Answer:

1/8

Step-by-step explanation:

The slope of a line given two points is found by

m = (y2-y1)/ (x2-x1)

   = (-2 - -3)/(4 - -4)

   = (-2 +3)/(4+4)

    1/8

\text{Use the slope formula:}\\\\\frac{y2-y1}{x2-x1}\\\\\text{Plug in coordinates and solve:}\\\\\frac{-2+3}{4+4}\\\\\frac{1}{8}\\\\\text{Since you can't simplify any further, that concludes your answer}\\\\\boxed{\frac{1}{8}}

The length of one leg of a right triangle is 8 centimeters shorter than the
ra1l [238]

{34}^{2}  +  {b}^{2}  = {42}^{2}  \\ 1156 + {b}^{2}  = 1764 \\ 1156 - 1156 +  {b}^{2}  = 1764 - 1156 \\  {b}^{2}  = 608 \\  \sqrt{ {b}^{2} }  =  \sqrt{608}  \\ b = 24.7
I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.

What is the answer for 4i over 3+7i
icang [17]

Answer:

see explanation

Step-by-step explanation:

given \frac{4i}{3+7i}

To rationalise multiply the numerator/denominator by the conjugate of the denominator

the conjugate of 3 + 7i is 3 - 7i, hence

\frac{4i(3-7i)}{(3+7i)(3-7i)}

distribute the numerator/denominator

= \frac{12i-28i^2}{9-49i^2}

[ note that i² = - 1 ]

= \frac{12i+28}{9+49}

= \frac{28+12i}{58}

= \frac{28}{58} + \frac{12}{58} i

= \frac{14}{29} + \frac{6}{29} i ← in standard form

At a gymnastics competition, Joey scored 9.4, 9.7, 9.9, and 9.8. Carlos scored 9.5, 9.2, 9.7, and 9.6. Who had the greater avera
8090 [49]
You got add all the numbers up and divide it by how many numbers there are to get the average.
9.4 +9.7 + 9.9 + 9.8 = 38.8 divided by 4 =9.7 is Joey's average.
9.5 +9.2 +9.7 +9.6 =38 divided by 4 = 9.5 is Carlos' average.
Joey has more average by 0.2.
