Explain how knowing 50 x 4 = 200 helps you find 500 x 400.
Anika [276]
If you do 50 times 4 it’s easier to find 500 times 400 because all you have to do it add 3 more zeros behind 200 making the answer be 200,000.

Point A is at (3, -8) and point B is at (7, 3). What is the midpoint of line segment AB?​
allochka39001 [22]

Answer:

(5, -5/2)

Step-by-step explanation:

The midpoint of any line segment is the average of the x- and y-values of the two endpoints.

Therefore, the midpoint of AB is ((3+7)/2, (-8+3)/2)=(10/2, -5/2)=(5, -5/2).

So, the answer is \boxed{(5, -5/2)} and we're done!

I WILL MARK BRAINLIEST <br><br> 22 - 2x + 4(x - 2)= 34
lara [203]

Answer:

x = 10

Step-by-step explanation:

22 - 2x + 4(x - 2) = 34

22 - 2x + 4x - 8 = 34

22 - 8 - 2x + 4x = 34

14 + 2x = 34

-14           -14

--------------------------------

2x = 20

/2     /2

--------------------------------

x = 10

Ex 2.8<br> 3. find the maximum value of y for the curve y=x^5 -3 for -2≤x≤1
harkovskaia [24]
y=x^5-3\\ y'=5x^4\\\\ 5x^4=0\\ x=0\\ 0\in [-2,1]\\\\ y''=20x^3\\\\&#10;y''(0)=20\cdot0^3=0

The value of the second derivative for x=0 is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of 5x^4 is always positive for x\in\mathbb{R}\setminus \{0\}. That means at x=0 there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval [-2,1].
The function y is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.

y_{max}=y(1)=1^5-3=-2
