Answer:
A 104,689
Step-by-step explanation:
y= a x b^x
y=50,000 x 1.03^x
The population after 25 years is 104689.
The correct option is A.
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
Given:
The population of a city is, 50000,
and growing 3% each year.
That means, the function that represents the situation is,
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and sx is the time period.
So,
y = 50000(1+0.03)²⁵
y = 104688.89
y ≈ 104689
Therefore, the population is, 104689.

Find the distance between Point A(9, 10) and B(-1,9) to the nearest tenth.
Answer:
10.0
Step-by-step explanation:
see attached for reference.
given two points in the x-y axis (x₁, y₁) and (x₂, y₂)
the distance bettween them is given by
Distance, D = √ ( (x₂-x₁)² + (y₂-y₁)² )
In our case we are given points (9,10) and (-1,9)
substituting these into the formula , we get:
D = √ ( (9-10)² + (-1-9)² )
= √ ( (-1)² + (-10)² )
= √ ( 1 + 100 )
=√101
= 10.04988
= 10.0 (rounded to nearest tenth)

HELP ME PLEASE!!! A Kite flying in the air has a 12 feet line attached to it. It's line is pulled and cast an 11 feet shadow. Find the height of the kite. If necessary round your answer to the nearest 10th
Step-by-step explanation:
By Pythagoras' theorem,
12^2 = 11^2 + height^2
height = ±√12^2 - 11^2 (rej -ve value since height > 0)
height = 16.279 (5sf) = 16.3 (nearest tenth place)

The total charge in dollars for a car rental can be determined by using the function c = 0.4x + 35, where c represents the total cost of the rental and x represents the total distance traveled in miles. Which statement justifies that the total cost for renting this car and driving a distance of 100 miles is $75.00? The total cost increases $0.40 for every 35 miles traveled. The total cost increases $35.00 for every 40 miles traveled. There is an initial charge of $35.00 for every mile traveled. The cost increases $0.40 for every mile traveled after an initial charge of $35.00.
Answer:
There is an initial charge of $35.00 for every mile traveled.
Step-by-step explanation:
From the question, the cost function s given as follows:
c = 0.4x + 35 .................... (1)
Where;
Total cost = c
Variable cost per mile = $0.40
Number of miles traveled = x
Total variable cost = 0.4x = 0.40 * x
Fixed cost = Initial cost = $35
From the above, the fixed cost or initial cost implies that no matter the number of miles a passenger takes, he is going to pay $35 in addition to the variable cost to pay.
From the question, for driving a distance of 100 miles we have:
Number of miles traveled = x = 100
Total variable cost = 0.40 * 100 = 40
Substituting the relevant value into equation (1), we have:
c = 40 + 35
c = 75
Since the total cost obtained above is $75.00, it therefore implies that the correct statement that justifies that the total cost for renting this car and driving a distance of 100 miles is $75.00 is "There is an initial charge of $35.00 for every mile traveled".

"What is the A.P.R. after the introductory period ?" you find before thinking about signing up.
An introductory APR seems to be a special rate of interest offered by credit card providers to prospective clients for something like a predetermined period of months following opening a bank account.Numerous credit cards provide promotional APRs upon expenditures buying products, debt transfers, or sometimes both. Such rate was considerably cheaper than the estimated APR, typically as minimal as 0%.

Which transformation carries the trapezoid onto itself?
A. a reflection across the line y = 0
B. a rotation of 180° about the point (- 1, 0)
C. a rotation of 180 ° about the origin
D. a reflection across the line x = - 1 -1
Answer: D. a reflection across the line x = - 1
Step-by-step explanation:
First, you can see that the lengths of the top and the base of the figure are different, so we can discard the rotations of 180°, because those will give a different figure.
Now, for reflections, we need to reflect the image around a line of symmetry.
A line of symmetry means that the image at the right of the figure is an exact reflex of the image at the left of the figure, for this particular case, we can find a line x = c. Such that the distance between c and the x-component of the top vertexes is the same for both of them.
(Again, because the top and the bottom have different lengths, there is no line y = b such that a reflection across that line will leave the figure invariant)
The left top vertex is at x = -3
The right top vertex is at x = 1.
We can find the mid-value between them as:
c = (-3 - 1)/2 = -2/2 = -1
Then:
-3 - c = -3 - (-1) = -3 + 1 = -2
1 - c = 1 - (-1) = 2
While the numbers are different (in sign) as those represent distance between points, we only care for the absolute value, in that case:
I-2I = I2I
Then the distances are exactly the same, and we can take c = -1
This means that a reflection about the line x = -1 carries the figure onto itself.
Then the correct option is:
D. a reflection across the line x = - 1

these bugs are not drawn up to scale what does that mean
It means that they do not have the proper proportions that they normally would in real life. The drawing might be larger or smaller than the bugs but even then it might have the proper proportions, it is only when it has incorrect proportion sizes, that is is considered "not to scale"
I hope this helps :)
Answer:
That means if you measure the bugs from the chart/paper/assignment, the real bugs aren't that size.

The length of a jogging trail is 3528 m. A jogger wants to complete the trail within 30 min. How many meters must the jogger travel each minute?
Step-by-step explanation:
We have to find the distance the jogger must travel each minute. The distance covered in one minute is:
d= 3528/1800= 1.96 m
Therefore, the distance covered in one minute, or 60 seconds is:
dt= 1.96 × 60 = 117.6 m
The solution needed is, dt=588/5 = 117 (3/5) m

(7 points) Cars arrive at a toll both according to a Poisson process with mean 80 cars per hour. If the attendant makes a two-minute phone call, what is the probability that at least 1 car arrives during the call
Answer:
The probability that at least 1 car arrives during the call is 0.9306
Step-by-step explanation:
Cars arriving according to Poisson process - 80 Cars per hour
If the attendant makes a 2 minute phone call, then effective λ = 80/60 * 2 = 2.66666667 = 2.67 X ≅ Poisson (λ = 2.67)
Now, we find the probability: P(X≥1)
P(X≥1) = 1 - p(x < 1)
P(X≥1) = 1 - p(x=0)
P(X≥1) = 1 - [ (e^-λ) * λ^0] / 0!
P(X≥1) = 1 - e^-2.67
P(X≥1) = 1 - 0.06945
P(X≥1) = 0.93055
P(X≥1) = 0.9306
Thus, the probability that at least 1 car arrives during the call is 0.9306.

A line intersects the points (0,-4) and (1,2). What is the slope-intercept equation for this line
Answer:
y = -2x
Step-by-step explanation:
First you can find the difference between the two points to find the slope.
0, 4
- 1, 2
-1, 2
Now divide: y/x = 2/-1 = -2
Slope = -2
Formula: y=mx+b
Plug in the points for the variables.
2 = -2(1) + b
2 = -2 + b
Subtract 2 from both sides to get 0 = b so this line is proportional.
