Step-by-step explanation:

Data

Money made $242 / 11 h

Money made $154 / ?

Process 1

1.- Determine the money made in one hour using proportions and cross multiplication

                       $242------------------------ 11 h

                            x   ------------------------  1 h

                                x = (1 x 242)/11

                                x = $22

2.- Use proportions to determine the hours he work to made $154

                        $22 --------------------  1 h

                      $154 -------------------- x

                              x = (154 x 1) / 22

                              x = 154/22

                             x = 7 hours

Answer:

A) 9

Step-by-step explanation:

  15 - 3(6 - 4)

= 15 - 3(2)

= 15 - 3 x 2

= 15 - 6

= 9

The given expression is equivalent to 9 The correct answer is option A) 9.

To simplify 15 - 3(6 - 4), we follow the order of operations (PEMDAS/BODMAS):

Step 1: Start with the innermost parentheses (6 - 4):

15 - 3(2)

Step 2: Next, perform the multiplication:

15 - 6

Step 3: Finally, do the subtraction:

9

The correct answer is option A) 9. The explanation shows how we first evaluate the expression inside the parentheses (6 - 4), then perform the multiplication (3 times 2), and finally subtract the result (6) from the initial value (15) to get the final answer of 9.

Answer:

k = 1

Step-by-step explanation:

English Translation

Find k if the point P (-1, 2k + 1) belongs to the graph of the function f (x) = - 4x^2 + 7.

The function is given as

y = f(x) = -4x² + 7

and point (-1, 2k+1) lies on the graph.

This point means that, at x = -1, y = 2k+1

y = -4x² + 7

Substituting the values in

2k + 1 = -4(-1)² + 7

2k + 1 = -4 + 7 = 3

2k = 3 - 1

2k = 2

k = 1

Hence, the point (-1, 2k+1) is (-1, 3)

To check,

y = -4x² + 7

3 = -4(-1)² + 7

3 = -4 + 7

3 = 3

So, this is truly correct.

Answer: A) x2+y2+16x-8y+73=0

Step-by-step explanation:

I got it right on edge.

The generic version of the circle equation is, x² + y² + 16x - 8y + 73 = 0.

A circle is a closed two-dimensional object in which all points in the plane are equidistant from a single point known as the "centre." The line of reflection symmetry is formed by every line that travels through the circle. For any angle, it also exhibits rotational symmetry around the center.

Step 1:

The conventional form of the circle equation is expressed as:

(x - a)² + (y - b)² = r²

where centers are specified as (a,b)

The circle equation given in the question is:

x² + y² = 7

If the circle is translated T(-8,4), the center of the translated circle is located at (-8,4).

As a result, the conventional version of the circle equation is:

(x + 8) ² + (y - 4) ² = 7

Step 2:

Simplifying the problem:

(x² + 64 + 2(x)(8)) + (y² + 16 - 2(y)(4)) = 7

x² + 64 + 16x + y² + 16 - 8y = 7

x² + y² + 16x - 8y + 80 = 7

x² + y² + 16x - 8y + 80 - 7 = 0

x² + y² + 16x - 8y + 73 = 0

which is the generic version of the circle equation.

Given:

A rectangular wall with 2 windows and a 1 door.

To find:

The area of the wall and the amount of paint required to cover the wall.

Solution:

The area of the wall can be determined by subtracting the areas covered by the windows and the door from the area of the entire wall.

The entire wall has a length of 12 feet and a width of 8 feet.

The area of a rectangle [tex]=(l)(w).[/tex]

The area of a square [tex]= a^{2} .[/tex]

The entire wall's area [tex]= (12)(8)= 96[/tex] square feet.

The door has a length of 3 feet and a width of 6 feet.

The area of the door [tex]=(3)(6)=18[/tex] square feet.

The windows are in the shape of a square.

The side length of the windows is 2 feet.

The area of a window [tex]= 2^{2} =4[/tex] square feet.

The area of 2 windows [tex]= 2(4) = 8[/tex] square feet.

The area of the wall [tex]=96-18-8=70[/tex] square feet.

If a quart of extra-thick exterior paint covers 30 square feet, then 70 square feet will need;

The paint needed to cover 70 square feet [tex]= \frac{70}{30} = 2.333[/tex] quarts.

So the area of the wall was 70 square feet and 2.333 quarts of extra-thick exterior paint is required to cover the wall.

Answer:

32 degrees

Step-by-step explanation:

The interior and exterior of X must equal 180 degrees.

X + W = 180

Plug in 100 for W and subtract it from both sides.

180 - 100 = X = 80 degrees.

The total of the internal angles of a triangle are 180 degrees.

80 + 68 + Y = 180

Solve for Y:  Y = 180 - 68 - 80 = 32 degrees.

The sequence is a function

Step-by-step explanation:

where n is the number of months since his initial deposits, and A₀=50

The sequence is a function because its domain is a set of natural numbers.

For example,

A₁=A₀+25 =75

A₂=A₁+25=100

A₃=A₂+25=125

A₄=A₃+25=150

The domain is 0, 1, 2, 3, 4, 5,.....

The set of all non-negative integers.

Given sequence is [tex]A_{0}=50, \ A_{n}=A_{n-1}+25[/tex]

Domain of this sequence is n = the number of months since the initial deposit.

The possible values of n = 0, 1, 2, 3, 4, 5,..... It means the set of all non-negative integers.

So it is the domain of the sequence.

Answer:

The area of the rectangular area is (1400w-w²) square yards.

Step-by-step explanation:

Given that,

David has available 2800 yards of fencing. He wants to enclose a rectangular area.

Assume that, the length and width of the rectangular be l and w  respectively.

The perimeter of the rectangular area is

=2(length+ width)

=2(l+w)

So,

2(l+w)= 2800

[tex]\Rightarrow l+w= \frac{2800}{2}[/tex]

[tex]\Rightarrow l+w= 1400[/tex]

[tex]\therefore l= 1400-w[/tex]

The area of the rectangular area is = length× width

                                                            =l×w

                                                           =(1400-w) w

                                                           =(1400w-w²) square yards.

Final answer:

The area A of the rectangle can be expressed as a function of the width W by using the equation 2L + 2W = 2800, where L represents the length of the rectangle. The formula for the area of a rectangle is A = L * W, substituting the value of L in terms of W, we get A = ((2800 - 2W)/2) * W.

Explanation:

To express the area A of the rectangle as a function of the width W, we need to understand that a rectangle has two equal lengths and two equal widths. Let's assume the length of the rectangle is L. Since the perimeter of the rectangle is 2800 yards, we can write the equation: 2L + 2W = 2800.

Now, we can express L in terms of W: L = (2800 - 2W)/2. The area of the rectangle is given by the formula A = L * W. Substituting the value of L, we get A = ((2800 - 2W)/2) * W.

This is the function that expresses the area A as a function of the width W.

Quarterly Rate means the per annum interest rate to be determined for the Bonds on a quarterly basis and the quarterly rate of population increase [tex]0.00447[/tex].

What is quarterly?

If the rate of interest is annual and the interest is compounded quarterly then the number of years [tex](n)[/tex]  is  [tex]4 times[/tex]  and the rate of annual interest [tex](r)[/tex] is one-fourth.

Here given that the annual rate is [tex]r=0.018[/tex].

And the exponential growth function is

[tex]y=a(1+r)^{x} ...(1)[/tex]

where [tex]a[/tex] is the initial amount

and  [tex]r[/tex] is the rate of growth.

So, By equation [tex](1)[/tex], we get

[tex]y=a(1+0.018)^{t}\\y=a(1.018)^{t}[/tex]

The quarterly growth rate, the exponent is the number of quarters in [tex]t years[/tex] or [tex]4t[/tex].

So, by multiplying the exponent by [tex]\frac{4}{4}[/tex], the [tex]4t[/tex] represents the number of quarters

[tex]i.e., y=a(1.018)^\frac{4t}{4}\\y=a(1.018^\frac{1}{4})^{4t}\\y=a(1.00447)^{4t}\\[/tex]

Hence, the quarterly growth rate is [tex]1.00446[/tex], now we subtract it with [tex]1[/tex] so it is of the form:-

[tex]1.004477-1=0.00447[/tex]

which implies that the population is increasing.
