Answer: 4^3 * 5^3
Step-by-step explanation: 4 repeats itself 3 times and 5 repeats itself 3 times
4^3 * 5^3
Put the numbers in numerical order
4 comes before 5
Answer:
[tex] { 4}^{3} \times {5}^{3} [/tex]
Step-by-step explanation:
I'd assume your x's stand for multiplication, so using that logic there are three fours and three fives. Each being multiplied by itself, so the simplified/exponential version of the equation is:
[tex] {4}^{3} \times {5}^{3} [/tex]
Make sure you put in numerical order (4 goes before 5).

Rachel has a $10,000, three-year loan with an APR of 7.25%.
a. What is the monthly payment?
b. What is the total amount of the monthly payments?
c. What is the finance charge
Simple interest analysis reveals that
a) The installment was $321.53 per month.
b) The total amount of the payments is $11,575.
c) Interest was paid of $1,575.
How to find the Calculation?After t years, the amount of simple interest is calculated using:
A(t) = p(1 + rt)
that where:
The initial deposit is known as the primary, or P.
The interest rate in decimal form is r.
In this issue:
Hence, a $10,000 loan.
APR of 5.25%, which equals 3 years, therefore
Item c:
The result is A(3), so:
A(t) = P( 1 + rt)
A(3) = 10000[ 1 + 0.0525(3)]
A(3) = 11575
The total amount of the monthly installments is $11,575.
Item d:
I = A(3) - P = 11575 - 10000 = 1575
When interest is calculated, the principal is removed, so:
Interest was paid of $1,575.
Item b:
36 payments were made over a period of 3 years, or 3 x 12 months.
Item a:
11575/3 = 321.53
The amount due each month was $321.53.

(b) When did outpatient surgeries reach 60%?
(Round down to the nearest year.)
The percent of outpatient surgeries in 1996 is 68.99 % and outpatient surgeries reach is 1992.
What is exponential?
The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
total surgeries at hospitals is approximated by
f(x)=1314+303 Inx
A) this function predicts for the percent of outpatient surgeries in 1996 IS
x = 1996-1900 = 96.
So f(96) = -1314 + 303 ln(96) =68.99 %
b) f(x) = 60
60 = -1314 + 303 ln(x)
ln x = (1314+60)/303 = 4.53
x = 92.75.

To hire an accountant to prepare taxes costs a flat fee and an additional hourly rate. The amount the accountant costs can
be modeled by the function A(x) = 150 + 35x, where x represents the number of hours the accountant works to prepare the
taxes and 150 represents the flat fee. What is the value of A(220) and its interpretation?
OA(220) = 7850; If the accountant takes 220 hours to prepare the taxes, the cost will be $7,850.
OA(220) = 7850; If the accountant takes 7,850 hours to prepare the taxes, the cost will be $220.
OA(220) = 2; If the accountant takes 220 hours to prepare the taxes, the cost will be $2.
2
OA(220) = 2; If the account takes 2 hours to prepare the taxes, the cost will be $220.
A(220) = 7850; If the accountant takes 220 hours to prepare the taxes, the cost will be $7,850.
Hence option (A) is correct.
What is a linear equation in one variable?
The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

The area of a given triangle is 35 square meters. The height of the triangle is (g-11) meters and the base is (g- 8) meters.
area of triangle = (b × h) ÷ 2
where b is the base so (g - 8)m,
h is the height so (g - 11)m
and area is 35
35 = (g - 11) × (g - 8) /2
35 = g² - 19g + 88 / 2
35 = 1/2g² - 19/2g + 44
1/2g² - 19/2g + 9 = 0
use the quadratic formula to find the two values of g and you will get:
g = 18 and g = 1
if we use g as 1 we will get negative metres for the values for the base and height so we use g = 18 instead!
base = (18) - 8

height = (18) - 11

What is SAS property of triangle ?The property of a triangle whose two sides and the angle between these sides are stated is "SAS," which stands for "Side, Angle, Side". The SAS formula can be used to determine the area of a given triangle ABC with two known sides and an included angle between these sides.
Assume that the triangle's three sides are a, b, and c.
A SAS Triangle's perimeter
The following formula can be used to determine a triangle's area using SAS:
When sides "b" and "c" are known, along with angle A, the triangle's area is equal to: 1/2 bc sin(A)
The area of the triangle is equal to 1/2 ab sin(C) when sides 'b' and 'a' as well as included angle B are known
when sides "a" and "c" were added using SAS in triangle 1ΔMKN ~ ΔJKL
So, MN/KN = JL/KL
(x+1)/12 = (3x-2)/32
∴ 5x = 10 ⇒ x = 2
Using same property (SAS) in triangle 2
J = 80
∴ 30 = <x'
∵ in a triangle sum of angles is equal to 180° so, y' + <
J + 30 = 180
∴ <J = 80

The difference between the actual value of the response variable and the corresponding predicted value(regression error) using the multiple regression model is the correct option.
A residual is a measurement of the vertical distance between a point and the regression line. It is just the discrepancy between an actual value observed and a value that was projected.
To ensure that the requirements for making conclusions about the coefficients in a linear model have been met, one should always perform a residual analysis.
In regression analysis, a residual is the discrepancy between an observed value and a predicted value.
It is determined by,
Residual = Observed value – Predicted value
The residual is the discrepancy between the expected value and the actual value.
