What is the length of the hypotenuse of the right triangle shown below? If necessary, round your answer to the nearest hundredth

It is ten units, as the two sides are of 6 and 8 so you must square them both, add them together (which gives you 100) and then square root that, which gives you 10

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%.

A clipboard cost $2.23.It cost $0.58 more than a notebook.Lisa bought two clipboards and one notebook.She paid with a ten dollar

Katen [24]

First you'd subtract .58 from 2.23 to get the price of the notebook.

2.23 - .58 = 1.65

(2.23×2)+1.65= 6.11

Now subtract 6.11 from ten to figure out the change amount.

10 - 6.11 = 3.89
