Rachel worked 2.5 hours on Monday, 3.5 hours on Tuesday, 2 hours on Thursday, and 5 hours on Saturday. She is paid $10.66 per hour. How much money did Rachel earn that week?
Answers
Answer:
$138.58
Step-by-step explanation:
You would first set up an equation. You want to know how much money Rachel earned that week, so let's refer to that by using variable t for total money earned this week.
Next, we also know that Rachel is paid 10.66 per hour, so we'll be multiplying it by the number of hours she worked this week. This allows us to set our equation up as follows:
10.66(2.5+3.5+2+5) = t
You would now add like terms.
10.66(13) = t
You would now multiply 10.66 and 13(total number of hours worked this week).
This would get us 138.58, or the total numnber of money Rachel earned this week.

x = y² - 7 is the simplified inverse equation of the equation y = x² - 7.
What is Inverse function?Inverse function is a function which reverse one function to another.
If a function f takes the variable x to y, then the inverse of a function must takes y to x.
To get the inverse of the function, we have to interchange the variables.
Given equation is y = x² - 7
Now interchange the variable x to y and y to x,
we get x = y² - 7

Let's prove using A.P with a common difference (d) = 13
Let's say we want to find the second number
a + (n - 1)d
a = 13, n = 4, d = 13
.: S2= 13 + ( 2- 1)13
S2= 13 + (1) 13
S2= 13 + 13 = 26
Let's show using a G. P series.
S2 = arⁿ—¹
S2 = 13 × 2²—¹
S2 = 13 × 2¹
S2 = 13 × 2 = 26

the approximate number of months since the start of 2020.
Over what period was the value of the card declining?
Answers
To respond to the question, we must identify the m-values for which V(m) equation decreases. The value of the card decreased during the course of the time from January 2020 to July 2020 (about 7 months),
What is equation?A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.
We must identify the values of m for which the function V(m) is dropping in order to estimate the time span during which the value of the card was declining.
The function V(m)'s derivative is provided by:
V'(m) = 500m - 3,500
By setting V'(m) = 0 and solving for m, we may determine the crucial point(s):
500m - 3,500 = 0
m = 7
V''(m) = 500
To respond to the question, we must identify the m-values for which V(m) decreases. The value of the card decreased during the course of the time from January 2020 to July 2020 (about 7 months), as we know that V(m) is falling for m 7.

The least squares regression line minimizes the sum of the Group of answer choices differences between actual and predicted y values. absolute deviations between actual and predicted y values. absolute deviations between actual and predicted x values. squared differences between actual and predicted y values
Answers
Answer:
The least squares regression minimizes the sum of squared differences between actual and predicted y-values. This is the last option in your list of possible answers.
Step-by-step explanation:
Recall that when one performs the least square regression, one deals with what are called the "residuals". These are the differences in between the predicted "y-value" from the best fitting function, and the actual value of the dependent variable plotted (the actual y-value of the plotted points)
What the least square regression does is to find the best function parameters that minimize the sum of these squared residuals.

Answers
Valid step: Subtract 2 times Row 1 from Row 2. (Adding negative 2 times Row 1 to Row 2 would achieve the same result.)
To reduce the augmented matrix:
Square Row 1: This step is not valid in reducing the augmented matrix. Squaring a row would change the values and potentially lead to incorrect results.
Divide Row 2 by 2 times Row 1: This step is valid. Divide each element in Row 2 by 2 times the corresponding element in Row 1. This operation helps in achieving a leading 1 in the second row.
Multiply Row 1 by Column 1: This step is not valid in reducing the augmented matrix. Multiplying a row by a column does not have a defined operation in matrix reduction.
Add negative 3 times Row 3 to Row 2: This step is valid. Multiply Row 3 by -3 and then add it to Row 2. This operation helps in achieving zeros below the leading 1 in the second row.

8. Write a paragraph proof.
Proof Given: In a plane, a is perpendicular to b, b id perpendicular to c, and c || d.
Prove: a || d
Answers
To prove that line segment a is parallel to line segment d, based on the given information, we can utilize the properties of perpendicular and parallel lines.
Given that a is perpendicular to b and b is perpendicular to c, we know that angles formed between a and b, as well as between b and c, are right angles. Let's denote these angles as ∠1 and ∠2, respectively.
Now, since c is parallel to d, we can conclude that the corresponding angles ∠2 and ∠3, formed between c and d, are congruent.Considering the fact that ∠2 is a right angle, it can be inferred that ∠3 is also a right angle.
By transitivity, if ∠1 is a right angle and ∠3 is a right angle, then ∠1 and ∠3 are congruent.Since corresponding angles are congruent, and ∠1 and ∠3 are congruent, we can deduce that line segment a is parallel to line segment d.
Thus, we have successfully proven that a is parallel to d based on the given information and the properties of perpendicular and parallel lines.

A rectangle room is 1.2 times as long as it is wide, and it’s perimeter is 25. Find the dimensions
Answers
Answer:
Step-by-step explanation:
L = length W = width
Length is 1.2 times width ⇒ L = 1.2 x W = 1.2W
Perimeter = 2 x W + 2 x L
= 2W + 2L = 25
Substitute L = 1.2W into the equation for the perimeter and solve for W
2W + 2L = 25
2W + 2(1.2W) = 25
4.4W = 25
W = 25 ÷ 4.4 = 125/22
Now substitute found value of W into L = 1.2W to find L:

f(n+1)=f(n)-5. If f(1)=100, what is f(6)

Step-by-step explanation:
Given:
f(1) = 100
f(n+1) = f(n) - 5
Solve for:
f(6)
Solution:
f(1) = 100
f(2) = f(1) - 5 = 100 - 5 = 100 - 1 x 5 = f(1) - 1 x 5
f(3) = f(2) - 5 = 100 - 5 - 5 = 100 - 2 x 5 = f(1) - 2 x 5
...
f(n) = f(n - 1) - 5 = 100 - (n-1) x 5 = f(1) - (n-1) x 5
=> f(6) = f(1) - (6-1) x 5 = 100 - 5 x 5 = 100 - 25 = 75
Hope this helps!
