Find the average rate of change between x=2 and x=4 for the function. F(x)=3x^3-1
Answer:
84Step-by-step explanation:
Average rate of change between x = 2 and x = 4 is:
[f(4) - f(2)]/(4 - 2) = (3*4³ - 1 - 3*2³ + 1)/2 = 168/2 = 84[tex]\boxed{\sf Average\: change=\dfrac{f(a)-f(b)}{a-b}}[/tex]
[tex]\\ \sf\longmapsto f(x)=3x^3-1[/tex]
[tex]\\ \sf\longmapsto f(4)=3(4)^3-1=3(64)-1=192-1=191[/tex]
[tex]\\ \sf\longmapsto f(2)=3(2)^3-1=3(8)-1=24-1=23[/tex]
Average change
[tex]\\ \sf\longmapsto \dfrac{192-23}{4-2}[/tex]
[tex]\\ \sf\longmapsto \dfrac{168}{2}[/tex]

what is the length of a short leg of a 30-60-90 triangle shown below?
Answer:
5
Step-by-step explanation:
since 30-60-90 triangles are special right triangles, we know that if the short leg=x, the long leg= xsqrt(3). so the short leg= 5 sqrt(3) /(sqrt(3) = 5
Evaluate the expression below when a = 5 and b = 2: a (10b - 2a).
Answer:
50Step-by-step explanation:
First, substitute the 2 given values into the expression.
a ( 10b - 2a )
5 ( 10(2) - 2(5) )
Simplify to the lowest terms possible, without distributing.
5(20-10)
Distribute 5 into each term.
100-50 or 20(5)-10(5)

The arithmetic sequence 1, 3, 5, 7, 9,. . . Represents the set of odd natural numbers. What is the explicit rule for the sequence? ak = (k - 1).
The explicit rule for the sequence is Tn = 2n - 1
Given the sequence 1, 3, 5, 7, 9...
The explicit formula for the nth term is expressed as:
[tex]T_n=a+(n-1)d[/tex]
a is the first term = 1
d is the common difference = 3 - 1 = 5 - 3 = 2
n is the number of terms
Substitute the given parameters into the formula to have;
[tex]T_n = 1+(n-1)(2)\\T_n=1+2n-2\\T_n=2n-1[/tex]
Hence the explicit rule for the sequence is Tn = 2n - 1

Answer:
[tex]\huge\boxed{318yd^2}[/tex]
Step-by-step explanation:
The object shown in the diagram is a triangular prism, which contains two triangular sides and three rectangular sides.
The area of a triangle is simply [tex]\frac{bh}{2}[/tex].
Because the triangles are both the same, you may multiply the equation by 2 to get simply bh, or 9 * 6, or 54.
Then, simply solve for the areas of each rectangle:
r1 = 11 * 7 = 77
r2 = 11 * 8 = 88
r3 = 11 * 9 = 99.
Then, simply add all the values to get:
99 + 88 + 77 + 54
318.
Hope it helps :) and let me know if you want me to elaborate.
There are 199 green marbles and 199 red marbles in a bag. How many marbles must be chosen to be certain we have the following. Four red or three green?
Answer:
203 for four red and 202 for three green.
Step-by-step explanation:
Consider the worst possible choice. If you want four red then imagine the worst possible case. That'd be picking all 199 marbles before any red, and after you pick all 199 green marbles you still need four red, and 199+4=203. For green, do the same thing and you get 199+3=202
There are 203 for four red and 202 for three green.
Given that,
There are 199 green marbles and 199 red marbles in a bag.Based on the above information, the calculation is as follows:
Since there is 4 red or three green.
So,
We can solve like
= 199 + 3
= 202
And,
= 199 + 4
= 203
Therefore we can conclude that there are 203 for four red and 202 for three green.
