Answer:

First one is 7.1415926,

Second one is $84 inch^{2}$

Step-by-step explanation:

First for the square plus the two half circles: The two half circles are semi-circles, so two semi-circles put together equals a full circle.

Equation for the circle:

$\pi (2/2)^{2} \\=\pi (1)^{2}$

= $\pi$

≅3.1415926 $inch^{2}$ (This is too long for me to write down, actually no body can write it down , since it's an infinity unrepeating decimal)

Then the square's area is:

$2^{2} \\=4$

Lastly 4+3.1415926

=7.1415926

Second one I am going to draw in the file first, then I'll write how I solved it here!

OK, so:

$(5)(10)+(7)(4)+(15-(5+7))(4)/2)\\=50+28+(12/2)\\=78+6\\=84 inch^{2}$

HOPED I helped!

_Izzy wants to paint three walls in her family room. Two walls are 13

stiks02 [169]

The total area would be the combined area of all three

Let’s knock out the first 2

4.5 * 13 = 58.5 * 2 = 117

Now the last

4.5 * 9 = 40.5

117 + 40.5 = 157.5 ft^2

Rewrite the form In exponential form: Log100 = x

andrey2020 [161]

Answer:

$10^x=100$

Step-by-step explanation:

You know how subtraction is the opposite of addition and division is the opposite of multiplication? A logarithm is the opposite of an exponent. You know how you can rewrite the equation 3 + 2 = 5 as 5 - 3 = 2, or the equation 3 × 2 = 6 as 6 ÷ 3 = 2? This is really useful when one of those numbers on the left is unknown. 3 + _ = 8 can be rewritten as 8 - 3 = _, 4 × _ = 12 can be rewritten as 12 ÷ 4 = _. We get all our knowns on one side and our unknown by itself on the other, and the rest is computation.

We know that $3^2=9$ ; as a logarithm, the exponent gets moved to its own side of the equation, and we write the equation like this: $\log_3{9}=2$ , which you read as "the logarithm base 3 of 9 is 2." You could also read it as "the power you need to raise 3 to to get 9 is 2."

One historical quirk: because we use the decimal system, it's assumed that an expression like $\log1000$ uses base 10, and you'd interpret it as "What power do I raise 10 to to get 1000?"

The expression $\log100=x$ means "the power you need to raise 10 to to get 100 is x," or, rearranging: "10 to the x is equal to 100," which in symbols is $10^x=100$ .
