y=22
Answer:
Slope : The rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.
T-intercept : 8.5 represents the temperature in °C of the earth's surface in the year 1900.
Step-by-step explanation:
The average surface temperature of Earth rising steadily. Scientists have modeled the temperature by the equation, T = 0.02t + 8.50 where t represents years since 1900 and T is the temperature in ◦C.
Now, the slope of the model equation is 0.02 which means the rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.
Again, the T-intercept i.e. 8.5 represents the temperature in °C of the earth's surface in the year 1900. (Answer)
Answer:
Part 1) The length of two sides and the measure of the included angle (Side-Angle-Side)
Part 2) 
Part 3) 
Step-by-step explanation:
we have
In the triangle ABC
Part 1) Which information about the triangle is given?
In this problem we have the length of two sides and the measure of the included angle (Side-Angle-Side)
see the attached figure to better understand the problem
Part 2) Which formula can you use ti find b?
I can use the law of cosines
we have
substitute the given values
Part 3) What is b, rounded to the nearest tenth?
Remember that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than 
(this is called rounding down)
c) But increase it by 
if the next digit is or more (this is called rounding up)
In this problem we have
We want to keep the digit
The next digit is 
which is 5 or more, so increase the "5" by 1 to "6"
therefore
Answer:
A) x^2-10x+25 B)X^3-15x^2+75x-125
Step-by-step explanation:
H^2=(x-5)(x-5)=x^2-10x+25
H^3=(x-5)(x-5)(x-5)=X^3-15x^2+75x-125
Answer:
5/162
Step-by-step explanation:
There's a 5/9 chance that you spin an odd and a 1/2 chance you get heads and a 1/9 chance you get a 3 on the spinner multiply the fractions together and get 5/162.
