let <ACB=<C,
Here h=26 due to opposite to right angle is hypotenuse and b=10 Is a base and p=24 due to opposite to the angle <C
so,
Cos<C=b/h
=10/26
=5/13
Answer:
what do you need help with?
For this case we have the following function:
n (t) = 2400 * (5) ^ t
For n (t) = 60000 we have:
60000 = 2400 * (5) ^ t
We clear the value of t.
For this we use the logarithm:
(5) ^ t = 60000/2400
log5 ((5) ^ t) = log5 (60000/2400)
t = log5 (60000/2400)
t = 2 days
Answer:
the number of bacteria in the culture will be 60 comma 000 after:
t = 2 days
Answer:
2600 into the account earning 1% interest
2400 into the account earning 6% interest
Step-by-step explanation:
let x= account earning 1% interest
y= account earning 6% interest
we can write
x+y=5000 (equation 1)
.01x+.06y=170 (equation 2)
mulitply equation 1 by .01
.01x+.01y=50
subtract this from equation 2
(.01x+.06y)-(.01x+.01y)= 170-50
.05y= 120
y= 2400
Plug in y= 2400 into equation 1
x+2400=5000
x=2600
N^2 = 24 + 2n
n^2 - 2n - 24 = 0
(n-6)(n+4) = 0
n = 6 , n = - 4
