#27 specifies: g(x)=2x h(x)=x^2+4
(h°g)(1) means do y = g(1) first then find h(y). So: y = g(1) = 2*1 = 2; h(y) = 22 + 4 = 8 i.e. (h°g)(1) = 8
Try the same method with the others. Note that for #30 you need to set y = h(-2), then find g(y).
The quotient is the result of dividing one number by another, so your quotient is 422.0875 (which is 337.67/0.8)
What do you want to do with this?
Expand it as (4479*777 + 4479*x)/11 = (3480183 + 44798x)/11 ?
Separate the terms (3480183/11) + (44798/11)x ?
Approximate in decimal form 316380.3 + 4072.5x ?
...?
You can use the calculator here: http://web2.0calc.com/ to do this.
The calculator here doesn't automatically round to a specific number of decimal places. However, it should be easy to do this by hand. For example:
2.71828 becomes 2.718
3.14159 becomes 3.142
etc.
It is unclear what you are asking for here. Do you mean
(i) 4268*log(943)*7
(ii) 4268*log(943*7)
(iii) log(4268)*943*7
(iv) ...?
Percent means out of 100, so 1 in every 4 means (1/4)*100 = 25%
√(7 - y) = 6
Square both sides:
7 - y = 36
Add y to both sides:
7 = 36 + y
Subtract 36 from both sides:
-29 = y or just y = -29.
Check in the original equation:
√(7 - (-29)) = √(7+29) = √36 = 6 ok.
You can't, unless you have at least one side length! There are an infinite number of similar triangles with the same three angles - they are just different sizes.
Because there are 60' in one degree and 3600" in one degree you can enter your angle as (48 + 30/60 + 24/3600)°.
