Answer:

C) 19

Step-by-step explanation:

The two angles next to each other are complementary angles meaning they add up to 90°. We can use this information to solve for y:

3y + 2 + 31 = 90

3y + 33 = 90

3y = 57

y = 19

The paper is 16 cm by 34 cm to start with, so we started with area
.. (16 cm)*(34 cm) = 544 cm^2

A circle of diameter 16 cm has been removed. The area of that circle is
.. π*(d/2)^2 = 3.14*(16 cm/2)^2 = 200.96 cm^2

Then the area of the paper that remains is
.. 544 cm^2 -200.96 cm^2
.. = 343.04 cm^2

Find an equation for the nth term in the following sequence:<br> 2, 8, 32, 128, 512...
seraphim [82]

Answer:

a_n = 2(4) ^{n-1}

Step-by-step explanation:

The sequence shown matches that of a geometric sequence of radius 4. To prove it, divide the term \frac{a_{n + 1}}{a_n} and check that \frac{a_{n + 1}}{a_n}=4

Then the formula that represents this sequence is:

a_n = a_1(r)^{n-1}

Where a_1 is the first term of the series = 2 and r is the radius of convergence = 4.

Then the equation is:

a_n = 2(4) ^{n-1}
