Answer:
Option D
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:
b^2 = a^2 + c^2 - 2*a*c*cos(B).
The question specifies that a=42, B=120°, and c=35. Plugging in the values:
b^2 = 42^2 + 35^2 - 2(42)(35)*cos(120°).
Simplifying gives:
b^2 = 4459.
Taking square root on the both sides gives b = 66.78 (rounded to the two decimal places).
This means that the length of the third side is 66.78 units!!!
Well, if we see the graph of x^2
the vertex is (0,0)
if we reflect it acrosss the x axis, teh vertex is still (0,0)
verteical strech doesn't change the vertex
vertex of g(x) is same as f(x)
first answer
The inequality to describe the situation is; 2a + 1b <= 18
Since according to the question;
- Tony has $18 to buy apples and bananas for a fruit salad.
- Apples cost $2 per pound and bananas cost $1 per pound.
- Let the number of apples bought be; a
- Let the number of bananas bought be; b
Therefore, the inequality to describe the situation is;
This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.
Additionally, Two possible combinations of pounds and apples that Tony can buy are;
- Tony buys 9 apples and no banana
- Tony buys 18 bananas and no apple.

Distance formula: sqrt((x2-x1)^2 + (y2-y1)^2)
distance = sqrt((-1 -2)^2 + (-5-5)^2)
distance = sqrt(109)
Distance = 10.44
