Find the coordinates of the midpoint of AS if A(-4, 7) and S(5,3).
lesya692 [45]

Answer:

The answer is

<h2>( \frac{1}{2}  \: ,  \: 5)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-4, 7) and S(5,3)

The midpoint is

<h3>M  = ( \frac{ - 4 + 5}{2} , \:  \frac{7 + 3}{2} ) \\  = ( \frac{1}{2} , \:  \frac{10}{2} )</h3>

We have the final answer as

<h3>( \frac{1}{2}  \: ,  \: 5)</h3>

Hope this helps you

How do i use Scientific notation on these problems? Because I don't know...
saveliy_v [14]

Answer:

Simplify the problems first

Step-by-step explanation:

Before you can convert it to scientific notation, you should simplify it first.

#1 for example:

(4 \times 10^5)^2\\

Use PEMDAS to solve the equation:

(4 \times 10^5)^2\\= 400000^2\\= 160000000000

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be  1.6 \times 10^{11} since there are 11 places after the decimal.

Andrei [34K]

Answer:

a. ∫ xSinx dx

iii. integration by parts

u =x and dv= sinx

b. ∫ x⁴/(1+x³). dx  

ii. neither

Long division is an option here before integration is done

c. ∫ x⁴. e^x³. dx

i. substitution

where u = x⁵

d. ∫x⁴ cos(x⁵). dx

i. substitution

where u = x⁵

e. ∫1/√9x+1 .dx

i. substitution

where u = 9x+1
