Answer:

  B. The graph of K has a greater y-intercept

  D. The graph of J has a greater slope.

Step-by-step explanation:

Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.

The y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.

We see from the equation for function K that the constant is 8. This is the value of y when x=0.

Function K has the greater y-intercept (8 vs. 2).

The slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.

The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.

Function J has the greater slope (5 vs. 3).

Answer:

190 cm²

Step-by-step explanation:

     Area of one regular hexagon is given. Multiply 23 *2 and it will give the area of two regular hexagons.

There are 6 rectangles. Find the area of one rectangle and multiply it by 6.

 Area of regular hexagon = 23 cm²

Area of rectangle = length * width

                             = 8 * 3

                             = 24 cm²

      Area of the regular hexagon prism = 2* area of regular hexagon + 6*area of rectangle.

                                                                 = 2*23 + 6*24

                                                                 = 46 + 144

                                                                 = 190 cm²

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.

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.

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.

Answer:

a = 108°

b = 72°

c = 48°

d = 48°

Step-by-step explanation:

• ∠a and the 72° angle are on a straight line. Therefore they add up to 180°:

∠a + 72° = 180°

⇒ ∠a = 180 - 72°

⇒ ∠a = 108°

• ∠b and the 72° angle are corresponding angles (the angles make an F-shape). Therefore, they are equal:

∠b = 72°

• ∠d and the 48° angle are alternate angles (the angles make a z-shape). Therefore they are equal:

∠d = 48°

• ∠c and ∠d are vertically opposite angles. Therefore, they are equal:

∠c = ∠d

⇒ ∠c = 48°

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

When x = 10, y = 250,

Considering a discrete distribution modeling the situation, it is found that:

a) The expected value of each $1 bet in roulette is of: -$0.988.

b) The interpretation is given as follows: Over time, you should expect to lose about 999 cents for every dollar you bet.

The expected value of a discrete distribution is calculated as the sum of each outcome multiplied by it's respective probability.

The total number of outcomes for the three-number bet is of:

10 x 10 x 10 = 1000.

As three numbers are taken, and for each number, there are 10 possible outcomes.

Hence the probability of winning is of:

p = 1/1000.

As there is only one correct sequence.

The probability of losing is of:

p = 1 - 1/1000 = 999/1000.

Considering a payout of $11 for a $1 bet, the distribution of earnings is presented as follows:

Hence the expected value of a $1 bet is calculated as follows:

E(X) = 11/1000 - 999/1000 = -$0.988.

Which means that you are expected to lose approximately 99 cents for every dollar that you bet.

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%.
