The percent error of the measurement is 1.9%.
Given that, Harper measured a line to be 5.4 inches long.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
If the actual length of the line is 5.3 inches
So, the difference of length of line = 5.4-5.3
= 0.1
Now, the percent error = Difference in length of line/Actual length × 100
= 0.1/5.3 × 100
= 0.01887 × 100
= 1.9 %
Therefore, the percent error of the measurement is 1.9%.

what is the slope of line segment 7 ?
——PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((———
Answer:
The slope is 0 because it is a straight line
Step-by-step explanation:
Answer:
undefined.
Step-by-step explanation:
You could be really formal and use the slope formula
The y values are both the same -- 4.
The x values are 3.5 and 6.5
Therefore the slope is (6.5 - 3.5) / (4 - 4)
The denominator is 0
The slope is undefined because 3/0 is not very well behaved.
A horizontal line always gives an undefined amount.
Simplify the expression

Given that f(x)=4x3-12x2+10 and g(x)=x3 – 2x2 + 5x
The value of f(x)- g(x)= ax'+bx?+ cx+d. What are the values of the coefficients a,b,c,d?
Answer:
The values of a,b,c and d are as follows:
a = 3, b = -12, c = -5, d = 10
Step-by-step explanation:
Given functions are:
[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]
We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)
So,
[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]
Combining alike terms
[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]
Now it was given that:
f(x)- g(x)= ax^3+bx^2+ cx+d
By comparing both we get
a = 3, b = -12, c = -5, d = 10
Hence,
The values of a,b,c and d are as follows:
a = 3, b = -12, c = -5, d = 10

OD
2(8 + b) = 42
OE.
3(b - 4) = 20
Answer: C. 3(b-2)=24
Step-by-step explanation: See since b equals ten and by the rules of P.E.M.D.A.S the parenthesis/brackets comes first so 10-2 equals 8 and three times 8 is 24 therefore the answer is 24

Write the equation of the line fully simplified slope-intercept form
Answer:
y=mx+b
Step-by-step explanation:
Answer:
y = (5/2)x - 5
Step-by-step explanation:
SLOPE:
The slope is rise over run, and in this case (thanks to the graph), we can do the [difference of y] / [difference of x] pretty easily. This is 5 / 2
Y-INTERCEPT:
Y-intercept is simple: where the line touches the y-axis. This happens at y = -5.
Therefore, the equation y = (5/2)x - 5

Gabe bought five sacks of apples each sack weighed 12 lb he paid three for each pound of apples what was the total cost of all of the apples Gabe bought
Answer:
The cost of 12lbs of apples is $36.
Step-by-step explanation:
⟹ Lets Solve!
⟹ First we must define x and y.
x is the lb's of apples and y is the cost.
⟹ Now lets form our equation.
[tex]3x = y[/tex]
[tex]x = 12[/tex]
⟹ Since gabe bought 12 pounds of apples x = 12.
⟹ Now substitute x for 12.
[tex]3x = y[/tex]
[tex]3(12)= y[/tex]
⟹ Now multiply.
[tex]36 = y[/tex]
The cost of 12lbs of apples is $36.

Answer:
the awnser is c
Step-by-step explanation:
A- 100:1 would mean it is a 10000% markup
B- 1:100 lower than b so eliminate
C- 2:1 So a is double the amount of b so it's 100%
D- 1:2 B is 100% of a so it's flipped, not what question is asking for
So process of elimination shows that C is the correct awnser

[tex]\bold{204.4~and~217.6.}[/tex]Solution Steps:
First you need to solve the real inequality to understand how to find the rest of the possible equations.
Subtract 13.2 from both sides:
[tex]13.2-13.2=[/tex] Cancels Out[tex]217.6-13.2=204.4[/tex]So now we know the real answer, but now we must find all the possible solutions.
(Means anything greater than or equal to 217.6 when you plug it into x + 13.2 ≥ 217.6.)
Numbers that are greater than 378:
1.) [tex]204.4+13.2=217.6[/tex] ≥ [tex]217.6[/tex] (True)
2.) [tex]217.6+13.2=230.8[/tex] ≥ [tex]217.6[/tex] (True)
3.) [tex]204.3+13.2=217.5[/tex] ≥ [tex]217.6[/tex] (False)
4.) [tex]0+13.2=13.2[/tex] ≥ [tex]217.6[/tex] (False)
5.) [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex] (False)
6.) [tex]200.4+13.2=213.6[/tex] ≥ [tex]217.6[/tex] (False)
7.) [tex]-200+13.2=-186.8[/tex] ≥ [tex]217.6[/tex] (False)
8.) [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex] (False)

o 1,3
Answer: option B
Step-by-step explanation:
-4, 1, 3
The roots of the polynomial equation x³ - 7x = 6x - 12 is given by the values x = -4 , 1 , 3
What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the polynomial equation be represented as A
Now , the value of A is
x³ - 7x = 6x - 12 be equation (1)
Now , it can be represented as 2 equations of the form
A = x³ - 7x be equation (2)
And , B = 6x - 12 be equation (3)
On plotting the graphs of the two equations , we get
The point of intersection of the equations is at P ( -4 , -36 ) , Q ( 1 , -6 ) and R ( 3 , 6 )
Therefore , the x coordinates of the points are x = -4 , 1 , 3
Hence , the roots of the polynomial is x = -4 , 1 , 3
