Answer:
-4
Step-by-step explanation:
To find the x-coordinate of the vertex of a parabola given its x-intercepts, find the average of the x-intercepts:
x-coordinate of the vertex = [tex]\frac{x_1+x_2}{2}[/tex] (where [tex]x_1[/tex] and [tex]x_2[/tex] are the x-intercepts)
Plug in the x-intercepts 13 and -21
[tex]\frac{13+(-21)}{2}\\= \frac{13-21}{2}\\= \frac{-8}{2}\\=-4[/tex]
Therefore, the x-coordinate of the vertex is -4.
I hope this helps!

c) How many applications will your mother actually use on her new cell phone? Solve the equation you wrote in part b to find the unknown variable. (2 points)
i put this in part B (She uses 24 applications regularly)
Answer:
24 would be the correct answer.
Step-by-step explanation:
24 would be the correct answer because 2/3 x 18 + 12 = 24.
Making 2/3 the the fraction that was used and already installed.
Making 18 the number of the already installed applications
Making 12 the number of the additional installed applications.
I hope this helped!!!
If f(x) = 3x + 1 and g(x) = 2x - 3, what is the product of f(-8) and g(6)?
A: 437
B: -207
C: -361
D: 171
Answer:
-207
Step-by-step explanation:
f(-8) = 3×(-8)+1
= -24+1
= -23
g(6) = 2×6-3
= 12-3
= 9
f(-8)×g(6) = -23×9 = -207

John needs to rewrite the expression (4x^3y^5z)^2. Identify which of the following is the simplified form of the expression.
4x^5y^7z^3
4x^6y^10z
8x^5y^7z^3
16x^6y^10z^2
Answer:
16x^6y^10z^2
Step-by-step explanation:
Well without doing much math I already know that (4x^3)^2 is 16x^6 because 4*4=16 and 3*2=6.
That leaves the last answer choice.

what is a sequence? How do I determine if a sequence is arithmetic or geometric?
Answer: Ok So Compute successive differences of the terms. If they are all the same, the sequence is arithmetic and the common difference is the difference you have found. If successive pairs of differences have the same ratio, the sequence is geometric The common pattern in an arithmetic sequence is that the same number is added or subtracted to each number to produce the next number. This is called the common difference. The common pattern in a geometric sequence is that the same number is multiplied or divided to each number to produce the next number.and the common ratio is the ratio you have determined.

10 different names are put into a computer, and one of them is Colin, the computer chooses 2 names at random. The computer is set so that the same name can be chosen twice. What is the probability that Colin is chosen at least once?
Answer:
0.19
Step-by-step explanation:
Given that :
Total possible outcomes = 10
If the same name can be chosen twice, then probability is with replacement ;
Probability = required outcome / Total possible outcomes
Required outcome = number of Collins in name = 1
Probability of choosing Collins atleast once ;
2[P(Collins) * P(not Collins)] + P(Collins) * P(Collins)
P(colins) = 1/10
P(not Collins) = 9/10
2(1/10 * 9/10) + (1/10 * 1/10)
2(9/100) + (1/100)
18/100 + 1/100
19/100
= 0.19

what is the value of x in the diagram below?
Answer:
x = 45
Step-by-step explanation:
These two angles are consecutive interior angles. This means they will add up to 180°. We use this information to make an equation.
x + 5 + 130 = 180
x + 135 = 180
x = 45
