Answer:

Step-by-step explanation:

The standard form of this exponential function is

y=a(b)^x where a is the initial value and b is the growth rate. Our initial value is 490 and our growth rate is .2 so the equation is

y=490(.2)^x

Use suitable Identities and find <br>●( X - 5 ) ( x-5 )<br>●( 3x +2 ) (3x -2 )<br>●( 1+x )(1+x) ​
Nonamiya [84]

Answer:

.

Step-by-step explanation:

<h2><u>IdEnTiTy UsED</u></h2>

{x}^{2}  -  {y}^{2}  = (x + y)(x - y)

1)

(x  -  5)(x - 5)

=(x-5)²

2)

(3x - 2)(3x + 2)

{(3 x)}^{2}  -  {(2)}^{2}

= 9 {x}^{2}  - 4

3)

(1+x)(1+x)

= (1+x)²

Answer:

Distance LM = 5.20 unit (Approx.)

Step-by-step explanation:

Given coordinates;

L(1, 4, 7) and M(2, 9, 8)

Find:

Distance LM

Computation:

Distance between three-dimensional plane = √(x2 - x1)² + (y2 - y1)² + (z2 - z1)²

Distance LM = √(2 - 1)² + (9 - 4)² + (8 - 7)²

Distance LM = √(1)² + (5)² + (1)²

Distance LM = √1 + 25 + 1

Distance LM = √27

Distance LM = 3√3 unit

Distance LM = 3(1.732)

Distance LM = 5.196

Distance LM = 5.20 unit (Approx.)
