Answer:
Since radical 45 is equal to radical 9 times radical 5, and because radical 9 is equal to 3 (since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5
Answer:
yes
Step-by-step explanation:
80 ÷ 20 = 4
56 ÷ 14 = 4
yes they are equivalent
Answer:
3/8
Step-by-step explanation:
first year's work is 1/6
second year's work is 1/8
third year's work is 1/12
combining all 3 gives us
1/6 + 1/8 + 1/12
which simplifies to 3/8
Answer:

Step-by-step explanation:
we know that
The function of the graph is a vertical parabola open upward
The vertex is a minimum
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem
Looking at the graph
The vertex is the point (0,-4)
substitute


To determine the value of "a" take a point in the graph
I take the point (3,5)
substitute the value of x and the value of y and solve for a

therefore
The equation of the quadratic function is

Answer:
118 degrees
Step-by-step explanation:
All angles of any triangle have to add up to 180, so 25+37 equals 62. The next angle has to be 118 degrees, because 180-62 equals 118
