Answer:

6,common difference

nth term== 6n-1

Step-by-step explanation:

an=a1+(n-1)d -formula to find nth term

to find common difference subtract 11-5=6,or 17-11=6

now substitute an=nth term

a1=1st term in sequence

d=common difference

an=6(+n-1)+5

distribute

an=6n-6+5

an=6n-1

hope this helps

Common difference is +6 and I think nth term is 5 (pretty sure it's always the first term) and the second one im not so sure about I'm sorry.

The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases. What is the volume of

Brums [2.3K]

The complete question in the attached figure

we know that
[volume of a cone]=[area of the base]*h/3
[area of the base]=22*10/2-------> 110 units²
h=19.5 units
[volume of a cone]=[110]*19.5/3------> 715 units³

[volume of a triangular prism]=[area of the base]*h
[area of the base]=110 units²
h=25 units
[volume of a a triangular prism]=[110]*25------------> 2750 units³

[volume of a the composite figure]=[volume of a cone]+[volume of a a triangular prism]
[volume of a the composite figure]=[715]+[2750]-------> 3465 units³

the answer is
The volume of a the composite figure is 3465 units³

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)?

salantis [7]

Answer:

tg (-60°) = -√3

Step-by-step explanation:

We can solve this, using a calculator, but I would like you to understand this problem without the use of that.

This is trigonometry, so first we need to know the value of pi in trigonometry.

The value of π is equals to 3.14 but in this case, we need to take the value of π in degrees. This value is 180°.

Now, the following step is replace this value into the expression:

tg (-180/3) = tg (-60°)

So the actual value we are looking for is tangent of 60°. Tangent can be calculated using the expression with the sin and cosine so:

tg = sin/cos

so to get the value of tg 60°:

tg 60° = sin 60° / cos 60°

The value of sin 60° = √3/2, while the value of cos 60° = 1/2, so replacing both values above, we can get the value of tg 60°:

tg 60° = (√3/2) / (1/2) both 2 gets cancel out so:

tg 60° = √3 / 1

tg 60° = √3

As we want tg(-60) the real value would be:

tg (-60°) = -√3

So the answer would be option 1.

Solve each system of inequalities by graphing. <br><br> x-2y<3<br> 2x+y>8

salantis [7]

Not easy to graph but

multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton

2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5

subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5

x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)
