They are the same, therefore they would be proportional

If two triangles are similar (in the geometric sense), then the sides must be proportional.

If f(x)=-5^x-4 and g(x)=-3x-2 find (f-g)(x)

sukhopar [10]

Answer:

$(f-g)(x) = 5^x +3x -2$

Step-by-step explanation:

The value (f-g)(x) means subtract the function g from f. This can be done by combining only like terms between each.

$(f-g)(x) = 5^x - 4 -(-3x-2)\\(f-g)(x) = 5^x - 4 +3x + 2\\(f-g)(x) = 5^x +3x -2$

Russell randomly surveys seventh-graders in his school and finds that 6 of 30 attend summer camp. If there are 200 seventh-grade

Lady_Fox [76]

Answer:

Step-by-step explanation:

6 of 30 is the ratio 6 to 30 or 6/30.

6/30 reduces to 1/5

The survey shows that 1/5 of the students attend summer camp.

1/5 of 200 = 1/5 * 200 = 40

The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth) A) 34.06 B) 37.12 C) 40.24 D

Nata [24]

Answer: OPTION B.

Step-by-step explanation:

The missing figure is attached.

For this exercise you need to use the Pythagorean Theorem. This is:

$a^2=b^2+c^2$

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.

Then you can say that:

$a=PR\\b=PS=17\\c=RS=33$

Therefore, knowing these values, you can substitute them into $a^2=b^2+c^2$ :

$PR^2=17^2+33^2$

Finally you must solve for PR in order to find its value. This is:

$PR=\sqrt{17^2+33^2}\\\\PR=37.12$
