Answer:
2,740,754.11467 or 2,740,754
Step-by-step explanation:
800,000(1.08)^16
y=a(b)^x
a is the starting point
b is growth
x is years
you get the growth by adding 8 to 100 then dividing by 100.

Which of the following interpretations for the given expression is correct?
(5 y2 – 7)3
(2y)
Answer:
B
Step-by-step explanation:
the cube (this is the ³ at the end of the numerator) of
the difference of 5 times the square of y and 7 :
(5y² - 7)
all divided by the square (that is the ² at the end of the denominator) of
2 times y :
(2y)
A would be
((5y)² - 7)³/(2y)²
C would be
(((5y)²)³ - 7)/(2y²)
D would be
(5y² - 7)³/(2y²)
The girls varsity basketball team had 850 fans attend their first game of the season. For the second game they had 1037 fans attendance. What was the percentage increase in attendance?
Answer:
22%
Step-by-step explanation:
It's 22% because if we want to find the percent change in something, the formula for that is new number - (minus) old number, than divide by old number, and lastly multiply by 100. So,
1. 1037 - 850 = 187
2. 187 / 850 = 0.22
3. 0.22 x 100 = 22 --> 22%
Luigi's Pizzeria is having a Pi Day lunch special where you can choose either one 18" pizza or two 12" pizzas. The cost of each option is the same, $14.00. Which option gets you more pizza? Note: Pizza is measured by the diameter so a 10" pizza is 10" in diameter.
The option which gets you more pizza is two 12" pizzas.
What is a Diameter?It can be defined as the longest chord of the circle and it is twice the size of a radius.
We were told that one 18" pizza or two 12" pizzas costs the same and the one with the largest size is two 12" pizzas which was why it was chosen as the most appropriate choice.

on algebra, to move something to the other side of the equal sign you must make the variable cancel out.
so, in this case, we will add 2x to cancel out the -2x. after that rules of algebra state whatever we do to one side of the equal sign, we must do to the other. so we get 2x on the left side, resulting in 2x+y=-3

A town had a population of 10,000 people. the population decreased 3% each year. what was the population 5 years later?
Answer:
8,588 people
Step-by-step explanation:
We can represent this exponential decay as [tex]P=10000(0.97)^n[/tex] where [tex]n[/tex] is the number of years later:
[tex]P=10000(0.97)^n\\\\P=10000(0.97)^5\\\\P=10000(0.8587340257)\\\\P=8587.340257\\\\P\approx8588[/tex]
Therefore, the population 5 years later will be 8,588 people
Step-by-step explanation:
Ok so after the first year we expect the population to reach 97% of it's initial population.
So 97% of 10 000 can be written as:
97/100 ×10 000=0.97×10 000=9 700
After the second year we expect the population to drop to 97% of the first year's population
So, it can be said that:
0.97×9700= 9409
Similarly after year 3,
0.97× 9409= 9126.73
Year 4,
0.97× 9126.72= 8852.9281
Year 5,
0.97× 8852.9281=8587 rounded to the nearest number
The new population would be 8587

If 12 inches = 1 foot, how many inches are in 8 feet?
Answer:
96 inches
Step-by-step explanation:
Given the following question:
12 inches = 1 foot
To find the answer we simply need to multiply 12 by 8, since every 12 inches are equal to 1 foot and we need to find how many inches are in 8 feet.
[tex]12in=1ft[/tex]
[tex]8\times12=96[/tex]
[tex]=96in[/tex]
8 feet is equal to "96 inches."

A family took a road trip and traveled west a distance of 350 kilometers in 7 hours. What was their velocity during this
Answer:
50 km/h
Step-by-step explanation:
so you traveled total of 350 (km) in 7 (hours) right?, just take 350, divide it by 7, which will give you km/h. (or 50 km/h) and then when you add a direction it like "west" it's no longer a speed it's a velocity.
Displacement given (in metres) = (350 × 1000)m.
Displacement = 350000 metres.
Time = (7× 3600) seconds
Time = 25200 seconds.
Velocity = Displacement / Time
Velocity = 350000 / 25200
Velocity = 13.89m/s
Approximately, Velocity = 14m/s.
What is the average

a rectangle has a length 12 meters and a width of 400 centimeters. what is the perimeter, in cm of the rectangle
Answer:
P= 3200 cm
Step-by-step explanation:
Perimeter = 2(l+w)
In this case since the perimeter has to be in centimeters, we have to change the length of the rectangle to centimeter.
12 meter to centimer = 12 x 100 = 1200 cm
2( 1200 +400)
2 (1600)
= 3200 cm

I will start off by defining the angle
[tex] \alpha = 90 - \beta [/tex]
as being the angle between altitude and the hypotenuse of the triangle.
[tex] \alpha = 90 - 30.1 = 59.9[/tex]
Using trigonometry, and the definition of the tan function defined by
[tex] \tan( \alpha ) = \frac{opp}{adj} = \frac{x}{1836.3} [/tex]
[tex] \tan( 59.9 ) = \frac{x}{1836.3} [/tex]
[tex]x = 1836.3 \times \tan(59.9) [/tex]

You can find the derivative of the inverse function by differentiating the inverse explicitly, or by using the formula:
If a function f(x) has an inverse f ⁻¹(x), then by definition
[tex]f\left(f^{-1}(x)\right) = x[/tex]
Differentiating both sides with respect to x yields
[tex]f'\left(f^{-1}(x)\right) \times \left(f^{-1}\right)'(x) = 1 \implies \left(f^{-1}\right)'(x) = \dfrac1{f'\left(f^{-1}(x)\right)}[/tex]
Now, if f(a) = b and b = f ⁻¹(a), then
[tex]\left(f^{-1}\right)'(a) = \dfrac1{f'\left(f^{-1}(a)\right)} = \dfrac1{f'(b)}[/tex]

Answer:
P (A|C) = 0.39
P (C|A) = 0.446
Step-by-step explanation:
The data provided is as follows:
Blood Group
O A B AB Total
1) 0.082 0.101 0.005 0.004 0.192
Ethnic Group 2) 0.140 0.141 0.018 0.009 0.578
3) 0.215 0.195 0.070 0.020 0.500
Total 0.437 0.437 0.093 0.033
The event C = {Ethnic group 3 is selected}
Compute the value of P (A|C) as follows:
[tex]P(A|C)=\frac{P(A\cap C)}{P(C)}=\frac{0.195}{0.5}=0.39[/tex]
If we know that the individual came from ethnic group 3, the probability that he has type A is given by P(A | C) = 0.39.
Compute the value of P (C|A) as follows:
[tex]P(C|A)=\frac{P(A\cap C)}{P(A)}=\frac{0.195}{0.437}=0.446[/tex]
If we know that the individual has type A blood group, the probability that he came from ethnic group 3 is given by P(C | A) = 0.446.
