Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Pa
Misha Larkins [42]

Answer:

A yes, B no

Step-by-step explanation:

The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.

A Given 21, 18, 17 , then

21 + 18 = 39 > 17

21 + 17 = 38 > 18

18 + 17 = 35 > 21

Thus the triangle could exist

B Given 3, 12, 8 , then

3 + 12 = 9 > 8

3 + 8 = 11 < 12 ← fails the test

Thus the triangle does not exist

Choose the property used to rewrite the expression.
Alex73 [517]

The property used to rewrite the given expression is product property.

Answer: Option A

<u>Step-by-step explanation:</u>

Given equation:

                          \log _{2} 10+\log _{2} 4=\log _{2} 40

The sum of the two logarithms of two quantities (on the same basis) corresponds to the logarithm of their product on the same basis. The product log is equal to the log’s sum of the factors.

                                \log _{b}(x \times y)=\log _{b} x+\log _{b} y

There are several rules that you can use to solve logarithmic equations. One of these guidelines is the logarithmic products rule that you can use to differentiate complex protocols in different ways. Different values that can be valuable are the quota principle and the logarithm rule. The logarithmic products rule is essential and is regularly used in analysis to control logs and simplify baseline conditions.

Can someone help please I need help
mina [271]

Answer:

C= 25n+100

Step-by-step explanation:

Let's see what's in the graph :

  • the image of 4 is 200 C(4)=200
  • C(2)= 150

let m be the slope of this function :

  • m= \frac{200-150}{4-2}=25

The first value in the graph is 100 wich is c(0)=100

  • so the equation is : c=25n+100
