Answer: 14.1
Step-by-step explanation:
Law of cosines:
d^2 = 8^2 + 10^2 - 2(8)(10)cos103
You can use the associative property because the order does not matter with 2 or more numbers if you are just finding the sum.
26 + 19 + 34 + 21 = 100 students total
Given:
Violinists : Cellists = 7:3.
Number of violinists in the school orchestra = 21
To find:
The combined number of cellists and violinists.
Solution:
Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.
Then, combined number of cellists and violinists is
...(i)
Number of violinists in the school orchestra = 21
Divide both sides by 7.
Now, the combined number of cellists and violinists is
[Using (i)]
Therefore, the combined number of cellists and violinists is 30.
Answer:
8/21
Step-by-step explanation:
(-2/3)/(-7/4)
When dividing, reciprocate the dividend then multiply to the divisor.

First problem: f(x) = -(x+4)^2 + 1
a) First, graph g(x) = x^2 (a parabola). Then reflect your graph in the x-axis, because of the "-" sign. This will give you the graph of h(x) = -x^2.
b) Now move the entire graph 4 units to the LEFT. This will give you the graph of j(x) = -(x+4)^2.
c) Now move the entire graph of j(x) UP by one unit.
This will give you the desired graph, of f(x).
