When using the exponential DECAY formula, what would be the value of r?

Answers

Answer:

The value of r will be 0.043

Step-by-step explanation:

Firstly, we need to write the exponential decay formula

the general form of the formula is;

A = P(1-r)^t

where A is the price after a certain year t

P is the initial value

r is the decay rate

t is the time

From the question, we have that;

r = 4.3%

4.3% in decimal will be 4.3/100 = 0.043

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 46°, what does ZADC measure?

Answers

Step-by-step explanation:

given: B is the centered poin of the circle

points A,C,D lies on its circumference

measure angle ABC is 46⁰

<ADC is inscribed in the circle

<ABC is the central angle

to find: what is the measure of angle ADC?

solution:

inscribed angle therom states that an inscribe angle is half of a central angle that subtends the same arc

hence, <ADC = 1/2 × <ABC

<ADC= 1/2 × 46⁰

<ADC=1/2 ×46⁰

<ADC= 23⁰

Please please please help help help help me me me me me me

Answers

Answer:

x = 11

Step-by-step explanation:

Assuming that segment EG is a diameter we can solve this using the straight angle theorem ( Which states that angles on a straight line add up to equal 180. Also note that central angles and there corresponding arcs are congruent. )

We are also told that CH is a bisector.

A bisector splits an angle into TWO EQUAL parts.

mDG is split into mDC and mCG

So mDC = mCG

This meaning that because mDC = 7x + -1 , mCG also equals 7x - 1

Leading to us having enough information to use the straight line theorem ( which also works with half circles and arcs. )

So 180 = 2 ( 7x - 1 ) + 2x + 6

now we solve for x

step 1 distribute the 2

2 * 7x = 14x

2 * - 1 = -2

now we have 180 = 14x - 2+ 2x + 6

step 2 combine like terms

14x + 2x = 16x

-2 + 6 = 4

now we have 180 = 16x + 4

step 3 subtract 4 from each side

4 - 4 cancels out

180 -  4 = 176

Now we have 176 = 14x

step 4 divide each side by 14

176 / 16 = 11

14x/14 = x

we're left with x = 11

Ian recorded the time, in seconds, it took each contestant to solve the riddle. He recorded the results. 68 seconds 89 seconds 122 seconds 72 seconds 139 seconds 49seconds 115 seconds 83 seconds 97 seconds 56 seconds 142 seconds What is the third quartile of the data?

Answers

Your answer: 122

First we have to put the data in ascending order.

49, 56, 68, 72, 83, 89, 97, 115, 122, 139, 142.

I added spaces around the 89 because that’s the median/middle number, and it splits the data into upper and lower halves. The first quartile is the middle number of the bottom half (68), and the third quartile is the middle number of the top half (122)

Does that all make sense? Happy to answer questions.

If they ask for inner quartile range/IQR, that is the 3rd quartile minus the 1st quartile. 122 - 68 = 54

Answers

Answer:

You are correct that the cross section is a rectangle, because a rectangular pyramid has 4 sides connected to the top of the rectangle.

Step-by-step explanation:

We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.

What is simulation?

Simulation is the process of creating a computer model or a physical system that behaves like a real-world system or process, in order to study its behavior or performance under various conditions.

We have,

To estimate the probability that 3 or more kicks are made, we need to count the number of trials in which 3, 4, or 5 kicks were made, and divide that by the total number of trials (which is 5 in this case).

From the table,

We can see that there are three trials in which 3 kicks were made

(trials 1, 3, and 5), one trial in which 4 kicks were made (trial 4), and no trials in which all 5 kicks were made.

The total number of trials in which 3 or more kicks were made is:

= 3 + 1 + 0

= 4

To estimate the probability, we divide the number of successful trials by the total number of trials:

P(3 or more kicks made) ≈ 4/5

Therefore,

We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.

how do you find the scale factor in enlargement

Answers

Answer/Step-by-step explanation:

Scale factor is the ratio of the corresponding side lengths of two similar figures or shapes.

For an enlargement, divide the length of the new figure over the length of the original figure.

The scale factor of an enlargement should give you a whole number or mixed fraction.

For example, if the length an original figure is 2, and the length when enlarged is 6, the scale factor = 6/2 = 3

Quadrilateral ABCD is a rhombus, because all four sides are congruent and adjacent sides are not perpendicular .

Step-by-step explanation:

Given :

A quadrilateral with its coordinates as follows:

Where  A (3, 1), B (4,4), C (7,5), D (6,2).

We will measure the length of the congruent sides by applying distance formula.

Distance formula = square root (x^2 - x^1)^2 + (y^2 - y^1)^2

So,  

AB = ( insert the coordinates using the formula )

BC = ( insert the coordinates using the formula )  

CD = ( insert the coordinates using the formula )

 

DA = ( insert the coordinates using the formula )

It all equals = squareroot 10

From the above measurement and looking into the diagram we can conclude that the Quadrilateral ABCD is a rhombus.  

In rhombus the adjacent sides are not perpendicular and its diagonals are of different length.
