Is (0,0) a solution to this system y>=x^2+x-4; y<=x^2+2x+1

Answer:

It is a solution

Step-by-step explanation:

Check and see if (0,0) satisfies both inequalities.

The first inequality is:

y \geqslant  {x}^{2} + x - 4

When we put x=0, and y=0, we get:

0\geqslant  {0}^{2} + 0 - 4

\implies0\geqslant- 4

This part is true.

The second inequality is:

y \leqslant  {x}^{2}  + 2 x + 1

We put x=0 and y=0 to get:

0 \leqslant  {0}^{2}  + 2 (0) + 1

0 \leqslant 1

This part is also true.

Since the (0,0) not satisfy both, inequalities, it is a solution.

An adult brain is about 140 mm wide and divided into two sections (called "hemispheres" although the brain is not truly spherica
Sedbober [7]

Answer: 3.61×10^5 A

Step-by-step explanation: Since the brain has been modeled as a current carrying loop, we use the formulae for the magnetic field on a current carrying loop to get the current on the hemisphere of the brain.

The formulae is given below as

B = u×Ia²/2(x²+a²)^3/2

Where B = strength of magnetic field on the axis of a circular loop = 4.15T

u = permeability of free space = 1.256×10^-6 mkg/s²A²

I = current on loop =?

a = radius of loop.

Radius of loop is gotten as shown... Radius = diameter /2, but diameter = 65mm hence radius = 32.5mm = 32.5×10^-3 m = 3.25×10^-2m

x = distance of the sensor away from center of loop = 2.10 cm = 0.021m

By substituting the parameters into the formulae, we have that

4.15 = 1.256×10^-6 × I × (3.25×10^-2)²/2{(0.021²) + (3.25×10^-2)²}^3/2

4.15 = 13.2665 × 10^-10 × I/ 2( 0.00149725)^3/2

4.15 = 1.32665 ×10^-9 × I / 2( 0.000058)

4.15 × 2( 0.000058) = 1.32665 ×10^-9 × I

I = 4.15 × 2( 0.000058)/ 1.32665 ×10^-9

I = 4.80×10^-4 / 1.32665 ×10^-9

I = 3.61×10^5 A

What should the next lette be? A Z E B I Y O
myrzilka [38]

The letter C, because the pattern is this (I think):

Every two letters it states the vowels (a,e,i,o,u)

Then in between every two letters there starts a pattern of, saying the alphabet in order and saying the alphabet backwards.


In other words they merged these two lines:

A, B, C, D, E...

+

Z, Y, X, W, V...

=

A, Z, B, Y, C, X...etc.

then by adding this pattern of vowels you get:

A, Z, E, B, I, Y, O, (C), (U), (X)...

Answer:

x=22

Step-by-step explanation:

the triangle in which x is in is an equilateral triangle.

44 is an exterior angle to that triangle.

an exterior angle is always equal to tbe sum of the opposite 2 interior angles.

because that triangle is equilateral

x =44 ÷ 2

x=22
