To convert radians to degrees, make use of the fact that pi radians equals one half circle, or 180º.

This means that if you divide radians by pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.

So, to convert radians to degrees, multiply by 180/pi, like this:

Degrees= radians X 180/pi

Fill in the gaps in the arithmetic sequence -3, _ ,_ , _, _, _ 12

lord [1]

Answer:

-0.5, 2, 4.5, 7, 9.5

Step-by-step explanation:

The given terms are 6 apart, so the common difference is 1/6 of their difference:

d = (12 -(-3))/6 = 15/6 = 5/2 = 2.5

Add 2.5 to each term to get the next one. Then the sequence is ...

-3, -0.5, 2.0, 4.5, 7.0, 9.5, 12

How to factor that polynomial

professor190 [17]

<h3>(1 + 5y)(1 - 5y) is the fully factored form of this polynomial.</h3>

This polynomial can be factored using difference of squares.

This polynomial is in the form of a^2 - b^2 = (a + b)(a - b)

Because 1 * 1 = 1, we can use this formula to simplify this polynomial.

1 - 25y^2 = (1 + 5y)(1 - 5y)

We can use FOIL to verify this.

(1 + 5y)(1 - 5y)

1 - 5y + 5y - 25y^2

1 - 25y^2

Find the sum of the following series. Round to the nearest hundredth if necessary,

Aneli [31]

Answer:

$sum = \frac{a( {r}^{n - 1} )}{r - 1} \\ : but \: l = a( {r}^{n - 1} ) \\ 49152 = 3( {2}^{n - 1} ) \\ 16384 = {2}^{n - 1} \\ {2}^{n} = 32768 \\ {2}^{n} = {2}^{15} \\ n = 15 \\ \therefore \: sum = \frac{3(2 {}^{15 - 1}) }{15 - 1} \\ = \frac{49152}{14} \\ = 3510.9$

I need the answer ASAP please

lara [203]

a $\leq$ 7

because 4a + 7 - 7 $\leq$ 35 - 7

equals 4a $\leq$ 28

and 4a/4 $\leq$ 28/4

equals a $\leq$ 7
