Josh leans the ladder against a side of her house which is 10 feet. If the base of the latter is 3 feet away from the house, how

Galina-37 [17]

Answer:

$\sqrt{109}$

Step-by-step explanation:

The side of the house is a side of the right triangle.

The ladder is 3 feet away, so it forms a triangle with sides 3, 10, x.

We're trying to find the hypotenuse, which is given by Pythagoras' Theorem:

$a^2 + b^2 = c^2\\3^2 + 10^2 = x^2\\109 = x^2\\x = \sqrt{109}$

Log8 (t) - log8 (5) = 1

djyliett [7]

Answer:

t = 40

Step-by-step explanation:

Given the logarithmic expression: $log_8 (t) - log_8 5= 1$

Use the Logarithmic Property (Quotient Rule):

$log_b a - log_b c = log_b (\frac{a}{c})$

$log_8 (t) - log_8 5 = log_8 (\frac{t}{5}) = 1$

Next, using the Logarithmic Property: $log_b b= 1$

We must determine the possible value of t that can be divided by 5 to produce a quotient of 8 that will make the logarithmic property, $log_b b= 1$ , true. In that case, t = 40 divided by 5 results in a quotient of 8.

$log_8 (t) - log_8 5 = log_8 (\frac{t}{5}) = log_8 (\frac{40}{5}) = log_8 8 = 1$

Therefore, the value of t = 40.
