The value of the expression ((-1/3)^3)^-3 is option (D)  -19683

The given expression is

((-1/3)^3)^-3

The exponent is defined as the number of times the number is multiplied by its self. If the exponent is a^m, then the number a is multiplied m times

According to the power of the power rule is

(a^m)^n = a^(m×n)

We have to apply the power of the power rule in this question

((-1/3)^3)^-3 = (-1 / 3)^(3 × -3)

Multiply the numbers

=(-1 / 3)^-9

We know

(1/a)^-b = a^b

Then the terms will become

= -3^9

Find the power of the number

= -19683

Therefore, the result is -19683

What is water level?

It is mark for safe amount of water in seas oceans etc and which is safe for Humans and Nature but sometimes due to heavy rains water level increase that is not good most of the times

Solution:

Here we can see water level rise per day = 2.6 inch

and rain continued for 4 days

hence after 4 days total water level reached = 2.6(4) = 10.4 inches

The slope of the line in the function is 1

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,

m = y₂ - y₁ / x₂ - x₁

Taking two points;

Substituting the values into the formula;

m = -2 - 0 / 3 - 5

m = -2 / - 2

1. The translation was of 4 units right and 3 units down.

2. All the blue lines connecting the equivalent vertices will have a slope of -3/4.

The translations of the triangle is given by the rule presented as follows:

(x,y) -> (x + 4, y - 3).

Hence the meaning of each of these translations is given as follows:

The coordinates of the original vertices are given as follows:

(0,0), (0,4), (3,0).

Then the coordinates of the translated vertices are given as follows:

(4,-3), (4,1), (7,-3).

For a linear function, the slope is given by the vertical change divided by the horizontal change.

From these translations, the changes are given as follows:

Thus the slope of the linear function connecting the original vertices are given as follows:

Step-by-step explanation:

Slope of the line having passing points (6,-5) and (-6,-5) is 0.

What do you mean by slope of the line?

A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

Hence, the change in y-coordinate with regard to the change in x-coordinate is given by,

m =  change in y/change in x

Given passing points :

(6,-5) and (-6,-5)

Slope of the line having passing points (x,y) and (a,b) is given by [tex]\frac{b-y}{a-x}[/tex]

Slope of the line become , [tex]\frac{-5+5}{-6-6}[/tex] = [tex]\frac{0}{-12}=0[/tex]

Comparing the √17 and 29/7 using <, > or = , we have √17 < 29/7.

Mathematical number comparison is the process or method of comparing two numbers to determine whether one is less, bigger, or equal to the other. The comparison symbols for numbers are "=", which stands for "equal to," "=", which stands for "greater than," and " ", which stands for "less than." Comparing amounts is a technique for figuring out how much to compare units in relation to a different standard or reference unit. A common reference point is necessary for two comparing units to be compared; otherwise, they cannot be compared.

Given,

The angle measurement of T is 80°.

Here given,

∠Q = (9x - 17)°

∠R = (4x + 28)°

Since ∠Q and ∠R are co-interior angles in parallel lines.

∠Q + ∠R = 180°

So,

(9x - 17) + (4x + 28) = 180°

= 9x - 17 + 4x + 28 = 180°

By adding x variables together,

13x + 11 = 180°

=>  13x = 180°-11

=> x = 169° ÷ 13

x = 13

By substituting x,

∠Q = 9 x 13 - 17

      = 117 - 17

      = 100°

∠Q + ∠T = 180° (angles on a straight line is 180°)

100 + ∠T = 180°

∠T  = 180 - 100

∠T  = 80°

Therefore the value of  ∠T is 80°.

Answer:

x = 19

Step-by-step explanation:

So cos and sin are closely related, but they are not equal. In order for these two to be equal to each other, the angles (in the parenthesis by the cos and by the sin) have to be complementary. That is, they have to add up to 90°

Use this idea to set up an equation.

x + 16 + 3x - 2 = 90

Combine like terms.

4x + 14 = 90

Subtract 14.

4x = 76

Divide by 4.

x = 19

x = 19

If you are kooking for the angles:

x + 16

= 19 + 16

= 35

and

3x - 2

= 3(19) - 2

= 57 - 2

= 55

Check: 35 + 55=90

Also,

cos35 = sin55

We can consider that table (A) shows a proportional relationship of 7/1.

Relationships between two variables that are proportional occur when their ratios are equal.

Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value.

The "constant of proportionality" is the name of this constant.

So, consider the tables as follows:

Table A:

7/1

14/2 = 7/1

28/4 = 7/1

35/5 = 7/1

Proportional relationship: 7/1

Now, we don't need to calculate further.

Therefore, we can consider that table (A) shows a proportional relationship of 7/1.
