Answer: 78.5
Step-by-step explanation:
Well i said 78.5 to get the radius you have to divide the diameter by 2 to get your answer but you have to make and the area might be 78.5 because thats what we do in my grade which is 7th
Answer: Factors (x + 2)(x + 7)
Solutions x = -2, x = -7
<u>Step-by-step explanation:</u>
h(x) = x² + 9x + 14
∧
1 + 14 = 15
2 + 7 = 9 ⇒ This sum is the coefficient of the middle term!
(x + 2) (x + 7)
To get the solutions, set each factor equal to zero and solve.
x + 2 = 0 x + 7 = 0
<u> -2 </u> <u> -2 </u> <u> -7 </u> <u>-7 </u>
x = -2 x = -7
Answer:
Option (3)
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
= ![192+2\pi (\frac{35}{2})](https://tex.z-dn.net/?f=192%2B2%5Cpi%20%28%5Cfrac%7B35%7D%7B2%7D%29)
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
= 1207.6 m
Option (3) will be the correct option.
