Answer:

1/2 + 1/3 = 5/6

Step-by-step explanation:

you would take a common denominater which in this case is 6 as it is a multiple of both 2 and 3.

you would multiply times 3 for the first fraction ad then by 2 in the second fraction. Both on the denominator and the numerator.

\frac{1}{2}  which   becomes    \frac{3}{6}  and     then \frac{1}{3} which       becomes  \frac{2}{6}.

3/6 +2/6 = 5/6

Find the area and circumference of the circle below:<br> Diameter - 14 cm
MAVERICK [17]

Answer:

<em>Area : 153.86cm</em>

<em>Circumference:  43.96cm</em>

Step-by-step explanation:

<u><em>To Find:</em></u>

<em>Area __ cm</em>

<em>Circumference__ cm</em>

<u><em>Given:</em></u>

<em>Since, it given that the Diameter is 14 cm</em>

<em>Diameter which is any straight line segment that passes through the center of the circle.</em>

<em>Radius which is half of diameter</em>

<u><em>Note: </em></u>

<em>A = πr  ²                                                          {Area Formula}</em>

<em>C = rd                                                           {Circumference Formula}</em>

<em>pi also known as π = 3.14                            {approximately }</em>

<em>"r " means Radius</em>

<em>"d " means diameter</em>

<em>c = circumference</em>

<em>a = area</em>

<u><em>Solve:</em></u>

<em>A = πr  ²</em>

<em>Since radius is half of the diameter then...</em>

<em>14/2 = 7</em>

<em>Radius = 7</em>

<em>A = 3.14(7)²                                   { (7)² means 7 × 7 </em><u><em>Not </em></u><em>7 × 2 }</em>

<em>A = 3.14(49)                                  { 7 × 7 = 49}</em>

<em>A = 153.86</em>

<em>C = rd       </em>

<em>C = 3.14(14)</em>

<em>C = 43.96</em>

<em>Area : 153.86cm</em>

<em>Circumference:  43.96cm</em>

Find the sum of the first five terms using the geometric series formula for the sequence 1/2, -1,2,-4…
sammy [17]

The sum of the first five terms is 11/2

<h3>How to determine the sum?</h3>

The series is given as:

1/2, -1,2,-4…

Calculate the common ratio of the series using

r = -4/2

Evaluate

r = -2

The sum is then calculated as:

S_n = a\frac{1 - r^n}{1 - r}

This gives

S_n = \frac{1}{2} * \frac{(1 - (-2)^5}{1 + 2}

Evaluate

S_n = \frac{1}{2} * \frac{33)}{3}

Evaluate

S_n =\frac{11}{2}

Hence, the sum of the first five terms is 11/2

Simplify: 20 sin(2x) cos(2x)
alexandr1967 [171]
Use the the double angle formula:
sin(2A)=2sin(A)cos(A)

substitute 2x for A, then
20sin(2x)cos(2x)=10(sin(2(2x))cos(2(2x))=10sin(4x)
