Answer:
Step-by-step explanation:
Given triangle ABC is a right triangle.
m∠ACB = 60°
m∠CAB = 30°
m(AC) = 1 unit
A). Shorter side of the given triangle = Side BC
By applying cosine rule,
cos(∠C) =
cos(60°) =
BC =
BC =
Length of the shorter side = 0.5 units
B). Longer side of the given triangle = side AB
By applying Pythagoras theorem in the given triangle,
AC² = AB² + BC²
1² = AB² +
1 = AB² +
AB =
AB =
AB =
Length of the longer side =

Answer:
3 significant digits
Step-by-step explanation:
If there is a decimal point with non-zero digits to its left, all digits to the right of the left-most non-zero digit are significant. Here, that is all of them. This number has 3 significant digits.
__
<em>Comment on other cases</em>
If there is no decimal point, the digits between any leading and trailing zeros are significant. For example, 02000 has 1 significant digit.
If there are no non-zero digits left of the decimal point. All digits except leading zeros are significant. 0.0031000 has 5 significant digits.
Answer:
f(h(x)) = x
h(f(x)) = x
Step-by-step explanation:
f(x) = 8x-7
h(x) = x+7/8
We need to find f(h(x)) and h(f(x))
Finding f(h(x))
Putting value of h(x) into f(x) i.e
f(h(x)) = 8(x+7/8)-7
f(h(x)) = x+7-7
f(h(x)) = x
Now finding h(f(x))
h(f(x)) = (8x-7)+7/8
h(f(x)) = 8x-7+7/8
h(f(x)) = 8x/8
h(f(x)) = x
