Log k-log(k-2)=log25

Studentka2010 [4]

Answer:

k = $\frac{25}{12}$

Step-by-step explanation:

Using the rules of logarithms

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

log a = log b ⇒ a = b

Given

logk - log(k - 2) = log25, then

log ( $\frac{k}{k-2}$ ) = log25, thus

$\frac{k}{k-2}$ = 25 ( multiply both sides by (k - 2)

25(k - 2) = k

25k - 50 = k ( subtract k from both sides )

24k - 50 = 0 ( add 50 to both sides )

24k = 50 ( divide both sides by 24 )

k = $\frac{50}{24}$ = $\frac{25}{12}$

Determine the volume of the figure that has a radius of 2 feet. Round your answer to nearest tenth of a cubic foot

Sindrei [870]

Answer: 138.2 ft³

Step-by-step explanation:

The area of the figure is:

$V_f=V_{cylinder}+V_{cone}$

Calculte the volume of the cylinder:

$V_{cylinder}=hr^2\pi$

Where r is the radius ( $r=2ft$ ) and h is the height.

Then:

$V_{cylinder}=(10ft)(2ft)^2\pi=125.66ft^3$

Calculte the volume of the cone:

$V_{cone}=\frac{1}{3}hr^2\pi$

Where r is the radius ( $r=2ft$ ) and h is the height.

Then:

$V_{cone}=\frac{1}{3}(3ft)(2ft)^2\pi=12.56ft^3$

Therefore:

$V_f=125.66ft^3+12.56ft^3=138.2ft^3$

8-2 (i+1) < 12 − 7i + 4i true.

IrinaK [193]

Answer:

True

Step-by-step explanation:

8-2 (i+1) < 12 − 7i + 4i

Left side of the inequality:

8 - 2(i + 1) distribute

8 - 2i - 2 simplify

(8 - 2) - 2i

6 - 2i

Right side of the inequality:

12 − 7i + 4i simplify

12 − 3i

Combine:

6 - 2i < 12 − 3i

6 is less than 12

3i is less than 2i

leads to the assumption that the statement is true
