I think you would divide each by 2 and get 1 over 1 which would be 1 squared over 1 (negative) cubed

Hope this helps!

The expression below represents the number of bacteria in a petri dish after t hours. Interpret the meaning of the expression.
konstantin123 [22]

The answer is B) The initial number of bacteria is 57, and the growth rate is 31% per hour.


The expression shown is an <em>exponential expression</em>.  An exponential expression usually takes the form ab^{x}, as this one does.  A represents the <em>initial value</em>, in this case-the initial number of bacteria.  B represents the <em>growth rate</em>.  When it is an increasing growth rate, it will begin with 1, because it will have everything it had before, plus the percent increase, the decimal portion.  In this case, a=57, and b=0.31.


Hope this makes sense!

What is the length of the shadow cast by a 12-foot lamp post when the angle of elevation of the sun is 60º? (to the nearest tent
elena-s [515]

Answer:

6.9 foot.

Step-by-step explanation:

Given: Length of lamp post= 12-foot.

           The angle of elevation of the sun is 60°.

∴ The length of Lamp post, which is opposite is 12-foot.

  Now, finding the length of shadow cast by foot lamp.

Length of shadow is adjacent.

∴ We know the formula for Tan\theta= \frac{Opposite}{adjacent}

Next, putting the value in the formula.

⇒ Tan 60° = \frac{12}{adjacent}

Cross multiplying both side and using the value of Tan 60°

∴ Adjacent= \frac{12}{\sqrt{3} } = 6.92 ≅ 6.9 (nearest tenth value)

6.9 is the length of shadow cast by a 12-foot lamp post.

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}

Now that you have your fraction, multiply by 400:

\frac{33}{100} \times 400 = \frac{13200}{100} \rightarrow 132

ANSWER = 132
