Answer: A=28

Since it is an irregular shape you can split it in half to make two shapes.

Multiply

2x5=10

3x6=18

Add 28

so you multiply 6 and 3 and it is 18

Answer:

The height is 15 m.

Step-by-step explanation:

V = (pi)r^2h

375(pi) = (pi)(5^2)h

Divide both sides by 25pi.

15 = h

Answer: The height is 15 m.

Help me with this problem please

lions [1.4K]

3 circles are shown split into halves

so there are 6 halves (1/2) total

2 are fully colored and 1/2 of the 3rd is colored

so as a fraction it would be 5/6 ( 5 out of 6 halves are colored)

mixed number = 2 1/2 ( 2 and 1/2 circles are colored)

decimal would be 5/6 = 0.833

Take the logarithm of both sides. The base of the logarithm doesn't matter.

$4^{5x} = 3^{x-2}$

$\implies \log 4^{5x} = \log 3^{x-2}$

Drop the exponents:

$\implies 5x \log 4 = (x-2) \log 3$

Expand the right side:

$\implies 5x \log 4 = x \log 3 - 2 \log 3$

Move the terms containing x to the left side and factor out x :

$\implies 5x \log 4 - x \log 3 = - 2 \log 3$

$\implies x (5 \log 4 - \log 3) = - 2 \log 3$

Solve for x by dividing boths ides by 5 log(4) - log(3) :

$\implies \boxed{x = -\dfrac{ 2 \log 3 }{ 5 \log 4 - \log 3 }}$

You can stop there, or continue simplifying the solution by using properties of logarithms:

$\implies x = -\dfrac{ \log 3^2 }{ \log 4^5 - \log 3 }$

$\implies x = -\dfrac{ \log 9 }{ \log 1024 - \log 3 }$

$\implies \boxed{x = -\dfrac{ \log 9 }{ \log \frac{1024}3 }}$

You can condense the solution further using the change-of-base identity,

$\implies \boxed{x = -\log_{\frac{1024}3}9}$
