What is the mean? 20,22,25,28,29,30,32,33,34 ( Show work )
Answer:
28 or 28.11111 because I don't know if it asked you to round or not.
Step-by-step explanation:
Mean is the average of a group of number added together and divided by the number of number there are.
20+22+25+28+29+30+32+33+34 = 253
Now we will divide by the number of numbers we have there are 9 numbers.
Soooo.
253/9= 28.1111111
(Round)
28
Answer:
28 1/9 or 28.1111... (0.1 repeating)
Step-by-step explanation:
20 + 22 = 42
42 + 25 = 67
67 + 28 = 95
95 + 29 = 124
124 + 30 = 154
154 + 32 = 186
186 + 33 = 219
219 + 34 = 253
253 / 9 = 28 1/9 or 28.11111...

Plz help with graph polynomial
Answer:
(x + 1 ) is a factor
Step-by-step explanation:
Given a polynomial with roots x = a, x = b , then the corresponding factors are
(x - a) and (x - b)
From the graph
The roots are x = - 1 and x = 4 , thus factors are
(x - (- 1)) and (x - 4) , that is
(x + 1) and (x - 4)
(x + 1) is the required factor

+6x+12, determine the average rate of change of the function over the interval -3\le x \le 5−3≤x≤5.
Answer:
4
Step-by-step explanation:
edge
The average rate of the function is 4.
What is average rate of function?The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,
A(x) = (change in outputs) / (change in inputs)
= Δy / Δx
= [f(b) - f(a)] / (b - a)
given function:
f(x) = -x² + 6x + 12
Now,
let a= -3, b = 5
and, f(b)= -(5*5) + 6*5 + 12
=-25+ 30 +12
= 17
f(a) = -(- 3 * (-3))+6(-3) +12
= -9-18+12
= -15
Now,
f(b)- f(a) / (b-a)
=17 -(-15))/5-(-3)
=32/ 8
=4

Find the difference quotient for f(x) = 3x2 – 12.
_x+_h
The difference quotient for f(x) = 3x2 – 12 is 6x + 3h
How to determine the difference quotient?The function is given as:
f(x) = 3x^2 – 12.
Calculate f(x + h)
f(x + h) = 3(x + h)^2 – 12
The difference quotient is then calculated using:
[tex]f'(x) = \frac{f(x + h) - f(x)}{h}[/tex]
This gives
[tex]f'(x) = \frac{3(x + h)^2 - 12 - 3x^2 + 12}{h}[/tex]
Evaluate the difference
[tex]f'(x) = \frac{3(x + h)^2- 3x^2}{h}[/tex]
Expand
[tex]f'(x) = \frac{3x^2 + 6xh + 3h^2- 3x^2}{h}[/tex]
Evaluate the difference
[tex]f'(x) = \frac{6xh + 3h^2}{h}[/tex]
Evaluate the quotient
f'(x) = 6x + 3h
Hence, the difference quotient for f(x) = 3x2 – 12 is 6x + 3h

Answer:
x^2 -5x +6 = 0
Step-by-step explanation:
Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...
(2x -1)(3x -1) = 0 ⇒ roots 1/2, 1/3
Then the factoring of the equation with reciprocal roots is ...
(x -2)(x -3) = 0

The measure of an angle is 66° . What is the measure of its complementary angle ?
Answer:
24º
Step-by-step explanation:
90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.
Answer:
The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).
Step-by-step explanation:
A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.
Let's call the smaller angle x
We also know that the larger number is 66° more than the smaller. This gives us:
x+x+66°=180°.
x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.
Now we can simplify this by subtracting 66° from both sides.
