Elsa tries to solve the following equation, and determines there is no solution. Is she correct? Explain.

Vlad [161]

Elsa's answer is incorrect since there is a solution of the given equation. In the given logarithmic problem, we need to simplify the problem by transposing log2(3x+5) in the opposite side. The equation will now be log2x-log2(3x+5)=4. Using properties of logarithm, we further simplify the problem into a new form log (2x/6x+10)=4. Then transform the equation into base form 10^4=(2x/6x+10) and proceed in solving for x value which is equal to 1.667.

For what values of x is x2-36=5x true?

katrin2010 [14]

Answer:

x=-12

Step-by-step explanation:

x2-36=5x

add 36 to both sides

x2=5x+36

subtract 5x from both sides

x(-3)=36

divide both sides by -3

x=-12

substitute to prove right

(-12)2-36=5(-12)

-24-36=-60

-60=-60

Assume that the number of hours of daylight in New Orleans in 1994 is given by the function D(x) = 7 3 sin 2π 365 x + 35 3 , whe

Bas_tet [7]

Answer:

Here, the given function that represents the number of hours of daylight in New Orleans in 1994 is,

$D(x) = \frac{7}{3} \sin \frac{2\pi }{365}x + \frac{35}{3}$

Where,

x = the number of days after March 21

The number of days from 1 January to march 21 = 80

If x = -80, then,

$D(-80) = \frac{7}{3} \sin \frac{2\pi }{365}(-80) + \frac{35}{3}$

$=\frac{7}{3} \sin (-\frac{160 \pi}{365}) + \frac{35}{3}$

$=-\frac{7}{3} \sin (\frac{160 \pi}{365}) + \frac{35}{3}$

$=-\frac{7}{3}(0.98130)+\frac{35}{3}$

$\approx 9.38$

Therefore, the number of hours of daylight on January 1 are 9.38.

The number of days from march 21 to may 4 = 44

If x =44, then,

$D(44) = \frac{7}{3} \sin \frac{2 \pi}{365}(44) + \frac{35}{3}$

$=\frac{7}{3} \sin (\frac{88 \pi}{365}) + \frac{35}{3}$

$=\frac{7}{3}(0.6870) + \frac{35}{3}$

$\approx 13.27$

Therefore, the number of hours of daylight on May 4 are 13.27.

The number of days from October 28 to may 4 = 221

If x = 221, then,

$D(221) = \frac{7}{3} \sin \frac{2 \pi}{365}(221) + \frac{35}{3}$

$=\frac{7}{3} \sin (\frac{442 \pi}{365}) + \frac{35}{3}$

$=\frac{7}{3}(-0.6152)+\frac{35}{3}$

$\approx 10.23$

Therefore, the number of hours of daylight on October 28 are 10.23.
