We know that
circumference=pi*D
where D is the diameter
diameter=4 ft
circumference=4*pi ft
if one revolution is -------------> 4*pi ft
1320 rev-------------> x
x=1320*4*pi-----> x=5280*pi ft/hout

convert ft to miles
1 mile-----------> 5280 ft
so
5280*pi ft----------> is pi mile
5280*pi ft/hour------> is equal to pi mile/hour

the answer is the option
<span>a. pi</span>

For the parallelogram, fond the value of the variables. Show your work.

lisabon 2012 [21]

For this case, the first thing you should know is that the opposite sides of the parallelogram are the same.

Therefore, we have the following equations:

$3y-6 = 21\\5x + 2 = 17$

From equation 1 we have:

$3y = 21 + 6\\3y = 27$

$y = \frac{27}{3}\\y = 9$

From equation 2 we have:

$5x = 17 - 2\\5x = 15$

$x = \frac{15}{5}\\x = 3$

Answer:

the value of the variables are:

$y = 9\\x = 3$

Find the set of values of k for which the line y=kx-4 intersects the curve y=x²-2x at 2 distinct points?

Sonbull [250]

Answer:

$-6 < k < 2$

Step-by-step explanation:

Given

$y = x^2 - 2x$

$y =kx -4$

Required

Possible values of k

The general quadratic equation is:

$ax^2 + bx + c = 0$

Subtract $y = x^2 - 2x$ and $y =kx -4$

$y - y = x^2 - 2x - kx +4$

$0 = x^2 - 2x - kx +4$

Factorize:

$0 = x^2 +x(-2 - k) +4$

Rewrite as:

$x^2 +x(-2 - k) +4=0$

Compare the above equation to: $ax^2 + bx + c = 0$

$a = 1$

$b= -2-k$

$c =4$

For the equation to have two distinct solution, the following must be true:

$b^2 - 4ac > 0$

So, we have:

$(-2-k)^2 -4*1*4>0$

$(-2-k)^2 -16>0$

Expand

$4 +4k+k^2-16>0$

Rewrite as:

$k^2 + 4k - 16 + 4 >0$

$k^2 + 4k - 12 >0$

Expand

$k^2 + 6k-2k - 12 >0$

Factorize

$k(k + 6)-2(k + 6) >0$

Factor out k + 6

$(k -2)(k + 6) >0$

Split:

$k -2 > 0$ or $k + 6> 0$

So:

$k > 2$ or k $> -6$

To make the above inequality true, we set:

$k < 2$ or $k >-6$

So, the set of values of k is:

$-6 < k < 2$
