We have:

√32x + 1 = 9x - 2

<=> √32x - 9x = -2 - 1

<=> (√32 - 9)x = -3

<=> x = -3/(√32 - 9) = (27+12√2)/49

ANSWER: x = (27+12√2)/49

P/s: i'm not pretty sure

Ok done. Thank to me :3

If n is a term of the sequence 14, 8, 2, -4, …, which expression would you give the value of n?

Ipatiy [6.2K]

Answer:

-6n+20

Step-by-step explanation:

The given term of sequece is 14, 8, 2, -4, …,

Here the first term is 14 and then the terms are decreasing by 6 each time because $14-8=8-2=...=6$

As we know that the nth term of the sequence is given by the formula

$t_n=a+(n-1)d\\\text{Substitute the values we get}\\t_n=14+(n-1)(-6)\\t_n=14-6n+6\\t_n=20-6n\\$

If n is a term of the given sequence sequence, then its value is -6n+20

Elis [28]

The area of a circle is given in terms of its radius by

A = π · r²

Your circle has r=4 (half the diameter) and you want π=3.14. Using these values in the formula gives

A = 3.14 · 4²

This matches your first selection

3.14 · 4²

What is the value of x?

guajiro [1.7K]

Answer:

x ≈ 8.66

Step-by-step explanation:

Using the sine ratio in the right triangle

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{10}$

Multiply both sides by 10

10 × sin60° = x, thus

x ≈ 8.66 ( to 2 dec. places )
