Step-by-step explanation:
Exponent rule:
[tex]\sf \boxed{\bf (a^m)^n=a^{m*n}}[/tex]
To simplify [tex]\sf(7^2)^6[/tex] multiply the powers.
[tex]\sf (7^6)^2=7^{6*2}[/tex]
[tex]\sf = 7^{12}[/tex]
scale A is the image figure of scale B
Answer:
x=20
Step-by-step explanation:
12.5/1.25=10
This means that to get from Figure B to A, you would need to divide by 1.25
So to get from Figure A to B, you would have to multiply by 1.25
16*1.25=20
The Questions above.
Answer:
It's B.9
Step-by-step explanation:
Because
11+9=20
20+9= 29
29+9= 38
The common difference is positive because the arithmetic sequence is increasing.
Answer:
B. arithmetic sequence; 9
Step-by-step explanation:
An arithmetic sequence is a sequence where there is a common difference between each term. A common difference is a number that is added to the previous term to get the current term. For a sequence to be considered arithmetic this common difference must remain constant. This sequence is arithmetic because each time 9 is added to the previous term to get the next one. So the common difference is 9 and B is correct.

A recipe calls for 2 cups of flour and 3 eggs and it serves 8 people. If Mrs. Nguyen wants to make the recipe for her class of 32 students, how much flour and how many eggs should she use?
Answer:
She would need 8 cups of flour and 12 eggs.
Step-by-step explanation:
32 divided by 8 = 4 so you will then you multiplication and times everything in the recipe by 4.
Jeremy was 45 inches tall when he started kindergarten. He grew an average of 2.5
inches every year. Jeremy is now 62.5 inches tall.
Which equation can be used to find how many years ago Jeremy started kindergarten,
and how many years ago was it?
Answer:
subtraction
Step-by-step explanation:
its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it

Use the discriminant to describe the number of solutions of the equation 2x^2+5x−12=0
Multiple choice question.
A)
The discriminant is 121, and the equation has two real, rational roots.
B)
The discriminant is 121, and the equation has one real, rational root.
C)
The discriminant is –71, and the equation has two real, irrational roots.
D)
The discriminant is –71, and the equation has two complex roots.
Answer:
a = 2
b = 5
c = -12
The discriminant is sqr root (b^2 - 4*a*c)
= sqr root (25 -4 * 2 * -12)
= sqr root (25 + 96)
= sqr root (121)
Answer is A)
Step-by-step explanation:
Jack has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 12.5 points for each visit to the movie theater. He needs at least 205 points for a free movie ticket. Write and solve an inequality which can be used to determine vv, the number of visits Jack can make to earn his first free movie ticket.
Answer: See explanation
Step-by-step explanation:
Since Jack receives 55 rewards points just for signing up and earns 12.5 points for each visit to the movie theater and needs at least 205 points for a free movie ticket.
The inequality which can be used to determine v, the number of visits Jack can make to earn his first free movie ticket will be:
55 + 12.5v ≥ 205
12.5v ≥ 205 - 55
12.5v ≥ 150
v ≥ 150/12.5
v ≥ 12
The number of visits that Jack can make to earn his first free movie ticket will be at least 12 visits

Step-by-step explanation:
what is the importance of knowing the roots of real numbers
Answer:
While imaginary numbers offers unique insights, we live in a real world. Real numbers provide a model that fits many (most) of the day to day situations people encounter every day. Understanding real numbers and having a sense for what they are and ow they can be used to model 'the real world' is a skill every intelligent person must master.

How does knowing one linear factor of a polynomial help find the other factors?
Answer:
How does knowing one linear factor of a polynomial help find the other factors?
Step-by-step explanation:
f(x)=(x−3)(x−1)(x+2)(x+6)
f(x)=(x−2)(x−2)(x+3)(x+5)
f(x)=(x−5)(x−3)(x+2)(x+2)
f(x)=(x−8)(x−1)(x+3)(x+5)
f(x)=(x−2)(x−1)(x+4)(x+4)
Correct answer:
f(x)=(x−2)(x−2)(x+3)(x+5)
Explanation:
We begin by attempting to find any rational roots using the Rational Root Theorem, which states that the possible rational roots are the positive or negative versions of the possible fractional combinations formed by placing a factor of the constant term in the numerator and a factor of the leading coefficient in the denominator.
That was a lot of wordage in one sentence, so let's break that down. We begin with our polynomial.
f(x)=x4+4x3−13x2−28x+60
The constant term is the term without a variable (just a plain number). In our case the constant is 60. What are the possible factors of 60?
1,2,3,4,5,6,10,12,15,20,30,60
The leading coefficient is the number in front of the largest power of the variable. When the terms are listed in descending order (highest to lowest power), the leading coefficient is always the first number. In our case the leading coefficient is hard to spot. Since there is no number in front of x4, the coefficient is 1 by default.
This is nice because the only factor of 1 is well ... 1.
We then create all the possible fractions with a factor of the constant in the numerator and a factor of the leading coefficient in the denominator. This actually isn't as bad as it could be since our only possible denominator is 1. Any fraction with a denominator of 1 is just the numerator. Therfore, our possible "fractions" are simply
1,2,3,4,5,6,10,12,15,20,30,60
However, we must consider the positive or negative versions of these, so our final list of possible rational roots is
±1,±2,±3,±4,±5,±6,±10±,1±2,±15,±20,±30,±60
Unfortunately, this is where the process (at least without the assitance of a graphing calculator) becomes less fun. Using synthetic division, we must simply try each possible root until we have success. There's really no consistent rule to tell us where to start. Generally starting with the smaller whole numbers is best because the synthetic division is easier. Therefore, we could begin with 1 then proceed to −1,2,−2, etc.
For the sake of keeping this explanation as short as possible, I am going to skip straight to 2, where we will first find success.
Therefore, 2 is a root. However, it is always important to check to see if a root is in fact a double root (it works twice). Therefore, let's try it one more time.
2 does in fact work twice and is thus a double root. Since we only have three terms remainng, we can convert from synthetic back to an algebraic expression.
f(x)=x2+8x+15
We can then factor.
f(x)=(x+3)(x+5)
Writing our root of 2 as an algebraic expression gives (x−2). Since we have double root, we need two of these. Therfore, our final factored expression is.
f(x)=(x−2)(x−2)(x+3)(x+5)
The surface area of the triangular prism pictured below is 204 square centimeters. What is the height of the prism?
Answer:
height x=21.5cm
Step-by-step explanation:
Surface area = 2+ area of triangles + area of the 3 rectangles
SA = 204
204 = 4*3 + x*5 + 5*4 + x*3
204 = 12 +20 +8x
204 -12-20 = 8x
172/8 = x
21.5 = x

It's not a linear equation, but its grapg is a straight line.
It is a linear equation, and its graph is a straight line.
It's not a linear equation and its graph is not a straight line.
it's a linear equation, but the graph is not a straight line
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
The graph of y=mx+b is a straight line as it is the line equation.Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
