Answer:
889674568890
Step-by-step explanation:
I used a calculator :)
The m BCD would be 25 sorry if wrong!
Sin is equal to opposite over hypotenuse
With this we know that
Opposite = sqrt(12)
Hypotenuse = 4
To find adjacent we need to use the Pythagorean theorem
12 + adj^2 = 4^2
We then solve for adj
12 + adj^2 =16
adj^2 =4
adj =2
Now that we have opposite, adjacent, and hypotenuse, we can find cos and tan
Cos is equal to adj/hypotenuse
Cos = 2/4 = 1/2
Tan is equal to opp/adj
Tan = sqrt(12)/2
Answer:
f(-2)=-4
Step-by-step explanation:
To solve this, simply plug the value into the function as follows:
f(-2)=(-2)^2+3(-2)-2
f(-2)=4-6-2
f(-2)=-4
