What is the average rate of change from x = −1 to x = 2?
A. −3
B. −1
C. 1
D. 3

Answers

we have

$f(x)=x^(4)-4x$

Step 1

Using the table find the value of f(x) for $x=-1$

$x=-1\nf(-1)=5$

Step 2

Using the table find the value of f(x) for $x=2$

$x=2\nf(2)=8$

Step 3

Find the average rate of change

we know that

the average rate of change is equal to the formula

$(f(b)-f(a))/(b-a)$

in this problem we have

$f(b)=f(2)=8$

$f(a)=f(-1)=5$

$b=2$

$a=-1$

substitute the values in the formula

$(8-5)/(2+1)$

$(3)/(3)=1$

therefore

the answer is the option C

the average rate of change is $1$

$A(x) = (f(x) - f(a))/(x - a) = (f(-1) - f(2))/(-1 - 2) = (5 - 8)/(-3) = (-3)/(-3) = 1$
The answer is C.

the product gives the coordinates of two points on line AB that has been rotated 90 degrees counterclockwise about the origin. name the coordinates of A’ and B’.

Answers

Since you haven't provided the coordinates of A and B, I cannot give an exact answer. However, I will help you with the concept.

Rotation 90° about the origin will result in the following:
(x,y) ..........> (-y,x)

Therefore, you have to multiply the y value by -1 and then flip the x and y.

Examples:
(2,9) ..........> Rotation 90° about the origin .........> (-9,2)
(-3,4) .........> Rotation 90° about the origin .........> (-4,-3)
(-1,0) ..........> Rotation 90° about the origin .........> (0,-1)
(8,-6) ..........> Rotation 90° about the origin .........> (6,8)

Hope this helps :)

Simplify fully
a) 8c²d^5 ÷ 2c³d³
b) 9a³b^5 ÷ 3ab²

Answers

Answer:

Step-by-step explanation:

In exponent division, if base are same , subtract the exponents.

$(a^(m))/(a^(n))=a^(m-n) , m>n\n\n (a^(m))/(a^(n))= (1)/(a^(n-m)), m<n$

a) 8c²d⁵ ÷ 2c³d³ = $(8)/(2)* (d^(5-3))/(c^(3-2))= 4*(d^(2))/(c)= (4d^(2))/(c)$

b) 9a³b⁵ ÷ 3ab² = $(9)/(3)* a^(3-1)*b^(5-2) = 3a^(2)b^(3)$

Answer:

A) 8d^2/3c

B) 3a^2b^3

For what values of the variables must ABCD be a parallelogram?

Answers

okfirst things first. In all parallelograms, you now that opposite anglesare numerically equal to each other and that the sum off all fourangles must add up to 360.

Therefore based off the picture, angles B and D are equal to each other, and A and C are equal to each other.

(2x-10) = (y+20) B = D
y=2x-30

Now B = 2x -10 and D = 2x-30+20 = 2x-10

Now A = C

Since A = 2x+ 10, we can assume C = 2x + 10

Now we need to find the value of x

so our angle A, B, C, and D add up to 360 so the "master equation" is:

(2x - 10) + (2x - 30 + 20) + (2x + 10) + (2x + 10) = 360
2(2x -10) + 2(2x + 10) = 360
4x - 20 + 4x + 20 = 360
8x = 360
x = 45

Now that we know what x is, we can go back to the angles B and D

remember B = 2x - 10 and D = y + 20

and earlier we stated that y=2x-30
therefore y = 2(45) - 30
Y = 60

Now if you wanted to double check, all you have to do is plug in the xand y values into the equations and add up all the angles together andthey should add up to 360.

I know I kinda went into too many details, but I'd rather explain itinto too much detail rather than too few details and shortcuts that youwouldn't be able to follow and understand.

I hope this was helpful =D

Final answer:

ABCD is a parallelogram if either both pairs of opposite sides are parallel, both pairs of opposite sides are equal, or one pair of opposite sides is both parallel and equal.

Explanation:

In mathematics, a quadrilateral ABCD is considered a parallelogram if it meets one of these three conditions:

Both pairs of opposite sides are parallel (AB || DC and AD || BC).
Both pairs of opposite sides are equal (AB = DC and AD = BC).
One pair of opposite sides is both parallel and equal (AB = DC and AB || DC).

So, the values of the variables you have in your problem have to satisfy at least one of these conditions to make ABCD a parallelogram.
