If y is directly proportional to x and y = 11 when x = 6 , what is the value of y when x = 9

Mathematics

REY [17]3 years ago
3 0
Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
\frac{11}{6} = \frac{y}{9}
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is 16.5. Hope this helped and have a phenomenal day!

Using the slope concept, it is found that:

  • The minimum horizontal distance is of 14,281.5 feet.
  • The maximum horizontal distance is of 15,398.6 feet.

<h3>What is a slope?</h3>
  • The slope is given by the <u>vertical change divided by the horizontal change</u>.
  • It's also the tangent of the angle of depression.

In this problem, the vertical change is the altitude of 10,000 feet.

The minimum horizontal distance is with an angle of 35º, hence:

\tan{35^{\circ}} = \frac{10000}{d}

d = \frac{10000}{\tan{35^{\circ}}}

d = 14281.5

The maximum horizontal distance is with an angle of 33º, hence:

\tan{33^{\circ}} = \frac{10000}{d}

d = \frac{10000}{\tan{33^{\circ}}}

d = 15398.6

-9 - (18v - 5) = 2(7v - 16) - 3v​
andrezito [222]

Answer:

v = 28/29

Step-by-step explanation:

- 9 - (18v - 5) = 2(7v - 16) - 3v​

- 9 - 18v + 5 = 14v - 32 - 3v

- 18v - 14v + 3v = - 32 - 5 + 9

- 29v = - 28

v = -28 / -29

v = 28/29

Answer:

3.605 ft is the answer.

Step-by-step explanation:

Applying Pythagoras theorem,

a^2 + b^2 = c^2

2^2 + 3^2 = c^2

4 + 9 = c^2

13 = c^2

3.605 = c

therefore, the answer is 3.605.
