You can subtract 8 -1=7 and then add 7+7=14 and then do 14+1=15 because we subtracted 1 from 8.

The measures of two sides of a triangle are 15 and 16. between what two numbers must the measure of the third side fall?
QveST [7]
If it is a right triangle and you given me adjacent and opposite the formula is
{r}^{2}   =  {x}^{2}  +  {y}^{2}
third side = 21.93

if its not right triangle you need the angle to solve

David, a platform diver, dives into the pool during practice. The height of David above the water at any given time, s, can be m
ella [17]

Check the pictures below.

if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.

if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is

h(s) = -4.9(s - 2)(s + 1).

The ___________ of a lens or mirror is a rotational symmetry axis of the surfaces.
densk [106]

Answer:

Optical axis

Step-by-step explanation:

Optical axis is the rotational symmetry axis of the surfaces.

A line with a certain degree of rotational symmetry is called as the optical axis in an optical system.

It is the straight line that passes through the geometric center of the lens and joins two curvature centers of its surfaces.

It is also called as the principal axis.

a) We kindly invite to check the image attached below to see a detailed graph of the <em>piecewise</em> function.

b) The <em>piecewise</em> function is continuous.

<h3>How to understand a piecewise function</h3>

A <em>piecewise</em> function is a <em>conditional</em> combination of two or more functions, whose expression depends on which value of the domain is the function evaluated at.

a) The <em>piecewise</em> function described in the question is plotted on a graphing tool (i.e. <em>Desmos</em>), whose result is presented in the image attached below.

b) A function is <em>continuous</em> if and only if there is one value from range for every value of domain. The <em>piecewise</em> function is continuous as <em>linear</em> functions are continuous and the two functions of the <em>conditional</em> combination have the same value for x = 30.
