A
–7 – i ohms

B
–7 + i ohms

C
–7i ohms

D
7 + i ohms

Answer:

- 22.667

Step-by-step explanation:

1.5^3 = 1.5 x 1.5 x 1.5 = 3.375

- 3.64 ⋅ | 5.3 | - 1.5^3

= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3

= ( - 3.64 ⋅ 5.3 ) - 1.5^3

= ( - 3.64 x 5.3 ) - 1.5^3

= - 19.292 - 3.375

= - 22.667

F) 0.00125 kg

G) 3900 kg

H) 2 kg

I) 5000 g

J) 3.6 kg

Answer:

Step-by-step explanation:

9.

Area = 15 × 5

Area = 75

perimeter = 15 + 6 + 15 + 6 = 42

10.

Area = (10 × 15) ÷ 2 = 75

perimeter = 18 + 10 + 15 = 43

11.

Area = (25 × 10) ÷ 2 = 125

perimeter = 31.6 + 25 + 11.2 = 67.8

Step-by-step explanation:

10.30×5=51.50

8.99×3=26.97

51.50+26.97+29.99=108.46

108.46+6.7%

108.46+7.27=115.73

The probability of randomly selecting an insect is 2/15.

It is a measure of happening or non happening of the outcomes of a random experiment.

P(E) = number of favorable outcomes/Total number of outcomes

Where, P(E) is the probability of any event.

Let E be an event of selecting an insect.

According to the given question

We have

Total number of insects = 10

Total number of trees = 8

Total number of flowers = 8

Total number of birds = 4

Now, the total number of outcomes = 10 + 8 + 8 + 4 = 30

Total number of favorable outcomes = 4

Therefore,

The probability of selecting an insect = [tex]\frac{4}{30} =\frac{2}{15}[/tex]

Answer

Step-by-step explanation:

So since m<6 = 62, we can tell that m<2 is also 62. since the angles add up to 180, 180-62=118. so m<1 = 118. m<4 = 62.

Answer:

(5,-12)

(-3,0)

(-1,-1)

Step-by-step explanation:

For (4, −12): 2(4) - 12 = 8 - 12 = -4                  [false]

For (−3, 0): 2(-3) = -6 < -4                                [false]

For (5, −12): 2(5) - 12 = 10 - 12 = -2 > -4         [true]

For (0, 1): 2(0) + 1 = 1 > -4                              [true]

For (−1, −1): 2(-1) - 1 = -2 - 1 = -3 > -4            [true]

Therefore, (5, -12), (0, 1) and (-1, -1) satisfies the inequality 2x + y > -4

For (7, 12): 12 - 2(7) = 12 - 14 = -2 > -3                   [false]

For (0, −2): -2 - 2(0) = -2 > -3                                   [false]

For (5, −3): -3 - 2(5) = -3 - 10 = -13 < -3                   [true]

For (−6, −3): -3 - 2(-6) = -3 + 12 = 9 > -3                  [false]

For (1, −1): -1 - 2(1) = -1 - 2 = -3                              [true]

Therefore, (5, -3) and (1, -1) satisfy the inequality y - 2x ≤ -3

The situation is represented by 2.25x + 2.65y ≥ 8

step 1, c

Step-by-step explanation:

he was wrong in step 1.

when factoring out (x-4) and (x-2), you have to distribute x*x, x*-2, -4*x, and -4*-2

if you do it you get x^2 - 2x -4x + 8

the correct way to factor will be (x-4)(x+2)

when you factor out you will get the original equation you started with.

Answer:

From 1st eqn .,

3x=4+5y

X=4+5y/3

From 2nd eqn ..,

-2x+6y=18

-2(4+5y/3)+6y=18

-8+10y/3 +6y=18

-8+10y+18y/3=18

-8+28y/3=18

-8+28y=54

28y=54+8

y=62/28

y=31/14

Therefore the value of y is 31/14

Again,

Putting the value of y in ..

X=4+5y/3

=(4+5*31/14)/3

=(211/14)/3

=211/42

Step-by-step explanation:

So the value of X and y is 31/14 &211/42 respectively.

Answer:

if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.

We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.

Then draw a vertical line for your stem hopefully it is on lined paper.

single digits 1-9 go right side.

tenths get split keeping digits rights side

hundred units get split keeping tenth and single digits right side

and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.

Larger numbers that have 3 digits are more than double digits I've called 100th units

Numbers lower than 9 will be on rights side on the first line.

1-9  =  0 | 1  2 3 4 5 6 7 8 9

10-19   1 | 0 1 2 3 4 5 6 7 8 9

20-29  2| 0 1 2 3 4 5 6 7 8 9

100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line

We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.
