Answer:

t = 5.8

Step-by-step explanation:

Using the SINE rule:

t/sin(23) = 14/sin(108)

Therefore t = 14 / sin(108) * sin(23)

Therefore t = 5.7517463

or 5.8 to the nearest tenth.

How many times greater is 1 kilogram than 1 microgram?

Pani-rosa [81]

Using this table as a reference, you can see the following: A kilogram is 1,000 timeslarger than one gram (so 1 kilogram = 1,000 grams). A centimeter is 100 timessmaller than one meter (so 1 meter = 100 centimeters). A dekaliter is 10 timeslarger than one liter (so 1 dekaliter = 10 liters).

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), i

pychu [463]

Set the function to equal zero:

$-x^2 - 5x + 50 = 0$

To find the zeros, or solutions, to this problem, we will use the quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Plug the values into the equation:

$a = -1, b = -5, c = 50$

$x=\frac{5\pm\sqrt{-5^2-4(-1)(50)}}{2(-1)}$

$x=\frac{5\pm\sqrt{25+200}}{-2}$

$x=\frac{5\pm15}{-2}$

Solve for both plus and minus:

$\frac{5 + 15}{-2} = \frac{20}{-2} = -10$

$\frac{5 - 15}{-2} = \frac{-10}{-2} = 5$

$x = -10, x = 5$

The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.

The answer is 'x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.

A square is inscribed in a circle . If the area of the square is 9 inch square what is the ratio of the radius of the circle to

OLga [1]

Answer:

(√2)/2

Step-by-step explanation:

The ratio of the radius of the circle to the side of the inscribed square is the same regardless of the size of the objects.

The radius of the circle is half the length of the diagonal of the square. For simplicity, we can call the side of the square 1, so its diagonal is √(1²+1²) = √2 by the Pythagorean theorem. The radius is half that value, so is (√2)/2. The desired ratio is this value divided by 1.

Scaling up our unit square to one with a side length of 3 inches, we have ...

radius/side = ((3√2)/2) / 3 = (√2)/2

_____

A square with a side length of 3 inches will have an area of (3 in)² = 9 in².
