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

Answer:
x = 4
Step-by-step explanation:
3(2x + 5) = 39
Distribute;

Subtract 15 from both sides;
6x = 24
Divide both sides by 6;
x = 4
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
Your Turn Given the slope 8 and y-intercept 2 write the
equation of the line.
y =
Answer:
y = 8x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = 2 , thus
y = 8x + 2 ← equation of line

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.

15x + 5y = 20 y = 8 - 3x
Answer:
Step-by-step explanation:
15x+5y=8-3x
18x+5y=8⇒eqn 1
15x+5y=20y
15x-15y=0⇒eqn 2
eqn 1 * 3
54x + 15y=24⇒eqn 3
eqn 3 + eqn 2
69x=24
x=24/69=0.3478
eqn 1⇒
5y=8-18(24/69)
y=1.7391/5
y=0.3478
The solution to the system of equations is (10/3, -2).
What is an equation?Two or more expressions with an equal sign are defined as an equation.
The given equations are 15x + 5y = 20 and y = 8-3x.
15x + 15y = 20
Substitute y = 8-3x into the above equation:
15x + 15(8-3x) = 20
15x + 120 - 45x = 20
45x - 15x = 120 - 20
30x = 100
x = 10/3
Substitute x = 10/3 in y = 8 - 3x:
y = 8 - 3 (10/3)
y = 8 - 10
y = -2
Hence, the solution to the system of equations is (10/3, -2).

You are measuring temperature using a thermometer that gives degrees in Fahrenheit. You want to know what the temperature is in degrees Celsius. This formula converts temperatures from degrees Celsius to degrees Fahrenheit: F = 9/5 C + 32. Rewrite this formula to convert Fahrenheit to Celsius. In your answer, use fractions instead of decimal numbers.
Answer:
C = 5/9(F - 32)
Step-by-step explanation:
Given:
F = 9/5 C + 32
Convert Fahrenheit to Celsius:
Computation:
F = 9/5 C + 32
F - 32 = 9/5 C
5[F - 32] = 9C
C = 5/9(F - 32)

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.
