For the function F defined by F(x) = x2 – 2x + 4, find F(| — 4|).

Lostsunrise [7]

F(x)=x^2-2x+4

$\\ \sf\longmapsto F(|-4|)$

$\\ \sf\longmapsto F(4)$

$\\ \sf\longmapsto 4^2-2(4)+4$

$\\ \sf\longmapsto 16-8+4$

$\\ \sf\longmapsto 8+4$

$\\ \sf\longmapsto 12$

-3r-8(8r+8)=-9(-4+9r)

natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)

A coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the c

koban [17]

Answer:

You would get tails 75 times, or 75:200

Step-by-step explanation:

5:8 = x:200

multiply 8 by 25 to get 200

multiply 5 by 25 to get x (125)

Probability to get heads is 125 so subtract 200 by 125

200 - 125 = 75
