Answer: 0.75
Step-by-step explanation:
We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.
We now have a triangle with the values of:
x = 4
y =3
h^2= 4^2 + 3^2
h^2 = 16 + 9
h^2 = 25
h = 5
h = 5
Tangent = opposite/adjacent
= y/x
= 3/4
= 0.75
Answer:
B
Step-by-step explanation:
The solution is the point of intersection, which is (-1, 3)
Answer:
13x-9
Step-by-step explanation:
9×(x - 1)
9x - 9 +4x
collect like terms, 9x+4x=13x
Using proportions, it is found that the original sample weighed 
grams.
- This question is solved by <em>proportions</em>, using a rule of three.
- The weight of 1 batch, in grams, is of
. How much do the sample of 12 batches weigh?
The rule of three is:
1 batch - grams.
12 batches - x grams
Applying cross multiplication:
Applying scientific notation:
The original sample weighed grams.
