have a nice day!!

I will do it in a way that can solve all these kinds of problem.

Of course, you can just substitute every possible answer in and see which one has the highest y value.

BUT I'm going to do this question by completing the square.

First organize the equation by decreasing degrees.

y=-16t^2+32t

Now factor out a -16 to make the x variable have no coefficient.

y=-16(t^2-2t)

Now complete the square.

y=-16(t-1)^2+16

By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.

The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8

Answer:

-2.8 is correct

Answer:

[tex]x\geq -6[/tex]

Step-by-step explanation:

The domain of a function is all of the values that [tex]x[/tex] can be under that specific function. In this case, we're asking what values of [tex]x[/tex] allow [tex]\sqrt{\frac{1}{3} x+2}[/tex] to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to [tex]0[/tex], because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for [tex]x[/tex]:

[tex]\frac{1}{3}x+2\geq 0[/tex]

Solving this inequality, we get:

[tex]\frac{1}{3}x+2\geq 0[/tex]

[tex]\frac{1}{3}x\geq -2[/tex] (Subtract [tex]2[/tex] from both sides of the inequality to isolate [tex]x[/tex])

[tex]x\geq -6[/tex] (Multiply both sides of the inequality by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)

Answer:

4.76%

Step-by-step explanation:

A jar will hold 252 grams of powder

The label shows that its contains 240 grams

Therefore the percent error can be calculated as follows

= 240-252/252 × 100

= -12/252 × 100

= 0.0476 × 100

= 4.76%

Hence the percent error is 4.76%

Answer:

2144.66 cubic inches

Step-by-step explanation:

The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.

What is the closest value of water in the Fishbowl in cubic inches?

From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.

This means we are to find the volume.

The volume of a sphere is given as:

4/3πr³

We are given Diameter of the fish bowl = 16 inches

Radius = Diameter/2 = 16 inches/2

= 8 inches

Hence,

Volume of the sphere (Volume of water) = 4/3 × π × 8³

= 2144.66 cubic inches

Answer:

He missed 3 questions (which is a score of 22/25 that equals 88%)

Step-by-step explanation:

This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.

So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.

Answer:

4

Step-by-step explanation:

The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.

Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.

Solving that equation will give you b=-7

That means the y-intercept is -7.

The equation would then be y=4x-7

t

Answer:

This illustrates a right triangle.

Given:

a(height) = 2457 ft.

∠A = 22°23' ; which is the elevation and reflects the a(height)

Find:

b(base)

Solution:

Using the law of cosine, specifically tan∠ = opposite side÷adjacent side

By analysis, tan∠A = a÷b

Since we are finding b, the formula will be derived into:

b = a÷tan∠A

Find b(base):

b = 2457 ft. ÷ tan22°23' ; substituting the numbers

b ≈ 5,966.05 ft. ; Final Answer

Step-by-step explanation:

Answer:What happens when the y-intercept is greater than 1?: more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept. This function never crosses the y-axis because, since you can't divide by zero, it is undefined at x=0.

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Nothing special happens when the y-intercept is above or below the value of 1. The y-intercept is where the function's graph intersects the y-axis.

When the y-intercept is greater than 1, the graph intersects the y-axis above the point (0, 1).

When the y-intercept is less than 1, the graph intersects the y-axis below the point (0, 1).

The meaning of the y-intercept will depend on what the graph is modeling. No information about that is provided here.

Answer:

1,050 years

Step-by-step explanation:

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

"The number of boys is 45 the number of girls,"

or to say,

"The ratio of the number of boys to the number of girls is 45:1."

This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.

Answer: B

Step-by-step explanation:

Applying limits, it is found that the end behavior of the graph is:

B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].

The function is:

[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]

To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:

[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]

Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]

[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]

Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]

Hence, option B is correct.
