If a polygon has exactly 4 sides, it is a quadrilateral. State the contrapositive of the conditional statement. A) If a polygon is a quadrilateral, it has exactly 4 sides. B) If a polygon is a quadrilateral, it does not have exactly 4 sides. C) If a polygon is not a quadrilateral, it does not have exactly 4 sides. D) If a polygon does not have exactly 4 sides, it is not a quadrilateral.
Answer: I think the answer is D
Step-by-step explanation:
Option - C is the correct option.
We have a statement - If a polygon has exactly 4 sides, it is a quadrilateral.
We have to write the contrapositive of this conditional statement.
What do you mean by Contrapositive of the Conditional statement ?A combination of the converse and the inverse is called Contrapositive of the Conditional statement. Contrapositive will replace if with then and vice - versa and after that both parts are negated.
According to the question, we have a statement -
If a polygon has exactly 4 sides, it is a quadrilateral.
Firstly, replace ' if ' with ' they ' and vice - versa. We get -
If a polygon is a quadrilateral, than it does have exactly four sides.
Now, negate it -
If a polygon is not a quadrilateral, it does not have exactly 4 sides.
Hence, Option C is correct.

.Ray's Rental Car Company charges a $50 rental fee, $15 for gas and $0.25 per mile driven. For the same car, Rosie's Rental Car Company charges $40
for rental and gas and $0.35 per mile driven. At what mile do the companies charge the same amount?
Answer: 166.667 miles
Step-by-step explanation:
For the first company, the cost can represented by the equation: y=0.25m +50+15
Which is the same as y=0.25m +65
For the second company, the cost can represented by the equation:0.35m+40
m is the miles driven
To find at after how many miles they cost the same, I will set both equations equal to each other to solve for m
0.25m+65=0.35m+40
-0.25m -0.25m
65=0.15m+40
-40 -40
25=0.15m. Divide both sides by 0.15
166.667=m
So after 166.667 miles, the companies charge the same.
You can also round it again: 166.67 or 166.7 or 167
Given the definitions of f(x) and g(x) below, find the value of g(f(-3)).
Answer:
-11
Step-by-step explanation:
f(x) = 5x + 11
g(x) = x^2 + 4x - 11
g(f(-3)) = ?
f(-3) = 5(-3) + 11
= -15 + 11 = -4
g(f(-3)) = g(-4) = -(4)^2 + 4(-4) - 11
= 16 - 16 - 11 = -11
A function assigns the value of each element of one set to the other specific element of another set. The value of g(f(-3)) is -11.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=5x+11 and g(x)=x²+4x-11, therefore, we can write the value of g(f(x)) as,
g(f(x)) = (5x + 11)² + 4(5x + 11) - 11
= 25x² + 121 + 110x + 20x + 44 - 11
= 25x² + 130x + 154
Now, substitute the value of x as -3 in the function g(f(x)), therefore, we can write,
g(f(-3)) = 25x² + 130x + 154
= 25(3)² + 130(-3) + 154
= 225 - 390 + 154
= -11
Hence, the value of g(f(-3)) is -11.

A publisher sells 10⁶ copies of a new book. Each book sells 10² pages. How many pages total are there in all of the books sold? Write the answer using exponents.
1 point
Answer:
10^12.
Step-by-step explanation:
You need to solve 10^6 * 10^2 without using standard notation. As with variables, if you had x^6 * x^2 you would add the exponents. Replace x with 10. Your answer is 10^8. As a sidenote, only multiply exponents when raising a power to another power, e.g. (10^6)^2 = 10^12.

0.1 + 0.2x +0.3 + 0.05x = -2.4
Answer:
x = -11.2
Step-by-step explanation:
0.1 + 0.2x + 0.3 + 0.05x = -2.4
Combine like terms on the left side.
0.25x + 0.4 = -2.4
Subtract 0.4 from both sides.
0.25x = -2.8
Divide both sides by 0.25.
x = -11.2

2. Which relations represent a function? Check all that apply.
If you wanna help with the bottom two that would be very helpful too!!
Answer:
for the top its the first one
Step-by-step explanation:
a function is when a number has one corresponding number (some say exponent or other words)
A relation may or may not represent a function
The relations that represent a function are: (a) first ordered pair and (c) the linear graph
For an ordered pair to be a function, each x values must not point to several y-values
For a graph to represent a function, it must pass the vertical line test.
Based on the above highlights, the relations that represent a function are:
(a) first ordered pair- because all y values point to different x values(c) the linear graph - because it passes the vertical line testRead more about relations and functions at:
