I Got The Answer 0.007853982 Inches Sq, But It Says Its Not Correct, What Am I Doing Wrong?

Answers

Answer 1

Answer:

Area of pupil = 0.007855 square inch.

Step-by-step explanation:

Given the following data;

Diameter = 0.1 inch

To find the area of the pupil (circle);

Area of circle = π(D/2)²

Area of pupil = 3.142*(0.1/2)²

Area of pupil = 3.142*(0.05)²

Area of pupil = 3.142*0.0025

Area of pupil = 0.007855 square inch.

I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked

Answers

Answer:

35 feet

Step-by-step explanation:

We'll begin by calculating the resultant for you and your friend.

For you:

R² = 12² + 9²

R² = 144 + 81

R² = 225

Take the square root of both side

R = √225

R = 15 feet

For your friend:

R² = 16² + 12²

R² = 256 + 144

R² = 400

Take the square root of both side

R = √400

R = 20 feet

Finally, we shall determine the distance between you and your friend.

The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e

You resultant = 15 feet

Your friend's resultant = 20 feet

Distance between you and your friend = 15 + 20 = 35 feet.

Therefore, you threw the baseball 35 feet away from your friend.

Answer- Plato; It is the graph of y=2x translated 4 units downward. & It is the graph of y=2x translated 2 units to the right.​

Answers

Answer:

It is the graph of y=2x translated 4 units downward

Step-by-step explanation:

Given

[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]

Required

We have:

[tex]y = 2x[/tex]

Subtract 4 from both sides [In other words, shift downward by 4 units]

[tex]y - 4 = 2x - 4[/tex]

This implies that:

[tex]y' = y -4[/tex]

Substitute [tex]y = 2x[/tex]

[tex]y' = 2x -4[/tex]

Answer:

It is the graph of y = 2x translated 4 units downward.

It is the graph of y = 2x translated 2 units to the right.

Step-by-step explanation:

Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

Find value of x
Find value of y

Answers

Answer:

Step-by-step explanation:

use  SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

then we know the adjacent side and the angle, and want to find the Hyp, so use  CAH

Cos(60) = ( 8[tex]\sqrt{3}[/tex]  / 3 ) / Hyp       ( cos(60) = 1/2 )

Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)

Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)

Hyp = 16[tex]\sqrt{3}[/tex] / 3

x =  16[tex]\sqrt{3}[/tex] / 3

Now use SOH

Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3      ( sin(60) = [tex]\sqrt{3}[/tex]/2 )

(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp

16 * 3 / 6  = Opp

8 = Opp

y = 8

The graph of a twice differential function is shown at right. Which of the following is true?

Answers

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)

The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.

What is a differential function?

A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

Given:

The coordinate of the graph is shown in figure  (2, 0),

As we can see from the graph, the slope: f' (2) is negative (Downwards)

Again, from the graph

f(2) = 0

Thus, the curve concave upward: f'' (2) is positive (upward)

f' (2)<0

f (2)=0

0 < f'' (2)

f' (2) < 0 < f'' (2)

Therefore, f' (2) < 0 < f'' (2) is true in the given graph.
