COLLEGE Troy’s grandfather gave him $700 to start his college savings account. Troy’s grandfather also gives him $40 each month

expeople1 [14]

Simplified expression for the amount is 10(9m + 50)

Step-by-step explanation:

Step 1: Form an equation for the amount of money Troy has received after m months.

If the total months that Troy's grandfather has given him money is m, then the number of months that Troy's mother has given him money is m - 4.

⇒ Total amount in account = 700 + 40m + 50(m - 4)

= 700 + 40m + 50m - 200

= 90m + 500 = 10(9m + 50)

Tell whether the lines that pass through the following points are parallel,

wel

Answer:

These Lines will be parallel.

Step-by-step explanation:

You have to find the slope of each line. For (1,1) and (3,3) the slope is 1 and for Line 2 the slope is also 1. (let me know if you want me to show the work for slope). To have parallel lines the slopes have to be the same and y-ints have to be different. Here the slopes are the same and in Line 1 the yint is (0,0) which is different than Line 2. Therefor the Lines are parallel.

Sorry if im wrong!. Hope this helps

When f(x) is a differentiable function

Paul [167]

Presumably, the first limit is some finite number

$\displaystyle \lim_{x\to\pi} \frac{f(x)}{x-\pi} = c$

Since x - π clearly approaches 0 as x approaches π, we must also have f(x) approaching 0,

$\displaystyle \lim_{x\to\pi} f(x) = 0$

Recall the double angle identity,

sin(2t) = 2 sin(t) cos(t)

and rewrite the limit as

$\displaystyle \lim_{x\to\pi} \frac{\sin(2 f(x))}{x - \pi} = \lim_{x\to\pi} \frac{2 \sin(f(x)) \cos(f(x))}{x - \pi} = 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi}$

Recall that

$\displaystyle \lim_{x\to0}\frac{\sin(x)}x=1$

which means

$\displaystyle \lim_{x\to\pi}\frac{\sin(f(x))}{f(x)} = \lim_{f(x)\to0}\frac{\sin(f(x))}{f(x)} = 1$

and by continuity,

$\displaystyle \lim_{x\to\pi} \cos(f(x)) = \cos\left(\lim_{x\to\pi} f(x)\right) = \cos(0) = 1$

Then

$\displaystyle 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi} \\\\ = 2 \left(\lim_{x\to\pi}\frac{\sin(f(x))}{f(x)}\right) \left(\lim_{x\to\pi} \frac{f(x)}{x-\pi}\right) \left(\lim_{x\to\pi}\cos(f(x))\right) \\\\ = 2 \times 1 \times c \times 1 = \boxed{2c}$
