Answer:

21/20, or 1.05.

Step-by-step explanation:

In this case, the measure of angle R is the same as angle V.

To find the tangent of a triangle, you do opposite over adjacent.

So, the tangent of angle V is 21 / 20.

That means that tan(R) = 1.05.

Volume of Spheres<br><br><br> Volume of Spheres
lukranit [14]

Answer:

V ≈ 2,048 ft^3

<u>Hope this helps :)</u>

Step-by-step explanation:

The symbol ^ means raised to a power.

Formula for Volume of Sphere - V = 4/3 π r^3

1. To find the volume of a sphere, first find the radius with the given diameter 16.

16 ÷ 2 = 8

Radius = 8

2. Substitute r for 8 and solve, and 3 will be used for π.

V ≈ 4/3 • 3 • 8^3

V ≈ 4/3 • 3 • 512

V ≈ 4/3 • 1536

V ≈ 6144/3

V ≈ 2,048

Given

The equation of the line y=4x-1 passes through the point (3,p)

So, point must satisfies the line i.e.

\Rightarrow p=4(3)-1\\\Rightarrow p=12-1\\\Rightarrow p=11

Therefore, the value of p is 11.
