Mathematics

The <em><u>correct answer</u></em> is:

F(x) is read as “F of x” ; F is the graph at a particular value of x; and y is equal to F(x).

Explanation:

f(x) is read as "f of x" by definition.

F is the function, and f(x) is the function at a given value of x; for instance, f(3) would be where the function is at the value x=3.

f(x) is another way of writing an equation, except it is in function form. This means it is the same as y=.

True:
1) F(x) is read as "F of x".
3) F is the graph at a particular value of x.
5) y is equal to F(x).


1) F(x) is read as "F of x", then first is true.
2) F(x) is the vertical distance on the graph, then second is false.
3) F is the grap at a particular value of x, then third is true.
4) F(x) can be any real number, then fourth is false.
5) y is equal to F(x), then fifth is true.

The equation y 16t 2 18t 405 describes the height in feet of a ball thrown downward at 18 feet per second from a height of 405 f
kumpel [21]

Answer:

Ball hits the ground after 4.5 sec

Step-by-step explanation:

Let a -1, so that the leading coefficient is positive

So our quadratic is

-1 \times (16t^2 +18t -405)

The key coefficients of two binomial variables can be 1 and 16, or 2 and 8, or 4 and 4, for the leading coefficient of 16.

Yet they can't actually be 4 and 4 because the linear (x) term coefficient has to be a multiple of 4, which it isn't and leading coefficients 1 and 16 on the binomial factors is not likely.

So, 2 and 8 taken as the leading coefficients of  two binomial factors.

For constant  405, possible factorizations are (81\times 5, 27 \times 15, 9 \times 45).

(16t^2 +18t -405) = (8t + 45) (2t - 9)

Taking first factor, thus we find  negative value for given time t. But  second time equivalent to zero gives the value of 4.5 for t

Thus ball hits the ground after 4.5 sec

How do you find the surface area of a regular triangular prism
Dmitry [639]
So a triangular prisim is like a triangle stacked on top of x number of identical triangles making a height, like a piece of paper made into a stack

so
basically find the area of each side and add

look at diagram/attachment
find area of triangle
1/2 b times h= area of 1 triangular face

multiply by 2 because 2 sides so 1/2 times 2 b times h=b times h

then 3 other sides
find area of each side and add
areas=(H times B)+(H times c)+(H times a)

so SA=(b times H)+(H times B)+(H times c)+(H times a)
