Csc is the inverse of sin. This means the formula in regards to a triangle for csc is h/o, unlike o/h for sin. csc can also be knows as 1/sin.

Veseljchak [2.6K]
The volume of rectangular prism is the product of its length, width and height. 
So the volume V of prism with length 1 \frac{1}{4} yards, width 2 \frac{1}{2} yards and height of 4 yards will be:

V=1 \frac{1}{4} * 2 \frac{1}{2} *4 \\  \\ 
V=  \frac{5}{4}* \frac{5}{2}*4 \\  \\ 
V= \frac{25}{2} \\  \\ 
V=12 \frac{1}{2}

Thus the volume of prism as a mixed number in simplest form will be 12 \frac{1}{2} cubic yards

How do you Use Trigonometry to find length
Ivan

Right Triangles and the Pythagorean Theorem

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.

The side opposite the right angle is called the hypotenuse (side c in the figure).

Emilio throws a marshmallow into the air from his balcony. The height of the marshmallow (in feet) is represented by the equatio
irinina [24]

Answer:

Step-by-step explanation:

The height of the marshmallow (in feet) is represented by the equation h=−16t2+8t+48,

where t is the time (in seconds) after he throws the marshmallow.

The equation is a quadratic equation. When the marshmallow hits the ground, its height from the ground will be zero. Therefore

−16t^2+8t+48 = 0

- 2t^2 + t + 6 = 0

Multiplying through by the negative sign. It becomes

2t^2 - t - 6 = 0

2t^2 + 3t - 4t - 6 = 0

t(2t + 3) - 2(2t + 3) = 0

(t - 2)(2t + 3) = 0

t - 2 = 0 or 2t + 3 = 0

t = 2 or t = - 3/2

The time cannot be negative

So it will take 2 seconds to hit the ground

Help! plz and thx! what is 4:08 - 1:15 = ?:? plz, help WITH AND WITHOUT REGROUPING thx!!!!!!! I will give u the brainiest! plz a
sergejj [24]

Answer:

2:53

Step-by-step explanation:

I believe that you are subtracting times here, so have in mind that if the first number indicates hours, and the second number minutes, and you are asked to subtract more of one quantity (minutes for example) than what you have, you will need to convert some of the hours into minutes.

Recall that 1 hour equals 60 minutes.

in the difference   4:08 minus 1:15, you sre expected to subtract minutes from minutes and hours from hours. Now the number of minutes you need to subtract from 08 is 15 (larger than 08) so we need to convert 1 hour into minutes in the first expression, and then (with enough minutes to deal with), we can subtract:

4:08 is the same as 3:68 where we converted 1 hour to 60 minutes and added those 60 minutes to the existing 8 .

Now the difference can be performed:

3:68 - 1:15 = (3-1):(68-15) = 2:53
