Answer:

(f ￮ g)(8) = - 6

Step-by-step explanation:

Evaluate g(8), then substitute the value obtained into f(n)

g(8) = 8 - 2 = 6 , then

f(6) = - 6

Answer:

-62

Step-by-step explanation:

Two functions are given to us , which are ,

[tex]\bf\implies f(n)= -n \\\\\bf\implies g(n)= n - 2 [/tex]

We need to find , ( f • g )(8) . So ,

⇒ ( f • g) = - n ( n - 2 )

⇒ ( f • g) = -n² + 2

⇒ (f • g) = 2 - n²

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

Substituting n = 8 :-

⇒ ( f • g)(n) = 2 - n²

⇒ ( f • g)(8) = 2 - 8²

⇒ (f • g)(8) = 2 - 64

⇒ ( f • g)(8) = -62 .

Step-by-step explanation

They have a congruent angle at the top of the triangle and they both have a right angle at the bottom. They share the same side, so this is ASA.

Answer:

No this would not be linear. This would be an inverse variation, and doesn't have a linear relation between two variables since there is not constant rate of change or slope.

Answer:

(a)Required relation is 393 + 2x ppm

(b)Amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm

(c)After 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm

Step-by-step explanation:

From the question it is given that :

Estimated [tex]CO_2[/tex] in atmosphere in 2012 is 393 (parts per million)ppm

[tex]CO_2[/tex] level increasing per year is 2 ppm

(a) Let y be the concentration of [tex]CO_2[/tex] in atmosphere after x years from 2012 then:

y = 393 + 2x ppm

Therefore required relation is 393 + 2x ppm

(b) amount of [tex]CO_2[/tex] in 2025 i.e.,x = 13 years after 2012 is y

y = 393 + 2 x 13 = 393+ 26 = 419 ppm

Therefore, amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm

(c) give y = 400 ppm and x be the year then

400 = 393 + 2x

2x = 7

⇒ x = 3.5 years

Therefore after 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm

Given:

Mara put down 7.5% on the purchase of her new home.

She put down $14.175.

To find:

The purchase price of the home.

Solution:

Let x be the purchase price of the home.

According to the question,

Put down = 7.5% of the purchase price of the home.

[tex]14.175=\dfrac{7.5}{100}\times x[/tex]

[tex]14.175=0.075x[/tex]

Divide both sides by 0.075.

[tex]\dfrac{14.175}{0.075}=x[/tex]

[tex]189=x[/tex]

Therefore, the purchase price of the home is $189.

Answer:

206 miles/hour

Step-by-step explanation:

1 kilometre per hour = 0.621 mile per hour

332 km/hr to miles per hour

= 332 km/hr × 0.621 miles per hour

= 206.295 miles per hour

Approximately to the nearest whole number

= 206 miles per hour

Badminton world record smash speed in miles is 260.17 mile per hour.

Given that;

Answer:

Step-by-step explanation:

4x + 4 - 3

= 4x + 1

Yes they both are equivalent because the algebraic expression is same

Step-by-step explanation:

150 minutes = 2.5 hours.

2.5 hours * (70 miles/hr) = 175 miles.

2 hours * (81 miles/hr) = 162 miles

Total distance = 175 + 162 = 337 miles.

Hence Michael drove 337 miles in total.

Answer:

The art gallery is 2 city blocks from the car wash

Step-by-step explanation:

Let us solve the question

∵ The art gallery is located at the point (13, -3)

∴ x1 = 13 and y1 = -3

∵ A car wash is located at (13, -5)

∴ x2 = 13 and y2 = -5

∵ x1 = x2 = 13

→ That means the gallery and the car wash located vertically over each other

∴ The distance between them = Iy2 - y1I

∵ y1 = -3 and y2 = -5

∴ The distance between them = I-5 - (-3)I

∴ The distance between them = I-5 + 3I

∴ The distance between them = I-2I

→ Remember the absolute value cancel the negative sign

∴ The distance between them = 2 units

∵ Each unit on the map is a city​ block

∵ The distance between them is 2 units

→ That means the vertical distance between them is 2 city blocks

∴ The art gallery is 2 city blocks from the car wash

Step-by-step explanation:

The probability of getting five quadrilateral with four congruent sides is,

⇒ 1 / 3

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A six sided die is rolled then a quadrilateral is chosen at random parallelogram ,rhombus, rectangle, square and trapezoid.

Hence, Total number of outcomes = 6

And, We know that;

Square and Rhombus have four congruent sides.

Hence, Number of possible outcomes = 2

Thus,  The probability of getting five quadrilateral with four congruent sides is,

⇒ 2 / 6

⇒ 1 / 3

Answer: -5, 5, 9

Step-by-step explanation: Range means y values.

Answer:

ASA

Step-by-step explanation:

If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of the other triangle, then the triangles are congruent.

The included side is the side between the vertices of the 2 triangles.

Here

∠ S = ∠ W ( 1 angle )

∠ R = ∠ X ( 2 angles )

RS = XW ( side between the 2 angles )

Thus the 2 triangles are congruent by the ASA postulate

The percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that scientists give two different treatments to people who have the flu and determine if their health improved. The results of the test are in the two-way table.

The percentage of people receiving treatment 1 had improved health is calculated as,

Percentage = 23 / ( 23 + 25 )

Percentage = 0.48 x 100 = 48%

The percentage of people receiving treatment 2 had improved health is calculated as,

Percentage = 25 / ( 23 + 25 )

Percentage = 0.52 x 100 = 52%

Therefore, the percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.

Answer:

DE = 15 cm, AB = 6 cm

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal.

(a)

[tex]\frac{DE}{BC}[/tex] = [tex]\frac{CE}{AC}[/tex] , substitute values

[tex]\frac{DE}{5}[/tex] = [tex]\frac{24}{8}[/tex] = 3 ( multiply both sides by 5 to clear the fraction )

DE = 15 cm

(b)

[tex]\frac{AB}{CD}[/tex] = [tex]\frac{AC}{CE}[/tex] , substitute values

[tex]\frac{AB}{18}[/tex] = [tex]\frac{8}{24}[/tex] ( cross- multiply )

24AB = 144 ( divide both sides by 24 )

AB = 6 cm
