Answer:
(x - 43)(x + 43)
Step-by-step explanation:
x² - 43² ← is a difference of squares and factorises in general as
a² - b² = (a - b)(a + b), then
x² - 43²
= (x - 43)(x + 43)
Answer:
(x - 43)(x + 43).
Step-by-step explanation:
This is the difference of 2 squares:
a^2 - b^2 = (a - b)(a + b) so here we have:
x^2 - 43^2 = (x - 43)(x + 43).
I do not get this question: 6b-5b+(-8b)=?
Answer:
-7b
Step-by-step explanation:
Ok soo you have add the terms.
1b+(-8b)=-7b
Have a good!!
Answer:
-9b
Step-by-step explanation:
i'm assuming this is just combining like terms so if you ignore the (b) you will have
6-5+(-8)
-1+(-8)
-9
then you put back the variable and you get -9b
2. Create a problem and draw a strip diagram to go with
the following equation: 85 - (2 x 18) = 49
What is an equation of the line that passes through the points (4,-1) and (8,5)?
Answer:
y=3/2x-7
Step-by-step explanation:
the equation of the line for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept.
we are given two points: (4,-1) and (8,5)
the equation for slope is (y2-y1)/(x2-x1)
label the points:
x1=4
y1=-1
x2=8
y2=5
now substitute into the equation:
m=(5--1)/(8-4)
m=6/4
m=3/2
the slope of the line is 3/2
here is our equation so far:
y=3/2x+b
we need to find b
since the equation will pass through the points, we can substitute either one into the equation to find b
let's use (4,-1) as an example
substitute into the equation
-1=3/2(4)+b
-1=6+b
-7=b
the y intercept is -7
so the equation is y=3/2x-7
hope this helps!

What is Kimberly's error?
A Kimberly did not find the inverse cosine of the value she calculated.
OB. Kimberly did not find the inverse sine of the value she calculated.
OC. Kimberly found the measure of angle N, not M.
D. Kimberly made a computational error.
E Kimberly did not apply the Law of Sines correctly
А
Answer:
The error is;
B. Kimberly did not find the inverse sine of the value she calculated
Step-by-step explanation:
The given parameters of the triangle ΔLMN are;
[tex]\overline {LN}[/tex] = 16
[tex]\overline {NM}[/tex] = 10
∠L = 33°
By sine rule, we have;
[tex]\dfrac{sin \ M}{16} = \dfrac{sin \ L}{10} = \dfrac{sin \ N}{\overline {LM}}[/tex]
Given that ∠L = 33°, we have;
[tex]\dfrac{sin \ M}{16} = \dfrac{sin \ 33^{\circ}}{10}[/tex]
Therefore, we have;
[tex]sin \ M = 16 \times \dfrac{sin \ 33^{\circ}}{10} \approx 0.8714[/tex]
sin M ≈ 0.8714
[tex]\therefore m \angle M = sin^{-1} \, (sin \ M)\approx sin^{-1} (0.8714) \approx 60.62^{\circ}[/tex]
Therefore, m∠M ≈ 60.62°
m∠M ≠ sin M ≈ 0.8714
Therefore;
Kimberly did not find the inverse sine (sin⁻¹) of the value she calculated

Bob and Sue are meeting on a stairway. Bob is at the top and Sue is at the bottom. There are 9 steps
from bottom to top. Bob can skip a step each time since he is going down, Sue will not skip any steps. On
which step will they meet.
Answer:
Bob is at the top, so he starts at step 9.
Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)
Sue climbs from one step on one step.
Then she if she climbs n times, she will be at the step number:
S(n) = 0 + 1*n
And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:
B(n) = 9 - 2*n
We want to see when they meet, then we need to solve:
S(n) = B(n)
1*n = 9 - 2*n
1*n + 2*n = 9
3*n = 9
n = 9/3 = 3
n = 3.
This means that they meet a the step:
S(3) = 3*1 = 3
B(3) = 9 - 2*3 = 9 - 6 = 3
They meet at the third steep.

Given the figure as marked. What is x?
Answer:
6
Step-by-step explanation:
Using the similarity theorem f the triangle
(4+6)/x+9 = 4/x
10/x+9 = 4/x
Cross multiply
10x =4(x+9)
10x = 4x+36
10x-4x = 36
6x = 36
x = 6
Hence the value of x is 6

Step-by-step explanation:
Leah has just inherited $12,000. She wants to invest the money so that she can increase the value of
her inheritance. What are some of the ways she can do this?
1. Leah wants to invest the $12,000 in an account that pays 4.5% annual interest.
a. Write equations for the amount A(t) that will be in the account after t years, if the interest is
compounded continuously, daily, and monthly. Then, find the amount after 10 years, rounded
to the nearest cent, for each method of compounding. Complete the table
When interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
If the interest compounded continuously:
P = $12000, r = 4.5% = 0.045%
[tex]\rm A(t) =12000(e)^{0.045t}[/tex]
When t = 10 years, plug this value in the above expression and calculating, we get;
A(10) = $18819.75
When interest compounded daily:
[tex]\rm A(t) = 12000(1+\dfrac{0.045}{365})^{365t}[/tex]
Plug t = 10 years:
We get;
A(10) = $18819.22
Similarly,
If interest is compounded monthly:
n = 12 and t =10, we get:
A(10) = $18803.91
Thus, when interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!!
Answer:
Step-by-step explanation:
Supplementary angles add up to 180°.
“θ is 148° more than its supplement”
Supplement of θ = 180°-θ
θ = (180°-θ) + 148°
2θ = 328°
θ = 164°
Supplement of θ = 180°-164° = 16°

The diameter of a circle is 24 meters. What is the circle's area? Use 3.14 for .
Answer:
To get the circumference, multiply the diameter by pi. You have the diameter in meters, and you were given an approximate value of pi. Multiply these 2 numbers, and get the circumference in meters.
Step-by-step explanation:
Answer:
144π or about 452.39
Step-by-step explanation:
Diameter = 24 meters
Radius = diameter/2 = 12 meters
Area of a circle = π*radius*radius = π*radius^2
Area = π*12^2 = 144π = 452.39
