50 points and BRAINLIEST!

Mathematics
1 answer:
Harman [31]3 years ago
4 0

Answer:

Step-by-step explanation:

The general equation of a circle is , x² + y² + 2gx + 2fy + c = 0

Substituting the three points we get the following equations,

2g +14f +c=-50

14g - 2f + c =-50

16g +12f + c = -100

Solving these equations we get,

g =-4, f = -3, c = 0

Hence general equation of circle is,

x² + y² - 8x - 6y  = 0

The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.

Step-by-step explanation:

Step 1:

To determine if the function represents growth or decay, we substitute values to x.

If the values increase with an increase of x, it represents growth.

If the values decrease with an increase of x, it represents decay.

Step 2:

If x= 10, y = 1,300 (\frac{1}{2})^{\frac{10}{69} }  =  1,300 (0.9044) = 1,175.72.

If x=11,y = 1,300 (\frac{1}{2})^{\frac{11}{69} }  =  1,300 (0.8953) = 1,163.89.

So as x increases the value of y decreases, so it represents decay.

Step 3:

The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.

The percentage rate of change = \frac{y(x=11) - y(x=10)}{y(x=10)}.

Substituting the values, we get

The percentage rate of change =\frac{1,175.72-1,163.89}{1,175.72}(100) = 1.00619\%.

As the values of y decrease with an increase in x, it is the percent decrease per unit.

What is the result when the number 20 is decreased by 75%?\
Viefleur [7K]

Answer:

5

Step-by-step explanation:

If 20 is <em>decreased </em>by 75%, you would have to do 20×0.25 because 1.00-0.75= 0.25. Therefore, the answer to your question would be 5.

Hope this was helpful!!!

Point A has coordinates (-5, 3). If point (1,6) is
gtnhenbr [62]

Answer:

(3, 7)

Step-by-step explanation:

 (4/3)P -(4/3)A + A = B . . . . . . add A

 (4P -A)/3 = B . . . . . . . . . . . . . simplify

Then the coordinates of point B are ...

 B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3

 B = (3, 7)
