Special Right Triangles

Mathematics
1 answer:
Leokris [45]3 years ago
7 0

Answer:

first option

Step-by-step explanation:

Using the sine/ cosine ratios in the right triangle and the exact values

sin30° = \frac{1}{2} , cos30° = \frac{\sqrt{3} }{2}

sin30° = \frac{opposite}{hypotenuse} = \frac{x}{32} = \frac{1}{2} ( cross- multiply )

2x = 32 ( divide both sides by 2 )

x = 16

----------------------------------------------------------

cos30° = \frac{adjacent}{hypotenuse} = \frac{y}{32} = \frac{\sqrt{3} }{2} ( cross- multiply )

2y = 32\sqrt{3} ( divide both sides by 2 )

y = 16\sqrt{3}

An account is opened with an initial deposit of \$3,000 and earns 4.1\% interest compounded quarterly What the account worth in
vfiekz [6]

Answer:

After 2 years the account worth will be $3225

Step-by-step explanation:

Initial Deposit (Principal Amount P) = $3000

Rate r = 4.1% = 0.041

Compounded quarterly = n = 4

Time t = 2 years

We need to find future value A

The formula used is: A=P(1+\frac{r}{n})^{nt}

Putting values in formula and calculating A

A=P(1+\frac{r}{n})^{nt}\\A=3000(1+\frac{0.041}{4})^{4*2} \\A=3000(1+0.01025)^{8} \\A=3000(1.01025)^8\\A=3000(1.085)\\A=3225

So, After 2 years the account worth will be $3225

the length of a cll is 2/3 mm. if the area of the cell is 1/12 square mm, what is the width of the cell
erastovalidia [21]

The width of a cell with the length (l) of the cell is \frac{2}{3} mm and area (A) of the cell is \frac{1}{12} mm² is \frac{1}{8}.

Given that, the length (l) of the cell is \frac{2}{3} mm and area (A) of the cell is \frac{1}{12} mm².

We need to find the width of the cell.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle is the product of its length and width. So, the area of the rectangle = Length×Width square units.

Now, the area of a cell = \frac{2}{3} ×Width=  \frac{1}{2} mm².

⇒Width=\frac{\frac{1}{12} }{\frac{2}{3} } ={\frac{1}{12} \times {\frac{3}{2}=\frac{1}{8}

Therefore, the width of a cell with the length (l) of the cell is \frac{2}{3} mm and area (A) of the cell is \frac{1}{12} mm² is  \frac{1}{8}.
