Suppose That The Functions U And W Are Defined As Follows.u(x) ==-x-1w(x) = 2x +1Find The Following.

Answers

Answer 1

Step-by-step explanation:

(a○b)(x) is the same as a(b(x)).

it is really that simple.

first you calculate the result of the inner function, and then that result is the input for the outer function.

that's it.

so,

(w○u)(2) = w(u(2))

u(2) = -2 -1 = -3

w(-3) = 2×(-3)² + 1 = 2×9 + 1 = 19

so, 19 is the first answer.

(u○w)(2) = u(w(2))

w(2) = 2×2² + 1 = 2×4 + 1 = 9

u(9) = -9 - 1 = -10

so, -10 is the second answer.

Answers

1.

In this equation, 2x + 6 has to be greater than or equal to y. You must substitute each coordinate into the equation and evaluate to find the correct answer. In this case, the answers are (-10, -20) and (7, 14).

2.

Same goes for this problem. The answers are (11, -32) and (-6, -2).

3.

Since we are given the line equation, we just determine the operator to use. Because it is a dotted line, that means that the point on the line is not included, so we will use a regular <>. Because the space highlighted indicates that -10x - 6 will always be greater than y, the answer is y < -10x-6, or C.

4.

We are given the line equation here as well. Since the boundary line is not dotted, we include the values, meaning we use [tex]\leq \geq[/tex]. Since the highlighted space indicates that y is always greater than or equal to x-5, the answer is [tex]y\geq x-5[/tex], so the answer is B.

Hello!

y=1/2x-3 is steeper than y=1/4x-8.

We calculate the slope using Rise/Run.

The rise is 1, and the run is 2 (how many units we move left of right)

If you graph these lines, you will see that the line y=1/2x-3 is steeper than y=1/4x-8

the length of a cuboid is 3 times of it's height and it's breadth is 2 times it's height if the volume of the cuboid is 48000cm cube, calculate it's dimensions​

Answers

Answer:

The length, breadth and height of cuboid are 60 cm, 40 cm and 20 cm.

Step-by-step explanation:

Let,

The height of cuboid be X cm.The length of cuboid is three times of it's height. So, it will be 3x.The breadth of cuboid is two times of it's height. So, it will be 2x.

Now, substuting all the given values in the formula to find the value of x.

[tex]\longrightarrow{\sf{V_{(Cuboid)} = l \times b \times h}}[/tex]

➝ V = Volume ➝ l = length ➝ b = breadth➝ h = height

[tex]\begin{gathered} \qquad\longrightarrow{\sf{V_{(Cuboid)} = l \times b \times h}}\\\\\qquad\longrightarrow{\sf{48000 = 3x \times 2x \times x}}\\\\\qquad\longrightarrow{\sf{48000 = 3x \times 2{x}^{2}}}\\\\\qquad\longrightarrow{\sf{48000 = 6{x}^{3}}}\\\\\qquad\longrightarrow{\sf{{x}^{3} = \dfrac{48000}{6}}}\\\\\qquad\longrightarrow{\sf{{x}^{3} = 8000}}\\\\\qquad\longrightarrow{\sf{x = \sqrt[3]{8000}}}\\\\\qquad\longrightarrow{\sf{x = 20}}\\\\ \qquad{\star{\underline{\boxed{\sf{\purple{x = 20}}}}}} \end{gathered}[/tex]

Hence, the value of x is 20.

Now, we know the value of x. So, calculating the dimensions of cuboid :

Length = 3x

➝ 3 × 20➝ 60 cm

Breadth = 2x

➝ 2 × 20➝ 40 cm

Height = x

➝ 1 × 20➝ 20 cm

Which is bigger 12 cm or 102 mm

Answers

12 CM!!!!!!!!!!!!!!!!!!!!

On comparing the quantities 12 cm or 102 mm, 12 cm (120 mm) is greater than 102 mm.

To compare the sizes of 12 cm and 102 mm, both numbers should have the same unit.

Now, the conversion factor cm and mm is

1 cm = 10 mm

Then, using the conversion factor convert 12 cm to mm

12 cm = 12 x 10 mm

         = 120 mm

Now, compare 120 mm and 102 mm which gives 120 mm is greater.

Thus, 12 cm is greater than 102 mm.
