Which of the following functions would give the population Plt) as a function
of t, in years, given that the initial population is 2,500 and that the population
is growing at an annual rate of 4%?
(1) P(t)=2500(0.96)
(3) P(t)=2,500(1.04)
(2) P(t)=(1.04) +2,500
(4) P(t)= 1.04t +2,500
Answers
Answer:
[tex]P(t)=2500(1.04)^t[/tex]
Step-by-step explanation:
None of your proposed answers has an exponent t.
Here's the logic behind the answer:
Year 0: pop. = 2500
Year 1: pop. = 2500(1.04) That is 104% of the previous year's pop.
Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2
Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3
See the pattern? The exponent matches the year number.

Find the surface area of the square pyramid, Show your work please : )
Answers
Answer:
105in²
Step-by-step explanation:
Surface area is the total area of the faces.
The faces of pyramid consist of triangles and a square
The area of a square can easily be calculated by squaring the side length
the square of this pyramid has a side length of 5
so
area of square = 5²
5² = 25
the area of the square is 25in²
Now to find the area of the triangles
All we have to do is find the area of one triangle and multiply that buy 4 ( because there are four triangle)
the area of a triangle can be calculated using this formula :
[tex]A=\frac{bh}{2}[/tex] where b = base and h = height
The triangles have a base length of 5 in and a height of 8 in
so
[tex]A=\frac{5*8}{2} \\5*8=40\\\frac{40}{2} =20\\A=20[/tex]
So the area of one triangle is 20 in²
Now we multiply 20 by 4 to find the area of all 4 triangles
20 * 4 = 80
So the total area of the triangles is 80in²
Finally we add the two areas together
Surface area = 80 + 25
80 + 25 = 105
Hence, the surface area is 105in²
Answer:
105 in.
Step-by-step explanation:
To find the area of a square pyramid, use this formula
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height.
The base is a square.
To find the area of a square, simply multiply the side length by itself twice (x^2).
5 x 5 = 25.
25 is the area of the base.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ p ⋅ height.
To find the perimeter of a square, add every side length; the sum is the perimeter.
5 + 5 + 5 + 5 = 20.
20 is the perimeter of the square.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ 20 ⋅ height
The height is the number along the little lines.
8 is the height.
Now that we have all parts of the formula, we have our final equation.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ 20 ⋅ 8 = 105.
105 in. is the surface area of the square pyramid.

Completely simplify the rational expression LaTeX: \frac{7x}{3y} + \frac{12x}{9y}
Answers
Answer:
[tex]\frac{11x}{3y}[/tex]
Step-by-step explanation:
[tex]\frac{7x}{3y} + \frac{12x}{9y}[/tex]
To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.
The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.
[tex]\frac{7x}{3y}\cdot\frac{3}{3}+\frac{21x}{9y}=\frac{21x}{9y}+\frac{12x}{9y}\\=\frac{21x+12x}{9y}\\=\frac{33x}{9y}[/tex]
Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.

Step-by-step explanation:
The most useful way to compare fractions is to add extra zeros at the end.
For example, 0.67 ___ 0.80.
0.80 is obviously bigger than 0.67.
In 24.4, 24.54, 24.304, 24.24, you can add extra zeros as well.
24.400, 24.540, 24.304, 24.240 (This makes it much easier to group the numbers, whether from largest to smallest or smallest to larger).

C. h(x) = 4(x-18)2 - 5
D. h(x) = 4(x - 5)2 - 18

To shift h units to the right, replace x with x - h
To shift h units to the left, replace x with x + h.
To shift k units up, add k to the end of the formula for the function.
To shift k units down, subtract k from the end of the formula.

Do the side lengths 9,12, and 17 form a right triangle?
Answers
Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 17 and 17² = 289
9² + 12² = 81 + 144 = 225 ≠ 289
Then the triangle is not right
