Answer: The average rate of change of the function in that interval is r = -1
Step-by-step explanation:
When we have a function f(x), the average rate of change in an interval:
a ≤ x ≤ b
Is calculated as:
[tex]rate = \frac{f(b) - f(a)}{b - a}[/tex]
In this case, the function is:
y = f(x) = (1/2)*x^2 - 1
And the interval is:
-2 ≤ x ≤ 0
Then the rate of change will be:
[tex]rate = \frac{f(0) - f(-2)}{0 -(-2)} = \frac{((1/2)*(0)^2 - 1) -((1/2)(-2)^2 - 1)}{2} = \frac{-2}{2} = -1[/tex]
The average rate of change of that function in that interval is r = -1

When an equation has one (1) solution, the variable terms on both sides are the same: False.
What is system of equations?A system of equations can be defined as an algebraic equation of the first order with two (2) variables and each of its term having an exponent of one (1).
Mathematically, an equation can be represented as follows:
[tex]x+y=10[/tex]
Where:
x and y are the variable terms.Generally, the variable terms on both sides are different for an equation that has one (1) solution.

If f(x) = x - 4, find f(10)
Answer:
f(10) = 6
Step-by-step explanation:
To evaluate f(10), substitute x = 10 into f(x), that is
f(10) = 10 - 4 = 6
What is the measure of ONE interior angle in a regular triangle (3 sides)?

Price-club sells a 12-ounce box of crackers for $2.59 and Shop Mart sells a 1-pound box of crackers for $4.68. The unit price at Price-Club is $ per ounce, and the unit price at Shop Mart is $ per ounce.
Answer:
$0.216 and $0.293
Step-by-step explanation:
Given,
Price club sells 12 ounce box = $2.59
Shop mart sells a 1 pound box = $ 4.68.
We have to find the unit price at Price club and Shop mart.
We know that 1 Pound = 16 ounce
Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]
= $0.216
Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]
= $0.293
because I got this question too. On odysse.yware.
Answer:
0.21 and 0.19
Step-by-step explanation:
It's simple, just divide it.
Divide 2.59 by 12 and divide 4.68. Then round the answers to the closest number in the choices. That's your answer buddy!

Count to find the slope.
Answer:
The slope is 6/7 or -7/6.
Step-by-step explanation:
You could go from the lower dot and count to the line of the upper dot and then go to the right until you hit the dot or you would start at the upper dot and count down to the line of the lower dot and go to the left until you hit the dot.
In this triangle, the product of sin B and tan C is
and the product of sin Cand tan B is
Answer:
[tex]\frac{c}{a}[/tex] and [tex]\frac{b}{a}[/tex]
Step-by-step explanation:
sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{b}{a}[/tex]
tanC = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{c}{b}[/tex]
Thus
sinB tanC = [tex]\frac{b}{a}[/tex] × [tex]\frac{c}{b}[/tex] ( cancel b on numerator/ denominator )
= [tex]\frac{c}{a}[/tex]
---------------------------------------------------------------------------
sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{c}{a}[/tex]
tanB = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{b}{c}[/tex]
Thus
sinC tanB = [tex]\frac{c}{a}[/tex] × [tex]\frac{b}{c}[/tex] ( cancel c on numerator/ denominator )
= [tex]\frac{b}{a}[/tex]
Scale Factor = 1 is it reduction or enlarge
Answer:
The image remains the same.
Step-by-step explanation:
If the scale factor is one, then the image is not reduced or increased, it remains the same. This is because, if one multiplies the original image by the scale factor, then one will get the scaled answer. If one multiplies anything by 1, then they will get the number they multiplied by 1 (this is called the multiplicative identity property), hence the image remains the same.

Subtract (4x2 - x + 6) from (3x2 + 5x - 8).
A. O 7x2 + 6x - 14
B. 7x2 + 4x - 2
C.x2 - 6x + 14
D. -x2 + 6x - 14
Answer:
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]
Hence, option D is correct.
Step-by-step explanation:
We have to subtract (4x² - x + 6) from (3x² + 5x - 8).
so
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)[/tex]
Remove parentheses: [tex]\left(a\right)=a[/tex]
[tex]=3x^2+5x-8-\left(4x^2-x+6\right)[/tex]
[tex]=3x^2+5x-8-4x^2+x-6[/tex]
Group like terms
[tex]=3x^2-4x^2+5x+x-8-6[/tex]
Add similar elements: [tex]\:3x^2-4x^2=-x^2[/tex]
[tex]=-x^2+5x+x-8-6[/tex]
Add similar elements: [tex]5x+x=6x[/tex]
[tex]=-x^2+6x-8-6[/tex]
Subtract the numbers: [tex]-8-6=-14[/tex]
[tex]=-x^2+6x-14[/tex]
Therefore,
[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]
Hence, option D is correct.
