ABCD and PQRS are rectangles. O is the centre of both rectangles. AC is a straight line passing through P, Q and R. BD is a straight line passing through Q, R and S. PQ=8cm and QR=2cm. The perimeter of rectangle ABCD is 60cm. Work out the length of AB and the length of BC.
Answers
Answer: See below
Step-by-step explanation:
ΔPQR ≈ ΔABC because PR & AC are same line
So PQ ║ AB & QR ║ BC
In equation form: PQ / AB = QR / BC
8/AB = 2/BC
AB = 4BC
Perimeter of ABCD rectangle = 2(AB + BC)
= 2(4BC + BC)
= 10BC
Perimeter of the rectangle = 60 cm
In equation form: 10BC = 60
BC = 6 cm
AB = 4BC = 24 cm
Length of AB = 24 cm & length of BC = 6 cm

Show why x−3 is a factor of m(x)=x3−x2−5x−3. Justify your answer. You can show this using remainder theorem, long division, synthetic division or any method you choose.
Answers
The factors of a polynomial function are the zeros of the function
It is true that x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3
How to show why the x - 3 is a factorThe function is given as:
m(x) = x^3 - x^2 - 5x - 3
The factor is given as:
x - 3
Set the factor to 0
x - 3 = 0
Solve for x
x = 3
Substitute 3 for x in the function
m(3) = 3^3 - 3^2 - 5(3) - 3
Evaluate
m(3) =0
Since the value of m(3) is 0, then x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3

Step-by-step explanation:

Answers
Answer:
1: B
2: H
3. C or D (it's hard to tell, especially without an equation)
4. J
5. A
6. G
7. B
Step-by-step explanation:
1:
f(x) - g(x)
(x^2 + 8x) - (3x - 5) Distribute the negative
x^2 + 8x - 3x + 5 Combine like terms
x^2 + 5x + 5
2:
f(g(x))
Plug g(x) into f(x)
(2x - 1)^2 - 3
Immediately we can see that there will be a 4x^2 (because 2x times 2x = 4x^2) so we know the answer will be H because that's the only option with 4x^2
3:
The line starts at -4 on the x axis and goes infinitely to the right so everything greater than (and maybe equal to) -4.
On the y axis, the line starts at 0 and goes infinitely up so everything greater than (and maybe equal to) 0.
4:
To find the inverse of a function:
f(x) -> y
Switch x and y
Solve for y again
x = 3 +5y
x-3 = 5y
(x-3)/5 = y
5:
If option A were inverse functions, h(x) would be
x = 2y + 9
x - 9 = 2y
(x-9)/2 = y
Which could also be written as (1/2)x - 9/2 or (1/2)x - 4.5 but not (1/2)x - 9
6:
As y approaches -1, x approaches 1. Going the other direction,
As y approaches positive infinity, x approaches positive infinity.
7:
The number inside directly affecting the x moves the function left and right (left is positive, right is negative). The number outside moves the function up and down. So (x + 4) moves it left 4 and the +1 moves it up 1.

Answers
Answer:
71°
Step-by-step explanation:
Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary
since the sum of supplementary angles is equal to 180° :
180 - 109 = 71 is the measure of the co-interior angle

If John takes 2 hours to travel 20km,how many kilometers does he travel in 6 hours?
Answers
Answer:
60km
Step-by-step explanation:
There are two ways to look at this
1. Finding the unit rate
We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.
2. Multiply by 3
We can multiply both the km and hours by 3, since 2x3=6 hours
20km * 3 hours = 60km
2hrs 20km
6hrs. ?km
6x20 = 2?
120 =2?
120/2=?

R560 invested at 8% p.a. simple interest for 3 years

Answer:
R 694.4
Explanation:
simple interest = [tex]\sf{\dfrac{PRT}{100}[/tex] → [tex]\sf \dfrac{560*8*3}{100}[/tex] → R 134.4
where p refers to principal, r refers to rate, t refers to time.
total money:
invested money + simple interest
R 134.4 + R 560 → R 694.4
Answer:
R 694.40
Step-by-step explanation:
Simple interest formula:
A = P(1 + rt)
where A is the final amount, P is the initial principal balance, r is the annual interest rate (in decimal format), and t is time (in years)
Given:
P = 560r = 8% = 0.08t = 3⇒ A = 560(1 + 0.08 · 3)
⇒ A = 560(1.24)
⇒ A = 694.40

Answers
Answer:
82 cm^2
Step-by-step explanation:
First, find the formulas for the areas of all of the shapes shown
area of rectangles = base * height
area of triangle = 1/2 * base * height
for the triangle at the top, area = 1/2 * 5 * 2 = 5 cm^2
for the bottom triangle, area = 1/2 * 5 * 2 = 5 cm^2
for the left rectangle, area = 6 * 3 = 18 cm^2
for the middle rectangle, area = 5 * 6 = 30 cm^2
for the right triangle, area = 4 * 6 = 24 cm^2
add all of these together
5 + 5 + 18 + 30 + 24 = 82 cm ^2
which equals 15 ? when y=3 and x= 1/2

5x - 7 < 13
Answers
Answer:
5x-7 has to equal to something smaller than 13
5x-7=5
Answer: x < 4
Step-by-step explanation:
Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.
5x-7<13
5x<20
x<4
And so, our answer is x<4
