If the two shakes below are similar, calculate the value of x.

X=

Answer:

h'(1) = 19

Step-by-step explanation:

if h(x) = f(x) + g(x), and f(x) = x³ and g(x) = 4x⁴,

then h(x) = (x³) + (4x⁴)

h(x) = x³ + 4x⁴

h'(x) is the derivative of h(x), which = 3x² + 16x³. Thus, h'(1) = 3(1)² + 16(1)³ = 19

(I) Break even sales: S = 40,000

(ii) Sales needed to earn a profit  Rs 6000 per period: S = Rs. 45,000.

The formula for the Break even sales is:

(S‐v) /S= F + P  

s x P/V Ratio = Contribution

First calculate P/V Ratio:

P/V Ratio = Contribution/sales x 100

P/V Ratio = (40‐24)/40 x 100

P/V Ratio= 16/40 x 100

P/V Ratio = 40%

(I) Break even sales  

S x P/V Ratio = Fixed Cost

For break even sales, deposition equals fixed cost.

Thus,

Put the values:

S x 40/100 = 16,000

S = 16,000 x 100 / 40

S = 40,000

S = 1000 units

(II) Sales to gain a profit of Rs. 6,000

S x P/V Ratio = F + P

Put the values:

S x 40/100 = 16000 + 2000

S = 18,000 x 100/40  

S = Rs. 45,000

S =  1125 units

the answer is 42 will be 42 because i answer that before

Answer:

Step-by-step explanation:

The cable company offers Erik 3 free months of cable if he signs a contract with them for $40 per month. This means that Erik will pay for (m - 3) months of cable service, since he will get 3 months for free. So the cost of the cable service for (m - 3) months is:

Cost = $40 per month x (m - 3) months

Cost = $40m - $120

We know that Erik spent $680 for the cable television service. So we can set up an equation to relate the cost to the number of months:

$40m - $120 = $680

To solve for m, we can isolate the variable on one side of the equation:

$40m = $800

m = 20

Therefore, Erik will have cable television service for 20 months with this deal.

Step-by-step explanation:

radius is 1/2 the diamiter

Answer:

Step-by-step explanation:

Answer: 6 inches.

Explanation:

Since the radius is 3 inches, the diameter will be twice the size of the radius. The radius is half the width of a circular object. The diameter is the full width. Therefore Omar's lollipop has a diameter of 6 inches.

The point after 30, 000 km will they first have to change the oil, rotate the tires and replace the wiper blades all at once.

Arithmetic Progression (AP) is a numerical series in which the difference between any two consecutive numbers is a constant value. Arithmetic Sequence is another name for it.

The First term is an "oil change" with a step d = 3000 km;

and, the second term is tire rotation = 10, 000 Km

and, the third term is replacement of wiper blades = 15, 000 Km

Now, we know from the formula of Arithmetic Progression is

= + d(n-1)

So, 15,000 = 10,000 + 10,000 (n-1)

15, 000 = 10,000 + 10, 000n- 10,000

150000 = 10000n

n = 1.5

This means that at the point 15 000 km and all three progressions will not intersect.

Now, We take the second term of the progression as  = 30,000 km

So, 30,000 = 10,000 + 10,000 (n-1)

20,000 = 10,000n - 10,000

30, 000 = 10,000n

n= 3

Similarly, check this intersection point for the first progression with a step of d = 3 000 km we get n =9.

Therefore, the z-score of a data value x = 21 is 0.

Answer: 0.

Data are pieces of information that have undergone modifications to make them transferable or computer-processable. For usage with modern computers and communication networks, data is information that has been converted into binary digital form. The topic of the data is admissible in both its singular and plural variants.

To find the z-score of a data value x, we use the formula:

z = (x - μ) / σ

where:

x is the data value

μ is the mean

σ is the standard deviation

In this case, we are given the mean μ = 21 and the standard deviation σ = 1.2. The data value x is also equal to 21.

Substituting the values into the formula, we get:

z = (21 - 21) / 1.2 = 0 / 1.2 = 0

Therefore, the z-score of a data value x = 21 is 0.

The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6.7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.

Geometric sequences are used to represent growth and decay. The common ratio determines whether the sequence is increasing (if r > 1) or decreasing (if 0 < r < 1). When the common ratio is a whole number, such as 2 or 3, the terms in the sequence are whole numbers as well.

Geometric sequences are sequences where each term is found by multiplying the previous term by a fixed number, called the common ratio. In this case, the first term is 7 and the common ratio is -3, so each term is found by multiplying the previous term by -3. This means that the second term is 7(-3) = -21, the third term is -21(-3) = 63, the fourth term is -63(-3) = -189, and so on. By using the formula a7 = ar6 and substituting in the first term and common ratio, the 7th term can be calculated as -126.

The 7th term of a geometric sequence is calculated by using the formula a7 = ar6, where a is the first term and r is the common ratio. The first term in this sequence is 7 and the common ratio is -3, so the formula for the 7th term, a7, can be written as a7 = 7(-3)6. To calculate this, the exponent 6 must be multiplied by -3, giving -18. 7 multiplied by -18 is equal to -126, so the 7th term in this geometric sequence is -126.

A sample is described as a smaller, more manageable representation of a larger group. a smaller population with characteristics of a larger one. A sample is used in statistical analysis when the population size is too large to include all participants or observations in the test.

The sample may be biased if it is taken from the first 25 batteries made each day (option A) or the last 25 batteries made each day (option B).

The first and final batteries made each day could not be an accurate representation of the total quality of the batteries produced that day if the battery manufacturing process is not consistent throughout the day.

Although battery quality can change during the day, sampling the first 50 batteries produced each day (option C) may also add bias into the sample.

The ideal course of action is to randomly select 50 batteries throughout the day (option D), since this helps to ensure that the sample is reflective of the general caliber of batteries manufactured that day.

Random sampling reduces the possibility of bias into the sample.

A polynomial is an expression containing algebraic terms that consists of variables and coefficients, joined together by operators.

The expression is 15·x² + 25·x - 10

Part A; The greatest common factor of the polynomial is the value that divides each of the terms of the polynomial, therefore;

The greatest common factor of 15·x² + 25·x - 10 is obtained as follows;

The largest number that divides each term of he polynomial expression is 5

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2)

Part B; The expression, 15·x² + 25·x - 10, can be factored as follows;

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2)

3·x² + 5·x - 2 = 3·x² + 6·x - x - 2

3·x² + 6·x - x - 2 = 3·x·(x + 2) - 1·(x + 2) = (3·x - 1)·(x + 2)

3·x² + 5·x - 2  = (3·x - 1)·(x + 2)

15·x² + 25·x - 10 = 5·(3·x² + 5·x - 2) = 5·(3·x - 1)·(x + 2)

Factoring the expression completely, we get;
