The answer is C)48 square cm , because to find the area of 1 rectangle you have to first multiply 5x2=10 which there are 4 rectangles so you multiply 10 by 4 which gives you 40, next you look at the small squares the lines show that the each side equivalent so to find the area you do 2x2 which gives you 4 and if you have 2 squares it will give you 8 then you add that to the 40 from the rectangles which gives you 48. I hope this helped :))

Use a graph to solve the equation on the interval

artcher [175]

$sec(x)=-\sqrt{2}\qquad 
\begin{cases}
sec(\theta)=\cfrac{1}{cos(\theta)}
\end{cases}
\\ \quad \\
\cfrac{1}{cos(x)}=-\sqrt{2}\implies \cfrac{1}{-\sqrt{2}}=cos(x)
\\ \quad \\
cos^{-1}\left( \cfrac{1}{-\sqrt{2}} \right)=cos^{-1}[cos(x)]
\\ \quad \\
cos^{-1}\left(- \cfrac{1}{\sqrt{2}} \right)=x
\\ \quad \\
\textit{now, check your Unit Circle for those }\measuredangle x$

Simplify the following expressions to simplest form using only positive exponents.

Talja [164]

The equivalent expressions using only positive exponents are 1/(7x⁵y⁸)⁵ and (5y³/x⁶)⁵

<h3>How to simplify the expressions?</h3>

<u>Expression 1</u>

From the question, the expression is given as

(49x¹⁰y¹⁶)⁻⁵/²

Express the radicals as roots

So, we have

(49x¹⁰y¹⁶)⁻⁵/² = √[(49x¹⁰y¹⁶)]⁻⁵

Take the square root of each of the factor in the bracket

This gives

(49x¹⁰y¹⁶)⁻⁵/² = (7x⁵y⁸)⁻⁵

Apply the negative exponent rule of indices

So, we have

(49x¹⁰y¹⁶)⁻⁵/² = 1/(7x⁵y⁸)⁵

<u>Expression 2</u>

From the question, the expression is given as

(125x⁻¹⁸y⁹)⁵/₃

Express the radicals as roots

So, we have

(125x⁻¹⁸y⁹)⁵/₃ = ∛[(125x⁻¹⁸y⁹)]⁵

Take the cube root of each of the factor in the bracket

This gives

(125x⁻¹⁸y⁹)⁵/₃ = (5x⁻⁶y³)⁵

Apply the negative exponent rule of indices

So, we have

(125x⁻¹⁸y⁹)⁵/₃ = (5y³/x⁶)⁵

Hence, the equivalent expression is (125x⁻¹⁸y⁹)⁵/₃ = (5y³/x⁶)⁵
