The formula is K = v^2 /2

You are told K = 32.

Replace K and solve for v:

32 = v^2 / 2

Multiply each side by 2:

64 = v^2

Take the square root of both sides:

v = √64

v = 8 meters per second.

Suppose that the functions g and f are defined as follows.

Sholpan [36]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

$\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x$

Calculating the value of $(\frac{g}{f})(2)$ :

$\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times (2)$

$=\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\ =\frac{5}{-3}\\\\ = - \frac{5}{3}\\\\$

x= $- \frac{\sqrt{3}}{2}$ and x= $\frac{\sqrt{3}}{2}$ are not in the domain.

Domain: $x \belong (- \infty, -\frac{\sqrt{3}}{2})\cup (- \frac{\sqrt{3}}{2}, \frac{\sqrt{3}}{2} )\cup (\frac{\sqrt{3}}{2}, \infty)$

How do I write the sum of two numbers as the product of their GCF and another sum

Delicious77 [7]

Let's assume we were given 2 numbers: 15 and 30. Their sum is:
$15+30 = 45$
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
$\frac{15}{15} = 1$
$\frac{30}{15} = 2$
In this case sum of two numbers can always be written as:
$15+30 = (15\cdot 1) + (15\cdot 2) = 15\cdot (1+2) = 15\cdot 3 = 45$

What is the sum of ten terms of an infinite geometric series if the first term is 8 and the ratio is 1/2

xxTIMURxx [149]

Answer:

We use the formula:

S 10 = 8 · [(1/2)^9 - 1] / (1/2 - 1 );

Then, S 10 = 8 · ( 1/512 - 1 ) / ( 1/2 - 1 );

S 10 = 8 · ( - 511 / 512 ) / (-1 / 2 );

S 10 = ( - 511 / 64 ) · ( - 2 );

S 10 = + 511 / 32;
