Answer:
we have
(x,y). rotation through 90° anti-
clockwise about the origin(-y,x)
point (−8, 4) when rotated through 90° anti-
clockwise about the origin(-4,-8)
<u>Option.i. (−4, −8)</u>
Answer:
n the left cylinder, mix 5 ml of blue and 15 ml of yellow. This is a single batch of green.
Suppose you have one batch of green but want to make more. Which of the following would produce the same shade of green?
If you're unsure, try creating the mixture in the right cylinder. Start with the amounts in a single batch (5 ml of blue and 15 ml of yellow) and . . .
add 20 ml of blue and 20 ml of yellow
double the amount of blue and the amount of yellow
triple the amount of blue and the amount of yellow
mix a single batch with a double batch
double the amount of blue and triple the amount of yellow

<h3>What is a nuclear power plant?</h3>
A nuclear power plant is a plant that produces energy by the use of nuclear energy. In a nuclear plant we always have a nuclear fuel that is used in the plant. The fuel undergoes a fission reaction that enables the plant to be used for the production of electricity.
Now we know that a nuclear reaction is a case of exponential decay hence the y-intercept for this function is the decay constant of the function.
The time when the area will be safe again in the year 2086 because following the function;
f(x)=1000(0.5)^x/30 thus;
1000(0.5)^100/30
= 99.2 Kg

Answer:
C
Step-by-step explanation:
To find the x-intercept, set y to equal 0 and solve for the equation 0=-2x-2.
2=-2x
x=-1
x-int: (-1,0)
This eliminates choices B and D.
To find the y-intercept, set x to equal 0 and solve for y.
y=-2(0)-2
y=-2
y-intercept:(0,-2)
The only choice with both these values is C.
There will be an equal margin on either side of the picture. So two times the margin plus the width of the picture must equal the page width of 10.
so the margin will be (10-5 1/2)/2.
