Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. In the equation√n+5
Yuki888 [10]

Answer:

n = 59

Step-by-step explanation:

The given equation of n is \sqrt{n + 5} - \sqrt{n - 10} = 1 and we have to solve it for n.

\sqrt{n + 5} - \sqrt{n - 10} = 1 ........... (1)

⇒ \frac{(n + 5) - (n - 10)}{\sqrt{n + 5} + \sqrt{n - 10}} = 1  

{Rationalizing the numerator}

⇒ \sqrt{n + 5} + \sqrt{n - 10} = 15 .............. (2)

Now, adding (1) and (2) we get

2\sqrt{n + 5} = 16

⇒ n + 5 = 64 {Squaring both sides}

⇒ n = 59 (Answer)

what is the circumference of a circle that has a radius of 8 units use 3.14 (pie) and round to the nearest hundredth
SashulF [63]

Remember that the formula for the circumference, C, of a circle is:

C = d \pi


In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,

d = 2 \cdot 8 = 16,

and we can say the circumference of our circle is:

C = 16 \cdot 3.14 = 50.24 \,\textrm{units}


The circumference of our circle is 50.24 units.


<em>Also, a little side note not relating to the question:</em>

<em>Remember that \pi is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.</em>

15 points!
Phantasy [73]

Hi there! You are provided with two points, this is all you need to calculate the line's slope.


The equation for slope is:

\frac{y2 - y1}{x2 - x1}

\frac{10 - 8}{3 - 7} = -\frac{2}{4}

Slope: -2/4


Point slope form, or y-y1 = m(x - x1). All we have to do is take the x and y coordinates of either point, as well as the slope, and plug them into the equation.

y - 10 = -2/4(x - 3)


Write the equation in slope-intercept form (y=mx+b)

y - 10 = -2/4(x-3)\\y = -2/4(x-3) + 10\\y = -2/4x + 1.5 + 10\\y = -2/4x + 11.5


A) -2/4

B) y - 10 = -2/4(x - 3)

C) y = -2/4x + 11.5
