Suppose the number of leaves z on a tree varies directly with the height of the tree y in yards and directly with the cube of th
1 answer:
Answer:
The number of leaves are 10648
Step-by-step explanation:
By the given information,
number of leaves be= z
height of tree= y
hours of sunlight= x
by the given conditions,
,where k is portionality constant.
now, z=6048, y=7 and x=6,
evaluating value of k using above conditions,
k=4
thus, using this value of k,
z= 10648.

Answer:
The equation in slope-intercept form that represents the situation is y=0.25*x + 84 where y represents the temperature in ° F and x the number of chirps per minute.
Step-by-step explanation:
A linear equation can be expressed in the form y=m*x + b. In this equation, x and y are coordinates of a point, m is the slope and b is the y coordinate of the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.
When there are two points of a line (x1, y1) and (x2, y2), the slope is determined by the quotient between the difference of the ordinate of these two points and the difference of the abscissa of the same points. This is:
Having a point on the line, you can substitute the values of m, x and y in the equation y = mx + b and thus find b.
In this case:
- (x1, y1): (92, 107)
- (x2, y2): (116, 113)
So:
m= 0.25
substituting the values of m, x1 and y1 in the equation y = mx + b you have:
107= 0.25*92 + b
107 - 0.25*92= b
84=b
