Answer:
270m^3
Step-by-step explanation:
Area of the base times Hight. 9*5= 45 area of base 45*6= 270m
Answer:
Step-by-step explanation:
As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise). Thus, the slope of this line is
m = rise/run = 4/2 = 2.
Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.
From this we get the point-slope form:
y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.
To find the acceleration of the bicycle rider, we are going to use the acceleration formula:
where
is the acceleration
is the initial speed
is the final speed
is the time
We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore,
,
, and
. Lets replace those values in our formula:
We can conclude that the acceleration of the bicycle rider 1 m/s^2

Step-by-step explanation:
Answer:
-x^2 - 7x + 4
Step-by-step explanation:
2x(x - 1) - 3x^2 - (5x - 4)
= 2x^2 - 2x - 3x^2 - 5x + 4
Adding like terms, we get:-
-x^2 - 7x + 4 (answer).
