15) In your own words, write three or four sentences explaining what exponents are and how they are used in math
Scorpion4ik [409]

Answer:

Exponents

Step-by-step explanation:

exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.

Exponents can also be defined as 10 raised to a power x whether positive or negative

10 {}^{x}

They are mostly used in expressing units in standard form.

<h3>examples of basic positive exponents</h3>

{10}^{2}  = 100

10 {}^{3}  = 1000

{10}^{4}   = 10000

{10}^{5}  = 100000

basically the power represent the the number of zeroes after the 1.

<h3>examples of basic negative exponents</h3>

{10}^{ - 2}  = 0.01

{10}^{ - 3}  = 0.001

{10}^{ - 4}  = 0.0001

10 ^{ - 5}  = 0.00001

in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.

this is the basic lay down of how exponent work but one more quick example for maximum understanding

<h3>quick example</h3>

4 \times  {10}^{4}  = 0.0004

4 \times  {10}^{4}  = 40000

8.69 \times 10 {}^{ - 3}  = 0.00869

8.69 \times 10 {}^{  3}  = 8690

hope you grasp the concept involved in multiplication with other terms.

cheers

Y=-x^2+20x-64 what is the max height
Inessa [10]

Answer:

36

Step-by-step explanation:

The maximum height is the y-coordinate of the vertex

given a quadratic in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = - x² + 20x - 64 is in standard form

with a = - 1, b = 20 and c = - 64, hence

x_{vertex} = - \frac{20}{-2} = 10

substitute x = 10 into the equation for y

y = - (10)² + 20(10) - 64 = 36 ← max height
