Use the law of cosines. Let x be the distance between the docks, which forms a third leg of a triangle for which the angle opposite it has measure 45 degrees. The other two legs have lengths 400 ft and 500 ft. So

x^2=400^2+500^2-2\cdot400\cdot500\cos45^\circ

\implies x\approx356.59\,\mathrm{ft}

Answer:

k = –10

Step-by-step explanation:

From the question given above, the following data were obtained:

f(x) = x³ – 6x² – 11x + k

Factor => x + 2

Value of K =?

Next, we shall obtained the value of x from x + 2. This is illustrated below:

x + 2 = 0

Collect like terms

x = 0 – 2

x = –2

Finally, we shall determine the value of k as illustrated below:

f(x) = x³ – 6x² – 11x + k

x = –2

Thus,

f(–2) = 0

x³ – 6x² – 11x + k = 0

(–2)³ – (–2)² – 11(–2) + k = 0

–8 – (4) + 22 + K = 0

–8 – 4 + 22 + K = 0

10 + k = 0

Collect like terms

k = 0 – 10

k = –10

Thus, the value of k is –10

5x-y=1/4 intercept form
MAVERICK [17]
5x - y = 1/4; this equation is written in slope - intercept form

Slope - Intercept form formula: y = mx + b

-Move '5x' to the left side of the equation
-Move 'y' to the right side of the equation

y = 5x - 1/4

Please help me!!!<br>What is the value of n?<br>2n = 8 + 4n<br>A)-4<br>B) 4<br>C)-4/3<br>D)4/3
erica [24]
To get the value of n u have to set n by itself, first we have to set teh smallest n to teh other side this will give you 0=8+2n now subtract the 8 from both sides because it is positive and the only way to get rid of a positive is with a negative this will give you -8=2n, now to set n by itself divide by 2 in both sides because in order to get rid of a multiplication you have to divide, this will give you n=-4, so your answer will be letter A

Hope this helps
