If the number is X then, reading it through . . .

when she multiples it by itself is 'squared', she then adds 10.01 and get 91.01

The equations is: x^2 + 10.01 = 91.01

Solving: x^2 = 91.01 - 10.01

x^2 = 81

x = +9 or -9 as both +9 and -9 squared = 81

e-lub [12.9K]

Answer:

6.065; 7.358 ; 6.694

Step-by-step explanation:

Given that, profit is quoted using the function :

R = 2pe ^ -0.1p

(a)

When price 'p' = $5

R = 2(5)e^(-0.1*5)

R = 10e^(-0.5)

R = 10 * 0.6065306

R = 6.065

B)

When price 'p' = $10

R = 2(10)e^(-0.1*10)

R = 20e^(-1)

R = 20 * 0.3678794

R = 7.358

C.)

When price 'p' = $15

R = 2(15)e^(-0.1*15)

R = 30e^(-1.5)

R = 30 * 0.2231301

R = 6.694

What is the equation<br> example:: y=3/1x-6
hichkok12 [17]

Answer:

y = 4/6x - 4

Step-by-step explanation:

y = mx + b, m = slope and b = y intercept

Rise over run

Rise = +4

Run = +6

This means the slope is 4/6.

The y intercept is at -4.

Now, plug in the numbers for y = mx + b

y = 4/6x - 4
