Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
Answer:
A=23512.32
Step-by-step explanation:
The equation for the area of a cylinder is A=2πrh+2πr^2
If we substitute the radius and height, the equation would be A=2π(60)(2.4)+2π(60)^2
π can be shortened to 3.14 so it's A=2(3.14)(60)(2.4)+2(3.14)(60)^2
We're left with 904.32+22608
So the answer is 23512.32
3,256,423,865 rounded to the nearest million is 3,256,000,000. How I know is that the 4 in the hundred thousands place is lower than 5. So the 6 would of stayed the same and the rest of the number behind 4 would of been 0, including the 4.
Answer:
x=-4
Step-by-step explanation:
2(|x+4|+3)=6
take out absolute value
2(x+4+3)=6
remove parrenthesis
2x+8+6=6
Simplify
2x+14=6
-14 -14
2x=-8
x=-4
Hope this helps!!!!!
