The expression. 3(5^2 +2x+4)-4(4x^2 +2x+3) equals?

Answer:

89,86,83

Step-by-step explanation:

92-80=12

12÷4=3

80+3=83

83+3=86

86+3=89

The complete arithmetic sequence will be: 92, 89, 86, 83, and 80.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as;

aₙ = a₁ + (n - 1)d

Given; The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as;

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12

92, 89, 86, 83, and 80

Hence, the complete arithmetic sequence will be: 92, 89, 86, 83, and 80.

(2x + 1)

___↑___

A — B — C

|____|___|

↓ ↓

(x + 4) (2x – 10)

_______________________________

When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.

Thus:

(x + 4) + (2x – 10) = (2x + 1)

[Regroup terms]

(x + 2x) + (4 – 10) = (2x + 1)

[Simplify]

(3x – 6) = (2x + 1)

[subtract 2x from both sides to isolate the variable]

(3x – 6) – 2x = (2x + 1) – 2x

[Regroup terms]

(3x – 2x) – 6 = (2x – 2x) + 1

x – 6 = 1

[Add 6 to both sides to isolate the constant]

x – 6 + 6 = 1 + 6

[Simplify]

x = 7

Answer:

W = 1.06 MJ

Step-by-step explanation:

- We will use differential calculus to solve this problem.

- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.

- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Answer:

19e

Step-by-step explanation:

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]

Given that:

[tex]f(x) = 2(x - 2)^2 - 8[/tex]

To identify the true statement, I will make use of graphical method.

See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]

From the attached graph, we can see that the graph as a minimum at:

[tex](x,y) = (2,-8)[/tex]

And it opens upward.

This implies that the minimum y-value of f(x) is at -8, and it has no maximum.

In other words, the range of the function is:

[tex]f(x) \ge -8[/tex]

Hence, the true statement is option (a):

The range of f(x) is [tex]y \ge -8[/tex]

Answer:

  E

Step-by-step explanation:

You can see from the first and last points that the data set demonstrates a slight upward trend. That means the slope of the regression line will be near +1, eliminating all choices except A and E.

The y-intercept of such a line will not be negative, eliminating choice A, leaving choice E as the only reasonable option.

If you input this data to a suitable calculator or spreadsheet, it can find the parameters of the regression line for you. (We presume you have been introduced to such tools.) My graphing calculator gave the results shown below, confirming E is the correct choice.

Mean of total 5 digits is 18.6

Given:

Mean of first 3 digit = 19

Mean of next 2 digit = 18

Find:

Mean of total 5 digits

Computation:

Sum of first 3 digit = Mean of first 3 digit × Number of digits

Sum of first 3 digit = 19 × 3

Sum of first 3 digit = 57

Sum of next 2 digit = Mean of first 3 digit × Number of digits

Sum of next 2 digit = 18 × 2

Sum of next 2 digit = 36

Total of 5 digit = Sum of first 3 digit + Sum of next 2 digit

Total of 5 digit = 57 + 36

Total of 5 digit = 93

Mean of total 5 digits = Total of 5 digit / 5

Mean of total 5 digits = 93 / 5

Mean of total 5 digits = 18.6
