Answer:

7.1

Step-by-step explanation:

5^2 + 5^2 = c^2

25 + 25 = c^2

50 = c^2

7.1 = c

Answer:

B) 7.1 ft

Step-by-step explanation:

Two ways to go about this:

Method 1:

Recognize that since the side lengths are equal to each other, then the hypotenuse must be equal to 5√2 or about 7.1 feet since the triangle is a 45-45-90 triangle.

Method 2:

By using the Pythagorean Theorem, a^2+b^2=c^2, we have 5^2+5^2=c^2 --> 25+25=c^2 --> 50=c^2 --> 7.1≈c

Answer:

The approximate length of segment EF is 7 unit

Step-by-step explanation:

Given figure is the graph having E and F coordinate

The coordinate of point E = ( $x_1$ , $y_1$ ) = ( - 2 , -4 )

The coordinate of point F = ( $x_2$ , $y_2$ ) = ( 2 , 2 )

Let The distance between the points E and F = D

So, D = $\sqrt{(x_2 - x_1)^{2} + ( y_2 - y_1 )^{2} }$

or, D = $\sqrt{(2 - (- 2 ))^{2} + ( 2 - ( - 4 ))^{2} }$

Or, D = $\sqrt{( 4 )^{2} + ( 6 )^{2} }$

or, D = $\sqrt{16 + 36}$

∴ D = $\sqrt{52}$

I.e D = 7.21 unit

So, Approximate value of D = 7 unit

Hence The approximate length of segment EF is 7 unit . Answer

Answer:

The exponents of a start at n and decrease until they reach 0 . The exponents of b start at 0 and increase until they reach n

Step-by-step explanation:

The general formula for $(a+b)^n$ is:

$a^n + C_1a^{n-1}b + C_2a^{n-2}b^2 + ... + C_{n-1}a^2b^{n-2} + C_nab^{n-1} + b^n$

Therefore, the exponents of a start at n and decrease until they reach 0 . The exponents of b start at 0 and increase until they reach n
