Answer
0= -5
Step-by-step explanation:
6(n) = 6(n-1)+1
6n = 6n - 6 +1
0= -5
(i don't know if this is correct very sorry!!)
Answer:
One
Step-by-step explanation:
13/sin(55) = 12/sinC
sinC = 0.7561403486
C = 49.1, 130.9
Since 130.9+55 = 185.9 > 180
It will not form a triangle.
So only one triangle possible with angle 49.1° at C
Answer:
Radius = 7.21 feet.
Height = 21.63 feet
- to the nearest hundredth.
Step-by-step explanation:
Let the radius be r feet, then the height will be 3r feet.
So the volume = 1,178.1 = 1/3 π r^2 h
1.178.1 = 1/3 π r^2 3r
1/3 π 3 r^3 = 1178.1
π r^3 = 1178.1
r^3 = 1178.1/ π
r^3 = 375
r = 7.211 feet.
So the height = 3 * 7.211 ft
= 21.633 ft
Answer:
The value of x = 9
Step-by-step explanation:
∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse
∴ There is a relation between the ⊥ line and the two parts of the hypotenuse
∴ (⊥)² = multiplication of the two parts of the hypotenuse
∴ (6)²= 4 × x
∴ 36 = 4 × x
∴ x = 36/4 = 9
