Answer:

a = 1/8

b = 8

Step-by-step explanation:

a (1/2) ^3 = (1/2) *(1/2) * (1/2) = 1/8

b( 1/2 ) ^ -3  The negative exponent means 1 / (1/2)^3  = 1/ (1/8) = 8

Find the coefficient of x^7 in the expansion of (3x+4)^11
devlian [24]

Use the binomial theorem:

(a+b)^n=\displaystyle\sum_{k=0}^n\binom nka^{n-k}b^k

In this case,

(3x+4)^{11}=\displaystyle\sum_{k=0}^{11}\binom{11}k(3x)^{11-k}4^k

The x^7 term occurs for k=4:

\dbinom{11}4(3x)^{11-4}4^4=\dfrac{11!}{4!(11-4)!}3^74^4x^7=184,757,760x^7

How do I solve #7? do i add all the angles together like a normal triangle and make it equal to 180?
kobusy [5.1K]

Answer:

126 degrees

Step-by-step explanation:

Triangle: y = 180 - (5x + 4x)

Straight angle: y = 180 - (4x + 30)

180 - (5x + 4x) = 180 - (4x + 30)

5x + 4x = 4x + 30

5x = 30

x = 6

Angle:

y = 180 - (5x + 4x)

y = 180 - 9x

y = 180 - 9(6)

y =  126

What is the equation of the line, in point-slope form, that passes through the points (-7, -10) and (-6, -8)?
Masja [62]

Answer:

not sure if that is the Answers

The equation of a line is y = mx where m is the slope. That line passes through the origin. If you want it to pass through some point (a, b) you subtract the coordinates like this: y - b = m (x - a). That is the point-slope form, and you can rewrite it in other forms if it is convenient. You may do this with any point on the line.
