The x-intercepts of this function are: (-2,0), (-3,0), and(5,0)

Answer:

x intercepts are (-2,0) (-3,0) and (5,0)

Step-by-step explanation:

Given polynomial function is (x+2)(x+3)(x-5)

We need to find out x intercepts

To find x intercepts we set the polynomial function =0 and solve for x

(x+2)(x+3)(x-5) =0

We apply zero factor property. Set all the factors =0  and solve for x

x+2=0  , so x=-2

x+3 =0 , so x=-3

x-5=0, so x= 5

Now we write all the x  intercepts in ordered form (x,0)

(-2,0) (-3,0) and (5,0)

The box plots show the weights, in pounds, of the dogs in two different animal shelters.
vovikov84 [41]

Answer:

The range in shelter A is 22, and the range in shelter B is 18.

Step-by-step explanation:

Okay so basically, the range is the difference between the smallest number and the greatest number.

The smallest weight for shelter a is 8. The largest weight is 30.

30-8= 22.

Same thing for the other shelter. The smallest weight is 10, and the largest weight is 28. 28-10= 18.

Write the inverse variation function given that y varies inversely with x, and y = 0.25 when x = 8.
storchak [24]

Answer:

Step-by-step explanation:

If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.

If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes

y = k/x

When y = 0.25, x = 8

Substituting into the expression above, it becomes

0.25 = k/8

k = 0.25 × 8

k = 2

The inverse variation function is

y = 2/x

Which linear inequality is shown on the graph?
AlekseyPX
Answer: choice C) x-y <= 2

======================================

Explanation:

The two points (0,-2) and (2,0) are on the boundary line. The boundary line equation is y = x-2. We find this equation through the use of the slope formula to find that m = 1. The y intercept is -2 so b = -2. Therefore, y = mx+b turns into y = 1x+(-2) which simplifies to y = x-2

The equation y = x-2 can be arranged to get x-y = 2 (subtract y from both sides; add 2 to both sides)

So the answer is either x-y <= 2 OR it is x-y >= 2

The question is: which inequality has the test point (0,0) in it? We pick on the origin since 0 is the easiest number to work with.

Plug (x,y) = (0,0) into the equation for choice C
x-y <= 2
0-0 <= 2
0 <= 2
which is true. So choice C is the answer.

Choice D can be ruled out since...
x-y >= 2
0-0 >= 2
0 >= 2
which is false: 0 is not larger or equal to 2

Find the number of years it would take for $1200 to earn simple interest of $324 at an annual interest rate of 6% per year
topjm [15]

ANSWER

It would take 45 good years

<u>EXPLANATION</u>

We calculate simple interest using the formula,

I=\frac{P\times T\times R}{100}


From the question,


I=324 dollars


R=6%

and

P=120 dollars


We substitute into the above formula

324=\frac{120\times T\times 6}{100}


324=\frac{720\times T}{100}

324\times100=720\times T


\frac{324\times100}{720}=T



\frac{324\times10}{72}=T


45=T


Therefore it would take 45 years.
