The numerator in the above is sum of the square of the given data.

Therefore,

Final Answer:

1. 5 (3) = 15

2. 4 (8) = 32

3. 6 (3/2) = 9

4. 12 ( ) = ?

Thus, the point which represent square root of 28 should lie between 5 and 6 which is point B.

Thus, option (B) is correct.

1) Let's do it in parts.

a) We can find the x-intercepts by using the factor zero property from each factor. Like this:

The best way to find the y-intercept with this factored form is by plugging into that equation x=0

b) Expanding those factors by distributing them (FOIL) we can find this:

So now, let's find the x-coordinate of the vertex V(h,k):

c) The coordinates of the vertex can be found by plugging the x-coordinate into the quadratic function. This way:

d) Finally, we can plot that function by setting a table:

So plotting these points (-2,6),(-1,6), (0,4), (1,0),(2,-6) and opening down the parabola for a is -1 we can plot this:

To compute the width of the wing, we can use the next proportion

the mean score of the test for sample of 39 students is 76.92.

The data is given as:

Number of students       Score of each student       Total score

            07                                       90                              630

             17                                       80                             1360

             11                                        70                               770

            04                                       60                              240

The total number of students = 7 + 17 + 11 + 4

n = 39

Total scores = 630 + 1360 + 770 + 240

T = 3000

Mean score = T / n

M = 3000 / 39

M = 1000 / 13

M = 76.92

Therefore, the mean score of the test for sample of 39 students is 76.92.

The population of bacteria in the culture after 11 hours is 581 using the exponential decay formula.

The total number of people living in a particular area, such as a city or town, region, country, continent, or the entire world, is typically referred to as the population. Governments frequently conduct censuses to estimate the number of residents living within their jurisdiction. A census is a process for gathering, analyzing, compiling, and releasing statistics regarding a population.

A culture of bacteria has an initial population of 220 bacteria, which doubles every eight hours, according to the information provided.

By applying the formula,

P(t)=P₀.[tex]2^{t/d}[/tex]

P(t) is the population at the end of t hours.

P0 is the starting populace.

d is the doubling time, while t is the time in hours.

After 11 hours, we are asked to determine the bacteria population.

First, we will enter the following values in the doubling life formula as substitutes:

P(t)=220([tex]2^{t/8}[/tex])

Now we will substitute t=11 in our formula to find the population of bacteria after 11 hours as follows:

P(11)=220([tex]2^{17/8}[/tex])

P(11)=220([tex]2^{1.4}[/tex])

P(11)=220(2.639015822)

P(11)=580.5834807≈581

P(11)=581

Consequently, after 11 hours, there will be 581 bacteria.

Answer

Option A is correct.

P(x, y) = (-3.5, 2.3)

Explanation

Mathematically, if a point P(x, y) divides the coordinates R(x₁, y₁) and Q(x₂, y₂) internally in the ratio m:n then point P(x, y) is given as

x = [(mx₂ + nx₁)/(m + n)]

y = [(my₂ + ny₁)/(m + n)]

For this question,

R(x₁, y₁) and Q(x₂, y₂) = R (4, -1) and Q (-5, 3)

m:n = 5:1 (5/6 of a distance divides the two parts of the distance into 5/6 and 1/6, hence, the ratio is 5:1)

x₂ = -5

x₁ = 4

y₂ = 3

y₁ = -1

m = 5

n = 1

x = [(mx₂ + nx₁)/(m + n)]

x = [(5×-5 + 1×4)/(5 + 1)]

x = [(-25 + 4)/(5 + 1)]

x = (-21/6)

x = -3.5

y = [(my₂ + ny₁)/(m + n)]

y = [(5×3 + 1×-1)/(5 + 1)]

y = [(15 - 1)/(5 + 1)]

y = (14/6)

y = 2.3

P(x, y) = (-3.5, 2.3)

let the number of quarters = x , and the number of nickels = y

quarter = $0.25 and nickel = $0.05

So, x + y = 58

x = 58 - y

and 0.25 x + 0.05 y = 7.5

so,

0.25 (58 - y) + 0.05 = 7.5

14.5 - 0.25 y + 0.05 y = 7.5

-0.2 y = -7

y = -7/-0.2 = 35

x = 58 - 35 = 23

So, the number of quarters = 23 and the number of nickels = 35

We are given that

Cost of dress per meter = $R

Total cost of dress = $ 3R

Cost of Acessories = $50

We want to find:

Part A

The total amount of money Gifty will need to spend on the dress in terms of R

To find the total amount, we just add up

Let T denotes the total amount of money

Thus, the total amount is $ (3R + 50)

Part B

If Gifty has $4000 to spend on her dress including accessories, what is the maximum value of R?​

We only need to equate T to 4000 and solve for R

Thus, the maximum value of R is $1316.67

We know that if l and m are parallel there might be some angles that are equal to others:

Alternate interior angles

The angles closed by a blue circle are alternate interior angles, then they should be equal if l||m.

Vertcial angles

The angles closed by an orange circle are vertical angles, because they are opposite to each other on two crossed lines.

Now, we know two angles of the triangle of the middle:

We know that the addition of all the inner angles of a triangle is 180º. This is:

50º + 55º + xº = 180º

↓

105º + xº = 180º

Now, we can find x:

105º + xº = 180º

↓

xº = 180º - 105º

xº = 75º
