Length AC
A(-3,-3), C(3,2)

d= (3-(-3))^2 + (2-(-3))^2
d= (6)^2 + (5)^2
d= 36+ 25
Square root 61 = 7.8

Length AC = 7.8


Length BC
B(1,-2) , C(3,2)

d= (3-1)^2 + (2-(-2))^2
d= (2)^2 + (4)^2
d= 4+ 16
Square root 20 = 4.5

Length BC= 4.5

Hope this helps!

Pythagorean theorem level 2 delta math
julsineya [31]

The third side is 4

So Pythagorean's theorem is the following

Short^2 + Long^2 = Hypotenuse^2

From here we can input the following information that we know

Short^2 + \sqrt{33}^2 = 7^2\\Short^2 + 33 = 49\\Short^2 = 49 - 33\\Short^2 = 16\\Short = \sqrt{16}\\Short = 4

A group of marketing students at a large university wants to determine the proportion of first year students who use certain typ
GREYUIT [131]

The required sample size is 694.

Given a student wants to make a guess within 0.03 of the true ratio with a 95% confidence level.

Margin of Error, E = 0.03

significance level α=0.05  {95% confidence}

A given estimate of the percentage of population p is p = 0.79.

The critical value for the significance level α = 0.05 is Zc = 1.96. This can be determined using either Excel or a normal probability table.

Use the following formula to calculate the minimum sample size required to estimate the percentage of population p within the required margin of error.

n≥p(1-p)(Zc÷E)²

n=0.796×(1-0.796)(1.96÷0.03)²

n=693.1016

Therefore, the  resample sizequired to meet the condition is n ≥ 693.1016 and must be an integer. From this, we conclude that the minimum sample size required is n = 694.

y = –6x 2 –12x – 2y = –4 how many solutions does this linear system have? one solution: (0, 0) one solution: (1, –4) no solution
lara [203]
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4

Therefore, the system has infinite number of solutions.
