Answer:
Option A
Step-by-step explanation:
ok so firstly this is super duper easy! all you have to see first in these type of questions is the "sequence" or the "pattern". and you have to make a ittle equation with this, so the first picture has 1 square, secound one has 5, the third one has 9, and the fourth one has 13.
- so firstly see or find a specific sequence.
13 - 9 = 4
9 - 5 = 4
5 - 1 = 4
so we found out "4" is the main changing unit. Now lets make a short formula which will help us determine any number ahead of the picture.
so lets do 4x = number of squares, x= figure number
4(1) = 4 :: wrong, because the first figure has only one square
so, 4x - 3
4(1) - 3 = 1 :: correct! this euqation works!
Now, we need to find how many squared there are in figure 100, so ->
4(100) - 3 = 397 squares!
and now doing the question will be easier, because option A says 1 square in the centre and 99 sqaures on each side.
So-> 99 + 99 + 99 + 99 +1 = 397! boom!! got the answer!

Based on the data provided by Connor, the correlation coefficient of the relationship is -0.84.
What is the correlation coefficient?
Correlation is used to determine the type of relationship that exists between two variables.
A negative correlation is when the two variables move in opposite directions. If one variable increases, the other variable decreases. A negative correlation has a negative sign in front of it.
The correlation coeffcieenct can be determined using a financial calculator.

-19x/-19 = -133/-19
-19 cross with -19 leaving x, negative cross with negative leaving 133/19

Use the table below to write an equation in slope intercept form. How did you find the slope and the y intercept of the equation?
Answers
Answer:
y = 8x+9
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( 57-17)/(6-1)
= 40/5
= 8
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = 8x+b
Substitute a point into the equation
33 = 8*3 +b
33 = 24+b
Subtract 24 from each side
33-24 = 24+b-b
9 = b
y = 8x+9
#equation
(1,7)(3,33)Slope
m=33-17/3-1m=16/2m=8.Now
y-y_1=m(x-x_1)y-17=8(x-1)y-17=8x-8y=8x+9On comparing to slope intercept form
y intercept is 9

D) [tex](-2,-9)[/tex]
Step-by-step explanation:
Vertex Form of a Vertical Parabola:
[tex]y=a(x-h)^2+k[/tex]
Vertex -> [tex](h,k)[/tex]
Axis of Symmetry -> [tex]x=h[/tex]
Vertical Scale Factor -> [tex]a[/tex]
To turn [tex]f(x)=x^2+4x-5[/tex] into vertex form, we need to complete the square on the right sideTherefore, if [tex]f(x)=0[/tex], then [tex]0+9=x^2+4x-5+9[/tex] completes the square on the right side This becomes [tex]9=(x+2)^2[/tex]This means that our function in vertex form is [tex]f(x)=(x+2)^2-9[/tex]Therefore, the vertex of the graph is [tex](h,k)=(-2,-9)[/tex].
The coordinates of the vertex of the graph is (-2, -9).
What are Quadratic Functions?Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.
The general form of a quadratic function is f(x) = ax² + b x + c.
Given is a quadratic function,
x² + 4x - 5
Given that axis of symmetry of the function is x = -2.
So the x coordinate of the vertex = -2.
y coordinates = f(-2) = 4 - 8 - 5 = -9
Hence the vertex is (-2, -9).

A: Wrong. The first statement is wrong. m is the dependent variable. Time is usually the independent variable as it is in this case.
B: True. That happens
C: True. Miles increases as time increases.
D: True. If h is hours then H is the independent Variable
E: is wrong. H cannot be both, and it is not the dependent variable
