please help quickly

Answers

7/8 divided 1/4 = (7/8)/(1/4) 
division is multiplication by the inverse 
inverse of 1/4 => 4/1
(7/8)*4 =28/8 = 7/2 = 3.5

Allison and her husband Noah both get in their cars and begin to drive at the same time. Allison starts 360 mi from their home and drives directly home at a constant rate of 50 mph. Noah starts at their home and drives away from the home at a constant rate of 40 mph. The system that models this situation is given, where d represents the distance from home, and t represents time, in hours. The solution to the system is (4, 160).

What is the correct interpretation of the solution to this system?

d = 360 - 50t
d =40t

A. Noah will be 160 mi from home and Allison will be 4 mi from home.

B. Allison and Noah will both be 160 mi from home after 4 h.

C. Noah will be 4 mi from home and Allison will be 160 mi from home.

D. Allison and Noah will both be 4 mi from home when they drive for 160 min.

Marco wrote the equation below. Cos ( -π /2) = cos ( 3π / 2)

Which statement best describes Marcos equation?

Answers

Answer:

It is true, because the cosine function has a period of 2π


Step-by-step explanation:

Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

Cos(\theta)=Cos(2\pi +\theta)


Taking \theta as -(\pi)/(2), (2\pi + \theta) is equal to  2\pi + (-(\pi)/(2))\n=2\pi - (\pi)/(2)\n=(4\pi-\pi)/(2)\n=(3\pi)/(2)

The equation is true!

Note: The cos function is even function


Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
