Answer:

x =0

Step-by-step explanation:

4+5e^x+2 =11

Combine like terms

6 + 5e^x =11

Subtract 6 from each side

6-6 + 5e^x =11-6

5 e^x = 5

Divide by 5 on each side

5 e^x /5 = 5/5

e^x = 1

Take the natural log on each side

ln (e^x) = ln(1)

x = ln(1)

x =0

Which statement BEST describes the growth of bacteria modeled by the function f(x)=1.8x

lara [203]

Answer:

Step-by-step explanation:

f(x) = 1.8x is a linear function and does not model the growth of bacteria. Perhaps you meant f(x) = 1.8^x, which is an exponential function whose initial value is 1. Please ensure that you have copied down this problem exactly as it was presented.

What is 33 percent of 400

Eduardwww [97]

<h2>QUESTION</h2>

What is 33% of 400?

<h2>ANSWER AND EXPLANATION</h2>

To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.

<h3>DECIMAL</h3>

To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.

$33 \% \rightarrow 0.33$

Now that you have your decimal, multiply by 400:

$0.33 \times 400 = 132$

ANSWER = 132

<h3>FRACTION</h3>

To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.

$33 \% \rightarrow \frac{33}{100}$
