Answer:
33 Students
Step-by-step explanation:
4:7 => 4+7 = 11 < 24 not enough
8:14 => 8+14 = 22 < 24 not enough
16:28 => 16+28 = 44 > 40 alot more
12:21 => 12+21 = 33
24 < 33 < 40
Vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when . Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of in the given equation . Here, co-efficient of
So, vertex<em> </em>is at
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Answer:
48 years
Step-by-step explanation:
Let the ratio of their ages be
4:2:1
Sum up the numbers
4+2+1
= 7
Their total ages is 84
7/84
= 1/12
Therefore Jim age can be calculated as follows
= 12×4
= 48
Hence Jim is 48 years
