Answer:
(2,4) is the solution of the equation.
Step-by-step explanation:
Basically, the solution is the two points intersecting at a point. So, (2,4) is the solution of the equation.
Hoped this helped.
Answer:
c
Step-by-step explanation:
cause if you do both it will be the same answer with is also called commutatative
1/4+ (-3/4) = -0.5
-4 1/2 +2= -2.5
-8+ (-11/8)= -9.125
Answer:
Volume = V= 346.43 cm ^3
Step-by-step explanation:
15.32 x 10 = 153.2cm Area of side
We find the height of the cylinder, to enable the radius/2 for the circle side x 2
it would be the same as triangle side 6 but the exact circumference is worked out at 6.37
We start by finding the side
As a = half circumference = 20 x sin (30) =10 we x2 for full circumference, then divide by pi
10 +10 =20cm circumference.
20/6.28 =3.1847133758 = radius
we x 2 and find the height
3.1847133758 x 2 = 6.3694267516
rounded to nearest 10th = 6.4 units exact 6.37
We find other measurements before calculating volume.
and b = √400-√100 = √300
b= 17.32 (height for volume use) or length of right side cylinder
c= 20 hypotenuse.
Volume = πr2h
V= 3.14 * 6.37 * 17.32 =346.43
V= 346.43 cm ^3
V= 346 cm ^3 to nearest 10th
V= 346.43 cm^3
The formula of the area of the circle:
π × radius^2
In this case, given that the radius is 14 inches:
π × 14^2
=196π square inches
Therefore the answer is 196π square inches.
Hope it helps!
