Step-by-step explanation:
1/sin^2A -cos^2A/sin^2 A. ~tan = sin/cos
(1-cos^2)/sin^2A. ~ take lcm
sin^2A/sin^ A. ~ 1-cos^2A = sin^2A

the average rate of change is 4
Step-by-step explanation:
I'm going to assume you mean:
13 * (3/4) + x = 7 * (1/4)
Let's go ahead and simplify the right side.
7 * (1/4) = 1.75
So now we have:
13 * (3/4) + x = 1.75
Now let's take care of the right side. Multiplication before addition.
13 * (3/4) = 9.75
9.75 + x = 1.75
To isolate x, we subtract 9.75 from both sides.
9.75 - 9.75 + x = 1.75 - 9.75
x = -8

Answer:
1.8° F
Step-by-step explanation:
Given that:
Mehwish's temperature at 9:00 = 97.2°F
Mehwish's temperature at 4:00 = 99°F
The degree rise in Mehwish's temperature is :
(Mehwish's temperature at 4:00 - Mehwish's temperature at 9:00)
(99°F - 97.2°F)
= 1.8°F
Therefore. The number of degree rise in Mehwish's temperature is 1.8°F
