It has six sides and six angles.

Lengths of all the sides and the measurement of all the angles are equal.

The total number of diagonals in a regular hexagon is 9.

The sum of all interior angles is equal to 720 degrees, where each interior angle measures 120 degrees.

puteri [66]

Answer:Answer:

F = 0.84 [N]

Explanation:

In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.

F = m*a

where:

F = force [N]

a = acceleration = 1.4[m/s^2]

m = mass = 0.6 [kg]

F = 0.6*1.4

F = 0.84 [N]

Travka [436]

Answer:

$1,175.34

Step-by-step explanation:

To solve for the total amount after 7 years. We need to use the formula:

$A = P(1+\dfrac{r}{n})^{nt}$

Let's first break down all the variables that we have.

P = 480

r = 13% or 0.13

n = 4 (Quarterly)

t = 7 years

Now we simply substitute the values into the formula.

$A = P(1+\dfrac{r}{n})^{nt}$

$A = 480(1+\dfrac{0.13}{4})^{4(7)}$

$A = 480(1+\dfrac{0.13}{4})^{28}$

$A = 480(1+0.0325)^{28}$

$A = 480(1.0325)^{28}$

$A = 480(2.45)$

$A = $1,175.34$

The account will have $1,175.34 after the 7 year period.

Priya has planted a garden shaped like a right triangle. She knows that one leg of the triangle is 11 meters long and that the a

olga55 [171]

Answer:

She will need 41.22 meters.

Step-by-step explanation:

She knows that one leg of the triangle is 11 meters long and that the angle formed by that leg and the hypotenuse is 50 degrees .

The leg is adjacent to the hypothenuse. We know that the cosine of an angle $\theta$ is given by:

$\cos{\theta} = \frac{l}{h}$

In which l is the length of the adjacent side and h is the hypothenuse.

Considering that we have $\theta = 50, l = 11$ , we can find the hypothenuse.

Looking at a calculator, the cosine of 50 degrees is 0.6428.

$0.6428 = \frac{11}{h}$

$0.6428h = 11$

$h = \frac{11}{0.6428}$

$h = 17.11$

The other leg:

In a right triangle, with legs $l_1$ and $l_2$ , and hypothenuse h, the pythagorean theorem states that:

$l_1^2 + l_2^2 = h^2$

We already have one of the legs and the hypothenuse, so:

$11^2 + l^2 = 17.11^2$

$l^2 = 17.11^2 - 11^2$

$l = \sqrt{17.11^2 - 11^2}$

$l = 13.11$

How many meters will she need?

This is the perimeter of the garden, which is the sum of its dimensions, of 11 meters, 13.11 meters and 17.11 meters. So

$P = 11 + 13.11 + 17.11 = 41.22$

She will need 41.22 meters.
