Answer:

Option B) y = (1.31)(2.8^{x}) is the correct option.

Step-by-step explanation:

<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>

Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.

Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.

Or we can use the cost function,

J = \frac{((y(i))-y)^2}{2m} , to find which function has the least error.

By applying the above results,we find Option B is correct.

What is the diameter of the circle whose center is at (6,0) and passes through the point (2,-3)
Aleksandr [31]

Answer: 10 units

Step-by-step explanation:

Use the distance formula(√(x1-x2)^2+(y2-y1)^2)

\sqrt{(6-2)^2+(0-(-3))^2} \\\\\sqrt{4^2+3^2}\\\\\sqrt{16+9}\\ \\\sqrt{25}\\ \\5

Thus, the radius of the circle is 5.  Because the diameter is 2r, the diameter = 2(5) = 10

Hope it helps <3

Figure not drawn to scale.
DerKrebs [107]
Though you do not provide a diagram, I am going to give this a try by assuming that O is the center of the circle, OA is a radius, and angle AOB is a central angle that measures 88 degrees.

We want to find out the area of sector AOB. First, we need to find the area of the entire circle. The area of a circle is given by A= \pi  r^{2} and since the radius of this circle is equal to 1, the area is \pi ( 1^{2} )= \pi

Next we need to know what fraction of the circle sector AOB represents. The distance around the circle is 360 degrees but the central angle that intercepts arc AB is 88 degrees. That meas that the fraction of the circle the sector represents is given by \frac{88}{360}= \frac{11}{45}

We multiply this by the area to obtain \frac{11}{45} \pi which is the area of the sector.

A restaurant offers 77 possible​ appetizers, 1515 possible main​ courses, and 99 possible desserts. how many different meals are
JulsSmile [24]
First you need to multiply all the numbers to get 11548845 and then for example you need to do this (77*1515)+(77*99)+(99*1515) = 274263 to get and then you need you need to add 77,1515,99 to get 1691 and then you add 11548845, 274263, and 1691 to get 11824799 and that is the total number of possible outcomes of meals that you can get.
<em> hope this helps you and the the reason I explained is so you dont have to ask this type of question again.</em>
