Answer:
13. For every 5 wolves there are 3 cougars in a forest
4. You and your friend are not traveling at the same pace; your friend is traveling faster
Step-by-step explanation:
4. set same denominator
63/12
21/3 = 21*4 3*4 = 84/12 (your friend)
84/12 is traveling faster
The geometric mean of 8 and 12 is approximately 9.79796
Answer: x + 7y = 12
Explanation:
The question is: "I<span>ndicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"
</span>
1) The standard form of the equation of the line passing through two points is:
Ax + By = C
2) You can find the equation of al line given two points in a two stages process:
i) Find the slope:
slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7
ii) set the point slope equation:
y - y₁ = m [x - x₁]
y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)
⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7
⇒ x + 7y = 12

Answer:
1975------ 4.8%
1990 ------ 11.48%
1985 ------ 8.51%
Step-by-step explanation:
Given
if 0 ≤ t < 10
if 10 ≤ t ≤ 30
Where
t:=0 implies year = 1970
Solving (a): Beginning of 1975.
First, we calculate the value of t
This falls in the range: 0 ≤ t < 10
So:
Solving (b): Beginning of 1990.
This falls in the range: 10 ≤ t ≤ 30
So:
Solving (c): Beginning of 1985
This falls in the range: 10 ≤ t ≤ 30
So:
