Step-by-step explanation:
This is a straight forward division problem.
12/(5/8).
The rule for division of fractions is: invert the denominator and multiply.
For this problem: 12/(5/8) = 12 * 8/5 = 96/5.

How can you tell that a graph is a proportional ( what does it look like and what point will it always go through? )
Answer:
You can tell if a graph is a proportional relationship, by seeing if the line passes through the origin (0, 0). It looks like a straight line, which comes or goes through the origin.
Answer:
To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship.
A hailstone falls from a cloud at a height of 1,600 ft. If the equation for height as a function of time is h(t) = -16t2 + initial height where t is time in seconds and h(t) is height in feet, how many seconds will it take for the hailstone to hit the ground? [?] seconds
Answer:
10 seconds
Step-by-step explanation:
The function is
[tex]h(t)=-16t^2+\text{Initial height}[/tex]
Initial height = 1600 ft
t = Time taken
[tex]0=-16t^2+1600[/tex]
[tex]\Rightarrow -16t^2=-1600[/tex]
[tex]\Rightarrow t^2=\dfrac{1600}{16}[/tex]
[tex]\Rightarrow t^2=100\\\Rightarrow t=\pm 10[/tex]
So, time taken by the hailstone to reach the ground is [tex]10\ \text{seconds}[/tex].
Answer:
10 seconds

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = –8x + x2 + 7 ?

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = –8x + x2 + 7 ?
left 4, down 9
left 4, up 23
right 4, down 9<<<<<<< CORRECT
right 4, up 23
The translation should be right 4 units and down 9 units.
Which translation should we use?
First, we need to find the vertices of both functions.
for f(x) = x^2 the vertex is at (0, 0), as we already know.
For g(x) = -8x + x^2 + 7 the x-value of the vertex is at:
x = -(-8)/(2*1) = 4
Evaluating g(x) at x = 4 we get:
g(4) = -8*4 + 4*4 + 7 = -9
So the vertex is at (4, -9).
To go from (0, 0) to (4, -9) we need to move right 4 units and down 9 units, so the correct option is the third one.

classify the triangle by its sides, and then by angles
Answer:
riangles can be classified by their sides and by their angles. ... If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.
Step-by-step explanation:
An experiment consists of tossing a die and then flipping a coin once if the number on the die is even. If the number on the die is odd, the coin is flipped twice. Using the notation 4HH, for example, to denote the outcome that the die comes up 4 and then the coin comes up heads, and 3HTHT to denote the outcome that the die comes up 3 followed by a head and then a tail on the coin, construct a tree diagram to show the 18 elements of the sample space SS.
For the sample space SS
(a) list the elements corresponding to the event AA that a number less than 3 occurs on the die;
(b) list the elements corresponding to the event BB that two tails occur;
(c) list the elements corresponding to the event A′A ′;
(d) list the elements corresponding to the event A′∩BA ′ ∩B;
(e) list the elements corresponding to the event A∪BA∪B.

What's the difference between an opened circle on a number line and a closed circle. ( Pls give an example)
Answer:
Open circle: used for < (less than) or > (greater than) because the number is not part of the solution.
Closed circle: used for ≥ (greater than or equal to) or ≤ (less than or equal to) because the number is part of the solution.
Shading:
Shade to the right for > or ≥
Shade to the left for < or ≤
Step-by-step explanation:
2 < x < 5
Place a open circle on 2 with shading to the left and a open circle on 5 with shading to the right.
4 ≤ x ≤ 10
Place a closed circle on 4 with shading to the left and a closed circle on 10 with shading to the right.
