Step-by-step explanation:
everything can be found in the picture
two times a number n plus three
Answer:
See below
Step-by-step explanation:
The derivative of the function is the slope
2x^2 - x -1 take derivative ( f ' )
4x -1 equate to 7
7 = 4x -1
x = 2 sub into the original equation to find y = 5
Answer:
The range in temperature is 62° F
Step-by-step explanation:
The range is simply the difference between the highest and the lowest temperature recordings on that particular month.
We obtain the difference between 80 and 18;
80 - 18 = 62
The range in temperature is thus 62° F
Answer:
4/3 litres of water is enough to water 2/5 of the plants
Assuming the number of plants in the house is an unknown variable, take the value as x.
Thus, 4/3 litres is enough to water 2x plants in the house.
x = 4/3 ÷ 2
= 2/3 litres
Amount of water for all the plants = 5x = 5 × 2/3
= 10/3 litres
Thus, 10/3 litres of water is necessary to water all the plants in the house.
