The perimeter of an isosceles triangle is 15.6 m. Find the lengths of its sides, if: Chapter Reference a The base is 3 m smaller
SSSSS [86.1K]

We know that an isosceles triangle has 2 equal sides.

We can represent the equal sides with x, and the base with y:

2x + y = 15.6

Given states that y = x - 3, so:

2x + x - 3 = 15.6

3x = 18.6

x  = 6.2

y = 3.2

The sides are 6.2 m, and the base is 3.2 m.

Tina bought some nail polish and lip gloss at the store. The nail polish cost $4.50 per bottle and lip gloss cost $7 per tube. T
Genrish500 [490]
Let Tina bought X number of nail polish any Y number of lip gloss.
then,      X+Y=9
           or,X=9-Y

Also,4.5 X+7 Y=50.5
  or,  4.5 (9-Y) +7 Y=50.5
  or,  Y =4.........................................(i)

so, X= 9-4
        = 5........................................(ii)
hence, she bought 5 nail polish and 4 lip gloss

almond37 [142]

Answer:

The correct option is - D.

Step-by-step explanation:

To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?

Solution -

We know that,

The parent tangent function is -

f(x) = tan(x)

Period of Parent function = \pi

Now,

If Period is half,

Then

The function is transformed to

f(x) = tan(2x)

So,

The graph becomes

The correct option is - D.
