Answer:

8.49 units

Step-by-step explanation:

CD is the length opposite angel E

Use cosine law

CD² = 10² + 5² - 2(10)(5)cos(58)

CD² = 72.00807358

CD = 8.485757101

CD = 8.49 units

Answer:

<h2>After two seconds, the ball reached 9 units up.</h2>

Step-by-step explanation:

The given function is

y=-x^{2} +4x+5

The given function models the path of the ball.

The maxium height the ball reached is given by the vertex of this function, which has coordinates V(h,k), where h=-\frac{b}{2a} and k=f(h).

From the equation, we know that a=-1, b=4 and c=5. Replacing these values, we have

h=-\frac{4}{2(-1)}=2

k=f(2)=-(2)^{2} +4(2)+5=-4+8+5=9

Where k determines the height and h the time when the maximum height was reached by the ball.

The maximum height is 9 units.

Therefore, after two seconds, the ball reached 9 units up.

To answer question 12, you first need to know the definition of a <em>prism</em> and a<em> pyramid.

</em>A <em>pyramid </em> is a 3-D structure with one base, whose outer faces are made of triangles, and meet at a single point at the top.

A <em>prism</em> is any 3-D shape with a base of any number of sides, another base with the same amount of sides, and faces joining the two together on every side of the bases.

12.
Shape A is a <em>pyramid</em>, because it has one base, and all the faces join together in at one point.

Shape B is a <em>prism</em>, because it has two bases, and faces joining every side of the bases.

Shape C is a <em>prism.</em>

Shape D is a <em>pyramid.

</em>For #13, you have to know the definition of a cube to figure out the math of how many cubes there are.

A cube is a 3-D shape with six sides, all made up of squares of the same size.

The box has a volume of 120 cubic inches, and each cube is 1 inch. Since every side of a cube is equal, a 1-inch cube is one cubic inch.

This means that a box with a volume of 120 cubic inches will fit 120 of the 1 inch cubes.

1 layer of the cubes, in the diagram, is 8 cubes by 3 cubes, or 24 cubes total.

To find the number of layers needed to fill the box, you divide 120 by 24.

120 ÷ 24 = 5

The answer to #13 is 5 layers.
