I'm not sure about the first one on question 5 though.
The endpoints of AC are A(-8, 9) and C (1, -3). Point B(-2, 1) lies on AC. What
is the ratio AB: BC?
A 1:2
B
1:1
C) 2:1
D) 3:1
Answer:
c)2:1..................
Answer:
C
Step-by-step explanation:
Find the distance of AB:
Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]
[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]
Find the distance of BC:
Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]
[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]
AB=10 units
BC=5 units
AB:BC = 10:5=2:1

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

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!

Miguel runs 5 miles in 38 minutes. At the same rate, how many miles would he run in 57 minutes?
7,5 miles
Step-by-step explanation:
5/x = 38/57
38x = 5 × 57
38x = 285
x = 285/38
x = 7,5 miles
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.
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).

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.
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

Find mJTS
A) 104°
C) 120°
E) 87°
B) 128°
D) 74°
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
