Letter A

Step-by-step explanation:

Pythagorean Triples $c^2=a^2+b^2$

A) Not a Pythagorean Triple

$40^2=12^2+35^2$ : 1,600 ≠ 144 + 1,225

B) Pythagorean Triple

$53^{2} = 28^{2} + 45^{2} :$ 2,809 = 784 + 2,025

C) Pythagorean Triple

$65^2= 33^2+56^2$ : 4,225 = 1,089 + 3,136

D) Pythagorean Triple

$85^{2} = 36^{2} + 77^{2}$ : 7,225 = 1,296 + 5,929

Which expression is equivalent to log_5(x/4)^2?

viktelen [127]

For this case we must find an expression equivalent to:

$log_ {5} (\frac {x} {4}) ^ 2$

So:

We expanded $log_ {5} ((\frac {x} {4}) ^ 2)$ by moving 2 out of the logarithm:

$2log_ {5} (\frac {x} {4})$

By definition of logarithm properties we have to:

The logarithm of a product is equal to the sum of the logarithms of each factor:

$log (xy) = log (x) + log (y)$

The logarithm of a division is equal to the difference of logarithms of the numerator and denominator.

$log (\frac {x} {y}) = log (x) -log (y)$

Then, rewriting the expression:

$2 (log_ {5} (x) -log_ {5} (4))$

We apply distributive property:

$2log_ {5} (x) -2log_ {5} (4)$

Answer:

An equivalent expression is:

$2log_ {5} (x) -2log_ {5} (4)$

E^4x-1=3 please help what is the exact solution

Roman55 [17]

combine like terms4ln(x) = 8

divide both sides by 4.ln(x) = 2

exponentiate both sides.eln(x) = e^2

inverse property of exponents and logs x = e^2

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

harina [27]

Answer:y=15/4

Step-by-step explanation:

start with general form y = kx. substitute in the pair of values you know for x and y.

75/8 = k(5) multiply both sides by 1/5 to solve for k, getting

15/8 = k

So your equation is y = (15/8)x substitute 2 for x to find your new y.

y = (15/8)2

y = 15/4
