Answer:

Depth of the submarine = 668.09 feet

Step-by-step explanation:

From the figure attached,

In triangle ABC,

Distance between a navy cruiser and a nuclear submarine = 2500 feet

Angle between the water level and the submarine = 15.5°

By applying sine rule in the given triangle,

sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]

sin(15.5°) = [tex]\frac{BC}{2500}[/tex]

BC = 2500[sin(15.5)]

BC = 668.09 feet

Therefore, submarine is 668.09 feet deep in the sea.

Answer:

  (3)  y = (x -3)²

Step-by-step explanation:

Try the first value of x in each function:

  (1)  y = 3² -3 ≠ 0

  (2)  y = (3 +3)² ≠ 0

  (3)  y = (3 -3)² = 0 . . . . . . matches the table value for f(3)

  (4)  y = 3² +3 ≠ 0

Answer: 6000,00

Step-by-step explanation:

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Step-by-step explanation:

The average rate of change will be "55 m/h".

According to the question,

→ After 2 hours (t₁),

Juan is 110 miles (d₁) from his home.

→ After 5 hours (t₂),

Juan is 275 miles (d₂) from his home.

→ The average rate of change will be:

= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]

By substituting the values, we get

= [tex]\frac{110+275}{2+5}[/tex]

= [tex]\frac{385}{7}[/tex]

= [tex]55 \ m/h[/tex]

Thus the above is the right solution.

Step-by-step explanation:

Answer:

sin(A) = 16*Cos(A)/63

Step-by-step explanation:

You didn't state what quadrant it was in.

The sine of angle A is 16 / 65

In a right-angled triangle, the sine of an angle is equal to the ratio of the side opposite to the angle (also called perpendicular) and hypotenuse.

Give that, cot A = 63/16 and that angle A is in Quadrant, (refer to the figure attached)

Since, we know that, cotangent of an angle is ratio of adjacent side to opposite side.

Using Pythagoras theorem, we get,

63²+16² = 4255

√4225 = 65

Therefore, the hypotenuse = 65

sine of an angle = opposite side / hypotenuse

sinA = 16 / 65

Hence, the sine of angle A is 16 / 65

[tex](x-2)^2+(y-5)^2=9^2[/tex]

Step-by-step explanation:

We use the equation

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Now we plug in the numbers

(h, k) = center point (2, 5)

This would equal

Answer: 1. 34 degrees+34 degrees=68 180-68=112 so x=112 degrees

2. 84+22=106 180-106=74 so x=74 degrees

3. 126+20=146 180-146=34 so x=34 degrees

4. both angles on both sides are 40 so 40+40=80 180-80=100 so x=100 degrees
