The value of a particular investment follows a pattern of exponential growth. In the year 2000, you invested money in a money market account. The value of your investment t years after 2000 is given by the exponential growth model A=1700e^0.062t When will the account be worth $2466?
Answer:
The value of the investment will be worth $2466 in the year 2017
Step-by-step explanation:
In this question, we are tasked with finding the specific year in which an amount invested in a money market account reaches a particular value
To get this year, what we need to do is to get the value of t from the exponential equation given in the question. To get t, we simply make the value of A set to the particular value in the question.
Hence, we use [tex]A = 1700e^{0.062t} \\[/tex]
Now, we plug the value of A = 2466 and take the natural logarithm of both sides i.e [tex]Log_{e}[/tex] or simply ln
From;
[tex]2466 = 1700e^{0.062t}[/tex]
ln 2466 = ln[tex]1700e^{0.062t}[/tex]
ln 2466 = 0.062t ln1700
7.81 = 0.062t × 7.44
t = 7.81/(0.062 × 7.44)
t = 16.93 approximately 17 years
This means that the value of the investment will have that worth in the year 2000+17 = year 2017
What is the length of the missing leg?
15 m/
9 m
meters
Answer:
The length of the missing leg is approximately 17.49 meters.
Explanation:
To find the length of the missing leg in a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, if one leg(hypotenuse) is 15 meters and the other leg(base) is 9 meters, and we denote the missing leg as [tex]\(x\)[/tex] meters, we have:
[tex]\[x^2 + 9^2 = 15^2\][/tex]
[tex]\[x^2 + 81 = 225\][/tex]
[tex]\[x^2 =144 \][/tex]
Now, to find [tex]\(x\)[/tex] , we take the square root of both sides:
[tex]\[x = \sqrt{144}\][/tex]
[tex]\[x = 12\][/tex]
Question:
A right triangle's leg is 9 and the hypotenuse is 15, what is the other leg s length?

The roof of the house down the road is in the shape of a square pyramid. The length from the gutter to the top is ퟏퟓ풇풕.and the length of gutter on one side is ퟏퟖ풇풕.with no overlap. One bundle of shingles covers ퟐퟓsquare feet. How many bundles should you buy to cover
Answer:
Therefore, the number of bundles to be bought is 22 bundles
Step-by-step explanation:
Here we have;
Dimensions of roof
Square pyramid = 4 triangular sides
Base length of triangle = Length of gutter on one side = 18 ft
Height of triangle = Length from the gutter on one side to the top of the roof = 15 ft
∴ Area of one of the four triangles = 0.5 × Base × Height = 0.5 × 15 × 18 = 135 ft²
Total area of four sides of the pyramid = 4 × Area of one of the four triangles
∴ Total area of four sides of the pyramid = 4 × 135 ft² = 540 ft²
Area covered by one bundle of shingle = 25 ft²/bundle
Therefore number of bundles of shingles required = [tex]\frac{Total \, area \ of \, four \ sides \ of \ the \ pyramid}{Area \ covered \ by \ one \ bundle \ of \ shingle} = \frac{540 \ ft^2}{25 \ ft^2/bundle} = 21.6 \ bundles \approx 22 \ bundles[/tex]
Therefore, the number of bundles to be bought = 22 bundles.
Yol drove 390.25 miles back home to surprise his brother for his birthday. The drive took 7 hours. What was Yol's average speed for the trip, in miles per hour?
Answer:
55.75 miles/hour is the average speed
Step-by-step explanation:
In this question, we are asked to calculate the average speed attained by Yol if he traveled a certain distance within a given time frame.
To calculate his average speed, what we do is to divide the distance travelled by Yol by the number of hours he traveled.
mathematically what we are saying is that
Average speed = Total distance/ Total time
From the question, the distance is 390.25 miles while the time is 7 hours
we now input these values
Average speed = 390.25/7 = 55.75 miles per hour is the average speed

The measure of the diving angle is 14°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,

Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning.
If interest rates stay at 4% APR and I continue to make my monthly $50 deposits into my retirement plan, I should have at least $30 comma 000 saved when I retire in 25 years.
The statement ___________ because I will have $ ___________ nothing in my retirement account when I retire in 25 years.
(Round to the nearest cent as needed.)
Answer:
False
$25,706.48
Step-by-step explanation:
The annual percentage rate (APR) is 4%, so the monthly rate is 4%/12 = ⅓%.
25 years = 300 months.
The monthly deposit (annuity) is $50.
The future value of the annuities is:
F = A [(1 + i)ⁿ − 1] / i
Given i = 1/300, A = 50, and n = 300:
F = 50 [(1 + 1/300)³⁰⁰ − 1] / (1/300)
F = 25,706.48
The statement is false. The amount after 25 years is less than $30,000.
The statement doesn't make sense because if you make $50 monthly deposits at a 4% APR for 25 years, you will have approximately $41,981.86 in your retirement account, not only $30,000.
Explanation:The statement does not make sense or is clearly false. Let's add up the total deposits over 25 years and calculate the interest gained using the given annual percentage rate (APR) of 4%.
Total deposits = $50/month * 12 months/year * 25 years = $15,000Using formula for compound interest, Final Value = P (1 + r/n)^(nt) where P is principal amount (initial investment), r is annual interest rate (decimal), n is number of times that interest applied per time period, t is time the money is invested for. In this case, P=$50, r=4%/12/100%=0.003333, n=1 (monthly), t=12*25=300. After calculations, the final value comes to approximately $41,981.86Therefore, if you continue to make $50 monthly deposits with a 4% APR for 25 years, you will have just under $41,981.86 in your retirement account, not $30,000 as stated. So, the statement is inaccurate.

The radius is 3.9 units
What is radius of circle?In geometry, the radius is defined as a line segment joining the center of the circle or a sphere to its circumference or boundary. It is an important part of circles and spheres which is generally abbreviated as 'r'. The plural of radius is "radii" which is used when we talk about more than one radius at a time. The largest line segment in a circle or sphere joining any points lying on the opposite side of the center is the diameter, and the length of the radius is half of the length of the diameter. It can be expressed as d/2, where 'd' is the diameter of the circle or sphere. Look at the image of a circle given below showing the relationship between radius and diameter.
given:
As, CB ⊥ AC by the radius-tangent theorem.
In ΔABC, applying the Pythagoras theorem
r² + 8² = (r+ 5)²
r² + 64= r² + 25 + 10 r
64 - 25 = 10 r
39 = 10r
r= 39/10
r= 3.9 units

Chef Selena is making her special dish that requires pasta, sauce, and onions.
She has 5 1/8 pounds of pasta, 6 pounds of sauce, and 47/8 pounds of onions.
How many servings of her dish can she make if each serving is 12 pounds?
Which two equations are needed to solve the problem?
Answer:
4/3 servings or her dish can be made
These are the 2 equations:
Total = 5 and 1/8 pounds + 6 pounds + 4 and 7/8 pounds
N = Total / 10
Step-by-step explanation:
We know 1 serving = 12 pounds
We want the number of servings able to make. call it N
N = (Total pounds)/ (12 pounds/serving)
P = pasta per serving
S = sauce per serving
O= onions per serving
It appears that
P*N = 5 and 1/8 pounds
S*N = 6 pounds
O*N = 4 and 7/8 pounds
5 and 1/8 + 6 + 4 and 7/8 = Total
16 pounds total.
N = 16/12 = 4/3 servings
Total = 5 and 1/8 pounds + 6 pounds + 4 and 7/8 pounds
N = Total / 10

Johnny is trying to figure out how many miles he rode on his bike today.
He knows his bike uses wheels that are 30" tall, and it takes him 1 second
for it to make one complete revolution. If he rode for 1 hour and 11
minutes, how many miles did he ride? Use 3.14 for pi and round your
answer to the nearest mile.(Please note that 60 seconds = 1 minute, 60
minutes = 1 hour, 12" = 1 ft, and 5,280 ft = 1 mile).
PLEASE HELP !
Answer:
6 miles
Step-by-step explanation:
The time Johnny rode was ...
1 h 11 min = (60 min) +(11 min) = 71 min = 71 × (60 sec) = 4260 sec
The distance of one revolution of the bike tire is ...
C = πd = 3.14(30 in) = 94.2 in
So, the total distance Johnny rode was ...
(4260 sec)×(94.2 in/sec) = 401,292 in
__
We know there are 5280 feet in a mile, and each of those is 12 inches. So, the number of inches in a mile is ...
5280 ft = 5280×(12 in) = 63,360 in
__
The number of miles Johnny rode can be found by dividing the total distance by the distance in 1 mile:
(401,292 in)/(63,360 in/mile) = 6.33 mile
Johnny rode about 6 miles in 1 hour 11 minutes.
