What is the following product

Genrish500 [490]

For this case we must find the product of the following expression:

$\sqrt [3] {5} * \sqrt {2}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

We rewrite the expression using the lowest common index of 6, then:

$5 ^ {\frac {1} {3}} * 2 ^ {\frac {1} {2}} =$

We rewrite the terms in an equivalent way:

$5 ^ {\frac {2} {6}} * 2 ^ {\frac {3} {6}} =$

We rewrite the expression using the property mentioned:

$\sqrt [6] {5 ^ 2} * \sqrt [6] {2 ^ 3} =$

We combine using the product rule for radicals:

$\sqrt [n] {a} * \sqrt [n] {b} = \sqrt [n] {ab}$

So:

$\sqrt [6] {5 ^ 2 * 2 ^ 3} =\\\sqrt [6] {25 * 8} =\\\sqrt[6]{200}$

-8 \cdot f(0) + 4 \cdot g(-8) =−8⋅f(0)+4⋅g(−8)=

kogti [31]

Answer:

$-8f(0) +4g(-8)=-32$

Step-by-step explanation:

Given

See attachment

Required

$-8f(0) +4g(-8)$

From the attachment;

$f(0) = 1$

and

$g(-8) = -6$

Substitute these values in $-8f(0) +4g(-8)$

$-8 * 1 + 4 * -6$

$-8 -24$

$-32$

Hence:

$-8f(0) +4g(-8)=-32$

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I

Margarita [4]

Let A be attendance, t the temperature and n the number of days. Then,
A $\alpha$ $\frac{t}{n}$
A=k $\frac{t}{n}$
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200= $\frac{88k}{8}$
3200=11k
k= $\frac{3200}{11}$
Rewriting the equation and replacing the value of k,
A= $\frac{3200t}{11n}$
When t=92 and n=12
The A= $\frac{3200*92}{11*12}$
A= $\frac{294400}{132}$
A= 2231
