Answer:
In 2012 the population of the city reach 457 thousand.
Step-by-step explanation:
We are given with equation A= 265[tex]e^{0.039t}[/tex]
Here it is given that A is 457.
So, plug in A as 457 and solve for 't'.
457= 265[tex]e^{0.039t}[/tex]
Divide both sides by 265.
1.7245283 =[tex]e^{0.039t}[/tex]
Now, take natural log on both sides,
ln(1.7245283)= ln([tex]e^{0.039t}[/tex])
0.5449535= 0.039t
Divide both sides by 0.039
t=13.97...
So, 't' is years after 1998.
So, 1998+13.97 =2011.97...
If we round to nearest years, we do get 2012.

The volume of gas varies inversely with the pressure exerted. If the volume is 3.5 liters when the pressue is 5, find the volume wihen the pressure is 8.
Answer:
v = k/p
where k is constant
3.5 = k/5
k = 3.5 × 5
k = 17.5
v = 17.5/p
v= 17.5/8
v = 2.1875
v ≈ 2.20 litres

Betty babysat for 3 hours each night for 12 nights. She earned a total of $288 babysitting. Betty wants to calculate her hourly rate. How much did Betty earn per hour babysitting?
Answer:Betty earned $8 per hour babysitting
Step-by-step explanation:
Number of hours worked per day =3
Number pf nights worked =12
Number of hours wored for 12 nghts =3x12=36hours
Now if 36 hours earned her $288
1 hour will earn her=( 288 x 1) / 36 = 8 hours
How can we use 40% to help calculate 4%? 400% 1%?
Answer:
To help find a percent of a whole number
1. out output value is 400
2. we represent the unkown value with x
3. from step 1 above 400=100%
4. similarly, x=40%
5. This results in a pair of simple equations
400=100%(1)
x=40%(4)
6. By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
[tex]\frac{400}{x} = \frac{100}{40}[/tex]
7. Again, the reciprocal of both sides gives
[tex]\frac{4}{400} = \frac{40}{100}[/tex]
⇒ x=160
Therefore, 40% of 400 is 160

solve the system of equations 9x-9y=-9 and 4x-3y=-8 by combining the equations PLEASE HELP QUICKLY!!!!!
9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
4x²+3y²-7xy+12x-11y+8=0 is your equation.

4. What is the area of the figure at the right?
Answer: 336
Step-by-step explanation:

12 * 10 = 120 / 2 = 60
12 * 18 = 216 / 2 = 108
60 + 60 + 108 + 108 = 336

Titan put $3,400 in a savings account at a local bank. The bank will pay him 1.9% annual simple interest. How much interest will Titan earn after 4 years?
Answer: $258.40
Step-by-step explanation:
The formula to calculate the simple interest will be:.
= Principal × Rate × Time
where,
Principal = $3400
Rate = 1.9%
Time = 4
Interest = $3400 × 1.9% × 4
= $3400 × 0.019 × 4
= $258.40

On the line that passes through point C, mark a point D that is distinct from point C. Use the slope formula along with coordinates of points to find the slopes of and . Show your work.
Answer:
PLATO
Step-by-step explanation:
Answer:
The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.
A = (-3, 3), B = (-1,-1)
Slope of AB = (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2
D = (-1,6), C = (1,2)
Slope of DC = (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?
Answer:
12 ft
Step-by-step explanation:
Using formula (pythagorean theorem)
a² + b² = c²
Where :
13 = c
and 5 = a
5² + b² = 13²
25 + b² = 169
169 - 25 = b²
144 = b²
Sq root b = 12
It will reach up 12 ft.
