7 0

all of them will give u zero

but not all of them

in the first one only if you equate x to be 3 that is when it will give u zero

for the second one is only when u equate x to be seven that's when it will be equal to zero

the same thing for the rest!

Classify ABC by its sides. Then determine whether it is a right triangle.

m_a_m_a [10]

Answer:

∴Given Δ ABC is not a right-angle triangle

a= AB = √45 = 3√5

b = BC = 12

c = AC = √45 = 3√5

Step-by-step explanation:

Given vertices are A(3,3) and B(6,9)

$AB = \sqrt{x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} }$

AB = $\sqrt{(9-3)^{2}+(6-3)^{2} } = \sqrt{6^{2}+3^{2} } =\sqrt{45}$

Given vertices are B(6,9) and C( 6,-3)

$B C = \sqrt{x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} }$

= $\sqrt{(-3-9)^{2}+(6-6)^{2} } =\sqrt{12^{2} } = 12$

BC = 12

Given vertices are A(3,3) and C( 6,-3)

$AC = \sqrt{(6-3)^{2}+(-3-3)^{2} } = \sqrt{9+36} = \sqrt{45}$

AC² = AB²+BC²

45 = 45+144

45 ≠ 189

∴Given Δ ABC is not a right angle triangle

1) Find the mean of this data set. 4, 8, 6, 5, 4, 3 * 20 points 3 4 5 6

damaskus [11]

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

Start by adding the numbers to get 30.

Now, divide by the number of numbers in the set.

So we have 30 ÷ 6 which is 5.

So the mean is 5.
