Answer:
Difference between average day temperature and average night temperature = 70°
Step-by-step explanation:
Given;
Average day temperature = 43° C
Average night temperature = -30° C
Find:
Difference between average day temperature and average night temperature
Computation:
Difference between average day temperature and average night temperature = Average day temperature - Average night temperature
Difference between average day temperature and average night temperature = 43 - (-30)
Difference between average day temperature and average night temperature = 70°
Answer:
D: 7
Step-by-step explanation:
1.75 (7) + 4.50
12.25 + 4.50
= 16.75
16.75 < 20
Answer: 21
Step-by-step explanation:4/4=1 5x4=20 20+1 = 21
Important: indicate exponentiation with " ^ "
Thus, x = ( y - 4 )2 + 27 becomes <span>x = ( y - 4 )^2 + 27
This can be re-written as x = y^2 - 8y + 16 + 27, or x = ay^2 - 8y + 43. This is the equation of the parabola in standard form x = ay^2 + by + c.</span>
