Answer:

- 2x³

Step-by-step explanation:

f(x) - g(x)

= [tex]x^{\frac{1}{2} }[/tex] - x - (2x³ - [tex]x^{\frac{1}{2} }[/tex] - x) ← distribute parenthesis by - 1

= [tex]x^{\frac{1}{2} }[/tex] - x - 2x³ + [tex]x^{\frac{1}{2} }[/tex] + x ← collect like terms )

= - 2x³

Answer:

40 trees

Step-by-step explanation:

Number of tree planted = distance between the first and last trees / distance between the 2 trees

200 / 5 = 40

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set. if you need a video Explanation https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

The value of 6P6 is 720

The expression is given as:

6P6

This is calculated using:

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

So, we have:

[tex]^6P_6 = \frac{6!}{(6 - 6)!}[/tex]

Evaluate the difference

[tex]^6P_6 = \frac{6!}{0!}[/tex]

As a general rule;

0! = 1

So, we have:

[tex]^6P_6 = 6!\\[/tex]

Expand

[tex]^6P_6 = 6 * 5 * 4 * 3 * 2 * 1[/tex]

Evaluate

[tex]^6P_6 = 720[/tex]

Hence, the value of 6P6 is 720

Answer:

slope = 1

Step-by-step explanation:

A standard linear function is

y = mx + b

where m = slope, b = initial value

Given y = x + 6

slope m = 1, b = 6

Slope of a line parallel to the given line should have the same slope, therefore slope required is m = 1.

[tex]x=60^{\circ}[/tex]

Step-by-step explanation:

The angle formed by [tex]48+x[/tex] and the angle marked as [tex]72^{\circ}[/tex] are co-interior angles and therefore must be supplementary (add up to 180 degrees).

Therefore, we have:

Step-by-step explanation:

Area of a triangle = 1/2 base x height

Area of a rectangle = length x breadth

The triangle has 4km and 8km

1/2 x 8 x 4 = 32÷ 2 = 16km². area of a triangle

7km x 9km = 63 km²

The surface area is basically everything joined together making it

area of a triangle x area of a rectangle = 16km² x 63km² = 1,008km².

Complete question:

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm

Answer:

B. 16 cm

Step-by-step explanation:

Given;

two lengths of the triangle as 15 cm and 4 cm

The length of the third side of the triangle must be less than the sum of the two given sides.

Length of third side < 15 cm + 4 cm

Length of third side < 19 cm

The only option less than 19 cm is B. 16 cm

Therefore, the correct option is B. 16 cm

Answer:

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer:

x = number of tins filled in 1 minutes = 5 tins

y = number of tins filled in 60 minutes = 288 tins

It will take 5 hours to fill 1440 tins

Step-by-step explanation:

Number of tins filled : time taken = 24 : 5

Let

x = number of tins filled in 1 minutes

Number of tins filled : time taken = x : 1

Equate both ratios

24 : 5 = x : 1

24/5 = x/1

Cross product

24 * 1 = 5 * x

24 = 5x

x = 24/5

x = 4.8

To the nearest whole number,

x = 5

x = number of tins filled in 1 minutes = 5 tins

(B) 1 hour?

1 hour = 60 minutes

Number of tins filled : time taken = 24 : 5

Let y = number of tins filled in 60 minutes

Number of tins filled : time taken = y : 60

Equate both ratios

24 : 5 = y : 60

24/5 = y/60

Cross product

24 * 60 = 5 * y

1440 = 5y

y = 1,440/5

y = 288 tins

y = number of tins filled in 60 minutes = 288 tins

C. How many hours will it take to fill 1440 tins?​

Let

z = time taken to fill 1,440 tins

Number of tins filled : time taken = 24 : 5

Number of tins filled : time taken = 1440 : z

24 : 5 = 1440 : z

24/5 = 1440/z

24 * z = 5 * 1440

24z = 7,200

z = 7,200/24

z = 300 minutes

300 minutes = 300/60

= 5 hours

z = 5 hours

It will take 5 hours to fill 1440 tins

Answer:

Volume of the cone: 32π cubed unit

Step-by-step explanation:

Volume of cone: V=1/3hπr²

1/3 x 6 x π x 4^2 = 32π

Answer:

The volume of a cone is 100.53. If you want to round it to the nearest one. It's 101.

Step-by-step explanation:

To find the volume. Use the equation V=3.14r^2 h/3

r=4 and h=6 so the equation is V=3.14(4^2) 6/3

V=50.24(6) = 100.53

Answer:

x = 8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos 60 = adj side/ hypotenuse

cos 60 = 4/x

x cos 60 = 4

x = 4 / cos 60

x = 4 / .5

x = 8

Answer:

x = 8 cm

Step-by-step explanation:

To solve it ,given that it is a right angled triangle.

We can use trigonometry functions

cos 60° = adjacent side / hypotenuse

cos 60° = 4 cm / x

multiply each side by x

x × cos 60° = 4 cm × x / x

x cos 60° = 4 cm

divide each side by cos 60°

x × cos 60°/cos 60° = 4 cm / 60°

x = 4 cm / 0.5 . .( given :- cos 60° =0.4 )

x = 8 cm
