distance between (-2,4) and (-38,-156)

Answers

Answer 1

Answer:

d = 164

Step-by-step explanation:

- To find the distance between two points, we have to plug the values into the distance formula:

d = √(x2 - x1)² + (y2 - y1)²

d = √(-156 - 4)² + [-38 - (-2)]

d = √(-160)² + (-36)²

d = √(25600) + (1296)

d = √26896

d = 164

Find the value of x in the given right triangle

Answers

hi <3

you can use the sine rule in this.

first calculate the missing angle in the triangle.

we know the angles in a triangle sum to 180 so:

180 - 37 - 90 = 53

now, simply input these values into the sine rule

10/sin(53) = x/sin(37)

rearrange for x:

x = (10/sin53) x sin37

solve to get your answer of:

x = 7.5

hope this helps :)

Answer:

tanx=opposite side

       adjacent side

tan(37)=x

              10

x=tan(37)x10 (take cross multipication)

x=(0.753554)x10

x=7.53554

Which of the following represents the ratio of the short leg to the hypotenuse
in the right triangle shown below?

Answers

I believe the answer is C

The ratio of the short leg to the hypotenuse of the given triangle is 1:2

What is triangle?

A triangle is a polygon of three sides. In a right angled traingle we use some basic trigonometric formula. Depending upon the  ratio of sides of triangle we use six trigonometric formulas.

The shorter leg of the triangle is =hypotenuse × cos60° .

[Use the formula cosθ=base/hypotenuse]

Therefore, the shorter leg= hypotenuse/2      [∵cos60°=1/2]

∴ (shorter leg)/(hypotenuse)=1/2

So, Shorter leg: Hypotenuse=1:2.

Hence the ratio of the shorter leg to the hypotenuse is 1:2.

which of the following is an even function
f(x)=lxl
f(x)=x^3-1
f(x)=-3x
f(x)=3^ square root of x​

Answers

An even function is a function where positive and negative values of x give you the same result.

Where f(2) = f(-2) and f(3) = f(-3)

To formally check it, you need to evaluate f(-x) and see if you get the original function back.

Graphically, an even function is symmetrical over the y-axis.

The only graph here that does all of that is f(x) = |x|

what is 2t+10t-6t equaled to

Step-by-step explanation:

if 5t=5 then t is what number

Answers

Answer:

1

Step-by-step explanation:

5t = 5

divide equation by 5 to get rid of it

t = 1

Answer:   t = 1

This is because 5t means "5 times t". The t is a placeholder for a number.

To solve for t, we divide both sides by 5

5t = 5

5t/5 = 5/5

t = 1

Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.
