The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?

Answers

Answer 1

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Answer 2

So everyone here in Mrs. Futch?

Find the slope of the line on the graph below

Answers

Answer:

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

The slope is [tex]\frac{6}{5}[/tex] because rise/run. You rise up on the graph 6 units, and run 5 units to the right (if the graph went to the left), then your slope would be negative.

Another way to double check this is using the slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex].

(-3, -3) is x1, y1. & (2, 3) is x2, y2.

So, plugging that into the formula, we get:

[tex]\frac{3-(-3)}{2-(-3)}[/tex] =  [tex]\frac{6}{5}[/tex].

Hope that this helped. Have a good day! ☺

Find the standard form of the equation for the conic section represented by x^2 + 10x + 6y = 47.

Answers

Answer:

The standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

Step-by-step explanation:

We know that:

[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.

Given the equation

[tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex]

Rewriting the equation in the standard form

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

Thus,

The vertex (h, k) = (-5, 12)

Please also check the attached graph.

Therefore, the standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:

[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.

Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800

In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

I think it is 72%

Step-by-step explanation:

Answer:

A. 12%

Step-by-step explanation:

I counted the number of dots in all, and the number of dots in the columns 7 - 8.

There are 25 dots in allThere are 3 dots in columns 7 - 8.

This means that 3/25 of the students in the class have 7 - 8 people in their houses.

Now let's convert the fraction into a decimal, which we'll then convert into a percent.

Let's multiply the numerator and denominator of 3/25 by 4.

We get 12/100!

12/100 as a decimal is 0.12

0.12 as a percent is 12%

Is there a letter which has 12% as an option? Yes, there is! It's A.

The sale price of an item is $330 after a 25% discount. What was the original price of the item?

Answers

Answer:

The original price of the item is $440.

Step-by-step explanation:

If you have a discount for 25% and the resulting price is 330, then 330 is 75% of the original price.

Because of the way my brain works, my first thought was that if $330 is 75% of the original price then, 1/3 of 330 would be 25% of the original price. So, I multiplied 330 by 1/3 and got 110. Then I added 110 and 330 to get 440, the original price.

Original price is 440 I think

What is a number line?

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

In comparison 1/3 to where would 3/9 be located on a number line

As we know, a number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

1/3 = 0.333

3/9 = 1/3 = 0.333

If we plot the above fractions on a number line we will see these two fractions are on the same point.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Thus, in comparison to 1/3 to 3/9, both numbers are located at the same point on a number line.

How many male dogs are in the two parts of the kennel?

Answers

Answer:

39

Step-by-step explanation:

The computation of the number of male dogs in the two parts of the kennel is shown below:

In one part, the male dogs are

= 24 × 5 ÷ 8

= 15

In the another part, the male dogs are

= 30 × 4 ÷ 5

= 24

So, the total male dogs is

= 15 + 24
