Answer:

x is tangent of 39 = x/ 19, tangent of 39 is 3. 615...... then 19 multiply by 3.615....., x would get 68. 68

Step-by-step explanation:

tangent is opposite over adjacent then put all your numbers in to the formula.

The rate of change of the volume of a snowball that is melting is proportional to the surface area of the snowball. Suppose the

Alisiya [41]

Answer:

According to the passage, we have the next equation:

$\frac{dV}{dt} = \frac{4}{3}\pi*3*r^{2}*\frac{dr}{dt} = K*(4\pi*r^{2} )$

where "K" is a proportional constant

Leaving at the end with the next equation:

$\frac{dr}{dt} = K$

Integrating the equation, we have:

$r=K*t+C$

where "C" is a constant

Then, we have the 2 conditions for the problem:

1) t=0 → r=10

Replacing in the equation, we have C = 10

2) t=5 → r=8

Replacing in the equation, we have K = -0.4

Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation

$0=-0.4*t+10$

t = 25 minutes

What is the value of x?<br>x=____

Setler79 [48]

The answer is x = 6

To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2

In this problem a = x b = 8 and c = 10

You would then square these numbers
x^2 + 64 = 100

Next, you would subtract 64 from both sides.

x^2 = 36

All that’s left is the find the square root, which is x = 6.

So, therefore, you’re answer is x = 6

Given the following relations on the set of all people. Check ALL correct answers from the following lists:

(a) a is older than b;

A. antisymmetric

B. irreflexive

C. transitive

D. reflexive

E. symmetric

(b) a and b have a common grandparent;

A. reflexive

B. symmetric

C. irreflexive

D. transitive

E. antisymmetric

A. reflexive

B. irreflexive

C. transitive

D. symmetric

E. antisymmetric

(d) a and b were born on the same day;

A. symmetric

B. reflexive

C. transitive

D. antisymmetric

E. irreflexive

Answer:

a) Options A, B & D.

b) Options C & D.

c) Options C, D & E

d) Options A, B & C

Step-by-step explanation:

a) Options A, B & D.

- It's irreflexive because b is not older than a.

- It's transitive because if a is older than b as we are told and b is older than c, then we can say that a is older than c.

- It's antisymmetric because if a is older than b, then we can say that b is not older than a.

b) Options C & D.

- It's symmetric because if a & b have a common grandparent, then we can say that b and a have a common grandparent.

- It's reflexive because a and b have common grandparents and thus implies all of a's grandparents.

c) Options C, D & E are correct.

It could be Transitive, symmetric or antisymmetric.

d) Options A, B & C are correct.
