Well the principals patterns are that the equations are quadratic equations, and the graphs are parables and that the equations and the graphs are related.

Answer:

A. S = 65 + 10x

B. 3.3 hours

Step-by-step explanation:

A. S=f(T)

65 = f(0)

85 = f(2)

S₂ - S₁

85 - 65 = 20

T₂ - T₁

2   -   0  = 2

20 / 2 = 10

For every hour you study, you will score an additional 10 points with a baseline of 65 points.

S = 65 + 10x where x is the amount of time (in hours) that you studied for.

B. S = 65 + 10x

Since we want a specific score of 98, we plug it in for S and solve for x.

98 = 65 + 10x

33 = 10x

3.3 = x

If we wanted a score of 98, we would need to study for 3.3 hours.

Note ; We multiplied each of the x-values with their probabilities and obtain the sum of all. This gives the expected value.

Since question is incomplete, I will try my best to complete it my way:

It is given that 2 cups of blue with 10 cups of yellow make up green.

Question asks how many cups of yellow would i need to mix with 1 cup of blue to make same shade of green.

So,

2 cup with 10 cup

We divide each by 2, to get:

2/2 = 1

10/2 = 5

This means:

1 cup with 5 cup

Or,

1 cup blue with 5 cup yellow.

So, we arrive at our answer:

with 1 cup of blue, we need to fix 5 cups of yellow to get same shade of green.

The common differences of arithmetic sequence are;

For a) -3

For b) - 20

For c) - 30

For d) - 10

What is Arithmetic sequence?

An arithmetic sequence is ordered set of numbers that have common difference between each consecutive term.

Given that;

The Arithmetic sequence are;

a) 35, 32, 29, 26 ...

b) - 3, -23, - 43, -63

c) -34, -64, -94, - 124

d) - 30, - 40, - 50, -60

Now, The common difference of an arithmetic sequence is calculated by the difference between each consecutive term.

For Arithmetic sequence a;

Common difference = 32 - 35 = -3

And, For Arithmetic sequence b;

Common difference = - 23 - (-3)

                               = - 23 + 3

                               = - 20

For Arithmetic sequence c;

Common difference = - 64 - (-34)

                               = - 64 + 34

                               = - 30

For Arithmetic sequence d;

Common difference = - 40 - (-30)

                               = - 40 + 30

                               = - 10

Thus, The common differences of arithmetic sequence are;

For a) -3

For b) - 20

For c) - 30

For d) - 10

Answer:

Step-by-step explanation:

first you need to figure out what your solving for We will set the first derivative of the function to zero and solve for x to get the critical point. If we take the second derivative or f''(x), then we can find out whether this point will be a maximum or minimum. If the second derivative is positive, it will be a minimum value.

Given,

The expression of the function is,

Required

The graph of the function.

Take x = 1 then the value of y is,

Take x = 2 then the value of y is,

Take x = 0 then the value of y is,

Take x = -1 then the value of y is,

Take x = -2 then the value of y is,

The graph of the function is,

The vertex of the graph is (-2, -1).

The x - intercept of the graph is -1 and -3.

The y - intercept of the graph is at 3.

Hence, the graph of the function is obtained.

The dimension of minimum paper size would be 18 inches by 9 inches.

Let the paper size be x inches in length and y inches in width.

The length of the printed space would be x-8 inches and width would be y-4 inches.

Print area would thus be (x-8)(y-4)=50.

From this [tex]$y=4+\frac{50}{x-8}=\frac{4 x+18}{x-8}$[/tex]

Also from the same equation on simplifying, it is x y-8 y-4 x+32=50.

Since the area of the paper of size x inches by y inches is xy, let it be denoted as A.

Thus

[tex]$A-8 y-4 x=18$[/tex] Or [tex]$A=8 y+4 x+18$[/tex]

[tex]$A=\frac{32 x+144}{x-8}+4 x+18$[/tex].

For minimum paper size [tex]$\frac{d A}{d x}$[/tex] must be =0, hence,

[tex]$\frac{d A}{d x}=\frac{32(x-8)-(32 x+144)}{(x-8)^2}+4=0$[/tex]

[tex]$\frac{-400}{(x-8)^2}+4=0$[/tex]

(x-8)² = 100

x-8 = 10

[tex]$\mathrm{x}=18$[/tex], hence [tex]$\mathrm{y}=4+\frac{50}{x-8}=9$[/tex]

Dimension of minimum paper size would be 18 inches by 9 inches.

Based on the probability of the macro-economic probabilities and the share returns, the expected share return can be found to be 10%.

The expected share return based on the economic probabilities can be found by the formula:

= (Probability of recession x Share return in recessions) + (Probability of steady state x Share return in steady state) + (Probability of boom x Share return in boom)

Solving for the expected share return gives:

= (20% x 5%) + (60% x 10%) + (20% x 15%)

Answer: Divisor

Step-by-step explanation:

The the answer to a division problem is called the quotient. The number that is doing the dividing is called the divisor. The number that gets divided up is called the dividend.

Example: If 3 boys ask to mow your yard for $24, then each boy would get $8.

24 divided by 3 is 8. (24 / 3 = 8 )

24 is the dividend (the number getting divided up)

3 is the divisor (the number that is doing the dividing)

8 is the quotient.

Answer:

P(A and B) = 0.25

Step-by-step explanation:

Since P(A) and P(B) are independents events, The probability P(A) and P(B) occurs consecutively is P(A)*P(B):

P(A and B) = P(A)*P(B)

P(A and B) = 0.512*0.488

P(A and B) = 0.25

We have the next given information:

-18.5% is the percentage of methyl alcohol

- The bottle contains 1.43 L

Now, we need to convert the percentage into a decimal.

Then 18.5% = 0.185

We need to determinate the volume in millimeters for methyl alcohol:

If 143L of solution contains 18.5% of methyl alcohol. Therefore:

The volume of methyl alcohol = 1.43 * 0.185

= 0.26455 L

Then, we need to convert Liters to milliliters:

1L ---------------------------- 1000ml

0.26455 L ------------------ x

Where x = (0.26455 L*1000ml)/1L

x =264.55ml

To solve this triangle, we cannot use either the Pythagorean Theorem or the Law of Cosines. We need more information.

Conversely, we can use SOHCAHTOA, in the sense that we can use the SOH part of this (Sine = opposite side over hypotenuse), that is, we can use angle 33 as the reference angle, and we have a right triangle here. Then, using trigonometric ratios, we can use:

We also can use the Law of Sines to solve it:

Therefore, we can solve this triangle using both Law of Sines and SOHCAHTOA. (We can select two options: c and d.)

The range of the function is determined as 1 ≤ M ≤ 6.5 kg.

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

Also we can defined a domain of a function as all the possible values that go into a function.

From the  graph the range of the function of the mass of the bucket is calculated as follows;

The minimum value of the mass of the bucket = 1

The maximum value of the mass of the bucket = 6.5 kg

The range of the function (mass, M of the bucket) = {1, 2, 3, 4, 5, 6.5 kg}

1 ≤ M ≤ 6.5 kg

Answer:

Distance = 9 ft

Explanation:

We can represent the position of the large fish with the number -13 because it is 13ft below the surface. In the same way, we can represent the position of the smaller fish with the number -4.

Then, the distance between the fish will be the absolute value of the difference between their positions. So, the expressions that are equivalent to the distance between the fish are:

| - 13 - ( - 4) | = | - 13 + 4| = 9

or

| -4 - (- 13) | = | - 4 + 13 | = 9

Therefore the distance between the fish is 9 ft
