Given that the volume of a cube is 2744 cm cube find the length of its edge
bixtya [17]
Volume of cube =a^3
2744=a^3
by making prime factors of 2744
2*2*2*7*7*7=a^3
2^3*7*3=a^3
by taking cube root on both sides
2*7=a
14=a
so<span> the length of its edge =14</span>

The explicit rule for the arithmetic sequence shown in the graph is a↓n=9.5+2(n-1)
Virty [35]

Answer:

True.

Step-by-step explanation:

The explicit form for an arithmetic sequence is:

a_n=a_1+d(n-1)

where a_1 is the first term and d is the common difference.

The common difference here is 2 because the y's are going up by 2 while the x's are going up by 1.

Yes, the common difference is the slope.

So we have d=2.

The first term is 9.5 because that is what happens when x=1.

x is n.

y is a_n.

So the answer is true.

----

You can also verify by plugging in numbers for n and see if you get the outputs mentioned in the pairs given:

Let n=1:

a_1=9.5+2(1-1)

a_1=9.5+2(0)

a_1=9.5+0

a_1=9.5

Let n=2:

a_2=9.5+2(2-1)

a_2=9.5+2(1)

a_2=9.5+2

a_2=11.5

Let n=3:

a_3=9.5+2(3-1)

a_3=9.5+2(2)

a_3=9.5+4

a_3=13.5

Let n=4:

a_4=9.5+2(4-1)

a_4=9.5+2(3)

a_4=9.5+6

a_4=15.5

Let n=5:

a_5=9.5+2(5-1)

a_5=9.5+2(4)

a_5=9.5+8

a_5=17.5

Let n=6:

a_6=9.5+2(6-1)

a_6=9.5+2(5)

a_6=9.5+10

a_6=19.5

We have confirmed that we get all 6 of the mentioned points using the equation they gave.

Since you have a angle number of 23 and you see the tiny square that means it’s equal to 90 up top and add 23 and 90 together and then subtract that by 180 to get all 3 angles in the triangle and then just use that to find the other line that’s 180.

Find the missing value of X and Y.
Aneli [31]

Answer:

x = y = \sqrt{45}

Step-by-step explanation:

x^{2} + y^{2} = 30^{2}  \\x = y \\90 = \sqrt{45} +  \sqrt{45} \\\\ = 90
