What is simplification of an expression?

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.

For the given situation,

The expression is  $x^{6} + (y^{2} \div z^3)\cdot w^3$

⇒ [tex]x^{6}(\frac{y^{2} }{z^{3} } )(w^{3} )[/tex]

Substitute $x=2$, $y=3^2$ = 9$, $z=3$, and $w=4$,

⇒ [tex]2^{6}(\frac{9^{2} }{3^{3} } )(4^{3} )[/tex]

⇒ [tex]64+(\frac{81}{27} )(64)[/tex]

⇒ [tex]64+(3)(64)[/tex]

⇒ [tex]64+192[/tex]

⇒ [tex]256[/tex]

Hence we can conclude that the value of the expression is 256.

The graph shows the cube root parent function.

Answers

Answer: C

Step-by-step explanation:

The function is always increasing

The function is increasing when x>0 for the graph of [tex]y= \sqrt[3]{x}[/tex] as parent function.

What is graph?

" The graph is defined as the representation of relation between two variables on the coordinate plane."

According to the question,

Given graph of the  cube root parent function

For function [tex]y= \sqrt[3]{x}[/tex]

x = 0 ⇒ y = 0

x = 1 ⇒ y = 1

x = 8  ⇒ y = 2

x = 27 ⇒ y = 3

Therefore, for x>0, function [tex]y= \sqrt[3]{x}[/tex] is increasing.

Hence, Option(D) is the correct answer.

Work out the perimeter of a rectangle with length 8.5cm and width 0.2cm.

Answers

Answer: 17.4 cm

Step-by-step explanation: All you have to do is add all of the sides together.

So 8.5+8.5+0.2+0.2

=17+0.4

=17.4 cm

Answer:

17.4 cm

Step-by-step explanation:

A rectangle has two sets of parallel, equal sides. So that means two of the sides are equal to 8.5cm and the other two sides are equal to 0.2cm. When you put that in an equation:

8.5 + 8.5 + 0.2 + 0.2 = 17.4

which of the number 285, 627, 5490, 7290, 7295, 15780, 43695 are divisible by 5 but not 3

Answers

Answer:

Step-by-step explanation:

They all end in 0 or 5 except 627, so all but 627 are divisible by 5.

The following are divisible by 3

285

627 is divisible by 3 (but not 5)

5490 is divisible by 3

7290 is divisible by 3

15780

43695

===============

So your answer is

7295

I think that's the only one divisible by 5 but not 3.

===============

There's a quick way to divide by 3. Just add the digits. If the sum is divisible by 3 then the whole number is divisible by 3

For example 285

2 + 8 + 5 = 15.

15 is divisible by 3 so 285 is divisible by 3.

==================

7295 = 7 + 2 + 9 +5.  Anything adding up to 9 you can cast out.

7 + 2 = 9 Cast it out

9 = 9       Cast it out

5  is not divisible by 3, so 7295 is not divisible by 3

Using the Equation, predict how much the Temperature change will be in 20 years since 2000.

Answers

Answer:

0.82° C

Step-by-step explanation:

To predict how much change the temperature will be in 20 years time since 2000, simply substitute x = 20 into the given equation, [tex] y = 0.52 + 0.015x [/tex]:

[tex] y = 0.52 + 0.015(20) [/tex]

[tex] y = 0.52 + 0.3 [/tex]

[tex] y = 0.82 [/tex]

✅The temperature change would be 0.82° C.

What is the equation of a line that has a slope of 2/5 and passes through the
point (-5,5)? *

Answers

Answer:

y = 2/5x + 7

Step-by-step explanation:

substitute 2/5 in for m and (-5,5) in for (x,y) respectively to find the y intercept

y=mx+b

5 = 2/5(-5) + b

5 = -2 + b

add 2 to both sides to solve for b (y intercept)

b = 7

therefore the equation for the line will be...

y = 2/5x + 7
