xxMikexx [17]

Answer:

Dimensions of rectangle : Width = 2x , Length = 49 - x^2

Area of Rectangle = 98x - 2x^3

Step-by-step explanation:

A rectangle constructed with its base on the​ x-axis and two of its vertices on the parabola

Supposing coordinates of upper right vertex of rectangle are P = (x,y)

Due to parabola symmetry, width of rectangle is twice the horizontal (X) axis distance between Y axis & point P.

Width of rectangle :  2x

Length of rectangle :  y = 49 - x^2

Area of Rectangle = Length x Width

(2x) (49 - x^2)

= 98x - 2x^3

Jabes travelled 3406km in 8days. if he travelled the same distance every day, how many kilometers did he travel per day?
lisabon 2012 [21]

Jabes travels 425.75km per day.

Unit rate is the amount of a certain item related to a single unit of another item.

In the question, we are given that Jabes traveled 3406km in 8 days

We have to find the distances that Jabes travel per day which will be the unit rate of distance per day.

The total distance that jabes traveled in 8 days = 3406 km

Thus, the distance per day jabes traveled can be calculated as:

8 days ⇒3406 km

or, 1 day⇒ 3406/8days = 425.75km

Thus,jabes traveled 425.75 km per day, using the unit rate.

Colt1911 [192]

Answer:

6000 square millimeters

Step-by-step explanation:

Side length of the slanting side can be calculated using the Pythagorean theorem,

L = sqrt(30^2+40^2) = 50

sufrace area of a triangular prism

= surface area of the end sections + the surface area of the three side faces

= 2*(30*40/2) + 40*(30+40+50)

= 1200 + 4800

= 6000 mm^2
