A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway

MrRissso [65]

Answer:

16 miles

Step-by-step explanation:

Given that :

1 unit = 3 miles

High School = (2, 4)

Stadium = (7, 6)

Approximate distance between high school and stadium :

Distance between High school and Stadium

x1 = 2 ; y1= 4 ; x2 = 7 ; y2 = 6

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Distance = sqrt((7 - 2)^2 + (6 - 4)^2)

Distance = sqrt((5^2 + 2^2))

Distance = sqrt(25 + 4)

Distance =5.3851648 units

1 unit = 3 miles

Approximate Distance in miles :

3 * 5.3851648 = 16.155494

Approximate distance = 16 miles

Find the indefinite integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) dx x(l

Pepsi [2]

I'm assuming the integral is

$\displaystyle \int \frac{dx}{x (\ln(x^2))^5}$

We have

$\ln(x^2) = 2 \ln|x| \implies (\ln(x^2))^5 = 32 (\ln|x|)^5$

Then substituting $y=\ln|x|$ and $dy=\frac{dx}x$ , the integral transforms and reduces to

$\displaystyle \int \frac{dx}{x(\ln(x^2))^5} = \frac1{32} \int \frac{dy}{y^5} \\\\ ~~~~~~~~ = \frac1{32} \left(-\frac1{4y^4}\right) + C \\\\ ~~~~~~~~ = -\frac1{128(\ln|x|)^4} + C$

which we can rewrite as

$128 (\ln|x|)^4 = 8\cdot2^4(\ln|x|)^4 = 8 (2\ln|x|)^4 = 8 (\ln(x^2))^4$

and so

$\displaystyle \int \frac{dx}{x (\ln(x^2))^5} = \boxed{-\frac1{8(\ln(x^2))^4} + C}$

Trigonometry question

Olegator [25]

Answer:

acute

Step-by-step explanation:

1. It cannot be right angle as the sides does not satisfy pythagoras theorem.

2. It cannot be obtuse angle as it does not satisfy the rule:

- the length of one side of a triangle must be greater than the differnce and less than the sum of the lengths of the other two sides.
