5 0

Given:

The exponential equations in the options.

To find:

The equation which represents exponential decay.

Solution:

The general exponential equation is

y=ab^x

where, a is initial value and b is growth rate.

If b<1, then it is an equation of exponential decay.

If b>1, then it is an equation of exponential growth.

In option A, b=31>1, i.e., exponential growth.

In option B, b=3.1>1, i.e., exponential growth.

In option C, b=0.13<1, i.e., exponential decay.

In option D, b=1.03>1, i.e., exponential growth.

Only y=10(0.13)^x represents exponential decay.

Therefore, the correct option is C.

marshall27 [118]

Answer:

(a)6 feet

(b)24 sections

Step-by-step explanation:

(a)We are required to find the length of the Giant Sub.

If each section is 1/3 of a foot long and there are 18 equal parts.

Length of the Giant Sub =

Length per Section X Number of Sections

= 1/3 X 18 = 6 feet

(b)If each section is 1/4 of a feet long

Length of the Giant Sub =

Length per Section X Number of Sections

6= 1/4 X Number of Sections

Number of Sections =6 X 4 =24 sections

3+3/4x= 7/10 do not use decimals in your answer
murzikaleks [220]

Answer:

x = -\frac{45}{15}

Step-by-step explanation:

We have the equation: 3 + \frac{3}{4} x = \frac{7}{10}

Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign

\frac{3}{4} x = \frac{7}{10} - 3

Calculate the difference.

\frac{3}{4} x = -\frac{23}{10}

Divide.

(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)

So, we get the equation -\frac{23}{10} x \frac{4}{3} which is -\frac{45}{15} .

I hope this helps!
