Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -5x - 2
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = -5(3) - 2
- Multiply: f(3) = -15 - 2
- Subtract: f(3) = -17
Answer:
g(x)=10x-30 when x is 1
g(x)=-20. hence dats is d first function
g(x)=-20x+5
g(x)=-15 hence dats d second function
Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ]
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus
average rate of change = 
= 
= 34
Answer: Half of a ton equals to 1,120 pounds.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Since 80 stones make up half of a long ton, and each stone weight is 14 pounds, to obtain the number of pounds in half of a long ton we simply have to multiply the number of stones (80) by the weight of each stone (14)
Mathematically speaking:
<em>14 x 80 = 1,120 pounds
</em>
Half of a ton equals to 1,120 pounds.
Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 
. Therefore, an equiangular triangle will have each of its angles equal to 
. We can then set up the following equation:
.
