Answer:

(x-6)^{2}+(y+16)^{2}=6,400

Step-by-step explanation:

we know that

The equation of a circle in standard form is equal to

(x-h)^{2}+(y-k)^{2}=r^{2}

In this problem we have

The center of the radio tower (position) is the point (6,-16)

The radius of the radio tower (range) is r=80\ miles

substitute

(x-6)^{2}+(y+16)^{2}=80^{2}

(x-6)^{2}+(y+16)^{2}=6,400

The straight line 3y = 5x + h - 6 intersect the x-axis at 4k, where h and k are constants. explain h in terms of k
inn [45]

When a function intersects with the x-axis, it's y value must be 0. That means when the straight line intersects with the axis, it's at the point (4k,0), so plugging those numbers into our original equation yields:

0=20k+h-6 \implies\\ 6=20k+h \implies \\ 6-20k=h

The following table shows the final scores for a group of mini golf reset adventure Land find the median number of strokes
solong [7]
The median would be the middle data point. Let’s list the points

25, 26, 31, 39, 32, 57

Put them in order from least to greatest

25, 26, 31, 32, 39, 57

There is an even amount of data so take the two center points and divide by 2

31 + 32 = 63

Divide by 2

31.5

There would be an average of 31.5 strokes

Three tenths of the sum of -2 and -28 written as numerical expression
Anuta_ua [19.1K]
Three tenths is the same as 3/10

the sum of -2 and -28 is -30

3/10 of -30 is the same as the products of the two

3 x -30 / 10 = -90/10 = -9

Your answer is


3(-2 + -28)/10 = -9
