Imagine there are 8 spots on the shelf. Replace the volumes one by one.
The first volume to be replaced could go in any one of the eight spots.
The second volume to be replaced could then go in any one of the seven remaining spots.
The third volume to be replaced could then go in any one of the six remaining spots.
etc
So the total number of ways the eight volumes could be replaced
= 8!
= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 40,320
So the vertex formula is A(X - H)^2 + K so find the vertex and plug all numbers in
this gives you (x - 2.5)^2 -3.25 = f(x)
Answer:
Step-by-step explanation: We would solve this exactly like we would a variable equation. If it makes it easier imagine there is equal sign instead of a inequality sign.
First we add 4 to both sides.
6<-5t-4
10<-5t
Then we divide both sides by -5.
10<-5t
10/-5<-5t/-5
The two -5s cancel out only leaving the 10 to be divided by the -5......
but a law in math tells us if we divide in math by a negative or multiply by one then we must reverse the inequality sign.
.....which leaves us with the answer.
-2>t
Hope this helps!
The length and width of Jessica's kitchen table would be= 4.5ft
<h3>What is perimeter?</h3>
Perimeter is defined as the summation of all the sides of an object or a field.
The perimeter of a kitchen table with four would be 4 × a. where a represents the sides.
The area of the kitchen table = 18ft²
The perimeter of the kitchen table = 18ft
The length and width of the kitchen table can be calculated from the perimeter;
18/4 = 4.5
The length and the width of a square kitchen table should be the same Value= 4.5ft.
