Graph best represents the equation y=-2x-2
Answer-D
Answer:
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
we have
substitute
step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians
Answer:
it's a trick question, it's still (-9,0)
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Firstly,
≤ or ≥ means closed circle, and
< or > means open circle
Now, let's solve the compound inequality:
x - 1 ≤ 7
x ≤ 8
and
2x ≥ 22
x ≥ 11
This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"
Looking at the choices, D is right.
You distribute a 3/4 wherever you see a v
Use PEMDAS order of operations (parenthesis, exponents, multiply, divide, add, subtract)
12*3/4(32*9/16-8)
12*3/4(18-8)
12*3/4(10)
9*10
=90
Hope this helps
