The table represents the height of a ball thrown up from the roof of a building, h(t), in meters, t seconds after it is thrown u

pward.
A 2-column table with 7 rows. The first column is labeled t with entries 0, 2, 4, 6, 8, 10, 12. The second column is labeled h(t) with entries 0, 60.4, 81.6, 63.6, 6.4, negative 90, negative 225.6.

Which statements are true? Check all that apply.

The ball is at the same height as the building between 8 and 10 seconds after it is thrown.
The height of the ball decreases and then increases.
The ball reaches its maximum height about 4 seconds after it is thrown
The ball hits the ground between 8 and 10 seconds after it is thrown.
The height of the building is 81.6 meters.

Area as a sum:<br> Area as a Product:<br><br><br> I need the are as a sum Nd a product
PSYCHO15rus [73]

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are 2x^2,10x, 3x, 15.

The area as a sum is the sum of all the terms of given area model.

Area as a sum = 2x^2+10x+3x+15

                        = 2x^2+13x+15

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = 2x^2+10x+3x+15

                        = 2x(x+5)+3(x+5)

                        = (x+5)(2x+3)

Therefore, the area as a sum is 2x^2+13x+15 and the area as a product is (x+5)(2x+3).

An isosceles triangle has an angle that measures 98°. Which other angles could be in that isosceles triangle? Choose all that ap
Tamiku [17]

an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.

if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.

so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.


Check the picture below.

A box is contructed out of two different types of metal. the metal for the top and bottom, which are both square, costs $5 per s
patriot [66]
Total cost, C = 8x^2 + 12xz 
volume, V = (x^2)*z = 10 
C = 8x^2 + 12x*10/x^2 
= 8x^2 + 120/x 
dC/dx = 16x - 120/x^2 = 0 
16x = 120/x^2 
x^3 = 120/16
 x = 1.957 ft

d^2C/dx^2 = 16 +240/x^3 = +ve for x = 1.957 
so, C is minimum when
x = 1.957 ft z = 2.61 ft

Length of the base x is 1.957 ft and height of side z is 2.61 ft
