F(x)= 2x² -10
f(5)= 2(5)²-10
f(5)= 40
Answer:
this answer is 3 for b i got it right
Answer: Celsius scale
Step-by-step explanation:
Fahrenheit scale is established from the freezing and boiling temperatures of water, which are:
Freezing temperature of water: 
Boiling temperature of water: 
Which means that all temperatures below are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.
Now, 
is in accordance with the high temperatures recorded in the summer season.
If we want to know how much is in Farenheits, we must use the following conversion formula:
The area of a trapezoid is
A = (1/2) h (b1 + b2)
where
h is the height
b1 is length of base 1
b2 is the length of base 2
We are given with the area and assuming that the trapezoid is isosceles, the length of base 1 is
b1 = 4 ft
If the height of the trapezoid is 4.5 feet, it ensures that the shed will fit inside the trapezoid patch of land. Therefore, the height of the trapezoid is 4.5 feet.
