4 0

So, 5/2 could also be written as 2.5.

2.5^2    or   2.5 x 2.5 = 6.25

3/4^3   is  3/4 x 3/4 x 3/4

3/4 x 3/4 x 3/4 = 0.46875

6.25 + 0.46875 = 6.71875!

a sequence of numbers begins at 400. If the pattern increases by consecutive multiples of 5 starting with 5, then find the next
bazaltina [42]

Given :

A sequence of numbers begins at 400.

To Find :

If the pattern increases by consecutive multiples of 5 starting with 5, then find the next 3 numbers in the sequence 400, ___, ___, ___ .

Solution :

This is the a question of arithmetic progression .

The first term is , a = 400 .

Now , it is given that the next numbers increase by the multiples of 5 starting with 5 .

So , common difference is , d = 5 .

Now , we know , n^{th} number in A.P is given by :

a_n=a+(n-1)d

Putting value of n = 2 , 3 , 4 .

We get :

a_2=a+(2-1)d=400+5=405\\\\a_3=a+(3-1)d = 400 + (5\times 2) = 410\\\\a_4=a+(4-1)d = 400 +(5\times 3)=415

Therefore , the next 3 numbers in the sequence is 400 , 405 , 410 , 415 .

Hence , this is the required solution .

Use a special right triangle to write sin 30° as a fraction.
borishaifa [10]

Answer:

1/2

Step-by-step explanation:

So do this, think of an equilateral triangle. A 30-60-90 triangle is just half of an equilateral triangle. If the original side length was x, then the hypotenuse is x, one leg is x/2, and the third, by Pythagorean theorem, is x sqrt3

Sin is opposite over hypotenuse, so we have (x/2)/x = 1/2
