Bestie i would say it’s A because you multiply and you don’t have the other surface areas hope this helps <3

A certain bag of potting soil is 1/4 peat moss, and the rest is dirt. What part is dirt?

Troyanec [42]

Answer:

$D = 1 - \frac{1}{4}$

$D = \frac{3}{4}$

Step-by-step explanation:

Given:

1 bag of potting soil

$Peat Moss = \frac{1}{4}$

Required

What part is dirt?

The whole bag of potting soil is represented as 1;

Let P represent Peat Moss and D represented Dirt; Such that

$P + D = 1$

Subtract P from both sides

$P - P + D = 1 - P$

$D = 1 - P$

Substitute $\frac{1}{4}$ for P

$D = 1 - \frac{1}{4}$

Take LCM

$D = \frac{4-1}{4}$

$D = \frac{3}{4}$

Hence,  $1 - \frac{1}{4}$  or  $\frac{3}{4}$  of the potting soil is Dirt

What is the range of f(x)= -3^x+4

V125BC [204]

Answer:

A. The set of all real numbers less than 4

Step-by-step explanation:

The range of the parent function $y=3^x$ is $y\in (0,\infty)$

The graph of the function $y=-3^x$ is reflected across the x-axis graph of the parent function, so the range of the function $y=-3^x$ is $(-\infty,0)$

The graph of the function $y=-3^x+4$ is translated 4 units up graph of the function $y=-3^x$ , so the range of the function $y=-3^x+4$ is $(-\infty,4)$ or the set of all real numbers less than 4.
