Which of the following expressions are equivalent to -5/-7×-11/-6 ​
USPshnik [31]

Answer:

B.

Step-by-step explanation:

-5/-7×-11/-6

= (-5 * -11)  / (-7*-6)

= 55 / 42.

A. =  - (6/-11) = 6/11

-5/7 * 6/11 =  -30/77.

B.   - (-11/7) = 11/7

5/6 * 11/7

= 55/42.

Write an exponential model given the points ( 7, 12 ) and ( 8, 25 ). Round to the nearest hundredth.
inna [77]

Answer:

The exponential model is y = 0.07\cdot e^{0.73\cdot x}.

Step-by-step explanation:

The exponential model can be modelled by the following mathematical expression:

y = A\cdot e^{B\cdot x} (1)

Where:

x - Independent variable.

y - Dependent variable.

A, B - Coefficients.

If we know that (x_{1}, y_{1}) = (7,12) and (x_{2}, y_{2}) = (8,25), then we get the following system of equations:

A\cdot e^{7\cdot B} = 12 (2)

A\cdot e^{8\cdot B} = 25 (3)

If we divide (3) by (2), we calculate the value of B:

e^{B}=\frac{25}{12}

B = \ln \frac{25}{12}

B \approx 0.734

And by (2), we determine the value of A:

A = 12\cdot e^{-7\cdot B}

A = 0.0704

The exponential model is y = 0.07\cdot e^{0.73\cdot x}.

I got the answer but I don't understand what the -1 does
Kazeer [188]
The -1 affects the coefficient of the entire term.

Without the -1,
the term has a positive coefficient.
(3a)² = 9a²

However, with the -1,
the term has a negative coefficient.
-(3a)² = -9a²
