Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 cm. What is the distance the hula hoop rol
lidiya [134]

Answer:

Distance covered by hula hoop rolls in 4 full rotations is 880 cm .

Step-by-step explanation:

Formula

Perimeter\ of\ a\ circle = 2\pi r

Where r is the radius of the circle.

As given

Allison is rolling her hula hoop on the playground.

The radius of her hula hoop is 35 cm.

r = 35 cm

\pi = \frac{22}{7}

Putting the value in the formula

Perimeter\ of\ a\ hula hoop = 2\times \frac{22}{7} \times 35

                                             = 220 cm

As given

The hula hoop rolls in 4 full rotations.

Distance covered by hula hoop rolls in 4 full rotations =  220 × 4

                                                                                          = 880 cm

Therefore the Distance covered by hula hoop rolls in 4 full rotations is 880 cm .

What are the zeros of the function f(x)=x2−5x−24 ?
scZoUnD [109]
Factor the equation:
x^{2} -5x-24 = (x+3)(x-8)

set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3

x-8 = 0
x = 8

64+16x^2-72x+81=289 I don’t understand
7nadin3 [17]

Answer:

x = 6 or x = -3/2

Step-by-step explanation:

Solve for x:

16 x^2 - 72 x + 145 = 289

Hint: | Write the quadratic equation in standard form.

Divide both sides by 16:

x^2 - (9 x)/2 + 145/16 = 289/16

Hint: | Solve the quadratic equation by completing the square.

Subtract 145/16 from both sides:

x^2 - (9 x)/2 = 9

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 81/16 to both sides:

x^2 - (9 x)/2 + 81/16 = 225/16

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 9/4)^2 = 225/16

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 9/4 = 15/4 or x - 9/4 = -15/4

Hint: | Look at the first equation: Solve for x.

Add 9/4 to both sides:

x = 6 or x - 9/4 = -15/4

Hint: | Look at the second equation: Solve for x.

Add 9/4 to both sides:

Answer:  x = 6 or x = -3/2
