We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
Answer:
y=-8
Step-by-step explanation:
From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.
y=0x+b
We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.
-8=0(5)+b
Now just solve for b.
-8=0+b
b=-8
We now know that b is -8 and can complete the equation.
y=0x-8
y=-8
The answer is definately A
Answer:
z=70 degrees y=117 degrees
Step-by-step explanation:
To find angle z, you have to know that when two sides are against each other, they have to equal 180 degrees so 180-110 is equal to 70. Therefore z is equal to 70 degrees. To find y, you have to know that a quadrilateral's total degrees is equal to 360 degrees. Therefore, you have to do 360-93-80-70 which is equal to 117 degrees. Therefore y is equal to 117 degrees.
