Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour
Answer:
y = -1x + 2
Step-by-step explanation:
- y=mx+b
- going down to the right negative slope
- rise over run so 1/1 makes the slope 1
- negative 1 for the slope
- b is the y-intercept and the line lands on the point (0,2)
Answer: 14.5 in, 14.8in, 15 in, 15.3 in, 15.8 in,
Answer:
B. 3
Step-by-step explanation:
We can use secant theorem.
AX × BX = EX × DX
AX = 7 + 2 = 9
9 × 2 = (3 + x) × 3
18 = 9 + 3x
18 - 9 = 3x
9 = 3x
x = 9/3 = 3
