Given:

The given sum is:

$\sum _{k=4}^9(5k+3)$

To find:

The expanded form and find the sum.

Solution:

We have,

$\sum _{k=4}^9(5k+3)$

The expanded form of given sum is:

$\sum _{k=4}^9(5k+3)=(5(4)+3)+(5(5)+3)+(5(6)+3)+(5(7)+3)+(5(8)+3)+(5(9)+3)$

$\sum _{k=4}^9(5k+3)=(20+3)+(25+3)+(30+3)+(35+3)+(4+3)+(45+3)$

$\sum _{k=4}^9(5k+3)=23+28+33+38+43+48$

$\sum _{k=4}^9(5k+3)=213$

Therefore, the correct option is C.

Point M is located at (-2,7). If point N is 10 units away from point M, how many possible cordinate pairs

natulia [17]

Answer:

2 possible coordinate pairs

N (8, 17) OR (-12, -3)

Step-by-step explanation:

The rule:

(x, y) => (x + 10, y + 10) OR (x - 10, y -10)

(-2 + 10, 7 + 10) OR (-2 - 10, 7 -10)

(8, 17) OR (-12, -3)

Hope this helps!

Find the equation of the line.

Stells [14]

To find the equation of the line, we need to figure out the slope and y-intercept.

To find the y-intercept, look at the number where the line intersects the y-axis. The number is 5. The equation so far is y = ?x + 5.

We still didn't figure out the slope yet. To figure out the slope, pick two points. Use the rise over run method. It is in the image below. The line is going up to the left, so the slope will be negative. Now we know the slope is -1/3. The equation now that we figured out the slope is y = -1/3x + 5.

I hope this helps you! Let me know if I got something wrong.

CALC!! Please help me. For which pair of functions f(x) and g(x) below will the limit as x goes to infinity of the product of f

Marizza181 [45]

First limit:
$\lim_{x\to\infty}(10x+e^{-x})*\frac{1}{5x}$
$=\lim_{x\to\infty}(2+\frac{1}{5xe^{x}})$
$=2+0$
$=2$

Since we know that the first pair of functions does not approach 0, we do not have to check the others.
