Mathematics
1 answer:
hammer [34]3 years ago
8 0

Answer:

19.2

Step-by-step explanation:

Cosine rule :

\sqrt{a^{2} +b^{2} ﹣2abcos(angle ) }

c will always be the hypotenuse.

a and b can be any if the opposite or the adjacent.

{15}^{2}  + 12^{2}  - 2 \times 15 \times 12 \times  \cos(90)  = 369

\sqrt{369}=19.20937...

A hot air balloon is currently at a height of 900 feet. The balloon is descending by 10 feet minute. Find a function for the bal
mylen [45]

Answer:

y=-10x+900

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the balloon's height in feet

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have that

The slope is equal to

m=-10\ \frac{ft}{min} ----> is negative because is a decreasing function

b=900\ ft

Remember that the y-intercept is the value of y when the value of x is equal to zero

In this context the y-intercept is the height of the balloon when the time is equal to zero (initial height)

substitute

y=-10x+900

Lim of tan(x) as x approaches pi/2. It does not ask from either the + or - direction, just pi/2. The answer is 0, but i think it
faltersainse [42]
Yes, you are right, if it approaches from the left, the limit is infinity and if it approaches from the right, the limit is negative infinity. The limit does not exist because it reaches infinity as x approaches pi/2 and the limits are the same when the value is approached from the opposite directions.

Which Postulate/Theorem below would prove that the triangles shown below are congruent?
velikii [3]

Answer:

Correct answer is <em>D. ASA</em>

<em />

Step-by-step explanation:

Let us first define <em>ASA congruence</em> rule:

2 triangles are called congruent according to ASA congruence rule if 2 angles of the triangle and the corresponding side between these two angles are <em>equal </em>to each other.

In the question figure, we can figure out following conclusions from Triangles \triangle SRT\text{ and }\triangle WXY respectively:

  1. \angle TRS = \angle YXW
  2. Side RS = Side WX
  3. \angle TSR = \angle YWX  

As per the definition of option d) ASA congruence, the triangles are congruent.
