Answer: maximum height of the football = 176 feet

Step-by-step explanation:

We want to determine the maximum height of the football from the ground. From the function given,

h(t) = -16t^2+96t +32, it is a quadratic function. Plotting graph if h will result to a parabolic shape. The maximum height of the football = the vertex of the parabola. This vertex is located at time, t

t = -b/2a

b = 96 and a= -16

t = -b/2a = -96/2×-16= 3

Substituting t = 3 into the function if h

h(t) = -16×3^2+96×3 +32

=-16×9 + 96×3 +32

= -144+ 288+32

=176 feet

In the figure below, L N equals 4 x minus 7 and M O equals 2 x plus 13. For which value of x is the figure a rectangle?
Georgia [21]

For this case we have the following data:


LN = 4x-7

MO = 2x + 13

So that the figure can be a rectangle, its diagonals must be equal, that is, LN = MO

In this way we have:


4x-7 = 2x + 13

Clearing x we have:

4x-2x = 13 + 7 \\2x = 20

x=\frac{20}{2} \\x = 10

Thus, x must be equal to 10 so that the figure is a rectangle.


Answer:


x = 10

Option A

Write this ratio 1:3.5 in the form p:q where p and q are whole numbers
Orlov [11]

We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.

Consider the ratio of 1 and 3.5,

1 : 3.5 = \frac{1}{3.5}

= \frac{10}{35}

Reducing the above fraction to its lowest form.

So, we get \frac{10}{35}=\frac{2}{7}

Therefore, the ratio 1 : 3.5 is expressed as \frac{2}{7}

where 2 and 7 are the whole numbers.

Hey some help please and thank.
tatyana61 [14]
Think of how many there are. im not sure if you put these into ratios or not...

like for number 3 think of how many numbers 1-9 are multiples of three

1  2  3  4  5  6  7  8  9

and once you get that number you make it out of 9 because there were 9 numbers

Example

3:9  3/9 

for questions one and two its out of 52 and if you don't know how many clubs and hearts are in a deck you can look it up and put it in a ratio with 52
