Determine the value of x.

Answer: 9 feet below the surface.

Step-by-step explanation:

The scuba diver starts 40 ft below the surface. We can represent the position of the scuba diver as:

Position = -40ft

Where the negative sign is because it is below the surface of the water, so

"He swam up 12 feet to see a unique fish."

Now we need to add 12ft

Then his new position is:

Position = -40ft + 12 ft = -28ft

"He followed the fish down 8 feet.

Now we need to subtract 8ft

His new position is:

Position = -28ft - 8 ft = -36 ft

"Then he followed the fish up 27 feet."

Now we add another 27 ft.

The final position will be:

Position = -36ft + 27ft = -9ft

Then the final position of the scuba diver is -9ft, that means that he is 9 feet below the surface.

Answer:

Step-by-step explanation:

Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z

Note that sin theta = cos(90-thetsa)

sin(9z − 1) = cos(6z + 1)

cos (90 - (9z-1)) = cos(6z + 1)

cos (90 - 9z+1)) = cos(6z + 1)

cos (91-9z) = cos(6z + 1)

Cos will cancel out to have;

91-9z = 6z+1

-9z - 6z = 1-91

-15z = -90

z = 90/15

z = 6

Hence the value of z is 6

,LCM of 12 and 30 is 60

Answer:

List the first five multiples of 30

The first 5 multiples of 30 are: 0, 30, 60, 90, 120.

What is the lowest common multiple of 12 and 30

for LCM (12,30) we find:

Prime factorization of 12 = 2 × 2 × 3.

Prime factorization of 30 = 2 × 3 × 5.

Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.

Therefore LCM (12,30) = 60

Answer:

Reference Point

Step-by-step explanation:

The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.

Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.

Answer:

1056 inches

Step-by-step explanation:

Given that :

Initial measurement = 2358 in

Guage level after 5 days of rain (final reading) = 3414 in

Change in water level rise :

Final reading - Initial reading

(3414 - 2358) in

= 1056 inches

Answer:

5/4

Step-by-step explanation:

Rise over run you go up 5 and left 4 so 5/4 is the ROC.

The rate of change of the function is given by the slope of the line m = -4/3

The equation of a line is y = mx + b where m is the slope which is the rise by run and b is the y-intercept

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

Given data ,

Let the rate of change of the function be m

The equation is represented as A

Now , the value of A is

Let the first point be P ( 0 , 4 )

Let the second point be Q ( 3 , 0 )

Slope m = -4/3

On simplifying the equation , we get

Slope m = -4/3

Now , the equation of line is

y - 4 = ( -4/3 ) ( x - 0 )

On simplifying the equation , we egt

y - 4 = ( -4/3 )x

y = ( -4/3 )x + 4

Hence , the equation of line is y = ( -4/3 )x + 4 and the rate of change of the function is m = -4/3

The size of the angle x is 13°

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

From the figure,

Let the triangle having ∠x have the following angles:

∠A and ∠B.

Now,

∠A is opposite to 85°.

So,

∠A = 85°

98° and one angle are corresponding angles.

So,

One angle = 98°

Now,

One angle and ∠B is a straight angle.

So,

∠B + 98 = 180

∠B = 180 - 98

∠B = 82°

Now,

The sum of the triangle is 180.

This means,

x + 82 + 85 = 180

x = 180 - 167

x = 13

Thus,

The value of x is 13.
