C^2=a^2+b^2-2abcosC
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°

Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
Answer:
g(x) = x^2 + 4x + 4
Step-by-step explanation:
In translation of functions, adding a constant to the domain values (x) of a function will move the graph to the left, while subtracting from the input of the function will move the graph to the right.
Given the function;
f(x) = x2 - 6x + 9
a shift 5 units to the left implies that we shall be adding the constant 5 to the x values of the function;
g(x) = f(x+5)
g(x) = (x+5)^2 - 6(x+5) + 9
g(x) = x^2 + 10x + 25 - 6x -30 + 9
g(x) = x^2 + 4x + 4
