On a scaled map,a rectangular poster has dimensions of 6 inches by 8 inches.If one inch on the scale equates to 10 meters in rea
Sever21 [200]
If one inch equals 10 meters, then multiply each inch by 10 to get the real dimensions (in meters)
6 * 10 = 60
8 * 10 = 80
Then multiply the length of the sides to get the area
60 * 80 = 4800 meters squared.

A football is kicked toward the goal. the height of the ball is modeled by the function h(t) = −16t2 64t, where t equals the tim
diamong [38]

The function H(t) = -16t^2 + 64t exists in a parabola.

The axis of symmetry of a parabola exists at the midpoint between the two real roots.

The roots exist the solutions of H(t) = 0

To estimate the roots equation exists -16t^2 + 64t = 0

Factor t(-16t + 64) = 0

t = 0 and -16t + 64 =0

-16t + 64 = 0

t = 64 / 16 = 4

t = 4

Then the two roots are t = 0 and t = 4, and the axis of symmetry exists

t = (0+4)/2 = 4/2 = 2

<h3>How to estimate the axis of symmetry?</h3>

The axis of symmetry exists at t = 2.

It represents the time at which the ball is at the higher point, the maximum height.

You can find the maximum height replacing t = 2 in the function H(t)

H(t) = -16(2^2) + 64(2)

= 64 feet.

And you can also deduce that the second part of the flight will take 2 seconds, for a total flight time of 4 seconds.

Answer:

width = 5k^2

length( 3k^2 +7k +4)

Step-by-step explanation:

15k^4 +35k^3 +20k^2

The width is the greatest common factor

We can factor 5k^2 out

5k^2( 3k^2 +7k +4)

The length is what is inside the parentheses

Sveta_85 [38]

Answer:

16 students can sit around a cluster of 7 square table.

Step-by-step explanation:

Consider the provided information.

We need to find how many students can sit around a cluster of 7 square table.

The tables in a classroom have square tops.

Four students can comfortably sit at each table with ample working space.

If we put the tables together in cluster it will look as shown in figure.

From the pattern we can observe that:

Number of square table in each cluster   Total number of students

                     1                                                                 4

                     2                                                                6

                     3                                                                8

                     4                                                                10

                     5                                                                12

                     6                                                                14

                     7                                                                16

Hence, 16 students can sit around a cluster of 7 square table.

Vance used the associative property to write (4.5m+7/8)-9 as the equivalent expression 4.5(7/8-9). Did Vance apply the associati
baherus [9]
Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression

Justification:

1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.

2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.
