Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime, how much did he earn?
Answers
When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2
Given,
The amount he earns in an hour = $5.40
Total number of hours he worked =40 hours
The amount he earns = 5.40×40 = $216
Overtime hours = 2 hours
Overtime payment per hour= 5.40×1.5= $8.1
The amount he earns for overtime = 2×8.1= $16.2
The total amount he earned = 216+16.2= $232.2
Hence, when Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

f(x) = 8x

Find (f g)(x)
f(x)= 14
g(x)= 3 - 12x
find f(x) • g(x)
please, it’s for tomorrow and i need whit the process
Answers
a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
In this question, we have been given two functions.
We need to find the given function.
a) f(x) = 8x and g(x) = 12x + 3
To find (f g)(x)
We know that, the product of functions f(x) and g(x) is:
(f g)(x) = f(x) . g(x)
(f g)(x) = (8x) (12x + 3)
(f g)(x) = 96x² + 24x
So, for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) f(x)= 14 and g(x)= 3 - 12x
To find f(x) • g(x)
f(x) • g(x) = (14) . (3 - 12x)
f(x) • g(x) = 42 - 168x
So, for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x

a. First graph the system in a standard window. Can you see the solution on your screen?
b. To find the solution you will need to change the window on your calculator. Discuss with your team what maximum value, minimum value, and scale
you should use for the 2- and y-axes in order to see the intersection. After you have decided, check your conclusion on the graphing calculator.
c. Use a "trace" function on your calculator to find the solution from the graphs. Then solve the system algebraically.
d. Discuss the two methods with your team. Explain which one your team prefers and why.
Answers
The solution for the system of equation is 4534 and the graphical representation is attached below.
A system of equation or simultaneous equations are a pair of linear equation is 2 variables such that they represent a pair of straight line sin the cartesian plane.
The point of intersection of these two line on the cartesian plane is given by the solution of the two equation that are given.
A system of equations can be solved algebraically by matrix method , elimination method or by substitution.
Now let us solve the given equation algebraically by elimination method.
5x - y = 35
3x + y = -3
Adding the equation we get:
or, 8 x = 32
or, x = 4
putting the value of x in the first equation we get:
5 × 4 - y = 35
or, -y = 35 - 20
or, y = -15
Hence the point of intersection is ( 4 , -15 )

Harry is saving for the deposit for an apartment. He has 21 350 EUR, but needs at least 30

He compares banks that offer annual interest compounded monthly.
What is the minimum interest rate he requires to meet his needs? Give your answer to three
significant figures.
[Answer format: 00.0%]
Answers
We need to know about the concept of compound interest to solve the given problem. The minimum interest rate that Harry needs to meet his need is 11.4%
Compound interest can be described as the interest that you earn on both the principal amount and the interest earned. In this question it is said that the bank offers annual interest compounded monthly, we will be using a formula to solve this problem. Since Harry has 21350 EUR we will take that as the principal amount and the minimum amount that he needs is 30000 EUR we will consider this to be the final amount at the end of 3 years. We need to find out the rate of interest that the bank offers.
A=P[tex](1+\frac{r}{12} )^{12t}[/tex] where A is amount, P is principal, r is the rate of interest and t is time period.
P=21350 EUR
A=30000 EUR
t=3
30000=21350[tex](1+\frac{r}{12}) ^{36}[/tex]
[tex]\frac{600}{427} =(1+\frac{r}{12}) ^{36}[/tex]
1+[tex]\frac{r}{12}[/tex]=1.00949
r/12=0.00949
r=0.1139
r=11.4%
Therefore we found that the minimum rate of interest Harry requires to meet his needs is 11.4%

Malia uses 51 yards of ribbon to make 17 bows. the relationship between ribbon and bows is proportional. how many yards of ribbon does malia need to make 68 bows?
Answers
Malia that uses 51 yards of ribbon to make 17 bows will have to use 204 yards of ribbon to make 68 bows
To solve this problem we will use a rule of three with the problem information:
17 bows-------- 51 yards of ribbon
68 bows-------- x
Applying the rule of three we get:
x = (68 bows * 51 yards of ribbon) /17 bows
x = 204 yards of ribbon
What is rule of three?It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.

c. Would the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry? Explain.
Answers
The fact that the sum of the interior angles of a triangle add up to 180 is equivalent to the parallel postulate. Therefore, the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry.
How to illustrate the information?There is only one parallel to the given line in Riemannian geometry. A straight line of finite length that can be continued endlessly is the second postulate of Euclid.
One of the non-Euclidean geometries that entirely rejects the validity of Euclid's fifth postulate and alters his second postulate is Riemannian geometry, commonly known as elliptic geometry. The fifth postulate of Euclid states that there is only one line that passes through a point that is not on a particular line and is parallel to that line.
In this case, the angles won't change as it's always equal

The given function is [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex]
Domain: The domain of a function is the set of input or argument values for which the function is real.
Use commutative properties to reorder the terms
[tex]\[f(x) = \sqrt { - x + 2} - {x^2}\][/tex]
Separate the function into parts to determine the domain of each part
[tex]\[f\left( x \right) = \sqrt { - x + 2} \]=-x+2= x^{2}[/tex]
Domain is XR (all real numbers)
The function has no undefined points nor domain constraints. Therefore, the domain is X∈R.
Range: The set of values of the dependent variable for which a function is defined
Range of [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\][/tex]
Combine the ranges of all domain intervals to obtain the function range.
Hence, the domain and the range of the function [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex] are

Find the equation of the line which passes through (6,2) and is parallel to the line with equation 3y=5x+2

Answer:
3y = 5x - 24
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3y = 5x + 2 ( divide through by 3 )
y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex]
• Parallel lines have equal slopes , then
y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line
to find c substitute (6, 2 ) into the partial equation

multiply through by 3 to clear the fraction
