Answer:
Step-by-step explanation:
Given
z=119+120 i
Let
Squaring both sides
Comparing real and imaginary part
Re(LHS)=Re(RHS)
-----------1
comparing Im(LHS)=Im(RHS)
120=2pq
Substitute q in 1
Let
we take only Positive value because
x=149.85
thus
thus
Answer: 18 years
Work Shown:
The steps above show f(x) replaced with 5. Then you'd use logarithms to isolate the variable x. The relevant useful log rule is so we can pull down the exponent.
From here it seems your teacher wants you to round up to the nearest integer.
If we plugged in x = 17, then f(x) = 4.99 which is one cent too small.
While x = 18 leads to f(x) = 5.19
Therefore, x = 18 has the price reach or exceed $5

169/2209 OR 7.22%
Step-by-step explanation:
[probability that both have the secret decoder ring]=(13/47)*(12/46)
[probability that both have the secret decoder ring]=(156/2162)
[probability that both have the secret decoder ring]=0.0722-------> 7.22%
the answer is 0.0722 (7.22%)
Answer:
23 boxes filled
28 trains left over
Step-by-step explanation:
718 toy trains per day
each box holds 30 toys
718 / 30 = 23.93333
23 boxes will be filled
23 x 30 = 690 toys
^ boxes x toys per box = toys in boxes
718 - 690 = 28 left over toys
