What are the points for f(x)=3^(x-1)-2

Savatey [412]

Answer: (0, -1 $\frac{2}{3}$ ), (1, -1), (2, 1)

<u>Step-by-step explanation:</u>

Set the exponent equal to zero - <em>that is your anchor point</em>.

Then choose an x-value less than and greater than the anchor point.

$\left\begin{array}{c|c|l}&\underline{\quad x\quad }&\underline{\qquad \qquad f(x)\qquad \qquad \qquad \quad }\\\text{less than anchor}&0&3^{0-1}-2=3^{-1}-2=\frac{1}{3}-2 = -1\frac{2}{3}}\\\\anchor\ point&1&3^{1-1}-2=3^{0}-2=1-2 = -1}\\\\\text{greater than anchor}&2&3^{2-1}-2=3^{1}-2=3-2 = 1}\end{array}\right$

kirill115 [55]

Answer:

If the amount spent on books per month by all her the classmates is leveled, that amount would be $30.

Step-by-step explanation:

The mean is the average amount calculated by finding the sum of a certain group of numbers, then dividing it.

This can be described as "leveling" the amount, since it is the total average.

So, the mean of $30 in this situation means that the average amount that her classmates spend on books is $30.

The correct answer is that If the amount spent on books per month by all her the classmates is leveled, that amount would be $30.

The diameter of a softball is 3.8 inches. Estimate the volume within the softball. Round answers to the nearest whole number and

bekas [8.4K]

Answer:

Volume of softball is 29 cubic inches.

Step-by-step explanation:

Here we are given that the diameter of a softball is 3.8 inches.

To find the volume of the softball, we must consider the volume of a sphere formula, which is given by:

$V=\frac{4}{3}\pi r^{3}$

We also know that radius is half of diameter.

Radius of softball is half of 3.8 which is 1.9 inches.

Plugging this value in the formula, we have

$V=\frac{4}{3}\pi (1.9)^{3}$

Volume = 28.73 cubic inches.

Rounding to the nearest whole number:

Volume of softball will be 29 cubic inches.
