In this situation I would use cosine to find m∠G.
Cosine = Adjacent side ÷ Hypotenuse
RG being the adjacent side and TG being the hypotenuse, you would set up the equation like this
cos(g) = 8/17
then solve
cos(g) = 0.47058
simplify
g = cos^-1(0.47058)
and you get
m∠G = 61.9°
So your answer would be 62°
4.5 m = 4.5 x 1 m
= 4.5 x 100 cm
= 450 cm

Answer:
1. t - statistics = 1.581
2. We accept null hypothesis that the mean number of calls is less than or equal to, i.e., ≤, 41 per week.
Step-by-step explanation:
Significance level = 0.025
Sample size = 38
Sample mean = 42
Standard deviation = 3.9
Claimed mean = 41
1. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
t - statistics = 1.581
2. What is your decision regarding null hypothesis? The mean number of calls is than 41 per week.
Degree of freedom = Sample size - 1 = 38 - 1 = 37
At 0.025 significance level,
t-table = 2.021
Since t - statistics (i.e. 1.581) is less than t-table (2.021), we accept null hypothesis that the mean number of calls is less than or equal to, i.e., ≤, 41 per week.
Answer:
steps below
Step-by-step explanation:
This is a contradictory proof of sophistry
f(x+4) = f(x)+f(4) ...(1) when x=0
f(x+4) = f(0+4) = f(4) = f(x) + f(4)
f(x) = f(4)-f(4) = 0
From (1): f(x) = f(x+4) - f(4)
x=-4 <u> f(-4)</u> = f(-4+4) - f(4) = f(0) - f(4) = <u>-f(4)</u> ...(2)
From (1): f(x+4) = f(x)+f(4)
x=4 f(4+4) = <u>f(8)</u> = f(4) + f(4) = 2f(4) = <u>-2f(-4)</u> from (2) ... (3)
f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0
