Answer:
x=3, y=2
Step-by-step explanation:
To solve by elimination method, multiply one of the equation by a constant such that when you subtract one equation from the other, you are left with one term only.
Doubling formula is this:
where P=initial number of rabbits
t=time
d=time it takes to doulbe
ok, so 4 weeks is the doubling time so that is 4*7=28 days
we wawnt time=98
and oroiginal number of rabbits is 5 so
so P(98)≈56.56
we can't have .56 rabbit so round down or up
about 56 or 57 rabbits in 98 days
Answer:
Width = 7, Length = 42
Step-by-step explanation:
Length is 6 times its width, means that it's the same number but times 6 so we'll use "x" for both length and width:
6x · x = 294
6x^2 = 294
divide both sides by 6
x^2 = 49
=
x = 7, width is 7 and length is 6(7) = 42
Answer:
The horizontal distance of the shot from the start is 24 feet and the height of the shot above the ground is 23.08 feet.
Step-by-step explanation:
we have
where
x represents the horizontal distance from the start in feet
h(x) s the height of the shot put above the ground in feet
Determine h(24)
That means ----> The height of the shot put above the ground for a horizontal distance of 24 feet from the start
substitute the value of x=24 ft in the quadratic equation
so
The horizontal distance of the shot from the start is 24 feet and the height of the shot above the ground is 23.08 feet.
A=1/2(h)(3/4h)
A=3/8h²
h²=8/3(A)
h=√8A/3
