Answer:

8.6

Step-by-step explanation:

This uses the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 7

c = ?

5^2 + 7^2 = c^2

25 + 49 = c^2

74 = c^2

sqrt(c^2) = sqrt(74)

c = 8.60 which when rounded = 8.6

Find the first four terms of the sequence an = 4n-6

natulia [17]

Answer:

The first four terms of the sequence are-6, -2, 2 and 6

Step-by-step explanation:

The given sequence is $a_n=4n-6$

In order to find the first four term of the sequence we put n =0, 1, 2 and 3.

For n =0

$a_0=4(0)-6=-6$

For n =1

$a_1=4(1)-6=-2$

For n =2

$a_2=4(2)-6=2$

For n =3

$a_3=4(3)-6=6$

Therefore, the first four terms of the sequence are

-6, -2, 2 and 6

Write in descending powers of “x” 6x^4+15x^3y2+3x^2y^3

Wewaii [24]

(6x^4) + (15x^3)(y^2) + (3x^2)(y^3) is your answer

As we are looking at descending powers of x. Look at the powers of the x. In the first one (6x^4), the power is 4, and 4 is greater than the other numbers given (3 & 2). Therefore, the order given above is correct.

hope this helps
