What is equation of a straight line ?The general equation of a straight line is y = mx + c, where m is the gradient or slope, and y = c is the value where the line cuts the y-axis. This number c is called as intercept.
From the question,
Parallel lines have same slope.
The slope given, m =3.
The function's graph is parallel to this line is 3x.
Hence the required answer is f(x)= 3x.

The answer is c
Step-by-step explanation:
which answer is right?
Answer: D
Step-by-step explanation:
Since we know that the area of the square is 900 in², we can use that to find the length of each side.
900=x² [square root both sides]
x=30
Now that we know each side is 30 in, we know that the diameter of the circle is also 30 in. To find the radius, divide the diameter by 2.
2r=30 [divide both sides by 2]
r=15
With the radius, we can find the area of the circle.
A=π(15)² [exponent]
A=225π
Since the problem said to leave in terms of π, the area is A=225π in².

Differentiate the function. f(x) = sin(9 ln(x))
Answer: [tex]f'(x)=\dfrac{9\cos(9\ln (x))}{x}[/tex].
Step-by-step explanation:
The given function is
[tex]f(x)=\sin(9\ln (x))[/tex]
Using chain rule differentiate w.r.t. x.
[tex]f'(x)=\cos(9\ln (x))\dfrac{d}{dx}(9\ln (x))[/tex] [tex]\left[\because \dfrac{d}{dx}\sin x=\cos x\right][/tex]
[tex]f'(x)=\cos(9\ln (x))\left[9\dfrac{d}{dx}(\ln (x))\right][/tex]
[tex]f'(x)=\cos(9\ln (x))\left[9\times \dfrac{1}{x}\right][/tex] [tex]\left[\because \dfrac{d}{dx}\ln x=\dfrac{1}{x}\right][/tex]
[tex]f'(x)=\dfrac{9\cos(9\ln (x))}{x}[/tex]
Therefore, [tex]f'(x)=\dfrac{9\cos(9\ln (x))}{x}[/tex].

plsss i really need help! How many unique handshakes can be made between 5 people? if you help me ill give u brainliest!
Answer:
10
Step-by-step explanation:
This is called a combination. Imagine you draw a figure, with a number representing each person, as shown below:
1 2 3 4 5
Person 1 can shake person 2, 3, 4, and 5's hands, for a total of 4 handshakes.
Person 2 can shake 3, 4, and 5's hands, for a total of 3 handshakes.
Person 3 can shake 4 and 5's hands, for a total of 2 handshakes.
Person 4 can only shake 5's hand, which is 1 handshake.
Last you add up the handshakes from every person, 4+3+2+1, which is equal to ten unique handshakes.

Help. Your backyard is 17 feet longer than it is wide. Its area is 7068 square feet. Its width is Solve by using quadratic equation.
Answer: Width=76 ft
Step-by-step explanation:
Let x = width, then x+17=length
Solve:
(x+17)x=7086
x²+17x=7086
x²+17x-7086=0
(x-76)(x+93)=0 ⇔ This is rounded to the nearest integer
x=76 or x=-93 (rej) ⇔ A length cannot be negative.

A certain analog clock runs fast and gains 5 minutes every 8 hours. It was set to show the correct time. What is the shortest interval of time after which the clock will show the correct time again?
Answer:
1152 hours
Step-by-step explanation:
It doesn’t mention that it has AM or PM, so we’re assuming that it’s just the same time, regardless if the clocks actually shows the wrong time in am/pm-wise.
So, if it gains 5 minutes every 8 hours, we have to make see how many 5-minutes that we need to make 12 hours. 12 hours is equal to 720 minutes, so 720/5=144. Since it asks how many hours we need for it to become the same time again, we need to add the fact that it only adds 5 minutes every 8 hours. Henceforth, we need to multiply our answer (144) by 8 hours. 144*8=1152. Your answer is 1152 hours.

The shortest interval of time after which the clock will show the correct time again is 144 hours.
Given that a certain analog clock runs fast and gains 5 minutes every 8 hours, and it was set to show the correct time, to determine what is the shortest interval of time after which the clock will show the correct time again the following calculation must be done:
A clock has a duration of 12 hours, that is, it makes a full turn in that time. Thus, the advance time must be 12 hours for the marked time to be correct.
5 minutes = 1/12 hour 12 hours = 1 hour in advance 12 x 12 = X 144 = X
Therefore, the shortest interval of time after which the clock will show the correct time again is 144 hours.

Answer:
1= 6x2
2= -6b3
Step-by-step explanation:
The missing value in the first equation is 6x² while in the second it is -6b³ - 5b² + 562.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given first equation,
(-4x² + 6x + 3) + (8x + 5 + ?) = 2x ²+ 14x + 8
-4x² + 6x + 8x + 3 + 5 + ? = 2x ²+ 14x + 8
-4x² + 14x + 8 + ? = 2x ²+ 14x + 8
? = 2x ²+ 14x + 8 + 4x² - 14x - 8
? = 6x²
In the second equation,
(-b³ + 3b² + 8) – (? - 562 - 9) = 5b³ + 8b² + 17
(-b³ + 3b² + 8) - (5b³ + 8b² + 17) = (? - 562 - 9)
? = -b³ - 5b³ + 3b² - 8b² + 8 - 17 + 571
? = -6b³ - 5b² + 562
Hence "The missing value in the first equation is 6x² while in the second it is -6b³ - 5b² + 562".

Use integers to represent the values in the statement.
The highest elevation in a country is a mountain, with an altitude of 14,240 feet. The lowest elevation in the country is a valley, with an altitude of 285 feet below sea level.
The integer represents the mountain's altitude, measured in feet.
Answer:
Highest Elevation: 14240
Lowest Elevation: -285
Step-by-step explanation:
Given
[tex]Highest\ Elevation = 14,240\ ft[/tex] above sea level
[tex]Lowest\ Elevation = 285\ ft[/tex] below sea level
Required
Represent both altitudes as an integer
For the Mountain:
Take the sea level as 0 feet
[tex]Altitude = Highest\ Elevation - Sea\ Level[/tex]
[tex]Altitude = 14240 - 0[/tex]
[tex]Altitude = 14240[/tex]
Hence, the integer is 14240
For the Valley:
Take the sea level as 0 feet
[tex]Altitude = Sea\ Level - Lowest\ Elevation[/tex]
[tex]Altitude = 0 - 285[/tex]
[tex]Altitude = -285[/tex]
Hence, the integer is -285
