Answer: Infinite solutions

Step-by-step explanation: 3x -7 = 3(x-3)+2

                                             3x + -7 = (3)(x) + (3)(-3) + 2

                                             3x + -7 = 3x + -9 + 2

                                             3x - 7 = (3x) + (-7)

                                             3x -7 - 3x = 3x - 7 - 3x

                                             -7 + 7 = -7 + 7

                                             0 = 0

lubasha [3.4K]
Answer: About 12.083



Explanation:
In order to solve this you would use Pythagorean theorem.

You are given the length of the two legs (5 and 11)

So by plugging in 5 and 11 into A Squared plus B Squared = C Squared, you get that C^2= 146.

By finding the square root of both sides you get square root of 146, which is approximately 12.803

(a) Starting with the geometric series [infinity] xn n = 0 , find the sum of the series [infinity] nxn − 1 n = 1 , |x| < 1.
Mila [183]

Let <em>f(x)</em> be the sum of the geometric series,

f(x)=\displaystyle\frac1{1-x} = \sum_{n=0}^\infty x^n

for |<em>x</em>| < 1. Then taking the derivative gives the desired sum,

f'(x)=\displaystyle\boxed{\dfrac1{(1-x)^2}} = \sum_{n=0}^\infty nx^{n-1} = \sum_{n=1}^\infty nx^{n-1}

Which expression is equivalent to<br> (X^1/4 y^16)^1/2?
lawyer [7]

Answer:

x^{\frac{1}{8} } y^{8}

Step-by-step explanation:

Given :

(x^\frac{1}{4}  y^{16} )^{1/2}

Now,

(x^\frac{1}{4}  y^{16} )^{1/2}\\x^{\frac{1}{8} } y^{8}

Therefore, expression is equivalent to x^{\frac{1}{8} } y^{8}

Sara jumps off a diving board that is 6 feet above the surface of the water her height above the surface of the water h in feet
Flauer [41]
Well when she hits the water h=0 so

2t^2-t-6=0  factor

2t^2-4t+3t-6=0

2t(t-2)+3(t-2)=0

(2t+3)(t-2)=0, since t>0

t=2 seconds...

However it should be noted that h(t)=-2t^2+t+6 implies that

v(t)=dh/dt=-4t+1 and

a(t)=dv/dt=-4

Since this is a free fall equation, this would suggest that the acceleration due to gravity is -4, whether that is supposed to be -4ft/s^2 or -4m/s^2, it certainly is not on this planet! :D  If it is -4ft/s^2 it could be on the Moon or if it is -4m/s^2 it could be on Mars.
