In the past, professional baseball was played at the Astrodome in Houston, Texas. The Astrodome has a maximum height of 63.4 m.

Answer:

The correct value of the h function is; h= -9.8t² + 45t + 1

Using the discriminant, no real solution exists and the baseball will not hit the roof

.Step-by-step explanation:

h= -9.8t² + 45t + 1

Astrodome has a maximum height of 63.4 m

find out if the baseball hit at a velocity of 45 m/s will hit the roof, we'll replace h with 63.4m.

Thus;

63.4 = -9.8t² + 45t + 1

Subtract 63.4 from both sides to give;

-9.8t² + 45t + 1 - 63.4 = 0

-9.8t² + 45t - 62.4 = 0

Using quadratic formula, we have;

t = -45 ± √{(45² - (4 * (-9.8) * (-62.4)}

t = -45 ± √(2025 - 2446.08)

t = -45 ± √(-421.08)

The discriminant is -421.08

This value is less than 0.

Thus, no real solution exists and the baseball will not hit the roof.

Min is about to roll a six-sided number cube. What is the experimental probability that she will roll an even number based on he

masya89 [10]

Answer:

Therefore the experimental probability that she will roll an even number is

C ) 0.5

Step-by-step explanation:

Let S be the sample space for the given experiment that to Roll six sided number Cube

∴ S ≡ { 1, 2, 3, 4, 5, 6}

∴ n(S) = 6

Let 'A' be the event of experiment that she will roll an even number

∴ A ≡ { 2, 4, 6 }

∴ n(A) = 3

To Find:

P(A) = ?

Solution:

We know that for any experiment probability is given by

$\textrm{probability of the experiment}=\dfrac{\textrm{number of favourable outcomes}}{\textrm{total number of outcomes}}$

Substituting the values we get

$P(A)=\frac{n(A)}{n(S)} =\frac{3}{6} =\frac{1}{2} =0.5$

Therefore the experimental probability that she will roll an even number is

C ) 0.5

I need help finding X please

Vedmedyk [2.9K]

Hello

This is a right angle as you can see by the small square at the bottom. So this means that it is 90 degrees.

Because we already know part of the 90 degrees, we can do 90-50 degree which leave us with 40 degrees.

So as we look at 8x, it needs to equal 40

- 8x=40 divide both sides by 8

- x=5

Hope this helps!
