Answer:
B 32
Step-by-step explanation:
sqrt(71*x)
71 is prime
sqrt(71) sqrt(x)
A. 19 prime
B. 32 = 16*2 16 is a perfect square
C. 34 = 2*17 both of which are prime
D. 41 prime
sqrt(71) sqrt(16 *2) = sqrt(71) * sqrt(16) * sqrt(2) = sqrt(71)*4*sqrt(2)
=4sqrt(142)
Answer:
The horse travels 31 feet over an angle of
radians
Step-by-step explanation:
- The formula of the length of an arc is L =
× 2πr, where x is the central angle subtended by this arc and r is the radius of the circle - To change the angle from radian measure to degree measure multiply it by
∵ A carousel horse travels on a circular path
- That means the distance that the horse travels is the length
of an arc of the circular path
∵ The radius of the circular path is 15 feet
∴ r = 15 ft
∵ The horse travel over an angle of
radians
- Let us change it to degree by multiply it by 
∵
×
=
= 120°
- use the formula above to find the distance
∵ d =
× 2πr
∵ x = 120°
∴ d =
× 2π × 15
∴ d = 10π
∴ d = 31.41592654 feet
- Round it to the nearest foot
∴ d = 31 feet
The horse travels 31 feet over an angle of
radians
Answer:
number 5 is 15x
Step-by-step explanation:
what you have to do is just add basically. The ones with exponents you do the usual with those as well. Ignore the X's and when you solve the problem add the x beside the number.
Move the figure 10 units to the right and then rotate it 90º
Answer:
8
Step-by-step explanation:
Since this isosceles triangle has been broken down into two right triangles, and we already know that two sides are the exact same (note that there are 2 x's) that means BD and BC are going to be the exact same length. Since BD is 4, that means BC will be 4, and that means

Hope this helped!
