Step-by-step explanation:
Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.

The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?
Answer:
8.82 feet
Step-by-step explanation:
Explanation:
Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:
Model length
Ship length
=
1 Model length
100 actual length
And we can drop in some numbers (I'll also put in the variable
x
to represent the length of the ship model):
x
882
=
1
100
Let's cross multiply to solve for x:
100
x
=
882
x
=
8.82

Answer:
8x·x·x·x·x·x
Step-by-step explanation:
Using the rules of exponents, this simplifies to ...
[tex](2x^2)^3 = 2^3x^{2\cdot3}=8x^6=\boxed{8\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}[/tex]

The applicable rules of exponents are ...
(a^b)^c = a^(bc)
(ab)^c = (a^c)(b^c)
Of course, an exponent signifies repeated multiplication.

Orlo uses a spool of wire to make 15 necklaces.
At this rate, how many spools of the same size would he use to make 50 necklaces?
he would use to make 50 necklaces 4 spools of the same size.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given this, Orlo uses a spool of wire to make 15 necklaces.
Since she requires 15 necklaces = 1 spool of wire
So, requirement for 1 necklace = 1/15 spool of wire
Thus,
requirement of wire for 50 necklace = 50/15 spool of wire
requirement of wire for 50 necklace = 10/3 spool of wire
requirement of wire for 50 necklace = 3.33 spool of wire
Therefore, 4 spools of the same size he would use to make 50 necklaces.

Use the associative property to write an expression equivelent to (w + 9)+3
Answer:
w+ (9+3)
Step-by-step explanation:
pretty simple if I remember how to use that property
Answer:
The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
Solution:
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
