Final answer:
To plot a graph of the amount Betsy earns against the time she works, we'll put the hours worked on the x-axis and the amount earned on the y-axis. Betsy is paid $11.50 per hour and the equation for Betsy's earnings is Y = 11.50X.
Explanation:
To plot a graph of the amount Betsy earns against the time she works, we'll put the hours worked on the x-axis and the amount earned on the y-axis. In this case, Betsy worked an 8 hour shift and was paid $92.00. So, the point on the graph would be (8, 92). To find how much Betsy is paid per hour, we can divide the total amount earned by the number of hours worked. In this case, $92.00 divided by 8 hours equals $11.50 per hour.
Using the equation Y = MX + B, where Y is the amount earned, M is the rate per hour, X is the number of hours worked, and B is the y-intercept, we can write the equation for Betsy as Y = 11.50X + 0, since she doesn't have a one-time fee.

Start at the origin. Move 6 units to the left, then move 2 units up.
Start at the origin. Move 6 units up then move 2 units to the left
The first one. Start at origin. Move 6 units to the right and up 2 units
Answer:
Option 1 - Start at the origin. Move 6 units to the right, then move 2 units up.
Step-by-step explanation:
To find : Which set of directions correctly describes how to plot the point (6,2) on the coordinate plane?
Solution :
The point (6,2) means the x-coordinate is 6 and y-coordinate is 2.
According to graphing,
As the x-coordinate is positive it moves to right side.
So, From origin there is a shift of 6 units right.
As the y-coordinate is positive it moves to upward side.
So, From origin there is a shift of 2 units up.
Therefore, 'Start at the origin. Move 6 units to the right, then move 2 units up'.
Hence, Option 1 is correct.
Determine the Domain of the relation
{(x, y): y = x/x-8}
Answer:
Domain: (-∞ , 8) ∪ (8, +∞)
Step-by-step explanation:
Since denominator is x - 8 so x ≠ 8
If x = 8 then y = 8/0 : undefined.
Hence, the domain is all real numbers except 8
So
Domain: (-∞ , 8) ∪ (8, +∞)
Answer:
The correct answer is A) x does not equal 8
Step-by-step explanation:
In order to find gaps in the domain, we look for two things. The first we look for is negatives under square roots (which are not an issue here since there are none) and then we look for 0, denominators. So to find the gap, we set the denominator equal to 0 and see what the x value cannot be.
x - 8 = 0
x = 8
How to solve:
In(x+3) - In(x-1) = 3
Answer:
x = (e^3 +3)/(e^3 -1) ≈ 1.20958
Step-by-step explanation:
Take the antilog and solve in the usual way.
ln(x+3) -ln(x -1) = 3
ln((x +3)/(x -1)) = 3 . . . . rearrange to a single log
(x +3)/(x -1) = e^3 . . . . take the antilog
x +3 = e^3·(x -1)
3 +e^3 = x(e^3 -1)
x = (e^3 +3)/(e^3 -1) ≈ 1.20958

cube root
B.
square root
C.
piecewise
D.
step
Answer:
B. Square root
Step-by-step explanation:
using distance formula:
x = √z^2 - y^2
y = √z^2 - x^2
=> z = √x^2 + y^2
Answer:
Option B. square root
Step-by-step explanation:
An incoming airplane is x miles due North at A from the control tower and a second airplane is y miles East at B of the same control tower.
The shortest distance between the two airplanes is z miles.
By Pythagoras Theorem
z² = x² + y²
z = √(x² + y²)
So function which models the situation best is "square root".
Therefore, option B. square root is the answer.

Answer:
C. both student 1 and student 2
Step-by-step explanation:
Dilation does not change any angles, so the triangles are similar and the trig functions of corresponding angles will be identical.
The slope of CB is -1/3 and the slope of BA is 3, so they multiply together to give -1. That means the segments are at right angles and the triangle is a right triangle.
Both the premise and the conclusion of each student is correct.

Write the absolute value equations in the form |x−b|=c (where b is a number and c can be either number or expression) that have the following solution sets: One solution: x=23.
Answer:
|x -23| = 0
Step-by-step explanation:
In order for there to be one x-intercept, the x-intercept must be the vertex. The vertex of your form will be (b, c), and you want that to be (23, 0). Hence your equation is ...
|x -23| = 0
An absolute value equation with the single solution set x=23 can be expressed as |x-23|=0, where b=23 and c=0 in the formula |x-b|=c.
To write an absolute value equation with the solution set x=23, we need to express this in the form |x-b|=c. The value of c must be positive, as the absolute value is always non-negative, and b will be the number that x is being compared to within the absolute value.
In this case, since we only have a single solution, this means that b=23 and c=0 because we want the equation to be true only when x is exactly 23. Thus, the absolute value equation that has only the solution set x=23 is |x-23|=0.

Nolan used the following procedure to find an estimate for the square root of 18.
Step 1: Since 4^2=16 and 5^2= 25 and 16 < 18 < 25, the square root of 18 is between 4 and 5.
4.1^2=16.81
4.2^2=17.64
4.3^2=18.49
4.4^2=19.36
Step 3: Since 18.49 rounds to 18, 4.3 is the best approximation for the square root of 18.
In which step, if any, did Nolan make an error?
A) In step 1, the square root of 18.
is between 4 and 5 because the square root of 18 equals about 20 and 4 times 5= 20.
B) In step 2, he made a calculation error when squaring.
C) In step 3, he should have determined which square is closest to 18.
D) Nolan did not make an error.
Answer:
C) In step 3, he should have determined which square is closest to 18.
Step-by-step explanation:
17.64 also rounds to 18. 17.64 differs from 18 by ...
18 -17.64 = 0.36
whereas 18.49 differs from 18 by ...
18.49 -18 = 0.49
Hence 17.64 is closer to 18 and we might expect 4.2 to be closer to √18 than is 4.3.
___
The actual root of 18 is about 4.243, so 4.2 is a better approximation.
C) In step 3, he should have determined which square is closest to 18.

Isosceles △ABC (AC=BC) is inscribed in the circle k(O). Prove that the tangent to the circle at point C is parallel to AB .
Explanation:
Let M be the midpoint of AB. Then CM is the perpendicular bisector of AB. As such, center O is on CM, and OC is a radius (and CM). The tangent is perpendicular to that radius (and CM), so is parallel to AB, which is also perpendicular to CM.
If you need to go any further, you can show that triangles CMA and CMB are congruent, so (linear) angles CMA and CMB are congruent, hence both 90°.

What is the measure of angle x? please help
➷ First find the angle on the opposite side of x.
We can find this using the rule that angles on a straight line equal 180 degrees
180 - (90 + 47) = 43
Vertically opposite angles are equal
Therefore, x would also be 43 degrees.
✽➶ Hope This Helps You!
➶ Good Luck (:
➶ Have A Great Day ^-^
↬ ʜᴀɴɴᴀʜ ♡
Answer:
x=43
Step-by-step explanation:
The angle between x and 47 is a right angle because it is a vertical angle to the right angle and vertical angles are equal.
Starting with x, we add x + the right angle +47 and we have a straight line. We know straight lines are 180 degrees
x + 90 + 47 = straight line
x+ 137 = 180
Subtract 137 from each side
x+137-137 = 180-137
x = 43

a sprinkler that sprays water in a circular area can be adjusted to spray up to 30 feet. turning the radius-reduction screw on the top of the nozzle lets people the radius by up to 25 percent. to the nearest tenth, what is the maximum area of lawn that can be watered by the sprinkler if the radius-reduction is used at full capacity.
Answer:
1590.4 square ft
Step-by-step explanation:
r=30 so you need to multiply that by 25% (30*.25=7.5)
30-7.5=22.5
A= pi(r)^2
A=pi*(22.5)^2
A=506.25pi
A=1590.43 or 1590.4 (to the nearest tenth)
Answer: 1590.4 square feet
Step-by-step explanation:
Given: The radius of the circular area = 30 feet
Now, 25% of the radius = [tex]0.25\times30=7.5[/tex] feet
If the we reduce the radius by 25%, then the radius of the circular area =
[tex]30-7.5=22.5\text{ feet}[/tex]
Now, the circular area of the spray is given by :-
[tex]\text{Area}=\pi r^2\\\\\Rightarrow\text{ Area}=(3.143.141592653)(22.5)^2\\\\\Rightarrow\text{ Area}=1590.43128088\approx1590.4\text{ ft}^2[/tex]
Therefore, the maximum area of lawn that can be watered by the sprinkler if the radius-reduction is used at full capacity = 1590.4 square feet.

Answer: 90 pounds.
Step-by-step explanation:
Let's call:
A: pounds of type A coffee.
B: pounds of type B coffee.
Based on the information given in the problem you can set up the following system of equations:
[tex]\left \{ {{A+B=153} \atop {4.25A+5.45B=758.25}} \right.[/tex]
You can use the Elimination method:
- Multiply the first equation by -4.25.
- Add both equations.
- Solve for B.
Then, you obtain:
[tex]\left \{ {{-4.25A-4.25B=-650.25} \atop {4.25A+5.45B=758.25}} \right.\\----------\\1.2B=108\\B=90[/tex]
He used 90 pounds of type B coffee.
Answer:
B = 90 pounds
Step-by-step explanation:
We know that Han's Coffee shop uses coffee A at $4225 per pound and coffee B at $5.45 per pound and this month it made 153 pounds of blend for a total cost of $758.25.
We are find the number of pounds for coffee B used.
[tex]A+B=153[/tex]
[tex]A=153-B[/tex] --- (1)
[tex]4.25A+5.45B =758.25[/tex] --- (2)
Substituting equation (1) in (2) to get:
[tex]4.25(153-B)+5.45B=758.25[/tex]
[tex]650.25-4.25B+5.45B=758.25[/tex]
[tex]1.2B=758.25-650.25[/tex]
[tex]1.2B=108[/tex]
B = 90 pounds
A farm supply store sells a variety of treat balls for small and large animals. Martha wants to purchase a ball that can hold 1437 cubic centimeters of treats. What is the diameter of the ball she should purchase? Round to the nearest whole number.
The volume of a sphere is v=4/3 x 3.14 r to the the third power
Answer: 14 centimeters.
Step-by-step explanation:
You need to use the formula for calculate the volume of a sphere:
[tex]V=\frac{4}{3}(3.14r^3)[/tex]
Where the radius of the sphere is "r".
As you know the volume of the ball, you can susbtitute it into the formula [tex]V=\frac{4}{3}(3.14r^3)[/tex], and solve for the radius "r":
[tex]1437=\frac{4}{3}(3.14r^3)\\\\3( 1437)=4(3.14r^3)\\\\4311=12.56r^3\\\\r=\sqrt[3]{\frac{4311}{12.56}}\\\\r=7.0cm[/tex]
The diameter of the ball can be calculated with:
[tex]D=2r[/tex]
Where r is the radius of the ball.
Substituting the radius of the ball into [tex]D=2r[/tex], you get that the diameter of the ball that she should purchase, rounded to the nearest whole number, is:
[tex]D=2(7.0cm)\\D=14.0cm\\D=14cm[/tex]
Final answer:
To solve for the diameter of the ball, the volume of a sphere formula is used. The calculated diameter is rounded to the nearest whole number, and Martha should purchase a treat ball with a diameter of approximately 14 centimeters.
Explanation:
To find the diameter of the ball that can hold 1437 cubic centimeters of treats, we need to use the formula for the volume of a sphere: V = (4/3) π r^3, where V is the volume and r is the radius. We will solve for r and then multiply by 2 to find the diameter. Given that the volume, V, is 1437 cubic centimeters, the formula becomes:
1437 = (4/3) × 3.14 × r^3
To isolate r, we first divide both sides of the equation by (4/3) × 3.14:
r^3 = 1437 / ((4/3) × 3.14)
Calculating the right side gives us the approximate value of r^3. Then, we take the cube root of both sides to solve for r:
r = ∛(1437 / ((4/3) × 3.14))
Once we find r, we can calculate the diameter, D, by:
D = 2 × r
Calculating the above with the given volume, we find:
r ≈ ∛(1437 / ((4/3) × 3.14)) ≈ 6.83 cm
D ≈ 2 × 6.83 cm ≈ 13.66 cm
So, rounding the diameter to the nearest whole number, Martha should purchase a treat ball with a diameter of approximately 14 centimeters.
A small island in the middle of a river is eroding away. Each year, the island has 85% of the area from the previous year. After one year the island has an area of 10.2 thousand square yards. Graph the sequence and describe the pattern. How much of the island is left after 6 years?
Answer:

B. Y+5= (-2/5) x+3)
C. Y-5= -2/5 (x+3)
D. Y-5= -2/5 (x-3)
To write an equation in point slope form, we use the formula: y - y1 = m(x - x1). The correct equations are: Y + 3 = 6(x - 8) and Y + 5 = -2/5(x + 3).
Explanation:To write an equation in point slope form, we use the formula: y - y1 = m(x - x1). Where (x1, y1) is the given point and m is the given slope.
Question 1:
Given point: (8, 3) and slope: 6
Substituting the values into the formula, we have: y - 3 = 6(x - 8)
Therefore, the correct answer is option A: Y + 3 = 6(x - 8).
Question 2:
Given point: (-3, -5) and slope: -2/5
Substituting the values into the formula, we have: y + 5 = -2/5(x + 3)
Therefore, the correct answer is option A: Y + 5 = -2/5(x + 3).
Final answer:
The point-slope form equations for the given points and slopes are y - 3 = 6(x - 8) for the first set and y + 5 = (-2/5)(x + 3) for the second set.
Explanation:
The equation of a line in point-slope form is written as y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a given point on the line.
1. With the given point (8,3) and slope m = 6, the equation in point-slope form will be y - 3 = 6(x - 8). This corresponds to option B. Y-3=6(x-8).
2. For the given point (-3,-5) and slope m = -2/5, the point-slope form of the equation is y + 5 = (-2/5)(x + 3), which matches option A. Y+5= -2/5(x+3).
find the missing measure for the cone. round your answer to the nearest tenth.
diameter = 6 cm
height = _____ cm
volume = 84.78 cm3
Final answer:
To find the missing height of a cone with a given diameter of 6 cm and volume of 84.78 cm³, the volume formula for a cone is used, and after plugging in the known values, solving for the height gives an approximate value of 3.0 cm when rounded to the nearest tenth.
Explanation:
The student is asking for the missing height of a cone given the diameter and the volume. The formula to calculate the volume of a cone is V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height of the cone. Since the diameter is given as 6 cm, the radius is half of that, which is 3 cm. The known volume of the cone is 84.78 cm³. Plugging these values into the formula gives:
84.78 cm³ = (1/3)π(3 cm)²h
After solving for h, we get:
h = ³ × 84.78 cm³ / (π × (3 cm)²)
h = 84.78 cm³ / (9π cm²)
h = 84.78 / (9 × 3.14159)
Now calculating h and rounding to the nearest tenth:
h = 84.78 / 28.27431
h ≈ 3.0 cm
Therefore, the height of the cone is approximately 3.0 cm.
Put this into Y=Mx+B form please
Is this right idk but i need work fir it
Answer:
The answer is C 5/4
Step-by-step explanation:
When lines are parallel and you know there is a scalar factor, make the ratio by putting the original over the dilation 15:12 or 15/12 this is the ratio and after you need to reduce by dividing by the greatest common factor. 15 and 12's GCF is 3 so (15/3)/(12/3) = 5/4.
Remove the parentheses from the following expression: (+6) – (+2)
A. –6 – 2
B. 6 – 2
C. –6 + 3
D. 6 + 2
The correct answer:
B. 6 - 2
Answer:
B. 6-2
Step-by-step explanation:
We have been given expression : [tex]\left(+6\right)-\left(+2\right)[/tex]
Now we need to rewrite that expression [tex]\left(+6\right)-\left(+2\right)[/tex], without parenthesis then select which of the given choices are correct.
[tex]\left(+6\right)-\left(+2\right)[/tex]
We know that product of opposite sign is always negative sign.
Then product of - and +2 gives -2
So we can rewrite the problem as:
[tex]=6-2[/tex]
Hence choice B. 6-2 is the final answer.
