Please help me with number 4!
Mariulka [41]

Answer:

x = 20√2 and y = 20√3.

or x = 28.28 and y = 34.64 to the nearest hundredths.

Step-by-step explanation:

Take the 2 'inside' triangles. They are similar.

So we have  x / (60-40) = 40 / x

x/ 20 = 40 /x

x^2 = 800

x = √800

x = 20√2

y = √(800 + 20^2)

= √(1200)

= 20√3.

Delvig [45]

Answer:

a_n = 3 ({5})^{n - 1}

Step-by-step explanation:

The given sequence is 3,15,75,375,...

The first term of this geometric sequence is

a_1=3

The common ratio is

r =  \frac{15}{3}  = 5

The explicit formula is given by:

a_n = a_1 {r}^{n - 1}

We plug the first term and common ratio into the formula to get:

a_n = 3 ({5})^{n - 1}
