Answer:

Yes number 5 is, they are proportional because y is coresponding to x by multiplying by 1/5

No number 6 isn't, you can't go from 3 to 1 and 7 to 3

Angles of a polygon <br>thanks ♡♡♡♡​
FinnZ [79.3K]

Answer:

900 degrees

Step-by-step explanation:

The sum of the interior angles of a polygon can be found by

(n-2)*180 where n is the number of sides

This figure has 7 sides

(7-2)*180

5*180

Suppose a parabola has vertex (6,5) and also passes through the point (7,7). Write the equation of the parabola in vertex form.
jek_recluse [69]

Answer:

Choice B: y = 2\, (x - 6)^{2} + 5.

Step-by-step explanation:

For a parabola with vertex (h,\, k), the vertex form equation of that parabola in would be:

\text{$y = a\, (x - h)^{2} + k$ for some constant $a$}.

In this question, the vertex is (6,\, 5), such that h = 6 and k = 5. There would exist a constant a such that the equation of this parabola would be:

y = a\, (x - 6)^{2} + 5.

The next step is to find the value of the constant a.

Given that this parabola includes the point (7,\, 7), x = 7 and y = 7 would need to satisfy the equation of this parabola, y = a\, (x - 6)^{2} + 5.

Substitute these two values into the equation for this parabola:

7 = (7 - 6)^{2}\, a + 5.

Solve this equation for a:

7 = a + 5.

a = 2.

Hence, the equation of this parabola would be:

y = 2\, (x - 6)^{2} + 5.

Logx - logx-1^2=2log(x-1)
myrzilka [38]

Answer:

x is approximately 2.220744

Step-by-step explanation:

This can be simplified a little using properties of logarithms, and then solve it by graphing:

log(x)-log(x-1)^2=2\,log(x-1)\\log(x)-2\,log(x-1)=2\,log(x-1)\\log(x)=4\,log(x-1)

So we use a graphing tool to find the intersection point of the graph of log(x), and the graph of 4\,log(x-1)

Please see attached image for the graph and solution.

The value of x is approximately 2.220744

Please help with #9 and 10?
son4ous [18]
The value of m is 35 degrees, because the right angle is 90 degrees, therefore, 90-55=35.
The value of t is 55 degrees because is perpendicular to the other 55 degree angle.
