At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y  be the cities population. Write an exponential function showing the relationship between y and t. 
Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t
Raoul says that Function B has a greater initial value. Is Raoul correct?
Answer:
yes he is correct because if you where to graph B it would have a greater slope

An 18% tip is left on a $65 dinner bill. 5% tax is added (before tip). What is the total paid?
Answer: $79.95
Step-by-step explanation:
65 × 0.18 = 11.7
65 × 0.05 = 3.25
11.7 + 3.25 = 14.95
14.95 + 65 = $79.95

a baseball team has won 25 games and lost 12 games. if the baseball teams rate continue through a 148 game season, then how many games will they have won?
Answer:
100 games won
Step-by-step explanation:
1. 25 games won and 12 games lost is a total of 37 games
2. If you're comparing the 25 games out of 37 games won to a total of 148 games played and trying to find the number of games won you would multiply 25 times 148 divided by 37

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
Answer:
4[tex]x^{2}[/tex]-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4([tex]x^{2}[/tex] - 4x + 4) - 8 = 4[tex]x^{2}[/tex] - 16x + 16 - 8 = 4[tex]x^{2}[/tex] - 16x + 8.
Answer:
[tex]f(x) = 4x^2 -16x + 16[/tex]
Step-by-step explanation:
f(x)=4(x-2)² Simplify.
f(x) = 4x^2 - 16x + 16
Form f(x)=ax²+bx+c.
f(x) = 4x^2 - 16x + 16
The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
x = -4, 4
Step-by-step explanation:
Given graph in the attachment represents the function y = f(x)
Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.
Since, graph of the function touches and crosses at x = -4 and x = 4
Therefore, all real solutions of the function are x = -4 and x = 4

Step-by-step explanation:
hope this helps!
Answer:
0.16
Step-by-step explanation:
First let's convert 0.4% to a decimal.
0.4% = 0.004
So, 0.4% of 40 is just 0.004 times 40, which is 0.16.

2x – 3y = -5
у = х – 1
y=?
x=?
HELP
Answer:
Y = 1
X= -1
Step-by-step explanation:
Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1
X is 2 - y which is 3 will equal -1
Answer:
Step-by-step explanation:
2x – 3y = -5.........(i)
у = х – 1................(ii)
Multiply equation (ii) by 3,
3у = 3х – 3.......(iii)
Add (i) and (iii)
2x – 3y = -5
+
-3x + 3y = – 3
=
-x = -8
x = 8
put the value of x in eq (ii)
у = х – 1
у = 8 – 1
y = 7

Write the linear equation in slope-intercept form given the following:
(1, 4) ; slope=−2
Answer:
y = -2x + 6
Step-by-step explanation:
The y-intercept is where the line goes through the y-axis. So, you'd want to find the value of y when x is 0.

Jerry is saving his money. He started with $15.00. If he adds $10.00 to his savings
each month, how much will he have saved after 2.5 months?
Answer:
$40
Step-by-step explanation:
use y = mx + b
y = amount saved = ?
m = amount saved per week = $10
x = time (in months) saving = 2.5
b = money jerry started with = $15
plug in:
y = (10)(2.5)+15
y = $40

Jack and beth are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190. Beth sold of 5 rolls plain and 3 shiny for a total of $90. Find the cost of each roll of wrapping paper
Answer:
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20
Step-by-step explanation:
Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.
Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.
[tex]5x+8y=190\,\,\,(i)[/tex]
Beth sold of 5 rolls plain and 3 shiny for a total of $90.
[tex]5x+3y=90\,\,\,(ii)[/tex]
Subtract (ii) from (i).
[tex]8y-3y=190-90\\5y=100\\y=20[/tex]
Put [tex]y=20[/tex] in (ii)
[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]
Therefore,
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The GCF of 14x and 18xy
As we know, GCF is the greatest common factor.
The greatest common factor of 14 and 18 or
GCF(14, 18) = 2
And the greatest common factor of GCF of x and xy
= x
the greatest common factor of 14x and 18xy is:
= 2x
Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
