Step-by-step explanation:
To find the answer, we need to use the distance formula.
[tex]d=\sqrt{(x-x)^2 +(y-y)^2}[/tex]
Let us look at our points. We have:
[tex](-2, 5)[/tex] and [tex](-6, -5)[/tex]
Now, let's identify our x's and y's:
x₁ = -2
y₁ = 5
x₂ = -6
y₂ = -5
Plug it in to the distance formula and simplify:
[tex]d=\sqrt{(-6+2)^2+(-5-5)^2}[/tex]
[tex]d=\sqrt{(-4)^2+(-10)^2}\\d=\sqrt{16 +100} \\d=\sqrt{116}\\[/tex]

Two computers working together can finish a search in 40 seconds. One of these computers can finish in 60 seconds. How long would it take the second computer to finish the same search?
Let the time taken by 2nd computer be = x
Time taken by first computer = 60 seconds
Total time taken by both = 40 seconds
So, equation becomes:
[tex]\frac{1}{60}+\frac{1}{x}=\frac{1}{40}[/tex]
[tex]\frac{-1}{x}=\frac{1}{60}-\frac{1}{40}[/tex]
Solving this we get,
x=120 seconds
Hence, the 2nd computer will take 120 seconds to finish a search alone.
It would take the second computer 120 seconds to finish the same search
Equation
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the rate of the first computer and y represent the rate of the second computer.
Two computers working together can finish a search in 40 seconds. Hence:
(1/x + 1/y)40 = 1It takes one of the computer 60 seconds, hence:
(1/x + 1/60)40 = 140/x + 2/3 = 1
x = 120 seconds
Therefore it would take the second computer 120 seconds to finish the same search

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 15. Find the probability that a randomly selected adult has an IQ less than 130.
Answer:
The probability would be 97.8%
Step-by-step explanation:
In order to find that, lets look at the amount of standard deviations away the amount given is. Since the number is 30 away from the mean, and the standard deviation is 15, we can find the total number of deviations it is away.
30/15 = 2
Now that we have that, we can look at the probability curve for standard deviations. Outside of 2 standard deviations above is only a 2.2% likelihood. Since that is the case, we can find the amount that would be under that as 100% minus the amount we just found.
100% - 2.2% = 97.8%

Answer:
5.545
Step-by-step explanation:
This problem can be easily solved by using the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles.
in this case, the formula can be applied in the following way
a^2 = b^2 + c^2 - 2*b*c*cos(α)
Where
a,b,c are each of the sides of the triangle,
α is the angle between sides b and c
(See attached picture)
If we use the formula we get
a^2 = (9)^2 + (6)^2 - 2*(9)(6)*cos(37°)
a^2 = 81 + 36 - 86.2526
a^2 = 30.747
a = sqrt(30.747)
a = 5.545

What is the value of x? If sin (8x - 18)º = cos (5x + 4)°
Answer:
Answer x = 8
Step-by-step explanation:
(5x + 4) + (8x - 18)= 90 The two angles must be complementary for this to work. Remove the brackets
5x + 4 + 8x - 18 = 90 Collect like terms
13x - 14 = 90 Add 14 to both sides
13x = 104 Divide by 13
x = 8 Answer
Check
Sin(8*8 - 18) = sin(64 - 18) = sin(46) = 0.7193
Cos(5*8 + 4) = cos(44) = 0.7193

Andrea is designing the seating arrangement for a concert in her local park.
The 1st row can only have 10 seats, and each row must have 4 more seats than the row in front of it.
How many seats will be in the 10th row of seats?
Answer:
There are 46 seats in row 10
Step-by-step explanation:
In order to find that we need to write this as an equation. We know that 6 is the constant and 4 is the coefficient for the variable. This would give us the equation:
y = 4x + 6
And this satisfies the equation for row 1, since when we put in the row number for x, it gives us the correct number of seats.
y = 4x + 6
y = 4(1) + 6
y = 4 + 6
y = 10
Now we can use that equation for any row. Let's use it for row 10
y = 4x + 6
y = 4(10) + 6
y = 40 + 6
y = 46

A. 130 degrees
B. 60 degrees
C. 65 degrees
D. 50 degrees
I really need an explanation along with the answer, thank you!!
Answer:
We know that [tex]\triangle ACE[/tex] is isosceles, that means [tex]\angle A \cong \angle E[/tex], by definition.
Also, [tex]\angle BDC \cong \angle DBC[/tex], because [tex]BD \parallel AE[/tex].
Then, we have [tex]115\° + \angle BDC = 180\°[/tex], by sumpplementary angles.
[tex]\angle BDC = 180 -115 = 65\° = \angle DBC[/tex]
Which means,
[tex]\angle C= 180 - 65 - 65[/tex], by definition.
[tex]\angle C= 50[/tex]
Then,
[tex]\angle A + \angle E + 50 = 180\\2\angle A = 180 - 50\\\angle A= \frac{130}{2}=65 = \angle E[/tex]
Therefore, the measures of vertex angles are 65 for the base angles of triangle and 50 for the different angle.
For the geometric series given by 1+2+4+ which of the following statements is FALSE?
S600>a600
S600>S599
S1=a1
None of the other 3 statements here are false
The false statement among the options given is 'None of the other 3 statements here are false', because all the other three statements about the geometric series are actually true.
Explanation:The question presents a geometric series: 1, 2, 4, ... Each term is double the previous term, which means that for this series, the common ratio (r) is 2. Now let us analyze the statements given:
S600 > a600: The sum of the first 600 terms of the series will be greater than the 600th term.
This is true, since the sum of a geometric series to n terms is given by the formula Sn = a1(1 - rn)/(1 - r) for r > 1, where Sn is the sum of the first n terms, a1 is the first term, and r is the common ratio.
Since the sum involves multiple terms and all terms are positive, it will be bigger than the last term.
S600 > S599: The sum of the first 600 terms will be greater than the sum of the first 599 terms.
This is also true, since each term added to the series is positive, so the sum will increase.
S1 = a1: The sum of the first term equals the first term itself.
This is true because the first term of the series is 1, and the sum of just one term (i.e., the first term) is the term itself.
Therefore, the false statement is 'None of the other 3 statements here are false' because actually, none of the other three statements provided are false.
Final answer:
The presented geometric series has a common ratio greater than 1, so the sum of the first 600 terms is greater than the 600th term; similarly, the sum of 600 terms is greater than the sum of 599 terms. Since all provided statements are true, the answer is that 'None of the other 3 statements here are false'.
Explanation:
The question presents a geometric series with the first term 1 and a common ratio of 2. This series is 1+2+4+8+... and so on. We are asked to identify which of the given statements is false regarding the series.
S600 > a600: This statement says that the sum of the first 600 terms is greater than the 600th term. In a geometric series where the common ratio is greater than 1, the sum of the first n terms is indeed greater than the nth term, so this statement is true.S600 > S599: This statement indicates that the sum of the first 600 terms is greater than the sum of the first 599 terms. Since each term in the series is positive, adding another term will always increase the sum, thus this statement is also true.
S1 = a1: This statement equates the sum of the first term to the first term itself. Since there's only one term involved, they are the same. Therefore, this statement is true.
By process of elimination, since the other statements are true, the correct answer would be 'None of the other 3 statements here are false'.
Jeremy and Robin like to collect nickels. Jeremy has n nickels, and Robin has 55 nickels. Together they have a total of 100 nickels.
Answer:
Jeremy has 45 nickels.
Step-by-step explanation:
I'm guessing the question is how many nickels does Jeremy have.
n + 55 = 100
n = 45
Answer:
45 nickels.
Step-by-step explanation:
We have been given that Jeremy and Robin like to collect nickels. Jeremy has n nickels, and Robin has 55 nickels. Together they have a total of 100 nickels.
We can represent our given information in an equation as:
[tex]n+55=100[/tex]
[tex]n+55-55=100-55[/tex]
[tex]n=45[/tex]
Therefore, Jeremy has 45 nickels.
A rectangle has a length that is 2 meters more than the width. The area of the rectangle is 288 square meters. Find the dimensions of the rectangle.
Answer:
L = 18 and w = 16
Step-by-step explanation:
The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.
[tex]A = l*w\\288 = w(2+w)\\288 = w^2 + 2w[/tex]
To solve for w, move 288 to the other side by subtraction. Then factor and solve.
[tex]w^2 + 2w - 288 = 0 \\(w +18)(w-16) = 0\\[/tex]
Set each factor equal to 0 and solve.
w - 16 = 0 so w = 16
w + 18 = 0 so w = -18
Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.
This means the length is 16 + 2 = 18.

* 2) y = -tan(x - π/2) ⇒ (A)
∵ y = -cot(x - π/2)
# (x - π/2) means the graph translated horizontally to
the right π/2 units
# -cot(x - π/2) means the graph reflected across the x-axis
∴ The graph is (C)
* 3) y = -cot(x - π/2) ⇒ (C)

In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalization. The etch rate is an important characteristic in this process and known to follow a normal distribution. Two different etching solutions have been compared, using two random samples of 10 wafers for each solution. Assume the variances are equal. The etch rates are as follows (in mils per minute): Solution 1 Solution 2 9.7 10.6 10.5 10.3 9.4 10.3 10.6 10.2 9.3 10.0 10.7 10.7 9.6 10.3 10.4 10.4 10.2 10.1 10.5 10.3 Calculate sample means of solution 1 and solution 2
Answer:
Sample mean for solution 1: 19.27; sample mean for solution 2: 10.32
Step-by-step explanation:
To find the sample mean, find the sum of the data values and divide by the sample size.
For solution 1, the sum is given by:
9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7
The sample size is 10; this gives us
192.7/10 = 19.27
For solution 2, the sum is given by:
10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2
The sample size is 10, this gives us
103.2/10 = 10.32
The sample mean for Solution 1 is 10.05 mils per minute, while the sample mean for Solution 2 is 10.32 mils per minute. These figures represent the average etch rates of each solution in the semiconductor manufacturing process. So here the sample mean should be calculated.
Explanation:To calculate the sample means of Solution 1 and Solution 2, we first sum up the etch rates of each solution, and then divide by the number of samples in each solution.
For Solution 1, the etch rates sum up to 100.5 mils per minute. Dividing this by 10 (number of samples), we get a sample mean of 10.05 mils per minute.
For Solution 2, the etch rates sum up to 103.2 mils per minute. Dividing this by 10 (number of samples), we get a sample mean of 10.32 mils per minute.
So, the sample means for Solution 1 and Solution 2 are 10.05 and 10.32 mils per minute respectively. These means are useful to compare the average efficiency of these two solutions as a part of normal distribution analysis in the semiconductor manufacturing process.

In circle F, what is the measure of EFD?
A. 17.5°
B. 35°
C. 60°
D. 70°
Answer: Option D.
Step-by-step explanation:
To solve this exercise you must keep on mind the Angle at the Center Theorem.
According to the Angle at the Center Theorem, an inscribed angle is half of the central angle.
Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:
[tex]BAC=\frac{EFD}{2}[/tex]
- Solve for EFD.
[tex]EFD=2*BAC[/tex]
- When you substitute values. you obtain:
[tex]EFD=2(35\°)\\EFD=70\°[/tex]
Answer:
Option B. ∠EFD = 35°
Step-by-step explanation:
In a circle F, it has been given mED = mDB = mBC
We have to find the measure of ∠EFD
We should always remember the inscribed angle theorem which states that the measure of an inscribed angle is always half the measure of intercepted arc.
m(arc BC) = 2×∠CAB = 2×35 = 70°
Now it has been given in the question
mED = mBC
Therefore m(arc ED) = 70°
Again applying the same theorem
m(arc ED) = 2×∠EFD
70° = 2×∠EFD
m∠EFD = [tex]\frac{70}{2}=35[/tex]
Option B. 35° is the answer.

Change from General Conic Form to Standard Form: 137+64y=-y^2-x^2-24x
Answer:
(x + 12)² + (y + 32)² = 1031
Step-by-step explanation:
137 + 64y = -y² - x² - 24x
Arrange the terms in descending powers of x and y.
x² + 24x + y² + 64y = -137
Complete the squares for x and y
(x² + 24x + 144) + (y² + 64y + 1024) = -137 + 144 + 1024
Write the equation as the squares of binomials of x and y
(x + 12)² + (y + 32)² = 1031
This is the equation of a circle with centre at (-12, -32) and radius r = √1031.
