Answer:

(f+6) (x)= x^3+3x^2+1 / x2

Step-by-step explanation:

Using the Factor Theorem, it is found that none of these options represent a linear factor of f(x) = x³ + 7x² + 4x - 12.

The Factor Theorem states that if x - a is a factor of the polynomial y = f(x), then f(a) = 0.

The polynomial for this problem is defined as follows:

f(x) = x³ + 7x² + 4x - 12.

The numeric values for each of the options are given as follows:

As none of the values of a have f(a) = 0, none of these terms are linear factors of the polynomial x³ + 7x² + 4x - 12.

1000 ml of sodium silicate is used to make 10 liters soap

An equation is a expression that shows the relationship between numbers and variables.

The standard form of a linear equation is:

y = mx + b

Where m is the rate of change and b is the y intercept

Let y represent the amount of sodium silicate in x ml of liquid soap.

From the graph, using the points (1000, 100) and (3000, 300):

y - 100 = [(300 - 100)/(3000 - 1000)](x - 1000)

y - 100 = 0.1(x - 1000)

y = 0.1x

For 10 L (10000 ml)of soap:

333 integers,  there are 333 integers between 1 and 1,000 which are divisible by 3, by divisibility test.

The divisibility rule is a concise and practical approach to check, often by looking at the integer's digits, whether a given integer is divisible by a given set divisor without actually executing division. Without actually doing the division procedure, you may quickly discover if a given number can be divided by a defined divisor using the divisibility test. When dividing two numbers exactly, the quotient must be an integer and the remainder must be zero.

Therefore , the solution of transformation of function is Translation shifting the graph of a function up or down, or left or right.

A transformation of a function is a new function that is derived from the original function by applying some mathematical operation. The process of creating a new function from an existing one by applying a mathematical operation is called a transformation.

Here,

There are different types of transformations that can be applied to a function, such as:

Translation: shifting the graph of a function up or down, or left or right.

Reflection: flipping the graph of a function over the x-axis, y-axis, or a line of symmetry.

Stretching or compressing: changing the scale of the graph along the x-axis or y-axis.

Rotation: rotating the graph of a function about the origin.

Function G is a transformation of function f. G(x) = x^2

A transformation of a function is a new function that is derived from the original function by applying some mathematical operation. In this case, function G is derived from function f by squaring the input value. The result is a new function that maps the input value to its square. The notation G(x)= x^2 is a common notation to represent a function and it means that G is a function that takes x as input and returns the square of x as output.

Answer:

[tex]\dfrac{155}{18} \pi \textrm{ cm}[/tex]

Step-by-step explanation:

This problem asks us to find the length of an arc ACB on the circumference of a circle with center O and a radius of 5 cm.

We first must solve for the total circumference (perimeter) of the circle. This is represented by the formula C = 2πr. Hence, the circumference of this circle is:

C = 2π(5) cm

C = 10π cm

Next, we have to find what fraction of 360º the major arc ACB is in order to deduce how much of the circle's total circumference the arc takes up.

[tex]\dfrac{(360 - 50)\textdegree}{360\textdegree} = \dfrac{31}{36}[/tex]

Finally, we can multiply the amount of circumference that arc ACB takes up by the length of the whole circumference to get the length of arc ACB.

[tex]\textrm{Length of arc } ABC = \dfrac{31}{36} \cdot 10\pi[/tex]

[tex]= \dfrac{310}{36} \pi[/tex]

[tex]= \dfrac{155}{18} \pi \textrm{ cm}[/tex]

Answer:

[tex]\textsf{Length of major arc $\overset{\frown}{ACB}$}: \;\; \boxed{\dfrac{155}{18}\pi\; \sf m}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $= \pi r\left(\dfrac{\theta}{180^{\circ}}\right)$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in degrees.\\\end{minipage}}[/tex]

Angles around a point sum to 360°.  Therefore:

[tex]\begin{aligned}\implies m \angle BOA&=360^{\circ}-m \angle AOB\\&=360^{\circ}-50^{\circ}\\&=310^{\circ}\end{aligned}[/tex]

Therefore, the given values are:

To find the length of the major arc ACB, substitute the given values into the arc length formula:

[tex]\begin{aligned}\implies \overset{\frown}{ACB}&=\pi \cdot 5 \cdot \left(\dfrac{310^{\circ}}{180^{\circ}}\right)\\\\&=5\pi \cdot \dfrac{31}{18}\\\\&=\dfrac{155}{18}\pi\; \sf m\end{aligned}[/tex]

Equalizing ratios refer to two ratios with the same value.Multiply or divide both values by the same number to arrive at an equivalent ratio. The ratio 1: 3.5 will be the equivalent of the ratio 8: 28.

where each of the two variables, x and y, is a separate quantity.Additionally, the combined total is given as x + y.

Knowing that;

is the ratio;

8 : 28

And the ratio has the following equivalent form: 1: n.

Now,

The ratios 8: 28 and 1: n are identical, thus.

in order to formulate;

The value of the sales tax applied to the bill is $0.36

If we have an initial value A, and we increase it by a percentage X, then the new value (after the increase) is given by:

A' = A*(1 + X/100%).

Here we know that the bill before the tax and the tip (it will be the initial value) is:

A = $11.85

And a sales tax of 3% is applied to that bill, then the new amount is:

A' = $11.85*(1 + 3%/100%)

A' = $11.85*(1 + 0.03) = $12.21

Step-by-step explanation:

Had our given compound inequality been:

   x < -5 or x > 5

Then the boundary values (-5) and (5) would have contained open circles to show that these values are not included in the solution sets for these inequalities.

The inequality which represents the number of backpacks need to be sold is 40x - (10x + 12,000) ≥ 980. Factory should sell at least 433 backpacks in a week.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Selling price of 1 backpack = $40

Cost to make 1 backpack = $10

Operating expense per week = $12,000

Let x be the number of backpacks which are sold in a week.

Total revenue per week = 40x

Total expense per week = 10x + 12,000

Profit = Revenue - Expense

         = 40x - (10x + 12,000)

Factory's goal is to make a profit of at least $980 each week.

40x - (10x + 12,000) ≥ 980

This is the inequality that represents the number of backpacks need to be sold.

Solving the inequality,

40x - (10x + 12,000) ≥ 980

40x - 10x - 12,000 ≥ 980

30x ≥ 980 + 12,000

30x ≥ 12,980

x ≥ 432.67 ≈ 433

Hence factory must at least a total of 433 backpacks to meet it's weekly goal of $980.

A child can receive 0.5 kg /ml of drug.

What is density?

It is the quantity of a substance per unit volume. A   quantity of mass is divided by volume, and we get a density of a particular substance.

A 66 lb. child can receive 1 meq/ kg of drug.

but the drug is available in 2 meq/ 4ml.

we need to divide kg by ml to estimate how much quantity is suitable.

From the standard unit, if we divide the quantity in kg by the quantity in ml we achieve a density of drug.

(1 meq / kg) / (2 meq/ 4ml) = 2 ml / kg

the above value is inversed, and we get a density.

For a lower-tail test, a t-statistic that is negative and far from zero would then lead us to favor the alternative hypothesis

An alternative way to conduct a hypothesis test is to again assume initially that the null hypothesis is true, but then to calculate the probability of observing a t-statistic as extreme as the one observed or even more extreme

For a lower-tail test, the p-value is the area under the curve of the t-distribution (with n−1 degrees of freedom) to the left of the observed t-statistic.

Lower-tail tests work in a similar way to upper-tail tests, but all the calculations are performed in the negative (left-hand) tail of the t-distribution density curve

A lower-tail test would result in an inconclusive result for the home prices example (since the large, positive t-statistic means that the data favor neither the null hypothesis, NH: E(Y) = 255, nor the alternative hypothesis, AH: E(Y) < 255).
