Answer:

g(-6) = -6

g(0) = 5

g(7) = 8

h(-6) = 10

h(0) = -1

h(7) = -4

Step-by-step explanation:

g(x) = (1/3) f(x)

g(-6) = (1/3)(-18) = -6

g(0) = (1/3)(15) = 5

g(7) = (1/3) (24) = 8

h(x) = -g (x) + 4

h(-6) = -(-6) + 4 = 10

h(0) = -(5) + 4 = -1

h(7) = -(8) + 4 = -4

Answer:

y = (-1/6)x - 4

Step-by-step explanation:

Line equations are usually expressed in the following format:

y = mx + c

Where m is the gradient (slope), and c is the y-intercept.

We can fill in the value of m right away as we are given it in the question:

y = (-1/6)x + c

And we are given the point (-6,-3), so we can fill in the values for x and y, in order to find the value of c:

-3 = (-1/6)(-6) + c

Rearrange and simplify this:

-3 = 1 + c

c = -4

Finally, substitute the value of c back into the original equation to get the final equation of the line:

y = (-1/6)x - 4

The line joining the midpoints of two sides of a triangle is parallel to the third side and half its length.

Triangle law of vectors states that for a ΔABC

The sum of vectors of two sides is equal to the third side vector.

Two vectors are said to be Parallel if one vector is scalar multiple of other.

In the given figure

In ΔABC , D is mid point of AB and E is the mid point of AC .

By using triangle law of vectors for ΔADE

AE+AD=ED......(1)

Now using triangle law of vectors addition for ΔABC

CA+AB=CB    ....(2)

(as given that E is the mid point of CA , we can write [tex]AE=\frac{1}{2} CA[/tex]

CA=2AE.....(3)

and D is mid point of AB , we can write [tex]AD=\frac{1}{2} AB[/tex]

AB=2AD......(4)

Substituting (3) & (4) in (2) we get

2AE+2AD=CB

2(AE+AD)=CB

SUBSTIUTTING VALUES OF (AE+AD) from (1) we get

2ED=CB

[tex]ED=\frac{1}{2} CB[/tex]

Hence , the line joining the midpoints of two sides of a triangle is  half of third side.

Since ED is (1/2) of CB i.e. ED is scalar multiple of CB.

Hence they are parallel.

Therefore , The line joining the midpoints of two sides of a triangle is parallel to the third side and half its length.

If slopes of the given lines are solved and observed, we get the slope of line E is [tex]m_{E}[/tex] = [tex]\frac{-5}{6}[/tex]

As per question statement, the equation for line A is [tex]y = \frac{6x}{5} - 10[/tex] Line A is parallel to line B, which is perpendicular to line C. The line D is perpendicular to line C and perpendicular to line E.

Before solving this question, we need to know about some basic formulas and concepts of equation for a line.

If Lines are parallel, their slopes are equal and if lines are perpendicular, the product of their slopes is -1.

i.e., if [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are slopes of two lines then if,

[tex]m_{1} = m_{2}[/tex] then lines are parallel

Now slope of line A can be found out by formula [tex]y=mx+c[/tex] hence slope of line A   [tex]m_{A}[/tex]= [tex]\frac{6}{5}[/tex]

Line B is parallel to A so, [tex]m_{B}[/tex] = [tex]\frac{6}{5}[/tex]

Line C is perpendicular to B so [tex]m_{C} * m_{B} = -1\\m_{C} = \frac{-5}{6}[/tex]

Line D is perpendicular to C so [tex]m_{D} *m_{C} = -1\\m_{D} = \frac{6}{5}[/tex]

Line E is perpendicular to D hence [tex]m_{E} * m_{D} = -1\\m_{E} = \frac{-5}{6}[/tex]

Therefore the slope of line E is [tex]\frac{-5}{6}[/tex]

The basic equation used to demonstrate and overcome for an unknown quantity is a linear equation for one variable.

The given equation is;

18 − 15 = − 2x/5 + 7x/15

Simplifying the constant and variable part.

- 3 = 5x/5

Multiplying both side by 5;

Thus, 36° is the smaller angle and 144° is the greater angle.

For instance, the complement angle of 130° and the angle of 50° is 180°. Complementary angles add up to 90 degrees. When the two extra angles are combined, they create a straight line and an angle. The two angles that complement one another do not necessarily need to be close to one another, it should be emphasised. As a result, two angles may be supplementary if their sum is 180 degrees.

The degree of the polynomial formed is 6.

The degree of a polynomial is the highest degree of the variables present with non-zero coefficients.

For example the polynomial has three 7x³y²+9xy+4 terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term.

Now the given functions are:

[tex]f(x)=x^3[/tex] ,g(x)=3x²-1 and h(x)=2x

Now we have to find (f ° g° h)(x). Let us first find (g°h)(x).

(g°h)(x) is equal to g[h(x)]

=g[2x+5]

=3(2x+5)²-1

=3(4x²+20x+25)-1

=12x²+60x+74

Now we find (f ° g° h)(x)

(f ° g° h)(x)=f[g(2x+5)]

f[g(2x+5)]=f(12x²+60x+74)

f(12x²+60x+74)=(12x²+60x+74)³

Now we have to simplify the expression:

(12x²+60x+74)³

=[tex]1728x^6+25920x^5+161568x^4+535680x^3+996336x^2+985680x+405224[/tex]

According to the given statement,

366 liters of natural oil is needed to make 671 L synthetic oil.

Essential oils, which are more natural, are slightly different from synthetic oils. An intentionally created chemical component is present in synthetic oils, which are used as lubricants.

Full synthetics and semi-synthetic oils are the two primary types of synthetic oils. Full synthetics originate from crude oil or byproducts in this situation. Conventional oils are produced using chemical procedures rather than distillation. The resulting synthetic oil has a higher molecular make-up and frequently exhibits more consistent characteristics. Synthetic oils are used in many cosmetic and medicinal goods, just like their more natural equivalents.

According to the given values;

The ratio of natural to synthetic oil

= 6:5

If 671 liters have to be made then,

It is not possible that the intersection case is P(A B)=0.5 .

The set of all objects that are members of both sets A and B is represented by the intersection of the two sets A and B, abbreviated as A∩B.

If there is any element x that is an element of both A and B, then we can also say that A intersects (meets) B at x. If A∩B is an inhabited set, which means that there must be some x such that x∈A∩B exists, then A intersects B equivalently.

If A does not intersect B, then A and B are said to be disjoint. They share no elements, to put it simply. If the intersection of A and B contains nothing—A∩B=Ф—then A and B are disjoint.

Explanation:

The likelihood of occurring of an event is called probability.

Consider two events A and B are occurred with probabilities P(A) and P(B)  respectively.

The probability that both the events occurs is,

P(A and B)=P(A∩B)

When both the events are independent,

P(A and B)=P(AB) = P(A)x P(B)

The probability that either A or B occurs is,

P(A or B)= P(AUB) = P(A)+P(B)-P(A∩B)

When both the events are mutually exclusive the probability that either A or B occurs is,

P(A or B)=P(AUB) = P(A)+P(B)

The compliment of the probability is,

P(A)=1-P(A)

The conditional probability of occurring of an event A when it is given that B had already occurred is,

P(A|B)=P(A∩B)/P(B)

Let A represent the situation where the chosen person has a Visa credit card and B represent the situation where they have a Master card. The probability of occurring event A is 0.6 and the probability of occurring event B is 0.4 that is, P(A)=0.6, P(B)=0.4 .

It is known that P(A B)∠P(A) and P(A B)∠P(B) . So, it is not possible that the intersection case, P(A B)=0.5 .

The area of a persian rug in a metre square is given by 10.03 m2. It is calculated by using the concept of area and conversion of units of a quantity.

What is the conversion of units?

Conversion of units is the transformation between various units of measurement for the same quantity, simply the conversion of units deals with converting a quantity into different units without changing its magnitude.

Calculation of the area of the persian rug with given width and length

Given:

Length = 12 feet

Width = 9 feet

The basic step involved in solving this problem is to convert the length and width given in feet into metre

We know that 1 feet = 0.3048 m

Length = 12 × 0.3048

           = 3.657 m

Width = 9 × 0.3048

         = 2.743 m

Area of rug = length × width

=  3.657 × 2.743

= 10.03 m2

Hence, the required area of the persian rug is 10.03 m2.
