-3•-4=12, and -3+-4=-7.
this will turn into
(x-3)(x-4)
set them up to equal zero
x-3=0, x-4=0
solve
x=3, x=4
(a)
Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin
This in standard form is -28x + 10.
The amount $600 would be after 3 years at 8% interest compounded continuously is $755.83
<h3>How to calculate compound interest?</h3>
Compound interest are amount of money added on amiunt invested.
Given the following parameters
P = $600
r = 8% = 0.08
t = 3 years
Using the compound interest formula
A(t) = Ao(1+r)^t
A(t) = 600(1.08)^3
A(3) = $755.83
Hence the $600 would amount to after 3 years at 8% interest compounded continuously is $755.83
