A figure is translated using the mapping (x, y) → (x + a, y + b). If the value of a is negative and the value of b is negative,
MAXImum [283]

The translation is The figure moves left and down.

Option:B.

<u>Step-by-step explanation:</u>

The given coordinate  (x,y) is mapped and it gets translated using mapping (x+a,y+b).

Also, we are given with information that the value of a and also value of b is negative (-a,-b).

⇒the mapping coordinate = (x+(-a),y+(-b)).

The mapping coordinate = ( x-a, y-b).

The coordinate points will be decreasing in x and y axis. So it will move towards the left and downside of the graph.

For example,

Consider that a= -3 and b= -2.

∴The translating coordinate will be (x-3,y-2).

Choose a coordinate point ( 2,2) initially.

Substitute the x,y coordinate in the translating coordinate.

⇒ (x-3,y-2) = (2-3,2-2).

=(-1,0).

After translation the points will be (-1,0).

∴The figure will move towards left and downwards.

Given: f(a)= a³ +a and g(a) = a -1 Find: (fog)(a)​
Anvisha [2.4K]

Answer:

(fog)(a)​ = a³ - 3a² + 4a - 2

           = (a - 1)×(a² - 2a + 2)

Step-by-step explanation:

<u><em>Given</em></u> :

g(a) = a -1 

f(a)= a³ +a

…………………………

(fog)(a)​ = f(g(a)​))

           = g(a)³ + g(a)

           = (a - 1)³ + (a - 1)

           = (a³ - 3a² + 3a - 1) + (a - 1)

           = a³ - 3a² + 3a - 1 + a - 1

           = a³ - 3a² + 3a + a - 1 - 1

           = a³ - 3a² + 4a - 2

<u><em>Second method</em></u> :

(fog)(a)​ = f(g(a)​))

           = f(a - 1)

           = (a - 1)³ + (a - 1)

           = (a - 1)×[(a - 1)² + 1]

           = (a - 1)×[a² - 2a + 1 + 1]

           = (a - 1)×(a² - 2a + 2)

the length of a rectangle is 3 cm longer than it’d width. if the perimeter of the rectangle is 38, find it’s area.
lora16 [44]

Answer:

88 cm²

Step-by-step explanation:

w = x

l = x + 3

P = 38

We know that P=2l+2w, so we substitute known values:

P=2l+2w\\38=2(x+3)+{2(x)}\\38=2x+6+2x\\38=4x+6\\32=4x\\8=x

Therefore, we know that the width (x) is 8 cm and the length (x + 3) is 8 + 3 = 11 cm. To verify, we can check that the perimeter equals 38:

8 + 11 + 8 + 11 = 38. <em>Check.</em>

Thus, the area of the rectangle is:

A=l\times{w}\\A=11\times{8}\\A=88

Therefore, the area is 88 cm².

slega [8]

Answer:

52⁰

Step-by-step explanation:

Cos x⁰ = adjacent/hypotenus

Cos x⁰ = 8/13

Cos x⁰ = 0.615

x⁰ = cos^-1 (0.615)

x⁰ = 52⁰
