In order to solve the given problem above, we use

<span>t=<span><span>¬b</span><span>2a</span></span></span>; this would be a much easier method. <span>a=¬16</span> and <span>b=24</span>. We simply plug these values into, followed by simplifying the t value for the time, and then insert this value into <span>h(t)</span> for the height at t. This is one of the ways of determining the maximum of a quadratic function.

I think that using <span>t=<span><span>¬b</span><span>2a</span></span></span> is easiest; <span>a=¬16</span> and <span>b=24</span>. We simply plug these values in, simplify for the t value for the time, and then insert this value into <span>h(t)</span><span> for the height at t.</span>

For the smaller triangle ;
15^2 + b^2 = 17^2
b = 8

To check the work
15^2 + 8^2 = 289
17^2 = 289

(This is if the bottom number on the smaller triangle says 15, its a bit hard to read..)

Compute each sum below. If applicable, write your answer as a fraction.
Alex777 [14]

Answer:

First equation is -425

Second equation is 11.25

Step-by-step explanation:

First equation we can write as

\sum_{i=0}^7 5 \times (-2)^i

computing

When i=0 -> 5 \times (-2)^0 =5

When i=1 -> 5 \times (-2)^1 = -10

...

When i=7 -> 5 \times (-2)^7 = --640

then replacing each term we have

5  + (-10) + ( 20) + ( -40) +  (80) +( -160) +   320 + (-640) = -425

For the second equation we'll have 9 terms, solving in a similar fashion

When i=1 -> \frac{1}{4}1=0.25

When i=2 -> \frac{1}{4}2=0.50

When i=3 -> \frac{1}{4}3=0.75

...

When i=9 -> \frac{1}{4}9=2.25

So we have 0.25 + 0.50 + 0.75 + 1.00 + 1.25 + 1.50+ 1.75 +2.00 +2.25
