What is the value of k in the function ƒ(x) = 112 - kx if ƒ(-3) = 121?

DedPeter [7]

f(x) = 112 - kx
f(-3) = 112 - k(-3)
f(-3) = 112 - (-3k)
f(-3) = 112 + 3k
121 = 112 + 3k
- 112 - 112
      9 = 3k
      3    3
      3 = k

What is the arc length of ACB?

Debora [2.8K]

Answer:

C. 82.43

acb's angle is 315 degrees because

360 - 45 = 315

arc length is in radians

arc length is radius times (angle times (pi÷180))

arc length is 15 times (315 times (pi÷180))

arc length is 82.43

Find the 11th partial sum of the summation of negative 7i plus 22, from i equals 1 to infinity.

marta [7]

I think you mean,

$\sum_{i=1}^{\infty}(7i+22)$

You can use the usual formula,

$S_{k}=\frac{k}{2}(a_1+a_k)$

That in this case is,

$S_{11}=\frac{11}{2}(29+99)=704$

Where I have used,

$a_k=7\cdot k +22$
