A rhombus with MK = 24 m, JL = 20, ∠MJL = 50°. So, NK = 24 m, NL = 24.8 m, ML = 24.8 m, and JM = 20 m.

We need the information about the measurements or a description of the missing measures in the rhombus. We can make it MK = 24 m, JL = 20, ∠MJL = 50° for example. Since it's a rhombus, all sides are equal in length. Therefore, NK = MK = 24 m, JM = JL = 20 m, and ML = NL.

To find ML (or NL), we can use the Law of Cosines on the triangle MJL. In this case,

ML² = JM² + JL² - 2(JM)(JL)cos(∠MJL):

ML² = 20² + 20² - 2(20)(20)cos(50°)

ML² = 400 + 400 - 800cos(50°)

ML² ≈ 617.4

Taking the square root of both sides, we get ML ≈ √617.4 ≈ 24.8 m.

So, NK = 24 m, NL = 24.8 m, ML = 24.8 m, and JM = 20 m.

The complete question is The quadrilateral below is a rhombus. Given MK = 24 m, JL = 20, ∠MJL = 50°. Find NK, NL, ML, and JM. Any decimal answers should be rounded to the nearest tenth.

In the experiment, the independent variable is the amount of sunlight received by the clover plants.

The amount of sunlight the clover plants receive throughout the experiment serves as the independent variable, as it is being manipulated by the experimenters to determine its effect on the size of the clover leaves.

The dependent variable is the size of the clover leaves, which is being measured as a result of the change in the independent variable (amount of sunlight). The water is a controlled variable, as it is kept constant across both conditions to eliminate its effect on the outcome.

Given the information;

rubber chips costs $52.50 per square foot

We need to find the area of the playground,

The length: 8ft

The width: 4 ft

=> the area of it is: 8*4 = 32 square foot.

The base: 3 ft

The height: 2 ft

=> the area of it is = 1/2*3*2 = 3 square foot.

The base: 3 ft

The height: 3 ft

=> the area of it is = 1/2*3*3 = 9/2 square foot.

=> the total area of the playground is: 32 + 3 + 9/2 = 39.5 square foot.

So the total cost to install the rubber chips is:

= 39.5 * $52.5

= $2075.75

Hope it will find you well.

The $2625 is the cost to install the rubber chips if each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

First, we find the area of the rectangle = (8+3)×4 = 44 square feet

Area of the two triangle = 2(1/2)[2×3] = 6 square feet

Area of the complete figure = 44+6 = 50 square feet

Each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

Total cost = 50×52.50 = $2625

Thus, the $2625 is the cost to install the rubber chips if each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

Answer:

Step-by-step explanation:

When a tangent line is drawn from Q to Z and then from Q to R, what happens that is the length of QZ and QR are the same.  So if QZ = 10, the QR = 10. The same occurs at every point outside the circle where a tangent line is drawn from that point to the circle. We are told that YX is 9.  That means that YZ is also 9. If XW is 9, then WV is also 9. Here's where the tricky part is. We are given the whole side length of UW as 17, but we need to know each individual part so we can eventually find the length of RS. So we'll keep going the way we were. If XW = 9, the WV = 9. That means that UV is 17 - 9 or 8. So UV = 8. That means that TU is also 8. THAT means that ST is 10 - 8 or 2. And if ST is 2, then RS is also 2.  Let's add it all together now:

QZ + ZY + YX + XW + WV + VU + UT + TS + SR + RQ

10 +    9 +   9 +     9 +    9 +     8 +   8 +    2 +   2 +   10 = 76

The law of demand states that when the price of a good or service decreases, the quantity demanded increases, and vice versa.

The law of demand is an economic theory stating that the higher the price of a good, the lower the quantity demanded, and vice versa. When price decreases, the quantity demanded increases, and when price increases, the quantity demanded decreases. So, it's correct to say that according to the law of demand, if price goes down, demand goes up. Hence, the answer is True.

Let us understand this with an example:

If the price of a toy car is $10, there are ten buyers who want to purchase it. When the price of the same toy car is reduced to $8, the number of buyers who want to purchase it increases to fifteen. Because the price of the toy car is now cheaper than it was before, people are more willing to buy it;

hence the law of demand is validated.The law of demand is a fundamental principle in microeconomics that is crucial in making decisions regarding price and production. If demand is high, the price of the good or service may increase; and if demand is low, the price of the good or service may decrease. The law of demand is a fundamental concept that is essential for businesses, entrepreneurs, and investors. In summary, the law of demand states that when the price of a good or service decreases, the quantity demanded increases, and vice versa.

Answer:

x=84

Step-by-step explanation:

A. You should calculate the cost per unit to determine if the price of 1500 for 15 units is a good deal.

B. To determine whether the offer is a good deal, you need to calculate the cost per unit.

Divide the total price of 1500 by the number of units offered, which is 15.

Cost per unit = Total price / Number of units

Cost per unit = 1500 / 15

Cost per unit = 100

The cost per unit is 100.

Now, consider the value you assign to each unit of space. If you believe that each unit is worth more than 100, then the offer is a good deal and you should accept it.

However, if you believe that each unit is worth less than 100, then the offer is not favorable and you should decline it.

Ultimately, the decision depends on your evaluation of the worth of each unit of space and whether you believe the cost per unit is reasonable based on your needs and budget.

a) The second-degree Taylor polynomial for f about x=1 is 1.69

b) The third-degree Taylor polynomial for f about x=1 is 0.867

c) The second-degree Taylor polynomial for f' about x=1 is -0.4

a) The second-degree Taylor polynomial for f about x = 1 is:

f(x) ≈ f(1) + f'(1)(x-1) + (f''(1)/2)(x-1)^2

Plugging in the given values, we get:

f(x) ≈ 3 - 2(x-1) + (2/2)(x-1)^2

f(x) ≈ 1 - 2(x-1) + (x-1)^2

To approximate f(0.7), we substitute x = 0.7 in the polynomial:

f(0.7) ≈ 1 - 2(0.7-1) + (0.7-1)^2

f(0.7) ≈ 1 + 2(0.3) + 0.09

f(0.7) ≈ 1.69

Therefore, f(0.7) ≈ 1.69 using the second-degree Taylor polynomial.

b) The third-degree Taylor polynomial for f about x = 1 is:

f(x) ≈ f(1) + f'(1)(x-1) + (f''(1)/2)(x-1)^2 + (f'''(1)/6)(x-1)^3

Plugging in the given values, we get:

f(x) ≈ 3 - 2(x-1) + (2/2)(x-1)^2 + (4/6)(x-1)^3

f(x) ≈ 1 - 2(x-1) + (2/3)(x-1)^3

To approximate f(1.2), we substitute x = 1.2 in the polynomial:

f(1.2) ≈ 1 - 2(0.2) + (2/3)(0.2)^3

f(1.2) ≈ 0.867

Therefore, f(1.2) ≈ 0.867 using the third-degree Taylor polynomial.

c) The second-degree Taylor polynomial for f', the derivative of f, about x = 1 is:

f'(x) ≈ f'(1) + f''(1)(x-1)

Plugging in the given values, we get:

f'(x) ≈ -2 + 2(x-1)

f'(x) ≈ -2 + 2x - 2

f'(x) ≈ 2x - 4

To approximate f'(1.2), we substitute x = 1.2 in the polynomial:

f'(1.2) ≈ 2(1.2) - 4

f'(1.2) ≈ -0.4

Answer:

p(x) =  (x-5) (x+1)(4x+1)

Step-by-step explanation:

We know the equation for a polynomial with zeros is written as

f(x) = a( x-b1) (x-b2)...... where b are the zeros

We have zeros x = 5, x = -1, and x = -1/4

p(x) = a( x-5) (x- -1) (x - -1/4)

p(x) = a (x-5) (x+1) (x+1/4)

Let a = 4

p(x) = 4 (x-5) (x+1) (x+1/4)

p(x) =  (x-5) (x+1)(4x+1)

We can conclude that there is sufficient evidence at the 0.05 level to support the company's claim that more than 70% of computer chips do not fail in the first 1000 hours of their use.

In the given scenario, we have to determine if there is enough evidence to support the company's claim.

For this, we have to construct the null and alternative hypotheses.

The null hypothesis (H0) is that the proportion of computer chips that do not fail in the first 1000 hours of their use is equal to or less than 70%.

The alternative hypothesis (H1) is that the proportion of computer chips that do not fail in the first 1000 hours of their use is more than 70%.

H0: P ≤ 0.70H1:

P > 0.70

Where P is the true population proportion of computer chips that do not fail in the first 1000 hours of their use.

To check whether the given claim is true, we will perform a hypothesis test at the 0.05 significance level.

We know that sample proportion (p) = 0.73

Sample size (n) = 1700

Level of significance (α) = 0.05

Using the formula z = (p - P) / √(P(1-P)/n)z

= (0.73 - 0.70) / √(0.70(1-0.70)/1700)z

= 4.20

Since this is a one-tailed test and our alternative hypothesis is one-tailed, the critical z-value is 1.645 (for α = 0.05).

Since our test statistic value (4.20) is greater than the critical value (1.645), we reject the null hypothesis.

9 f(x) dx of f(x) = 5 for x < 5 x for x ≥ 5 is  53 when x is between 0 and 9.

What is integration ?

Integration is a fundamental concept in calculus, which is used to find the area under a curve and the total change of a function. It is the reverse process of differentiation and can be used to find the original function, given its derivative.

For f(x) = 5 for x < 5, we have

∫(5dx) from 0 to 5 = 5*(5-0) = 25

For f(x) = x for x ≥ 5, we have

∫(x dx) from 5 to 9 = (1/2)x^2 from 5 to 9 = (1/2)(9^2 - 5^2) = (1/2)(81 - 25) = (1/2)(56) = 28

So the definite integral of the piecewise function is

∫(9 f(x) dx) from 0 to 9 = ∫(5dx) from 0 to 5 + ∫(x dx) from 5 to 9 = 25 + 28 = 53,

Therefore , 9 f(x) dx of f(x) = 5 for x < 5 x for x ≥ 5 is  53 when x is between 0 and 9.
