Suppose sin(x) = -3/5 and cos(x) < 0. What the value of cos(2x)?
A) -16/25
B) -7/25
C) 7/25
D) 16/25
Answer:
The value of cos(2x) = 7/25
Hence, option C is true.
Step-by-step explanation:
Using the trigonometric identity
cos 2x = 1 - 2sin²x
Given
sin(x) = -3/5cos(x) < 0so substituting the values
cos 2x = 1 - 2sin²x
= 1 - 2 (-3/5)²
= 1 - 2 (9/25)
= 1 - 18/25
= 7/25
Therefore,
The value of cos(2x) = 7/25
Hence, option C is true.

Answer: (2, -2)
x=2, y=-2
Answer:
(2, -2)
Step-by-step explanation:
4x + y = 6
x - 2y = 6
x = 2y + 6
4(2y + 6) + y = 6
8y + 24 + y = 6
9y + 24 = 6
9y = 6 - 24
9y = -18
y = -18 ÷ 9
y = -2
4x + (-2) = 6
4x - 2 = 6
4x = 6 + 2
4x = 8
x = 8 ÷ 4
x = 2
Confirm:
4x + y = 6
4(2) - 2 = 6
8 - 2 = 6
6 = 6 (Correct)

A website sells sweaters. The amount of sales p(c) varies directly with the number of customers c. Eight customers bought a total of $335 worth of sweaters. Which equation can be used to find the sales for c customers? p(c) = 41.88c p(c) = 4188c p(c) = 41.88c p(c) = 4188c
Answer: p(c) = 41.88c
Step-by-step explanation:
From the question, we are informed that a website sells sweaters and that the amount of sales p(c) varies directly with the number of customers c.
We are further told that eight customers bought a total of $335 worth of sweaters.
The equation that can be used to find the sales for c customers will be:
= 335/8
Therefore, the answer is p(c) = 41.88c
= 41.88

One morning, Muhammad's deli shop sells 15 sandwiches in 10 minutes. If the shop continues to sell sandwiches at the same rate, about how many sandwiches will the shop sell in 3/4 of an hour?
Answer:
68 sandwiches
Step-by-step explanation:
Given that,
A shop sells 15 sandwiches in 10 minutes.
10 minutes = (10/60) hour = (1/6) hour
In (1/6) hour shop sells 15 sandwiches
In 1 hour = 90 sandwiches
To find, no of sandwiches in 3/4 hours, multiply 3/4 by 90. So,
In 3/4 hour = [tex]90\times \dfrac{3}{4}=67.5[/tex] sandwiches
or
≅ 68 sandwiches
So, 68 sandwiches can be made in 3/4 hour.
