Answer:
21 miles per gallon.
Step-by-step explanation:
273 divided by 13 is equivlent to 21
A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
Answer:
Step-by-step explanation:
total profit=income -cost
or
P(x)=R(x)-C(x)=-0.5x²+800x-100-(300 x+250)
or P(x)=-0.5x²+800x-100-300x-250
or P(x)=-0.5 x²+500 x-350
so (2)
First you must write out the question (it may help to read it out loud)
14+x=17
Subtract 14 from both sides
x=17-14
Solve
x=3
Answer:
60°
Step-by-step explanation:
Since this is an equilateral triangle all the angles and sides are the same.
180÷3=60°
All the angLes will be 60°, because in a triangle ball angles must add up to 180°.
Hope this answers your question.
