Consider the population of a small town that grows according to the explicit rule: p = 53600 + 145 n, where n is the number of years after 2009. based on this model what is the population in 2022?
Answer:
p = 55485
Step-by-step explanation:
p = 53600 + 145 n
n = 2022 - 2009 = 13 years
so, p = 53600 + 145(13)
p = 55485
The figure shows rectangle RSTW. Which of the following conditions satisfies the criteria for rectangles?
a. m∠SRZ = 40°
b. m∠STZ = 40°
c. m∠SRW = 80°
c. m∠TWR = 80°
For the given rectangle RSTW, the condition satisfies the criteria of rectangles is equal to m ∠SRZ = 40°.
As given in the question,
In the given figure of rectangle RSTW,
Conditions satisfies the criteria of the rectangles are as follow:
a. m ∠SRZ = 40°
Line segment SR is parallel to TW. TR is the transversal.
m ∠SRT = m ∠WTR ( Alternate interior angles)
T -Z - R
m ∠SRZ = m ∠WTZ = 40°
Given criteria is satisfies the criteria of rectangles.
b. m ∠STZ = 40°
All the interior angles of rectangle are of measure 90°
m ∠STW = 90°
m ∠WTZ = 40° (given)
m ∠STZ + m ∠WTZ = 90°
⇒ m ∠STZ = 50°
Given option does not satisfies the criteria of rectangles.
c. m ∠SRW = 80°
All the interior angles of rectangle are of measure 90°
Given option does not satisfies the criteria of rectangles.
d. m ∠TWR = 80°
All the interior angles of rectangle are of measure 90°
Given option does not satisfies the criteria of rectangles.
Therefore, for the given rectangle RSTW, the condition satisfies the criteria of rectangles is equal to m ∠SRZ = 40°.

The tax amount to the nearest cent:$6.478
What is Tax?
Tax is the sum of money that citizens hand up to the government in exchange for goods and services. A taxpayer and a tax collector are both partners in any tax transaction. An entity that pays taxes to the government is referred to as a taxpayer. Any middleman that collects taxes on the government's behalf, including the government, is a tax collector.
Given,
The price of Rare gem = $82.00
The sales tax = 7.9%
Converting percent into decimal
7.9 / 100 = 0.079
The amount of sales tax = 82 x 0.079
= $6.478
The Total amount of the gem before the sales tax:

The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 3.5% per year for 30 years is $3,075.00. With a principal of £1,500.00 and an interest rate of 3.5% over a 30-year period, Sarah-Jane will save UK £1,575.00. It is undoubtedly a wise investment because the original UK £1,500 doubled.
What is Simple Interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principal, and the number of days between payments are multiplied to calculate simple interest.
What is the formula for Simple interest?A = P(1 + RT)
A=Final Amount
P = Principal
R = Rate of Interest
T = Time period
Here,
A = $3,075.00
I = A - P = $1,575.00
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 1500(1 + (0.035 × 30)) = 3075
A = $3,075.00
$3,075.00 is the total amount accrued from simple interest on a principal of $1,500.00 at a rate of 3.5% per year for 30 years (principal plus interest). In a 30-year loan with a £1,500.00 principal and a 3.5% interest rate, Sarah-Jane will save UK £1,575.00. The original UK £1,500 doubled, so it is unquestionably a smart investment.

[tex]g(f(\text{x})) = -3\text{x}^2+3[/tex]
[tex]g(f(2)) = -9[/tex]
=======================================================
Explanation:
Let's compute g(f(x))
We do this by starting with the outer function g(x). Then replace every x with f(x). Then plug in the definition of f(x) as shown below.
[tex]g(\text{x}) = \text{x}-1\\\\g(f(\text{x})) = f(\text{x})-1\\\\g(f(\text{x})) = 4-3\text{x}^2-1\\\\g(f(\text{x})) = -3\text{x}^2+3\\\\[/tex]
At this point, we then plug in x = 2 so we can find that...
[tex]g(f(\text{x})) = -3\text{x}^2+3\\\\g(f(2)) = -3(2)^2+3\\\\g(f(2)) = -3(4)+3\\\\g(f(2)) = -12+3\\\\g(f(2)) = -9\\\\[/tex]

Part a
A formula in terms of x and y for dy/dx
We differentiate equation that relates x and y with respect to x by implicit differentiation:

=> 45 *(1/3) x^-2/3 y^2/3 + 45 x^1/3 2/3 y^ -1/3 dy/dx=0
=> x^-2/3y^2/3+ 2 x^1/3 y^-1/3 dy/dx=0
=> y/x= -2dy/dx
=> log y = -2 log x +log c
=> y= x^ -2 +c
putting x=y=1

3/5 = 27/45 after multiplying top and bottom by 92/9 = 10/45 after multiplying top and bottom by 5So,

Danae is choosing between two jobs. One job pays an annual bonus of $1,500 plus $120 per day worked. The second job pays an annual bonus of $2,500 plus $110 per day worked. Which equation can be solved to determine after how many days, d, Danae would make the same amount of money regardless of the job she chooses?
a.) 120d + 110d = 1,500 + 2,500
b.) 120 + 110 = 1,500d + 2,500d
c.) 120d + 1,500 = 110d + 2,500
d.) 120d + 2,500 = 110d + 1,500
The equation that can be solved to determine the number of days when both jobs would have the same cost is 120d + 1,500 = 110d + 2,500.
What is the equation?The equations that would be formed would be linear equations. A linear equation is an equation that has a single variable that is raised to the power of one. A linear equation is a straight line when it is drawn on a graph.
The equation that represents the total bonus of the first job is: fixed pay + total variable pay
1,500 +( $120 x d)
1,500 + 120d
The equation that represents the total bonus of the second job is: fixed pay + total variable pay
$2,500 + ($110 x d)
$2,500 + $110d
When the amount at both jobs are equal, the two above linear functions would be equal
$2,500 + $110d = 1,500 + 120d

$2,500 - $1,500 = $120d - $110d
