The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD?

alexdok [17]

$(y-3)=-2(x-4) \\ y-3 = -2x+8 \\ y=-2x+11$
Slope: -2

NOTE: The line perpendicular to line $y=mx+b$ has a slope $-\dfrac{1}{m}$ .

So your slope is $-\dfrac{1}{-2}=\dfrac{1}{2}$ - 1 over 2 (Answer a)

Answer:

144°

Step-by-step explanation:

We are asked to convert 4π/5 radians to degrees.

#We know that:

$1 \ rad= 57.296\textdegree =180/\pi$

Therefore, we multiply 4π/5 radians by 180/π to get its degrees equivalent:

$=\frac{4\pi}{5}\ rad\times \frac{180}{\pi}\\\\=144\textdegree$

Hence, the degrees equivalent of 4π/5 rad is 144°.

a term in an arithmetic sequence is 488. the first term of the sequence is 7 and the common difference is 13. find the term numb

lisabon 2012 [21]

Answer: the term number is 38

Step-by-step explanation:

Let the number of the term be x

The value of the xth term = 488

In an arithmetic sequence, the terms differ by a common difference, d. This means that the difference between two consecutive terms, d is constant.

The formula for the nth term is

Tn = a + (n-1)d

Where

Tn = the nth term of the arithmetic sequence

a = the first term of the arithmetic sequence.

d = common difference.

From the information given,

a = 7

d = 13

We are looking for the xth term.

Tx = 488 = 7 + (x-1)13

488 = 7 + 13x - 13

Collecting like terms on the left hand side and right hand side of the equation,

13x = 488 -7 + 13

13x = 494

x = 38

The value of the 38th term is 488.
