Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).

DochEvi [55]

Let $y=ab^x,$ as described in the problem statement. Plugging in $x=2$ and $x=5$ gives us the equations $18=ab^2$ and $60.75=ab^5.$ Since $a,b$ are nonzero, we divide the second equation by the first to get $\frac{27}{8}=b^3,$ which means that $b=\frac{3}{2},$ after taking the cube root. Plugging this value for $b$ into the first equation, we now have $18=a(3/2)^2=\frac{9a}{4}.$ Solving gives $a=8,$ and our desired exponential equation is $\boxed{y=8\left(\frac{3}{2}\right)^x}.$

A car traveling on the taconic parkway travels 84 mike in two hours what is the cars speed (a special type of rate) in miles per

avanturin [10]

we know that

the speed's formula is equal to

$speed=distance/time$

in this problem we have

$distance=84\ miles\\time=2\ hours$

Substitute the values in the formula

$speed=84/2$

$speed=42\frac{miles}{hour}$

therefore

<u>the answer is</u>

$42\frac{miles}{hour}$

In 1994, the General Social Survey had a question that asked its participants (that currently smoked) if they had ever tried to

Roman55 [17]

Answer:

0.8239 is the population proportion of participants that tried quitting smoking.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 142

Participants that tried quitting smoking = 117

Parameter:

A parameter is a numerical value that describes a population.

Population proportion can be calculated as:

$p = \dfrac{x}{n} \\\\p= \dfrac{117}{142} \\\\p= 0.8239$

0.8239 is the population proportion of participants that tried quitting smoking.
