Given the function g ( x ) = x 2 + 10 x + 20 g(x)=x 2 +10x+20, determine the average rate of change of the function over the interval − 9 ≤ x ≤ − 3 −9≤x≤−3.
Step-by-step explanation:
the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
so,
(g(-3) - g(-9)) / (-3 - -9)
g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1
g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11
-3 - -9 = -3 + 9 = 6
(-1 - 11) / 6
-12/6 = -2
the average change rate in this interval is -2 (or fully -2/1).

Step-by-step explanation:
you do know that f(x) is the same as y ?
because the y value is the result of a function (in 2-dimensional space).
for such questions we only need to look at the term with the highest exponent of x.
with large values of x this term then "drowns" out all other terms regarding the dimension of the "limit" the range (= functional results) of the function can reach.
so, the term with the highest exponent of x is here
-4x⁶
all the other terms with x⁵, x⁴, x³, ... are much, much smaller in absolute value than |-4x⁶| for really large values of x (x going to infinity, but also to -infinity).
as explained, the term -4x⁶ is therefore driving the limit or end behavior of the function.
so, what happens here, when x goes to +infinity ?
then x⁶ goes to +infinity.
and that means 4x⁶ goes to +infinity.
but that means -4x⁶ goes to -infinity !
and when x goes to -infinity ?
then x⁶ still goes to +infinity (remember, multiplying 2 negative values gives a positive result, so any form of squaring incl. any even exponents will already have positive results).
and that means 4x⁶ goes to +infinity.
but again, -4x⁶ goes then to -infinity.
so the right answer choice is the second one, where y goes to -infinity in both cases.

Step-by-step explanation:
Sn = n/2(2a+(n-1)d)
a=6
a+ 4d= 18
6 +4d= 18
4d = 12
d = 3
162= n/2(12+(n -1)3)
324=n(12 + 3n-3)
324=12n + 3n^2 - 3n
3n^2 + 9n-324=0
3n^2+ 36n-27n -324 =0
3n(n+12) -27(n+12)= 0
3n-27 =0; n+ 12=0
n=9 ; n= -12
since n can't be negative n=9
The number of terms is 9

Answer:
m ∠ 2 = 19 * 3 = 57°
Step-by-step explanation:
m ∠ 1 = x
m ∠ 2 = 3x
m ∠ 1 + m ∠ 2 = 76°
3x + x = 76°
4x = 76°
Divide both sides by 4;
x = 19°
m ∠ 1 = 19°
m ∠ 2 = 19 * 3 = 57°

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the amount of money, M, he has after he has done laundry “x” times?
A) M= 7.50x - 240
B) M= 240 - 7.50x
C) M= 7.50 - 240x
D) M= 240x - 7.50
Answer:
B
Step-by-step explanation:
x = the number of times he does laundry.
Let's say he does the laundry 5 times then x = 5.
Each time costs $7,50.
If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.
M stands for how much money he still has left from the 240 dollars.
If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'
Therefore, the correct answer is B (M = 240 - 7.50x).

The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 4x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
A)1
B)2
C)3
D)4
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.
Step-by-step explanation:The rate of change is also known as slope. The slope of a linear function or a line is
It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is
Therefore the slope of first function is 0.
The slope intercept form of a line is
Where, m is the slope and b is y-intercept.
The second function is
Therefore the slope of second function is 2 and the y-intercept is 1.
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

A newborn baby has about 26,000,000,000 cells. An adult has about 4.94 x 10^*13 cells. How many times as
many cells does an adult have than a newborn? Enter your answer in scientific notation.
An adult has about =
times more cells than a newbom baby.
New born = 2.6 × 10¹⁰ cells.
Adult = 4.94 × 10¹³ cells.
How many times more = adult cells ÷ newborn cells
= 4.94 × 10¹³ cells ÷ 2.6 × 10¹⁰ cells
= 1.9 × 10³ cells
∴ adults have about 1.9 × 10³ more cells than newborn babies.
