The equation of graph is solved and graph that is used to model piece rate pay is the "piece rate" graph
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
The graph that is used to model piece rate pay is the "piece rate" graph. The piece rate graph shows how much money is earned for each unit of work completed. It is a linear graph with a slope that represents the rate of pay per unit of work completed.
The other graphs mentioned are used for different purposes:
A piecewise graph is used to represent a function that is defined by multiple equations on different intervals.
Hence , the graph is solved

Suppose you want to get a loan for $ 5 , 000 at an interest rate of 5.3 % for 2 years to be paid back in 24 monthly installments. Calculate this loan using simple interest. What is the amount of the monthly payments? Round the answer to the nearest cent (hundredth).
Answer:
monthly payment = $56.445
Step-by-step explanation:
given data
loan = $5000
interest rate r = 5.3 % = 0.053
time t = 2 year = 24 months
solution
we will use here amount of the monthly payments formula that is
monthly payment = principal × [tex]\frac{r}{1+(1-r)^{-t}}[/tex] ................1
put here value and we get

Answer:
Given a function y=f(x) its first derivative – the rate of change of y with respect to x – is defined by: dydx=limh→0[f(x+h)−f(x)h]. Finding the derivative of a function by computing this limit is known as differentiation from first principles
and put the formula answer will be there
Answer:
see explanation
Step-by-step explanation:
Given f(x) then the derivative f'(x) is
f'(x) = lim( h tends to 0 ) [tex]\frac{f(x+h)-f(x)}{h}[/tex]
= lim( h to 0 ) [tex]\frac{\frac{3}{x+h}-\frac{3}{x} }{h}[/tex]
= lim( h to 0 ) [tex]\frac{3x-3(x+h)}{hx(x+h)}[/tex]
= ( lim h to 0 ) [tex]\frac{3x-3x-3h}{hx(x+h)}[/tex]

Calculate the area of the square shown below.
its a square ■ and on the bottom its 3.1 yd what do I do?
Step-by-step explanation:
area of square is a^2
3.1yd^2=9.61yd^2
Answer:
Area = 9.61^2
Step-by-step explanation:
A square has all equal sides so each side is the same length. To find the area mulyiply the length by the width. Since it is a square both sides will be 3.1 yds long. So multiply 3.1 by 3.1 and you will get 9.61^2, That is the area of the square.
Write the slope-intercept form (y=mx+b) of the equation of the line through the given points.
through:
(0,3)(−4,5)
Step-by-step explanation:
General line equation: y = mx + c
When x = 0, y = 3. => (3) = m(0) + c, c = 3.
When x = -4, y = 5. => (5) = m(-4) + c,
5 = -4m + (3), -4m = 2, m = -0.5.
Hence the answer is y = -0.5x + 3.
Answer:
y=-[tex]\frac{1}{2}[/tex]+3
Step-by-step explanation:
To write the equation of the line in slope-intercept form, first calculate the slope of the line (m)
m=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
=[tex]\frac{5-3}{-4-0}[/tex]
=2/-4
=-[tex]\frac{1}{2}[/tex]
next, calculate b by substituting a point (0, 3) into the equation
y=mx+b
3=(-1/2)(0)+b
b=3
final equation of line is: y=-[tex]\frac{1}{2}[/tex]+3
Four different stores posted ads on special 15-oz cans of baked beans -8 for $6 = 75 cents per can -10 for $10 = $1 per can -2 for $3 = $1.50 per can -80 cents per can The last store listing was selling 28-oz of baked beans for $1.40 each. How does that price compare to the other prices?
Answer:
75 cents per can
Step-by-step explanation:
8 for $6 = 75 cents per can
10 for $10 = $1 per can
2 for $3 = $1.50 per can
The last store sold 28-oz for $1.40 each
To obtain the cost per 15-oz can of baked beans
28-oz / 15-oz = 1.86667of 15 - oz cans of baked beans can be obtained from 28 - oz.
The price per can will now be :
$1.40 / 1.8666666
= $0.75
= 0.75 * 100 = 75 cents
Hence, for the last store, they sold at 75 cents per can similar to the first store.

75

What is the measure of the marked angle? (photo included)
Answer:
B) 42 Degrees
Step-by-step explanation:
An angle bisector is basically a line that splits an angle into two congruent angles.
In this case, the large angle ABC is bisected by ray BD.
Angle ABC is given to be 84 degrees, so the measure of angle ABD is exactly half of that, or 42 degrees.

Pattern A start at 20 and has the rule subtract 2. Pattern b starts at 20 and has the rule subtract 1. Which shows the first several terms of patterns A and b
Answer:
c.
Pattern A: 20, 18, 16, 14, 12, 10
Pattern B: 20, 19, 18, 17, 16, 15
Step-by-step explanation:
Pattern A starts at 20 and the rule is to subtract 2. The terms will therefore be:
= 20, 18, 16, 14, 12, 10
The numbers above were gotten by subtracting 2 from each term for the next term.
Pattern B starts at 20 and the rule is to subtract 1. The terms will be:
= 20, 19, 18, 17, 16, 15
Correct option is therefore option C.

ground 6 metre from the wall. The other end just reaches a windowsill.
Calculate the height of the windowsill above the ground.
Answer:
b=2√7 ≈ 5.29 meters
Step-by-step explanation:
think of it like a right triangle like in the picture with 8metre ladder as the hypotenuse
a²+b²=c²
6²+b² =8²
b²= 8²-6²=28
b=√28 =2√7 ≈ 5.29 meters

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees Fahrenheit and C is degrees Celsius. What is the temperature (in degrees Fahrenheit) of water that is 10 degrees Celsius?
Answer:
The temperature is [tex]50^{\circ}F[/tex]
Step-by-step explanation:
Given
[tex]F= (C*1.8) + 32[/tex]
Required
Find F when [tex]C = 10[/tex]
[tex]F= (C*1.8) + 32[/tex]
Substitute 10 for C
[tex]F = 10 * 1.8 + 32[/tex]
[tex]F = 18 + 32[/tex]
[tex]F = 50[/tex]
This is circle theorems I am not rly good at this
Answer:
m∠BCD = 24°
Step-by-step explanation:
By the theorem,
"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."
m(∠BOD) = 2(m∠BFD)
= 2(78°)
= 156°
Therefore, m(arc BD) = m∠BOD = 156°
Since, m(arc BD) + m(arc BFD) = 360°
156° + m(arc BFD) = 360°
m(arc BFD) = 360 - 156
= 204°
Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".
m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]
= [tex]\frac{1}{2}[204 - 156][/tex]
= 24°

Answer:
x = 26°
Step-by-step explanation:
Let us solve the question
In the given figure
∵ The ray NC bisects ∠WNB
→ That means it divides the angle into two equal angles, ∠WNC and ∠CNB.
∴ m∠WNC = m∠CNB
∵ m∠WNC = 3v - 4
∵ m∠CNB = 2v + 6
→ Equate the measures of the two angles
∴ 3v - 4 = 2v + 6
→ Add 4 to both sides
∵ 3v - 4 + 4 = 2v + 6 + 4
∴ 3v = 2v + 10
→ Subtract 2v from both sides
∵ 3v - 2v = 2v - 2v + 10
∴ v = 10
∵ x = m∠WNC
∴ x = 3v - 4
→ Substitute v by 10
∵ x = 3(10) - 4
∴ x = 30 - 4
∴ x = 26°
Katie and Sunnie both have 20-gallon fish tanks that are leaking water! After 15 minutes, Katie's tank has leaked 43 gallon. After 20 minutes, Sunnie's tank has leaked 34 gallon. Which tank is leaking faster?
Answer:
Katie's gallon
Step-by-step explanation:
Katie and Sunnie both have 20-gallon fish tanks that are leaking water!
For Katie
After 15 minutes, Katie's tank has leaked 4/3 gallon.
The rate of leakage =
4/3 gallon × 15 minutes
= 16
For sunny
After 20 minutes, Sunnie's tank has leaked 3/4 gallon.
Her rate is given as:
= 3/4 gallon × 20 minutes
= 15
Therefore,
The tank that is leaking faster is Katie's gallon
Sue charges a flat rate of $20 plus $10 per hour it takes her to mow a lawn. Which equation shows the correct way to find the cost y of mowing a lawn for x hours.
Answer:

The graphs of [tex]y = x^2 - 7x + 7[/tex] and the line [tex]y = -3[/tex] intersect at two points. What is the sum of the x-coordinates of these two points?
Answer:
x = 5, x = 2
Step-by-step explanation:
y=x²-7x+7 but also y=-3
so x²-7x+7=-3
x²-7x+10=0
when factorising think about 2 numbers you multiply by each other tp give 10 but at the same time their sum is 7
-5x-2=10
-5+-2=-7
so (x-5)(x-2)=0
(note: multiply the two brackets to check if ur answer is correct and that it gives x²-7x+10=0)
x-5=0 so x=5
but also x-2=0 so x=2
