Please help me with this math question. Thank you.

1/32

Step-by-step explanation:

1/4 divided by 8 equals 1/32 using calculator. No explanation really... Brainliest?

D

Step-by-step explanation:

We want to find the values of x such that:

We can use the quadratic formula. Recall that:

In this case, a = -1, b = 7, and c = 5. Substitute and evaluate:

In conclusion, the answer is D.

B

Step-by-step explanation:

Remember, perpendicular lines have NEGATIVE RECIPROCAL slopes! This means that a line with a slope of a/b's perpendicular line would be -b/a! You can see that in option B, the slopes of the lines are -7 and 1/7, which are negative reciprocals.

Let's take -7 and flip it, then change the sign:

-7 -> -7/1 -> -1/7 -> 1/7

We just confirmed that -7 and 1/7 are negative reciprocals! Therefore, two lines with these slopes are perpendicular.

(9, 5)

Step-by-step explanation:

Here's how to find the solution:

REMEMBER: THE SOLUTION SHOULD ALWAYS BE A COORDINATE POINT.

We already know that x = 9, so we can plug this into the second equation. This is because we want to solve for 'y.'

After plugging it into the equation, we can solve for the y-coordinate.

SOLUTION:

(a). Maximum = 3.66m   and   Mimimum = 2.76m

(b). At 16.1913 sec, the wave reaches again at 3.5m

These are the final answers.

Step-by-step explanation:

(a). From the given function, the amplitude |A| = 0.45 and vertical shift = 3.21.

Adding and subtracting the amplitude from the vertical shift will give us the maximum and minimum depth of water.

(b). Putting the values in the equation, we have:

Let's say, x is the time after 16 seconds at which the waves reaches the 3.5 again. So, we have:  

Using,

Solving for x, will give:

, putting for the first time after 16, will get us:

sec

So, seconds

x = 2

y = 2

Step-by-step explanation:

y = 3x-4

2x + y - 6 = 0

-3x+y = -4

2x + y = 6

-5x = -10

x = 2

y = 2

(a). Maximum = 3.66m   and   Mimimum = 2.76m

(b). At 16.1913 sec, the wave reaches again at 3.5m

These are the final answers.

Step-by-step explanation:

(a). From the given function, the amplitude |A| = 0.45 and vertical shift = 3.21.

(b). Putting the values in the equation, we have:

sec

So, seconds

I think C

if wrong correct me pls

have a nice day

42 degrees

Step-by-step explanation:

All the interior angles in a triangle add up to 180 degrees. Knowing this, we can construct the following equation:

Subtract both sides by 138

I hope this helps!

B

Step-by-step explanation:

Remember, perpendicular lines have NEGATIVE RECIPROCAL slopes! This means that a line with a slope of a/b's perpendicular line would be -b/a! You can see that in option B, the slopes of the lines are -7 and 1/7, which are negative reciprocals.

Let's take -7 and flip it, then change the sign:

-7 -> -7/1 -> -1/7 -> 1/7

We just confirmed that -7 and 1/7 are negative reciprocals! Therefore, two lines with these slopes are perpendicular.
