Find mJTS

A) 104°
C) 120°
E) 87°
B) 128°
D) 74°

Answers

Answer:

104

Step-by-step explanation:

∠JTS = ∠SRT  + ∠TSR   {exterior angles equals sum of opposite interiror angles}

27x - 4 = 18x + 2 + 30

27x  - 4 = 18x + 32

Add 4 to both sides

27x = 18x + 32 + 4

27x = 18x + 36

Subtract  18x from both sides

27x - 18x = 36

9x = 36

Divide  both sides by 9

x = 36/9

x = 4

∠JTS = 27x - 4

         = 27*4 - 4

         = 108 - 4

        = 104

Shelby invests £14000 in a savings account. The account pays 2.5% compound interest per year.
Work out the value of her investment after 2 years.​

Answers

Answer:

70000

Step-by-step explanation:

Answer:

£14708.75

Step-by-step explanation:

Always start with the original amount, in this case 14000.

Then, because it's an increase, add 2.5 to 100. You could also think of it as adding 2.5% to 100%, which is 102.5%. We then divide that by 100.

So far our calculation is 14000 x 1.025.

We now need to do this for the two days on. We can do this in 2 ways.

1. 14000 x 1.025 x 1.025

or.

2. 14000 x 1.025^2

They're both the same thing.

We then type that calculation into your calculator and you should get £14708.75

Hope that helped :)

Given the function g ( x ) = x 2 + 10 x + 20 g(x)=x 2 +10x+20, determine the average rate of change of the function over the interval − 9 ≤ x ≤ − 3 −9≤x≤−3.

Answers

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

identify the slope and the y-intercept. Show your complete solution.
7x - 2y = 13​

Answers

Answer: The slope is 3.5 (or 7/2) and the y-intercept is -6.5 (or -13/2).

Solving Steps:
The equation must be put in slope-intercept form to easily identify the slope and y-intercept.
Slope-intercept form: y = mx + b

7x - 2y = 13
-2y = -7x + 13
y = 3.5x - 6.5
Improper fraction form: y = 7/2x - 13/2

Answer:

C. 15

Step-by-step explanation:

1. First, let's solve the system of equations; [tex]-m - n = 5, m - n = -3[/tex]

Solve -m - n = 5 for m.

[tex]-m -n = 5[/tex] [tex]-m-n+n=5+n[/tex] [tex]-m = n + 5[/tex] [tex]\frac{-m}{-1} = \frac{n+5}{-1}[/tex] [tex]m = -n - 5[/tex]

Substitute -n - 5 for m in m - n = -3.

[tex]m - n = -3[/tex] [tex]-n - 5 - n = -3[/tex] [tex]-2n-5=-3[/tex] [tex]-2n-5+5=-3+5[/tex] [tex]-2n = 2[/tex] [tex]\frac{-2n}{-2} = \frac{2}{-2}[/tex] [tex]n = -1[/tex]  

Substitute -1 for n in m = -n - 5.

[tex]m = -n - 5[/tex] [tex]m = -(-1) - 5[/tex] [tex]m = 1 - 5[/tex] [tex]m = -4[/tex]

2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.

[tex]m^2-n^2[/tex] [tex](-4)^2-(-1)^2[/tex] [tex]16 - (-1)^2[/tex] [tex]16 - 1[/tex] [tex]15[/tex]

Therefore, the answer is C. 15!

If JM=30 and LM=8, what is KM?

Answers

If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.

How to determine the length of side KM?

In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;

Side JL = [(30 + 8) × x]/2

Side JL = 38x/2

Side JL = 19x.

Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;

19x = √[(30² + x²)(x² + 8²)]/2

38x = √[(30² + x²)(x² + 8²)]

By taking the square of both sides, we have:

38²x² = (900 + x²)(x² + 64)

38²x² = 900x² + 57,600 + x⁴ + 64x²

38²x² = 964x² + 57,600 + x⁴

(x² - 240)² = 0

x² = 240

x = √240

x = 15.49 units.
