Answer:

Step-by-step explanation:

A function

$a \times {b}^{x}$

where a is the initial value and b is the multiplicative rate of change.

In the function,

$f(x) = 2 \times {5}^{x}$

5 is the value of b so

5 is the multipicative rate of change

The area of a rectangular parking lot is 7081 m²

Lubov Fominskaja [6]

Step-by-step explanation:

So the question is easy ....The thing that you need to do here is ...You should divide area by length....and you will get your answer....

Area of square = l²
Area of rectangle = l × b

Area of rectangular parking lot = 7081 m²

length of parking lot = 97 m

Width = ?

Now,

Area = l × b

7081 = 97 × b

7081 / 97 = b

b = 73 m

Hence the width is 73 m....

5x²+4x+3=0 solve for x

juin [17]

Answer:

${ \underline{ \sf{x \: is \: \: \{ \frac{ - 5 + i \sqrt{35} }{10} \} } \: \: and \: \: \{ \frac{ - 5 - i \sqrt{35} }{10} \}} }$

Step-by-step explanation:

$5 {x}^{2} + 4x + 3 = 0$

from quadratic formular:

${ \sf{x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }}$

general equation:

${ax}^{2} + bx + c = 0$

a is 5, b is 4 and c is 3:

substitute in formular:

${ \sf{x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 5 \times 3) } }{(2 \times 5)} }} \\ \\ { \sf{x = \frac{ - 5± \sqrt{ - 35} }{10} }}$

but from complexes, i² = -1

${ \sf{x = \frac{ - 5± \sqrt{35 {i}^{2} } }{10} }} \\ \\ = { \sf{x = \frac{ - 5±i \sqrt{35} }{10} }}$
