Answer:

y = 0.25x³

Step-by-step explanation:

Since y is directly proportional to x³, then y = kx³, where k is a constant.

When x = 10, y = 250,

   250 = k(10)³

1000k = 250

    ∴ k = 0.25

∴ y = 0.25x³

Answer:

t=1.33333 seconds

Step-by-step explanation:

1. We are give the the position function, s(t). We must differentiate s(t) twice in order to find the acceleration function, a(t).

s(t) = t⁶-2t⁵

Taking the power rule to differentiate s(t), we find the velocity function, v(t).

v(t) = d/dt (t⁶-2t⁵)

v(t) = 6t⁵-10t⁴

Differentiate v(t) using the power rule again to find the acceleration function, a(t).

a(t) = d/dt (6t⁵-10t⁴)

a(t) = 30t⁴-40t³

2. To find the other t value where acceleration is equal to zero, we must set a(t) to zero.

a(t) = 30t⁴-40t³ = 0

3. Algebraically solve for t. Factoring out 10t³ from a(t), we have:

10t³(3t-4)=0

Our solutions are t=0 and t=4/3.

The other value of t when acceleration is equal to zero is 4/3, or 1.33333 seconds.

The probabilities in this problem are given as follows:

The probabilities for each strike are given as follows:

The probabilities are independent, meaning that for each trial they are the same.

Thus the probability that your first strike was a critical hit but not your second strike is obtained as follows:

P = 0.33 x 0.67 = 0.2211 = 22%. (rounded).

Damage is caused with two consecutive critical hits, hence:

p = 0.33 x 0.33 = 0.11 = 11%.

The final probability, that your strike was not critical but your next 2 attacks were, is obtained as follows:

p = 0.67 x 0.33 x 0.33 = 0.07 = 7%.

The slope is -5/3

From the question, we have

slope, m = change in y/change in x

= (-6+1)/(8-5)

=-5/3

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Slope of a Line :

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.

where "m" represents a line's slope.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The value of x and y in the similar triangles are 10 and 12 respectively.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In other words, similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other

The triangles ABC and MPN are similar triangles.

Therefore,

∠A = ∠M

∠B = ∠P

∠C = ∠N

Hence, let's find x and y using the proportion as follows:

86.135 is the IQ score separating the bottom 25% from the top 75%.

The number between a data set's lowest and median is known as the first quartile. We would utilize a Z table to locate it.

As we are looking on the left side of distribution, value of z-score will be negative.

z-score equation for x : [tex]z = \frac{x-M}{S}[/tex]

                                       [tex]x = zS+M[/tex]

where x = value we're looking for

   = 99.2

S = Standard deviation

  = 19.5

z = z-score

To *increase* a quantity in given ratio consider new quantity and old quantity.

Formula: New quantity:old quantity=given ratio solution: let us take the new quantity as x, old quantity as 24(given) and given ratio=2:3(given)

-> x:24=2:3

-> x/24=2/3

-> Multiply with 24 on both sides to get x

What is digit?
A positional numeral system uses a single symbol, such as "2," or a combination of symbols, such as "25," to represent numbers. This single symbol is known as a numerical digit. The word "digit" derives from the fact that ten fingers (Latin: digiti) on each hand correspond to the ten numeral symbols used in the base-10 system, or decimal digits (Old Latin: decem, meaning "ten"). The absolute value of the base determines how many different digits are necessary for a given numeral system with just an integer base. For instance, the binary system (base 2) only needs two digits, whereas the decimal system (base 10) necessitates ten digits (0 through 9). (0 and 1).

The digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

There are nine options because the first digit cannot be 0. (assuming 1 can be the first digit as well as all others)

A equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x

We know that the formula for the slope-point form of equation of line:

(y - y1) = m(x - x1)

Let (x1, y1) = (-16, 7)

and slope m = -7/16

Using above formula,

(y - 7) = (-7/16)(x - (-16))

y - 7 = (-7/16)(x + 16)

y = -7/16x - 7 + 7

y = (-7/16)x

This equation is slope-intercept form (y = mx + c) with slope -7/16 and y-intercept 0.

Answer:

Step-by-step explanation:

Find the equation of p(x) using table.

We see it is a proportional relationship, therefore:

Conveyor belt2: p(x) = 62.8x

As we see 157.1 > 62.8 which means conveyor 1 belt is faster.

Answer:

The conveyor belt 1 is faster.

Step-by-step explanation:

Speed of conveyor belt 1,

→ m(x) = 157.1x

Now the speed of conveyor belt 2,

→ p(x) = x

→ p(125.6) = 2x || p(188.4) = 3x

→ x = 125.6/2 || x = 188.4/3

→ [ p(x) = 62.8 ] || [ p(x) = 62.8 ]

Then the fastest conveyor is,

→ m(x) = 157.1x > p(x) = 62.8

→ 157.1x > 62.8

→ Conveyor 1 > Conveyor 2

Hence, the conveyor belt 1 is faster.

From the question, we have the table of values that can be used in our computation:

In the table, we have the following rows

Plants and Number of tomatoes

The mean of the number of plants is calculated as

Mean plant = Total number of tomatoes/Total number of plants

For the four plants, we have

Total number of tomatoes = 31 + 25 + 6 + 28 =  90

Total number of plants = 4

Substitute the known values in the above equation So, we have the following equation

Mean plant = 90/4

Mean plant = 22.5

For the three plants, we have

Total number of tomatoes = 31 + 25 + 28 =  84

Total number of plants = 3

Substitute the known values in the above equation So, we have the following equation

Mean plant = 84/3

Domain is the "allowable x-values/inputs"

Range is the "possible y-values/outputs when the x-values in the domain are inputted".

From the graph, notice how each end of it extends infinitely to the left and to the right. This means that the domain is infinite and there are no restrictions. Writing it in interval location would look like this:

What is Probability?

From the question, it is given that the,

Number of Red marbles = 8

Number of Yellow marbles = 9

Number of Green marbles = 7

So, the total number of marbles = 8 + 9 + 7 = 24

Let [tex]x[/tex] be the additional number of red marbles added to the bag.

The total number of red marbles after the addition of [tex]x[/tex] red marbles into the bag = [tex]8+x[/tex]

The total number of all marbles after the addition of [tex]x[/tex] red marbles into the bag = [tex]24+x[/tex]

The probability of randomly drawing a red marble is given as equal to [tex]\frac{3}{5}[/tex]

We know that, the probability of randomly drawing a red marble is equal to the ratio of the total number of red marbles to the total number of all marbles.

---> P(R) = n(R)/n(T)

Substituting the given values, we get

3/5 = 8+x / 24+x
---> 5(8+x) = 3(24+x)
---> 40 + 5x = 72+3x

Solving, we get

5x - 3x = 72 - 40
---> 2x = 32
---> x = 16

Therefore, the additional number of red marbles to be added to obtain the required probability is equal to 16.
