Answer: n squared - 1
Step-by-step explanation:
The relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.
What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is a pattern of small squares as described -
Step 1 has 0 squares.
Step 2 has 3 squares : 2 by 2 but missing the lower right square.
Step 3 has 8 squares : 3 by 3 but missing the lower right square.
We can write the general expression for step {n} as -
Step {n} will have : 2ⁿ - 1 squares with missing the lower right square.
or
f(n) = 2ⁿ - 1
Therefore, the relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.

Joe designs a weighted number generator that produces the integers 0 to 4. He then run the generator 500 times. The results are shown in the table. If Joe runs a generator a total of 4000 times, which is the closest to the expected number of times to integer for is produced?
Answer: since there is no table shown you can’t really tell but the closest would be the number that shows up the most amount of time but you would have to take into consideration of the increase of the number

Answer:
$32.60
Step-by-step explanation:
Remember to find the percentage of something, times the number by the percentage, which is two decimals to the left. So 15% would be 0.15.
The total is unknown so replace it with a variable, such as x
.15(x)=4.89
Isolate x by dividing both sides by 0.15
x=32.6
Meal price: $32.60
Check your answer by multiplying this number by the tip percentages
32.6(.18)=5.87
32.6(.20)= 6.52

6x^2+3x+24=0 solve by factoring
Answer:
No real solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+3x+24=0
For this equation: a=6, b=3, c=24
6x2+3x+24=0
Step 1: Use quadratic formula with a=6, b=3, c=24.
x= (−b±√b2−4ac) /2a
x=( −(3)±√(3)2−4(6)(24))/ 2(6)
x= (−3±√−567) /12

2. Dwayne scored 55 points in the last basketball game, which is 10 points more than his previous personal best. Lebron scored 15 points more than Chris in the
same game. Lebron scored the same number of points as Dwayne’s previous personal best.
Write two algebraic equations, let d represent the number of points Dwayne scored during his previous personal best and c represent the number of Chris’s points.
Answer:
Required equations are:
d + 10 = 55c + 15 = dSolving the first, we get:
d = 55 - 10d = 45Solving the second we get:
c + 15 = 45c = 45 - 15c = 30Which is larger, a pound or a kilogram? Explain your reasoning.

A ring-shaped region is shown below. Its inner radius is 19 m, and its outer radius is 24 m. Find the area of the shaded region. Use 3.14 for . Do not round your answer.
Answer:
675.1 sq m
Step-by-step explanation:
Area of larger circle = 3.14(24^2) = 3.14(576) = 1808.64
area of smaller circle = 3.14(19^2) = 3.14(361) = 1133.54
area of ring = Area of larger circle - area of smaller circle
= 1808.64 - 1133.54 = 675.1

Find the average rate of change of g(x) =-x²+2x+2 from x=2 to x = 6.
Simplify your answer as much as possible.
Solve the equation replacing x with 2 and the 6:
-2^2 + 2(2) + 2 = 4 + 4 + 2 =10
-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50
Difference between the answers: 50-10 = 40
Difference between 2 and 6 = 6-2 = 4
Average rate of change = 40/4 = 10
The answer is 10
