Answer:
3.60555127...
Step-by-step explanation:
A function is expressed by the equation y=0.3x−6. For what value of the independent variable will the value of the function be equal to −6; −3; 0?
Answer:
0; 10; 20
Step-by-step explanation:
x is the independent variable
y is the dependent variable
y is dependent on x
a) For what value of the independent variable will the value of the function be equal to −6
y=0.3x−6
-6 = 0.3x-6
0=0.3x
x = 0
Therefore, if the independent variable is 0, the value of the function will be -6.
b) For what value of the independent variable will the value of the function be equal to −3
y=0.3x−6
-3 = 0.3x-6
0.3x = -3+6
0.3x = 3
x = 3/0.3
x = 10
Therefore, if the independent variable is 10, the value of the function will be -3.
c) For what value of the independent variable will the value of the function be equal to 0.
y=0.3x−6
0=0.3x-6
6 = 0.3x
x = 6/0.3
x = 20
Therefore, if the independent variable is 20, the value of the function will be 0.

HELP! Consider the function represented by the graph. On a coordinate plane, a straight line with a negative slope begins on the y-axis at (0, 9) and exits the plane at (8, 1). What is the domain of this function?
Answer:
{ x | x ≥ 0 }
Step-by-step explanation:
Given,
There is a straight line started from (0, 9) and passes through (8, 1),
∵ In the coordinate plan, the values of x are arranged in increasing order to the right side of the y-axis,
Thus, the line is defined for all real values of x greater than 0,
Hence, Domain of the line = All real numbers greater than equal to 0,
i.e. { x | x ≥ 0 }

A 2-column table with 8 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3, 4. The second column is labeled f of x with entries negative 2, 0, 2, 2, 0, negative 8, negative 10, negative 20. Which could be the entire interval over which the function, f(x), is positive? (–∞, 1) (–2, 1) (–∞, 0) (1, 4)
The entire interval over which the function, f(x), is positive is from (-2, 1), according to the provided table of function values.
Explanation:You are asking for the interval over which the function f(x) is positive based on the provided table of values.
A function is positive when its value, represented as f(x), is greater than 0. Looking at the table, f(x) is positive when x is in between -2 and 1. Therefore, the interval over which the function, f(x), is positive is from (-2, 1).
This can be confirmed visually if you were to plot the x-values with their corresponding f(x) values and look for the section of the graph where the curve is above the x-axis (y>0).

_______
2.5*10^-3 It's scientific notation and please explain your answer
Answer:
for the first one 9.407×10^−11
Step-by-step explanation:
Final answer:
To multiply numbers in scientific notation, multiply the coefficients and add the exponents. To divide, divide the coefficients and subtract the exponents. Ensure the final coefficient is between 1 and 10 for proper scientific notation.
Explanation:
To answer the question regarding scientific notation, I'll demonstrate the steps using the examples you provided. Remember that when multiplying numbers in scientific notation, you multiply the coefficients (the numbers in front) and then add the exponents.
(8.18 × 10^-6)(1.15 × 10^-5) = (8.18 × 1.15) × (10^-6 × 10^-5) = 9.407 × 10^-11. Since the coefficient 9.407 is between 1 and 10, this is in proper scientific notation.
To divide two numbers in scientific notation, you divide the coefficients and subtract the exponents: (1.15 × 10^-7) ÷ (2.5 × 10^-3) = (1.15 ÷ 2.5) × (10^-7 − (-3)) = 0.46 × 10^-4. Since the coefficient 0.46 is not between 1 and 10, we need to adjust it to proper scientific notation, which would be 4.6 × 10^-5.
name the property that is shown by the following expression (9x3)x4=9x(3x4)
the associative property is used.
Which property is used in the expression?
The Associative property of multiplication says that (a × b) × c = a × (b × c),
so we can perform the multiplication in any order we want.
If you look at the expression:
(9x3)x4=9x(3x4)
The difference is that first we start with the product 9×3, and in the right side the first product we need to solve is 3×4, so the associative property is used.
A carpenter goes through 2 2 ⁄6 boxes of nails finishing 3 1 ⁄4 rooves. How much would he use finishing 2 rooves?
Answer:
1 17/39 boxes.
Step-by-step explanation:
3 1/4 rooves requires 2 2/6 boxes
So 2 rooves require 2 * 2 2/6 / 3 1/4 boxes.
= 2 * 14/6 / 13/4
= 28/6 * 4/13
= 56/39
= 1 17/39 boxes.
The question involves calculation of usage rate per roof by dividing the total boxes used by the number of rooves completed and then applying that rate to determine number of boxes needed for 2 rooves.
Explanation:The question asks how many boxes of nails a carpenter would use for 2 rooves if he goes through 2 2/6 boxes to complete 3 1/4 rooves. To find out the number of boxes needed for 2 rooves, we need to calculate the rate of nail box usage per roof and then apply that rate to 2 rooves.
First, we simplify 2 2/6 to a mixed number: 2 1/3.
Then we divide the number of boxes by the number of rooves to get the usage rate per roof:
2 1/3 boxes ÷ 3 1/4 rooves = usage rate per roof.
Once we get the usage rate, we multiply it by 2 to find the boxes needed for 2 rooves.
This process involves converting mixed numbers to improper fractions, performing division, and then multiplication.

Helppppp! Angles PTQ and STR are vertical angles and congruent. Circle T is shown. Line segments T P, T Q, T R, and T S are radii. Lines are drawn to connect the points on the circle and form secants P Q, Q R, R S, and S P. Angles P T Q and S T R are congruent. Which chords are congruent? QP and SR QR and PR and RS PR and PS
Answer:
[tex]\overline{QP} = \overline{SR}[/tex]
Step-by-step explanation:
Given: ∠PTQ ≅ ∠STR and TP, TQ, TR and TS are radii of the circle.
If two angle are equal, then they are equal in size and their measurements are equal.
IF ∠PTQ ≅ ∠STR then they are also equal in their measurements.
Now, In ΔPTQ and ΔSTR
∠PTQ ≅ ∠STR (vertically opposite angle)
[tex]\overline{TQ} \cong \overline{ST}[/tex] (Radius of the circle are equal and congruent in length)
[tex]\overline{PT} \cong \overline{TR}[/tex] (Radius of the circle)
∴ ΔPTQ ≅ ΔSTR (SAS postulate)
∴ [tex]\overline{QP}\cong \overline{SR}[/tex] (corresponding sides of congruent triangle are equal and congruent).
You can use the fact that a closed figure made by connecting the adjacent end points of two equal and intersecting line segment is a rectangle.
Option A: [tex]\overline{QP} \: \rm and \: \overline{SR}\\[/tex]correct choice since the line segment QP is and line segment SR are congruent.
Given that:
Angles PTQ and STR are vertical angle and congruent.Circle T(centered at T).Line segments TP, TQ, TR, and TS are radii.How to find which lines are intersecting?Since angle PTQ and angle STR are congruent, thus we have:
PR and SQ as straight intersecting lines.
Due to angle PTS and angle QTR are opposite angles made by intersecting lines, we have them as congruent or say of equal measurement.
[tex]\angle PTS \cong \angle QTR[/tex]
Since [tex]\overline{TP} = \overline{TQ} = \overline{TR} = \overline{TS}[/tex], thus we have got:
[tex]\overline{PR} = \overline{SQ}[/tex] in measurement ( as PR is sum of PT and TR and same for SQ)
How is a rectangle made?"A closed figure made by connecting the adjacent end points of two equal and intersecting line segment is a rectangle", we have PQRS as a rectangle.
As a rectangle have opposite sides parallel and equal, we have got:
[tex]\overline{PQ} \cong \overline{SR}[/tex]
Thus, Option A: [tex]\overline{QP} \: \rm and \: \overline{SR}\\[/tex] is the correct choice since the line segment QP is and line segment SR are congruent.

The sale price of a swimming pool after 16.5% discount $1135.60. Find the original price of the pool
well, let's say the original price is "x", and thus is also the 100% price of the item, however the item is discounted by 16.5%, well 100% - 16.5% = 83.5%, so then the discounted price is really the 83.5% of the item, and we know that is $1135.60.
now, if 1135.60 is 83.5%, what is the 100% or namely "x"?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1135.60&83.5\\ x&100 \end{array}\implies \cfrac{1135.60}{x}=\cfrac{83.5}{100}\implies 113560 = 83.5x \\\\\\ \cfrac{113560}{83.5}=x\implies 1360 = x[/tex]
The original price of the swimming pool $1,360.
Original pool price=x
Percent discount=16.5% or 0.165
Sale price=$1135.60
Hence:
x-0.165(x)=$1135.60
x(1-0.165)=$1135.60
0.835x=$1135.60
Divide both side by 0.835x
x=$1135.60/0.835
x=$1,360
Inconclusion the original price of the swimming pool $1,360.

The elementary school students are putting on a play as a fundraiser. The student tickets cost $2.00 each and
the adult tickets cost $4 each. They sold 5 times as many student tickets as adult tickets. They made $140. How
many student and adult tickets were sold?
Answer:
850 for student and 850 for students
Step-by-step explanation:
Let student tickets sold be=x
and adult tickets sold=y
They sold 5 times as many student tickets as adult tickets.
i.e. x=5y
The student tickets cost $2.00 each and
the adult tickets cost $4 each.
They made $140.
i.e. 2x + 4y = 140
Dividing both sides by 6, we get
x + 2y = 70
or 5y + 2y= 70
i.e. 7y=70
i.e. y=10
x= 5y
⇒ x = 50
Hence, Student tickets sold= 50
and Adult tickets sold= 10
