Answer:

well dependes on how u need them

when a negative and negattive are next to eachother

3- (-6) this 3+6 becomes a positive

you also have where 2 negatives make a positive

a positive plus a negative will give you positive. same as times them.

negative minus negative equals negative, negative minus positive equals positive.

hope it helps

What is the surface area of this design?<br> A.76in2<br> B.280in2<br> C.360in2<br> D.392in2

Phantasy [73]

Answer:

There are 8 faces on the figure.

There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.

Then, there is another side that equals 4 x 4 which is 24.

Another side equals 4 x 6 which is 24.

Another one equals 6 x 6 which is 36.

Another side equals 6 x 6 which also equals 36.

Another side equals 10 x 6 which is 60.

The last side is 10 x 6 which equals 60.

Which should add up to 392 in.

Consider the force field and circle defined below.

grin007 [14]

By Green's theorem,

$\displaystyle\int_{x^2+y^2=9}\vec F(x,y)\cdot\mathrm d\vec r=\iint_D\left(\frac{\partial(xy)}{\partial x}-\frac{\partial(x^2)}{\partial y}\right)\,\mathrm dx\,\mathrm dy=\iint_Dy\,\mathrm dx\,\mathrm dy$

where $C$ is the circle $x^2+y^2=9$ and $D$ is the interior of $C$ , or the disk $x^2+y^2\le1$ .

Convert to polar coordinates, taking

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\end{cases}\implies\mathrm dx\,\mathrm dy=r\,\mathrm dr\,\mathrm d\theta$

Then the work done by $\vec F$ on the particle is

$\displaystyle\iint_Dy\,\mathrm dx\,\mathrm dy=\int_0^{2\pi}\int_0^3(r\sin\theta)r\,\mathrm dr\,\mathrm d\theta=\left(\int_0^{2\pi}\sin\theta\,\mathrm d\theta\right)\left(\int_0^3r^2\,\mathrm dr\right)=\boxed0$

In triangle ABC,if measure of angle A is seven more than four times measure of angle B and measure of angle C is eleven more tha

Yuri [45]

Answer: Angle A is 115 degrees

Step-by-step explanation:

In triangle ABC, the measure of angle A is seven more than four times measure of angle B. This means that

Angle A = 4(Angle B) + 7

The measure of angle C is eleven more than measure of angle B. This means that

Angle C = Angle B + 11.

The equations are

A = 4B + 7 - - - - - - - - 1

C = B + 11 - - - - - - - - - - 2

Recall that the sum of the angles in a triangle is 180 degrees. This means that

A + B + C = 180 degrees

Substituting equation 1 and equation 2 into A + B + C = 180, it becomes

4B + 7 + B + B + 11 = 180

6B + 18 = 180

6B = 180 - 18 = 162

B = 162/6 = 27 degrees

Substituting B = 27 into equation 1, it becomes

A = 4×27 + 7 = 108 +7

A = 115 degrees

Substituting B = 27 into equation 2, it becomes

C = 27 + 11

C = 38 degrees

Sum of the angles is 115 + 27 + 38 = 180
