Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{4}[/tex] x + 5 ⇒ m = [tex]\frac{1}{4}[/tex]
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]
y = [tex]\frac{1}{6}[/tex] x + 4 ⇒ m = [tex]\frac{1}{6}[/tex]
y = - [tex]\frac{1}{6}[/tex] x + 5 ⇒ m = - [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6}[/tex] x + 3 ⇒ m = [tex]\frac{1}{6}[/tex]
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{6}[/tex]
the 2nd and 4th lines are perpendicular

What do the zeros of this function represent? Remember the zeros are where f(x) =0.
Answers
We are given function for the path coming out of the cannon.
We also given x is the horizontal distance from the cannon.
We need to explain, what f(x) represents there.
f(x) represents y-axis.
And y-axis also represents height.
Height represents a vertical distance.
Therefore, we could say f(x) represents vertical distance (height) from the cannon for x horizontal distance from the cannon.

How many minutes are in 3 hours?
There are 60 minutes in one hour.
Complete the table.
Answers
Answer:
180
Step-by-step explanation:
because there are 60 minutes in an hour and you need 3 you need to add 60 + 60 + 60 or your can do 60 x 3 which equals 180
Answer:
180 minutes
Step-by-step explanation:
1 hour - 60 minutes
2 hours - 120 minutes
3 hours - 180 minutes
Because there is 60 minutes in an hour, you can do 60 x 3 = 180. This will directly tell us how many minutes are in 3 hours. Or, you can add 60 minutes 3 times for 3 hours.
So, 60 x 3 = 180. There are 180 minutes in 3 hours.

A ball is thrown from an initial height of 3 feet with an initial upward velocity of 44 ft/s. The ball's height h (in feet) after seconds is given by the following.
h = 3+44t-16t^2
Find all values of t which the balls height is 23 feet.
Answers
Answer:
See below ↓↓
Step-by-step explanation:
Given function
h = 3 + 44t - 16t²We need to calculate the possible values of t at h = 23 feet.
Subsituting h = 23,
23 = 3 + 44t - 16t²16t² - 44t + 20 = 0Divide throughout by 4 as it is a common factor4t² - 11t + 5 = 0Solving for 't' using quadratic formula
t = 11 ± √121 - 4(4)(5) / 8t = 11 ± √41 / 8Solutions
t = 11 + 6.4 / 8 = 17.4/8 = 2.175 secondst = 11 - 6.4 / 8 = 4.6/8 = 0.575 secondsAnswer:
t = 2.175 s (3 dp)
t = 0.575 s (3 dp)
Step-by-step explanation:
Given equation: [tex]h=3+44t-16t^2[/tex]
To find all values of t for which the ball's height is 23 ft, substitute h = 20 into the equation and solve for t:
[tex]\implies h=23[/tex]
[tex]\implies 3+44t-16t^2=23[/tex]
[tex]\implies 16t^2-44t-3+23=0[/tex]
[tex]\implies 16t^2-44t+20=0[/tex]
Factor out common term 4:
[tex]\implies 4(4t^2-11t+5)=0[/tex]
Divide both sides by 4:
[tex]\implies 4t^2-11t+5=0[/tex]
Quadratic formula
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0[/tex]
Use the quadratic formula to solve for t:
[tex]\implies t=\dfrac{-(-11) \pm \sqrt{(-11)^2-4(4)(5)} }{2(4)}[/tex]
[tex]\implies t=\dfrac{11 \pm \sqrt{41}}{8}[/tex]
Therefore,
t = 2.175 s (3 dp)t = 0.575 s (3 dp)If x²+ y²= 80 and xy = 12, find the value of (x - y)².

Answers
Answer:
p = 5/3m
Step-by-step explanation:
The Ratio of Pineapple juice to mango juice is 3:5. Since you can substitute the variable in, and they have already supplied part of the equation, you can set this equation up:
3p = 5m
divide both sides by 4
p = 5/3m
This tells us that for every cup of Pineapple juice, there is 5/3 cup of mango juice.

Find the area of the right triangle
Answers
Answer:
Formula for area of a triangle;
A = BH x 1/2
B = The base
H = The height
1/2 = Half of the product of (base x height)
We first need to figure out the base of this triangle, so count the units across from the base of this triangle.
The base is 4 units.
Now we need to find out the height, so count the units above starting from the base of this triangle and to the end of this triangle.
The height is 7 units.
Now plug these values into our equation:-
A = BH x 1/2
A = 4(7) x 1/2
A = 28 x 1/2
A = 28/2
A = 14, the area of this right triangle is 14 square units.
