Angle E is from A to E

see, the 0 is on the right

A pool measures 100 meters by 100 meters. A toddler, inside the pool, throws a ball and it lands 60 centimeters from one edge of

ratelena [41]

We need to covert 100 m to cm
1m=100 cm
100m=10000cm
so if he threw it and it landed 60 from on end, the pool is still same width/legnth so
it depends on whether it landed in the pool 60 cm away from edge or outside of the pool, 60 cm from edge
if in go to AAAAAAAAAA
if out got to BBBBBBB

AAAAAAAAAAAAAAAA
60+distance to other edge=width of pool=10000
60+d=10,000
subtract 60
9940 cm

BBBBBBBBBB
60+width=distance
60+10,000
10,060 cm

if it landed IN the pool 60 cm away from edge, answer is 9940cm
if it landed OUTSIDE of the pool, 60 cm from edge, answer is 10,060 cm

Find the volume of the solid whose base is the region Ix I Iy I < 1 and whose vertical cross sections perpendicular to the y-

gavmur [86]

Answer:

volume of the solid = $\frac{\pi }{3}$

Step-by-step explanation:

As given , the region : |x| + |y| $\leq$ 1

when y $\geq$ 0 ,

|x| + y = 1

⇒|x| = 1 - y

when y ≤ 0 ,

|x| - y = 1

⇒|x| = 1 + y

The given region is the rectangle with sides (0, 5) , (0, -5), (5, 0), (-5, 0)

As given , the vertical cross section are semicircle

As we know that the area of semi circle = $\frac{1}{2}$ $\pi x^{2}$

Now,

Volume = $\int\limits^0_-1 {\frac{\pi }{2} (1+y)^{2} } \, dy$ + $\int\limits^1_0 {\frac{\pi }{2} (1-y)^{2} } \, dy$

= $\frac{\pi }{2} (\frac{(1+y)^{3} }{3} )$ - $\frac{\pi }{2} (\frac{(1-y)^{3} }{3} )$

= $\frac{\pi }{6}$ [1-0] - $\frac{\pi }{6}$ [0-1]

= $\frac{\pi }{6} + \frac{\pi }{6} = 2\frac{\pi }{6} = \frac{\pi }{3}$

⇒volume of the solid = $\frac{\pi }{3}$

Can some hell me understand foil <br> for (4x-3)(x+11)

Naddik [55]

Answer:

4x² + 41x - 33

Step-by-step explanation:

F in foil stands for 'first'; take the first value in each bracket and multiply them together. So 4x × x = 4x²
O in foil stands for 'outside'; take the outermost values from each bracket and multiply them together. So 4x × 11 = 44x
I in foil stands for 'inside'; take the innermost values for each bracket and multiply them together. So -3 × x = -3x
Finally, L in foil stands for 'last'; take the last value in each bracket and multiply them together. So -3 × 11 = -33
Now, we can put this all together and simplify: 4x² + 44x - 3x - 33 → 4x² + 41x - 33.

Hope this helps!

Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$
