Answer:

2,2.5

Answer: Between <u>2</u> and <u>2.5</u> seconds

How am I getting those values? Those values are selected from the 't' column on the left side of the table. These are time values in seconds. Note how t = 2 corresponds to h = 0.4; while t = 2.5 corresponds to h = -10.6

The change in sign for the height, from positive to negative, means that the height h must be zero at some point between t = 2 seconds and t = 2.5 seconds. We don't know where exactly, but we know that h = 0 at least once in this interval. This is because the height is a continuous function. There are no jumps or gaps in the height (the object can't teleport or anything)

Which equation has a graph that is a parabola with a vertex at (–2, 0)?
RideAnS [48]

Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:

y = (x + 2)²

<h3>What is the equation of a parabola given it’s vertex?</h3>

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:

y = (x + 2)²

The area of the base of the cone is 64π square millimeters, and the area of the lateral surface is 112π square millimeters. Find
baherus [9]

Answer:

Radius = 8 mm

Slant Height = 14 mm

Step-by-step explanation:

Base of a cone is a circle.

Area of circle is given as A=\pi r^{2}

Where r is the radius.

Given that

A = 64 \pi\ mm^2\\\Rightarrow  \pi r^{2} = 64\pi \\\Rightarrow r^{2}  = 64\\\Rightarrow r = 8\ mm

Hence, radius is 8 mm.

Formula for Lateral Surface Area of a cone:

LSA = \pi rl

Where r is the radius and

l is the slant height of cone

Given that LSA = 112 \pi\ mm^2

\Rightarrow 112\pi = \pi \times 8 \times l\\\Rightarrow 8 \times l = 112\\\Rightarrow l = 14\ mm

Hence, slant height is 14 mm
