In 1995, the population of a town was 33,500. It is decreasing at a rate of 2.5% per decade.
a. Identify whether the function is a growth or decay function.
b. Write the function, f(n), that expresses the population of the town after (n) decades.
c. What is the population in the year 2025 to the nearest hundred?
Answer:
See belowStep-by-step explanation:
Initial date = 1995Initial population = 33500Decrease rate = 2.5% per 10 yearsa. It is a decay function as number of population is decreasing over time
b. f(n) = 33500*((100 - 2.5)/100)^n = 33500*(0.975)^n
c. In year 2025, n = (2025 - 1995)/10 = 3
f(3) = 33500*(0.975)^3 = 31100 rounded up
Which of the following equations is the correct representation of the graph below?
1.Encuentra la ecuación de la circunferencia que tiene como ecuación ordinaria (x-4)² + (y+5)²= 25 2- encuentra la ecuación general de la circunferencia que tiene como ecuación ordinaria (x+1)² + (y+9)²=49
Responder:
1) x² + y²-8x + 10y + 16 = 0
2) x² + y² + x + 18y + 33 = 0
Explicación paso a paso:
A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;
x² + y² + 2gx + 2fy + c = 0 donde;
(-g, -f) es el centro.
1) Para la ecuación (x-4) ² + (y + 5) ² = 25
Expande el paréntesis;
(x-4) ² + (y + 5) ² = 25
x²-8x + 16 + y² + 10x + 25 = 25
x²-8x + 16 + y² + 10y + 25-25 = 0
Recopile términos similares;
x² + y²-8x + 10y + 16 + 0 = 0
x² + y²-8x + 10y + 16 = 0
Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0
2) Para la expresión (x + 1) ² + (y + 9) ² = 49
x² + x + 1 + y² + 18y + 81 = 49
x² + x + 1 + y² + 18y + 81-49 = 0
Recopile términos similares;
x² + y² + x + 18y + 82-49 = 0
x² + y² + x + 18y + 33 = 0
Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0

Find the measure of QS.
S9T 10 R 21 F 4x+5 Q
A. 35 B, 20 C. 27 D. 29
Answer:
C. 27
Step-by-step explanation:
((4x + 5) + 10)*10 = (21 + 9)*9 (two secants intersecting)
(4x + 5 + 10)*10 = (30)*9
(4x + 15)*10 = 270
40x + 150 = 270
40x = 270 - 150 (subtraction property of equality)
40x = 120
Divide both sides by 40
40x/40 = 120/40
x = 3
✔️QS = (4x + 5) + 10
Plug in the value of x
QS = 4(3) + 5 + 10
QS = 12 + 5 + 10
QS = 27

Isaac works as a cook at a restaurant. He started this week with 800 potatoes. On Monday, he used 380 potatoes. On Tuesday, he used 270 potatoes. How many potatoes were left at the end of Tuesday?
Answer:
The number of Potatoes remaining is = 150
Step-by-step explanation:
From the information given above,
On first day of the week (Sunday),
Total potato = 800
The number used include:
Monday = 380
Tuesday = 270
Total potato used = Monday + Tuesday
= 380 + 270 = 650
Remaining Potato = 800 - 650 = 150
Find the area of the regular polygon. Round to the nearest tenth.
Answer:
A polygon is a very big catagory. For example, a triangle has three sides, while a quadrilateral has four sides.
A triangle would be, A=h*w/2 (h being hight, and w being width)
A quadrilateral would be, A=h*w
Find the x-intercept and the y-intercept of the line 2x-5y= -6
Answer:
Step-by-step explanation:
2x - 5y = 6
5y = 2x - 6
y = 2/5x - 6/5
y-intercept is -6/5
x-intercept is when you say that y = 0
and so 6/5 = 2/5x
x = 6/2 = 3

PLEASE! 10 POINTS! For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?
Answer:
3Ax-6x = 15
3x(A-2)=15
If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2
x/5 - g = a for x
how can i find x?
Answer:
X = 5a+5g
Step-by-step explanation:
Adding g on both sides gives:
X/5 = a+g
Now dividing 5 on both sides gives us the value of x which is:
X = 5(a+g)
Hence X=5(a+g) or X=5a+5g( multiplying by 5 gives us 5a and 5g)
Which expression is equivalent to 2^2divided by 2/2^4
Answer: 32
Step-by-step explanation:
The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:
= 2^2 ÷ 2/2^4
= 4 ÷ 2/16
= 4 ÷ 1/8
= 4 × 8
= 32
The expression would be equal to 32 based on the above calculation

If (x-2,6)=(4,y+2)then the value of x=_____and y=____
x=6 , y = 4
Step-by-step explanation:
( x-2,6)=(4,Y+2)
this means; (x-2) &( 4) stands for" x "axis.
and( 6 )& (y+2) stands for y axis.
So, we can say( x-2)=X1 & (4)=X2 , (6)=Y1 & (y+2)=Y2
then; to Solve The Equation we use The Formula: X1=X2 for "X" And Y1=Y2 for "Y".
Solution: for "X" ; X1=X2
x-2= 4
x=4+2
x=6
For "Y" ; Y1=Y2
6 = y+2
y=6-2
y=4
finally check ; ( (x-2),6) = (4,(y+2) )
(6-2),6 = (4,(4+2) )
( (4),6) = (4,(6) )
(4,6) = (4,6)
so, X1 =X2 ; 4 = 4
Y1 = Y2 ; 6 = 6
Solve the following system of equations:
-2x + y = 1
-4x + y = -1
A: (3, 1)
B: (-1, 3)
C: (-1, -3)
D: (1, 3)
Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1

The distance between two stars is 9.0 x 10 to the power of -3 light years. A light year is equal to
5.88 x 10 to the power of 12 miles. What is the distance, in miles, between the two stars
Answer:
The distance between the two stars in miles is 5.292 * 10^10 miles
Step-by-step explanation:
Here, we want to make a conversion from light year to miles
To make this conversion, we simply are going to multiply the light year by the miles
Mathematically, we have this as;
9 * 10^-3 * 5.88 * 10^12
= 52.92 * 10^9
= 5.292 * 10^10 miles
