Find the midpoint of the line segment with the given endpoints: (-1, -6) and (-6, 5).
Vikentia [17]

Answer:

Step-by-step explanation:

First, we will find the midpoint for the x - coordinate first.

Midpoint (x) = \frac{-1+(-6)}{2} \\=\frac{-1-6}{2} \\=\frac{-7}{2} \\=-3.5

Now we will find the midpoint for the y - coordinate.

Midpoint (y) = \frac{-6+5}{2} \\=\frac{-1}{2} \\=-0.5

Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)

An integer from 300 through 780, inclusive is to be chosen at random, find the probability that the number is chosen will have 1
exis [7]

Answer:

  • 93/481

Step-by-step explanation:

<u>Total number of integers from 300 through 780, inclusive:</u>

  • 780 - 299 = 481

<u>Number of integers with at least one of digit 1:</u>

  • Hundreds - 0,
  • Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)
  • Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)
  • So in total 50 + 43 = 93

<u>The probability is:</u>

  • P = favorable outcomes/total outcomes = 93/481

Given the function: f(x) = 2x3 - 3/2x, find f(-4).
Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

f(x) = 2x^3-\frac{3}2x

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\

By using PEDMAS we will solve for exponential function first we get;

Now we know that (-4)^3=-64

So we get;

f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\

Now using PEDMAS we will solve division.

f(-4)= 2\times(-64)-1.5\times(-4)

Now using PEDMAS we solve multiplication.

f(-4)= -128+6

Finally by subtraction we get;

f(-4)= -122

In a right triangle the leg opposite to the acute angle of 30° is 7 in. Find the hypotenuse and other leg.
Maksim231197 [3]
This is a 30-60-90 triangle. 
Therefore, 
7 is A
the other leg is A√3
And the hypotenuse is 2A
So the other leg is 7√3 and the hypotenuse is 14

Log x + log (2x-1) = log 6
Brilliant_brown [7]

Answer:

x = 2

Step-by-step explanation:

logx + log(2x - 1) = log 6

Apply log rules,

x(2x - 1) = 6

2x^2 - 1x = 6

x = 2 (true) or x = -3/2 (False)
