Answer:

Below in BOLD.

Step-by-step explanation:

1. x^2 = 3^2 + 6^2

x^2 = 9 + 36 = 45

x = √45

x = 3√5.

2. 15^2 = x^2 + 12^2

x^2 = 15^2 - 12^2 = 225 - 144 = 81

x = 9.

9, 10 and 15 are Pythagorean triplets.

3. x^2 = 10^2 - 6^2 = 64

x = 8.

6, 8 and 10 are Pythagorean triplets.

Is (4, -2) the solution of the system of equations shown

Advocard [28]

No, because if you substitute (4, -2) into x and y in each equation, they are not the same as the value on the right side of the equation.

2(4) + 4(-2) = - 2

8 + -8 = -2

0 = -2 <---- this is not correct.

-4(4) + -2 = -14

-16 + -2 = -14

-18 = -14 <----- this is not correct.

If f ( 4 ) = − 2 , write an ordered pair that must be on the graph of y = f ( x + 4 ) + 1

AlekseyPX

We have been given that

$y = f ( x + 4 ) + 1\\
\\
f(4)=-2$

Now, we need to find an ordered pair that must be on the graph of

$y = f ( x + 4 ) + 1$

On substituting x=0 in the above equation, we get

$y = f ( 0 + 4 ) + 1\\
\\
y=f(4)+1\\
\\
\text{On substituting the value of f(4)= -2, we get}\\
\\
y=-2+1\\
y=-1$

Therefore, the required ordered pair is given by (0,-1)

Answer:

The length of diagonal d is 14.1421 cm

Step-by-step explanation:

We are given square

Length of side of square = 10 cm

We need to find the length of diagonal d

To find diagonal of square, the formula used is:

$Diagonal\: of\: square=s\sqrt{2}$

where s is length of side of square.

Putting values of s and finding length of diagonal of square

$Diagonal\: of\: square=s\sqrt{2}\\Diagonal\: of\: square=10\sqrt{2}\\Diagonal\: of\: square=10(1.41421)\\Diagonal\: of\: square=14.1421\:cm$

So, The length of diagonal d is 14.1421 cm
