Find the value of x. A.4 B.5 C.6 D.9

ra1l [238]

The equation should be...

a^2 + b^2 = c^2

x^2 + (x+3)^2 =10.81665383^2

When you plug it in...

6^2 + (6+3)^2 = 117

6^2 + (9)^2 = 117

36 + 81= 117

The value of a professional basketball player's autograph rose 20% in the last year. It is now worth $336.00. What was it worth

sesenic [268]

Answer:

The value of basketball player's autograph a year ago is $280

Step-by-step explanation:

Given as :

The present value of autograph = $ 336.00

The rate of increase of autograph = 20%

The time period = 1 year

Let The value one year ago = $ x

So ,

The value of autograph after n year = The present value × $(1+\frac{Rate}{100})^{n}$

Or, $ 336.00 = $ x × $(1+\frac{20}{100})^{1}$

Or, $ 336.00 = $x × 1.2

∴ x = $\frac{336.00}{1.2}$ = $280

Hence The value of basketball player's autograph a year ago is $280 Answer

Simplify: 8i^7+6i^5-5i^3-3i^2-7i-9

Dmitry_Shevchenko [17]

Consider the remainder of the division of the power exponent of i by 4.
For a remainder r equal to 0, 1, 2 or 3, we have a power equal to 1, i, -1 or -i respectively, therefore:

 $8i^7+6i^5-5i^3-3i^2-7i-9 =$
$8*(-i) + 6*i - 5*(-i) - 3*(-1) - 7i - 9 =$
$- 8i + 6i + 5i + 3 - 7i - 9 =$
$3 - 9 - 8i + 6i + 5i- 7i =$
$=\boxed{- 6 - 4i}$

Answer:
$\boxed{- 6 - 4i}$
