Answer: -12y²+7y²+20y-7

Step-by-step explanation:

Here, we need to use the concept of the FOIL method

  • First Outer Inner Last

----------------------------------------------------------

Given

 (-3y+1)(4y²-y-7)

Expand Parenthesis using FOIL

-12y³+3y²+21y+4y²-y-7

Put like terms together

-12y³+(3y²+4y²)+(21y-y)-7

Combine like terms together

-12y²+7y²+20y-7

Hope this helps!! :)

Mary is inscribing a square in the circle shown, but she is having difficulty remembering the process. Which summary describes t
Ivenika [448]

Answer:

C. Create the perpendicular bisector of FG. Then use the points of intersection of the perpendicular bisector with the circle, along with points F and G, to draw the square.

Step-by-step explanation:

The steps are below:

1. A diameter of the circle is drawn.

2. A perpendicular bisector of the diameter is drawn using the method described in the perpendicular bisector of a segment. This is also a diameter of the circle.

3. The resulting four points on the circle are the vertices of the inscribed square.

Can someone please answer. There is one question. There a picture. Thank you!
Anuta_ua [19.1K]
Ok so you need the surface area formula of a cone.

A = πrl +  πr∧2

where π = 3.14 (pi) 
           r = half of the diameter (18/2 = 9)
           l = slant hight ( 22 )
Slot this into the equation  A =  (3.14 [ rounded] )(9)(22) + (3.14 [ rounded] )(9)∧2 = 876.06 this is due to the rounded pi the answer is 876.5 i.e the third.

Hope this helps :D.

Find the domain of the function.<br> f(x)= x+2/1-X
Ymorist [56]

Answer:

all real numbers expect  1.

Step-by-step explanation: This is a rational function. when we  usually the find the domain of a rational function we would look at the bottom because you don't want the denomonatior to be zero because dividing by zero in math makes the range undefined. so we use the equation and set it up to zero to find the domain. 1-x=0 -x=-1, divide by -1 and we get  1.  So x can be any numbers expect 1. Interval notation: (-∞,1)∪(1,+∞)
