Answer:
0.46 per donut. 46 cents
Step-by-step explanation:
5.49/12=0.4575
Rounding to the nearest cent is about 46 cents per donut.
Both the equation show a graph of a parabola. The equation y=-x^2+1 is a parabola opening downward since the x variable has a negative sign. While the equation y=x^2 is also a parabola opening upward since x^2 is positive. Both parabola have axis of symmetry on the y-axis. Vertex for the first parabola is on (0,1) while the second parabola is at the origin.
Answer:
6x^2-7x-20 (c)
Step-by-step explanation:
(3x+4)(2x−5)
=(3x+4)(2x+−5)
=(3x)(2x)+(3x)(−5)+(4)(2x)+(4)(−5)
=6x^2−15x+8x−20
=6x^2-7x-20
Answer:
64.5°
Step-by-step explanation:
angle of elevation is the angle from the point where the shadow ends. this create a right angle triangle. using tan, you can find the angle.
tan theta = opposite/adjacent
angle = tan^-1(42/20)
angle = 64.5°
