What is the product of 6+5i and 4+7i?

Mathematics

(6 + 5i)(4 + 7i) = 24 + 42i + 20i + 35i²
= 35i² + 62i + 24

The product of 6+5i and 4+7i is 35i² + 62i + 24.

A given line has the equation 10x + 2y = −2.
stepladder [879]
10x + 2y = -2

2y = -10x -2

y = -5x - 1 (slope is -5 and a parallel line will have the same slope)


y = mx + b

slope(m) = -5

12 = -5(0) + b

12 = 0 + b

12 = b

so the parallel line is y = -5x + 12

hope this helps, God bless!

Graph a right triangle with the two points forming the hypotenuse. Using the sides, find the distance between the two points in
pshichka [43]

Answer:

d=\sqrt{53}

Step-by-step explanation:

We need to find the distance between two points i.e. (−5,−1) and (−3,−8).

It can be calculated using distance formula as follows :

d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

We have, x₁ = -5, x₂ = -3, y₁ = -1 and y₂ = -8

Put all the values,

d=\sqrt{(-8-(-1))^2+(-3-(-5))^2}\\\\d=\sqrt{49+4}\\\\d=\sqrt{53}

So, the distance between the points is equal to \sqrt{53}

The mean of a population being sampled is 64, and the standard deviation is 6. If the sample size is 50, the standard error of t
Serjik [45]
Given:
mean = 64
standard deviation = 6
sample size = 50

Standard error of the sample mean = standard deviation / √sample size

Standard error = 6 / √50 = 6/7.07 =<span> 0.85</span>
