Answers
Answer:
Distance between B and C is 9.6 miles.
Step-by-step explanation:
By applying tangent rule in the given right triangle ABC,
tan(58°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{BC}{6}[/tex]
1.60 = [tex]\frac{BC}{6}[/tex]
BC = 9.6 mi
Therefore, Distance between B and C is 9.6 miles.

what is order of operations and why is it important
Answers
Answer:
PEMDAS
Step-by-step explanation:
The order of operations is the order in which you solve an equation to find the correct answer. This is very important because randomly solving parts of an equation without using the order of operations will result in the wrong answer. The order of operations is PEMDAS which stands for: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Example:
[tex](2*2)^{2}+6/3-1[/tex]
Using PEMDAS to solve this equation we get 17 as our answer. However, if we solve it in order of how it appears we end up with 19/3 or 6.33, which is a very different answer.

if dy/dx = 2 - y, and if y = 1 when x = 1, then y = ??? PHOTO ATTACHED
Answers
Answer:
y=2-e^(1-x)
Step-by-step explanation:
This can be solved by separating the variables.
dy/dx=2-y
Multiply both sides by dx
Divide 2-y on both sides
dy/(2-y)=dx
Integrate both sides
-ln|2-y|=x+c
Multiply both sides by -1
ln|2-y|=-x-c
Equivalent logarithm form
2-y=e^(-x-c)
Minus 2 on both sides
-y=e^(-x-c)-2
Multiply both sides by -1
y=-e^(-x-c)+2
The ordered pair (1,1) belongs to the curve so we have
(I'm going to use this earlier form -ln|2-y|=x+c)
-ln|2-1|=1+c
-ln|1|=1+c
-0=1+c
0=1+c
Minus 1 on both sides
-1=c
Answer:
y=-e^(-x-(-1))+2
Or
y=-e^(-x+1)+2
Or
y=2-e^(1-x)

Answers
Answer:
65 degrees
Step-by-step explanation:
1) Find the value of x
The sum of all the interior angles of a triangle is always 180 degrees. Knowing this, we can construct the following equation:
[tex](2x-5)+(115-x)+x=180[/tex]
Open up the parentheses
[tex]2x-5+115-x+x=180[/tex]
The two x's cancel out
[tex]2x-5+115=180\\2x+110=180[/tex]
Subtract 110 from both sides
[tex]2x+110-110=180-110\\2x=70[/tex]
Divide both sides by 2
[tex]2x/2=70/2\\x=35[/tex]
Therefore, x is equal to 35.
2) Find the value of <C
[tex]C=2x-5[/tex]
Plug 35 into the equation as x
[tex]C=2(35)-5\\C=70-5\\C=65[/tex]
Therefore, the value of angle C is 65 degrees.

In a random sample of 8 residents of the state of Montana, the mean waste recycled per person per day was 3.0 pounds with a standard deviation of 0.23 pounds. Determine the 99% confidence interval for the mean waste recycled per person per day for the population of Montana. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answers
Answer:
at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )
Step-by-step explanation:
Given the data in the question;
sample size n = 8
mean x' = 3.0
standard deviation σ = 0.23
To calculate the confidence interval, we use the following expression;
x' ± [tex]t_{\alpha /2, df[/tex]( σ/√n) ------- let this be equation
now, at 99% confidence interval;
∝ = 1 - 99% = 1 - 0.99 = 0.01
degree of freedom df = n - 1 = 8 - 1 = 7
hence t-critical value = 3.499
in equation 1, we substitute in our values;
⇒ 3.0 ± 3.499( 0.23/√8 )
⇒ 3.0 ± 0.2845
⇒ 3.0 - 0.2845, 3.0 + 0.2845
⇒ ( 2.7155, 3.2845 )
Therefore at 99%, Confidence interval is ( 2.716, 3.285 )
( 2.716 < μ < 3.285 )

As part of a study of corporate employees, the director of human resources for PNC, Inc. wants to compare the distance traveled to work by employees at its office in downtown Cincinnati with the distance for those in downtown Pittsburgh. A sample of 40 Pittsburgh employees showed they travel a mean of 370 miles per month. A sample of 35 Cincinnati employees showed they travel a mean of 380 miles per month. Do the Cincinnati employees travel the same distance to work, on average, as the Pittsburgh employees
Answers
Answer:
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
Step-by-step explanation:
40 Pittsburgh employees mean travel time = 370 miles
35 Cincinnati employees mean travel time = 380 miles
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
mean = total distance / Number of employees
For Pittsburgh
370 = x / 40
x = 370 * 40 = 14,800 miles
For Cincinnati
380 = y / 35
y = 380 * 35 = 13,300 miles

Answer:
x = 28.5
Step-by-step explanation:
1. Write the equation
4(x+9) = 3(2x - 7)
2. Distribute
4x + 36 = 6x - 21
3. -4x from both sides
36 = 2x - 21
4. +21 on both sides
57 = 2x
5. Divide 2 on both sides
x = 28.5

Write a list of steps that are needed to find the measure of ∠B.
Answers
Step-by-step explanation:
Angle BCA + Angle BCD = 180 (Sum of angles on a straight line)
Angle BCA + 113 = 180
Angle BCA = 180 - 113
= 67
Angle BCA + Angle A + Angle B = 180 (Sum of angles in a triangle)
67 + 72 + Angle B = 180
139 + Angle B = 180
Angle B = 180 - 139
= 41
The measure of ∠B is m∠B = 41°.
What is a Triangle?A polygon which has three sides and three vertices is called as triangle.
The sum of all the angles of the triangle is 180°.
Given:
The sum of the exterior angle and adjacent angle with is 180°.
So, ∠BCD = 180 - 113 = 67°.
The sum of all the angles of the triangle is 180°.
So,
72° + 67° + ∠B = 180°.
∠B = 180° - 139°.
∠B = 41°.
Therefore, ∠B = 41°.

[tex]y-y_{1}=m(x-x_{1})[/tex]
Where:
y(1) is the y value of the first pointx(1) is the x value of the first pointm is the slopeThe first point is (3,-4) and the second point is (3,8)
Let's first find the slope. The equation of m is given by:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{8-(-4)}{3-3}[/tex]
Here the slope is not defined, so we can not find the equation of this line, because it is not a function.
