Answer:
- 12
Step-by-step explanation:
To evaluate (g ○ h)(1), evaluate h(1) then substitute this result into g(x)
h(1) = 3(1) + 4 = 3 + 4 = 7, then
g(7) = - 2(7) + 2 = - 14 + 2 = - 12
Answer:
arcBC = 140degrees
Step-by-step explanation:
From the given digaram;
Angle at the center is twice angle at the circumference
Hence;
m<CAB = 2(m<CDB)
m<CAB = 2 * 35
m<CAB = 70degrees
Also;
m<CAB = 1/2 arcBC
70 = 1/2arcBC
arcBC = 70*2
arcBC = 140degrees
Answer: He ran 8 miles on week 5, which was an improvement of 6.4 miles compared to the 1.6 miles he ran on the first week,
Step-by-step explanation:
