Answer:
f(-1) = 11
Step-by-step explanation:
f(x) = 2x^2 - 6x + 3
Let x = -1
f(-1) = 2(-1)^2 -6(-1) +3
=2*1 +6 +3
=2+6+3
= 11

Hey there! I'm happy to help!
First, let's find the radius. The radius is half of the diameter.
8.4/2=4.2
Here's how to find the area of a circle.
Square the radius.
4.2²=17.64
And multiply by pi (3.14 in our case)
17.64(3.14)=55.3896
We round to the nearest tenth, giving us an area of 55.4 ft²
Have a wonderful day! :D
Answer:
Actual probability or experimental probability is the name of the "other" type of probability.

Yet in actuality, if you run an experiment you won't always get that theoretical result.
Answer: ?Once you find the value of your angle, subtract it from 180° to find the possible second angle. Add the new angle to the original angle. If their sum is less than 180°, you have two valid answers. If the sum is over 180°, then the second angle is not valid??????
