In an expression when should be completed addition or multiplication

Answer:

Not a linear relationship

Step-by-step explanation:

Given

The attached table

Required

Linear or not

To do this, we simply calculate the slope of the table at different intervals.

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (0.5,7.2)[/tex]

So, the slope is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{7.2 - 0}{0.5-0}[/tex]

[tex]m = \frac{7.2}{0.5}[/tex]

[tex]m = 14.4[/tex]

Let:

Let:

[tex](x_1,y_1) = (1,10.7)[/tex]

[tex](x_2,y_2) = (2,12.2)[/tex]

So, the slope is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{12.2 - 10.7}{2 - 1}[/tex]

[tex]m = \frac{1.5}{1}[/tex]

[tex]m = 1.5\\[/tex]

See that the calculated slopes are not equal.

Hence, it is not linear

Answer:

17

Step-by-step explanation:

15^2 + 8^2 = 225 + 64 = 289

=17

Answer:

36 cm^2 is the area

Explanation -->

- first, separate the polygon into two separate ones, horizontally, to make two rectangles

- NOTE : Area = length x width

- 6 times 4 = 24

- 4 times 3 = 12  (self-explanatory, you get 4 by subtracting 6 and 2, as you can see)

- 24 + 12 = 36

-- You get 36 cm^2 --

Answer:

m(minor arc KL) = 153°

Step-by-step explanation:

"Measure of intercepted arcs between two diameters are equal in measure"

By this property,

m(JK) = m(HL)

(7x - 1)° = (5x + 7)°

7x - 5x = 7 + 1

2x = 8

x = 4

Therefore, m(arc HL) = (5x + 7)

                                  = 5(4) + 7

                                  = 27°

Now measure of minor arc KL = m(arc KH) - m(arc HL)

                                                  = 180° - 27°

                                                  = 153°

Therefore, measure of minor arc KL is 153°

Answer:

Yield on this bond = 4.5%

Step-by-step explanation:

Given:

Face value of bond = $10,000

Annual interest receives from bond = $450

Find:

Yield on this bond

Computation:

Yield on bond = [Annual interest / Face value]100

Yield on this bond = [Annual interest receives from bond / Face value of bond]100

Yield on this bond = [450 / 10,000]100

Yield on this bond = [0.045]100

Yield on this bond = 4.5%

Answer:

  (a)  c = 4

  (b)  c < 4

  (c)  c > 4

Step-by-step explanation:

(a) The solutions to the system of equations can be found by substituting one expression for y into the other equation:

  3x^2 -5x = 2x^2 -x -c

  x^2 -4x +c = 0 . . . . . . . subtract the right side expression

The discriminant is

  d = b^2-4ac = (4)^2 -4(1)(c) = 16-4c.

The system will have exactly one solution when d = 0.

  16 -4c = 0

  4 -c = 0

__

(b) There will be more than one real solution when d > 0

  4 -c > 0

  c < 4 . . . . two real solutions

__

(c) There will be no real solutions when d < 0.

  4 -c < 0

  c > 4 . . . . no real solutions

Additional comment

The question posed here simply asks for a value of c. It does not ask for the solutions (x, y). We can count them without knowing exactly what they are.

Answer:

B 84 is our answer

Step-by-step explanation:

triangle formula for surface area is base x height divided by 2 so 7 x 6 = 42 42 ÷ 2 = 21 All the other triangles are going to be the same so 21 x 4 = 84 so 84 is our surface area

i hate these questions lol her name do be karen sorry um you do multiplicaton for this question i hate aleks expesially thqat question i feel you bro

Step-by-step explanation:

Answer: it’s all in the explanation!

Step-by-step explanation:

So, in the question, it states that she’s gunna have two tables for every six guests. You’re gonna need to find out how much people are going to be at ONE table, so two divided by six! And as you know, that equals three. For the first space, since it’s a odd number, you need to use the three instead of six since there’s gunna be one table by itself. So three times 5. The first space is gunna be 15 :). The second space is somewhat the same process. What times three equals 21? Seven! So for the second space, you’re gunna pit seven. For the third one, you do 8 times three, which equals 24. And for the last space, it’s 10, for three times ten :), hoped this helped!

For a gestation period of 6 months, the life span is 15.

Step-by-step explanation:

Gestation(months)   x        8     2.1    1.3     1    11.5    5.3   3.8    24.3

Life span (years)       y       30    12      6      3   25      12    10     40

y =?   x= 6 months

Assuming the variables x and y have a significant correlation

Answer:

4.67 feet

Step-by-step explanation:

The computation of missing dimension of the triangle is given below:

As we know that

Area of the triangle = 1 ÷ 2 × base × height

14 = 1 ÷ 2 × base × 6

14 = 3 × base

So, the base is

= 14 ÷ 3

= 4.67 feet

Here we assume the area to be 14 square feet

Answer:

4⅔ or 4.67 feet

Step-by-step explanation:

Area of a triangle is ½bh

½×b×6=14

3b=14

14÷3=4⅔
