Answer:

Acceleration due to gravity is a constant

Step-by-step explanation:

gravity is a force pulling an object to the center of the earth this force also never changes

Acceleration due to gravity is a constant for the earth at every place.

Acceleration of any object is defined as the variation in the speed of the object with the variation of time. Acceleration is a vector term and to define it we require both the magnitude and the direction. The unit of acceleration can be m / sec², miles / sec², etc.

Gravity is a force that pulls an object toward the center of the earth, and this force never changes, hence acceleration due to gravity is a constant for the earth in all places.

Therefore, acceleration due to gravity is a constant for the earth at every place.

Answer:

The slope is 3

Step-by-step explanation:

We can find the slope by using

m = (y2-y1)/(x2-x1)

   = (11 -2)/(6-3)

   = 9/3

    = 3

Answer:

y = 3x – 7

Step-by-step explanation:

[tex]\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }[/tex]

[tex]\frac{11}{6} -\frac{2}{3} =[/tex]

[tex]\frac{9}{3} =[/tex]

The y-intercept of the slope is -7 if you graph it. So from the equation: y = mx + b, we get y = 3x - 7. (m is slope, b is y-intercept)

Answer:

1)The markup/percent Increase for the shoe is 136.709%

2)Amount of tax on the Kyrie 5 is $4.4

3)The new price of the shoe before taxes is $35.75

Step-by-step explanation:

1) Cost price of Kyrie 5 = $55

Selling price =  $130.19.

Difference = 130.19-55=75.19

So, Percentage increase =[tex]\frac{Change}{CP} \times 100[/tex]

Percentage increase =[tex]\frac{75.19}{55} \times 100 =136.709\%[/tex]

2)The state tax is 8%

So, Amount of tax on the Kyrie 5. = [tex]8\% \times 55[/tex]

                                                        =[tex]\frac{8}{100} \times 55[/tex]

                                                        = 4.4

So, You will pay $4.4 in taxes on the Kyrie 5.

3)You just found a coupon for 35% off!

New price of the shoe before taxes =[tex]55-35\%(55)[/tex]

                                                            =35.75

So,the new price of the shoe before taxes is $35.75

Answer:

C.[tex]f(n) = 3(2)^n[/tex] ; 48 strands of bacteria

Step-by-step explanation:

Fred placed 3 strands of bacteria in a petri dish.

The bacteria strands double every hour.

Formula : y = ab^x

Where a is the initial value

b = growth rate

x = hours

So, A formula to represent how many bacteria strands are present at the nth hour : [tex]f(n)=3(2)^n[/tex]

Now we are supposed to find how many strands of bacteria are present at 4 hours.

Substitute the value in the formula :

[tex]f(4)=3(2)^{4}[/tex]

f(4)=48

Hence 48 strands of bacteria are present at 4 hours.

Answer:

f(n) = 3(2)n; 48 strands of bacteria

Step-by-step explanation:

Answer:

6. He had Rs728.

7. There are 1875 pupils in the school.

Step-by-step explanation:

6.

He started with x amount of money.

He spent 1/4 of x. x - (1/4)x = (4/4)x - (1/4)x = (3/4)x

After buying the lottery tickets, he had (3/4)x left.

Then he spent 2/7 of the remainder on scratch cards.

He spent 2/7 of (3/4)x on scratch cards. Since he spent

2/7 of the reminder on scratch cards, he has 5/7 of the reminder left.

5/7 * (3/4)x = (15/28)x

He has (15/28)x left. He has Rs390 left.

(15/28)x = 390

15x = 390 * 28

15x = 10920

x = 728

Answer: He had Rs728.

7.

8/15 of the pupils are girls.

1 - 8/15 = 15/15 - 8/15 = 7/15

7/15 of the pupils are boys.

Let x = total number of pupils in the school

(8/15)x = (7/15)x + 125

Multiply both sides by 15.

8x = 7x + 1875

x = 1875

Answer: There are 1875 pupils in the school.

For these given four sets of data, Set: 4 has the largest standard deviation.

"Standard deviation is a measure of the amount of variation or dispersion of a set of values.

A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range."

Set: 1 {10, 19, 38, 50, 513}

Number of terms = 5

Mean = (10 + 19 + 38 + 50 + 513)/5 = 630/5 = 126

Standard deviation

Set: 3 {9, 38, 50, 50, 513}

Number of terms = 5

Mean = (9 + 38 + 50 + 50 + 513)/5 = 650/5 = 130

Standard deviation

= [√{(9 - 130)² + (38 - 130)² + (50 - 130)² + (50 - 130)² + (513 - 130)²}/5]

=  [√(14641 + 8464 + 6400 + 6400 + 146689)/5]

= 191.1

Set: 4 {5, 28, 28, 28,513}

Number of terms = 5

Mean = (5 + 28 + 28 + 28 + 513)/5 = 602/5 = 120.4

Standard deviation

= [√{(5 - 120.4)² + (28 - 120.4)² + (28 - 120.4)² + (28 - 120.4)² + (513 - 120.4)²}/5]

Answer:

The smallest whole number that can be the value of the expression is 2

Step-by-step explanation:

Given that the letters represent different digits, to get the smallest whole number value for the expression we have;

[tex]\dfrac{K \times A \times N \times G \times A \times R \times O \times O}{G \times A \times M \times E}[/tex]

The letters G and A cancel out from the numerator and the denominator to give;

[tex]\dfrac{K \times A \times N \times R \times O \times O}{M \times E}[/tex]

Therefore, the smallest whole number can be from 2 and above as the product of six digits is more than one times the product of two digits

If we put

K = 2, A = 3, N = 4, R = 6, O = 1, M = 9, and E = 8, we have;

[tex]\dfrac{2 \times 3 \times 4 \times 6 \times 1 \times 1}{9 \times 8} = \dfrac{144}{72} =2[/tex]

Therefore, the smallest whole number that can be the value of the expression = 2.

Step-by-step explanation:

ok so this is just a substitution problem.

we need to get the variable (x) by itself on one side.

4x+8=16. so, lets remove 8 from the left side, and whatever we do to one side also has to happen to the other.

4x+8=16

    -8  -8

4x=8. So now, we want to get 4 separate from x, and the only thing we can do is divide.

Answer:

a) - Compressing the P(new) function by a scale of 0.5 about the y axis.

- Moving the P(new) function down by 104 units.

b) The two simplified functions for P(original)

-0.08x² + 10.8x – 200.

-0.16x² + 21.6x – 504.

Step-by-step explanation:

Complete Question

An electronics manufacturer recently created a new version of a popular device. It also created this function to represent the profit, P(x), in tens of thousands of dollars, that the company will earn based on manufacturing x thousand devices: P(x) = -0.16x² + 21.6x – 400.

a. The profit function for the first version of the device was very similar to the profit function for the new version. As a matter of fact, the profit function for the first version is a transformation of the profit function for the new version. For the value x = 40, the original profit function is half the size of the new profit function. Write two function transformations in terms of P(x) that could represent the original profit function.

b. Write the two possible functions from part a in simplified form.

Solution

The equation for the new profit function is

P(x) = -0.16x² + 21.6x – 400

At x = 40, the original profit function is half the size of the new profit function

First, we find the value of the new profit function at x = 40

P(x) = -0.16(40)² + 21.6(40) – 400 = 208

Half of 208 = 0.5 × 208 = 104

P(original at x = 40) = P(new at x = 40) ÷ 2

Since we are told that P(original) is a simple transformation of the P(new)

P(original) = P(new)/2 = (-0.16x² + 21.6x – 400)/2 = -0.08x² + 10.8x – 200 ... (eqn 1)

Or, P(original) = 104

-0.16x² + 21.6x – 400 = 104

P(original) = -0.16x² + 21.6x – 400 - 104 = -0.16x² + 21.6x – 504.

So, the two functions that are simple transformations of P(new) to get P(original) are

-0.08x² + 10.8x – 200

Obtained by compressing the P(new) function by a scale of 0.5 about the y axis.

And

-0.16x² + 21.6x – 504.

Obtained by moving the P(new) function down by 104 units.
