Answer:

b. 38 cm.

Step-by-step explanation:

Note that the 2 sides  which are unmarked are the opposite sides of 2 rectangles so they are both  = 2 cm.

Now we  just add all the given sides.

Starting with 6 on the top and travelling clockwise:

Perimeter = 6 + 2 + 2 + 3 + 3 + 2 + 7 + 2 + 3 + 3 + 3 + 2

=  38 cm.

Perimeter is basically adding all of the sides so you have to add; 6 + 2 + 3 + 2 + 3 + 3 +3 + 3 + 7 + 2 + 2 + 2= 38 .

38 is the perimeter.

Sin(x2 + y2) da r , where r is the region in the first quadrant between the circles with center the origin and radii 2 and 5
sweet [91]
Converting to polar coordinates gives

\displaystyle\iint_R\sin(x^2+y^2)\,\mathrm dA=\int_{\theta=0}^{\theta=\pi/2}\int_{r=2}^{r=5}\sin(r^2)r\,\mathrm dr\,\mathrm d\theta
=\displaystyle\pi\int_{r=2}^{r=5}2r\sin(r^2)\,\mathrm dr
=\displaystyle\pi\int_{r^2=4}^{r^2=25}\sin(r^2)\,\mathrm d(r^2)
=-\cos(r^2)\bigg|_{r^2=4}^{r^2=25}
=\pi(\cos4-\cos25)

The angle measures of a triangle are in the ratio 5:6:7. find the angle measures of the triangle
Mandarinka [93]

Answer:

50°, 60°, 70°

Step-by-step explanation:

Sum the parts of the ratio, 5 + 6 + 7 = 18 parts

The 3 angles in a triangle sum to 180° , then

180° ÷ 18 = 10° ← value of 1 part of the ratio, then

5 parts = 5 × 10° = 50°

6 parts = 6 × 10° = 60°

7 parts = 7 × 10° = 70°

The angle measures of the triangle are 50° , 60° , 70°

What is the derivative of y with respect to x if y = 2/X4
zepelin [54]
You're correct, the answer is C.

Given any function of the form y=x^n, then the derivative of y with respect to x (\frac{dy}{dx}) is written as:
\frac{dy}{dx}=nx^n^-^1

In which n is any constant, this is called the power rule for differentiation.

For this example we have y= \frac{2}{x^4}, first lets get rid of the quotient and write the expression in the form y=x^n:
y= \frac{2}{x^4} =2x^-^4

Now we can directly apply the rule stated at the beginning (in which n=-4):
\frac{dy}{dx}=(2)(-4)x^{-4-1}=-8 x^{-5}= -\frac{8}{x^5}

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).
