7 in the expression above represents a factor because after adding 3 and 13, you would need to multiply 2 and 5. Then, you will multiply 7 and 16 which shows that 7 in the expression above represents a factor.
14* 6=84 , sorry for the delay enjoy your day!
Answer:
The equation which describe this function is 5x + 11y = 37
Step-by-step explanation:
<u>To find the slope</u>
slope = (y₂ - y₁)/(x₂ - x₁)
slope = (13 - 2)/(-2 - 3) = 11/-5
<u>To find the equation</u>
(x - 3)/(y - 2) = -11/5
5(x - 3) = -11(y - 2)
5x -15 = -11y + 22
5x + 11y = 22 + 15
5x + 11y = 37
Therefore the equation which describe this function is
5x + 11y = 37
Answer:
Area = 16π
Step-by-step explanation:
Area of a circle = πr^2
= 64π
= sqrt64
r = 8 because 8 × 8 is 64
Radius = 8
Now, use the circumference equation:
= 2πr
= 2π(8)
= 16π
S(t) = 3.82 - 0.2t
Step-by-step explanation:
After 7 weeks, the ice is 2.42 meters thick. The ice loses 0.2 meters of thickness per week; this means on the 7th week, it has lost 7(0.2) = 1.4 meters of thickness.
This means the ice started at 2.42+1.4 = 3.82 meters thick.
Our function will start at the original thickness of the ice, 3.82 meters.
Since the ice is losing thickness, we will subtract; it loses at a rate of 0.2 meters per week (t), which gives us 0.2t. This is subtracted from the original, 3.82 meters, giving us
S(t) = 3.82 - 0.2t
