The graph of a quadratic function with vertex (-2,-4) is
Find the domain and the range.
Write the domain and range using interval notation.
Answer:
Domain: (-∞, ∞); Range: (-∞, -4]
Step-by-step explanation:
Domain is the set of all possible input values of a function (or on a graph, the leftmost and rightmost extensions of the function).
Since this is a parabola, the function will extend left and right for negative infinity and infinity respectively.
Range is the set of all possible output values of a function (or on a graph, the uppermost and lowermost extensions of the function).
While the function on this graph will extend downward for negative infinity, the uppermost limit is -4, as y (output) value of the vertex.

Paul and sandy Moede signed at 8,000 note at Citizen's bank. Citizen's charge a 61/2% discount rate. If the loan is for 300 days, find (a) the proceeds and (b) the effective rate charged by the bank to the nearest
The proceeds is $7,566.67 and the effective rate charged by the bank to the nearest is 6.87%.
How to find the effective interest rate?Given data:
Principal = $8,000
Rate =6 1/2% or 6.5%
Term= 300 Days
a. Proceeds
Interest = Principal x Rate x Time
Interest = $8,000 x 6.50% x 300/360
Interest = $8,000 x 0.065 x 0.8333
Interest = $433.33
Now let find the Proceeds:
Proceeds = $8,000 - 433.33
Proceeds = $7,566.67
b. Effective Interest Rate:
Effective Interest Rate = 433.33 / 7566.67 x 300/360
Effective Interest Rate = 433.33 / 6305.56
Effective Interest Rate = 0.0687 × 100
Effective Interest Rate = 6.87%
Therefore $7,566.67 is the proceeds and 6.87% is the interest rate.

In a certain distribution, the mean is 70 with a standard
deviation of 3. At least what fraction of the numbers are
between the following pair of numbers?
61 and 79
Answer:
8/9
Step-by-step explanation:
You want to know the least fraction of the distribution that lies between 61 and 79 if the mean is 70 and the standard deviation is 3.
Chebyshev's InequalityChebyshev's inequality tells you that at most 1/k² of the distribution will lie beyond k standard deviations from the mean.
ApplicationHere, the given limits are (61 -70)/3 = -3 and (79 -70)/3 = 3 standard deviations from the mean. That is, we can use k=3 to find the maximum fraction that is beyond the interval [61, 79]. That fraction is ...
1/k² = 1/3² = 1/9
Since this is the maximum fraction outside the given range, the minimum fraction inside the given range is ...
1 -1/9 = 8/9
At least 8/9 of the number are between 61 and 79.

(a) Decide whether the problem relates to an ordinary annuity or an annuity due.
o ordinary annuity
annuity due
(b) Solve the problem. (Round your answer to the nearest cent.)
$
The income that this settlement provide at the end of each month is: $813.20.
How to find the monthly payment?Monthly amount= $1.500,000 at the end of year 35 years.
Interest rate per month = 7.1/12 = 0.59167% per month
Total periodic cash flow = 35× 12 = 420
Hence,
Future value of annuity = X × [(1+ 0.0059167)^420 -1/ 0.0059167]
Future value of annuity =X × [(1.0059167)^420 -1/ 0.0059167]
Future value of annuity = X × [(1.0059167)^420 -1/ 0.0059167]
Future value of annuity = X × [11.913727 -1 / 0.0059167]
Future value of annuity = X × [10.913727 / 0.0059167]
Future value of annuity =X × 1,844.5633

You scored an 85 on a test. This corresponds to a z-score of 1.80. What percentage of the scores are better than yours?
At a z-score of 1.80, the percentage of the scores that are better than yours is equal to 3.59%.
What is a z-score?In Mathematics, a z-score is sometimes referred to as a z-value or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.
How to determine the percentage?Mathematically, the z-score of a given sample score in a normal distribution can be calculated by using this formula:
Z-score = (x - μ)/σ
Where:
x represents the sample score.σ represents the standard deviation.μ represents the mean score.Since a score of 85 on a test corresponds to a z-score of 1.80, the percentage of the scores that are better than yours is given by:
P(x > 85) = P(z > 1.80)
P(z > 1.80) = 0.0359
P(z > 1.80) = 3.59%.

nearest million.
The growth formula for the given population is P = 182eⁿˣ and the population in 2004 is 186.98 million
Growth function:
Basically, the growth function means the pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
Given,
A country's population in 1994 was 182 million. In 2002 it was 186 million.
Here we need to find the growth formula and the population in 2004.
According to the given problem, let us consider that the
final population P,
the starting population A, and
the time passed t.
Here we need to determine the value of the growth factor k.
And it can be calculated using the information for the years 1994 and 2002.
Here we know that, A will be 182 million (the population in 1994), P will be 186 million (the population in 2002), and t will be 8 years (the number of years between 1994 and 2002):
⇒186 = 182eⁿˣ⁸
⇒186/182 = e⁸ⁿ
Now, by applying ln to both sides of the equation:
⇒ln(186/182) = ln(e⁸ⁿ)
Using the laws of logarithms:
=> 8n = ln(186) - ln(182)
=> n = [ln(186) - ln(182)] / 8
=> n = 0.0027
Now, let's use this information to determine P in 2004.
Here the value of A will still be 182 million, but t will be 10 years.
Now, we have to apply these values then we get,
=> P = 182e⁰°⁰⁰²⁷ˣ¹⁰
=> P = 182e⁰°⁰²⁷
=> P = 182 x 1.0273
=> P = 186.98
Therefore, there are 186.98 million in 2004.

and you don't know how to do it ? what happened to you in elementary school ?
there are many different techniques. everybody thinks theirs is the fastest or easiest to understand.
after all, this is just "playing" with numbers, the factors embedded within the dividend.
this is mine. when I was in elementary school, we called this the "long division" :
62.79 ÷ 23 =
we pick the first few positions from the left of the dividend, where we are sure, the divisor fits at least once.
in our case here : 62.
we do an integer divide of 62/23 = 2 (for 3 the dividend would have to be at least 69). this 2 is our first digit of the quotient.
62.79 ÷ 23 = 2
now we multiply the divisor by that digit and subtract the result from the dividend. this gives us a remainder of 16, and we pull down the next position (7) :
62.79 ÷ 23 = 2
- 46
---------
167
now, we pulled the first digit after the decimal point, and we need to set the decimal point there in our quotient :
62.79 ÷ 23 = 2.
- 46
---------
167
now, we repeat the process by integer dividing this new dividend (167) by the divisor (23)
167/23 = 7
this 7 becomes the next digit in our quotient. and we repeat the process of multiplying this by the divisor and subtracting the result from the dividend. this gives us a remainder (6), and we pull down the next digit (9).
62.79 ÷ 23 = 2.7
- 46
---------
167
- 161
----------
69
and again, we repeat by integer dividing the new dividend (69) by the divisor (23)
69/23 = 3
this 3 is the next digit in our quotient.
we multiply it with the divisor and subtract the result from the dividend.
if the remainder is still not 0, we need to repeat the process by pulling the next digit, which would be an invisible 0. and continue.
but luckily, after this the remainder is 0, and we are finished.
62.79 ÷ 23 = 2.73
- 46
---------
167
- 161
----------

so, 62.79 ÷ 23 = 2.73 and 0 remainder.
