Write the first four terms of the sequence. rule start at 5 1/2, add 1 1/5
Hitman42 [59]

Answer:

5\frac{1}{2},6\frac{7}{10},7\frac{9}{10},9\frac{1}{10}

Step-by-step explanation:

The first term of the sequence is

a_1=5\frac{1}{2}

To find the second term add 1\frac{1}{5} to the first term;

a_2=5\frac{1}{2}+1\frac{1}{5}=6\frac{7}{10}

To find the third term add 1\frac{1}{5} to the second term;

a_3=6\frac{7}{10}+1\frac{1}{5}=7\frac{9}{10}

To find the fourth term add 1\frac{1}{5} to the third term;

a_4=7\frac{9}{10}+1\frac{1}{5}=9\frac{1}{10}

The first four terms are

5\frac{1}{2},6\frac{7}{10},7\frac{9}{10},9\frac{1}{10}

Find the zeros of the function. f(x) = 4x3 - 12x2 - 40x
mote1985 [20]
First take out the GCF which is 4x

 4x (x^2 - 3x - 10) = 0

4x(x - 5)(x + 2) = 0

4x = 0  so x = 0

x - 5 = 0 so x = 5

x+2 = 0 so x = -2

zeros are  -2, 0 and 5

How long is JK?
-Dominant- [34]

Answer:

C) 3 times the sq root of 3

Step-by-step explanation:

In a right angle triangle, the COS is definned as the ajacent side over the hypotenuse. So

COS 60 = JK/JL

COS 60 = JK/(6*sq root 3)

.5 = JK/(6*3**1/2)

JK = .5 *(6*3**1/2)

JK = 3*3**1/2
