.The value of cos(2x) is 1/8

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.

Given:

cos x = 3/4

Using identity,

cos 2x = 2 cos^2 (x)-1

=2(3/4*3/4)-1

=2*9/16-1

=9/8-1

=1/8.

Answer:

4:30 minutes im thinking

Step-by-step explanation:

The value is  30 minutes. Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the expression 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The expression that give us the distance that Tory has ride after t minutes is:

D = 880t

Because Tory rides at 880 feet per minute.

At the same way, the distance that Terrence has ride after t minutes is equal to:

D = 1056(t - 5)

Because Terrence rides at 1056 feet per minute and he starts out 5 minutes after Tory

Now, we need to find t when both expressions are equal, so we can formulate the following equation:

[tex]880t=1056(t-5)[/tex]

So, solving for t, we get:

[tex]880t=1056t - 1056.5[/tex]

[tex]880t=1056t - 5280[/tex]

[tex]880t=1056t =-5280[/tex]

[tex]-176t=-5280[/tex]

[tex]t=-5280/-176[/tex]

[tex]t= 30[/tex]

Therefore the answer is 30 minutes

Answer:

4 hours

Step-by-step explanation:

Let the size of  whole wall be x.

Given that

Ralph painted 1/6 of a wall in 2/3 hours

thus, writing it in mathematical form we have,

time taken to pain 1/6 of x = 2/3 hours

=>time taken to pain x/6 wall = 2/3 hours

since, we have taken size as x so to find time to pain x size of wall ,

we divide both side by 6

=>time taken to pain x/6 * 6 wall = 2/3 *6 hours

=> time taken to pain x wall = 4 hours

Thus, It will take 4 hours to paint whole wall

Answer:

B, (11/2,-6)

Step-by-step explanation:

to get the midpoint of two endpoints, simply take the average of each corresponding coordinate

midpoint: ((Rx+Sx)/2,(Ry+Sy/2)).

((9+2/2),(-4+-8/2)) = (11/2,-12/2) = (11/2,-6)

the midpoint formula in general is : ((x+x1)/2),(y+y1)/2))

where x1 is the initial or first x coordinate, y1 is the initial or first y coordinate, x is the second, last, or final x coordinate. and y is the second, last, or final y coordinate.

Answer:

Joey is 14, Billy is 10.

Step-by-step explanation:

The system of equations you can use is:

j=b+4

j+b=24

(b+4)+b=24

2b+4=24

2b=20

b=10

j=10+4

j=14

Answer: j+b=24

J=b+4

Step-by-step explanation: (b+4) + b=24

You’re going to substitue J=b+4 into j+b=24

you’re going to get joeys age 14, Billy’s age 10

Answer:

r=-2

Step-by-step explanation:

First, you need to combine like terms so now you have 12r-(-4)=-20. Then you have to subtract -4 to -20 which equals -24 so now you have 12r=-24. Finally, you divide 12 from both sides and you get r=-2

Answer:

r = -2

Step-by-step explanation:

20r + 11r - 19r + 4 = -20

12r + 4 = -20

subtract 4 from both sides of the equation

12r + 4 - 4 = -20 - 4

12r = -24

divide both sides by 12

12r/12 = -24/12

r = -2
