4.Erik works 42 hours a week making $11 hour? His employer pays time and a half for hours over 40. Find his gross pay.
Answer:
$473.00
Step-by-step explanation:
Regular pay = 11*40 = 440.00
Overtime = (11*1.5)*2 = 33.00
Gross = 440 + 33 = 473.00
250% of what number 152.5
Calculate the length of x.
Answer:
B
Step-by-step explanation:
Use the pythagorean theorem to find the hypotenuse. You can do this by squaring 12 and 11 (separately) and then adding those together. You'll get 265. However, since this is c squared and not c, you have to find the square root for the correct answer. The square root of 265 is approximately 16.28. Hope this helps!

How do the graphs of the functions differ from the graph of f(x)=3.5x^3?
For each function, select Steeper, Less steep, or Reflected over the x-axis to describe the differences between the graph of the function and the graph of f(x).
Select all answers that are correct.
Given:
The function is [tex]f(x)=3.5x^3[/tex].
To find:
Whether the given function is Steeper, Less steep, or Reflected over the x-axis to describe the other function.
Solution:
Transformation of function: If f(x) is function and
[tex]g(x)=a\ f(x)[/tex]
Here, a is vertical stretch or compression.
If 0<|a|<1, then g(x) is less steeper than f(x) because f(x) is vertically compressed.
If |a|>1, then g(x) is steeper than f(x) because f(x) is vertically stretched.
If a is negative, the f(x) is reflected over the x-axis, to get g(x).
On comparing the function [tex]p(x)=4.5x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 4.5>3.5 So, it is the case vertical stretched and p(x) is steeper than f(x).
On comparing the function [tex]q(x)=-x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get |-1|=1<3.5 So, it is the case vertical compression and q(x) is less steeper than f(x) and because of negative sign the function is reflected over axis.
On comparing the function [tex]r(x)=3x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 3<3.5 So, it is the case vertical compression and r(x) is less steeper than f(x).
Therefore, [tex]p(x)=4.5x^3[/tex] is steeper.
[tex]q(x)=-x^3[/tex] is less steep and reflected over the x-axis.
[tex]r(x)=3x^3[/tex] is less steep.

Triangle ABC has A(-3,6),B(2,1), and C(9,5) what the length of side AB? What the length BC what the length AC and what ABC
Answer:
AB = 5√2
AC = √145
BC = √65
Step-by-step explanation:
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
For AB A(-3,6),B(2,1),
AB = √(2+3)²+(1-6)²
AB = √(5)²+(-5)²
AB = √25+25
AB = √50
AB = 5√2
For AC A(-3,6) and C(9,5)
AC = √(9+3)²+(5-6)²
AC = √(12)²+(-1)²
AC = √144+1
AC = √145
For BC B(2,1), and C(9,5)
BC = √(9-2)²+(5-1)²
BC = √(7)²+(4)²
BC = √49+16
BC = √65
Since All the sides are difference, hence triangle ABC is a scalene triangle

The slope of the line tangent to the curve 3x^2-2xy+y^2=11 at the point (1, -2) is ?
Given :
A curve : 3x² - 2xy + y² = 11
To Find :
The slope of the line tangent to the curve 3x^2-2xy+y^2=11 at the point (1, -2).
Solution :
Differentiating given curve w.r.t x is :
6x - ( 2y + 2xy' ) + 2yy' = 11
Putting the point ( 1, -2) in above equation, we get :
6 - ( 2(-2) + 2y' ) - 4y' = 11
6 - ( -4 + 2y' ) - 4y' = 11
10 - 6y' = 11
6y' = -1
[tex]y' =\dfrac{-1}{6}[/tex]
Therefore, the slope of the line tangent to the given point is [tex]y' =\dfrac{-1}{6}[/tex] .
Answer:
5/3
Step-by-step explanation:
The previous explanation was incorrect because they forgot to differentiate the other side of the equation (11), which would actually become 0, and make the answer 5/3

[5y]^4 when y= 2 Evaluate the expression
Answer:
10000
Step-by-step explanation:
Well substitute it
(5*2)^4
now follow order of operations (Parenthesis, exponents, multipication-division left to right, etc.)
5*2=10
10^4=10000
so the answer would be
10000 if y is 2
Answer:
10,000
Step-by-step explanation:
First, let's do the brackets (because of PEMDAS). We know that y = 2, so we multiply 2 and 5 to get 10. Now, we have to solve 10^4. To get 10^4, multiply 10 by itself four times. That gets us 10,000.

5-37. Richard's strategy for changing a percent to a decimal is to put the decimal point in front of the percent
number. An example of his work is shown at right. Do you agree with Richard's method? Explain your reasoning.
8%=0.8
80%=0.80
800%=0.800
9514 1404 393
Answer:
no
Step-by-step explanation:
The percent symbol (%) is a shorthand way to write "divided by 100" (/100). The percent can be changed to a decimal by making that substitution.
8% = 8/100 = 0.08
80% = 80/100 = 0.80
800% = 800/100 = 8.00
Effectively, the change to a decimal is made by moving the decimal point two places to the left. Richard's strategy only works if the percentage has 2 digits left of its decimal point. It does not work in the general case.

Which of the following statements is NOT true?
1) A well-designed experiment is the only legitimate way to establish a cause-and-effect relationship between two variables.
2) We can use results from an observational study to test a claim about a population. 3) When an observational study has a large sample and follows people for many years, we can use the results to establish a cause-and-effect relationship between two variables.
4) When many observational studies together meet specific criteria, the results can provide varying degrees of evidence for a cause-and-effect relationship between two variables. But we should be cautious in interpreting such results.
