10. The volume of the triangular prism is $V=A_{base}\cdot H=\dfrac{1}{2} height \cdot base\cdot H$ , then

$V=\dfrac{1}{2} \cdot 4\cdot 3.5\cdot 3.3=23.1$ .

11. The volume of the triangular pyramid is $V=\dfrac{1}{3}A_{base}\cdot H=\dfrac{1}{3}\cdot \dfrac{1}{2} height \cdot base\cdot H$ , then

$V=\dfrac{1}{3}\cdot \dfrac{1}{2} \cdot 4\cdot 3.5\cdot 3.3=7.7$ .

12. They have common base (common triangle). y=7.7, r=23.1, then r:y=23.1:7.7=3.

13. See 10 and 11 for notations in symbols.

A garden store has the following miscellaneous bulbs in a basket:

ArbitrLikvidat [17]

Okay. Since we know that the customer before them bought one of each type of bulb, we can subtract one bulb from each type so now, here is what the store has:

5 amaryllis

6 daffodils

3 lilies

2 tulips

Next, let’s find the probability of the customer picking an amaryllis.

We know there are 5 amaryllis, so we can put that as the numerator.

Next, we have to add up all the flowers to get the denominator.

5+6+3+2

I got 16.

So now we have 5/16

So, that is our answer! 5/16, or as a decimal 0.3125, or as a percentage 31.25%.

Hope this helps! Comment if you have any questions! :)

When h has value 4 calculate 5h -3

Lapatulllka [165]

5x4-3
5x4=20
so 20-3 = 17
your answer is 17.
You replace h with 4, then multiply 4 by 5 and then deduct 3 from the product.

How would you verify the trigonometric identity 2x = 2sinx cosx

dem82 [27]

Step-by-step explanation:

Hi, there!!

I hope you mean sin2x=2sinx . cosx

so, let's begin in a simple way; by adding, alright:

sin2x= sin(x+x) (as 2x=x+x).

now, let's use compound formula for sin,

so, we get:

sin (x+x)= sinx.cosx + cosx. sinx (as sin(A+B)=sin A. cosB + cosA . sinB)

or, sin (x+x)=2sinx.cosx (adding both).

Therefore, sin 2x = 2sinx. cosx.

Hope it helps..
