1.. Find c.<br> please help asap
matrenka [14]

Answer:

10\sqrt{2}

Step-by-step explanation:

The given is a special right triangle with angle measures as follows:

45-45-90

The side lengths for this special right triangle are represented as follows:

a (the side length that sees angle measure 45)

a\sqrt{2} (the side length that sees angle measure 90)

İn the image we can see that one of the side length that sees angle measure 45 is 10

so c, the side length that sees angle measure 90 (hypotenuse),

is equal to

10\sqrt{2}

For each sentence below, find the value of x that makes each sentence true.
vitfil [10]

<u>ANSWER</u>

1. x=\frac{1}{2}


2. x=1


<u>QUESTION 1</u>

The first sentence is (5^{\frac{1}{5}})^5=25^x.


Recall that;

(a^m)^n=a^{mn}


We simplify the left hand side by applying this property to get;


5^{\frac{1}{5}\times 5}=25^x.


\Rightarrow 5^{1}=25^x.


We now rewrite the right hand side too in an index form to obtain;


\Rightarrow 5^{1}=5^{2x}

We now equate the exponents to get;

\Rightarrow 1=2x.


\Rightarrow \frac{1}{2}=x


\Rightarrow x=\frac{1}{2}.


<u>QUESTION 2</u>

The second sentence is (8^{\frac{1}{3}})^2=4^x


We simplify the left hand side first to get;

(2^{3\times \frac{1}{3}})^2=4^x


2^2=4^x


We now rewrite the left hand side too in index form to obtain;


2^2=2^{2x}

We equate the exponents to get;

2=2x


This implies that;


1=x

or

x=1

The area of the rectangle shown is 66m^2
tekilochka [14]

Answer:

143cm

Step-by-step explanation:

Area=2(l+b)

Substitute the values for the variables.

66=2(l+22/5)

66=2xl+2x<u>22</u>

5

66=2l+<u>44</u>

5

Cross multiply

66x5=2l+44

330=2l+44

Collect like terms

-2l = 44-330

-2l = -286

<u>-2l </u>=<u> </u><u>-286</u>

-2 -2

l=143

The missing length is 143m.
