Which ordered pair maximizes the objective function p=3x+8y
(0,0)
(2,7)
(5,6)
(8,1)
Answer:
P(5,6) = 63
Step-by-step explanation:
Test each point to see which ordered pair maximizes the objective function:
(0,0): p = 3(0) + 8(0) = 0
(2,7): p = 3(2) + 8(7) = 6 + 56 = 62
(5,6): p = 3(5) + 8(6) = 15 + 48 = 63
(8,1): p = 3(8) + 8(1) = 24 + 8 = 32
Hence, (5,6) is the ordered pair that maximizes the objective function.

26 ÷ 7.5 ≈ 3.47 ( to 2 decimal places )
then dimensions are approximately 1.73 inches by 3.47 inches
Which expression is equivalent to 3m+1-m?
A-2+m-1+m
B-1+m
C-3m-1
D-3m
Answer:
A
Step-by-step explanation:
Answer:
option (a) is correct.
2 + m - 1 + m is an equivalent expression to the given expression 3m+1-m
Step-by-step explanation:
Given expression 3m+1-m
We have to choose an equivalent expression from given options.
Equivalent expression are those expression that looks different but are same.
Like 4+2 = 6 and 3+ 3 = 6
Both have same value but looks differently.
Like terms are term having same variable with same degree.
Consider the given expression 3m+1-m
Simplify by adding like terms,
3m + 1 - m = (3-1) m + 1
Thus, (3-1) m + 1 = 2m + 1
Also 2m + 1 can be written as m + m + 2 - 1
Thus, option (a) is correct.

y = - x - 10 → (1)
x² + y - 2 = 0 → (2)
substitute y = - x - 10 into (2)
x² - x - 10 - 2 = 0
x² - x - 12 = 0 ← in standard form

Thirteen out of the 147 randomly selected faculty members who were surveyed at a community college know sign language. Construct and interpret a 90% confidence interval for the proportion of all faculty members at the community college who know sign language.
The 90% confidence interval for the proportion of all faculty members at the community college who know sign language is (0.0420, 0.1348)
We can use the formula for a confidence interval for a proportion to calculate the interval
CI = p ± zsqrt(p(1-p)/n)
where:
p is the sample proportion (13/147 = 0.0884)
z is the z-score for the desired confidence level (90% confidence level corresponds to a z-score of 1.645)
n is the sample size (147)
Substituting the values, we get
CI = 0.0884 ± 1.645sqrt(0.0884(1-0.0884)/147)
Simplifying the expression, we get
CI = 0.0884 ± 0.0464
Therefore, the 90% confidence interval for the proportion of all faculty members at the community college who know sign language is
CI = (0.0420, 0.1348)

Malcolm has $50 gift card to a local car wash and order is the ultimate car wash each visit is $8.95
The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.
The correct answer choice is option B.
How much cheaper is the car washes Malcolm orders than the car washes Martha's order?Malcolm's gift card = $50.
Cost Malcolm's car wash per visit = $7
Martha's gift card = $180
Cost Martha's car wash per visit = Difference between gift card balance of first and second visit
= $180 - $160
= $20
How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7
= $13
Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

the largest orange in a bag has the circumference of 9 5/8 inches. The smallest orange has a circumference
of 7 13/16 inches. Write the difference of the circumferences of the smallest orange and the largest orange
Answer:
1.81 inches
Step-by-step explanation:
Given that,
The circumference of the largest orange in a bag is \(9\dfrac{5}{8}\ \text{inches}\) and that of smallest orange is \(7\dfrac{13}{16}\ \text{inches}\).
Difference = largest orange - smallest orange
= \(9\dfrac{5}{8}-7\dfrac{13}{16}\\\\=\dfrac{77}{8}-\dfrac{125}{16}\\\\=\dfrac{29}{16}\\\\=1.81\ \text{inches}\)
So, difference of the circumferences of the smallest orange and the largest orange is 1.81 inches
7. Kelly developed a formula for using a computer to find for a specific quote within a large set of articles.
The following function gives the length of the search, in seconds, over a set of n articles.
S(n) = 1.6 In (0.8n). What is the instantaneous rate of change of the search length for a set of 12 article:
Use correct units to explain the meaning of the answer.
instantaneous rate of change of the search length 0.1667 seconds per
How to find the instantaneous rate of change?We need to take the derivative of the function S(n) with respect to n and evaluate it at n=12 in order to determine the instantaneous rate of change of the search length for a set of 12 articles.
Taking the derivative of S(n) with respect to n using the chain rule, we get:
S'(n) = 1.6 * (1/(0.8n)) * 0.8 = 2/n
Evaluating this expression at n=12, we get:
S'(12) = 2/12 = 0.1667 seconds per article
This indicates that the search time will increase by approximately 0.1667 seconds per article if the set contains 12 articles by one unit. Alternately, the search time per article will decrease by approximately 0.1667 seconds if the set's number of articles decreases by one unit from 12.
Therefore, the units for the instantaneous rate of change are "seconds per article", indicating the change in search time for each additional or fewer article in the set.

Note that the parameters of the graph a and graph b are given below.
Graph A - y=2(x-1)²
See graph attached.
Graph B - y = 1/2x² + 3
Vertex: The vertex of the function is (0, 3).
Axis of symmetry: The axis of symmetry is the vertical line passing through the vertex, which is x = 0.
Y-intercept: The y-intercept is the point where the graph intersects the y-axis. It is (0, 3).
Minimum or maximum: The coefficient of x² is positive, which means the parabola opens upwards, and therefore the function has a minimum value. The minimum value is 3.
Solutions: To find the solutions or roots of the quadratic equation, we need to set y or f(x) equal to zero and solve for x.
0 = 1/2 x² + 3
Subtracting 3 from both sides, we get:
-3 = 1/2 x²
Multiplying both sides by -2, we get:
6 = -x²
Taking the square root of both sides, we get:
x = ±√(-6)
Since the square root of a negative number is not a real number, the function has no real roots.
Minimum or maximum value: The minimum value of the function is 3.
Range: The range of the function is y ≥ 3, because the function has a minimum value of 3.
Domain: The domain of the function is all real numbers, because there are no restrictions on the values of x for which the function is defined.
Stretch/Shrink/Standard: The coefficient of x^2 is positive and less than 1, which means that the graph of the function is narrower than the graph of y = x². This is an example of a standard quadratic function that has been vertically compressed by a factor of 1/2.

VOR
The position of the helicopter and the two VORs forms a triangle and the third angle formed by these three entities is 40 degrees
The diagram is not shown; however, the question can still be answered.
The given angles are:
\(\theta_1 = 74.0^o\)
\(\theta_2 = 66.0^o\)
Represent the third angle as \(\theta_3\)
The helicopter and the 2 VORs form a triangle.
So, we make use of the following theorem to calculate the third angle
\(\theta_1 + \theta_2 + \theta_3= 180^o\) ---- sum of angles in a triangle
Substitute known values
\(74.0^o + 66.0^o + \theta_3= 180^o\)
\(140.0^o + \theta_3= 180^o\)
Collect like terms
\(\theta_3= 180 -140.0^o\)
\(\theta_3= 40^o\)
Hence, the third angle is 40 degrees.

Rectangle A, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-6, -4), B(-4,-4), C(-4, -2), and D(-6, -2). What is the perimeter of rectangle A, B, C, D?
Answer:
Perimeter of rectangle ABCD = 9.64 units
Step-by-step explanation:
The formula used to calculate perimeter of rectangle is:
\(Perimeter\: of\: rectangle=2(Length+ Width)\)
We know that rectangle has opposite sides same i.e Length (AB and CD) are same and Width( AD and BD) are same
We need to find Length and Width to find the perimeter
So, if we find Length AB and Width AC we can find perimeter
Finding Length AB
The length AB can be found using distance formula: \(Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
We have A =(-6,-4) and B(-4,-4)
So, x_1=-6, y_1=-4, x_2=-4, y_2=-4
Putting values in formula and finding length
\(Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-4-(-6))^2+(-4-(-4))^2}\\Distance=\sqrt{(-4+6)^2+(-4+4)^2}\\Distance=\sqrt{(2)^2+(0)^2}\\Distance=\sqrt{4+0}\\Distance = 2\)
So, Length AB = 2
Now, Finding Width AC
The length AB can be found using distance formula: \(Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
We have A =(-6,-4) and C(-4,-2)
So, x_1=-6, y_1=-4, x_2=-4, y_2=-2
Putting values in formula and finding length
\(Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-6-(-4))^2+(-4-(-2))^2}\\Distance=\sqrt{(-6+4)^2+(-4+2)^2}\\Distance=\sqrt{(-2)^2+(-2)^2}\\Distance=\sqrt{4+4}\\Distance = \sqrt{8}\\Distance=2.82\)
So, Width AD = 2.82
Now, We have Length = 2 and Width = 2.82
Finding perimeter of rectangle
\(Perimeter\: of\: rectangle=2(Length+ Width)\\Perimeter\: of\: rectangle=2(2+ 2.82)\\Perimeter\: of\: rectangle=2(4.82)\\Perimeter\: of\: rectangle=9.64\)
So, Perimeter of rectangle ABCD = 9.64 units
