Answer:
The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
Step-by-step explanation:
Regression Output :
Predictor Coefficient
Constant 3.0979
Square root of items 2.7633
R.sq.- 96.7%
So, with this data the regression equation is,
\(\hat{y}=3.0979+2.7633x\)
Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items
Substitute x =22 in equation
\(\hat{y}=3.0979+2.7633(22)\)
\(\hat{y}=63.8905\)
Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

It can be seen that the graph increases linearly from {x} = - 12 to {x} = -2. It is a straight line between the points {x} = - 2 to {x} = 2. Then, it decreases linearly from {x} = 2 to {x} = 12. It crosses the {y} axis at the point (0, 4).

differentiate f(x) =5√x using first principle
Answer: To differentiate a function using the first principle, we first need to know the function and it's original value. Given that the function is f(x) = 5√x .
The first principle of differentiation states that the derivative of a function f(x) at a point x is approximately equal to the change in f(x) for an infinitesimal change in x. We can use this principle to find the derivative of a function f(x) at a point x by calculating the limit of the ratio (f(x+dx)-f(x))/dx as dx approaches zero.
To differentiate f(x) = 5√x with respect to x using the first principle, we take the following steps:
Find the change in f(x) as x changes by dx, which is f(x + dx) - f(x)
Divide that change by dx to find the slope of the function at that point
Take the limit of that slope as dx approaches zero
So:
f(x + dx) = 5√(x + dx)
f(x) = 5√x
change in f(x) = f(x + dx) - f(x) = 5√(x + dx) - 5√x
slope = change in f(x) / dx
= (5√(x + dx) - 5√x) / dx
The limit as dx approaches zero is the derivative of the function,
lim (dx->0) [(5√(x + dx) - 5√x) / dx]
= lim (dx->0) [(5(x+dx)^1/2 - 5x^1/2) / dx]
= 5 * lim (dx->0) [(x+dx)^1/2 - x^1/2] / dx
= 5 * (1/2)x^(-1/2)
So the derivative of the function f(x) = 5√x is (5/2)x^(-1/2)
This is the slope of the function at a point x, which is the rate of change of the function at that point x.

Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,
\( \frac{8 + 10}{8} = \frac{6 + x}{6} \)
\( \frac{18}{8} = \frac{6 + x}{6} \)
\( \frac{9}{4} = \frac{6 + x}{6} \)
Cross multiply
\( 9*6 = 4(6 + x) \)
\( 54 = 24 + 4x \)
Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x

x = 7.5

Neither the domain nor the range of the transformed function are the same as those of the parent function.

The domain of the transformed function is the same as the parent function, but the ranges of the functions are differe
Both the domain and range of the transformed function are the same as those of the parent function.
What are Range and Domain?
The collection of all potential output values that a function can generate given its domain is known as its range.
The set of all potential input values for which a function is specified is referred to as its domain.
The function that results from translating the left 5 units and reflecting the function f(x) = |x| across the y-axis is g(x) = |-x + 5|.
Since any real number's absolute value is always non-negative, the original function's domain is all real numbers, or f(x) = |x|.
A function's domain remains unaffected when it is reflected across the y-axis. Since all real numbers fall within the domain of the modified function g(x) = |-x + 5|, this is also true.
Since each real number's absolute value is always non-negative, the original function's range is also all non-negative real numbers, f(x) = |x|.
A function's sign is reversed when it is reflected across the y-axis. Since all non-negative real numbers fall within this range, the transformed function g(x) = |-x + 5| also has this range as well
So, the correct statement about the domain and range of each function is: Both the domain and range of the transformed function are the same as those of the parent function.

Given:
A line segment AB on a coordinate plane.
The rule of translation is
\(f(x,y)\to (x-6,y-3)\)
To find:
The coordinates of A' and B'.
Solution:
From the given graph, it is clear that the coordinates of A and B are A(1,3) and B(5,1).
The rule of translation is
\(f(x,y)\to (x-6,y-3)\)
Using this rule, we get
\(A(1,3)\to A'(1-6,3-3)\)
\(A(1,3)\to A'(-5,0)\)
And,
\(B(5,1)\to B'(5-6,1-3)\)
\(B(5,1)\to B'(-1,-2)\)
Therefore, the coordinates of A' and B' are A'(-5,0) and B'(-1,-2).

the desired accumulated amount is $ 80,0000 after 11 years invested in account with 7.3 % interest compounded monthly
The total compound interest is $981365.6
Compound Interest:
Compound interest is defined as interest that is earned not solely on the initial amount invested but also on any further interest.
The formula for annual compound interest is as follows:
FV = P (1+ r/m)^mt
Where:
FV - the future value of the investment, in our calculator it is the final balance
P - the initial balance (the value of the investment)
r - the annual interest rate (in decimal)
m - the number of times the interest is compounded per year (compounding frequency)
t - the numbers of years the money is invested for
Given,
Principal amount =$80,0000
Time = 11 years
Interest = 7.3%
compounding frequency = monthly
So, the compounding frequency is,
=> 1 year = 12 times
=> 7.3% = 7.3/100 = 0.073
Now apply the values on the formula,
FV = 80,0000 x (1 + (0.073/12)^(11 x 12)
FV = 80,0000 x (1.006083)^132
FV = 80,0000 x 2.226707
FV = 1781365.6
So, the interest is,
I = FV - P
=> I = 1781365.6 - 80,0000
=> I = 981365.6
Therefore, the compound interest is 981365.6
