Answer 1
Answer: Hey there! So because this is to many question rolled in one, Im only going to be answering your simplify questions.

Starting with

1: (2)/(5) √(5)
2: 44 √(7)
3: 8 √(17)
4: 2+2 √(3)

So i solved this by using our square root functions. For if you didn't know, the square root symbol is this: √

Hope this helps!

Which answers describe the end behaviors of the function modeled by the graph? f(x)=−3x+2−2

Select each correct answer.

As x increases without bound, f(x) approaches the line y=−2.

As x increases without bound, f(x) increases without bound.

As x decreases without bound, f(x) approaches the line
y=−2.

As x increases without bound, f(x) decreases without bound.

Answers

For the given function, as x increases without bound, f(x) decreases without bound. Option D is correct.

Given that,
To describe the end behaviors of the function modeled by the graph,
f(x)=−3x+2−2

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

Here,
The function given is,
f(x) = -3x + 2 - 2
Given function contains equality so the function has no boundaries and the function is described from negative infinity to positive infinity, But the function has inverse behavior as when x is negative the function is positive and when x is positive function is negative.

Thus, for the given function, as x increases without bound, f(x) decreases without bound. Option D is correct.

Isolate y in the equation 3x+2y=8

Answers

Subtract 3x
2y=-3x+8
Divide by 2
Y=-3/2x+4
3x+2y=8

=> '3x' should pass to the other side. ( negative )

2y = 8 -3x

=> 'y' should be left alone

y = (8-3x)/(2)

Solve for x.

Given the equation: (km / 3) - 2x = 4, it is essential to isolate x to obtain the expression to solve it. This is done below:

(km / 3) - 2x = 4

Adding 2x to both sides:

(km / 3) - 2x + 2x = 4 + 2x
(km / 3) = 4 + 2x

Subtracting 4 from both sides:

(km / 3) - 4 = 4 + 2x - 4
(km / 3) - 4 = 2x

Dividing 2 from both sides:

[(km / 3) - 4] /2 = 2x /2
[(km / 3) - 4] /2 = x
x = (km / 6) - 2

What is LK rounded to the nearest hundredth? show work if you canAlso what is JK TO THE nearest hundredth? show work if you can

Answers

LK is actually the opposite side. What you've also been given is the length of the hypotenuse and an angle (20 degrees).

We know that:

sin(β)=Opposite/Hypotenuse=O/H

This is because of the famous:

SOH CAH TOA

-----

We can solve the problem by writing down:

sin(20)=LK/8.5

This means that:

LK = 8.5 * sin(20)

LK = 2.91 metres (to 2 decimal places)

The midpoint of the sides of triangle ABC are labeled D, E, and F. If the perimeter of triangle DEF is 24 find the perimeter of triangle ABC.A.48
B.72
C.96
D.120

Answers

Ok well the only thing that makes since to me is that the triangle is a Equilateral Triangle, so all the sides are going to be the same. And if the perimeter is 24, then you divide that by 3, and you get 8. And if DEF is the midpoints of triangle ABC, then DEF is an upside down triangle in the triangle ABC. So all the sides of ABC are double whatever DEFs are. And DEFs were 8, so 8 times 2 is 16. And to get the perimeter you add that together 3 times and you get 48. So i'm not sure exactly how you would do this, but i'm pretty sure this is the way. If not i'm sorry i couldn't help. :(
Linking the midpoints of each side of a triangle cuts it into four smaller, mathematically similar versions of itself, the central of which is reflected vertically - ALWAYS. Therefore, the area scale factor of the new, smaller triangle to the original larger triangle, is 4. √(4) would give the linear scale factor (the nth route of the area scale factor, where n is the dimension of operation), which is 2.
The original triangle must have a perimeter twice as long as the smaller triangle.
