Which of the following ratios are equivalent to 6:8?9:12
12 to 16
24:36
16 to 24

Answers

Answer 1
Answer: 12 to 16 should be the only one.
i looked over ti and 9/12 is also equivalent.
if you multiple by 1.5 that gets you 9/12

Regular Hexagon ABCDEF rotates 240' counterclockwise about its center to produce hexagon A'B'C'D'E'F'. Which points will A' and B' coincide within the pre image

Answers

Answer:

A' will coincide with C of the pre image, and B' will coincide with D of the pre image.

Step-by-step explanation:

A Regular Hexagon could be imagined as a circle divided into six points on the circle, that are separated by angles of 60° (notice that 6 times 60° is 360°).

Now we name each point as ABCDEF clockwise, and then we rotate the hexagon about its center (counterclockwise)... the original points ABCDEF are renamed as A'B'C'D'E'F' in the rotated hexagon.

As the rotation was of 240°, the points will coincide with some of the original points: point A will "jump" for points, the same as point B.

This means that point A rotated, (wich is A') will coincide with point C pre rotated, and that point B rotated, (wich is B') will coincide with point D pre rotated.

If an object is dropped from a height of 144 feet, the function h(t) = -16t2 + 144 gives the height of the object after t seconds. When will the object hit the ground? A) 9 seconds

B) 6 seconds

C) 1.5 seconds

D) 3 seconds

Answers

So this question is asking for the zeros, or the x-intercepts, of this equation. For this, we have to set h(t) to zero to solve for it.

For this, we will be using the quadratic formula, which is x=(-b+√(b^2-4ac))/(2a),(-b-√(b^2-4ac))/(2a) (a = t^2 coefficient, b = t coefficient, and c = constant). In this case, our equation is t=(-0+√(0^2-4*(-16)*144))/(2*(-16)),(-0-√(0^2-4*(-16)*144))/(2*(-16)) . From here we can solve for t.

  1. Firstly, solve the exponents and multiplications: t=(-0+√(0+9216))/(-32),(-0-√(0+9216))/(-32)
  2. Next, solve the additions and subtractions: t=(√(9216))/(-32),(-√(9216))/(-32)
  3. Next, square root 9216: t=(96)/(-32),(-96)/(-32)
  4. Lastly, divide and your answers are going to be t=-3,3

Since we cannot have negative time,the object hits the ground at 3 seconds, or D.

Evaluate the expression. -8÷-4

Answers

-8/-4 = 2

as negatives gets cancelled ! and 8/4 gives 2 !

Answer:

2 is the answer

Step-by-step explanation:

Find the slope of the line that contains these two points.
(2, -5) and (7, -10)

Answers

\sf Slope= (y_2-y_1)/(x_2-x_1)

Where \sf (x_1,y_1), (x_2,y_2) are the two points.

So

\sf Slope = ( -10-(-5))/(7-2)=(-10+5)/(7-2)=(-5)/(5)=-1

So the slope of (2,-5) and (7,-10) was \boxed{ -1}
m=(y1-y2)/(x1-x2)=(-5-(-10))/(2-7)=(5)/(-5) =-1
 Answer: slope is -1

Math help please!!!
**check picture below**

Answers

Simple...

(3x y^(3) )(2 x^(3)y)

3*2=6

x* x^(3)= x^(4)  (Exponents "multiplied" are added)

y^(3) *y= y^(4)

Making it...

6 x^(4)y ^(4)

Thus, the answer to your first question.

The Second One....

(x^(2) -2x-2)*( x^(2) +2x+3)

It looks hard, but it's not...break it down..

x^(2) * x^(2) = x^(4)

x^(2) *-2x=-2 x^(3)

x^(2) *2x=2 x^(3)

x^(2) *-2=-2 x^(2)

-2x*2x=-4 x^(2)

x^(2) *3=3 x^(2)

-2*2x=-4x

-2x*3=-6x

-2*3=-6

Now..FINALLY...add it up..

Making the answer to your second equation...

x^(4) -2 x^(3) +2x ^(3) -6x ^(2) +3 x^(2) -10x-6

x^(4) -3x ^(2)-10x-6.
