Answer:
15
Step-by-step explanation:
Let x be the number
3 times the number = 3x
7 more than 3 times a number = 3x +7
3x + 7 = 52
3x = 52 -7
3x = 45
x = 45/3
x = 15
Answer:
the object is in the air on the time interval (0.24 sec, 6.51 sec)
Step-by-step explanation:
The object is 'in the air' for all t such that h> 0. We need to find the roots of h = -16t^2 + 108t - 25 = 0. From the graph we see that both t values are positive. Once we find them, we subtract the smaller t from the larger t, which results in the length of time the object is in the air.
Use the quadratic formula to find the roots of h(t). The coefficients of t are {-16, 108, -25}, and so the discriminant b^2 - 4ac is
108² - 4(-16)(-25) = 11664 - 1600 = 10064, whose square root is 100.32.
Then the quadratic formula x = (-b ± √[b² - 4ac)/(2a) becomes
-108 ± 100.32 108 ± 100.32
t = ---------------------- = --------------------- = 3.375 ± 3.135
2(-16) 32
or t = 6.51 or t = 0.24 (both times expressed in seconds).
So, again, the object is in the air on the time interval (0.24 sec, 6.51 sec)
Based from the given
data, the expected number of cars sold in one week is B. 1.5.
The equation to solve
the problem would be like this. 0*1/8 + 1*3/8 + 2*3/8 + 3*1/8 = 3/2
which when simplified is 1.5.
