Vanessa purchased a smart TV for $1,500 on a payment plan. Four months after purchasing the TV, her balance was $1,200. 7 months

fredd [130]

Answer:

The expression for her balance is "B(t) = -75*t + 1500". It'll take her 20 months to pay off the loan.

Step-by-step explanation:

We are looking for a function that has the following points:

B(0) = 1500

B(4) = 1200

B(7) = 975

Between B(4) and B(7), there was a variation of 3 months and a variation of -225 on her balance, thefore for each month that passed there was a variation of -75. Thefore, the expression for her ballance is:

B(t) = -75*t + 1500

To check if this expression is valid, we will apply the values provided on the problem:

B(0) = -75*0 + 1500 = 1500 (valid)

B(4) = -75*4 + 1500 = -300 + 1500 = 1200 (valid)

B(7) = -75*7 + 1500 = -525 + 1500 = 975 (valid)

When she pays of her loan, B(t) = 0, so we need to solve for t as shown below:

B(t) = -75*t + 1500 = 0

-75*t + 1500 = 0

75*t = 1500

t = 1500 / 75 = 20 months

It'll take her 20 months to pay the loan.

What is the hypotenuse of a triangle with 4 ft and 5 ft

sergeinik [125]

Answer:

$\Large\text{The hypotenuse is}\ \sqrt{41}\ ft\approx6.4\ ft$

Step-by-step explanation:

$\text{Use the Pythagorean theorem:}$

$a^2+b^2=c^2$

$\text{a, b - legs}\\\text{c - hypotenuse}$

$\text{We have the legs 4ft and 5ft. Substitute:}$

$c^2=4^2+5^2\\\\c^2=16+25\\\\c^2=41\to c=\sqrt{41}$
