Answer:
m = 7.25
Step-by-step explanation:
8m + 7 - 5 = 60
Evaluate like terms.
8m + 2 = 60
Isolate 8m.
8m = 60 - 2
Evaluate.
8m = 58
Find m.
m = 58 ÷ 8
m = 7.25
Answer:
dP/dt = 650t = 650(2 ) = 1,300 people/year
The rate of increasing of population at the end of the year 1992 is 1,300 people/year
Step-by-step explanation:
Given;
Population function as;
P(t) =325 t^2 + 28547
The rate of change of the population dP/dt at any given time can be given as;
Rate = change in population/change in time = dP/dt
dP/dt = 2×325t = 650t
Therefore, after 1992;
t = 1992-1990 = 2years
dP/dt = 650t = 650(2 ) = 1,300 people/year
The rate of increasing of population at the end of the year 1992 is 1,300 people/year
The scientific notation of 70, 030, 000.
To find the scientific notation of this value
<span><span>
1. </span>We first
move the period which separates the whole number from the decimal number which
is located after the numbers of the given value.</span>
<span><span>2. </span>We move it
in the very recent order number which is seventy million, seven and zero.</span>
<span><span>
3. </span>It becomes
7.003</span>
<span><span>4. </span>Thus we
count how many moves we did from the tens to the ten million order place.</span>
