Answer:
Step-by-step explanation:
We must convert the given temperatures from degrees Celsius to degrees Fahrenheit
The formula is:
Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit
Then we must replace the temperature in degrees Celsius and solve the equation for F
The Fahrenheit temperature range in which the antifreeze protects the car is:
The object's maximum height is the same as the y-coordinate of the vertex.To find that, first, finds the x- coordinate(t).You can find it by:
first identifying a,b and c.Multiply the b by negative 1 or simply change its sign and divide it by 2a.Afterward, plug the answer in the equation to find y, your answer.
(ax+bx²+c=-16t²+64t+80). Therefore, a=-6, b= 64 and c=80
-64/2(-16)=-64/-32=2
-16(2)²+64(2)+80=144 ft
So the maximum height of the object, when launched 64ft/sec from a platform that is 80 ft high, is 144 ft
Hope this helps(there are other methods)
