Mathematics

The perimeter is the length of the outside of an object. So for just one of those squares it would be 4. Or a 2x2 would be 8.

In this case you have 20 squares. Five of which two sides are exposed. All you need to do is count the outside lines

Your answer is 21ft.

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
The perimeter, P, is:
P=x+x+y+y

P=2x+2y

P=2(x+y)

Ave had a rectangular garden that is shown below. The garden's area is 32 square feet. The length of the width is 4 feet. What i
Arlecino [84]

Answer:

The length of Ave's garden is 8 feet.

Step-by-step explanation:

The area of a rectangle can be calculated by:

              A = l × w

Where; A represents the area, l the length and w, width.

Thus from the question,

          32 =  l × 4

           l = 32 /4

           l = 8

Therefore, the length of the garden required is 8 feet.

Solve the equation in the interval 0 to 2pi.
galben [10]

Answer:

You don't need to single out \cos \theta to solve this question.  

To solve:

\begin{aligned}3 \cos 4 \theta & = -2\\\\\cos 4 \theta & = -\dfrac{2}{3}\\\\4 \theta & = \cos^{-1}\left( -\dfrac{2}{3\right)}\\\\\implies 4 \theta & =2.30053... \pm 2 \pi n, -2.30053...\pm 2 \pi n\\\\\theta & =\dfrac{2.30053...}{4} \pm \dfrac{\pi n}{2}, -\dfrac{2.30053...}{4}\pm \dfrac{\pi n}{2}\end{aligned}

So for the given interval 0\leq \theta \leq 2 \pi

\implies \theta =0.575, 2.146, 3.717, 5.288, 0.996, 2.566, 4.137, 5.708\:\:(\sf 3 \: d.p.)

(As confirmed by the attached graph)

I forgot how to multiply fractions cause its been so long...some one help! 3/4÷4/5.
Novay_Z [31]
Well, you're asking for a refresher on multiplying fractions, but then the
example at the end of your question uses the symbol for division, not
multiplication.  So I'll just give you the rules for both operations, and let you
choose the one you need.

To multiply fractions:

-- Multiply the two numerators. 
   Write the product on top of a new fraction.

-- Multiply the two denominators. 
   Write the product on the bottom of the new fraction.

-- The new fraction is the product of the two original fractions.

To divide fractions:

-- Invert (flip) the second fraction.

-- Then multiply them.

-- Their product is actually the quotient of the two original fractions.
