Answer:

v(x)=2200-N*110

the value of computer after 8 years is 1320

Step-by-step explanation:

at 0 years the value is 2200

after 6 years the value is 1540

we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110

where n is number of years

so after 8 years : v(8)=2200-8*110=1320$

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is $V=a^3$

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

$V=\frac{500}{4}=125\ ft^3$

Substitute in the formula to get the side,

$125=a^3$

$a=\sqrt[3]{125}$

$a=5\ ft$

We know, 1 feet = 12 inches

So, 5 feet = $5\times 12=60$ inches

Therefore, 60 inches long are the sides of the pillars.

If f(x) = x ² +1 and g(x) =3x+ 1,find [f(4)] ²

guajiro [1.7K]

Answer:

289

Step-by-step explanation:

We don't need $g$ at all for this.

We will need to know $f(4)$ before continuing...

$f(4)$ can be found by replacing $x$ in $f(x)=x^2+1$ with $4$ :

$f(4)=4^2+1$

$f(4)=16+1$

$f(4)=17$

-------------------

Now let's find $[f(4)]^2$ :

$[f(4)]^2$

$[17]^2$

$17(17)$

$289$
