Find the approximate value of the circumference of a circle with the given radius. Use = 3.14. Round your answer to the nearest hundredth.5.1 cm

how do you now what to mutliply by like 5.1 x 5.1 the multiply by 3.14

Answers

Answer 1

Answer: In solving for the value of the circumference of the circle we will just the formula c = πr². From that we will substitute the value c = (3.14)(5.1)², which is equal to c = 3.14 (26.01), which will be then c = 81.6714. In presenting the answer to nearest hundredth it would be 81.67 cm

A triangles three angles always sum up to 180 degrees. We must find angle B.

We already have angle A and C, so it's quite simple.

Angle A is 28*, and angle C is 36*

We add these two together

28 + 36 = 64

Now we subtract

180 - 64 = 116

Angle B = 116*

Use the distributive property to expand this equation please2/3 (18x + 6z)

Answers

Answer:

12x + 4z

Step-by-step explanation:

Given: 2/3 (18x + 6z)

Multiply the fraction 2/3 into each term

( $(2)/(3)$ )*18x + ( $(2)/(3)$ )*6z

$(36)/(3)$ x + $(12)/(3)$ z

12x + 4z

Graph the function f(x) = x4 − 7x3 + 12x2 + 4x − 12 using graphing technology and identify for which values of x the graph is increasing.

Answers

we have

$f(x) = x^(4) - 7x^(3) + 12x^(2) + 4x - 12$

The options of the question are

A. X:-3 to x:-2

B.x:-2 to x:-1

C. X:1 to x:2

D. X:2 to x:3

Using a graph tool

see the attached figure

The graph is increasing in the interval (-0.15,2) and the interval (3.4, ∞)

The graph is decreasing in the interval (-∞, -0.15) and the interval (2,3.4)

therefore

the interval (1,2) is included in the interval (-0.15,2)

the answer is the option

C. X:1 to x:2

Answer:

Value of x is increasing between $-0.147<x<2$ and $x>3.397$

Step-by-step explanation:

Given : Function $f(x)=x^4-7x^3+12x^2+4x-12$

To find : For which values of x the graph is increasing.

Solution :

We have plot the graph of the given function $f(x)=x^4-7x^3+12x^2+4x-12$

The graph is attached below.

We see that the value of x is increasing from the interval

A- $(-0.147,-12.306)$ to $(2,4)$

B- $(3.397)$ to $(\infty)$

Which means x value is increasing between

$-0.147<x<2$ and $x>3.397$
