Answer:
They will be picked up at 2 [tex]\frac{1}{4}[/tex] yards above sea level
Step-by-step explanation:
Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.
With respect to this reference,
the position of top most point is +17 [tex]\frac{3}{4}[/tex] yards
and the position of lower most point is -13 [tex]\frac{1}{4}[/tex] yards
⇒ The position of midpoint is [tex]\frac{+17 \frac{3}{4} - 13 \frac{1}{4}}{2}[/tex]
= +2 [tex]\frac{1}{4}[/tex]
∴ They will be picked up at 2 [tex]\frac{1}{4}[/tex] yards above sea level

Step-by-step explanation:
A manufacturer of tennis rackets makes a profit of $15 on each oversized racket and $8 on each standard racket. To meet dealer demand, daily production of standard rackets should be between 30 and 80, and production of oversized rackets should be between 10 and 30. To maintain high quality, the total number of rackets produced should not exceed 80 per day. How many of each type should be manufactured daily to maximize profit?
Answer:
30 oversized rackets and 50 standard rackets
Step-by-step explanation:
To maximize profit, it is very essential she strikes a balance between the two type of rackets. It is important to note that the profit on oversized racket is twice that of standard racket. Hence, she must make as many oversized rackets as possible.
The highest number of oversized racket she can make is 30. Subtracting 30 from the total number of rackets give 50 standard racket
To maximize profit, represent the constraints as a system of inequalities, graph these to find a feasible region, and evaluate the profit function at each vertex of this region.
Explanation:Maximizing Profit with Production ConstraintsTo determine how many of each type of tennis racket a manufacturer should produce daily to maximize profit, we can set up a system of inequalities based on the given constraints and then use linear programming. The constraints are that the daily production of standard rackets (S) should be between 30 and 80, and production of oversized rackets (O) should be between 10 and 30. Additionally, the total number of rackets produced (S + O) should not exceed 80 per day.
The profit function to be maximized is P = 15O + 8S. The optimization process involves graphing the inequalities to form a feasible region, then evaluating the profit function at each vertex of this region to find the maximum profit point.
The constraints can be written as:
We look for the corner points of the feasible region that satisfies all the constraints and calculate the profit at each of these points. The highest profit among these calculated values will give us the optimal number of each type of racket to produce.
By systematically evaluating the profit P at the corner points of the feasible region, the manufacturer can identify the production levels of standard and oversized rackets that will maximize profit within the given constraints.
This approach ensures that the manufacturer can meet dealer demand, maintain high quality through production limits, and optimize profit based on the profit margins of each racket type.

solve ordinary differential equation
Answer:
y(t) = c₁ e^(-1/2 t) cos(√3/2 t) + c₂ e^(-1/2 t) sin(√3/2 t) + 1
Step-by-step explanation:
y" + y' + y = 1
This is a second order nonhomogenous differential equation with constant coefficients.
First, find the roots of the complementary solution.
y" + y' + y = 0
r² + r + 1 = 0
r = [ -1 ± √(1² − 4(1)(1)) ] / 2(1)
r = [ -1 ± √(1 − 4) ] / 2
r = -1/2 ± i√3/2
These roots are complex, so the complementary solution is:
y = c₁ e^(-1/2 t) cos(√3/2 t) + c₂ e^(-1/2 t) sin(√3/2 t)
Next, assume the particular solution has the form of the right hand side of the differential equation. In this case, a constant.
y = c
Plug this into the differential equation and use undetermined coefficients to solve:
y" + y' + y = 1
0 + 0 + c = 1
c = 1
So the total solution is:
y(t) = c₁ e^(-1/2 t) cos(√3/2 t) + c₂ e^(-1/2 t) sin(√3/2 t) + 1
To solve for c₁ and c₂, you need to be given initial conditions.

Answer:
The initial investment was $7945.58.
Step-by-step explanation:
Use the compound interest formula: A = P(1 + r)^t
A is the ending amount, in this case 11,680.
P is the starting amount, which is unknown.
r is the interest rate in decimal form, in that case 8% is 0.08.
t is the time in years, in this case 5.
Substitute known values into the equation
A = P(1 + r)^t
11,680 = P(1.08)^5
11,680 = 1.47P
P = 11,680/1.47
P = 7945.58
The initial investment was $7945.58.

a. Find a mixture that will make the same shade of green but a smaller amount.
b. Find a mixture that will make the same shade of green but a larger amount.
Findami
Answer:
a. 1 cup of yellow and 1.75 cups of blue
b. 4 cups of yellow and 7 cups of blue
Step-by-step explanation:
a. We can multiply both sides of this ratio by an number of our choice to get an equivalent ratio. 2:3.5 = 1: 1.75. (We are multiplying by 1/2)
b. 2 : 3.5 = 4 : 7 (We are multiplying by 2)

Write the quadratic equation whose roots are -5 -4 and whose leading coefficient is 4
Answer:
y = 4x² + 36x + 80
Step-by-step explanation:
Since the roots are x = - 5 and x = - 4 then the factors are
(x + 5) and (x + 4)
The equation is the product of the factors
y = (x + 5)(x + 4) and with leading coefficient of 4 is
y = 4(x + 5)(x + 4) ← expand factors
= 4(x² + 9x + 20)
= 4x² + 36x + 80

So, its a multiplying question - the product. Also there are multiple answers from x = negative anything to positive 14, so i chose a number.
The product of -2 and a number minus six is greater than -18.
-2 · (x - 6) > -18
-2 · (7 - 6) > -18
-2 · (1) > -18
-2 > -18
x = 7, or anything lower than 15.

The equations x - 3y = -4 and 2x - 6y = 6 represent a system with parallel lines that do not intersect, therefore there are no solutions to this system of equations.
Explanation:Let's solve the system of equations using the method of substitution or elimination. First, look at the two given equations:
x - 3y = -4 (Equation 1)2x - 6y = 6 (Equation 2)It's clear that Equation 2 is simply Equation 1 multiplied by 2. This implies the two equations are multiples of each other, which could mean the system has an infinite number of solutions or no solutions. Let's simplify Equation 2 to confirm:
Divide Equation 2 by 2:
2x/2 - 6y/2 = 6/2
x - 3y = 3
This new equation contradicts Equation 1 (x - 3y = -4), which indicates that there are no solutions since the two lines are parallel and will never intersect.

Complete each geometric sequence.
B. 40, 120, ___, ___
C. 200, 20, 2, ___, 0.02, ___
The missing terms in the geometric sequences are 360 and 1080 for sequence B, and 0.2 and 0.02 for sequence C.
Explanation:In this question, we're working with geometric sequences. A geometric sequence is a sequence in which you multiply by a constant to get from one term to the next.
For sequence B, we notice that 120 is three times 40, so we're multiplying by 3 each time. Thus, the next two terms would be 360 (120 * 3) and 1080 (360 * 3).
For sequence C, we're dividing by 10 to get from one term to the next (200 / 10 = 20, 20 / 10 = 2). Thus, the missing terms would be 0.2 (2 / 10) and 0.02 (0.2 / 10).

Answer:
51
Step-by-step explanation
12-9 = 3

Total number of not broken windows is 51 windows
Given that;Number of big window = 48
Number of small window = 12
Number of broken window = 9
Find:Total number of not broken windows
Computation:Total number of not broken windows = Number of big window + Number of small window - Number of broken window
Total number of not broken windows = 48+ 12 - 9
Total number of not broken windows = 60 - 9

If one inch represents 18 feet, what dimensions would you use to make a scale drawing of a building 630 feet by 450 feet?
Answer:
35 by 25 inches
Step-by-step explanation:
1 inch = 18 feet
each 18 feet in the scale model is one inch, which means that there is one inch per 18 feet, so all you need to do is divide 630 by 18 and 450 by 18.
630/18 = 35
450/18 = 25
so the dimensions of the scale model are 35 by 25 inches

total annual expenses is for product payment costs? Round to the
nearest hundredth of a percent.
Answer:
The percentage of the total annual expenses for product payment costs is 11.49% .
Step-by-step explanation:
Given:
Annually costs on product company spends = $34000 and total annual expenses = $296000.
Now, to get the percentage of the total annual expenses for product payment costs. We will calculate the percentage, $34000 by $296000:
According to question:
[tex]\frac{34000}{296000} \times 100[/tex]
[tex]=0.11486\times 100[/tex]
[tex]=11.486[/tex]
Now, rounding to the nearest hundredth of a percent to 11.486 will be 11.49. As we see 6 in the thousandth place and 8 in hundredth place so rounding to decimal in hundredth place will change 8 into 9.
Therefore, the percentage of the total annual expenses for product payment costs is 11.49% .
