Answer:
1.4.5m/s^2
2.6.25m/s^2
3.15m/s^2
4.0.05m/s^2
Step-by-step explanation:
a=v-u
----
t
27-0
------ = 27/6
6
=4.5m/s^2
u=4.5m/s
v=24.5m/s
t=3.2s
(24.5-4.5)÷3.2
=20/3.2
=6.25m/s^2
v=80m/s
u=50m/s
t=2s
(80-50)÷2
15m/s^2
v=0.80m/s
u=0.50m/s
t=6s
(0.80-0.50)÷6
=0.05m/s^2
Answer:
Second option: (-2,-3) and (1,0)
Step-by-step explanation:
Given the system of equations
, you can rewrite them in this form:

Simplify:
Factor the quadratic equation. Choose two number whose sum be 1 and whose product be -2. These are: 2 and -1, then:

Substitute each value of "x" into any of the original equation to find the values of "y":

Then, the solutions are:
(-2,-3) and (1,0)
Answer:
Yes :)
Step-by-step explanation:
Answer:
<h2>$21000</h2>
Step-by-step explanation:
This problem is on simple interest calcultion
A=P(1+r*n)
where
A=accumulated amount (final)
P= principal amount (initial), $15,000
r=interest written as decimal, 8% = 8/100= 0.08
n=number of years, 5years
Substituting into the expression we have
A=15000(1+0.08*5)
A= 15000(1+0.4)
A=15000(1.4)
A=$21000
<h2>Hence the ending balance that lucy would pay is $21000</h2>
