<h2>Value of f(-10) is 1100</h2>

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

  f(-10) =  (-10)² - (-10)³

  f(-10) = 100 - (-1000)

  f(-10) = 100 + 1000

  f(-10) = 1100

Value of f(-10) is 1100

The function y=−0.25x+0.55 represents the percent y (in decimal form) of battery power remaining x hours after you turn on a lap
AURORKA [14]
Answer: a is 2.2, b is 0.55
Explanation:
To find the x intercept, put 0 instead of y,
hence,
0=-0.25x+0.55
-0.25x=-0.55
x=2.2
To find y intercept put 0 instead of x,
so,
y=-0.25*0+0.55
y=0+0.55
y=0.55

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
