Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)

Answer:</h3>
- The decrease is Linear.
- The component will cost $84.59 in 3 years
- The decline in price is Exponential.
<h3>
Step-by-step explanation:</h3>
Question 1:
In this question, it's asking you if the decreasing rate is linear or exponential.
The decreasing rate would be <u>linear</u>, due to the fact that it is decreasing at a constant rate of 11%. The decreasing rate doesn't change, which makes this linear.
Question 2:
In this question, it's asking you what would the component's cost be in 3 years if it started off at $120.
To find this, we're going to need multiply the price by -.11, and then subtract to get the price. We would repeat this until we reach 3 years.
Work:
Question 3:
In this question, it asks if the decline in price is linear or exponential.
The decline in price would be <u>exponential</u>, due to the fact that the decrease in price is not always the same, since it changes every year. The price doesn't decrease at the same price each year. As you see from question 2, the change in price is not the same each year.

Answer:
Step-by-step explanation:
g(x)= x - 3
f(x - 3)= (x - 3)^2 - 2
x^2 - 6x + 9 - 2 = x^2 - 6x + 7
b is the answer
Answer:
7.2 times
Step-by-step explanation:
There are 36 possible outcomes when rolling a die twice and adding the results. The outcomes for which the sum is 6 are:
Sum = 6: {1,5; 2,4; 3,3; 4,2; 5,1}
Therefore there is a 5 in 36 chance that the sum will be 6.
The expected number of trials to achieve that result is given by:
On average, it would take 7.2 trials to achieve a sum of 6.
