Step-by-step explanation:
C.
π/9 is less than sqrt(9) / 3 which is 1. Also, this question is quite ambiguous, and the answer could be none, because sqrt(9)/3 can also be -1
Since we know the slope of the line and a point that passes through it, we can use the <u>point-slope form formula</u> to determine the equation of the line.
Point slope form formula:

We are given the following:


When we substitute the values into the formula, we get;
<u />
<u />

Therefore, option B is correct.
Answer:
50
Step-by-step explanation:
<em>Substitute</em> 7 as x in the original equation, (9x-13)
<u>9(7)-13</u>
1) Multiply 9 and 7:
63-13
2) Subtract:
50
Answer:
256.56ft³
Step-by-step explanation:
V₍cone₎= πr²(h/3)
=π×(7)²×(5/3)
=(3.14)×(49)×(1.67)
=256.4ft³
