Answer:
8
Step-by-step explanation:
3v-9=7+2v-v
3v-9=7+v
3v-v-9=7
2v-9=7
2v=7+9
2v=16
v=16/2
v=8
Hello!
To find the volume of a cone, use the formula: V = 1/3πr²h.
In the photo, the height is 6 units, and the diameter is 8 units. Since the radius is half the diameter, then the radius is 4 units.
V = 1/3π(4)²(6)
V = 1/3(6)(16)π
V = 2(16)π
V = 32π
V = 100.5309... This can be rounded to about 100.5.
Therefore, the volume of this cone, is about 100.5 units³.
The graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is the graph attached.
<h3>What is one-sided limit for function?</h3>
It should be noted that the limit from one side is simply when the side of the functions is used with respect to the point of interest.
For this graph, the point x = 2 on the left from the point x = 2 lies a ray. The prediction here is that the value of function on x = 2 us the value that the line gives for y.
Therefore, the graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is attached.

<span>We are going to define two equations where b means bagels and m will be muffins,
First equation: 10*b + 4*m = 13
Second equation: 5*b + 8*m = 14
From the second equation, we can isolate b:
b = (14 - 8*m)/5
In the second equation
10*(14 - 8*m)/5 + 4*m = 13
2*(14 - 8*m) + 4*m = 13
28 - 16*m + 4*m = 13
28 -13 = 16*m - 4*m
15 = 12*m
m = 15/12 = 1.25
Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8
So one bagel costs $0.8 and one muffin $1.25</span>
