Answer:
sqrt(170) or approximately 13.038
Step-by-step explanation:
We can use the Pythagorean theorem to find the diagonal since the diagonal makes a right triangle
a^2 + b^2 = c^2
We need to find the leg lengths
ML = 7 and MJ = 11
7^2 + 11^2 = JL^2
49+ 121 = JL ^2
170 = JL ^2
Take the square root of each side
sqrt(170) = JL
13.038 = JL
To do this, firstly convert the fraction to a decimal, then multiply it by 100 (the same way you would to get your percentage in a test.).
16/75 = 0.213 to 3sf
Then multiplying that we get 16/75 is 21.3%
Answer:
c
Step-by-step explanation:
Answer:
(a) is a real number as the answer is -3
(b) is not a real number as the answer is an imaginary number
Step-by-step explanation:
For (b), when you root a negative number, you will get an imaginary number which is not a real number
Answer:
[(sec^2)(x)]. [e^tan(x)]
Or
[e^(tan(x))]/[(cos^2)(x)].
Step-by-step explanation:
d/dx(e^tan(x))
From the low:
[(d/du)(e^u)]=[(d/du)(u)]. [ln(e)]. [e^u]
=[(sec^2)(x)]. [e^(tan(x))]. [ln(e)]
=[(sec^2)(x)]. [e^(tan(x))]
or
[e^(tan(x))]/[(cos^2)(x)].
Because
(cos^2)(x)=1 / (sec^2)(x)
