On a baseball field, the pitcher’s mound is 60.5 feet from home plate. During practice, a batter hits a ball 195 feet at an angl
worty [1.4K]

In this problem, we can imagine that all the points connect to form a triangle. The three point or vertices are located on the pitcher mount, the home plate and where the outfielder catches the ball. So in this case we are given two sides of the triangle and the angle in between the two sides.

<span>With the following conditions, we can use the cosine law to solve for the unknown 3rd side. The formula is:</span>

c^2 = a^2 + b^2 – 2 a b cos θ

Where,

a = 60.5 ft

b = 195 ft

θ = 32°

Substituting the given values:

c^2 = (60.5)^2 + (195)^2 – 2 (60.5) (195) cos 32

c^2 = 3660.25 + 38025 – 20009.7

c^2 = 21,675.56

c = 147.23 ft

<span>Therefore the outfielder throws the ball at a distance of 147.23 ft towards the home plate.</span>

What is the greatest common factor of the terms 14c to the second power D and 42 C to the third power d
irina [24]

Answer:


Step-by-step explanation:

To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,


So , The given two terms can be given by

14c^2d = 2.7.c.c.d\\42c^3d =2.3.7.c.c.c.d\\

Here common numbers that are in both are

2.7.c.c.d

so GCF= 14c^2d
