Step-by-step explanation:

Answer:

F(-2) = 12

Step-by-step explanation:

F(-2) = (-2)²- 2(-2) + 4

= 4 - (-4) + 4

= 4 + 4 + 4

= 12

The required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

A quadratic function is given F(x) = x² − 2x + 4, value of the function is to be determined at x = -2.

What is a polynomial function?

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

F(x) = x² − 2x + 4
Above given function is a quadratic function,
in order to find F(-2) , we have to put x = -2 in above given function.

F( -2 ) = ( -2 )² − 2( -2 ) + 4
F( -2 ) =  4 + 4 + 4
F( -2 ) =   16

Thus, the required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

Answer: m<O = 11

Step-by-step explanation: you add angle N, O, and P to equal to 180° and when you solve that equation you get 11. Hopes this helps love u ❤️

The measure of angle O from the given triangle is 9°.

Given that, m∠N=(5x-8)°, m∠O=(x-5)° and m∠P=(6x+1)°.

We need to find the measure of angle O.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Now, m∠N+m∠O+m∠P=180°

⇒ (5x-8)°+(x-5)°+(6x+1)°=180°

⇒ 5x+x+6x-8-5+1=180

⇒ 12x-12=180

⇒ 12x=192

⇒ x=192/12

⇒ x=16

So, m∠O = 16-5=9

Therefore, the measure of angle O from the given triangle is 9°.

Answer:

[tex]\frac{\sqrt{2} }{8}[/tex]

Step-by-step explanation:

Using the exact values of the given trig functions, then

sin45° × sin30° × cos60°

= [tex]\frac{\sqrt{2} }{2}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = [tex]\frac{\sqrt{2} }{8}[/tex]

Step-by-step explanation: x = 73°

Draw PQ through E and parallel to AB, CD

Have x = ∠QED + ∠QEB

because PQ // CD => ∠QED = 50°

AB // PQ => ∠QEB + 157° = 180°

=> ∠QEB = 180 - 157 = 23°

=> x = 23° + 50° = 73°

( PQ   is in the same direction as AB and CD )

angle efd = 130

180-50=130

angle ahe =23

180-157= 23

draw a imaginary line from h to f

this will create a triangle

now angle hfc = 90

90-50=40

now angle hfe =

90 - 23 = 67

therefore ,

x =

67+40+x=180

107 + x = 180

x = 180-107

x=73

Answer:

(4,3)

Step-by-step explanation:

2y = x + 2

x - 3y = -5

Rearrange the second equation to equal y.

x - 3y = -5

x + 5 = 3y

(x+5)/3 = y

Substitute into the first equation.

2y = x +2

2[(x+5)/3] = x + 2

(2x + 10)/3 = x + 2

2x + 10 = 3(x + 2)

2x + 10 = 3x + 6

10 - 6 = 3x - 2x

4 = x

Therefore, the correct ordered pair is (4,3) since x is equal to 4.

Answer:

x = 7

Step-by-step explanation:

all triangles add up to 180

(90 from the right angle)

90 + (4x) + (5x +27) = 180

117 + 9x = 180

-117          - 117

9x = 63

x = 63/9

x = 7

Answer:

x = 7

Step-by-step explanation:

All triangles add up to 180, and (90 from the right angle)

90 + (4x) + (5x +27) = 180

117 + 9x = 180

-117          - 117

9x = 63

x = 63/9

Therefore, x = 7

Based on the data shown in the graph, how many hours will it take the shipping company to pack 180 boxes

Answer:

What graph

The time taken by the shipping company to pack 180 boxes is 15 hours.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

The given graph is the direct relation and has a constant proportion as,

Book packed/hour = 60/5 = 12

With this constant of proportionality,

For 180 boxes,

180/hour = 12

Hour = 15

Hence "It takes the shipping business 15 hours to pack 180 cartons".
