Answer:
-7 & 5
Step-by-step explanation:
Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.
Standard form:
5,098,000
Scientific notation.
1) only 1 digit should be before the decimal point.
5.098000
2) only non-zero number must be part of the coefficient. the rest are included in the base of 10.
5.098 x 10^6 Choice D.
Exponent is the number of times the decimal moved from its original placement to its place after the 1st digit.
Answer:
3
Step-by-step explanation:
(6,-5)(9,r)
(r - (-5) / (9 - 6) = -4
(r + 5) / 3 = -4
r + 5 = -4 * 3
r + 5 = -12
r = -12 - 5
r = - 17 <===
