* Jenny marked on a coordinate plane all points with the first coordinate an integer between −12 and 7 and the second coordinate

Nat2105 [25]

Answer:

Jenny marks 414 different points on the coordinate plane.

Step-by-step explanation:

A point on a coordinate plane is represented by (x, y)

The possible values of x include all the integers between -12 and 7; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6.

The possible values of y include all the integers between -12 and 12; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

This means that each x-value can take on each y-value.

There are 18 x-values and 23 y-values.

Each x-value can form 23 different coordinates with all the available y-values.

18 x-values will form 18 × 23 different coordinates with the all the available y-values.

The total number of points that Jenny marks = 18 × 23 = 414.

Hope this Helps!!!

Over 30 points please help me i need it bad

pashok25 [27]

Distance formula: d= square root of (x2-x1)^2+(y2-y1)^2
(3,5) (7,3)
d= square root of (7-3)^2+(3-5)^2
d= square root of (4^2)+(-2^2)
d= square root of 16+4
d= square root of 20
d=4.47...rounded= 4.5
Hope this helped!

Which function has the domain x>or= -11

iogann1982 [59]

I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
$y = \sqrt{x + 11}$
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.

Which expression represents the composition [g o f o h](x) for the functions below?

asambeis [7]

Answer: 16875x³-13500x²+3600x-320

Step-by-step explanation:

[gοfοh](x) means g(f(h(x))). So you plug in h(x) into f(x) and that into g(x).

f(3x)=5(3x)-4=15x-4

g(f(3x))=5(15x-4)³

g(f(3x))=5(3375x³-2700x²+720x-64)

g(f(3x))=16875x³-13500x²+3600x-320

Find the area of a square with a diagonal of 4cm.

inessss [21]

Let the side length be s. Then sqrt(s^2+s^2) is the length of the diagonal.

sqrt(2s^2) = 4 cm, so 2s^2 = 16 cm, and s^2 = 8, so that s = 2sqrt(2).

The area of this square is s^2, which here is 4(2), or 8 square units (answer)
