Answer:1) 2n - 1
2) 99
see in the picture, u can see that the number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
......
=> The above sequence has: u1 = 1
d = 2
=> u(n) = 1 + 2(n - 1) = 2n - 1
=> the number of shaded squares in the n figure is 2n - 1
b) the number of shaded squares in the 50th figure is 2.50 - 1 = 99
Step-by-step explanation:
a) The number of shaded squares in the n figure is 2n - 1.
b) The number of shaded squares in the 50th figure is 99.
What is the number pattern?A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
The number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
The above sequence has: u1 = 1, d = 2
u(n) = 1 + 2(n - 1) = 2n - 1
The number of shaded squares in the n figure is 2n - 1.
b) The number of shaded squares in the 50th figure
2.50 - 1 = 99

A. 0 and 4
B. -4, -2 and 0
C. 0, 2, and 4
D. -4 and 0
Answers
Answer:
Option C
Step-by-step explanation:
Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.
In the image we see the graph intersects the x-axis at three points
x=0 , x=2 , x=4 so our answer is option C
The roots or zeros of the graphed function f(x) are 0, 2 and 4.
What are the zeros of a function?
The x - intercepts of the graph of the function gives the zeros of the function. It is at this value that the dependent variable [y] is zero.
Given is a graph of a function f(x).
The graph of the function f(x) is shown. The total number number of x - intercepts will tell us about the degree of the function which is equal to three. The degree of a function also represents the total number of possible solutions or zeros of the function and the values of the x - intercepts will be the zeros of the function. The graph of the function cuts the x - axis at x = 0, x = 2 and x = 4.
So, we can conclude that the graph has a degree of 3 and the possible roots or zeros of this function f(x) are x = 0, x = 2 and x = 4 repsectively.
Therefore, the roots or zeros of the graphed function are 0, 2 and 4.

Answer: Choice 4) AC is four times longer than DF
=========================================================
Explanation:
Let's say AC is 4 units long. This makes AE half as long because AE is a radius of the larger circle and AC is the diameter of that same larger circle. So we know AE = 2. Segment DE is also a radius of that circle. So AE = DE = 2.
Segment DF is half as long as DE, leading to DF = DE/2 = 2/2 = 1.
We have DF = 1 and AC = 4. This shows AC is four times longer than DF.
--------------
Put another way:
AC = 2*(AE)
AC = 2*(DE)
AC = 2*(2*DF)
AC = (2*2)*DF
AC = 4*DF
So AC is four times longer than DF. We can replace DE with 2*DF since the diameter DE is twice as long compared the radius DF (for the smaller circle).

Mr. and Mrs ------ Have a number of children. if 0.83 of the childern are male, what is the least possible number of people in the ------ family?
Answers
Answer:
The least possible number of people in the family is 8.
Step-by-step explanation:
To determine the minimum number of people that make up the family, knowing that 0.83 of the children are boys, the following logical reasoning must be carried out:
Given that 0.83 is the result of 5/6, it can be said that 5 of the 6 children of the couple are boys. These 6 children must be added to the 2 fathers of the family, with which the total number of family members is 8.
