Answer: y = (1/4)x - 1
Step-by-step explanation:
Slope intercept form is . The
-intercept is -1 so we have
. To find
, look at the points
and
. The line goes up 1 and over 4, so the slope,
, equals
. Thus the full equation is
.
Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
For this case we have the following polynomial:
What we must do for this case is to factor the polynomial, so that we have:
1) The number of bottles
2) the weight of each bottle.
We have then:
Answer:
A factorization that could represent the number of water bottles and weight of each water bottle is:
