75 multiply by 5 and 4 multiply by 45
375+180=555
we know that
1) <u>convert miles per hour to feet per hour</u>
<u>2) convert feet per hour to feet per second</u>
Round to the nearest whole number------->
therefore
<u>the answer is</u>
We know that tanθ = sinθ/cosθ
For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.
Hope I helped :)
Solve for k:
X^2 + (y - k)^2 = 21
Subtract X^2 from both sides:
(y - k)^2 = 21 - X^2
Take the square root of both sides:
y - k = sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
-k = sqrt(21 - X^2) - y or y - k = -sqrt(21 - X^2)
Multiply both sides by -1:
k = y - sqrt(21 - X^2) or y - k = -sqrt(21 - X^2)
Subtract y from both sides:
k = y - sqrt(21 - X^2) or -k = -sqrt(21 - X^2) - y
Multiply both sides by -1:
Answer: k = y - sqrt(21 - X^2) or k = sqrt(21 - X^2) + y
