A circle with a radius of 15.4 meters. Which statements are true about the circle shown? Check all that apply. The diameter of t

he circle is 30.8 m. The circumference in terms of Pi is 30.8Pi m. The circumference of the circle can be found using 2(Pi)(15.4) The approximate circumference of the circle rounded to the nearest tenth is 96.7 m. A little more than 6 diameters could be wrapped around the circle.

Step-by-step explanation:

the diameter of a circle is simply 2×radius.

2×15.4 = 30.8 m

the diameter is 30.8 m is true.

the circumference of a circle is

2×pi×radius

2×pi×15.4 = 30.8×pi m

the circumference is 30.8pi m is true.

therefore, the circumference can be found using

2(pi)(15.4)

is true.

now, doing the pi multiplication :

30.8 × pi = 96.76105373... m

the approximate circumference is 96.7 m is true.

6 diameters would be

30.8×6 = 184.8 m

that is much longer than the circumference.

so, more than 6 diameters could be wrapped around the circle is false, if we understand it that this is supposed to wrap the circle once without any overhanging remainder.

Answer:

dy/dx = 2/x

Step-by-step explanation:

y = In x^2

Let u = x^2

du/dx = 2x

y = In u

dy/du = 1/u

dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x

For algebraic expression 2x4
Fynjy0 [20]

Answer:

See explanations below

Step-by-step explanation:

Given the algebraic expression 2x4– 5x3 + 4x. + 7,

a) The degree is the highest power of x in the equation, from the equation we can see that the highest power of x is 4. HEnce the degree of the equation is 4

b) The terms we have are 2x^4, -5x^3, 4x and 7. In counting, we can see that we only have 4 terms in the equation hence the number of terms is 4

c) The constant term si the term without the variable x. From the equation the only term without variable x is 7. Hence the constant term is 7

d) The number attached t x is known as its coefficient. The number besides x is 4 frim the equation. Hence the coefficient of x is 4.

e) The numerical coefficient of -5x^3 is -5 since the constant value attached to x^3 is -5
