Answer:

Step-by-step explanation:

[ -t² + 5t² - 6t] + [8t² - 8t] = -t² + 5t² - 6t + 8t² - 8t

{bring the like terms together}

= -t² + 5t² + 8t² - 6t - 8t {add/subtract the like terms}

= 12t² - 14t

mariarad [96]

Answer:

The next three terms for each are: a) 123, 146, 171; b) 47,51,55; c) 10000,10001, 10010; d)8,8,8; f)654729075,13749310575,316234142225; g)0,0,0

Step-by-step explanation:

In a) the last number +(2i+1) in which i is the number of terms=1,2,3...

b) n+4, for any last number, you add 4

c) 1,0 and the same is repeated for the next decimal

d) n=sum of 2 previous different numbers. The frequency is given by 2i-1 in which is is the number of terms i=1,2,3...

e) missing

f) ni+1=n*(2i-1) in which ni+1 is the resulting number, n is the previous number and i is the number of terms=1,2,3...

g) it is 1 for odd numbers and 0 for even numbers. The frequency is given by i+1, in which the number of terms i= 0,1,2,3...

Conference A and conference B each have 10 football teams. The table shows the number of football games that each team in the tw

babymother [125]

Answer with explanation:

1.Mean of a Data set

$=\frac{\text{Sum of all the observation}}{\text{total number of observation}}$

$=\frac{10+9+11+8+10+12+2+7+8+0+12+10+8+11+3+12+6+7+4+3}{20}\\\\=\frac{153}{20}\\\\=7.65$

2. Range = Maximum value in two conferences - Minimum value in two conference

= 12 - 0

=12

The mean number of wins for teams from the two conferences is 7.65.

The range in wins is 12.

Suppose you are given a parabola with two points that have the same y-value, such as (-7, 11) and (3, 11). Explain how to find t

Hoochie [10]

By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.

<h3>How to derive the equation of the axis of symmetry </h3>

In this question we know the locations of two points with the same y-value, which means that the axis of symmetry is parallel to the y-axis and that both points are equidistant. Thus, the axis of symmetry passes through the midpoint of the line segment whose ends are those points.

First, calculate the coordinates of the midpoint by the midpoint formula:

M(x, y) = 0.5 · (- 7, 11) + 0.5 · (3, 11)

M(x, y) = (- 2, 11)

Second, look for the first coordinate of the midpoint and derive the equation of the line associated with the axis of symmetry:

x = - 2

By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.
