How does the graph of mc024-1.jpg compare to the graph of the parent function mc024-2.jpg?
ss7ja [257]
The question is as following:
<span>How does the graph of g(x)=1/x-5+2 compare to the graph of the parent function f(x)=1/x ?
</span>
=================================================
Solution :
========
The given function ⇒ g(x) = \frac{1}{x-5} +2

The parent function of the given function ⇒ f(x)= \frac{1}{x}

By graphing both of the equations as shown in the attached figure.
So, we can conclude the following 
<span>g(x) is shifted 5 units right and 2 units up from f(x).
</span>

So, the correct answer is option 2

Which of the following expressions are equivalent to −5.93+(−8.62)+5.93?
vampirchik [111]

Answer:

  • A, B, C, D

Step-by-step explanation:

  • −5.93 + (−8.62) + 5.93 =
  • −5.93 - (8.62 - 5.93) =         B
  • −(5.93 + 8.62) + 5.93 =       C
  • −5.93 −8.62 - (- 5.93) =       D
  • -8.62                                    A

In isosceles △ABC (AC = BC) with base angle 30° CD is a median. How long is the leg of △ABC, if sum of the perimeters of △ACD an
SIZIF [17.4K]

Note necessary facts about isosceles triangle ABC:

  • The median CD drawn to the base AB is also an altitude to tha base in isosceles triangle (CD⊥AB). This gives you that triangles ACD and BCD are congruent right triangles with hypotenuses AC and BC, respectively.
  • The legs AB and BC of isosceles triangle ABC are congruent, AC=BC.
  • Angles at the base AB are congruent, m∠A=m∠B=30°.

1. Consider right triangle ACD. The adjacent angle to the leg AD is 30°, so the hypotenuse AC is twice the opposite leg CD to the angle A.

AC=2CD.

2. Consider right triangle BCD. The adjacent angle to the leg BD is 30°, so the hypotenuse BC is twice the opposite leg CD to the angle B.

BC=2CD.

3. Find the perimeters of triangles ACD, BCD and ABC:

P_{ACD}=AC+CD+AD=2CD+CD+AD=3CD+AD;

P_{BCD}=BC+CD+BD=2CD+CD+AD=3CD+AD;

P_{ABC}=AC+BC+AB=2CD+2CD+AD+BD=4CD+2AD.

4.  If sum of the perimeters of △ACD and △BCD is 20 cm more than the perimeter of △ABC, then

P_{ACD}+P_{BCD}=P_{ABC}+20,\\ \\3CD+AD+3CD+AD=4CD+2AD+20,\\ \\6CD+2AD=4CD+2AD+20,\\ \\2CD=20.

5. Since AC=BC=2CD, then the legs AC and BC of isosceles triangles have length 20 cm.

Answer: 20 cm.
