800 + 60 + 3 + 0.1 + 0.04 + 0.001
That's 863.141 in expanded form.
Answer:
a) The average global surface temperature in 2100 is 10.7°C
b) b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).
Step-by-step explanation:
T = 0.01t + 8.7
To predict the temperature of the planet in the year 2100.
We will calculate the number of years that 2100 is, since 1900
t = 2100 - 1900 = 200 years
T = (0.01 × 200) + 8.7 = 10.7°C
The average global surface temperature in 2100 is 10.7°C
b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).
Answer:
-8.05
Step-by-step explanation:
In order to solve for C you first have to subtract 17.6 from both sides.
2c=(6/4)-17.6
6/4 is 1.5
1.5-17.6=-16.1
2c=-16.1
c=-8.05
Hi again
x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.
If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.
Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8
I hope that's help !
