Step-by-step explanation:
if cos(x)=-1/4 and tan(x)<0 what is sin(2x)
By definition of tangent,
tan(x) = sin(x) / cos(x)
so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.
Recall the Pythagorean identity:
cos²(x) + sin²(x) = 1 → sin(x) = + √(1 - cos²(x))
Then
sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4
Recall the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Then
sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8

Step-by-step explanation:
y = 1/2x + 2
Answer:
the first one
remember. y=mx+b
mx= slope
b= y intercept
the slope is positive and the slope is rise over run. the y intercept is when the line the y axis (doesn't matter if it is negative or positive). this makes it a positive two
The spoke of a wheel is 35 cm. How far does the wheel travel in 1 rotation. Give your answer in meters and use pi = 22/7.
Answer:
2.2 m
Step-by-step explanation:
Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).
2 x (22/7) x 35cm
= 220cm
As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m

use prime factors to find hcf of 18 12 56
Answer:
2 to the power of six times 3 cubed times seven.
Step-by-step explanation:
The prime factors of 56 are 2 cubed times 7 and the prime factors of 18 are 2 times 3 squared The prime factors of 12 are 2 squared times 3.
A factor is a number that divides another number, leaving no remainder
The highest common factor of 18, 12, and 56 using prime factors is 2.
What is a factor?A factor is a number that divides another number, leaving no remainder
Example: 12 = 4 x 3 where 4 and 3 are the factors of 12.
We have,
18, 12, and 56
The factors of each number are:
18 = 2 x 9, 3 x 6, 18 x 1
So the factors of 18 are 2, 3, 6, 9, and 18.
12 = 2 x 6, 3 x 4, 12 x 1
So the factors of 12 are 2, 3, 4, 6, and 12.
56 = 2 x 28, 4 x 14, 7 x 8, 14 x 4
So the factors of 56 are 2, 4, 7, 8, 14, and 28.
Thus,
The highest common factor of 18, 12, and 56 using prime factors is 2.

Solution:
The ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats is, 1/4
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
Felipe makes 3 batches of dog treats

A student solves the following equation and determines that the solution is −2. Is the student correct? Explain.
3/a + 2 − 6a/a2 − 4 = 1/a − 2
Answer:
No, the student did not check the solution to the derived equation in the original equation.
No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.
No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.
Step-by-step explanation:
just did on edge good luck!
The student is wrong in his answer to the equation
3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.
3/a + 2 - 3 - 4 = 1/a - 2.
3/a - 1/a = 3.
2/a = 3.
a/2 = 1/3.
a = 2/3.
