How do you solve (4x)2/3

1 answer:

4 0

3.1 Solve : 4x2+3 = 0. Subtract 3 from both sides of the equation : 4x2 = -3. Divide both sides of the equation by 4: x2 = -3/4 = -0.750. When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: x = ± √ -3/4. In Math, i is called the imaginary unit. It satisfies i 2 =-1.

gavmur [86]

Answer:

450

Step-by-step explanation:

A = P(1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time(in years)

Given,

P = 3000

t = 2 years

r = 7.5% = 7.5/100 = 0.075

A = 3000(1 + 0.075*2) = 3450

Interest = 3450 - 3000 = 450

Find the volume of a square pyramid with slant height = 13cm, and base edges = 10cm

IrinaK [193]

Check the picture below

notice, is a "square" pyramid, so its base is a square,if one edge is 10, all are 10

$\bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}Bh\qquad 
\begin{cases}
B=\textit{base area}\\
h=height\\
------\\
B=10\cdot 10\\
h=12
\end{cases}\implies V=\cfrac{1}{3}(10\cdot 10)12$
