Answer:

Step-by-step explanation:
The function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}
What is a function ?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
According to the graph
When x < 3 then y = + 6
and, at x = 3 we get an open interval.
So, y = x² + 6 is valid for x < 3 not at x =3.
Also , y = -x + 6 is valid for x ≥ 3 and we get a close interval.
Thus, the function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}

The car you are taking is reliable and in good condition. The insurance is paid, the maintenance is up to date, and it gets about 27 miles to the gallon. The gas tank holds 18.5 gallons, and the low gas light will turn on when there are 2.5 gallons left in the tank. You have saved up $1,264
to spend on these trips. You must get gas if your low gas light turns on. The average gas price in

What is the Distance Between Two Points?On a coordinate plane, the distance between two points is the number of units in between the two points lying on the same axis.
Let's find the distance between (6, -2) and eaxh of the given endpoints tro know which gives us a length of 4 units.
(6, -2) and (6, 2) = |-2 - 2| = 4 units
(6, -2) and (6, 6) = |-2 - 6| = 8 units
(6, -2) and (10, -2) = |10 - 6| = 4 units
(6, -2) and (2, -2) = |6 - 2| = 4 units
(6, -2) and (6, -6) = |-2 - (-6)| = 4 units
(6, -2) and (-2, -2) = |6 - (-2)| = 8 units
(6, -2) and (-10, -2) = |6 - (-10)| = 16 units
Therefore, the possible coordinates of the other endpoint of the line are: (6, 2), (10, -2), (2, -2), and (6, -6).

write the equation of a line in slope interest form that passes through (16,0) and (17,12)
Answer:
y=12x - 192
Step-by-step explanation:
Hi there!
We are given the points (16,0) and (17, 12)
We want to write the equation of the line that contains these points in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
First, we need to find the slope
The slope (m) can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have 2 points, which is what we need to find the slope, but let's label their values to help avoid confusion and mistakes
[tex]x_1=16\\y_1=0\\x_2=17\\y_2=12[/tex]
Now let's plug these values into the formula to find the slope
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{12-0}{17-16}[/tex]
Subtract
m=[tex]\frac{12}{1}[/tex]
Divide
m = 12
The slope of the line is 12.
Let's substitute that as m in y=mx+b.
Here is our equation so far:
y=12x + b
Now we need to find b
As the equation passes through the points (16,0) and (17, 12), we can use either one of them to solve for b.
Using (16,0) for example:
Substitute 16 as x and 0 as y.
0 = 12(16) + b
Multiply
0 = 192 + b
Subtract 192 from both sides
-192 = b
Substitute -192 as b in the equation
y = 12x - 192
Hope this helps!

The diameter of the cone is 6 inches. It’s height is 4 inches. What is its slant height?
Answer:
5 inches
Step-by-step explanation:
As the height is perpendicular to the base, the radius and the height form a right angle, creating a right triangle where the slant height is the hypotenuse, thus:
[tex](height)^2+(radius)^2=(slant\:height)^2[/tex]
[tex]4^2+(6/2)^2=(slant\:height)^2[/tex]
[tex]16+9=(slant\:height)^2[/tex]
[tex]25=(slant\: height)^2[/tex]
[tex]5=slant\: height[/tex]
In conclusion, the slant height of the cone is 5 inches. See below for a visual.
