The converse of the statement would be
"If x ≤ 7, then x² ≤ 49"
but this is false. Take x = -8; while it's true that -8 ≤ 7, the second inequality is not, since (-8)² = 64 is not smaller than 49.
(i) Given that

when
this reduces to






(ii) Differentiate
implicitly with respect to
. By the chain and product rules,

(iii) Differentiating both sides of the given equation leads to

where we use the result from (ii) for the derivative of
.
Solve for
:





From part (i), we have
and
, and substituting these leads to



as required.
Answer: 5.37 as a mixed number is 5 37/100
To write a decimal number as a mixed number, you must separate the whole part of the decimal part:
5.37 = 5 + 0.37 = 5 0.37
And express the decimal part as a fraction:
0.37=37/100
Then:
Answer: 5.37 as a mixed number is 5 37/100
Answer:
The answer to the equation -8t^2+16t = -48
Step-by-step explanation:
Add ''-8t^2'' to ''16t'' and the answer you get is ''-48''
