Answer:
$14400
Step-by-step explanation:
Given data
Principal= 6000
Time= 14 years
Rate= 10%
Let us use the simple interest expression to find the final amount
A=P(1+rt)
substitute
A=6000(1+0.1*14)
A=6000(1+1.4)
A=6000*2.4
A=$14400
Hence based on a simple interest model the final amount is $14400

A) linear and increasing
B) Non linear and decreasing
C) linear and decreasing
D) Non linear and increasing
Answer:
D) non-linear and increasing
Step-by-step explanation:
The points do not go up into a straight line with equal or even points. However, it is increasing or going up as you can see on the graph.
Hope this helps, good luck! :D
Answer:
A) linear and increasing
Step-by-step explanation:
the line between x = -4 and x = -1 is a straight line, thus, it's a linear, and it's also increasing
Rewrite the function f(x)=2(x-2)^2+6 in the form f(x)=ax^2+bx+c.
Answer:
To write a polynomial in standard form, simplify and then arrange the terms in descending order.
f(x)=ax²+bx+c
Simplify each term.
f(x)=2x²−8x+8+6
Add 8 and 6.
f(x)=2x²−8x+14

Khan Academy Question :)
9514 1404 393
Answer:
40 units
Step-by-step explanation:
The slanted side is the hypotenuse of a triangle that is 8 units high and 6 units wide. Its length can be found from the Pythagorean theorem:
d² = 6² + 8² = 100
d = √100 = 10
The perimeter is the sum of side lengths. Those lengths can be found by counting grid squares. Clockwise from the upper left corner, the sum of side lengths is ...
P = 8 + 10 + 14 + 8
P = 40 . . . units

sale committee wants to raise $186 for a donation to a local charity they set a size $12 of their profit at the end of each day how many days will it take them to raise enough money for the whole donation
Answer:
15 and a half days
Step-by-step explanation:
Since they earn $12's each day you would do $186 divided by $12 which would be 15.5 so it would take them 15 and a half days to raise $186.
Answer:
Sorry if this is late, but I hope you understand now.
Step-by-step explanation:
It's 16 days actually, if you divide 186 divided by 12, it's 15.5 we can say, that 5 should be rounded up or down. 15.5 is a fraction of 15/5 so if we rounded it, it would be 16. That's our newer version of rounding. 5 is higher, 4 is lower. Use that to help you :) I hope you understand even though it late
Given that f(x) = x2 - 5x+6, evaluate the function f(6).
Answer:
f(6) = 12
Step-by-step explanation:
We are given the following function:
[tex]f(x) = x^2 - 5x + 6[/tex]
Evaluate the function f(6).
This is [tex]f(x)[/tex] when [tex]x = 6[/tex]. So
[tex]f(6) = 6^2 - 5(6) + 6 = 36 - 30 + 6 = 12[/tex]
f(6) = 12 is the answer.
If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
Answer:
The future value is $3793.776
Step-by-step explanation:
Given
[tex]PV = 2940[/tex] --- present value
[tex]r = 3.2\%[/tex] --- rate
[tex]t = 8[/tex] --- time
[tex]n = 4[/tex] --- quarterly
Required
Determine the future value
This is calculated using:
[tex]FV = PV(1 + \frac{r}{n})^{nt[/tex]
So, we have:
[tex]FV =2940 * (1 + \frac{3.2\%}{4})^{4*8[/tex]
[tex]FV =2940 * (1 + \frac{3.2}{400})^{32[/tex]
[tex]FV =2940 * (1 + 0.008)^{32[/tex]
[tex]FV =2940 * (1.008)^{32[/tex]
[tex]FV =2940 * 1.2904[/tex]
[tex]FV =3793.776[/tex]

9 (t + 19) = 7t + 17
What value of t makes the equation true?
Answer:
9t + 171 = 7t + 17
9t - 7t =17 - 171
2t/2 = -154/2
t = -77

Explain how you would solve −4 + 4 + 5. Please help me lol.
Answer:
5
Step-by-step explanation:
=> -4+9
=> 5
Cuz first u have to do 4 plus 5, which'll be 9. And then, since -4 is negative, we have to subtract 9 from 4. So the answer's 5.
Make me brainliest :))))
Suppose that a hospital administrator states that the average weight at birth of all boys born at the certain hospital is 7 pounds. If the data you have shows, with 95% certainty, the average weight at birth of all boys born at that hospital is between 6.6 and 7.2 pounds. Do you agree with the administrator with 95% confidence
Answer:
Yes
Step-by-step explanation:
Here,
The average weight at birth of all boys born at a certain hospital is 7 pounds.
and [tex]95\%[/tex] confidence interval for the mean,
The average weight at birth of all boys born at that hospital is between [tex]6.6[/tex] and [tex]7.2[/tex] pounds.
[tex](6.6,7.2)[/tex]
Yes, We agree with the administrator with the [tex]95\%[/tex] confidence as [tex]7[/tex] lie in the interval.

Aaron was offered a job that paid a salary of \$57,000$57,000 in its first year. The salary was set to increase by 1% per year every year. If Aaron worked at the job for 29 years, what was the total amount of money earned over the 29 years, to the nearest whole number?
Answer:
The total amount received is: $1906650
Step-by-step explanation:
Given
[tex]a = \$57000[/tex] --- initial
[tex]b = 1\%[/tex] --- rate
[tex]n = 29[/tex] --- time
Required
Determine the total amount at the end of 29 years
The given question is an illustration of geometric progression, and we are to solve for the sum of the first n terms
Where [tex]n = 29[/tex]
[tex]r = 1 + b[/tex]
[tex]r = 1 + 1\%[/tex]
Express percentage as decimal
[tex]r = 1 + 0.01[/tex]
[tex]r = 1.01[/tex]
The required is the calculated using:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
So, we have:
[tex]S_n = \frac{57000 * (1.01^{29} - 1)}{1.01 - 1}[/tex]
[tex]S_n = \frac{57000 * (1.3345- 1)}{0.01}[/tex]
[tex]S_n = \frac{57000 * 0.3345}{0.01}[/tex]
[tex]S_n = \frac{19066.5}{0.01}[/tex]
[tex]S_n = 1906650[/tex]
The total amount received is: $1906650
Grumpy Corp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines drug users 96% of the time(a Positive test) and correctly determines non-users 90% of the time(a Negative test). A recent study concluded that 36% of college students use drugs. A potential employee has been tested and the result was Negative for drug use.
Required:
a. Construct ALL necessary probabilities using proper notation(Example: P(D) for a "drug user").
b. Find the Probability of a Negative test, by showing use of the above Probabilities first, and then followed by the proper calculation.
Answer:
Hence, the probability of a Negative test is [tex]P(T^C)=0.5904[/tex].
Step-by-step explanation:
(a)
Let [tex]D=[/tex] Drug user and [tex]T=[/tex] Test positive
Probability of drug users [tex]P(D)=36\%=0.36[/tex]
[tex]P(\frac{T}{D})=96\%=0.96[/tex]
[tex]P(\frac{T^c}{D^c})=90\%=0.90[/tex]
(b)
Find the Probability of a Negative test,
[tex]P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)[/tex]
[tex]\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36[/tex]
[tex]\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36[/tex]
[tex]\Rightarrow P(T^C)=0.576+0.0144[/tex]
[tex]\Rightarrow P(T^C)=0.5904[/tex]

Answer:
x=4
Step-by-step explanation:
x=4
Step-by-step explanation:
first subtract 4 from both sides of the equation 2x+4-4=12-4
simplify 2x=8
divide both sides of the equation by the same term
2x=8
2 2
cancel the terms that are in the numerator and denominator then decide the numbers
x=4
Sequences:
See the following attached image, where you can see sets of circles, which follow a certain pattern:
Number of circles in next row 6: 21 circles, and row 7: 28 circles
1) Determine the number of circles in the nth pile (general term)
2) What is the number of circles when n tends to infinity?
Answer:
The sequence is
1, 1 + 2, 1 + 2 + 3, 1 + 2 + 3 + 4, ...Each term is the sum of the consecutive numbers from 1 to that number.
The nth term is the sum of the first n numbers:
aₙ = 1 + 2 + 3 + ... + naₙ = 1/2n(1 + n) (formula for sum of the n terms of arithmetic progression with the first term of 1 and common difference of 1)aₙ = n(n + 1)/21) The number of circles in the nth pile is n(n + 1)/2
2) When n tends to infinity the number of circles tends to infinity
