Step-by-step explanation:
Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.
If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.

x−2y=10 ; 6x+3y=15
Step: Solve x −2y= 10for x:
x − 2y + 2y = 10 + 2y (Add 2y to both sides)
x=2y+10
Step: Substitute 2y+10 forx in 6x+3y=15:
6x+3y=15
6x+3y=156(2y+10)+3y=15
15y+60=15 (Simplify both sides of the equation)
15y+60+−60=15+−60 (Add -60 to both sides)
15y=−45
15y/15=−45/15(Divide both sides by 15)
y=−3
Step: Substitute −3 for y inx=2y+10:
x=2y+10
x=(2)(−3)+10
x=4(Simplify both sides of the equation)

In a right triangle ΔABC, the length of leg AC = 5 ft and the hypotenuse AB = 13 ft. Find:
The length of the angle bisector of angle A
Answers
Answer:
∠A is (5/3)√13
Step-by-step explanation:
The cosine of ∠A is [tex]\frac{AC}{AB}[/tex] = [tex]\frac{5}{13}[/tex]
The cosine of half of ∠A is given by the half-angle formula:
cos(A/2) = √((1 +cos(A))/2) = √((1 + 5/13)/2) = √(9/13) = 3/√13
The length of the segment b is found from ...
cos(A/2) = 5/b [adjacent side/hypotenuse]
∠ A = 5/cos(A/2) = 5/(3/√13)
∠ A = (5/3)√13
If Needed in decimal form : 6.01

A The mean would increase.
B The median would decrease.
C The interquartile range would increase.
D The median of the lower quartile would stay the same.
Answers
Answer:
A The mean would increase.
Step-by-step explanation:
mean = sum of numbers ÷ how many numbers there are
the mean with the outlier 11:
(11 + 85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 9 = 81.4
the mean when removing the outlier 11:
(85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 8 = 90.25
the mean has now increased

Tell whether the angels are adjacent or vertical. Then find the value of x.
(please show how you solved the problem!)
Answers
Answer:
Angles: adjacent
x = 18
Step-by-step explanation:
Adjacent Angles: angles that border each other to the left/right
Vertical Angles: opposite set of angles that are congruent
Given these definitions, these angles are not only adjacent, but also right angles. Right angles add to 90°.
Thus, 3x + 2x = 90Step 1: Combine like terms.
[tex]3x + 2x = 90[/tex] [tex]5x = 90[/tex]Step 2: Divide both sides by 5.
5x ÷ 5 = 90 ÷ 5x = 18Therefore, the answer is adjacent and x = 18.
At what point on the curve y = 9 + 2ex − 5x is the tangent line parallel to the line 5x − y = 8?
(x, y) = ?
Answers
Answer:
[tex](\ln(5), 19-5\ln(5))[/tex]
Step-by-step explanation:
The line can be represented as y=5x-8, so the slope of the line is 5.
The derivative of the curve is:
[tex]\frac{d}{dx} [9+2e^x-5x]\\=\frac{d}{dx} [9]+\frac{d}{dx} [2e^x]-\frac{d}{dx} [5x]\\=2e^x-5\\[/tex]
We need to set that equal to 5 to find the x coordinate of our desired point
[tex]2e^x-5=5\\2e^x=10\\e^x=5\\x=\ln(5)[/tex]
Now, just plug in x in the curve to solve for y:
[tex]9+2e^{\ln(5) } -5\ln(5) = y\\9+10-5\ln(5)=y\\19-5\ln(5)=y[/tex]
Line 5x y = 8 has a slope of 5. This means that the tangent line that runs parallel to this line must also have a slope of 5.
To solve this equation
dy/dx = 2ex 5 is the derivative of the function y = 9 + 2ex 5x. Consequently, 2ex 5 is equal to the slope of the tangent line at any location.
When we set the slope of the tangent line to 5, we obtain:
2ex − 5 = 5
2ex = 10
e^x = 5
Taking the natural logarithm of both sides, we get:
ln(e^x) = ln(5)
x = ln(5)
Therefore, ln(5) is the x-coordinate of the crossing point.
We can enter this value of x into the original function to determine the y-coordinate:
y = 9 + 2e^(ln(5)) − 5(ln(5))
y = 9 + 10 − 5ln(5)
y = 15 − 5ln(5)
As a result, the intersection is at (ln(5), 15 5ln(5)).
To sum up, (ln(5), 15 5ln(5)) is the point on the curve y = 9 + 2ex 5x where the tangent line is parallel to the line 5x y = 8.
