Answer:
Below!
Step-by-step explanation:
The provided equation is in standard form. To convert it to slope intercept form, we need to have the y-variable isolated (as much as possible) on the L.H.S. Let's start the process by subtracting 6x both sides. This will isolate the y-variable and the cooeficient of the y-variable.
⇒ 6x + 2y = 12⇒ 6x - 6x + 2y = 12 - 6x⇒ 2y = 12 - 6xTo further isolate the "y" variable, let's divide 2 both sides. This will isolate the cooeficient of the y-variable. Once the cooeficient of the y-variable is fully isolated, we simply need to simplify the R.H.S (If needed). Then, the equation obtained is in slope intercept form.
⇒ 2y/2 = 12/2 - 6x/2⇒ y = 12/2 - 6x/2LIkewise, since the R.H.S can be simplified, let's simplify the R.H.S. The equation we obtained for now is in slope intercept form, but the simplified equation would help us to graph the line.
⇒ y = 12/2 - 6x/2⇒ y = 6 - 3xWhen we look at the slope intercept form formula (y = mx + b), we can see that "6" and "3x" needs to be switched.
⇒ y = -3x + 6 (Slope intercept form)Finally, lets plot the line on the graph. To plot the line on the graph, we need to determine the x-intercept and the y-intercept.
y-intercept: (0, 6)The x-intercept is the R.H.S of the equation we obtained. Keep in mind that the "y" variable will be 0.
⇒ -3x + 6 = 0Once we found the solution, we will determine two points of the line and lastly, we will plot the line on the graph.
⇒ -3x + 6 - 6 = 0 - 6⇒ -3x = -6⇒ -3x/-3 = -6/-3⇒ x = 2Thus, we obtained the following points:
x-intercept = 2 ⇒ Point obtained: (2, 0)y-intercept = 6 ⇒ Point obtained: (0, 6)→ Then, plot these points on the graph. Remember, x coordinate first.
→ Finally, we can draw a line through these points.
And we are done!
Graph:A town has a population of 90,200 and shrinks at a rate of 2% every year. Which equation represents the town’s population after 7 years
Answer: f(x) = 90,200 (1-.002)^7
Step-by-step explanation:
f(x) = a (1 - r)^t
a - initial amountr - ratet - timef(x) = 90,200 (1-.02)^7
The equation f(7) = 90,200 (1 - 0.02)⁷ represents the town’s population after 7 years.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
A town has a population of 90,200 and shrinks at a rate of 2% every year.
As we know the exponential equation for the population as
f(n) = a (1 - r)ⁿ
Where a is the initial population
r is rate
n is years
As per the question, we have
a = 90,200, r = 2/100 = 0.02, and t = 7 years
Substitute the known values in the above equation, and we get
f(7) = 90,200 (1 - 0.02)⁷
This equation represents the town’s population after 7 years.

The heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q=20930 joules (J) when m=1kg and T=5 degrees C. Find m when Q=8372 J and T=10 degrees C
Answer:
m = 0.2 kg.
Step-by-step explanation:
Joint variation:
Q = kmT where k is a constant.
Subsituting the given values:
20930 = k*1*5
k = 20930 / 5 = 4186.
So the relation is:
Q = 4186mT
When Q = 8372 and T = 10:
8372 = 4186 * m * 10
m = 8372 / (4186*10)
m = 0.2 kg.

In circle G with m \angle FGH= 86m∠FGH=86 and FG=16FG=16 units, find the length of arc FH. Round to the nearest hundredth.
The length of arc FH in the circle 8.37 units.
What is circle?In mathematics, a circle is a closed two-dimensional shape that consists of all the points in a plane that are a fixed distance (called the radius) from a given point (called the center). Circles are used in many areas of mathematics and science, including geometry, trigonometry, and physics. They have important applications in areas such as engineering, architecture, and computer graphics.
Here,
To find the length of arc FH, we first need to find the measure of angle FGH in degrees. Since the sum of angles in a triangle is 180 degrees, we can use the fact that angles FGH and FGF are supplementary to find:
m∠FGF = 180 - m∠FGH = 180 - 86 = 94 degrees
Since FGF is an inscribed angle that intercepts arc FH, the measure of arc FH is twice the measure of angle FGF. So we have:
m(arc FH) = 2 × m∠FGF = 2 × 94 = 188 degrees
To find the length of arc FH, we need to know the circumference of circle G. Since we know that FG = 16 units, we can use this to find the radius of the circle:
r = FG/2 = 16/2 = 8 units
The circumference of the circle is then:
C = 2πr = 2π(8) = 16π
To find the length of arc FH, we need to find the fraction of the circumference that arc FH represents, and then multiply this by the total circumference. Since the measure of arc FH is 188 degrees out of a total of 360 degrees in the circle, we have:
Length of arc FH = (188/360) × C
Substituting the value of C, we get:
Length of arc FH = (188/360) × 16π
Simplifying and rounding to the nearest hundredth, we get:
Length of arc FH ≈ 8.37 units

b) It takes 4 seconds before the weight is caught by the net.
What is the quadratic equation for a projectile's height?It is given by:
h(t) = -16t^2 + v(0)t + h(0).
In which:
v(0) is the initial velocity.h(0) is the initial height.Item a:
In this problem, the object starts from rest at a height of 67 ft, hence v(0) = 0 and h(0) = 67.
Then, the equation for the height is given by:
h(t) = -16t^2 + v(0)t + h(0)
h(t) = -16t^2 + 67
It hits the net when h(t) = 3, hence:
3 = -16t^2 + 67
16t² - 64 = 0.
Item b:
16t² = 64
[tex]t = \pm \sqrt{4}[/tex]
t = 4, as time is positive.
