The number of significant figures of the number 70.00 is four. If there is a decimal point in the number, start counting from the left. The first significant figure is 7. All the zeroes that follow this number are also significant. There are three zeroes making the number of significant figures four. The answer is letter c.
Answer:x f(x) = 2.5x − 10.5 g(x) = 64(0.5x)
2 f(2) = 2.5(2) - 10.5 g(2) = 64(0.5*2)
f(2) = 5 - 10.5 g(2) = 64(1)
f(2) = -5.5 g(2) = 64
3 f(3) = 2.5(3) - 10.5 g(3) = 64(0.5*3)
f(3) = 7.5 - 10.5 g(3) = 64(1.5)
f(3) = -3 g(3) = 96
4 f(4) = 2.5(4) - 10.5 g(4) = 64(0.5*4)
f(4) = 10 - 10.5 g(4) = 64(2)
f(4) = -0.5 g(4) = 128
5 f(5) = 2.5(5) - 10.5 g(5) = 64(0.5*5)
f(5) = 12.5 - 10.5 g(5) = 64(2.5)
f(5) = 2 g(5) = 160
6 f(6) = 2.5(6) - 10.5 g(6) = 64(0.5*6)
f(6) = 15 - 10.5 g(6) = 64(3)
f(6) = 4.5 g(6) = 192
Answer:
21π m, or ≈ 65.94 m
Step-by-step explanation:
Remember that π is the ratio between a circle's circumference and its diameter, or, in equation form:
where c is the circumference and d is the diameter. If we want to find the <em>circumference</em>, we can just multiply that equation by d on both sides to get
Here, our d = 21 m, so our circumference would be
m, or approximately 21(3.14) = 65.94 m
Answer:
the second ones
Step-by-step explanation:
Try shutting of things that could distract you. (Television, phone, computer etc.)
Get away from noise; go somewhere quiet.
