Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2

Answers

Answer:

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

        = x² - 16x + 64 + 3x - 24 + 2

        = x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

             = 64 + 104 + 42

             = 210

I need this question quick lol

Answers

Answer:

hey

b = 2

Step-by-step explanation:

Let's solve your equation step-by-step.

9+4b=17

Step 1: Simplify both sides of the equation.

4b+9=17

Step 2: Subtract 9 from both sides.

4b+9−9=17−9

4b=8

Step 3: Divide both sides

What is the sixth number in the Fibonacci sequence with the first two numbers 1 and 4?

Answers

Answer:

23

Step-by-step explanation:

1 + 4 = 5 so we get 1 4 5

then 4+5 = 9, 1 4 5 9

5+9 = 14, 1 4 5 9 14

9+14 = 23, so

1 4 5 9 14 23

23 is the 6th number in this sequence

The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.

Given :

Fibonacci sequence with the first two numbers 1 and 4.

The following steps can be used to determine the sixth number in the Fibonacci sequence:

Step 1 - If the first two numbers in the Fibonacci sequence is 1 and 4 then the third number is:

= 1 + 4

= 5

Step 2 - The Fourth number in the Fibonacci sequence is:

= 4 + 5

= 9

Step 3 - The Fifth number in the Fibonacci sequence is:

= 5 + 9

= 14

Step 4 - The Sixth number in the Fibonacci sequence is:

= 9 + 14

= 23

So, the sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23.

what is the area of the rectangle whose length is (x + 5) and width (x-5)​

Answers

Answer:

area of the rectangle is length *breadth

length =(x+5)

breadth =(x-5)

=(x+5)(x-5)=x^2-5x+5x-25=x^2-25

Answer:

[tex]\boxed {\boxed {\sf a=x^2-25}}[/tex]

Step-by-step explanation:

The area of a rectangle is the product of length and width.

[tex]a=l*w[/tex]

The length is (x+5) and the width is (x-5).

[tex]a= (x+5)(x-5)[/tex]

We have two binominals, so we can multiply using FOIL: First, Outside, Inside, Last.

F: x*x= x²O: x*-5= -5x I: x*5= 5x L: 5*-5 = -25

[tex]a= x^2-5x+5x-25[/tex]

Combine the like terms: -5x and 5x. They cancel each other out.

[tex]a=x^2-25[/tex]

The area of the rectangle is x²-25

Given a quadratic equation, how can you determine whether the parabola opens up or down?

Answers

Answer:
By whether x^2 has a negative or positive coefficient.

If the parabola opens down, x^2 has a negative sign in front of it.

If the parabola opens up, x^2 does not have a negative.

Explanation:
Completely expand a quadratic equation into this polynomial form to find “a”:
ax^2 + bx + c

When “a” is positive, the parabola opens up.

When “a” is negative, the parabola opens down.

A fair 10 sided die rolled until a 7 is first seen. What is the probability of rolling the die six times?

Answers

Answer:

The probability of rolling a dice six time until a 7 is first seen is 0.059

Step-by-step explanation:

The probability of getting a seven is equal to [tex]\frac{1}{10}[/tex]

The dice need to be rolled only six times.

This means that for the first 5 times the dice showed values other than 7 and in the last roll it displays 7

Hence the probability of rolling a dice six time until a 7 is first seen is

[tex](\frac{9}{10})^5 * (\frac{1}{10})^1[/tex]

[tex]= \frac{9^5}{10^6} \\= 5.90[/tex] % or 0.059
