Answer:

42 in^2

Step-by-step explanation:

The given is a parallelogram and to calculate the area of a parallelogram we multiply its height and base

The height here is given as 6in and base is 7in

7*6 = 42, the area is presented in square units so the answer is 42 in^2

The equation that he can use to find n, the number of gallons of water he should remove is; (3.52)/(22 - n) = 24/100

Let us first find the amount of ammonia in 22 gallons of 16% ammonia solution.

This gives;

Amount = 16% * 22 gal

Amount = 3.52 gal

Now, the amount of ammonia remains the same after the water evaporates, but the total amount of solution will reduce by the amount of water that evaporates.

Amount of ammonia = 3.52 gal

Amount of water that remains = 22 - n

Desired concentration = 24% = 24/100

Thus, the equation is;

(3.52)/(22 - n) = 24/100

Answer:

-6(x-1)^2+9

Step-by-step explanation:

This function is in vertex form, or a(x-h)^2+k. In this equation, h is the horizontal translation, where positive h is right and negative h is left. To translate this function 6 units left, you can subtract 6 from the current h.

6 units left means change in x axis

x is shifted 6 units leftwards

Hence new translation

Considering the hypothesis tested and the p-value of the test, the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

At the null hypothesis, it is tested if there is no difference between the cholesterol levels, that is:

H₀:Hₓ-H

At the alternative hypothesis it is tested if there is a difference, hence:

H₀:Hₓ-H≠0

The p-value is of 0.003 < 0.01, hence we reject the null hypothesis and conclude that there has was a difference, hence the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

Answer:

My best Gues is x=0 and x=6

Step-by-step explanation:

Because The zeroes of a function is where the line is equal to fx=0 which means it is where the line intercepts with the x axis. And the the line is on the x- axis touching 0 and it isn’t touching any negative number so it would have to be positive and would be 6.

zeros are the x inetercepts

Here the x intercepts are

Hence

So

Answer:

1017.36 m²

Step-by-step explanation:

Info:

Diameter: 36m

π: 3.14

---

If the formula for area of circle is: A = πr², and the radius is 18 (half of 36)

Then to find the area, we just multiply π with 18².

18 x 18 = 324.

324 x 3.14 = 1017.36

The area of the circle is 1017.36 m²

Hi Student!

The first step to most problems is to determine the important information that is provided in the given problem statement.  In this problem we can see that we are given a diameter of a circle which is 36 meters.  Another important thing that we can determine is that the question is asking for us to find the area of the circle using 3.14 for π.

Now that we have collected our important information we can move onto the next step which isn't to find the area yet.  First, we need to determine what the radius of our circle is.

Determine the radius

Now, we can finally plug in our values into the area of a circle equation and solve.  The only thing that we need to find the area is the radius which we determined from the previous step.

Plug in the values

Expand the exponent

Multiply the final two numbers

Therefore, the area of a circle with a diameter of 36 meters is 1017.36 meters squared.
