Answer:
They used 3.14 for pi:
Step-by-step explanation:
is the volume of a sphere with radius r.
I think that is the diameter given in the picture.
The radius is half the diameter.
So the radius is 5 since the diameter is 10.
Plug in this gives you:
Answer:
4x²+x+5.
Step-by-step explanation:
5x²+4x+1-(X²+3x-4).
5x²+4x+1-x²-3x+4.
5x²-x²+4x-3x+1+4.
4x²+x+5.
First, find the probability of each event:
1) the probability that the spinner will land on a 7.
Since the spinner is split 4 equal sections and there is only 1 sector with 7, we can say the probability of getting a 7 is 1/4 as there is only 1 of 7 out of the total of 4 sections.
<em>and</em>
2) the probability that the spinner will land on B.
Since the spinner is split into 3 equal sections, and there is only 1 sector for B, we can say the probability of getting B is 1/3.
To find the probability of 2 events, we need to multiply the two probabilities.
1/4*1/3 = 1/12
So the answer is 1/12.
The given function is
A . f(4) means we have to evaluate the function when x = 4.
<h2>Therefore, f(4) = 14.</h2>
B. f(x) = 50 means we have to evaluate the function when y = 50.-
<h2>Therefore, f(16) = 50.</h2>
C. f(-5) means we have to evaluate the function when x = -5.
<h2>Therefore, f(-5) = -13.</h2>
D. f(x) = -34.
<h2>Therefore f(-12) = -34.</h2>
