Given: △ABC, CM⊥ AB, BC = 5, AB = 7
CA = 4 sqrt(2)
Find: CM
Answer:
The general plan is to find BM and from that CM. You need 2 equations to do that.
Step One
Set up the two equations.
(7 - BM)^2 + CM^2 = (4*sqrt(2) ) ^ 2 = 32
BM^2 + CM^2 = 5^2 = 25
Step Two
Subtract the two equations.
(7 - BM)^2 + CM^2 = 32
BM^2 + CM^2 = 25
(7 - BM)^2 - BM^2 = 7 (3)
Step three
Expand the left side of the new equation labeled (3)
49 - 14BM + BM^2 - BM^2 = 7
Step 4
Simplify And Solve
49 - 14BM = 7 Subtract 49 from both sides.
-49 - 14BM = 7 - 49
- 14BM = - 42 Divide by - 14
BM = -42 / - 14
BM = 3
Step Five
Find CM
CM^2 + BM^2 = 5^2
CM^2 + 3^2 = 5^2 Subtract 3^2 from both sides.
CM^2 = 25 - 9
CM^2 = 16 Take the square root of both sides.
sqrt(CM^2) = sqrt(16)
CM = 4 < Answer

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the monthly demand for widgets. WidgCo's marketing department determines that p and x are related by the following demand equation: p(x) = 211 − 5x. The cost of producing x widgets is given by C(x) = 1,401 + 16x. Construct the revenue function, R(x). Find the production level that will result in the maximum revenue. Find the maximum monthly revenue. Enter your answer to part c in the box below. Round your answer to the nearest cent.
Answer:
the revenue function = x · P(x) - C(x) = x · (211 − 5x) - (1,401 + 16x) = 211x - 5x² - 1,401 - 16x = -5x² + 211x - 16x - 1,401
R(x) = -5x² + 195x - 1,401
maximum revenue will be obtained for R'(x)
R'(x) = 2 · -5x + 195 = -10x + 195 = 0
195 = 10x
x = 19.5
the production level that yields a maximum profit should be 19.5
maximum monthly revenue
R(x) = -5·19.5² + 195·19.5 - 1,401 = -1,901.25 + 3,802.50 - 1,401 = $500.25

What is the value of k assuming the following equation has multiple solutions, 2x+6=6-3x+kx?
Answer:
k=5
Step-by-step explanation:
2x+6=6-3x+kx
Simplify
2x+6 = x(k-3) +6
If there are multiply solutions, both sides need to be equal
2 = k-3
Add 3 to each side
2+3 = k-3+3
5 =k
k=5
Answer:
k=5?
Step-by-step explanation:
you get, 5x +6 = 6 + kx
then take away six from both sides 5x= kx
then make it equal to zero 5x - kx =0
take out common factor of x , x (5-k) = 0
so k = 5

A while ago, Nicole bought shares of stock in a high-tech firm. At that time, the selling price was $60 per share. According to today's newspaper, a share is currently worth 30% more. What is the current value of one share?
Answer:
Step-by-step explanation:
1. Dividends
2. Capital gains
-The discounted present value of the sum of next period's dividend plus next period's stock price
-The discounted present value of all future dividends
P0 = [(Div1)/(1+R)] + [P1/(1+R)]
where Div 1 = expected dividend paid at year's end
P1 = expected price at year's end
R = discount rate
Answer:
$78
Step-by-step explanation:
A share is worth 30% more, so multiply 30% by 60 to get 30% of 60, which is 18. Then, add 18 to 60 because the share is 30% more, and you get 78.
if there is a ratio of 1:8 powder to water and there is 32 cups of powder how many cups of water is there
Answer:
256 cups of water
Step-by-step explanation:
the ratio is 1:8 powder to water
1 is multiplied by 32 to get 32 cups of water
so 8 x 32 = 256 cups of water
Answer: 2 cups of water

During the regular season, a National Basketball Association team plays 82 games and a National Football League team plays 16 games. In simplest form, what is the ratio of NFL regular season games to NBA regular season games?
Answer:
NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season

Aggregates for the construction of a reinforced concrete building are supplied by two companies, Company A and Company B. Orders are for Company A to deliver 700 truck loads a day and 300 truck loads a day from Company B. From prior experience it is expected that 5% of the material from Company A will be substandard and 3% of the material from Company B will be substandard. Part 1 What is the probability of substandard aggregates
Answer:
The probability of substandard aggregates is 0.044.
Step-by-step explanation:
We are given that orders are for Company A to deliver 700 truckloads a day and 300 truckloads a day from Company B.
From prior experience, it is expected that 5% of the material from Company A will be substandard and 3% of the material from Company B will be substandard.
Let the probability that orders are for Company A to deliver = P(A) = [tex]\frac{700}{1000}[/tex]
The probability that orders are for Company B to deliver = P(B) = [tex]\frac{300}{1000}[/tex]
Let event S = material which is substandard
So, the probability that the material from Company A will be substandard = P(S/A) = 0.05
the probability that the material from Company B will be substandard = P(S/B) = 0.03
Now, the probability of substandard aggregates is given by = P(S)
P(S) = P(A) [tex]\times[/tex] P(S/A) + P(B) [tex]\times[/tex] P(S/B)
= 0.7 [tex]\times[/tex] 0.05 + 0.3 [tex]\times[/tex] 0.03
= 0.044
Hence, the probability of substandard aggregates is 0.044.

The mean score on a set of 23 tests is 78. Suppose two more students take the test and score 70 and 56. What is the new mean?
(Round to the nearest tenth.)
Answer:
76.8
Step-by-step explanation:
total score of 23 tests=23×78=1794
now total of 25 tests=1794+70+56=1920
new mean=1920/25=76.80=76.8
Find the value that completes the ordered pair to describe the transformation of f(x) to g (x).
If (x, y) is a point on f(x), then
(x +
3
, y +
1
) is a point on g(x).
Answer:
we know that if: (x, y) is a point of f(x):
This means that f(x) = y.
Then (x + 3, y + 1) is a point of g(x)
This means that:
g(x + 3) = y + 1
Then we have two shifts.
For a real and positive number A.
A horizontal shift of A units to the right can be written as:
f(x - A)
A vertical shift of A units up can be written as:
f(x) + A.
Then in this case we have:
An horiozontal shift of 3 units to the right, and a vertical shift of 1 unit up, this means that:
g(x') = f(x' - 3) + 1.
then evaluating this at x' = x + 3
g(x + 3) = f(x + 3 - 3) + 1 = f(x) + 1 = y + 1
That is what we had initially.
Answer:
(x + 2, y + -2) is a point on g(x).

A study by a reputable research organization found that when presented with prints from the same individual, a fingerprint expert will correctly identify the match % of the time. In contrast, a novice will correctly identify the match % of the time. Consider a sample of different pairs of fingerprints, where each pair is a match. Complete parts a and b below. a. What is the probability that an expert will correctly identify the match in all pairs of fingerprints? The probability is nothing. (Round to four decimal places as needed.)
Answer:
0.5578
Step-by-step explanation:
Fingerprint correctly match 92 % of the time.
A novice that will correctly identify a match 75% the time.
Each of the attempts of matching a fingerprint with the individual is independent.
The number of pairs are 7.
a). So the probability that the expert will identify every pair correctly is
= 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92= 0.927 = 0.5578

g farmer brown wants to upgrade the fencing around his rectangular pasture.he would like to put a stone fence along one (1) side and a wooden fence along the other three (3) sides. the cost of the stone fence is $100 per linear foot, and the cost of the wooden fence is $20 per linear foot. a. if the pasture must have an area of 7,500 square feet, what are the dimensions of the field which will minimize the cost of the fencing
Answer:
The answer is below
Step-by-step explanation:
Let x represent the length of the fence along the stone side and y represent the length of the fence along the wood side. The cost of building the fence C(x) is given by:
C(x) = 100x + 20(2y + x)
C(x) = 100x + 40y + 20x
C(x) = 120x + 40y
Since the area = 7500 ft²,
⇒ xy = 7500
y = 7500/x
[tex]C(x) = 120x + 40(\frac{7500}{x} )\\\\C(x) = 120x+\frac{300000}{x}\\ \\Differentiating\ with\ respect\ to\ x:\\\\C'(x) =120-\frac{300000}{x^2} \\\\At\ minimum\ cost,C(x)=0\\\\hence:\\\\0=120-\frac{300000}{x^2}\\\\\frac{300000}{x^2}=120\\\\120x^2=300000\\\\x^2=\frac{300000}{120}\\ \\x^2=2500\\\\x=\sqrt{2500} \\\\x=50\ ft[/tex]
[tex]C"(x)=\frac{600000}{x^3}\\ \\C"(50)=\frac{600000}{50^3}=4.8>0\\\\y=\frac{7500}{x} =\frac{7500}{50} =150\ ft[/tex]
Hence to minimize cost, 50 ft of fence is used along the stone side and 150 ft of fence along the wood side
