0 59. 16/week
$11.45

Answers

Answer:

The answer is A. -11.45

Step-by-step explanation:

By using expression for the rate of change in prices between week 1 and week 5 will be -$11.45.

Rate of change is given by the expression,

Rate of change = [tex]\frac{\triangle y}{\triangle x}[/tex]

= [tex]\frac{\text{Change in price}}{\text{Change in weeks}}[/tex]

By using the given expression, rate of change of prices between week 1 and week 5 will be,

Rate of change = [tex]\frac{694.99-740.79}{5-1}[/tex]

= [tex]-\frac{45.8}{4}[/tex]

= [tex]-11.45[/tex]

Therefore, rate of change in the price of washer and dryer pair between week 1 and week 5 will be -$11.45 per week.

An unusually wet spring has caused the size of a mosquito population in some city to increase by 8% each day. If an estimated 180,000 mosquitoes are in the city on May , find how many mosquitoes will inhabit the city on May . Use y= 180,000 where x is number of days since May .

Answers

Answer:

The number of mosquitoes that will inhabit the city on May 25 is 4,471,200.

Step-by-step explanation:

Note: This question is not complete as some important figures and points are omitted. The complete question is therefore provided before answering the question as follows:

An unusually wet spring has caused the size of a mosquito population in some city to increase by 8% each day. If an estimated 180,000 mosquitoes are in the city on May 12, find how many mosquitoes will inhabit the city on May 25. Use y= 180,000(1.08)x where x is number of days since May 2.

The explanation to the answer is now given as follows:

Given;

y = 180,000(1.08)x = 180,000 * 1.08 * x .................... (1)

Where;

y = Number of mosquitoes that will inhabit the city on May 25 = ?

x = Number of days since May 2 = 25 - 2 = 23

Substituting for x = 23 into equation (1), we have:

y = 180,000 * 1.08 * 23

y = 4,471,200

Therefore, the number of mosquitoes that will inhabit the city on May 25 is 4,471,200.

The image below shows two dilated figures with lines AB and A'B' drawn. If the larger figure was dilated using a scale factor of 3, what relationship do lines AB and A'B' have? (10 points)

Answers

Answer:

They have the same side lengths/angles except one is smaller than the other

Step-by-step explanation:

the smaller one is a "mini" of the larger one. a exact copy

The dilation is solved and the scale factor of line is A'B' = 3AB

What is Dilation?

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the scale factor of the dilation be represented as k

Now , the scale factor k = 3

So , the ratio of the corresponding sides is given by

A'B' / AB = 3

Multiply by AB on both sides , we get

A'B' = 3AB

Hence , the dilation is simplified as A'B' = 3AB

Triangle CAT is an isosceles triangle with base angles C and T each represent by (3x + 11) degrees, while angle A is represented by (9x + 8) degrees. Find the measure of angle C.

Answers

Answer:

Angle C = 41°

Step-by-step explanation:

Given:

Angle C = (3x + 11) degree

Angle T = (3x + 11) degree

Angle A = (9x + 8) degree

Find:

Angle C

Computation:

Using angle sum property

(3x + 11) + (3x + 11) + (9x + 8) = 180

15x + 30 = 180

x = 10

So,

Angle C = (3x + 11) degree

Angle C = 3(10) + 11

Angle C = 41°

Which expression is a factor of 21 x2 + 13 x-20

Answers

Answer:

(7x−5)(3x+4)

Step-by-step explanation:

I think this is the answer

Answer:

(7x−5)(3x+4)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant -21 • 20 = -420

Step-2 : Find two factors of -420 whose sum equals the coefficient of the middle term, which is 13 .

-420 + 1 = -419

-210 + 2 = -208

-140 + 3 = -137

-105 + 4 = -101

-84 + 5 = -79

-70 + 6 = -64

-60 + 7 = -53

-42 + 10 = -32

-35 + 12 = -23

-30 + 14 = -16

-28 + 15 = -13

-21 + 20 = -1

-20 + 21 = 1

-15 + 28 = 13 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 28

-21x2 - 15x + 28x + 20

Step-4 : Add up the first 2 terms, pulling out like factors :

-3x • (7x+5)

Add up the last 2 terms, pulling out common factors :

4 • (7x+5)

Step-5 : Add up the four terms of step 4 :

(-3x+4) • (7x+5)
