4 0

Midpoint means 1/2 way
separate the x's and the y's find the middle of the x length, middle of the y length
x: 5 - 3 = 2 1/2 of 2 = 1 from either end (3 + 1) or (5-1) = 4
y: 3-(-5) = 8 1/2 of 8 = 4 from either end (3-4) or (-5 +4) = -1

midpoint is therefore (4, -1)

Each of the students at piano recital takes about 8 3/4 minutes to introduce themselves and play 3 songs. There are 9 students p

Tomtit [17]

For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:

$8 \frac {3} {4} = \frac {4 * 8 + 3} {4} = \frac {32 + 3} {4} = \frac {35} {4}$

Thus, each student takes $\frac {35} {4}$ minutes.

If there are 9 students in the recital then we have:

$9 * \frac {35} {4} = \frac {315} {4} = 78.75$ minutes.

Thus, the recital lasts at least 78.75 minutes.

Answer:

The recital lasts at least 78.75 minutes.

Does each function describe exponential growth or decay?

Aleksandr [31]

<h3>Answer: Only first two are exponential growth function and last three functions are exponential decay functions.</h3>

Step-by-step explanation: We need to describe exponential growth or decay for the given functions.

The standard exponential function equation is

$y=a(b)^x$ .

Where a is the initial value and b is the growth factor.

Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.

Let us check them one by one.

$y=(1.008^{1/12}})^{12t}$ => $y=(1.008^})^{1/12\times{12t} }$

=> $y= (1.008)^t$ .

Value of b is 1.008 > 1, therefor it's an exponential growth function.

y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.

All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.
