Based on the first entry level web developer salary paid, and the new work year, the amount the web developer can expect his annual pay to decrease by is $2,190
How to find the decrease in pay?First, find the weekly pay of the web developer in the first salary:
= 56,940 / 52
= $1,095 per week
The new salary of the web developer as a result of the work week becoming 50 weeks is:
= 1,095 x 50
= $54,750
The decrease in this annual pay to the web developer is:
= 56,940 - 54,750
= $2,190

Hope this helps!
The solution to the given inequality [tex]3x \leq -54[/tex] is [tex]x \leq \frac{-54}{3}[/tex] .
Inequality is a fine statement that compares two values, showing if one is lower than, lesser than, or simply not equal to another value. Inequalities are frequently used to represent connections between amounts, similar to the relationship between the height and weight of a person, or the relationship between the speed and time of an object in stir.
We first divide the inequality [tex]3x \leq -54[/tex] by 3 on both sides to obtain:
[tex]x \leq \frac{-54}{3}[/tex] .
Then, we plot the line [tex]x = \frac{-54}{3}[/tex] on the graph. The region left to the line thus obtained is the solution of the given question.
Thus, the line [tex]x \leq \frac{-54}{3}[/tex] is plotted in the graph.

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary.
The answer is 16.4
Answer:
x = 16.4
Step-by-step explanation:
From the diagram, we can see that the radius of the circle is 19.4 as the line labelled 19.4 goes from the centre to the edge of the circle.
Therefore the length of the line marked in green is also 19.4 units, as it is also a radius of the circle.
Now we can simply use the Pythagorean Theorem to calculate the value of [tex]x[/tex]:
[tex]19.4^2 = x^2 + 10.3^2[/tex]
⇒ [tex]x^2 = 19.4^2 - 10.3^2[/tex]
⇒ [tex]x = \sqrt{19.4^2 - 10.3^2}[/tex]
⇒ [tex]x = \bf 16.4[/tex]
Therefore the length of the indicated segment is 16.4 units.

Martin earned $8.75 an hour plus another $18 in tips. Lawrence earned $9.25 an hour and spent $2 on a soda. Lawrence had more money than Martin. Let x represent the number of hours worked.
If Martin earned $8.75 an hour plus another $18 in tip and Lawrence earned $9.25 an hour and spent $2 on a soda, then the inequality represents the situation is 8.75x+18 < 9.25x-2
The payment of Martin per hour = $8.75
The addition tip he got = $18
The payment of Lawrence per hour = $9.25
The amount he spend for soda = $2
x represents the number of hours worked
Lawrence had more money than Martin
Then the inequality will be
8.75x+18 < 9.25x-2
Hence, if Martin earned $8.75 an hour plus another $18 in tip and Lawrence earned $9.25 an hour and spent $2 on a soda, then the inequality represents the situation is 8.75x+18 < 9.25x-2

Consider this function f(x) = x -4
The inverse of the given function is f-1(x)= x²+4.
What is inverse of a function?A function that "undoes" another function in mathematics is known as an inverse. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f-1.
To calculate the inverse of a function:
Consider f(x)=y
And interchange the variables.
So given f(x)= √x-4 becomes
y=√x-4 ⇒ x=√y-4
Now on squaring both sides we get,
x²= y-4
⇒ y = x²+4
Replace y by f-1(x)
So the equation becomes,
f-1(x) = x²+4

Answer:
x = 18
Step-by-step explanation:
the angles pictured are supplementary angles.
supplementary angles are angles whose sum equals 180°
ex: <1 + <2 = 180°
[tex]5x - 11 + 6x - 7 = 180[/tex]
[tex]11x - 18 = 180[/tex]
[tex]11x = 198\\x = 18[/tex]
Answer:
[tex]\boxed{\sf{x=18}}[/tex]
Step-by-step explanation:
To find the value of x, you have to use the supplementary angles which is equal to 180°.
Supplementary angles = 180°
5x-11+6x-7=180
Combine like terms.
[tex]\sf{5x+6x-11-7=180}[/tex]
5x+6x=11x
[tex]\sf{11x-11-7=180}[/tex]
Subtract the numbers from left to right.
-11-7=-18
[tex]\sf{11x-18=180}[/tex]
You have to add by 18 from both sides.
11x-18+18=180+18
Solve.
Add the numbers from left to right.
180+18=198
11x=198
Divide by 11 from both sides.
11x/11=198/11
Solve.
198/11=18

State the degree and end behavior of f(x)=8x³+2x⁴-5x²+9. Explain or show your reasoning.
Examining the given polynomial we arrive at the various parameters
the polynomial is degree 4The end behavior is x → ∞ f(x) → ∞, x → - ∞ f(x) → ∞How to find the degree of a polynomialThe degree refers to the maximum power to which the equation is raised. We can see that the term 2x⁴ bears the maximum power and it is 4 hence the equation is degree 4
How to find the end behavior of a polynomialThe end behavior refers to how the equation relates at the extremes. The extremes a big positive value and big negative value.
Big positive value say x = 1000
f(x)=8x³+2x⁴-5x²+9
f(1000) = 2.008x10^12
Big negative value say x = -1000
f(x)=8x³+2x⁴-5x²+9
f(-1000) = 1.992x10^12

a gigabyte of computer storage space is 2^30 bytes.A computer has a total storage space of 128 gigabytes.How many bytes of total storage space does the computer have?Write your answer as a power.
There are 2 ³⁷ bytes in 128 gigabytes.
Bytes, which typically contain eight bits, are the basic building blocks of digital information.
Because previously a single character of∀⊅ text required only a certain number of bits to be encoded in a computer, the byte is the lowest addressable unit of memory in all computer systems. To distinguish them from the standard 8-bit definition, network protocol documents like The Internet Protocol (RFC 791) refer to an 8-bit byte as an octet. An octet's bits are commonly counted from 0 to 7 or 7 to 0, depending on the bit endianness. The eighth bit is a seven since the first bit is a zero.We know that 128 = 2⁷
Now each gigabyte = 2³⁰ bytes
So the total number of bytes in 128 gb is
2⁷ × 2³⁰ = 2³⁰⁺⁷ = 2 ³⁷
Therefore there are 2³⁷ bytes in 128 gigabytes.

Area of a parallelogram is A = bh
Find b and h where the area is 20 square inches
So, to find the equal value of both b and h take square root of 20
➟ √20

1) Mrs. Martins deposits $2,650 into a savings account. The account earns 6%
interest per year, and the interest is not compounded. How much amount will
be in the account after 9 years?
The amount in the savings account of Mrs. Martins after 9 years will be $4081.
According to the question,
We have the following details:
The amount deposited in the savings account or the principal amount = $2,650
Interest per year = 6%
Time = 9 years
(It is given that the interest is not compounded.)
Now, using the formula of simple interest, we will first find the total interest after 9 years,
Simple Interest (S.I.) = (Principal * Rate * Time)/100
S.I. = (2650*6*9)/100
S.I. = (2650*54)/100
S.I. = 143100/100
S..I. = $ 1,431
Now, the total amount in the savings account would be the sum of the principal amount and the total interest.
So, we have:
Total amount = Principal + S.I.
Total amount = $ (2,650+1,431)
Total amount = $ 4,081
Hence, the total amount in Mrs. Martins's savings account is $ 4,081.

A large container is being filled with water at the rate of 2 3/4 per minute
Answer:
5 minutes and 20 seconds
Step-by-step explanation:
basically your equation is: (rate of filling container) x (time to fill container)
- (minus)
(rate of leaking from container) x (time to fill container)
=
(the size of the container in gallons)
--------------------
step 1 - so t = the time in minutes to fill14 gallon container
step 2 - convert 2 3/4 to quarters so:
2 • 4 = 8 and it’s in quarters so 8/4 then
8/4 + remaining 3/4 = 11/4
step 3 - so then you fill in the equation:(11/4)•t - (1/8)•t = 14
step 4 - multiply both sides of the equation by 8:
(11/4) = 2.75 • 8 = 22
(1/8) = 0.125 • 8 = 114 • 8 = 112
so the equation is:
22t - t = 112
step 5 - divide both sides of the equation by 22:
22t / 22 = t
112 / 22 = 5.333
so t = 5.333
step 6 - convert
so 5.333 has a repeating decimal of 0.3 which is 1/3. so to convert that to seconds, take 1/3 of 60:
60 / 3 = 20
so it takes 5 minutes and 20 seconds to fill the 14 gallon container

Find all horizontal asymptotes of the following function.
f(x) =3x² - 48/2x+8
The given function f(x) =3x² - 48/2x+8 has no Horizontal asymptote.
A horizontal asymptote may be defined as a horizontal line at which the graph of the function will appear to meet but will not actually meet. It is a tool to determine the end behavior of the function. We are given the function f(x) = 3x² - 48/2x+8. Now to find horizontal asymptote of this function we first find lim ₓ→∞ f(x) that is
lim ₓ→∞ (3x² - 48)/(2x + 8)
lim ₓ→∞ 3/2(x - 4) = ∞
Now, we calculate lim ₓ→-∞ f(x) that is
lim ₓ→-∞ (3x² - 48)/(2x + 8)
lim ₓ→-∞ 3/2(x - 4) = -∞
Since, both the limits are different therefore function does not have any horizontal asymptote.
