Answer:
It's a parabola
Step-by-step explanation:
If you write the equation as
x =3y2
, you can see that you are in the form
f
(y)=3y2
. This is a quadratic polynomial in
y
, which means that it represents a parabola with axis parallel to the
x axis.
Answer:
∠?=40°
Step-by-step explanation:
Remember that in a line AND a triangle there are <u>180 degree</u>s.
You correctly found the third angle in the left triangle to be 69°, Now plug it into the equation for a line, including 71°:
<u>69°+71°+x=180°</u>
1) Combine the degrees:
140°+x=180°
2) Subtract 140° from both sides:
x=40°
We have now found the bottom left angle for the triangle on the right to be 40°
To find the angle labeled "?" You must plug in all of the known angles of the triangle to be equal to 180°:
40°+100°+x=180°
1) Combine the degrees:
140°+x=180°
2) Subtract 140 from both sides:
∠?=40°
0.161 (they said explain it so)
Reasonable because the three items altogether cost about $40
Answer:
P = ( 4y + 6 inches) + ( 8y - B ) inches + ( 5y + 3 ) inches
Step-by-step explanation:
Formula of Perimeter of triangle is = Sum of all sides.
P = A + B + C
