Answer:If A is at point (x,y), then A' would be at point (-x,-y). Same goes for points B and C.

Step-by-step explanation:

The 8th term of the given geometric sequence is -163840;

Given sequence 10, -40, 160,..... is a geometric progression;

Here, a = 10; r = -4;

The nth term of a geometric progression is given by aₙ = a(rⁿ⁻¹);

Therefore;

a₈ = 10(-4)⁸⁻¹ = 10(-4)⁷ = -163840;

A sort of sequence known as geometric progression (GP) is one in which each following phrase is created by multiplying each preceding term by a fixed number, or "common ratio." This progression is sometimes referred to as a pattern-following geometric sequence of numbers.

Answer:

C) y = 3x-5 is the answer.

Step-by-step explanation:

take two points,

(2,1) and (4,7)

slope(m) = (7-1)/(4-2)

m = 6/2

m = 3

now,

y = mx+b

1 = 3×2+b

1 = 6+b

b = -5

now

y = mx+b

y = 3x-5

The scale factor that was used to convert triangle ABC into the image in A ' B ' C ' is 1 / 2.

To find the scale factor, you need to find the length of a side of triangle ABC and then the length of the corresponding side in A ' B ' C '.

The side length we will pick is AB which is:

= 6 - 2

= 4 units

The side length of the other triangle is A' B' :

= 3 - 1

= 2 units

The scale factor is:

= 2 / 4

= 1 / 2

In rectangular pyramid VWXYZ where WX>XY, then slant height VA shorter than the slant height VB.

As given,

In rectangular pyramid VWXYZ,

Draw perpendicular height VM and join AM and BM such that MAXB is a rectangle

AM=BX and BM=AX

So, BM>AM  __(1)

In right triangle VMA and VMB,

VA and VB are slant height (hypotenuse)

VM=perpendicular height

Answer:

12.5ft tall.

Step-by-step explanation:

The volume of a rectangular box is V = L x W x H

We are given volume, length, and width, allowing us to solve for height.

3000 ft^3 = 96 ft x 2.5 ft x H ft

Divide both sides by 96 x 2.5 to isolate H

3000 / (96 x 2.5) = H

H = 12.5 ft.

Answer:

Step-by-step explanation:

It's given that One of the first electronic computer was in the shape of a huge box. It was 96 m long and 2.5 m wide.

Length of the box = 96 feet

Breadth of the box = 2.5 feet

Also The amount of space inside was approximately 3,000 cubic feet i.e volume of the box is 3000 ft³.

We know that volume of cuboid is calculated by,

96 × 2.5 × h = 3000

240 × h = 3000

h = 3000/240

h = 12.5 feet

Therefore, Height of the computer is 12.5 feet

A) The function that represents the average of the class is;

y = 65(1.011)^(x)

B) The average of the class after one week will be expressed as;

y = 70.17

The general formula for the nth term of a exponential function is;

y = ab^(x)

where;

a is initial amount

b is growth factor

x is the amount of periods being considered

Now, we are told that the initial score for the exam was 65. Thus;

a = 65

The growth factor is 1.1% and this is; b = 1.011

Thus, the function that represents the average of the class is;

y = 65(1.011)^(x)

The average of the class after one week will be expressed as;

y = 65(1.011)^(7)

y = 70.17

Answer:

Step-by-step explanation:

The length of the field is greater than the width by the expression \((14x - 3x^2 + 2y) - (5x - 7x^2 + 7y).\)

1. The length of the field is represented by the expression \(14x - 3x^2 + 2y.\)

2. The width of the field is represented by the expression \(5x - 7x^2 + 7y\).

3. To find the difference between the length and width, we subtract the width from the length: (\(14x - 3x^2 + 2y) - (5x - 7x^2 + 7y\)).

4. Simplifying the expression, we remove the parentheses: \(14x - 3x^2 + 2y - 5x + 7x^2 - 7y.\)

5. Combining like terms, we group the \(x^2\) terms together and the x terms together: \(-3x^2 + 7x^2 + 14x - 5x + 2y - 7y.\)

6. Simplifying further, we add the coefficients of like terms:\((7x^2 - 3x^2) + (14x - 5x) + (2y - 7y).\)

7. The simplified expression becomes: \(4x^2 + 9x - 5y.\)

8. Therefore, the length of the field is greater than the width by the expression \(4x^2 + 9x - 5y.\)

Answer:

  1/60 gallon

Step-by-step explanation:

You want to know what is left of 4/5 gallon of paint if 3/4 gallon was used to paint a doghouse, and 2/3 of the remaining amount was used to paint a door.

To find the amount remaining we subtract the amount used for the doghouse from the original amount:

  4/5 -3/4 = (16 -15)/20 = 1/20 . . . . . gallon

2/3 of that was used, so 1/3 of it remains:

  (1/3)(1/20 gallon) = 1/60 gallon

There is 1/60 of a gallon of paint left in the can.

Additional comment

In a standard size gallon paint can, that's about 0.11 inches of paint in the bottom.

Answer:

the solution to the system of equations is (x, y) = (3, -2).

Step-by-step explanation:

y = -2x + 4 (Equation 1)

y = x - 5 (Equation 2)

To solve for x, we can equate the right sides of the equations:

-2x + 4 = x - 5

Now, we can solve for x:

-2x - x = -5 - 4

-3x = -9

x = (-9) / (-3)

x = 3

Substituting the value of x back into Equation 2, we can solve for y:

y = 3 - 5

y = -2

Answer:

We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:  

Null hypothesis:\(p \leq 0.15\)  

Alternative hypothesis:\(p > 0.15\)  

And the best answer for this case would be:

Ha: p > 0.15

Step-by-step explanation:

Information given

n=250 represent the random sample taken

X=40 represent the number of people on the alumni mailing list

\(\hat p=\frac{40}{250}=0.16\) estimated proportion of people on the alumni mailing list  

\(p_o=0.15\) is the value to verify

z would represent the statistic

\(p_v\) represent the p value

Hypothesis to test

We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:  

Null hypothesis:\(p \leq 0.15\)  

Alternative hypothesis:\(p > 0.15\)  

And the best answer for this case would be:

Ha: p > 0.15

Testing the hypothesis, it is found that the alternative hypothesis is:

\(H_1: p > 0.15\)

At the null hypothesis, it is tested if the mail appeal is not effective, that is, if the population proportion is of at most 15% = 0.15, hence:

\(H_0: p \leq 0.15\)

At the alternative hypothesis, it is tested if the mail appeal is effective, that is, if the population proportion is above 15% = 0.15, hence:

\(H_1: p > 0.15\)
