Find the average of the list of numbers.
- 18, - 29, - 17, - 12
Daniel [21]4 years ago

The problem should look like this:

-16+(\frac{x}{-4}) =-3

The quotient means the answer given when two numbers are divided. The two numbers are an unknown value (x) and -4.

The rest of the problem is solved here:

-16+(\frac{x}{-4}) =-3\\ \\ \frac{x}{-4}=-3+16\\ \\ \frac{x}{-4}=13\\ \\ x=13(-4)\\ \\ x=-52

So if your solving for x this would be the answer. If you're just looking for how the problem is set up as the answer then the answer is the first equation given : -16+(\frac{x}{-4}) =-3

Hope this helps!

X^2 - 9x -10 =0 has a discriminant of: a. 121 b. 72 c. -359 d. 41 e. 136
Feliz [49]
In the standard form of quadratic
ax^{2} +bx+c
the discriminant is
b^{2} -4ac
In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.

The two men measure the angle of elevation to the highest point on the rock to be 22.6°. They
IgorC [24]

Answer:

  • 15 m

Step-by-step explanation:

<em>Refer to attached picture</em>

  • The height  = h
  • Angles of elevation 22.6° and 38.3°
  • Closer distance  = d

<u>Use tangent to solve</u>

  • tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)
  • tan 38.3° = h/d          ⇒ h = d tan 38.3°           ⇒ h = 0.79d

<u>Compare the equations above and find the value of d:</u>

  • 0.42(d + 17) = 0.79d
  • 0.42d + 7.14 = 0.79d
  • 0.79d - 0.42d = 7.14
  • 0.37 d = 7.14
  • d = 7.14/0.37
  • d = 19.3 m

<u>Now find the value of h:</u>

  • h = 0.79d
  • h = 0.79*19.3
  • h = 15
