The value of x will be equal to x = 79.

<h3>What is the triangle?</h3>

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.

The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-

Angle = 180 - 142 - 19 = 19

Now applying Lami's theorem in the triangle we will get the third side.

\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}

\dfrac{Sin 19}{42}= \dfrac{Sin142}{x}

x = \dfrac{42\times Sin 142}{Sin19}

x = 79

Therefore the value of x will be equal to x = 79.

The Super Bounce brand of bouncy balls rebounds to 85% of the height from which it was dropped. Write both the explicit and recu
jarptica [38.1K]

Answer:

Explicit formula is h(n)=4(0.85)^{n-1}.

Recursive formula is h_n=0.85h_{n-1}

Step-by-step explanation:

Step 1

In this step we first find the explicit formula for the height of the ball.To find the explicit formula we use the fact that the bounces form a geometric sequence. A geometric sequence has the general formula ,a_{n+1}=ar^{n-1}. In this case the first term a_o=4, the common ratio r=0.85 since the ball bounces back to 0.85 of it's previous height.

We can write the explicit formula as,

h(n)=4(0.85)^{n-1}.

Step 2

In this step we find the recursive formula for the height of the ball after each bounce. Since the ball bounces to 0.85 percent of it's previous height, we know that to get the next term in the sequence, we have to multiply the previous term by the common ratio.  The general fomula for a geometric sequene is a_n=a_{n-1}\times r.

With the parameters given in this problem, we write the general term of the sequence as ,

h(1)=4\\h(n)=h_{n-1}\times 0.85.
