Answer:
common ratio:2 2. 18 3.36 4.72 equation: 4.5(
)
Step-by-step explanation:
144=2*2*2*2*3*3 9=3*3
the common ratio would be 2
2. 9*2=18
3. 18*2=36
4. 36*2=72
(check) 72*2=144
0. 9/2=4.5
equation: 4.5()
the standard form for a horizontal ellipse is
X^2/a^2 + y^2/b^2 = 1
Substitute 54 for b and and use (8,18) as the
point to find a
x=8
y=18
8^2/a^2 + 18^2/54^2 =1
64/a^2 + 324/2916 = 1
324/2916 reduces to 1/9
64/a^2 + 1/9 = 1
64/a^2= 1-1/9
64/a^2 = 8/9
64*9/8 = a^2
576/8 = 72
A^2 = 72
A = square root(72) = 8.485
So formula
would be x^2/72 + y^2/2916 =1
Answer: 0; -2
Step-by-step explanation:
Data: y-intercept=x and slope=x
Equation=y=-2
Only step, Point out the y-intercept and slope
-2=y-intercept
0=slope
Reason: Since there is no visible slope, the placeholder would be 0 therefore the slope would be 0, -2 is the only number left so that means the only number that can be y-intercept is -2.
That is why the slope is 0 and the y-intercept is -2
I hope this helps!
No it’s berry 2yards=6feet so they are all smaller than berrys 7foot fish
Percent that are girls = 100-40 = 60%
As a decimal 60% is 0.6.
