Some scientists believe that the average surface temperature of the world has been rising steadily. they have modeled the temperature by the linear function t = 0.01t + 8.5, where t is temperature in °c and t represents years since 1900. (a) what do the slope and t-intercept represent? the slope is , which means that the average surface temperature of the planet is at a rate of °c per year. the t-intercept is , which presents the average surface temperature in the year . (b) use the equation to predict the average global surface temperature in 2050. °c

A.

The slope is positive and means the temperature is increasing since year 1900

T interception is 8,5 and it is the temperature in the year 1900

B. 29°C

Step-by-step explanation:

The function is the kind y=mx+b then we can see the "b" represents the value of "y" with the horizontal line in the graph, it means when x=0

the m is the slope and for our function is 0,01 and it is a positive number, in a graph a positive slope represents a line always increasing.

For the b

We just have to substitute the t with the value 2050 in the funtion

T=0,01(2050)+8,5

The result is 29°C

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
