Answer:
10^12
Step-by-step explanation:
Add the exponents when you multiply numbers with exponents
Using trigonometry
tan(x)=9/6
use your calculator to find x using tan-1(9/6) and you get 56.3° which is basically the first answer
where is the line CA going through
57 or 58 ish
go to the line on the protractor that has 0 at line CB
C(t)=26t^2+168t+4208, and we wish to know when C(t)=15000
26t^2+168t+4208=15000
26t^2+168t-10792=0
They want you to use the quadratic formula...
For a quadratic of the form ax^2+bx+c=0, the quadratic formula is:
x=(-b±√(b^2-4ac))/(2a), in this case we have:
x=(-168±√1122368)/52, since x>0
x≈17.14
1958+17.14≈1975.14
So by 1976 the number of new cars will reach 15000.
Answer: Ten more than twice a number is 34.
Step-by-step explanation:
it would be ten plus 2 times x=34, but we dont know that number, so we replace it with a variable.
2x+10=34
