The transformed function is g(x) = 20x-6.

The graph of the function y=f(ax) represents a Horizontal Shrink by a factor of "1/a" of the graph y=f(x) .

To find the horizontal shrink by a factor of 1/a we multiply the input by a .

In the given question

f(x)=5x-6 , is horizontally shrink by a factor of 1/4.

So we multiply the inputs by 4 .

On multiplying the inputs by 4 , we get

f(4x)=5(4x)-6        (...as 5*4=20)

Let g(x) represents the horizontal shrink of f(x) by factor 1/4 , So

g(x)=20x-6

Therefore , the horizontal shrink of the graph of f by a factor of 1/4 is g(x)=20x-6.

The volume of the object which is made up of two different cylinders will be 383 cubic inches.

Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

The object is made up of two cylinders. Then the volume of the object will be

V = π x (3)² x 8 + π x (5)² x 2

V = π(72 + 50)

V = 3.14 x 122

V = 383.08 ≈ 383 cubic inches

If the side's measure is 30 centimeters, then the side of a square measures 3 decimeters, is the "if-then" form of A side of a square measures 3 decimeters if the side's measure is 30 centimeters.

A statement with an assumption and a conclusion is known as a conditional statement (also known as an if-then statement). The hypothesis is the initial clause, or "if," part of a conditional statement which is followed by the second, or "then," component of a conditional statement is the conclusion. The theory led to the conclusion.

Thus, option B is correct which is, if the side's measure is 30 centimeters, then the side of a square measures 3 decimeters.

The correct option is D,  -√15 < -2.75 < -2 3/8 < 15/2.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The value of the given numbers in the decimal form can be written as,

-√15 = -3.873

√15 = 3.873

15/2 = 7.5

-15/2 = -7.5

2 3/8 = 2.375

-2 3/8 = -2.375

Now, let's check in which options are the numbers arranged correctly.

A.) -√15 < -2 3/8 < -2.75 < 15/2

Since -2 3/8 > -2.75. Therefore, this is wrong.

B.) 15/2 < -2 3/8 < -2.75 < -√15

Since -2 3/8 > -2.75. Therefore, this is wrong.

C.) 15/2 < -2.75 < -2 3/8 < -√15

Since 15/2 > -2.75. Therefore, this is wrong.

D.) -√15 < -2.75 < -2 3/8 < 15/2

This is correctly arranged.

The coordinate of B is (13, -3).

What is Midpoint of line?

Measure of Distance between the two points and then divide by two is known as midpoint of line.

Given that;

The midpoint of the line AB is M (-5, 0).

The coordinate of A is (-3, 3).

Now, Let the coordinate of the point B is (x, y )

Then, By definition of midpoint of two point,

(-3 + x / 2 , 3 + y / 2 ) = (-5, 0)

By compare we get;

-3+ x / 2 = -5

- 3 + x = 2 * 5

- 3 + x = 10

x = 10 + 3

x = 13

And, 3 + y / 2 = 0

3 + y = 0

y = -3

Hence, The coordinate of B (x, y) = (13, -3).

Answer:

2yds 33 in

Step-by-step explanation:

Convert everything to the lowest unit(inches) perform the operation and convert back

1 yard = 3 feet
1 foot = 12 in
1 yard = 3feet x 12in = 36 in

19yd, 28in = 19 x 36 + 28 = 684 + 28 = 712 in

16yd, 31 in= 16 x 36 + 31 = 576 + 31 = 607 inches

19yd, 28in - 16yd, 31 in = 712 - 607 = 105 inches

Divide by 36 to get the whole number of yards as quotient
105/36  with remainder of 33

∴ 19yd, 28in - 16yd, 31 in = 105 inches = 2yds 33 inches

We can verify this by converting 2yds 11inches to inches and seeing the values agree

2 yds 33 in = 2 x 36 + 33 = 105

The sum of two odd integers is an even integer. Therefore, the set S is not closed under addition.

The following subsets of Z (with ordinary addition and multiplication) satisfy all but one of the

axioms for a ring. In each case, which axiom fails?

(a) The set S of odd integers.

• The sum of two odd integers is an even integer. Therefore, the set S is not closed under addition.

Hence, Axiom 1 is violated.

(b) The set of nonnegative integers.

• If a is a positive integer, then there is no solution of a + x = 0 that is also positive. Hence, Axiom

5 is violated.

In general, to show that a subset S of a ring R, is a subring of R, it is sufficient to show that

(i) S is closed under addition in R

(ii) S is closed under multiplication in R;

(iii) 0R ∈ S;

(iv) when a ∈ S, the equation a + x = 0R has a solution in S.

Let a, b, c ∈ S ⊂ Z with a = rk, b = sk, c = tk.

(i) a + b = rk + sk = (r + s)k ∈ S

(ii) ab = (rk)(sk) = (rsk)k ∈ S

(iii) 0Z = 0 = 0 · k ∈ S

(iv) a = rs ∈ S ⇒ x = −rs ∈ S is a solution ofa + x = 0S

Thus, S is a subring of Z.

Answer: 9.5 and 9.500

Answer:

One would be 9/5 and another could be 1.8

you can choose any of the 3 items, or any combination of two of the items unless the hair dryer and the boots, because the combined weight is 3.6lb + 2.5lb = 6.1 lb

The maximum weight that your bag can have is 50 pounds.

The actual weight of your bag is 44.9 pounds, so if we define x as the weight you can add, then we can write the inequality:

44.9 lb + x ≤ 50lb

Solving the inequality for x, we get:

x ≤ 50lb - 44.9 lb

x ≤ 5.1 lb

Now, the weight of the items are:

hair dryer = 2.5 lb

souvenir = 1.3 lb

boots = 3.6 lb

So you can choose any of the 3 items, or any combination of two of the items unless the hair dryer and the boots, because the combined weight is 3.6lb + 2.5lb = 6.1 lb
