That's a vertical line, no slope, so no y=something.
Answer: x = -9
1 revolution of a circle = circumference of that circle.
<span>1 revolution of a circle with the diameter of 28 inches = </span><span><span>πd=28π</span><span>πd=28π</span></span><span> inches. Hence, x revolutions per second = </span><span><span>28πx</span><span>28πx</span></span><span> inches per second = </span><span><span>60∗28πx</span><span>60∗28πx</span></span><span> inches </span>per minute.
<span>Given that </span><span><span>60∗28πx=35πn</span><span>60∗28πx=35πn</span></span><span> --> </span><span><span>n=<span><span>60∗28πx</span><span>35π</span></span>=48x</span><span>n=<span><span>60∗28πx</span><span>35π</span></span>=48x</span></span><span>.</span>
Okay, so the formula for a confidence interval is
test statistic +/- (critical value)(standard deviation of statistic
44 +/- (invNorm(area: 0.05, u=0, std:1))(14.5)
44 +/- 23.85
(20.15, 67.85)
hope this helps :)
Tan C = 350 / 500
tan C = 0.7
∠ C = tan^(-1) 0.7
∠ C = 34.99° ≈ 35°
Answer:
The measure of angle C is
A. 35°
Answer + step-by-step explanation:
125
c = a2 + b2 = 75^2 + 100^ 2=125
