Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer
The number of goldfish in the pet store is equal to 60 fishes.
<u>Given the following data:</u>
- Total number of fishes = 150 fishes.
To calculate the number of goldfish that the pet store have:
<h3>What is ratio?</h3>
Ratio can be defined as an expression that is used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.
Mathematically, the number of goldfish in the pet store is given by this expression:

G = 60 fishes.

Answer:



Step-by-step explanation:
Given
Similar Triangles: ABC and DEF



Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.

Where

Assume n = 2.
So, we have:







Assume 
So, we have:







So, the possible sides are:



D=56t because if t is hrs then u would multiply 56 and t to find the miles per hour
