Answer:
For question 5 the correct formula is C=πd
For question 6 the correct formula is C=2πr
For question 7 the answer is 56.52 I think I'm not 100% sure though
For question 8 the answer is 31.4
Step-by-step explanation:
The only solution for
is
, so it's either
or
.
Both
and
are equal to 1, so the answer is
.
0.04x10^5
move decimal 5 TIMES TO THE RIGHT.
0.04000
12345
4000
I hope this helps;)
Answer:
the answer is -30 so the final answer is - 30
I assuming by "solve the equation" you mean I have to find the zeroes of this equation
(i.e the values of x which satisfy this equation). For that any one of the factor value must be equal to 0 so that when it will multiply with other factors it will make the left hand side equal to right hand side giving us one of the possible solutions. Since there are 10 different factors there will be 10 different solutions here to x.
they are:
(in order of the factors mentioned in the question)
(i)
(ii)
(iii)
(iv)
x+2=0
x=-2
(v)
x-7=0
x= 7
(vi)
x+3=0
x=-3
(vii)
x-9=0
x=9
(viii)
x+7=0
x=-7
(ix)
(x)
