Answer is C here is why hope. This helps
Answer:
Step-by-step explanation:
J is a tangent to the circle and it is at right angle,
So applying Pythagorean theorem
HK² = KJ² + HJ²
HK² = 8²+ 15²
HK² = 64 + 225
HK² = 289
HK = √289
HK = 17 mi
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
Answer:
Step-by-step explanation:
The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under
We can solve it further for F as
Dividing both sides by 5 we get
Now substituting values of C in this equation will give us the corresponding values of F
Ex : C=1
Hence 1 degree Celsius is 
degree Fahrenheit
Answer:
-1
i do not remember how to solve this but i just answered a question that had this problem in it on my algebra test and that is the right answer
