Answer:
9. m(YZ) = 102°
10. m(JKL) = 192°
11. m<GHF = 75°
Step-by-step explanation:
9. First, find the value of x
4x + 3 = 3x + 15 (inscribed angle that are subtended by the same arc are equal based on the inscribed angle theorem)
Collect like terms
4x - 3x = -3 + 15
x = 12
4x + 3 = ½(m(YZ)) (inscribed angle of a circle = ½ the measure of the intercepted arc)
Plug in the value of x
4(12) + 3 = ½(m(YZ))
48 + 3 = ½(m(YZ))
51 = ½(m(YZ))
Multiply both sides by 2
51*2 = m(YZ)
102 = m(YZ)
m(YZ) = 102°
10. First, find the value of x.
7x + 5 + 6x + 6 = 180° (opposite angles in an inscribed quadrilateral are supplementary)
Add like terms
13x + 11 = 180
13x = 180 - 11
13x = 169
x = 169/13
x = 13
7x + 5 = ½(m(JKL)) (inscribed angle of a circle = ½ the measure of the intercepted arc)
Plug in the value of x
7(13) + 5 = ½(m(JKL))
96 = ½(m(JKL))
Multiply both sides by 2
2*96 = m(JKL)
m(JKL) = 192°
11. First, find x.
5x + 15 = ½(11x + 18) (inscribed angle of a circle = ½ the measure of the intercepted arc)
Multiply both sides by 2
2(5x + 15) = 11x + 18
10x + 30 = 11x + 18
Collect like terms
10x - 11x = -30 + 18
-x = -12
Divide both sides by -1
x = 12
m<GHF = 5x + 15
Plug in the value of x
m<GHF = 5(12) + 15
m<GHF = 60 + 15
m<GHF = 75°

A hot air balloon descended 3240 feet in an hour. Find the change in altitude per minute?
Unit analysis is a tool that we can use to convert units. It involves multiplying the original number by a fraction to cancel out units.
Solving the QuestionWe're given:
\(\dfrac{3240\hspace{4}feet}{hour}\)
We also know that:
\(\dfrac{hour}{60\hspace{4}minutes}\)
Multiply the two to cancel out the hour:
\(\dfrac{3240\hspace{4}feet}{hour}\times\dfrac{hour}{60\hspace{4}minutes}\\\\=\dfrac{3240\hspace{4}feet}{60 minutes}\)
Simplify:
\(=\dfrac{54\hspace{4}feet}{minute}\)
Answer\(\dfrac{54\hspace{4}feet}{minute}\)

Does the series converge or diverge? If it converges, what is the sum? Show your work.
Step-by-step explanation:
This is a geometric series where our common ratio is -1/2, and a is -4
Since r is less than -1, this series converges so
The sun is
\( \frac{ - 4}{1 + 0.5} \)
\( \frac{ - 4}{1.5} = - \frac{8}{3} \)

7. Find the length of YU Round to the nearest hundredth.
8. Find STR.
Answer:
YU = 4.82. angle STR = 23°
Step-by-step explanation:
7) Angle between U and V = 72°, since angles on a straight line add up to 180°. so angle UV = 180 - 108 = 72°.
similarly, angle YU = 180 - 85 - 72 = 23°.
length of circumference of full circle = π X diameter = π (2r)
= 2πr (radius = half of diameter).
circumference = 2π(12) = 24π.
there are 360° in full circle.
remember that angle YU = 23°.
length YU = (23/360) X 24π
= (23π)/15
= 4.817
= 4.82 to nearest one hundredth.
8) triangle RST sits inside of half the circle, ie in the semicircle.
angle RST = 90° because the angle in a semicircle = 90°.
there are 180° in a full triangle.
since angle RST = 90°, angle STR must be less than 180 - 90.
angle STR < 90°. so STR must be 23°.

Find f '(x) of f(x) = 3/2x+4
Given:
\(f(x)=3\sqrt[]{2x+4}\)The objective is to find inverse of the function.
Consider the given function as,
\(y=3\sqrt[]{2x+4}\)The inverse of the function can be calculated by replacing the varibales x and y of the function.
Then, the function will be,
\(x=3\sqrt[]{2y+4}\)Now, solve for y.
\(\begin{gathered} \frac{x}{3}=\sqrt[]{2y+4} \\ 2y+4=(\frac{x}{3})^2 \\ 2y+4=\frac{x^2}{3^2}^{} \\ 2y=\frac{x^2}{9}^{}-4 \\ y=\frac{1}{2}(\frac{x^2}{9}^{}-4) \\ y=\frac{x^2}{18}^{}-\frac{4}{2} \\ y=\frac{x^2}{18}^{}-2 \end{gathered}\)Thus, the inverse function is,
\(f^{-1}(x)=\frac{x^2}{18}^{}-2\)Hence, the required inverse of the function is obtained.

The speed of a passenger train is 6 mph faster than the speed of a freight train. The passenger train travels 260 miles in the same time it takes the freight train to travel 230 miles. Find the speed of each train.
Step-by-step explanation:
let speed of freight train be x
speed of passenger train = x+6
Passenger train distance = 280 miles
freight train 250 milesthe times taken for these distances is the same
280/(x+6)=250/x
280x=250(x+6)
280x=250x+1500
30x = 1500
x= 50 mph the speed of freight train.
x+6= 50+6 = 56mph = speed of passenger train.

A discount of 10 percent was given. If a further discount of 10percent was given in the reduced price, calculate the total single discount given in the marked price .
Answer:
let marked price = x
on 10% discount, price= x-10%of x
=x-(10x/100)
=x-(x/10)
=9x/10
on further 10% discount, total discount = 10% of 9x/10
=10/100 * 9x/10
= 9x/100
= 9%of x

What is the range of the function
f(x) = 2x + 3
when the domain is (-3,-1,1}?
Answer:
The range is just the y-values that result from plugging in the given x-values.
Meaning, if x = -3, y = f(-3) = 2(-3)+3 = -3
So the first value in your range is -3.
Now plug in (-1)
y = f(-1) = 2(-1)+3 = 1
The next value in your range is 1
Plug in the 1.
y = f(1) = 2(1) + 3 = 5
The last value in your range is 5
So the range is {-3, -1, 5}
