Given:

Height of cone = 3 cm

Radius of cone = diameter ÷ 2 = 16 cm ÷ 2 = 8 cm

To be able to get the volume of the cone, we will be using the following formula:

$\text{ Volume = }\frac{\text{ }\pi r^2h}{3}$

We get,

$\text{ Volume = }\frac{\text{ }\pi r^2h}{3}$ $\text{ = }\frac{(3)(8)^2(3)}{3}$ $\text{ = }(3)(64)^{}$ $\text{ Volume = }192cm^3$

Therefore, the volume of the cone is 192 cm

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 $y = 0.07\cdot e^{0.73\cdot x}$ .

The chance that a positive response is obtained from Chicago fro program 1 is %. The chance that a positive response is obtained

igor_vitrenko [27]

Answer:

The chance that positive response obtained for program 1 is 65.90

And The chance that positive response obtained for program 2 is 87.50

Step-by-step explanation:

Given data as :

The positive response for program of different cities in percentage

Now, The positive response is obtained from Chicago for program 1 is 65.90

The total positive response for program 1 in % = 68.80

So, The chance that positive response obtained = 65.90

Again ,

The positive response is obtained from Chicago for program 2 is 87.50

The total positive response for program 1 in % = 81.70

So, The chance that positive response obtained = 87.50

Hence The chance that positive response obtained for program 1 is 65.90

And The chance that positive response obtained for program 2 is 87.50 answer
