Gemma wants to draw a triangle with side lengths of 4 inches, 12 inches, and 17 inches. Which statement is true?

Answers

Answer: The triangle is impossible due to triangle inequality theorem

Step-by-step explanation:

Triangle inequality theorem states that the sum of side lengths of any two sides of a triangle must be greater than the length of the third side. Since 4 + 12 < 17, then this triangle cannot exist.

Answer:

This triangle does not exist because the sum of 4 and 12 is less than 17.Step-by-step explanati

Well..They gave you the hint all you have to do is apply the formula

hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]

So lets do this

axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

Answers

Answer:

use 2 defined points.

Lets use: (-3,0) and (0,3)

The equation is written as y = mx+b, where m is the slope and  is the y-intercept

Slope - change in y / change in x:

Slope = (3 -0) /(0- -3) = 3/3  = 1

b is the y-intercept which is the y value when x is o, which is one of the points (0,3) so b = 3

The equation becomes y = x +3

Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

The value of a car with an initial purchase price of $12,250 depreciates by 11 percent per year

Answers

Answer:

It is decay  because the value of the car keeps falling.

for example, the value next year, would be 12250 x (100% - 11%) = $10,902.50

If it were a growth, the value would increase yearly

12250 x (0.89)^time

Step-by-step explanation:

the equation to represent exponential decay = Amount x ( 1 - rate)^time
