I need help finding the values

Answers

Answer 1

Answer:

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x------> the number of minutes

y------> the depth in feet

In this problem the relationship between the variables, x, and y, represent a proportional variation

Remember that

A proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

step 1

Find the value of k

Let

$A(2,3)$ ------> see the given table

$k=y/x$ ----> substitute the values

$k=3/2=1.5$

The direct variation equation is equal to

$y=1.5x$

step 2

Complete the table

For $x=3\ min$

substitute the value of x in the equation and solve for y

$y=1.5(3)=4.5\ ft$

step 3

Complete the table

For $y=6\ ft$

substitute the value of y in the equation and solve for x

$6=1.5x$

$x=6/1.5=4\ min$

Z=2+5i. Convert the complex number to trigonometric form.

Answers

Answer:

$z = √(29) ( \cos \: 68 \degree + i \sin 68 \degree)$

Step-by-step explanation:

The trigonometric form of complex numbers is when the complex number is in polar form.

This is given by

$z = r( \cos \theta + i \sin \theta)$

where the modulus r is given by

$r = \sqrt{{2}^(2) + {5}^(2) }$

$r = √(4 + 25)$

$r = √(29)$

and the argument is given by

$\theta = \tan \:^( - 1) ( (y)/(x))$

$\theta = \tan \:^( - 1) ( (5)/(2))$

$\theta = 68 \degree$

The trigonometric form then becomes:

$z = √(29) ( \cos \: 68 \degree + i \sin 68 \degree)$

Find three solutions for y=-2x-1

Answers

Answer:

(1, -3)

(2, -5)

(3, -7)

Step-by-step explanation:

Randomly choose three values for "x". Substitute each of them separately into the formula to find the "y". Then write the solution as an ordered pair (x, y).

I will choose x=1, x=2 and x=3.

When x=1:

y = -2x - 1

y = -2(1) - 1

y = -2 - 1

y = -3

(1, -3)

When x=2:

y = -2x - 1

y = -2(2) - 1

y = -4 - 1

y = -5

(2 , -5)

When x=3:

y = -2x - 1

y = -2(3) - 1

y = -6 - 1

y = -7

(3, -7)

Three solutions for y = -2x - 1 are (0, -1), (2, -5), and (-3, 5), where x and y are related by this linear equation.

The equation y = -2x - 1 represents a linear relationship between x and y. To find three solutions for this equation, you can choose different values for x and calculate the corresponding values of y. Here are three solutions:

Solution 1:

Let x = 0:

y = -2(0) - 1

y = 0 - 1

y = -1

So, one solution is (0, -1).

Solution 2:

Let x = 2:

y = -2(2) - 1

y = -4 - 1

y = -5

So, another solution is (2, -5).

Solution 3:

Let x = -3:

y = -2(-3) - 1

y = 6 - 1

y = 5

So, a third solution is (-3, 5).

You can choose any values for x and calculate the corresponding y-values to find more solutions to this linear equation.

Helpp! im so confused on this question and i cant seem to get it right

Answers

Answer:

Step-by-step explanation:

To figure out if the table represents the same linear relationship as the equation, you take the x and y values from the table and plug them into the equation. So for table A, I plug in -5 for y and 0 for x, and see if the statement is true. So that turns into -5=(2x0)-5. 2 times 0 is 0, so it is -5=-5. If you keep plugging in for the rest of the numbers for table A, they all fit, therefore A is the right answer.

Round 8.54 to nearest tenth

Answers

If you look at the image below, you can find what the tenths place is.
Juts follow the rule: 5 or more raise the score, 4 or less stay and res(t)
Therefore 8.54 would raise to 8.5 Since the four is lower than five, it rounds down.
~Hope this helped :)

If the last number is less than 5, you will not round the number next to it, if the number is more than 5 or 5, you'll round
So the answer to this question is 8.5
