Answer:
find the slope then use this y-y1=m(x-x1)
Step-by-step explanation:
Answer:
£3182.7
Step-by-step explanation:
£3000=100%
? =3%
3×3000/100
=£90
£(3000+90)=£3090(1st year)
£3090=100%
? =3%
3×3090/100=£3182.7
Answer:
31
Step-by-step explanation:
$23.25 divided by $0.75 is 31.
Answer:
The y intercept is -1
Step-by-step explanation:
the y-intercept is when y = 0
f(0) = -2^2 + 4(0) - 5
f(0) = 4 - 5
f(0) = -1
For this case we have the following equation of motion:
h (t) = -16t ^ 2 + 90t
Equaling the equation to zero we have:
-16t ^ 2 + 90t = 0
We look for the roots of the polynomial:
(t) (- 16t + 90) = 0
t1 = 0 (initial position)
t2 = 90/16 = 5.625 s (time it reaches the ground again)
Answer:
it will return to the ground in:
t = 5.625 s
