the perimeter of an isosceles trapezoid is 62 cm. if three sides are equal in length and the fourth side is 10 cm longer, find t

Alja [10]

Perimeter = sum of all the sides
let x = one side
longer side = x + 10
Perimeter = x + x + x + x + 10
62 = 4x + 10
4x = 52
x = 13
Longer side = 23

Area = (10+23)x2/10
= 6.6

What is the annual compound interest rate for an investment account modeled by the function y=12⋅1.18t ?

NikAS [45]

Answer:

The interest rate for the given investment is 18%.

Step-by-step explanation:

We are given that,

The function representing the investment model is, $y=12(1.18)^t$ .

It is required to find the interest rate for the investment.

Since, the function can be re-written as,

$y=12(1.18)^t$

i.e. $y=12(1+0.18)^t$

So, on comparing with the formula for compound interest i.e. $A=P(1+r)^t$ , where 'r' is the interest rate.

We have that,

The interest rate for the given investment is 0.18 i.e. 18%.
