PLEASE HELP, TWENTY POINTS PLUS BRAINLIEST
Write an explicit function to represent the following sequence.
3,9, 27, 81,...

Answer:

y = 4x - 6

Step-by-step explanation:

The y-intercept is the point where x is equal to 0. Therefore, the y-intercept is -6.

To find the slope we need to take 2 points and put them in the slope formula:

[tex]slope = \frac{y2-y1}{x2-x1}[/tex]

I am going to use the points (3,6) and (4,10). Plug these in to the equation:

[tex]\frac{10 - 6}{4 - 3} = \frac{4}{1} = 4[/tex]

The slope is 4.

The whole equation can be written now:

y = 4x - 6

I hope this helps!

48√2 in the simplest form of the expression √192.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can simplify the √192 by factoring it into its prime factors:

192 = 2 × 2 × 2 × 2 × 2 × 3 × 3

Then, we can group the prime factors into pairs of two:

192 = (2 × 2) × (2 × 2) × (2 × 3) × 3

Simplifying each pair of factors under the square root gives:

[tex]\sqrt{192} = \sqrt{(2\times2)}\sqrt{(2\times2)}\sqrt{(2\times3)}\sqrt{3}\\= 4\times4\times\sqrt{6}\sqrt{3} \\= 16\sqrt{6}\sqrt{3}[/tex]

Finally, we can simplify the expression by multiplying the coefficients and combining the square roots:

[tex]16\sqrt{6}\sqrt{3} \\= 16\sqrt{18} = 16\sqrt{2\times3\times3} \\= 16\times3\sqrt{2} \\= 48\sqrt{2}[/tex]

Therefore,

48√2 in the simplest form of the expression √192.

Answer:

All but the second one

Step-by-step explanation:

Find the inverse of each function:

b(x)=x^2+3

y=x^2+3

x=y^2+3

x-3=y^2

sqrt(x-3)=y

This inverse function is a function

d(x)=-9

y=-9

This doesn't have an inverse function

m(x)=-7x

y=-7x

x=-7y

-1/7x=y

This inverse function is a function

p(x)=|x|

y=|x|

x=|y|

x=y

This inverse function is a function

Therefore, all but the second function have inverses that are functions

Answer:

All but the second one have inverse functions

Answer:

There will be 330 7th grade students in this middle school this year.

Step-by-step explanation:

Last year enrollment = 150 students

As the enrollment increased by 120%.

i.e.

Number of Percentage increase = 120% × 150 = 120/100 × 150

                                                       = 1.2 × 150

                                                        = 180

Thus,

Total students this year = No. of Percentage increase + Last year students

                                       = 180+150

                                        = 330 students

Therefore, there will be 330 7th grade students in this middle school this year.

Step-by-step explanation:

Answer:

Step-by-step explanation:

ok slope is m because there is a thing called y-intercept, so you use x to find slope.

the whole formula is y = mx +b

in this case m = slope with x being the part of the slope from where you got it from

the answer would be m = [tex]\frac{1}{2}[/tex]x

5 Easy as 1-2-3

5 is a prime number.

Prime factorization: 5 is prime.

The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.

Factors of 5: 1, 5.

Factor pairs: 5 = 1 x 5.

5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.
