Step-by-step explanation:
a function is when each x has a y
a relation is when 1 x has more than 1 y which makes it invalid therefore not a function

Hm. If p is true, then q is true, if p is false, than q is false.
So, the inverse must be true.
The converse doesn't have to be true at all, and same with the contrapositive if I'm correct.
Pretty sure it's just the inverse. :)

Domino's can make 4 pizzas using 3 1/2 cups of sauce. How many cups of sauce are needed to make 1
pizza?
7/8 cups of sauce are needed to make 1 pizza.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Domino's can make 4 pizzas using 3 1/2 cups of sauce.
Now, for 1 pizza he needed
= (3 1/2) /4
= (7/2)/ 4
= 7/2 x 1/4
= 7/8 cups of sauce.
Hence, 7/8 cups of sauce needed.

Answer:
The answer is 5.8 kmStep-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side c
Using Pythagoras theorem we have
c² = b² + a²
where
c is the hypotenuse
So we have
[tex] {c}^{2} = {5}^{2} + {3}^{2} \\ c = \sqrt{ {5}^{2} + {3}^{2} } \\ c = \sqrt{ 25 + 9} \\ c = \sqrt{34} \: \: \: \: \: \: \: \: \\ = 5.83095189...[/tex]

$27,200 at 9% compounded annually for 2 years
Answer:
A = $32316.30
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
Principal amount P = 27200
Rate r = 9% or 0.09
Number of years n = 2 years
Step 2: Substitute and Evaluate for A
A = 27200(1 + 0.09)²
A = 27200(1.09)²
A = 27200(1.1881)
A = 32316.30

Solve for x. 7 + 11x + 60 = -13 + 3x
Answer:
x = -10
Step-by-step explanation:
Step 1: Write equation
7 + 11x + 60 = -13 + 3x
Step 2: Solve for x
Combine like terms: 11x + 67 = -13 + 3xSubtract 3x on both sides: 8x + 67 = -13Subtract 67 on both sides: 8x = -80Divide both sides by 8: x = -10Step 3: Check
Plug in x to verify it's a solution.
7 + 11(-10) + 60 = -13 + 3(-10)
67 - 110 = -13 - 30

What is the y-intercept of the function below? Y=4x+4 (15 Points!)
Answer:
y- intercept = 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 4 ← is in slope- intercept form
with y- intercept c = 4
solve for x
(x/r)+(x/w)+(x/t)= 1
x/r + x/w + x/t = 1
x (1/r + 1/w + 1/t) = 1
x = 1 / (1/r + 1/w + 1/t)
To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, rwt :
x = 1 / (1/r + 1/w + 1/t) • rwt / rwt
x = rwt / (rwt/r + rwt/w + rwt/t)
x = rwt / (wt + rt + rw)
A car travels 32 km due north and then 46 km in a direction 40 degrees west of north. Find the magnitude of the cars resultant vector nearest tenth
Answer:
Step-by-step explanation:
In order to find the magnitude of the car's final displacement (resultant displacement vector), we need the x and y components of each part of the car's journey. We will call them vector A and vector B. The info for the vectors is as follows:
A: magnitude 32 at an angle of 90.0
B: magnitude 46 at an angle of 40.0
The x components are found in the formula
A(x) = magA*cos(angle)
For A(x):
A(x) : 32cos(90.0) = 0.0 and
For B(x) : 46cos(40.0) = 35.2
For A(y): 32sin(90.0) = 32 and
For B(y): 46sin(40.0) = 3.0 × 10¹
To get the x components of the final vector, add the x components of A and B together:
C(x) : 0.0
35.2
35.2
To get the y components of the final vector, add the y components of A and B together:
C(y) : 32
30
62
Now to get the magnitude, throw it into the magnitude formula, which is identical to Pythagorean's theorem:
C(mag) = [tex]\sqrt{(35.2^2)+(62^2)}=71.3 km[/tex]

John throws a ball upward at a rate of 22 meters per second from an
initial height of 3 meters. The height of the ball above the ground can
be approximated by h (t) = -16t2 + 22.0 + 3, where t represents
the amount of time, in seconds, since the ball has been released.
How many seconds will it reach the ground?
Answer:
1.5 seconds
Step-by-step explanation:
The height equation is supposed to be ...
h(t) = -16t^2 +22t +3
We want to find the positive value of t where h(t) = 0.
0 = -16t^2 +24t -2t +3 . . . . facilitate factoring
0 = -8t(2t -3) -1(2t -3) . . . . . factor by pairs
0 = -(8t +1)(2t -3) . . . . . . . . complete the factoring
The solutions to this are ...
t = -1/8, 3/2
The ball will reach the ground in 1.5 seconds.
