Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
Answer:
1800
Step-by-step explanation:
24 divided by 4 equals 6. So 6 multiplied by 300 equals 1800.
To be honest the answer is going to be the same.
Well because first of all their is a X in one number instead of the other. Second of all we don't know how much the X equals. And ya that's all.
Answer:
y-intercept: 0
slope:120/7
Step-by-step explanation:
Answer:
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
a: 42
b: 135 km/h
Step-by-step explanation:
For part A, you are given the adjacent and opposite side lengths so you need to use the tangent formula. On the calculator, it is tan^-1 (90/100)
For part B, I used the pythagorean theorem and did 100^2+90^2= 18100 and then took the square root of that to get 135.
