Answer:

8 units

Step-by-step explanation:

In a 45°- 45°- 90° triangle the legs are congruent, thus

3x - 10 = x + 2 ( subtract x from both sides )

2x - 10 = 2 ( add 10 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Thus

3x - 10 = 3(6) - 10 = 18 - 10 = 8

Since legs are congruent then they are both 8 units

2. Does the set of numbers form a Pythagorean triple? Explain.
nevsk [136]
So Pythagorean triples will always work with Pythagoras theorem which is a^2 + b2 = c^2 where c is the hypotenuse. So the biggest number (15) will be the hypotenuse so you must do (9^2) + (12^2) and if it is a triple you will get 15^2 so you do 81 + 144 which is 255 and 15^2 is 255 so therefore it is a Pythagorean triple because the numbers satisfy the equation. Hope this helps :)

Write a quadratic function h whose zeros are 5 and -7
marin [14]

Quadratic function whose zeros are 5 and -7 is x^2+2x-35=0

Step-by-step explanation:

Write a quadratic function h whose zeros are 5 and -7

If 5 and -7 are zeros of quadratic function then:

x=5 and x=-7

or x-5 = 0 and x+7=0

So, Finding quadratic equation:

(x-5)(x+7)=0\\x(x+7)-5(x+7)=0\\x^2+7x-5x-35=0\\x^2+2x-35=0

So, quadratic function whose zeros are 5 and -7 is x^2+2x-35=0

Suppose that for a certain experiment p​(b​)equals=0.5 and p​(avertical line upper bb​)equals=0.2. find p​(aintersect∩b​).
raketka [301]
P(a | b) = p(a ∩ b)/p(b) . . . . . a definition worth remembering
0.2 = p(a ∩ b)/0.5 . . . . . . . . fill in the given values
0.2*0.5 = 0.1 = p(a ∩ b)

p(a ∩ b) = 0.1

You need to increase this digit because the thousands digit is greater than zero.


The answer is 90,000.
