HELP ASAP FAST HURRY PLS
erik [133]

Answer:

120 m^2

Step-by-step explanation:

6*2=12 for each narrow piece of the rectangular prism and since there are four multiply 12 times 4. Use the equation 6*6=36 for each of the larger sides and multiply 36 by 2 because there are only two large sides.

Answer:

Step-by-step explanation:

Consider that F(x,y,z) = (x + y, y + z, z + z)

r(t)=(cos t,4sint,\sqt{5}cost)\\r'(t)=(-sint,4cost,-\sqrt{5}sint)\\F(r(t))=[tex]\int\limits^{2\pi}_0 {F(r(t))r'(t)} \, dt \\\\=\int\limits^{2\pi}_0(cost+4sint,4sint+\sqrt{5}cost+cost)(-sint,4cost,-\sqt{5}sint)dt\\\\=\int\limits^{2\pi}_0(-sintcost-4sin^2t+16costsint+4\sqrt{5}cos^2t-5sintcost-\sqrt{5}sintcost)dt\\\\=\int\limits^{2\pi}_0(10sintcost-4sin^2t+4\sqrt{5}cos^2t-\sqrt{5}sintcost)dt\\\\=\int\limits^{2\pi}_0((10-\sqrt{5})sintcost-(4+4+\sqrt{5})sin^2t+4\sqrt{5})dt\\\\(10-\qrt{5})(0)-(4+4+\sqrt{5}(\pi)+4\sqrt{5}(2\pi)\\\\(\sqrt{5}-1)4\pi)[/tex]

What is 3x3-45 divided by (4+1)
Lorico [155]

Answer:

3x3-45÷(4+1) is 0.

Step-by-step explanation:

We have to do order of operations so we follow PEMDAS:

P is for Parentheses so we do what's in parentheses first:

(4+1)=5

E is for Exponents but we don't have exponents.

Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:

45÷5=9

We now have multiplication:

3x3=9

Now we have A and S for addition and subtraction

We don't have addition so we'll do subtraction:

9-9=0

The final answer is 0.

Hope this helps! :)
