The angular velocity of the ladybug is the same as the angular velocity of

the record.

Correct responses (approximate values):

a)  3.875 rad/s

b) 31 cm/s

c) 527 cm

The rate at which the record is spinning = 37 rpm

Location of the ladybug on the record = 8 cm from the center

a) The angular velocity of the ladybug is given as follows;

1 revolution = 2·π radians

1 minute = 60 seconds

Therefore;

\(Angular \ velocity, \ \omega = \dfrac{37 \times 2 \cdot \pi}{60 \, s} \approx \mathbf{ 3.875}\)

To test whether the sample data contradicts the manufacturer's claim regarding the average muzzle velocity of the new gunpowder, we can conduct a hypothesis test. The claim states that the average velocity is not less than 3000 feet per second. By performing the appropriate statistical analysis with the given sample data and significance level of 0.025, we can determine if there is sufficient evidence to reject the manufacturer's claim.

To conduct the hypothesis test, we will set up the null and alternative hypotheses as follows:

Null Hypothesis (H₀): The average muzzle velocity of the new gunpowder is not less than 3000 feet per second.

Alternative Hypothesis (H₁): The average muzzle velocity of the new gunpowder is less than 3000 feet per second.

Next, we will perform a one-sample t-test, assuming that muzzle velocities are approximately normally distributed. With the given sample data, we can calculate the sample mean and sample standard deviation. Using these values, along with the sample size and the significance level of 0.025, we can calculate the t-statistic.

Comparing the t-statistic to the critical value from the t-distribution with the appropriate degrees of freedom, we can determine if the sample data provide sufficient evidence to reject the null hypothesis. If the t-statistic falls in the rejection region, we can conclude that the sample data contradicts the manufacturer's claim at the 0.025 level of significance.

Thomas can pack the items into a maximum of 20 bags, with each bag containing 24 items after calculated with greatest common divisor.

To find the maximum number of bags Thomas can pack, we need to find the greatest common divisor (GCD) of 120, 168, and 192. The GCD will represent the maximum number of items that can be packed into each bag.

To find the GCD, we can use the Euclidean algorithm. First, we find the GCD of 120 and 168:

168 = 1 * 120 + 48

120 = 2 * 48 + 24

48 = 2 * 24 + 0

Therefore, the GCD of 120 and 168 is 24.

Next, we find the GCD of 24 and 192:192 = 8 * 24 + 0

Therefore, the GCD of 120, 168, and 192 is 24.

So, Thomas can pack 24 items into each bag. To find the maximum number of bags he can get, we divide the total number of items by 24:

Total number of items = 120 + 168 + 192 = 480

Number of bags = 480 / 24 = 20

Therefore, Thomas can get a maximum of 20 bags.

Find attached the diagram

Given:

AC = 13cm

AE = 19cm

CF = DE = 7cm

AD = AE - DE

AD =  19-7 = 12cm

GF = 9cm, EH = 15cm

GH = 17cm

Plot I: A right angle triangle

Area = ½ × base × height

Base = CD, height = AD

Using Pythagoras theorem

CD = √(AC² - AD)²

CD = √(13² - 12²) = √(169-144)

CD = √25 = 5

Area = ½ × 5 ×13= 32.5

Area plot I = 32.5cm²

Plot II: An equilateral triangle

Area of the equilateral triangle = a²/4 ×(√3)

√3=1.73

a = side = AC

Area = (13)²/4 ×(√3) = 42.25 × 1.73 = 73.0925

Area of Plot II = 73.09cm²

Plot III: A rectangle

Area of a rectangle = length × width

length = 7cm

width = 5cm

Area of plot III = 7×5 = 35cm²

Plot IV: A trapezium

Area of trapezium = ½(base 1 + base2) × height

Base 1= FE = CD

Base 2= GH

To get height using diagram 2. When you draw the lines from the two points on base1, you would have 1 rectangle in the middle with the two triangles by the side.

We would apply Pythagoras theorem to find h in the two right angled triangles:

Hypotenuse ² = opposite ²+adjacent ²

1st ∆: 9² = h²+a²

h² = 81-a²

2nd ∆: 15² = h² + (12-a)²

225 = h² +144 - 24a+ a²

225-144 = h²-24a+ a²

Insert value for h² in the 2nd

81 = 81-a² - 24a + a²

24a = 81-81

a= 0

h² = 81-0²

h = √81 = 9

Area of trapezium = ½(5+7) × 9

= 6 × 9

Area of plot IV= 54cm²

Total the area of field​ = area of plot I + area of plot II + area of plot III +area of plot IV

= 32.5 + 73.09 + 35+ 54

Total the area of Field​ = 194.59cm²

The ordered pairs for the system of equations f(x) = x^2 -2x + 3 and f(x) = -2x + 12 are (3, 6) and (-3, 18)

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0)

f(x) = x^2 -2x +3 and f(x) = -2x + 12

which means

x^2 -2x +3  = -2x + 12

x^2 -2x +3  + 2x - 12 = 0

x^2 -9 = 0

by factorizing we have

(x-3)(x+3) = 0

x = 3 or -3

when x = 3

f(x) = -2x + 12

f(3) = -2(3) + 12 which is 6

when x = -3

f(-3) = -2(-3) + 12 which is 18

ordered pairs are (3, 6) and (-3, 18)

In conclusion, (3, 6) and (-3, 18) are the ordered pairs

The Cartesian coordinate system is also referred to as a plane because it represents a two-dimensional space.

In mathematics, a plane is a flat surface that extends infinitely in all directions. The Cartesian coordinate system consists of two perpendicular lines, known as the x-axis and y-axis, which intersect at a point called the origin. These axes divide the plane into four quadrants.

The term "plane" in the context of the Cartesian coordinate system originates from the concept of a geometric plane, which is a fundamental concept in Euclidean geometry. In Euclidean geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions.

The Cartesian coordinate system borrows this concept and applies it to represent points, lines, curves, and shapes in a two-dimensional space.

By using the Cartesian coordinate system, we can assign coordinates (x, y) to any point in the plane, where the x-coordinate represents the horizontal position and the y-coordinate represents the vertical position.

This system allows us to precisely locate and describe objects or phenomena within the two-dimensional space, making it a valuable tool in various fields such as mathematics, physics, engineering, and computer graphics.

The average velocity for the [3,4] is 27m/s and for [4,5] is 37m/s

The average velocity can be found by taking the derivative of the position function and evaluating it at the midpoint of the interval.

The average velocity on the interval [3,4] is given by (s(4) - s(3)) / (4 - 3), which is equal to (s(4) - s(3)) / 1. Using the position function, s(t) = 5t^2 - 8t + 13, we find that s(4) = 5(4²) - 8(4) + 13 = 61 and s(3) = 5(3²) - 8(3) + 13 = 34. Therefore, the average velocity on the interval [3,4] is (61 - 34) / 1 = 27 m/s.

The average velocity on the interval [4,5] is given by (s(5) - s(4)) / (5 - 4), which is equal to (s(5) - s(4)) / 1. Using the position function, s(t) = 5t² - 8t + 13, we find that s(5) = 5(5²) - 8(5) + 13 = 98 and s(4) = 5(4²) - 8(4) + 13 = 61. Therefore, the average velocity on the interval [4,5] is (98 - 61) / 1 = 37 m/s.

The height of the school building is 12.34 meters, rounded to the nearest hundredth of a meter.

Nakeisha's method of using a mirror on the ground to measure the height of her school building is based on the principles of similar triangles. When she places the mirror on the ground and steps away from it, she creates two triangles, one from her eyes to the mirror and the other from the mirror to the top of the school building. These two triangles are similar, which means that they have the same shape but different sizes.

To find the height of the school building, we need to use the ratios of the corresponding sides of the two similar triangles. Let's call the height of the school building "h". Then, the distance from Nakeisha's eyes to the mirror is (1.25 + 1.65) = 2.9 meters, and the distance from the mirror to the school building is (8.65 - 1.65) = 7 meters.

Using the ratios of the corresponding sides, we can set up the proportion:

h/7 = 2.9/1.65

Cross-multiplying and solving for h, we get:

h = 7 x (2.9/1.65) = 12.34 meters

It's important to note that this method of measuring height using a mirror on the ground assumes that the ground is flat and level. If there are any slopes or uneven surfaces, the results may be inaccurate. Additionally, it's crucial to take all necessary safety precautions when conducting any measurements from heights or near busy roads.

The equation holds true, confirming that (-5, 2) is indeed the solution to the given equation.

To complete the missing value in the solution to the equation x - 5y = -15, we substitute the given x-value (-5) into the equation and solve for y.

Substituting x = -5 into the equation, we have:

-5 - 5y = -15

Next, we simplify the equation by combining like terms:

-5y = -15 + 5

-5y = -10

To isolate y, we divide both sides of the equation by -5:

y = (-10) / (-5)

Simplifying further, we have:

y = 2

Therefore, the missing value in the solution to the equation is y = 2.

In the ordered pair form, the solution is represented as (-5, 2), where -5 corresponds to the x-value and 2 corresponds to the y-value.

This means that when x is equal to -5, and y is equal to 2, the equation x - 5y = -15 is satisfied. Plugging in these values into the equation:

-5 - 5(2) = -15

-5 - 10 = -15

Step-by-step explanation:

Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2

x is the number of feet away from the sprinkler head the spray

To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;

From the equation

ℎ(x)=160−16x^2

h(2) = 160-16(2)²

h(2) = 160-16(4)

h(2) = 160-64

h(2) = 96feet

Hence the height will be 96feet if the spray is 2feet away from the sprinklers head
