Answer:option D is the correct answer

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle,

The hypotenuse of the right angle triangle is 8

With m∠60 as the reference angle,

The adjacent side of the right angle triangle is 4

The opposite side of the right angle triangle is 4√3

To determine Cos 60, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos 60 = 4/8 = 1/2

To determine Tan 60, we would apply the Tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan 60 = 4√3/4

Tan 60 = √3

How do I solve 2x+x(x+6)

Mrac [35]

Step-by-step explanation:

Maths is simple

$2x + x(x + 6)$

expand the bracket

$2x + {x}^{2} + 6x$

then you add like terms 2x to 6x givind you

${x}^{2} + 8x$

this is how you solve it

i have to get the right question

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

5x - 2y = 9

3x + 4y = -5

Step 2: Rewrite systems

10x - 4y = 18

3x + 4y = -5

Step 3: Solve for x

Add to equations together: 13x = 13
Divide 13 on both sides: x = 1

Step 4: Solve for y

Define: 3x + 4y = -5
Substitute in x: 3(1) + 4y = -5
Multiply: 3 + 4y = -5
Isolate y term: 4y = -8
Isolate y: y = -2

And we have our final answer!

What does X represent in the equation Negative x / 5= 9

Inessa [10]

Answer: -X = (-) -45

Step-by-step explanation: because you can not divide a negative by a positive and get a positive you have to put a double negative on the x to make the 45 positive

In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in

wel

Answer:

Step-by-step explanation:

For Logan:

Logan swam 750m

Logan distance = 750m

Time taken = 1.3×3600

Time taken = 4680

Logan average speed = distance/time

average speed = 750/4680

Logan Average speed = 0.160m/s

Mila swam 2.3 of Logan's distance

Milan distance = 1725m

Time taken = 1.4×3600

Time taken = 5040s

Milan average speed = distance/time

Milan average speed = 1725/5040

Milan average speed = 0.342m/s

Comparing Milan speed with Logan speed:

Difference in speed = 0.342-0.160

Difference in speed = 0.182m/s

This means that Milan speed is 0.182 greater than Logan speed.
