Answer:

Option B, 3.27

Step-by-step explanation:

Given -

The submerged vessel travel horizontal distance above the shipwrecked hull

= 400

= 0.4 kilometers

The vertical distance from the the shipwrecked hull to the ground is equal to 7 kilometers

There forms a right angled triangle with

Base = 7 kilometer

Perpendicular = 0.4 kilometer

Tan (angle) = \frac{Perpendicular}{Base}

Substituting the given values we get -

Angle of depression

= tan^{-1}(\frac{0.4}{7})\\= 3.27

Hence, option B is correct.

Solve for missing variable d=rt, r=57, t=4
____ [38]

D=228

when 2 numbers or variables are next to eachother it means you need to multiply. So in this case r=57 and t=4 and we mulitply. 57 x 4 = 228.  So the answer is 228. Hope this helps and have a great day!

Solve the equation. StartFraction dy Over dx EndFraction equals5 x Superscript 4 Baseline (1 plus y squared )Superscript three h
dangina [55]

Answer:

Step-by-step explanation:

To solve the differential equation

dy/dx = 5x^4(1 + y²)^(3/2)

First, separate the variables

dy/(1 + y²)^(3/2) = 5x^4 dx

Now, integrate both sides

To integrate dy/(1 + y²)^(3/2), use the substitution y = tan(u)

dy = (1/cos²u)du

So,

dy/(1 + y²)^(3/2) = [(1/cos²u)/(1 + tan²u)^(3/2)]du

= (1/cos²u)/(1 + (sin²u/cos²u))^(3/2)

Because cos²u + sin²u = 1 (Trigonometric identity),

The equation becomes

[1/(1/cos²u)^(3/2) × 1/cos²u] du

= cos³u/cos²u

= cosu

Integral of cosu = sinu

But y = tanu

Therefore u = arctany

We then have

cos(arctany) = y/√(1 + y²)

Now, the integral of the equation

dy/(1 + y²)^(3/2) = 5x^4 dx

Is

y/√(1 + y²) = x^5 + C

So

y - (x^5 + C)√(1 + y²) = 0

is the required implicit solution

Give each answer as mixed number in simplest form
telo118 [61]

Step-by-step explanation:

=  \frac{1}{2}  +  ( - 5 \frac{9}{10} )

=  \frac{1}{2}  - 5 \frac{9}{10}  \\

=  \frac{1}{2}  -  \frac{5 \times 10 + 9}{10}  \\

=  \frac{1}{2}  -  \frac{59}{10}  \\

=  \frac{1}{2}  \times  \frac{5}{5}  -  \frac{59}{10}  \\

=   \frac{5}{10}   -  \frac{59}{10}  \\

=  \frac{5 - 59}{10}  \\

=  -  \frac{54}{10}  \\

=  -  \frac{27}{5}  \\
