what are the values for matrix a?

Answer:

10 percent

Step-by-step explanation:

- Before 1997, people with a minimum FBGL of 140mg/dl were diagnosed as diabetic

- After 1997, people with a minimum FBGL of 126mg/dl were diagnosed as diabetic

- What is the proportion of people who were not considered diabetic before 1997 but are now considered diabetic (after 1997)?

140 - 126 = 14

In percentage, this proportion is = 14/140 × 100

= 10%

Hence, 10% of the people who were not considered diabetic before 1997 are now or will now be considered diabetic.

Answer:45.167

Step-by-step explanation:

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)

Answer: 64 and 81

Step-by-step explanation: I used my brain. :)

The number 72 lies between the perfect squares  64 and 81 . So, the square root of 72 lies between the numbers  7 and 8 , which means the square root of 72 is  a rational  number.

Answer:

233.8 Yards

Step-by-step explanation:

Given that,

Length of a rectangular field, l = 227 yards

Breadth of a rectangular field, l = 56 yards

Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,

[tex]x=\sqrt{l^2+b^2} \\\\x=\sqrt{(227)^2+(56)^2} \\\\x=233.8\ \text{Yards}[/tex]

So, the distance from one corner of the field to the opposite corner is 233.8 Yards.

Step-by-step explanation:

Given [tex]g'(x) = g^{-2}, x> 0\ g(1) = 0 \ and \ g(2) = 0[/tex]

To get g(x), we will have to integrate g'(x)

[tex]g(x) = \int\limits {x^{-2}} \, dx\\ g(x) = \frac{x^{-2+1}}{-2+1} + C\\ g(x) = -x^{-1} + C\\g(x) = -x^{-1} + C\\[/tex]

If g(1) = 0, this means at x = 1, g(x) = 0

0 = -1⁻¹ + C

C= 1

Substitute C = 1 into the function

g(x) = -x⁻¹ + 1

If g(2) = 0, this means at x = 2, g(x) = 0

0 = -2⁻¹ + C

C= 2⁻¹

C =  1/2

Substitute C = 2 into the function

g(x) = -x⁻¹ + 1/2

81[tex]x^{4}[/tex] + 216x³ + 216x² +96x + 16

Step-by-step explanation:

With coefficients from Pascal's triangle for n = 4

1  4  6  4  1

with decreasing powers of 3x from [tex](3x)^{4}[/tex] to [tex](3x)^{0\\}[/tex]

and increasing powers of 2 from [tex](2)^{0}[/tex] to [tex](2)^{4}[/tex]

Thus

[tex](3x+2)^{4}[/tex]

= 1[tex](3x)^{4}[/tex][tex](2)^{0}[/tex] + 4[tex](3x)^{3}[/tex][tex](2)^{1}[/tex] + 6(3x)²(2)² + 4[tex](3x)^{1}[/tex][tex](2)^{3}[/tex] + 1[tex](3x)^{0}[/tex][tex](2)^{4}[/tex]

=1.[tex]81x^{4}[/tex].1 + 4.27x³.2 + 6.9x².4 + 4.3x.8 + 1.1.16

= 81[tex]x^{4}[/tex] + 216x³ + 216x²+ 96x + 16

Answer:

x = 46

Step-by-step explanation:

64-18=46

Answer:

x=46

Step-by-step explanation:

Subract the 18 from both sides, canceling the 18 from the 'x + 18' and leaving you to subtract 18 from 64, resulting in 46.

Answer:

The largest possible area is 10,000 square feet

Step-by-step explanation:

Since she has 400 ft of fencing material, this means that the perimeter of the pen will be 400 ft

Mathematically, the perimeter of a rectangle is is;

2(l + b) = 400

Thus, l + b = 400/2

l + b =200

This means the length and width pen add up to 200

Mathematically, the maximum area can be obtained if the side of the length and the width are equal

So we will have to share the 200 into 2 , that makes 100 for each

The largest possible area is thus;

100 ft * 100 ft = 10,000 square feet

The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

The equation is given as:

[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]

Take the LCM

[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]

This gives

[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]

Cross multiply

[tex]40(2x + 18) =x(x + 18)[/tex]

Expand

[tex]80x + 720 =x^2 + 18x[/tex]

Collect like terms

[tex]x^2 + 18x - 80x -720 = 0[/tex]

[tex]x^2 - 62x -720 = 0[/tex]

Using a graphing calculator, we have:

[tex]x = 72\ or\ x =-10[/tex]

The value of x cannot be negative, because of the context.

So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10
