Answer:
The scale factor is 3
Step-by-step explanation:
The width of A is 1, the width of B is 3
the length of A is 3, the length of B is 9 so the scale factor from A to B is 3
Answer:
= 45 miles per hour
Step-by-step explanation:
First, we want a unit rate where 1 is in the denominator.
So we divide,
180 miles/ 4 hours both ÷ by 4
= 45 miles/ 1 hour
= 45 miles/ hour
= 45 miles per hour
Answer:
-1
Step-by-step explanation:
y = -x + 6 the number in front of x is the point slope
so, the answer is -1 because the number in front of x is -1
Answer: 85°
Step-by-step explanation:
Trig functions are remembered by
SOD CAD TOA,
sin = opposite / distance, cos = adjacent / distance, and tan = opposite / adjacent.
Here we have the adjacent side = 100, opposite side = 1058. The tower would fall over if it weren't vertical, and we assume the area is flat and level. So tangent of the answer is 10.58.
We need the angle whose tangent is 10.58.
On Android calculator you swipe left to get the trig functions, tap INV, if RAD is showing tap it to change it to DEG, and tap tan⁻¹. Swipe right and you see tan⁻¹(. Enter 10.58 and the result shows 84.6005606. If it shows 1.47655833 tap the RAD in upper left to change to DEG.
Answer: The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%.
