Your answer would be 122,400.

<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.

It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.

Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.

Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)

finlep [7]

Answer:

g(f(x))=x^2 + 14x + 48

Step-by-step explanation:

you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.

Give the first 4 terms of a sequence who has the explicit formula an = 4n – 13

andreev551 [17]

Step-by-step explanation:

from,

An = 4n -13

A1 = 4 (1) - 13

> A1 = -9

A2 = 4(2) - 13

> A2 = -5

A3 = 4(3) - 13

> A3 = -1

A4 = 4(4) - 13

> A4 = 3

Answer:

A. $\frac{(a-b)^{2} +b^{2} }{a^{2}}$

Step-by-step explanation:

So to get the area of a square, we need to find the length of one side.

We know the length of the larger square is a, so the area of the larger cube is $a^{2}$

We can find the length of a side of the smaller square by using pythagoreans theorem to find the hypotenuse of the triangle formed in the bottom left corner. The length of one side along the x axis is a - b, and the length of the other side, along the y-axis, is b.

We can plug it into pythagoreans theorem to get

$(a-b)^{2} +b^{2} = C^{2}$ (C represents the length of one side of the smaller square, and the hypotenuse of the triangle)

$C = \sqrt{ (a-b)^{2} +b^{2}}$

The area of the smaller triangle is C squared to the area of the smaller triangle is

$(a-b)^{2} +b^{2}$

To get the ratio of the smaller square in comparison to the larger square we divide the area of the smaller square by the area of the larger square.

So the ratio should be

$\frac{(a-b)^{2} +b^{2} }{a^{2}}$

Find the value of x. please help me with my test

Lady bird [3.3K]

Step-by-step explanation:

180 -angled triangle,

180-56 = 124

124/2 = 62 (each corner of the right triangle)

then find the corner below

the rectangle has right angles on the right side

x = 90-62

= 28

Find the value of X in the triangle shown.

zalisa [80]

X = 12

Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x
