Answer:

B

Step-by-step explanation:

Since you have the adjacent value, the best way to do this is with tangent. You can do tan(50) = x/3. From there you multiply by 3, and get x = 3(tan50)

Geoff and Max are college roommates. Geoff can clean their apartment in 2.5 hours and Max can clean their apartment in 3.25 hour
Anestetic [448]

Answer: 1.41 hours

<u>Step-by-step explanation:</u>

Geoff: 2.5 hours = 1 job

Max: 3.25 hours = 1 job

Together: \frac{x}{2.5} + \frac{x}{3.25} = 1 job

            ⇒ (3.25)(2.5)\frac{x}{2.5} + (3.25)(2.5)\frac{x}{3.25} = (3.25)(2.5)1

            ⇒ 3.25x + 2.5x = 8.125

            ⇒             5.75x = 8.125

                           <u>÷5.75  </u>  <u> ÷5.75 </u>

                                   x = 1.413

If you apply the changes below to the absolute value parent function, f(x) = |Xl,
TiliK225 [7]

Answer:

• Shift 5 units to the left  >>>  f(x) = |x+5|

• Shift 4 units down >>>  f(x) = |x| - 4

Step-by-step explanation:

If we have the parent function:

f(x) = |x|

<u>For horizontal translations:</u>

  • |x-a| means horizontally translated a units right
  • |x+a| means horizontally translated a units left

<u>For Vertical translation:</u>

  • |x| + b means vertically translated b units up
  • |x| - b means vertically translated b units down

From the translation rules, we can say:

Shift 5 units left would be:

|x+5|

and

Shift 4 units down would be:

|x| - 4

An atom has a charge of +1. If the atom's nucleus contains 23 protons, the atom must have
Ymorist [56]
If an atom has a let's say, +2 charge, it will mean that the atom has two more protons than electrons. Protons have +1 charges and electrons have -1 charges. So, said this, if you had one more proton than an electron, it would be a -1 charge. Because of this, if an atom had a +1 charge, it would have to have one more proton than electrons. So, the answer could be "the atom must have 22 electrons" but, the question is sort of vague? It could really be anything.
