a ferris wheel has a radius of 24 feet and travels 5.6 feet every second. at what constant angular speed does the ferris wheel rotate at (in radians per second)?

Answer:

a = 32.3 m/s^2

F = 64.6 N

Step-by-step explanation:

a = v^2 / r

a = 10^2 / 3.1

a = 32.3 m/s^2

F = ma

F = 2 * 32.3

F = 64.6 N

The number of 3point shot made by Marques is 2 and the number of free throws he made is 6

Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations. This implies that the simultaneous equations have a common solution.

If the number of 3points made is x and the number of free throw is y, then

x+y= 8 equation 1

the total points made will be

3x+y= 12 equation 2

subtracting equation 1 from 2

2x = 4

x= 4/2= 2

substitute 2 for x in equation 1

2+y= 8

y= 8-2= 6

therefore the number of 3points shot and free throw made are 2 and 6 respectively.

The interval for the inequality is (5, ∞].

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

-11m <= -55

Now, solving the inequality

-11m ≤ -55

Divide both side by 11

-11m/ 11 ≤ -55/ 11

-m ≤ -5

m≥ 5

Hence, the interval for the inequality is (5, ∞]

The probability that the average fracture strength of 100 randomly selected pieces of this glass exceeds 14.3 is 0.16%.

The normal distribution is a type of probability function that describes how a variable's values are distributed. Since the majority of the observations cluster around the curve's middle peak, it is symmetric. In both directions, the probability for values of the distribution that are far from the mean.

Given that the fracture strength of tempered glass averages 14.1 (measured in thousands of pounds per square inch) and has standard deviation 2.

We have to determine what is the probability that the average fracture strength of 100 randomly selected pieces of this glass exceeds 14.3?

We that μ = 14.1 σ = 2 n = 100 δ = 2/√100 = 0.2

This probability is 1 subtracted by the p-value of Z when X = 14.3. So

Z = (x-μ)/σ

By the Central Limit Theorem

Z = (x-μ)/δ

Z = (14.3 – 14.1)/0.2

Z = 0.2/0.2

Z = 1

Z =1 has a p-value is 0.8413

= 1 - 0.8413 = 0.1587

Therefore 0.16% is the probability that the average fracture strength of 100 randomly selected pieces of this glass exceeds 14.3.

Answer:

Step-by-step explanation:

Amber coaches both sports for 7 hours each day

v = volleyball hours

s = soccerball hours

7 hours in total, in which soccerball is 1 hour more than volleyball:

v + s = 7

s = v + 1

plug in v + 1 for s

v + s = 7

v + (v + 1) = 7

simplify

v + v + 1 = 7

2v + 1 = 7

2v + 1 (-1) = 7 (-1)

2v = 6

2v/2 = 6/2

v = 6/2

v = 3

Plug in 3 for v for one of the equations.

s = v + 1

s = (3) + 1

s = 4

Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours becuase 4+3 equals 7

Answer: 5.4 inches

Step-by-step explanation:

The area of a triangle is the base x height/2.

The red is telling you the triangle is 2.7 inches tall, and the black is telling you that the base is 4 inches.

That means the answer is 4 * 2.7/2 = 5.4

The equation of the parabola that has its x-intercepts at (-1.6, 0) and (-3.2, 0) and its y-intercept at (0, 25.6) is  5x² + 8x - 25.6

The x intercept refers to the value of x when y = 0 this otherwise known as the roots of the polynomial equation.

The intercept form of parabolic equation is

y = a(x - p)(x - q)

where

p and q are roots

a = constant

writing the equation at (-1.6, 0), (-3.2, 0)

y  = a( x + 1.6 ) ( x + 3.2 )

passing through point (0, 25.6)

25.6  = a( 0 + 1.6 ) ( 0 + 3.2 )

25.6 = 5.12a

a = 5

substituting into the equating gives

y = a(x - p)(x - q)

y = 5( x + 1.6 ) ( x + 3.2 )

expanding the equation gives

= 5(x² + 3.2x - 1.6x - 5.12)

= 5(x² + 1.6x - 5.12)

= 5x² + 8x - 25.6

The measure of angle E is 121 degrees

The length of the side AB = The length of the side DE

The length of the side BC = The length of the side EF

The length of the side AC = The length of the side DF

The three sides of the triangle ABC is equal to the three sides of the triangle DEF.

Therefore the triangle ABC and triangle DEF is congruent

Therefore,

Angle B = Angle E

96 + y = 6y - 29

6y -y = 96 + 29

5y = 125

y = 125 / 5

y = 25
