Answer:
The answer is A.
Step-by-step explanation:
A. 3*(-9)= -27, 4*(-9)= -36, -27-(-36)= 9
B. 3*(-27)= -81, 4*(-9)= -36, -81- (-36) = -45
C. 3*3= 9, 4*9= 36, 9-36= -27
D. 3*(-3)= -9, 4*(-6)= -24, -9-(-24)= 15

Answer:
D
Step-by-step explanation:
Volume of a cylinder is equal to the area of the base circle times the height of the cylinder.
The area of your base circle is 
where r=15 and they are using 
as 3.14.
So we have the area of your base circle is 
inches squared.
Now to find the volume of a cylinder again you just multiply your base area by your cylinder and you get:
cubic inches
Answer:
yes
Step-by-step explanation:
when 6 and 5 intersect it makes a ninty degree angle which is also known as a right angle and since its a triangle it simplifies to a right triangle. Sorry if i am wrong but im pretty sure im right lol
Answer:
they are equal
Step-by-step explanation:
Consider the right triangle ABC with sides a, b, and c as shown in the figure.
Let m(\angle A)=\alpha, and m(\angle B)=\beta.
\alpha +\beta=90^{\circ}, so angles A and B are complementary.
According to the definition of sine, and cosine:
\displaystyle{ \sin \alpha= \frac{opposite\ side}{hypotenuse} =\frac{a}{c} , and
\displaystyle{ \cos \beta= \frac{adjacent\ side}{hypotenuse} =\frac{a}{c}
