Given the fuction h (x) = x^2 + 2x -3, find the value of h (2) - h (-4)

Anettt [7]

Answer:-

Step-by-step explanation:

h(x) = x^2 + 2x -3

x = 2

h(2) = 2^2 + 2(2) - 3

h(2) = 4 + 4 - 3

h(2) = 8-3

h(2) = 5

x = - 4

h(-4) = (-4)^2 + 2(-4) - 3

h(-4) = 16 - 8 - 3

h(-4) = 16 - 11

h(-4) = 5

========

h(2) - h(-4)

5 - 5

An experiment consists of choosing objects without regards to order. Determine the size of the sample space when you choose the

sdas [7]

Answer:

$n= 75, 582$

$n= 2300$

$n = 253$

Step-by-step explanation:

Generally the size of the sample sample space is mathematically represented as

$n = \left N } \atop {}} \right. C_r$

Where N is the total number of objects available and r is the number of objects to be selected

So for a, where N = 19 and r = 8

$n = \left 19 } \atop {}} \right. C_8 = \frac{19 !}{(19 - 8 )! 8!}$

$= \frac{19 *18 *17 *16 *15 *14 *13 *12 *11! }{11 ! \ 8!}$

$n= 75, 582$

For b Where N = 25 and r = 3

$n = \left 25 } \atop {}} \right. C_3 = \frac{25 !}{(19 - 3 )! 3!}$

$= \frac{25 *24 *23 *22 ! }{22 ! \ 3!}$

$n= 2300$

For c Where N = 23 and r = 2

$n = \left 23 } \atop {}} \right. C_2 = \frac{23 !}{(23 - 2 )! 2!}$

$= \frac{23 *22 *21! }{21 ! \ 3!}$

$n = 253$

Please help! i was wondering how you would solve this question!

Answer: C. 150 km²

<u>Step-by-step explanation:</u>

Use similar triangle proportion to find x:

$\dfrac{x}{4.5}=\dfrac{15.3+7.4}{7.4}\\\\\\x=\dfrac{4.5(22.7)}{7.4}\\\\\\x=13.8\\\\\text{Notice that x is the diameter of the circle}\implies r=\dfrac{13.8}{2}=6.9\\\\\\\text{Find the area of the circle using }A=\pi r^2\\A=\pi (6.9)^2\\\\.\ =\pi (47.6)\\\\.\ =149.6\\\\.\ \approx150$
