Answer:
D. x = -7/3
Step-by-step explanation:
A graphical solution is often easier when the problem is written in the form f(x) = 0. That way, the x-intercept(s) of the function f(x) will be the solution.
F(x) = 0The desired form can be found by subtracting 16 from both sides of the equation:
[tex]\left(\dfrac{1}{64}\right)^{-x-3}=16\qquad\text{given}\\\\\left(\dfrac{1}{64}\right)^{-x-3}-16=0\quad\Longrightarrow\quad f(x)=\left(\dfrac{1}{64}\right)^{-x-3}-16[/tex]
A graph is attached, showing x=-7/3 is the solution.
Algebraic solutionUsing powers of 4, the equation can be rewritten ...
[tex]\left(\dfrac{1}{4^3}\right)^{-x-3}=4^2\qquad\text{given}\\\\4^{3(x+3)}=4^2\\\\3(x+3)=2\qquad\text{equating exponents, or taking base-4 logs}\\\\x=\dfrac{2}{3}-3=\boxed{-\dfrac{7}{3}}\qquad\text{divide by 3, subtract 3}[/tex]

For Pharaoh Company, variable costs are 60% of sales,the fixed costs are $175,500. Managements net income goal is $67,500.
The required sales in dollars needed to achieve managements target is $607,5000.
What is the required level of sales?
Net income is total revenue less total cost. Total cost is the sum of fixed cost and variable cost. Fixed cost is the cost that remains constant regardless of the level of output. e.g. rent. Variable cost is the cost that varies with output e.g. wages.
Net income = sales - total cost
Net income = sales - (fixed cost + variable cost)
$67,500 = sales - ($175,500 + 0.6sales)
$67,500 = sales - $175,500 - 0.6sales
$67,500 + $175,500 = sales - 0.6sales
243,000 = 0.4sales
sales = 243,000 / 0.4
sales = $607,500
Here is the complete question:

The graph shows a system of inequalities. Graph of two inequalities. One is a solid line increasing from left to right passing through negative 3 comma 0 and 0 comma 3, and it has shading below the line. The second is a solid upward opening parabola with a vertex at 1 comma negative 4 and x-intercepts at negative 1 comma 0 and 3 comma 0. This parabola is shaded inside the curve. Which system is represented in the graph? y > x2 –2x – 3 y > x + 3 y < x2 – 2x – 3 y < x + 3 y ≥ x2 – 2x – 3 y ≤ x + 3 y > x2 – 2x – 3 y < x + 3
The inequalities in the system of inequalities are y > x² – 2x – 3 and y > 3x + 4
How to determine the system of inequalities?The graph that completes the question is added as an attachment
The parabola
It has a vertex of (1, -4)
So, we have:
y = a(x - 1)^2 - 4
It passes through (3, 0).
So, we have:
0 = a(3 - 1)^2 - 4
This gives
4a - 4 = 0
Solve for a
a = 1
Substitute a = 1 in y = a(x - 1)^2 - 4
y = (x - 1)^2 - 4
Expand
y = x^2 - 2x + 1 - 4
y = x^2 - 2x - 3
The inner part is shaded.
So, we have:
y > x^2 - 2x - 3
The linear equation
It passes through (0, 4).
So, we have:
y = mx + 4
It passes through (1, 7).
So, we have:
7 = m + 4
Solve for m
m = 3
Substitute m = 3 in y = mx + 4
y = 3x + 4
The upper part is shaded.
So, we have:
y > 3x + 4
Hence, the inequalities in the system of inequalities are y > x² – 2x – 3 and y > 3x + 4

C) P(J or 8) = 2/13
D) P(H or S) = 1/2
E) P(R and F) = 3/26
F) P(R or Q) = 7/13
What is probability?The ratio of favorable outcomes to the total outcomes of an event is said to be its probability.
P(E) = n(E)/n(S)
Calculation:It is given that a single card is drawn at random from a standard deck of 52 cards.
So, the sample space consists of 52 cards in total
From those,
4 suits: Hearts, Clubs, Spades, Diamonds
Each of the suit has 13 cards: { Ace, 2,3,4,5,6,7,8,9,10, Jack, Queen, King}
There are 26 Red cards and 26 Black cards.
A) The probability of drawing a diamond or a 5:
P(D or 5) = P(D) + P(5) - P(D and 5)
= 13/52 + 4/52 - 1/52
= 16/52 = 4/13
B) The probability of drawing a heart and a jack:
P(H and J) = P(H) × P(J) (Since they are independent events)
= 13/52 × 4/13
= 1/13
C) The probability of drawing a jack or 8:
P(J or 8) = P(J) + P(8) - P(J and 8)
= 4/52 + 4/52 - 0
= 2/13
D) The probability of drawing a heart or a spade:
P(H or S) = P(H) + P(S) - P(H and S)
= 13/52 + 13/52 - 0
= 26/52 = 1/2
E) The probability of drawing a red and face card:
P(R and F) = P(R) × P(F) (Since they are independent)
= 26/52 × 12/52
= 1/2 × 3/13
= 3/26
(There are three face cards- jack, king, and queen: each of 4)
F) The probability of drawing a red card or a queen:
P(R or Q) = P(R) + P(Q) -P(R and Q)
= 26/52 + 4/52 - 2/52
= 28/52 = 7/13

The given parameters are:
∠KPL = 46°
∠NPH = 25°
∠MPN = ∠NPH
By vertical angle theorem, we have:
∠JPK = ∠MPH
Where
∠MPH = ∠MPN + ∠NPH
This gives
∠MPH = ∠NPH + ∠NPH
So, we have:
∠MPH = 25° + 25°
Evaluate
∠MPH = 50°
Recall that:
∠JPK = ∠MPH
So, we have:
∠JPK = 50°
Hence, the measure of angle ∠JPK is 50°
Angle LPM
The angle on a straight line is 180°.
So, we have:
∠LPM + ∠KPL + ∠MPH = 180°
This gives
∠LPM + 46° + 50° = 180°
Evaluate
∠LPM = 84°
Hence, the measure of angle ∠LPM is 84°
Angle NPM
In (a), we have:
∠NPM = ∠NPH
This gives
∠NPM = 50°
Hence, the measure of angle ∠NPM is 50°
Angle JPI
By vertical angle theorem, we have:
∠JPI = ∠LPM
So, we have:
∠JPI = 84°
Hence, the measure of angle ∠JPI is 84°

Given that BD is diameter of the circle and angle BAC is 100°.
We are required to find the central angle, major arc, minor arc, m BEC, BC.
Angle is basically finding out the intensity of inclination of something on the surface.
In the circle central angles are many like BAC and CAD. We can write CAD as DAC also.
Major arc of a circle is that arc whose length is larger than all other arcs in the circle.
In our circle the major arc is arc BED.
Minor arc of a circle is that arc whose length is smaller.
In our circle the minor arc is arc ADC.
We know that arc's length is 2πr(Θ/360)
In this way BC=2π*(BD/2)*100/360

well, keeping in mind that a year has 365 years, so let's see
[tex]\stackrel{Oct}{10}~~ + ~~\stackrel{Nov}{30}~~ + ~~\stackrel{Dec}{31}~~ + ~~\stackrel{Jan}{31}~~ + ~~\stackrel{Feb}{21}\implies 123~days[/tex]

7.8% is the simple interest rate was charged if Robin repaid $3,694.63.
What is simple InterestSimple interest is based on the principal amount of a loan or the first deposit in a savings account.
A=P(1+rt)
A is final amount, P is principle amount, r is rate of interest and t is time.
We know that in a year we have 365 days.
But the time here is from oct 21 to feb 21, which has 123 days.
so the 3600 were borrowed for only 123 days of a year, that'd be 123/365 of a year, thus
Apply these values in formula
A=P(1+rt)
3694.63=3600(1+r/100(123/365))
3694.63=3600(1+123r/36500)
3694.63/3600=1+123r/36500

2. What is the 7th term of an A.P: 50+45+40? a. 40, b. 20, c. 15, d. 22
The 7th term of an Arithmetic Progression 50+45+40 is 20
How to determine the 7th term of an Arithmetic Progression 50+45+40?The Arithmetic Progression is given as:
50+45+40
In the above Arithmetic Progression, we have
First term, a= 50
Common difference, d = 45 - 50 = -5
The nth term of the Arithmetic Progression is calculated as:
Tn = a + (n - 1)d
Substitute the known values in the above equation
Tn = 50 + (n - 1) * -5
Substitute 7 for n in the above equation
Tn = 50 + (7 - 1) * -5
Evaluate the product
Tn = 50 - 30
Evaluate the difference
T7 = 20
Hence, the 7th term of an Arithmetic Progression 50+45+40 is 20

Scenario 2 You are at a restaurant with three friends (party of 4) and need to estimate the amount of tip for your portion of the bill without using a calculator. Assume a 20% tip rate. For full credit, you will need the cost of your meal, an explanation of how you would calculate your 20% tip, and the total amount. Part B: Explain how you would solve this problem by organizing a sample calculation.
Assuming you had a bill of $120 when you went to the restaurant with your three friends, the 20% tip would come out to $24.
What would be the tip?First assume an amount that the meal you ate cost. Let's assume that amount if $120.
If the tip rate if 20%, it means that you need to find out what 20% of the bill of $120 is.
If you don't want to use a calculator, there are other ways you can calculate the tip.
An easy method would be to find 10% of the bill. To find 10%, all you have to do is to move the decimal point from right to left.
The decimal point in $120 is at the far right so the 10% amount would be:
= $12.0
Now that you have the 10% amount, remember that 20% is simply twice the amount of 10% so:
= 12 x 2
= $24
The total amount then becomes:
= 120 + 24
= $144
In conclusion, your tip amount would be $24.

Consider the function f(x)=x
Describe the transformation of g(x)=2f(x-4)+2
The parent function ____ will undergo ____ transformations. The first transformation is a _____ reflect by a factor of ______. Next, the graph will shift ______ units to the ______. Finally, the graph will shift _____ units ____.
Please help me!
The parent function f(x) = x will undergo 3 transformations. The first transformation is vertically stretched by a factor of 2. Next, the graph will shift 4 units to the right. Finally, the graph will shift 2 units up
How to determine the transformation?The function is given as:
f(x) = x
This represents the parent function.
Start by stretching the function vertically by a factor of 2
This gives
f'(x) = 2x
Next, we shift the graph 4 units to the right
This gives
f''(x) = 2(x - 4)
Finally, we shift the graph 2 units up
This gives
f'''(x) = 2(x - 4) + 2
The number of transformations above is 3
Hence, the complete statement is:
The parent function f(x) = x will undergo 3 transformations. The first transformation is vertically stretched by a factor of 2. Next, the graph will shift 4 units to the right. Finally, the graph will shift 2 units up
