I will tell u how to solve it. First cut of the top triangle and do 25 times 15 divided by 2 . Then u do the area of the rectangle by doing 30 times 15. Then u add the two numbers together and u have ur final answer/area. Hope
this helps!

Okay, now let cut this complex figure to get the two shape-rectangle and triangle, now the rectangle has has the area of 30 times 15 which equal 450 square mm, and the triangle has an area of 1/2 times 10 times 15 which equal 75 square mm, so the area of the composite figure is 525 square mm. Hope it help!

The reciprocal parent function is translated 5 units right and 3 units up. Write an equation to represent the new function.

ladessa [460]

Answer:

The new function is $y=\frac{1}{x-5}+3$ , where x ≠ 5

Step-by-step explanation:

The reciprocal parent function is $f(x)=\frac{1}{x}$ , where x ≠ 0

The translation of f(x) to the right h units is f(x - h)

The translation of f(x) up k units is f(x) + k

The translation of f(x) to the right h units and up k units is f(x - h) + k

∵ The equation of the reciprocal parent function is $y=\frac{1}{x}$

∵ The function is translated 5 units right

∴ h = 5

- That means 5 is subtracted from x ⇒ (x - 5)

∵ The function is translated 3 units up

∴ k = 3

- That means y added by 3

∴ $y=\frac{1}{x-5}+3$

The new function is $y=\frac{1}{x-5}+3$ , where x ≠ 5

Question 3,4&5 Cindy bought a car for $21,330. A few years later she sold the car for $19,700.find the percent of change in

san4es73 [151]

The change in value was 8% which amounts to $1630

Further explanation:

The change in value is calculated by using the initial price and selling price of the car.

Given

Purchase Price = P = $21330

Selling Price = S = $19700

As the selling price is less than the purchase price, Cindy had loss.

$Loss=L= Cost\ price-selling\ price\\=21330-19700\\=\$1630$

Percentage of loss will be calculated as:

$Percent\ loss=\frac{1630}{21330}*100\\=8\%$

The change in value was 8% which amounts to $1630

Find two consecutive numbers whose squares differ by 45

Wittaler [7]

Answer:

The 2 numbers are 22 and 23

Step-by-step explanation:

let the two numbers be x and x+1

according to the question:

(x+1)^2 - x^2 = 45

x^2+1+2x - x^2 = 45

2x + 1 = 45

2x= 44

x = 22

the other number is x+1 = 22+1 = 23

therefore, the two consecutive numbers are 22 and 23
