Substitute x= 3 and calculate
f(3)= 2•9+5• sqrt( 1)
f(3)= 18+5= 23
Answer:
Im pretty sure its c
Step-by-step explanation:
Diameter be d
Radius be r
- πr²=6767
- r²=6767/π
- r²=2155
- r=46.4cm
Diameter=2r=46.4(2)=92.8cm
Answer:
1 solution
Step-by-step explanation:
A system of linear equations has no solution when the graphs are parallel.
Answer:
x=15
Step-by-step explanation:
So we know 4x plus 8x gets a total of 180 degrees (since a straight line is 180 degrees). Combine 4x and 8x to get 12x. To find x, divide 12 from 180. 180/12 is 15.
