Answer:
3.61 seconds
Step-by-step explanation:
The bird starts 50 feet in the air, so will come down to a height of 40 feet after 3.61 seconds.
We want to solve h = 40.
40 = -16t^2 +55t +50
16t^2 -55t -10 = 0
t = (55 +√(55^2 -4(16)(-10)))/(2(16)) = (55 + √3665)/32 ≈ 3.61060
The bird will be 40 ft above the ground the first time after about 3.61 seconds.
Smaller Number is S
Larger Number is S + 13
Smaller # + Larger # = 61
S + S + 13 = 61
2S + 13 = 61
2S = 61 - 13
2S = 48
S = 48/2
S = 24
Larger # = S + 13
Larger # = 24 + 13
Larger # = 37
Check. .. 24 + 37 = 61. CORRECT!
Smaller Number is 24
Larger Number is 37
Answer:
Step-by-step explanation:
Given that
S(x) stand for "x is smart".
Y(x) stand for "y is young".
C(x) stand for "x is a CS Major"
1) All CS majors are smart : C(x) ⇒ S(x)
2) Some CS majors are smart and not young.: There exists a∈C(x) such that a ∉ Y(x)
3) No young college students are CS majors.: ~Y(s)⇒CS(x)
