If the lengths of two sides of a triangle are 5 and 9, respectively, which of the following could be the length of the third side of the triangle? Indicate all such lengths. [A] 3 [B] 5 [G] 8 [D] 15

Answers

Answer 1
Answer:

Final answer:

According to the triangle inequality theorem, the third side of a triangle, given the other two sides, must be greater than the absolute difference and less than the sum of those sides. In this case, given sides 5 and 9, the possible third sides are 5 and 8.

Explanation:

In Mathematics, particularly in the field of geometry, the triangle inequality theorem states that the length of one side of a triangle is always less than the sum of the lengths of the other two sides but more than the absolute difference of those lengths.

Given the lengths of two sides of the triangle are 5 and 9 respectively, the possible lengths of the third side are anything greater than 4 (9 - 5) and less than 14 (9 + 5). So among the choices given: [A] 3, [B] 5, [G] 8, [D] 15; only [B] 5 and [G] 8 could be the length of the third side of the triangle.

Answer 2
Answer:

Final answer:

In the triangle with sides 5 and 9, according to the triangle inequality theorem, the length of the third side must be between 4 and 14. Therefore, from the given options, only 5 and 8 could be the lengths of the third side.

Explanation:

To find possible lengths for the third side of a triangle when lengths of two other sides are given, we can adhere to the triangle inequality theorem. This theorem states that the length of any side of a triangle must be less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.

In this case, the given lengths are 5 and 9. So the possible length of the third side (let's denote it as x) should obey to: |5 - 9| < x < 5 + 9, that is 4 < x < 14.

Therefore, from the given options, [B] 5 and [G] 8 could be possible lengths for the third side of the triangle.

the equation of line AB is y = -1/4 x - 2. write an equation of a line parallel to line AB in slope intercept form that contains point (-3,2)

Answers

The general equation of a straight line is in the form of;
Y=MX + c,
Where m is the gradient and
C the y-intersept.
Parallel line have the same gradient.
From the equation,
Y=-1/4X - 2,
Gradient = - 1/4.

Now assuming that the second line passes through (x,y) and (-3,2).
(Y-2)/(X--3) =-1/4
4(Y-2)=-1(X+3)
4Y-8 = -X-3
4Y = -X -3+8
4Y = -X +5
Y = -1/4X +5/4
Answer: y = -(1/4)x + 5/4

Explanation:

1) Parallel lines have equal slopes.

2) The slope-intercept form of the equation of the line is y = mx + b, where m is the slope and b is the y-intercept.

3) Hence, the slope of the given equation, i.e. y = (-1/4)x - 2 is m = -1/4

4) Therefore, that is the same slope of any line parallel to it, m = -1/4

5) The slope-point equation of the line is:

y - y₁ = m (x - x₁)

6) Now you replace -1/4 for m, and the point (-3,2)

⇒ y - 2 = [ -1/4) (x - (-3) ]

7) Expand the product and simplify:

y - 2 = -x/4 - 3/4
y = -x/4 -3/4 + 2
y = -x/4 + 5/4

And that is the equation requested

Answers

Answer:B the amount of money in a bank account never changes.

Step-by-step explanation:

Answer:

B. The amount of money in a bank account never changes.

Step-by-step explanation:

Equilibrium is achieved when the state of a reversible reaction of opposing forces cancel each other out. While in a state of equilibrium, the competing influences are balanced out. Imagine a cup with a hole in it being filled with water from a tap. The level of water in this cup would stay the same if the rate at which the water that flows inside is the same as the water that flows outside. Option B will be the correct answer because the amount of money going into the account is at the same rate of money coming out of the account.
