Write a system of inequalities to describe the
shaded region.
Answers
Answer:
In Explanation.
Step-by-step explanation:
In situations like this, you want to first find the equations of the individual lines.
Let's start with the left one.
It has a negative slope of 2 while it has a y-intercept of 1
y=-2x+1
is the equation.
The other line has a slope of 3/2.
The y-intercept is not visible, so we need to use point slope form.
I chose (2,-3)
y+3=3/2(x-2)
Simplify.
y=3x/2-3-3
y=3x/2-6
so we have
y=-2x+1
and
y=\(\frac{3x}{2}\)-6
Since both lines are solid, the signs are ≥ or ≤
The shadings intersect above both lines so the individual shadings also have to be above the line.
That means the equation is less than the "y".
y≥-2x+1
y≥\(\frac{3x}{2}\)-6

Derive the equation of the parabola with a focus at (6, 2) and a directrix of y = 1.
Answers
The equation of the parabola with a focus at (6, 2) and a directrix of y = 1 is x^2 - 12x - 2y + 39 = 0.
What id parabola?
A parabola is a mirror-symmetrical, approximately U-shaped plane curve in mathematics. It corresponds to a number of mathematical models that appear to be superficially dissimilar but which all define the exact same curves.
Given that, focus at (6, 2) and a directrix of y = 1.
Let us suppose that there is a point (x, y) on the parabola.
Its distance from the focus point (6, 2) is √(x - 6)^2 + (y - 2)^2
Its distance from directrix y = 1 is |y - 1|.
Therefore, the equation will be:
√(x - 6)^2 + (y - 2)^2 = |y - 1|
Squaring both sides.
(x - 6)^2 + (y - 2)^2 = (y - 1)^2
x^2 - 12x + 36 + y^2 - 4y + 4 = y^2 - 2y + 1
x^2 - 12x - 2y + 39 = 0
Hence, the equation of the parabola with a focus at (6, 2) and a directrix of y = 1 is x^2 - 12x - 2y + 39 = 0.

Your gross income is $4,520.00/month. Your deductions are FICA (7.65%), federal tax withholding (11.75%), and state tax withholding (8.5%). Your fixed expenses are 30% of your realized income. You saved 5 months' worth in an emergency fund, placing 75% in a 60-day CD at a 5.25% APR and the rest in a regular savings account at a 3.8% APR. What is the total amount of your emergency fund?

Answers
Answer:
(a) $4,888.40
Step-by-step explanation:
Your deductions total ...
7.65% +11.75% +8.5% = 27.9%
of your gross income. That means your realized income is ...
$4,520.00 × (1 -0.279) = $3258.92
Your monthly expenses are 30% of this amount, and your savings is 5 times your expenses. Your total savings is ...
$3258.92 × 0.30 × 5 = $4888.38 . . . . . matches choice A

C) 0.25
D) 0.667
Answers
The calculated value of the probability of B is (c) 0.25
How to calculate the probability of BFrom the question, we have the following parameters that can be used in our computation:
P(A or B) = 0.3
P(A and B) = 0.2
P(A/B) =0.8
First, we have
P(A/B) = P(A and B)/P(B)
Substitute the known values in the above equation, so, we have the following representation
0.2/P(B) = 0.8
So, we have
P(B) = 0.2/0.8
Evaluate
P(B) = 0.25
Hence, the probability of B is 0.25

Answers
A∩B={3,5,7,9}
1) In this question, we are going to find the set A intersection B, so let's pick the common numbers within the set A and B and write them as A∩B.
2) Note the following sets:
A={1,2,3,4,5,6,7,8,9,10}
B={3,5,7,9,11,13}
Let's bold the numbers that are simultaneously at A and B
A={1,2,3,4,5,6,7,8,9,10}
B={3,5,7,9,11,13}
3) Thus we can write A∩B as A∩B={3,5,7,9}

hondise totaling
Answers
Answer:
the profit percentage based on the cost & selling price is 16.67% and 14.29% respectively
Step-by-step explanation:
The computation of the profit percentage based on the cost & selling price is shown below:
The Profit percentage on the cost is
= (Sale price - cost price) ÷ (cost price) × 100
= ($175 - $150) ÷ ($150) × 100
= 16.67%
ANd, the profit percentage based on the selling price is
= (Sale price - cost price) ÷ (selling price) × 100
= ($175 - $150) ÷ ($175) × 100
= 14.29%
Hence, the profit percentage based on the cost & selling price is 16.67% and 14.29% respectively

A firm manufactured 1000 Tv sets during its first year.the total firms production during the 10 year of operationis 29035 sets .
For each the level of output for 15th year using per year constant increase in production .
Answers
Answer:
6922 TV sets
Step-by-step explanation:
You want the production in the 15th year if production in the first year is 1000 and it increases yearly by a constant amount. The total production in the first 10 years is 29035.
Arithmetic seriesAn arithmetic series is one that has a constant difference from one term to the next. If a1 is the first term of the series, and d is the common difference between terms, the n-th term is ...
an = a1 +d(n -1)
And the sum of n terms is ...
Sn = (2a1 +d(n-1))(n/2)
ApplicationTo find the 15th term, we can make use of the given values to find the common difference, then use the formula for the n-th term.
S10 = (2(1000) +d(10 -1))(10/2) . . . . . sum formula with a1=1000
29035 = 10000 +45d . . . . . . . . . . . simplified
d = (29035 -10000)/45 = 423 . . . . the increase in production each year
Production in the 15th year is ...
a15 = 1000 +423(15 -1) = 1000 + 5922 = 6922
The output in the 15th year was 6922 TV sets.

f ( 2 x + 1 ) = 6 x − 2
Step-by-step explanation:
Set up the composite result function.
f ( g ( x ) )
Evaluate f ( g ( x ) )
by substituting in the value of g into f
. f ( 2 x + 1 ) = 3 ( 2 x + 1 ) − 5
Simplify each term.
Apply the distributive property.
f ( 2 x + 1 ) = 3 ( 2 x )+ 3 ⋅ 1 − 5
Multiply 2 by 3 .
f ( 2 x + 1 ) = 6 x + 3 ⋅ 1 − 5
Multiply 3 by 1 .
f ( 2 x + 1 ) = 6 x + 3 − 5
Subtract 5 from 3 . f ( 2 x +1 ) = 6 x− 2
