Answer:
-6x^2-1
Step-by-step explanation:
Find value
f(x)=-2x^2. g(x)=3x-1. Find g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
=g(-2x2)
=3⋅(-2x2)-1
=-6x2-1
gof(x)=-6x^2-1

You roll a 6-sided die.
What is P(5)?
Write your answer as a fraction or whole number.
Answer:
1/6
Step-by-step explanation:
there is one 5 on the die. therefore the chance of rolling a 5 is 1/6
The required probability P(5) = 1/6.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
The die has only one 5 on it.
The number of favorable outcomes = 1
There are the total outcomes as {1, 2, 3, 4, 5, 6}
So the total number of outcomes = 6
Required probability P(5) = 1/6
Hence, the chance of rolling a 5 is 1/6

The fraction 9 / 8 can also be written as [1/8 + 8/8] , [2/8 + 7/8] , [3/8 + 6/8]
What is a fraction?
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.
Given data ,
The number = 9 / 8
The number can be written as the sum of two different fractions as
a) 1/8 + 8/8 = (1+8)/8
= 9/8
b) 2/8 + 7/8 = (2+7)/8
= 9/8
c) 3/8 + 6/8 = (3+6)/8
= 9/8
Hence ,
The fraction 9 / 8 can also be written as [1/8 + 8/8] , [2/8 + 7/8] , [3/8 + 6/8]

Samuel spends $8 on lunch. The tax rate is 9%. What is his total cost?
Answer:
$8.72
Step-by-step explanation:
Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.
8 x (9/100) = tax
8 x 0.09 = 0.72
8+0.72 = $8.72

Step-by-step explanation:
So, we know it isn't D. We've narrowed it down to the top 3 answers now we would have to Divide 39 and 7 that would equal to 19.5. So, it could be A or B now. It says less 7 years, so we would know have to do this 39 - 7 = 32 32 / 2 = 16.
Therefore your answer is 16

Prove that when a polynomial function p(x) is divided by a first degree polynomial ax + b the remainder is p(-b/a)
Answer:
r = p(-b/a)
Step-by-step explanation:
Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.
Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.
So, p(x) = q(x)(ax + b) + r
Now, p(x) = r when q(x)(ax + b) = 0
since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a
⇒ p(x) = r when x = -b/a
So, r = p(-b/a)
So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)

Answer:
∠ YZX ≈ 19.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinZ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{7.5}{22.3}[/tex] , then
∠ YZX = [tex]sin^{-1}[/tex] ([tex]\frac{7.5}{22.3}[/tex] ) ≈ 19.7° ( to 3 significant figures )

A container can hold 18 litres of liquid. If there 7 2/3 litres of watee was poured into it, how much more water is needed to fill that container?
Answer:
Step-by-step explanation:
1 full container = 18 Liters.
The amount in the container = 7 2/3
The amount left to go is 18 - 7 2/3
Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3 If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3
17 - 5 = 12
3/3 - 2/3 = 1/3
So the answer is 12 1/3
