N=1→an=a1 (first term)=16 (on the graph for n=1)→First term = 16
n=2→an=a2 (second term) = 4 (on the graph for n=2)→Second term = 4

ratio=(Second term)/(First term)=a2/a1=4/16
Simplifying the fraction dividing the numerator (4) by 4 and the denominator (16) by 4:
ratio=(4/4)/(16/4)→ratio=1/4

Answer: Option A. First term = 16, ratio = 1/4

Answer:

The last answer choice is correct, I am pretty sure.

Just go on the calculator (like Desmos) and just use the decimals to determine which one is true.

A circular cloud of poison gas from a factory explosion is expanding so that t hours after the explosion the radius of the cloud

diamong [38]

Answer:

6000π m²/h

Step-by-step explanation:

Area of the circular cloud =πr²----------------------------------------- (1)

Radius as a function of time = R(t)=50+20t------------------------ (2)

dA/dt = (dA/dr) x (dr/dt)-----------------------------------------------------(3)

dA/dr = 2πr

dr/dt = 20

After 5 hours, the radius of the cloud will be :

R(5)=50+20(5)

= 150 meters

Substituting into (3)

dA/dt = 2π(150) x 20

= 6000π m²/h

Identify the zeros of the polynomial function .

Komok [63]

Step-by-step explanation:

To start, every term has an

in common, so we can factor that out. Doing this, we get

(

−

)

What I have in blue can be factored by a thought experiment. What two numbers have a sum of

and a product of

−

After some trial and error, we arrive at

−

and

. Thus, this business can be factored as

(

−

)

(

)

We can leverage the zero product property here, setting all three terms equal to zero. As our zeroes, we get

, and

Melissa put her cat, Herman, on a diet and kept track of his weight. At the end of 4 weeks, she recorded Herman's weight change

Sergio [31]

The cats weight change each week is $-1\frac{1}{8}$ ounces

<h3><u>Solution:</u></h3>

Given that, Melissa put her cat, Herman, on a diet and kept track of his weight.

At the end of 4 weeks, she recorded Herman's weight change as $-4\frac{1}{2}$ ounces.

She noticed that he had lost the same amount of weight each week.

We have to find what is Herman's weight change each week of the diet?

Now, let the weight lost per week be n ounces.

Then, in total he lost 4n ounces in 4 weeks

And we are given that, lost wait is $-4\frac{1}{2}$ ounces

$\begin{array}{l}{4 n=-(4 \frac{1}{2}) \text { ounces }} \\\\ {4 n=-(\frac{4 \times 2+1}{2})} \\\\ {4 n=-(\frac{9}{2})} \\\\ {n=-(\frac{9}{8})=-(\frac{8+1}{8})=-1 \frac{1}{8} \text { ounces }}\end{array}$

Here negative sign indicates cat is losing weight

Hence, the cats weight change each week is $-1\frac{1}{8}$ ounces
