Answer: c)
Step-by-step explanation:
This can be done through trial-and-error. Use the pythagoreas' theorem
and if the left side of the equation is equal to the right, that is the answer.
(Do take note that c is the longest side.)
a)


Since
, a) is wrong.
b)

Since
, b) is wrong.
c) (answer)

Since
, c) is correct.
d)

Since
, d) is wrong.
Again lol. and they were the same age at 3 weeks.
Answer: $8.60
Step-by-step explanation:
Let the price of a bread = x
Let the price of a tarts = x - 1
If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:
3 × x = 1/2 × (1 - x) + 29.5
3x = 0.5 - 0.5x + 29.5
3x + 0.5x = 29.5 + 0.5
3.5x = 30
x = 30/3.5
x = 8.6
Answer:
Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.
As an example, the graph of any function can be parameterized. For, if y = f(x) then let t = x so that
x = t, y = f(t).
is a pair of parametric equations with parameter t whose graph is identical to that of the function. The domain of the parametric equations is the same as the domain of f.
Example The parametric equations
x = t, y = t2
