2 answers:

8 0

Y=24
First Add 5 to both sides.
y/3 =3+5
Then simplify 3+5 to 8
Multiply both sides by 3
Simplify 8X3to 24 to get your anwser

A baseball is thrown upward and its height after t seconds can be described by formula h(t)=−16t2+50t+5. Find the maximum height

asambeis [7]

h(t) = -16t² + 50t + 5

The maximum height is the y vertex of this parabola.

Vertex = (-b/2a, -Δ/4a)

The y vertex is -Δ/4a

So,

The maxium height is -Δ/4a

Δ = b² - 4.a.c

Δ = 50² - 4.(-16).5

Δ = 2500 + 320

Δ = 2820

H = -2820/4.(-16)

H = -2820/-64

H = 2820/64

H = 44.0625

So, the maxium height the ball will reach is 44.0625

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the

Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201$

0.1201 = 12.01% probability that Alysha will win the bet.

Maurinko [17]

Answer:

18x + 6 = 6(3x + 1)

2x + 4= 2(x + 2)

Explanation:

For 2x +4:

group the common factor

2x + 4

and you'll get 2(x + 2)

For 18x + 6:

You'll do the same thing

18x + 6

and you'll get

6(3x + 1)

later reflected parallelogram abcd across the y-axis. if angle a is 115° and angle b is 65°, what is the degree measurement of a

GaryK [48]

A reflection will not change the measurement of the angle.
Angle a will still be 115 degrees.

Find the area of the shaded sector. Leave your answer in terms of π.

kozerog [31]

Answer:

18π ft^2

Step-by-step explanation:

The area of the circle is

pi *r^2

pi * 12^2

144pi

The part that is shaded is 45 degrees

An entire circle is 360 degrees

The fraction that is shaded is 45/360 = 1/8

Multiply the area by the fraction that is shaded

1/8 * 144 pi

18 pi
