Juan put three square tiles with sides 8 centimeters, 10 centimeters, and x centimeters together so that they form a right trian

Elan Coil [88]

Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to $x^{2}$ .
$A = x^{2}$ ---> equation (1)
By using pythagoras rule which states that the $x^{2} = hyp^2 - opposite^2$ ---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
$x^{2} = 10^{2} - 8^{2}$ substitute this value in equation (1) then
$A = x^{2} = 10^{2} -8^{2}$
where A is the area of the square whose side is x

Pls helps fast!!

Aleks [24]

Answer:

Option B is correct.

Step-by-step explanation:

We have given a triangle ABC and EDC please look at the figure

We can see that AE and BD are transversal therefore, ∠EAB=∠AED being alternate interior angles

And ∠ACB=∠DCE are vertically opposite angles hence, equal

So, by AA similarity postulate the above to triangles are similar

ΔABC $\sim$ ΔEDC

Therefore, Option B is correct that is Triangle ABC is similar to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5

NOTE: m∠3 = m∠4 corresponds to m∠ACB=m∠DCE

And m∠1 = m∠5 corresponds to m∠EAB=m∠AED

Identify the exponential function graph below. Which of the following is the equation for this graph?

Advocard [28]

Answer:

Step-by-step explanation:

The graph below crosses the y-axis about 2. This means when x = 0, y is about 2. Substitute x = 0 into each equation and solve for y.

$A. f(x)=3^{0}-2\\f(x) = 1 - 2 = -1\\\\B. f(x)=4^{0} -2\\f(x) = 1-2 = -1\\\\C. f(x)=4^{0-2}\\f(x) = 4^{-2} = \frac{1}{16}\\\\D.f(x)=4^{0-2} +2\\f(x) = 4^{-2} + 2 = 2\frac{1}{16}$

D is the solution.
