The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds
Answer:
4 seconds
Step-by-step explanation:
fish broke the water's surface in 1 second and went back into the water at 5 seconds
∴ it was out of the water for 4 seconds

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters

In a regular tessellation 3,4,6 sides can be tessellating regular
polygon.
What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Whats the slope of the line?
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.
Which factored polynomial is shown in the graph?
A) y = (x + 2)(x + 1)(x + 4)
B) y = (x + 2)(x − 1)(x + 4)
C) y = (x + 2)(x − 1)(x − 4)
D) y = (x − 2)(x − 1)(x + 4)
Answer:
B
Step-by-step explanation:
First, we can determine the zeros of the function.
We can see that the graph passes through the x-axis at the points: x = -4, -2, and 1.
Therefore, we have three factors:
[tex](x-(-4)),\, (x-(-2))\text{ and } (x-(1))[/tex]
Thus, our function will be:
[tex]y=(x+4)(x+2)(x-1)[/tex]
Our answer is B.

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)
m<L = (7x + 9)° is an inscribed angle
m(KM) = 46° is its intercepted arc
Therefore:
7x + 9 = ½(46)
Multiply both sides by 2
2(7x + 9) = 46
14x + 18 = 46
14x + 18 - 18 = 46 - 18
14x = 28
14x/14 = 28/14
x = 2
