My best guess is the first option g= W+5 (5 more than g) and g=w-2 (also less than g).
Hope it helps :)
So we want to know the volume of a sphere in terms of pi if we know the area of the sphere is equal to A=9pi. So the area of the sphere is A=4*pi*r^2 and the volume V=(4/3)*pi*r^3. We can get the radius from the area: 9pi=4*pi*r^2 and we see the pi cancels out: 9=4*r^2. We divide by 4 and take the square root: r=sqrt(9/4)=3/2. So r=3/2 and we can input it into volume V.
V=(4/3)*(3/2)^3*pi=(4/3)*(27/8)*pi=(9/4)*pi.
So the volume of the sphere is V=(9/4)*pi cubic feet.
88 % students of the class hand in their projects on time
<em><u>Solution:</u></em>
Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time
Total number students = 25
Students hand in their projects on time = 22
<em><u>To find: percent of the class hand in their projects on time</u></em>
Substituting the values, we get
Thus 88 % students of the class hand in their projects on time
Answer:
B
Step-by-step explanation:
Using the trig. identity
cos x =
Given
secx = - , then
cos x = - × = - = - , thus
x = (- ) = → B
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
