Answer:

We have the equation:

[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]

Where:

W₀ is the initial area of the wound, and t is the time in days.

Now, if we initially have a wound of 25 mm^2, then:

W₀ = 25mm^2

And we can replace it in the equation, then we get:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]

We want to know the size of this wound after:

a) 1 day.

We know that t represents time in days, so here we just need to replace t by one, then:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]

b) 1 week

Again, t represents the time in days, so we need to write this in days.

We know that:

1 week = 7 days.

then t = 7

The size of the wound after 7 days is:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]

Answer:

282.6

Step-by-step explanation:

v=pi r^2 h =3.14x9x10

since diameter is 0.5 feet then it is equal to 6 inch so diveided by 2 give 3 as radius and square 3 give 9 so 3.14x9x10 = 282.74 which 282.6 is the closees answer  

Answer:

x = 13

Step-by-step explanation:

using the Pythagorean theorem

x² = 85² - 84²

x² = 7225 - 7056 = 169

x = 13

Answer:

x = √(85²-84²)

x = √(7225-7056)

x = √169

x = 13

Answer:

1/ 6

7/ 12

Step-by-step explanation:

Answer:

7a) 1/7

7b) 7/12

Step-by-step explanation:

For 7a) you know that the denominator of 5/6 is equal to 6 so that means you should make 1 have a denominator of 6. To do that, you have to multiply the denominator and the numerator by 6 to get 6/6-5/6=?. With this, you could easily solve the two fractions because they have equal denominators. You subtract the numerator and keep the denominator. 6-5=1 so the answer is 1/6.

For 7b) I would first convert 1 3/12 into an improper fraction. To do that, you have to multiply the whole number by the denominator then add the numerator. It will look like this 12x1+3/12 which is equal to 15/12. This makes the question easier to solve. You then want to convert 2/3 to have a denominator of 12. To do that, you have to multiply 4 on the numerator and denominator. This will turn the fraction into 8/12. After you do that, you can easily subtract the fractions again. you do 15-8/12 which is equal to 7/12.

circumference=2\pi r

25.12cm

Step-by-step explanation:

hope this helps

The required circumference of the given circle is 25.12 cm as shown figure.

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have been given data as follows:

The radius of the circle (r) = 4 cm

Circumference of the circle = 2πr

Substitute the values in the above formula and we get

Circumference of the circle = 2π(4)

Circumference of the circle = 3.14(8) = 25.12 cm

The required circumference of the given circle is 25.12 cm.
