For the function y = -10x find the matching y-value when x = 3

Alchen [17]

Answer:

y= -30

Step-by-step explanation:

THis is because you substitue 3 for X and then multiply -10 and 3 and a negative times a positive is a negative so -10 times 3 is -30

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%.

The graph of an exponential function is given. Which of the following is the correct equation of the function?

Effectus [21]

The answer is choice D

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

Explanation:

We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.

The answer is either choice A or choice D

If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625

The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.

Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
