Answer:

if 4 5 is 4.5 then the answer would be 5.2

Step-by-step explanation:

9.7-4.5

Answer:49%

Step-by-step explanation:

a) Picking a yellow marble and picking a red marble from the bag are mutually exclusive events because a marble cannot be both yellow and red at the same time. Therefore, if one event occurs, the other cannot occur simultaneously.

b) It is possible to work out P(yellow or red) because the events of picking a yellow marble and picking a red marble are disjoint or mutually exclusive.

To find P(yellow or red), we can add the probabilities of picking a yellow marble and picking a red marble:

P(yellow or red) = P(yellow) + P(red)

P(yellow or red) = 34% + 15%

P(yellow or red) = 49%

Therefore, the probability of picking a yellow or a red marble from the bag is 49%.

The position vector of a particle is given by r(t)=0.1ti^+0.3t2j^+11k^ in meters and t is in seconds. To find the particle's acceleration at t = 2 s, we can find its velocity vector by dividing it by time. The acceleration is zero, and the particle's velocity makes an angle of 84.3° with the +x-axis at t = 2 s. Therefore, the particle's acceleration at t=2s is 0 m/s^2.

The position vector of a particle is given by r(t)=0.1ti^+0.3t2j^​+11k^ in units of meters and t is in units of seconds. Let's find the acceleration of the particle at t = 2 s.First, find the first derivative of the position vector r(t) to get the velocity vector

v(t).r(t) = 0.1ti^+0.3t2j^​+11k^ ...........................(1)

Differentiating equation (1) with respect to time, we get the velocity vector

v(t).v(t) = dr(t) / dt = 0.1i^ + 0.6tj^​...........................(2)

Differentiating equation (2) with respect to time, we get the acceleration vector

a(t).a(t) = dv(t) / dt = 0j^​...........................(3)

Substituting t = 2 s in equation (3), we geta(2) = 0j^​= 0 m/s^2

The acceleration of the particle at t = 2 s is zero. 11. For the particle above, what angle does the particle's velocity make with the +x-axis at t=2 s?Velocity vector at time t is given by,v(t) = 0.1i^ + 0.6tj^Substituting t = 2 s, we get,v(2) = 0.1i^ + 1.2j^The angle θ made by the velocity vector with the +x-axis is given by,

θ = tan⁻¹(v_y/v_x)

where, v_y = y-component of velocity vector, and v_x = x-component of velocity vectorSubstituting the values,θ = tan⁻¹(1.2/0.1) = tan⁻¹(12) = 84.3°

The particle's velocity makes an angle of 84.3° with the +x-axis at t = 2 s. Therefore, the answer is, "The acceleration of the particle at t=2s is 0 m/s^2. The angle the particle's velocity makes with the +x-axis at t=2s is 84.3°."

Step-by-step explanation:

According to SOH CAH TOA;

cos theta = adjacent/hyp = 5/13

adj = 5

hyp = 13

Get the opposite

opp = √13²-5²

opp = √169-25

opp = √144

opp = 12

Get sin theta

sin theta = opposite/hyp

sin theta = 12/13

Hence the value of sin theta is 12/13

Answer:

x=13

Step-by-step explanation:

Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.

So, (5x-11) x (2x+20) x (11x-63) = 180.

Now, take away the parenthesis and add up all the like terms.

This should = 18x-54 = 180.

Now solve like you regularly would. Add 54 on both sides which equals,

18x=234. Now, divide 18 on both sides.

x = 13.

Answer:

s = 6 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = \(\frac{s^2\sqrt{3} }{4}\) ( s is the length of side )

Here A = 9\(\sqrt{3}\) , thus

\(\frac{s^2\sqrt{3} }{4}\) = 9\(\sqrt{3}\) ( multiply both sides by 4 to clear the fraction )

s²\(\sqrt{3}\) = 36\(\sqrt{3}\) ( divide both sides by \(\sqrt{3}\) )

s² = 36 ( take the square root of both sides )

s = \(\sqrt{36}\) = 6

To determine the percentage of SKUs (Stock Keeping Units) that have line fill rates of less than 100 percent, we need more specific information about the data. Line fill rate refers to the proportion of orders or requests for a specific SKU that are filled completely from available stock.

If we have data on the line fill rates of each SKU, we can calculate the percentage by dividing the number of SKUs with line fill rates less than 100 percent by the total number of SKUs, and then multiplying by 100.For example, if we have data on 500 SKUs and 250 of them have line fill rates less than 100 percent, the percentage would be (250/500) * 100 = 50 percent.

Therefore, without specific data on the line fill rates of SKUs, it is not possible to determine the exact percentage.

Step-by-step explanation:

For f(x) = 4x^2 + 12x - 7: i) Critical value: x = -3/2, ii) Increasing interval: (-∞, -3/2), Decreasing interval: (-3/2, +∞), iii) Local minimum point: (-3/2, f(-3/2)).

For f(x) = x^3 - 9x^2 + 24x - 10: i) Critical values: x = 2, x = 4, ii) Increasing interval: (-∞, 2), (4, +∞), Decreasing interval: (2, 4), iii) Local minimum points: (2, f(2)), (4, f(4)).

To find the critical values, intervals of increasing or decreasing, and the maximum and minimum points of the given functions, we need to take the following steps:

i) Critical Values:

The critical values of a function occur where its derivative is either zero or undefined. To find the critical values, we need to differentiate the given functions.

For f(x) = 4x^2 + 12x - 7, we take the derivative:

f'(x) = 8x + 12

Setting f'(x) = 0 and solving for x:

8x + 12 = 0

8x = -12

x = -12/8

x = -3/2

For f(x) = x^3 - 9x^2 + 24x - 10, we take the derivative:

f'(x) = 3x^2 - 18x + 24

Setting f'(x) = 0 and solving for x:

3x^2 - 18x + 24 = 0

x^2 - 6x + 8 = 0

(x - 2)(x - 4) = 0

x = 2 or x = 4

ii) Intervals of Increasing or Decreasing:

To determine the intervals of increasing or decreasing, we need to analyze the sign of the derivative.

For f(x) = 4x^2 + 12x - 7:

Since f'(x) = 8x + 12, the derivative is positive for x > -3/2 and negative for x < -3/2. Therefore, the function is increasing on the interval (-∞, -3/2) and decreasing on the interval (-3/2, +∞).

For f(x) = x^3 - 9x^2 + 24x - 10:

Since f'(x) = 3x^2 - 18x + 24, we can factor the quadratic expression:

f'(x) = 3(x - 2)(x - 4)

The derivative is positive for x < 2 and x > 4, and negative for 2 < x < 4. Therefore, the function is increasing on the intervals (-∞, 2) and (4, +∞), and decreasing on the interval (2, 4).

iii) Maximum and Minimum Points:

To find the maximum and minimum points, we can use the critical values and analyze the behavior of the function.

For f(x) = 4x^2 + 12x - 7:

Since the function is increasing on the interval (-∞, -3/2) and decreasing on the interval (-3/2, +∞), the critical value x = -3/2 corresponds to a local minimum.

For f(x) = x^3 - 9x^2 + 24x - 10:

The critical values x = 2 and x = 4 correspond to potential maximum or minimum points. To determine which is which, we can analyze the behavior of the function around these points. By substituting values into the function, we can see that f(2) = 2 and f(4) = 2. Therefore, x = 2 and x = 4 correspond to local minimum points.

For f(x) = 4x^2 + 12x - 7:

i) Critical value: x = -3/2

ii) Increasing interval: (-∞, -3/2)

Decreasing interval: (-3/2, +∞)

iii) Local minimum point: (-3/2, f(-3/2))

For f(x) = x^3 - 9x^2 + 24x - 10:

i) Critical values: x = 2, x = 4

ii) Increasing interval: (-∞, 2), (4, +∞)

Decreasing interval: (2, 4)

iii) Local minimum points: (2, f(2)), (4, f(4))

Please note that the explanation provided assumes that the given functions are defined for all real numbers. If there are specific domains specified for the functions, it is important to consider them while determining the intervals and points.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The line representing the equation 7x1 + 4x2 = 28 is a boundary line that separates the feasible solutions from the infeasible solutions in a linear programming problem.

The line passes through two points, which can be determined by substituting the x1 and x2 values into the equation. By substituting the values (4,0) and (7,0) into the equation, we can see that both points satisfy the constraint.

This means that any point on the line also satisfies the constraint, and any point above or to the right of the line would be infeasible as they would not meet the requirement of the constraint.

Understanding the position and shape of the constraint lines is important in solving linear programming problems and finding the optimal solution.
