A manufacturer claims that their cans of paint contain exactly 130 fluid ounces of paint. The amount of paint in each can of paint must be accurate within ±3.05 fluid ounces of the actual amount of paint. a. Write an absolute value inequality to represent the possible amount of paint, in fluid ounces, p for which the manufacturer’s claim is correct. b. Graph the solution set of the inequality you wrote in part a.
Answer:
3.0232 ounces per can of paint and 43 cans in 130 ounces of fluid
Step-by-step explanation:
130 ounces of fluid divided by ±3.05 and for me it was easier to reach by approximation
The explicit formula for a sequence is f(n)
What is the value of f(3)?
19 + 6n
Answer:
f(3) = 37
Step-by-step explanation:
If the formula for this arithmetic sequence is f(n) = 19 + 6n, then the value of f(3) is 19 + 6(3), or f(3) = 37

(x)=4(x+3)(3x-8) in standard form
Answer:
12x² +3x = 96
Step-by-step explanation:
x = 4(x + 3)( 3x - 8)
x = (4x + 12) (3x - 8)
x = 4x(3x - 8) + 12(3x - 8)
x = 12x² - 32x + 36x - 96
x = 12x² + (-32x + 36x) - 96
x = 12x² + 4x - 96
0 = 12x² + 4x -x - 96
0 = 12x² + 3x -96
96 = 12x² + 3x same as 12x² +3x = 96
Solve the expression and find the value of x.

Take a look at the denominators. The denominators are 10, 5 & 1. Their LCM is 10. So, multiply the fractions on both the sides of the equation by 10.

Now, simplify it.

Proportions and Percents: solve using a proportion or an equation
Due to inflation, a used Mercedes has gone up 22% from its original price of 48,000 dollars. How much does the car cost now?
Answer:
$58,560
Step-by-step explanation:
First step: set up your proportion equation. Keeping the percents on the bottom, I set it up as $48,000/100% = $x/122%. I'm writing it as 122% rather than 22% so we don't have to add the increase in price to the original price later. You can see that, in order to get from 100 to 48,000, you need to multiply by 480, so you can do this to 122 to get x. Your teacher might, instead, want you to cross multiply. Do what's expected of you. Either way, your result should be $58,560. Check that it makes sense by checking that it's an increase and that it looks reasonable for the amount of the increase and you're done.

A Strong wind blows to the west at a speed of 38.7 mph relative to the ground causing a commercial plane to change course. What should be the plane's velocity in order to maintain a southward direction at a constant speed of 452 mph relative to the ground?
The speed of the plane is the rate of change of distance over time
The speed of the plane should be 453.65 mph southwest
The speed of the wind is given as:
[tex]\mathbf{S_w = 38.7mph}[/tex]
The expected speed of the plane is:
[tex]\mathbf{S_s = 452mph}[/tex]
So, the actual speed is calculated using the following Pythagoras theorem
[tex]\mathbf{S_{sw}^2 = S_w^2 + S_s^2}[/tex]
This gives
[tex]\mathbf{S_{sw}^2 = 38.7^2 + 452^2}[/tex]
[tex]\mathbf{S_{sw}^2 = 205801.69}[/tex]
Take square roots of both sides
[tex]\mathbf{S_{sw} = 453.65}[/tex]
Hence, the speed of the plane should be 453.65 mph southwest

Write down the equation of a line whose slope is 5 and crosses the y-axis at -6. Express in slope-intercept form.
Answer:
Y= 5x-6
Step-by-step explanation:
The slope intercept form is y=mx+b. The m stands for your slope. The b stands for the y-intercept. So, plug in the slope of 5 for m, then plug in -6 of b and then your equation should end up as y=5x-6. Hope this helps :)

Given triangle is equilateral since all three angles marked as congruent.
It means each interior angle measures 60°.
The angle (5x + 15)° is exterior angle.
We know exterior angle measure is same as the sum of non-adjacent interior angles:
5x + 15 = 60 + 605x + 15 = 1205x = 120 - 155x = 105x = 105/5x = 216.
Which of the following describes the parabola with the equation y = 4x^2 − 12x + 9?
A. The axis of symmetry is x = 4 and the vertex is (4, −12).
B. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 36).
C. The axis of symmetry is x = 0 and the vertex is (0, 9).
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Answer:
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Step-by-step explanation:
y=4x^2-12x+9:\quad \mathrm{Parabola\:with\:vertex\:at}\:\left(h,\:k\right)=\left(\frac{3}{2},\:0\right),\:\mathrm{and\:focal\:length}\:|p|=\frac{1}{16}
To find the vertex of this parabola, "complete the square:" Rewrite y = 4x2 - 12x + 9 in the form y = 4(x - h)^2 + k:
y = 4x^2 - 12x + 9 => y = 4(x^2 - 3x) + 9.
Now complete the square of x^2 - 3x: Take half of -3 and square the result, obtaining (-3/2)^2, or 9/4. Add 9/4 to x^2 - 3x and then subtract 9/4 from the result: We get x^2 - 3x + 9/4 - 9/4. Substitute this result back into
y = 4(x^2 - 3x) + 9: y = 4(x^2 - 3x + 9/4 - 9/4) + 9
and then rewrite the perfect square x^2 - 3 + 9/4 as the square of a binomial:
y = 4(x - 3/2)^2 - 9/4) + 9. This simplifies to:
y = 4(x - 3/2)^2 + 0.
Thus, the vertex is at (3/2, 0) and the axis of symmetry is x = 3/2. This agrees with Answer B.
Given : equation y = 4x^2 − 12x + 9
To Find :
A) The axis of symmetry is x = 0 and the vertex is (0,9).
B)The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
C)The axis of symmetry is x = 4 and the vertex is (4, -12).
D)The axis of symmetry is x = -1.5 and the vertex is (-1.5, 36).
Solution:
y = 4x² - 12x + 9
=> y = (2x)² - 2(2x)3 + 3²
=> y = (2x - 3)²
=> y = 4(x - 3/2)²
=> y = 4(x - 1.5)²
Axis of symmetry is x= 1.5
Vertex = (1.5 , 0)
The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
For the piecewise defined function f (x)=
3x-1 x<3
1/2 x + 7. x>3
what is the following is the value of f (6) ?
Answer:
10
Step-by-step explanation:
f(x)=f(6) means x=6
Now, as 6>3 we use the formula for x>3
Substituting 6 into 1/2x+7 we get,
1/2(6)+7
=3+7
=10
The value of function at x= 6 is 10.
What is Piecewise function?A piecewise-defined function in mathematics is one that is composed of several smaller functions, each of which has a certain interval of the domain it applies to. Instead of being a property of the function itself, piecewise definition is a means to express the function.
We have,
f(x) = 3x -1 , x<3
1/2x + 7, x>3
Now, for x = 6 which falls in condition x>3
f(6) = 1/2(6)+ 7
f(6) = 3 + 7
f(6)= 10
