which one of these numbers could form a triangle?

Answer:

Step-by-step explanation:

     Switching the order of the terms comes out as an equivalent expression.

Whatever A is, if we multiply it by 8 and add 2, it will be equivalent to the sum of the same number times multiplied by 8 and 2.

I hope that helps!

Answer:

2(a +4)

Step-by-step explanation:

Distributive property:  a*b + a * c = a*(b+c)

Factorize 2 & 8  and find GCF of 2 & 8

2 = 2

8 = 2* 2*2

GCF = 2

2a + 8 =  2a + 2*4

           = 2(a + 4)

Answer: See attached.

Step-by-step explanation:

   For [a], we graph the parent function (y = x²), but shift it downwards 2 units.

   For [b], we graph the parent function (y = x²), but shift it downwards 6 units, shift it to the right 2 units, and apply a compress factor of 3.

This is a difference of squares, so its the square of the first term minus the square of the second term.

The error of Fatima is: C. She applied the exponent -2 to "4(-2) instead of only to "(-2).

An exponent in any expression is the letter or number on the right of a base in an expression.

In the evaluated expression shown, the base that the exponent "-2" applies to is "m", and does not include 4. If we substitute the value of m = -2, into the evaluated expression, the base that the exponent "-2" applies to is "-2" and does not include "4".

Therefore, Fatima's mistake is: C. She applied the exponent -2 to "4(-2) instead of only to "(-2).

The maximum height of the rocket is 78.4m

Given the function that represents the height of a function expressed as:

h(t) = -4.9t² +9.8t + 73.5.

The rocket will reach its maximum height at the point where h'(t) = 0

h'(t) = -9.8t +9.8

Equate to zero

0 = -9.8t + 9.8

9.8t = 9.8

t = 1

Substitute

h(1) = -4.9(1)²+9.8(1) + 73.5

h(1) = 4.9 + 73.5

h(1) = 78.4m

Hence the maximum height of the rocket is 78.4m

The height of the smaller building is 94.63 feet, computed using the trigonometric ratios.

In the question, we take AB to be the taller building, where A is its top and B is its base, CD to be the shorter building, where C is its top and D is its base, and CE to be the perpendicular from C to AB.

Given that the horizontal distance between the two buildings is 260 feet, we can say that BC = CE = 260 feet.

The angle of elevation from the top of the shorter building to the top of the taller building is 30°, that is, ∠ECA = 30°.

The angle of depression from the top of the shorter building to the base of the taller building is 20°, that is, ∠ECB = 20°.

When ∠ECB = 20°, then ∠CBD = 20°, as they are alternate angles.

We are asked to find the height of the shorter building, that is, we are asked to find CD.

In ΔCBD,

tan ∠CBD = CD/BD {perpendicular/base},

or, tan 20° = CD/260,

or, CD = 260*tan 20° = 260*0.36397023426 {∵ tan 20° = 0.36397023426},

or, CD = 94.6322609092.

Therefore, the height of the smaller building is 94.63 feet, computed using the trigonometric ratios.

The solution to the system of equations is the point of intersection of the two lines which is at; (0.88, 0.65)

The two simultaneous equations of the line are given as:

y = -²/₅x + 1 -----(1)

y = 3x – 2   -----(2)

Subtracting equation 1 from equation 2 gives;

3.4x - 3 = 0

3.4x = 3

3.4x/3.4 = 3/3.4

x = 0.88

Substitute x = 0.88 in equation 2 to get;

y = 3(0.88) - 2

y = 2.65 - 2

y = 0.65

Thus, the solution to the system of equations is the point of intersection of the two lines which is at (0.88, 0.65).

The ratio of the combined volume of these pyramids to the volume of the prism as a fraction is equal to 1/3.

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × b × h

Where:

Since both pyramids have the same base area as the prism, their combined volume is given by:

Combined volume = (1/3 × b × h) + (1/3 × b × h)

Combined volume = 2/3 × b × h

Also, the volume of this prism = 1/2 × b × h

Thus, the ratio is given by:

Ratio = (2/3 × b × h)/(1/2 × b × h)

Ratio = 2/3 × 1/2

Ratio = 1/3.

The length of DC based on the information given about the triangle is 19.37.

Based on the given information, it should be noted that:

AB² = AD² + BD²

25² = AD² + 5²

625 = AD² + 25

AD² = 625 - 25

AD² = 600

AD = √600

AD = 24.5

DC² = AD² + - AB² (Pythagoras theorem)

DC² = 24.5² + 15²

DC² = 375.25

It has the same slope and the same y-intercept, that is, option a is the right choice.

A linear function in the slope-intercept is written as y = mx + b, where m represents the slope of the line and b represents the y-intercept.

We are given two linear functions and are asked to compare them.

First linear function:

Slope (m) = -7/9.

y-intercept (b) = 3.

Therefore, the linear function is: y = (-7/9)x + 3.

Second linear function:

Function given: y + 11 = (-7/9)(x - 18)

or, y + 11 = (-7/9)x + (-7/9)(-18)

or, y = (-7/9)x + 14 - 11 = (-7/9)x + 3.

Therefore, slope (m) = (-7/9)

y-intercept (b) = 3.

Step-by-step explanation:

Solving for x

0 < 3x - 2 < 1

Add 2 to each side
