What is Line segment?Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
Given that;
The coordinate are,
⇒ A = (- 5x, 4y)
⇒ B = (- 2x, - 4y)
Now,
Since, We know that;
The distance between the points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,
⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²
⇒ d = √(3x)² + (- 8y)²
Thus, The values needed to find the length AB is find as;
⇒ AB = √(3x)² + (- 8y)²

What is the number of degrees
Answers
Answer:
Step-by-step explanation:
Remark
Since this is a multiple choice question, you need not worry excessively about solving the equation that sin(4x) and Cos(3x + 13) produce. It can be done, but you will spend a lot time and drink a lot of coffee doing it.
C
The wording of this problem is not the best. 13 is not in any way considered.
4x = 4*13 = 523x + 13 = 52.Not only are the two angles equal (52) but they add to 104 which is greater than 90.
11 is the next one you should look at
4*11 = 44
3*11 + 13 = 46
That gives you the right answer, but the question you have to ask yourself is are you answering the question? I don't think you are. The question is the number of degrees in the smaller angle. I think that means that you have already substituted a value for x.
I think the answer is C.
A company is considering two different prize policies for a sweepstakes.

In Policy B, the cost to enter is $10, and the overall win rate is 15%, 80% of the winners receive a product worth $10, 18% of the winners receive a product worth $50, and 2% of the winners receive $250 in cash.

a. Policy A, by 1500
b. Policy A, by 4000
c. Policy B, by 1500
d. Policy B, by 4000

Answers
The policy that makes the largest proſit for the company is Policy A, by $1500.
Which policy makes the largest proſIt?Profit is the amount paid by people to enter the sweepstakes less the amount they can win.
Policy A's profit: $5 - 0.1[(0.9 x $10) + (0.095 x $50) + (0.005 x $250)] = $5 - 1.5 = $3.5
$3.5 X 10,000 = $35,000
Policy B's profit:10 - 0.15[(0.8 x 10) + (0.18 x 50) + (0.02 x 250) = 10 - 3.30 = 6.7$6.7 X 5000 = $33500

Determine the zeros, sign and extreme values of the function y = -x³ + 8x²-16x.
Answers
Step-by-step explanation:
To find extreme values, take the first derivative
[tex]y = - 3 {x}^{2} + 16x - 16[/tex]
Solve the equation for x.
[tex]x = \frac{ - 16 + \sqrt{256 - 192} }{ - 6} [/tex]
or
[tex]x = \frac{ - 16 - \sqrt{256 - 192} }{ - 6} [/tex]
[tex]x = \frac{ - 16 + \sqrt{64} }{ - 6} [/tex]
or
[tex]x = \frac{ - 16 - \sqrt{64} }{ - 6} [/tex]
We then get
[tex]x = \frac{4}{3} [/tex]
or
[tex]x = 4[/tex]
So our extreme values occur at x=4/3 and x=4
Zeroes:
[tex] - {x}^{3} + 8 {x}^{2} - 16x[/tex]
[tex] - x( {x}^{2} - 8x + 16)[/tex]
[tex] - x(x - 4) {}^{2} [/tex]
[tex] - x = 0[/tex]
[tex](x - 4) {}^{2} = 0[/tex]
[tex]x = 4[/tex]
So we have a double root at 4, and a root of 0. We have two positive roots and one non negative root
End behavior:
Since we have a negative leading coefficient and a odd degree, as x becomes more positive, y will become negative and as x becomes more negative, y will become positive.

Answers

Fraction Form: x = 7/5
Decimal Form: x = 1.4
Mixed Number Form: x = 1 1/2
Step-by-step explanation:
Step-by-Step Explanation:
2(1 - 5x) + 4 = -8
2 * 1 - 2 * 5x + 4 = -8
2 - 10x + 4 = -8
2 - 10x = -8 - 4
-10x = -8 - 4 - 2
-10x = -14
10x = 14
x = 14/10
=> x = 7/5
Therefore, x = 7/5
This question is designed to be answered with a calculator. which inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve f(x) = 2 cos(2x) over the interval [0, pi/ 4] using 3 equal subdivisions?
a.) l < t < r
b.) r < l < t
c.) r < t < l
d.) t < r < l
Answers
The inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is C. r < t < l.
How to illustrate the inequality?From the information given, it should be noted that f'(x) is negative. Therefore, L > R. Also since f"(x) is negative, T > R.
f(x) = 2 cos 2x.
f'(x) = -4 sin 2x
f"(x) = -8 cos 2x
Therefore, the inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is r < t < l

a term salinity refers to the amount of salt in water. the salinity of earths oceans is about 525 grams of dissolved salt for evert 15 kilograms of water. find the grams of salt for every gram of ocean water
Answers
Answer:
0.035 grams
Step-by-step explanation:
Grams of salt per gram of ocean water
Divide the amount of salt by amount of water525 g / 15 kg525 g / 15000 g [∴1 kg = 1000 g]0.035 / 1For every gram of ocean water, there is 0.035 grams of salt dissolved in it.
The salinity of earths oceans,
→ a = 525 g
Amount of water for the salinity,
→ b = 15 kg
→ b = 15 × 1000
→ [ b = 15000 g ]
Then find the grams of salt for every gram of ocean water,
→ a ÷ b
→ 525 ÷ 15000
→ 0.035 g
Hence, answer is 0.035 grams of salt.
A pie shop sells 32 apple pies, 33 pumpkin pie,20 cherry pies, and 15 chocolate pies.What percentage of pies were sold were apples or cherry
Answers
The percentage of pies sold that were apples or cherry is 52%
How to determine the percentage of apples or cherry?The given parameters are:
Apple = 32Pumpkin = 33Cherry = 20Chocolate = 15The total number of pies is:
Total = 32 + 33 + 20 + 15

Total = 100
The percentage of apples or cherry is calculated as:
Percentage = (Apple + Cherry)/Total
So, we have:
Percentage = (32 + 20)/100
Evaluate the quotient
Percentage = 0.52
