tex]

[tex]y=50tan(16)[/tex]

[tex]y=14.33727ft[/tex]

now, we can find x

In triangle DEF:

we can use trig formula

[tex]tan(8)=\frac{x}{50}[/tex]

[tex]x=50tan(8)[/tex]

[tex]x=7.0270ft[/tex]

we can see that

height of statue =x+y

so, the height of statue is

[tex]=14.33727+7.0270[/tex]

[tex]=21.4ft[/tex]

The height of the statue to the nearest tenth of a foot is 21.4 ft and this can be determined by using the trigonometric properties

Given :

Refer to the diagram attached below.

From the diagram in triangle ABF:

[tex]\rm tan(16)=\dfrac{a}{50}[/tex]

a = 14.33 ft

From the diagram in triangle DEF:

[tex]\rm tan(8)=\dfrac{b}{50}[/tex]

b = 7.02 ft

Now, the height of the statue is given by:

[tex]\rm Height = a +b[/tex]

Height = 14.33 + 7.02

Height = 21.4 ft

The height of the statue to the nearest tenth of a foot is 21.4 ft.

Answer:

We can translate Circle C (x+6, y-2) to have the same center as D. The ratio of radius to radius is 10/5=2. Scale factor 2 from C to D.

Step-by-step explanation:

Similar objects are objects which are the same shape but not the same size. This means they have the same angle measures and a scale factor between the side lengths. To show similarity, we can use transformations and proportions. We can translate to shift the object, dilation to increase or decrease size and so forth. We use proportions to find scsale factor or missing length.

We have a circle. Circles do not have a specific angles and all circles have 360 degrees. They do not have sides but do have radius. All circles are similar because all are the same shape - a fixed center with points equidistant from the center (the radius). To show similar we can translate the circle so the centers are the same and create a ratio between the radius.

We can translate Circle C (x+6, y-2) to have the same center as D. The ratio of radius to radius is 10/5=2. Scale factor 2 from C to D.

Answer:

ASA

Step-by-step explanation:

We're already given a pair of congruent angles and sides

∠DEA and ∠BEC are congruent because they are verticle angles

So we can use ASA to prove the triangle ADE and triangle CBE congruent

To prove that triangle ADE is congruent to triangle CBE, you can use the SSS, SAS, or ASA congruence theorems depending on the given information. The Pythagorean theorem or trigonometry can be used if applicable. You must match corresponding sides or angles to decide which theorem to use.

There are several congruence theorems for triangles including Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA). To determine which theorem to use in order to prove that triangle ADE is congruent to triangle CBE, you need to determine what information is given in the problem. For example, if you know that corresponding sides and angles are equal, you might use the SSS postulate, the SAS postulate, or the ASA postulate respectively.

If right angles are involved, we could also factor in the Pythagorean theorem to help establish side lengths - this theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b), expressed as: a² + b² = c². Solving for c gives us c = √a² + b². Similarly, if vectors and trigonometry are relevant factors in deriving your triangle sides or angles, they can also be used in establishing congruence.

Answer:

The 3rd equation on the left column  and second one on the right column.

Step-by-step explanation:

These 2 equations have same  coefficients of x and y if we divide the first one by 4 and the second by 2.

This gives the 2 equations

x^2 + y^2 - 4x + 6y - 7 = 0

x^2 + y^2 - 4x + 6y - 20 = 0

If we compete the square on these we get

(x - 2)^2 + (y + 3)^2 =  20

(x - 2(^2 + (y + 3)^2 =  33

These are in standard form . The center is the same (2, -3) but the radii are different so they are concentric.

In mathematics, concentric circles have the same center but different radii. Their general equation is (x-h)²+ (y-k)² = r², sharing the same (h, k) coordinates. Examples include equations like (x - 2)² + (y - 3)² = 4 and (x - 2)² + (y - 3)² = 9.

In mathematics, concentric circles are circles that share the same center but have different radii. The general equation of a circle is given by (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius. Two such equations will represent concentric circles if and only if their center coordinates (h, k) are the same.

For example, consider the equations:

(x - 2)² + (y - 3)² = 4

(x - 2)² + (y - 3)² = 9

Both these circles have the center at (2, 3) but different radii (2 and 3 respectively), making them concentric circles.

Answer:

Yes, they are.

The margin of error is 0.97849

we are given

mean=235

so,

[tex]n=235[/tex]

standard deviation =7.5

so,

[tex]\sigma=7.5[/tex]

we know that

ME=2*standard error

and

[tex]SE=\frac{\sigma }{\sqrt{n} }[/tex]

If confidence level is 95%, then we can multiply by 1.96

so, we can multiply by 2 to get ME

now, we can use marginal error formula

[tex]ME=\frac{2\sigma }{\sqrt{n} }[/tex]

now, we can plug values

and we get

[tex]ME=\frac{2\times 7.5 }{\sqrt{235} }[/tex]

[tex]ME=0.97849[/tex]

The top-left graph is the correct representation of the function[tex]\( f(x) = 0.75^x \)[/tex]. It shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1).

The correct option is (A).

To determine which graph represents the function [tex]\( f(x) = 0.75^x \)[/tex], we should consider the key characteristics of an exponential function where the base is between 0 and 1:

1. As [tex]\( x \)[/tex]  increases, [tex]\( f(x) \)[/tex] should decrease because 0.75 raised to a higher power becomes smaller.

2. As [tex]\( x \)[/tex] decreases (becomes more negative), [tex]\( f(x) \)[/tex] should increase because 0.75 raised to a negative power becomes larger.

3. The graph will never touch the x-axis, as an exponential function does not cross the axis when the base is positive.

4. The y-intercept should be at [tex]\( f(0) = 0.75^0 = 1 \)[/tex] because any non-zero number to the power of 0 is 1.

Now let's evaluate the provided graphs with respect to these characteristics:

- Top-left graph:This graph shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1), which matches the behavior of [tex]\( f(x) = 0.75^x \)[/tex].

- Top-right graph:This graph increases as [tex]\( x \)[/tex] increases, which is not correct for [tex]\( f(x) = 0.75^x \)[/tex].

- Bottom-left graph:This graph also increases as [tex]\( x \)[/tex] increases, which does not match the expected behavior.

- Bottom-right graph:This graph shows a decreasing function as [tex]\( x \)[/tex]increases, but the y-intercept is not at (0, 1), so it does not represent [tex]\( f(x) = 0.75^x \)[/tex].

Based on this analysis, the top-left graph is the correct representation of the function[tex]\( f(x) = 0.75^x \)[/tex]. It shows a decreasing function as [tex]\( x \)[/tex] increases, and the y-intercept is at (0, 1).

Find the expression.

Let the number be M.

"Nine more than twice a number is less than negative nineteen".

We can write this statement as:

2M + 9 < -19

Find the number M.

2M + 9 < -19

2M + 9 < -19

2 x -15 + 9 = -19

-30 + 9 = -19

-21 < -19

This is true.

We see that all numbers below -14 will make the statement true.

So,

The numbers are -15, -16, -17, -18,..........-∞

Thus the numbers that make the statement true are ( -14, -∞ ) or [-15, -∞).

To solve the inequality, we need to translate the given statement into an algebraic expression and then solve for 'x' using subtraction and division.

To solve the inequality, we will translate the given statement into an algebraic expression. Let's say the number is represented by 'x'. 'Twice a number' can be written as 2x. 'Nine more than twice a number' can be written as 2x + 9.

So, the inequality becomes 2x + 9 < -19.

To solve for 'x', we subtract 9 from both sides of the inequality, giving us 2x < -28. Then, we divide both sides by 2, resulting in x < -14.

Therefore, any number less than -14 will make the statement true.

Answer:

x=34

Step-by-step explanation:

Please, see the attached file.

Thanks.

Answer:

Hence final answer is x=34

Step-by-step explanation:

∠ADC= ∠EDF {Vertically opposite angles are always equal}

∠ADC= 36°  {Given }

∠ADB= 36°...(i)  {Same angles}

∠ABI + ∠ABC = 180° {supplementry angles }

113° + ∠ABC = 180°  {Given }

∠ABC = 180° - 113°

∠ABC = 67°

∠ABD = 67° ...(ii)  {same angle}

We know that sum of all three angles of triangle is 180 degree so we can write:

∠ABD + ∠ADB + ∠BAD =  180°

67° + 36° + ∠BAD =  180°  {using (i) and (ii) }

67° + 36° + x°+43° =  180°  {from diagram }

146° + x° =  180°

x° =  180° - 146°

x° =  34°

Hence final answer is x=34

1. The equation of line is [tex]y=-\frac{1}{2}(x)+1[/tex].

2. The correct option is D.

Step-by-step explanation:

1.

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

The given equation of a line is

[tex]y=2x+8[/tex]

The slope of line is 2 and y-intercept is 8.

The product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]2\times m_2=-1[/tex]

[tex]m_2=-\frac{1}{2}[/tex]

The slope of required line is [tex]-\frac{1}{2}[/tex] and it passes through the point (6,-2).

The equation of required line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y+2=-\frac{1}{2}(x-6)[/tex]

[tex]y+2=-\frac{1}{2}(x)+3[/tex]

[tex]y=-\frac{1}{2}(x)+3-2[/tex]

[tex]y=-\frac{1}{2}(x)+1[/tex]

Therefore the equation of line is [tex]y=-\frac{1}{2}(x)+1[/tex].

Step-by-step explanation:

A = 1/2h (b1 + b2)

Divide both sides by 1/2 (b1 + b2)

h  =  A / 1/2 (b1 + b2)

h =  2A / (b1 + b2)

Answer:

2A /  (b1+b2)  = h

Step-by-step explanation:

The formula for the area of a trapezoid is

A = 1/2 (b1+b2) *h

We want to solve for h

Multiply each side by 2

2A = 2*1/2  (b1+b2) *h

2A =  (b1+b2) *h

Divide each side by  (b1+b2)

2A /  (b1+b2)  =  (b1+b2) / (b1+b2) *h

2A /  (b1+b2)  = h
