Answer:

Addition Property of Equality

Step-by-step explanation:

Addition Property of Equality.

The addition property of equality justifies the work done in Line 3. This is because it essentially states that if you add something to one side of an equation, you must add it to the other side as well. In this case, we are adding 22 to both sides of the equation, therefore we are making use of the Addition Property of Equality.

Answer:

40/10  [4 meters/sec]

Step-by-step explanation:

Watch for what the units are telling us.  The number that is being requested  

is speed in units of meters/sec.  We are given 40 meters and 10 seconds.  If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

Answer:

When l = 4m , breadth is 8m

When l = 8m , breadth is 4m .

Step-by-step explanation:

Here it is given that the area of a rectangular patch is 32m² . If we assume length to be l and breadth to be b , then ;

[tex]\longrightarrow Area_{rectangle}=length\times breadth\\ [/tex]

[tex]\longrightarrow 32m^2 = lb \dots (i) [/tex]

Again , it's given that the perimeter is 24m .We know that perimeter of a rectangle is ,

[tex]\longrightarrow Perimeter = 2(l+b)\\ [/tex]

[tex]\longrightarrow 24 = 2( l +b)\\ [/tex]

[tex]\longrightarrow l + b = 12\dots (ii) [/tex]

From equation (i) and (ii) , we have ;

[tex]\longrightarrow l + \dfrac{32}{l}=12\\\\\longrightarrow \dfrac{l^2+32}{12}=1\\\\\longrightarrow l^2+32=12l \\\\\longrightarrow l^2-12l +32=0\\\\\longrightarrow l^2-4l -8l +32=0 \\\\\longrightarrow l( l -4) -8(l-4)=0\\\\\longrightarrow(l-4)(l-8)=0 \\\\\longrightarrow \underline{\underline{ l = 4,8}} [/tex]

Therefore , we can find breadth as,

[tex]\longrightarrow l + b =12\\\\\longrightarrow b = 12 - l \\\\\longrightarrow b = 12-8, 12-4\\\\\longrightarrow \underline{\underline{b = 4,8}}[/tex]

Answer:

11 is the answer.

Step-by-step explanation:

11 and 23 are the answers.

Step-by-step explanation:

Multiple of 2 increase 1 =

[tex]3,5,7,9,11,13,15,17...[/tex]

Multiple of 3 increase 2 =

[tex]5,8,11,14,17...[/tex]

There are more numbers having this property such as 23.

[tex]23 \div 2 = 11...1[/tex]

[tex]23 \div 3 = 7...2[/tex]

[tex]23 \div 4 = 5...3[/tex]

The polynomial  [tex]3x^5 + 7x^6 + 11x^7 - 12x - 10[/tex] is in standard form if the exponents are arranged in decreasing order.

Polynomial is an algebraic expression with one or more terms. For example :[tex]2x^3+6x^4+x^2+x+2[/tex]. In this example and in your exercise the exponents of the terms are not arranged in order.

Um polynomial is in Standard Form when the exponents of the terms are in decreasing order. See more details below.

[tex]2x^3+6x^4+x^2+x+2[/tex]is not in standard form because the exponents are not written in decreasing order.

[tex]6x^4+2x^3++x^2+x+2[/tex] is in standard form because the exponents are written in decreasing order.

Therefore, the given polynomial will be in standard form if yours exponents are arranged in decreasing order.

Answer:

c ≈ 70.7

Step-by-step explanation:

Solve using the Pythagorean theorem:

-Chetan K

Step-by-step explanation:

the distance between 2 points is the Hypotenuse of a right-angled triangle with the legs being the x coordinate difference and the y coordinate difference.

so, Pythagoras applies.

c² = a² + b²

distance² = (2 - -7)² + (11 - 9)² = 9² + 2² = 81 + 4 = 85

distance = sqrt(85) = 9.219544457... ≈ 9.2

The distance between the points A(2,11) and B(−7,9) is d = √85.

There are two points (a, b) and (c, d) then the distance between two points is

d= √(c -a)² + (d-b)²

We have the points A(2, 11) and B(-7, 9).

Using the Distance Formula

d = √(-7-2)² + (9-11)²

d= √(-9)² + (-2)²

d= √81 + 4

d = √85

Thus, the distance between points is √85 unit.

  (b) 3°

  (c) 238°

Step-by-step explanation:

Bearings are measured clockwise from north. The triangle described is illustrated in the attachment.

The bearing of P from R is 180° different from the bearing of R from P it will be ...

  135° +180° = 315° . . . . bearing of P from R

__

The bearing of Q from R is 48° more than the bearing of P from R, so is ...

  315° +48° = 363°, or 3° . . . . bearing of Q from R

__

The angle QPR has a value that makes the sum of angles in the triangle equal to 180°. It is ...

  180° -48° -55° = 77°

The bearing of Q from P is 77° less than the bearing of R from P, so is ...

  135° -77° = 58°

As above, the reverse bearing from Q to P is ...

  58° +180° = 238° . . . . bearing of P from Q

Answer:

B

Step-by-step explanation:

Answer: f(x) = 3x^(2)-2x+1

f(x) = 3x^(2)-2x+1 = y-intercept (0, 1).

g(x) = -10x^(2)+50x = y-intercept (0, 0).

As we see, the first equation (f(x) = 3x^(2)-2x+1) has a y-intercept of (0, 1), while the other equation (g(x) = -10x^(2)+50x) has a y-intercept of (0, 0). This means that the quadratic equation that has the greatest y-intercept is f(x) = 3x^(2)-2x+1, which is (0, 1).

Answer:

x=3.42

Step-by-step explanation:

[tex] \sin(20) = \frac{x}{10} [/tex]

[tex]x = 10 \sin(20) = 3.42[/tex]

Answer:

x = 3.420 (to the nearest hundredth)

Step-by-step explanation:

Trig ratios:

sin(x) = O/H

cos(x) = A/H

tan(x) = O/A

where x is the angle, O = side opposite the angle, A = side adjacent to the angle, H = hypotenuse

We have been given:

angle = 20°

opposite side to angle = x

hypotenuse = 10

Therefore, we should use sin(x) = O/H

Substituting the above values into the trig ratio:

⇒  sin(20) = x/10

⇒  x = 10 sin(20)

⇒  x = 3.420 (to the nearest hundredth)
