Answer:
B. x = 2√11
Step-by-step explanation:
The square of the length of the diagonal is ...
d² = 6² + 8² = 36 +64 = 100
Then the length of x is found from ...
d² +x² = 12²
x² = 144 -100 = 44 . . . . . subtract d²
x = √44 . . . . . . take the square root
x = 2√11
There are 8 triangles in this circle
An entire circle = 360 degrees
360/8=45
So I think the answer should be 45%
Answer:
Step-by-step explanation:
If she was given a discount of 12% then the amount to be paid becomes I=P×R×T/100
I=400000×12×20/100
I=960000
Amount to be paid =I +P= 960000+400000=1360000
To liquidate this amount in 20 years therefore will be A÷20
1360000÷20
=68000 yearly
Answer:
$62,000
Step-by-step explanation:
There are 20 people.
You have to add $5000 and $1200, which equals $6,200.
You have to multiply that by 10 to get the answer.
For q(x) = -2x - 2 and r(x) = x^2 + 2
Find the value of q(r(3)).
This is a problem that asks for you to find a function of a function. First things first, you must understand that it is asking you to plug r(3) into q(x) as the value of x.
Let's start by plugging 3 into r(x). Doing so, you'd get
r(3) = 3^2 + 2
Solve it.
r(3) = 9 + 2
r(3) = 11
You can see now that q(r(3)) is really q(11). Plug it in.
q(r(3)) = -2(11) - 2
Solve it.
q(r(3)) = -22 - 2
q(r(3)) = -24
