2. State the commutative property of multiplication using the variables a and b​

Answers

Answer 1

Answer:

a x b = ab     b x a = ab

Step-by-step explanation:

3x4= 12

4x3= 12

The commutative property states that the interchanging of elements will not affect the answer

Answer 2

Answer:

a × b = b × a

Step-by-step explanation:

Communatative Property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer

To help you understand this, let's try switching out the variables for numbers.

Let's say a=3 and b=2

We know that 3 times 2 is 6. By using the Communatative Property we also know that 2 times 3 is 6 (because if we switch the position of the numbers 3 and 2, we would still get the answer 6)  So....

3 × 2 = 2 × 3 which would be the same as

a × b = b × a

Coach Jump is standing on a platform watching the football team practice. If the platform is 12 feet high and the quarterback is standing 23 feet from the base of the platform, find the angle of depression from Coach Jump to the quarterback. Round to the nearest degree.

Answers

Answer:

62 degrees.

Step-by-step explanation:

What you will have here is a right triangle. For the vertical put 12 ft and for the horizontal put 23 ft. You are trying to find the angle between the verticle and hypotenuse. This is what tangent is used for since you know the opposite and you know the adjacent lengths.

But since you are trying to find the angle you need to do an inverse tangent (also called arctangent)

ArctanФ = Adj/opposite

ArctanФ = 12/23 = 27.47 degrees. Rounded to the nearest degree is 27 degrees, if it wants rounded up its 28 degrees.

The angle of depression from Coach Jump to the quarterback is 27.6°.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

In this diagram,

C represents Coach Jump,

B represents the base of the platform,

θ represents the angle of depression from Coach Jump to the quarterback.

Now,

We want to find θ.

We can use the tangent function,

So,

tan Ф = 12/23

Ф = [tex]tan^{-1}[/tex] 12/23

Ф = 27.55°.

Thus,

The angle of depression from Coach Jump to the quarterback is 27.6°.

Answer:

Step-by-step explanation:

I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.

So we have [tex]\frac{3}{5} x[/tex] = 21

When it comes to equations with a variable, our goal is to isolate the variable, so let's start.

[tex]\frac{3}{5} x[/tex] = 21

1. Combine multiplied terms into a single fraction :

[tex]\frac{3x}{5}[/tex] = 21

2. Multiply both sides by the denominator :

5 * 3/5 = 3

5 * 21 = 105

3x = 105

3. Divide both sides by 3 :

[tex]\frac{3x}{3} = \frac{105}{3 }[/tex]

x = 35

If AB=9 and AD=27, find AC

Answers

Answer:

AC = 3

Step-by-step explanation:

Based on tangent and secant theorem, thus:

AB² = AC × (AC + CD)

AB = 9

AD = AC + CD = 27

Plug in the values

9² = AC × (27)

81 = AC × 27

Divide both sides by 27

81/27 = AC

3 = AC

AC = 3

As we know density is defined as mass per unit volume so here

Density is recorded in units of grams per milliliter

So Now

Mass (m) = 100 g

Volume (V) = 50 ml

Density (d)

= m/v

Answer:

[tex]\frac{9}{5}[/tex] or [tex]1\frac{4}{5}[/tex]

Step-by-step explanation:

First add 1/5 from both sides to get 2/3x > 6/5. This can then be simplified to x > 18/10. 18/10 is the same as 9/5. And 9/5 is also 1 4/5.

Hope it helps!

Answer:

[tex]x>\frac{9}{5}[/tex]

Step-by-step explanation:

To reduce any confusion later on in the problem the first step should getting the fractions to have an equal denominator, this can be done by finding the LCF, or Least Common Factor.

In this case the least common factor is [tex]15[/tex], [tex]3[/tex] × [tex]5 = 15[/tex], and [tex]5[/tex] × [tex]3 = 15[/tex]; whatever you do to the denominator has to be done to the numerator

[tex]\frac{2}{3}[/tex] × [tex]\frac{5}{5} = \frac{10}{15}[/tex]            [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{3} =\frac{3}{15}[/tex]

Now that the denominators are equal, lets input the values into the original equation:

[tex]\frac{10}{15} x-\frac{3}{15} >1[/tex]

add [tex]\frac{3}{15}[/tex]  to both sides, to isolate the variable

[tex]\frac{10}{15}x > 1\frac{3}{15}[/tex]  [tex]or \frac{18}{15}[/tex]  

divide

both sides by [tex]\frac{10}{15}[/tex], when you divide fractions you multiply  by the reciprocal of the divisor, then you multiply the numerators by the numerators and the denominators by the denominators. [tex]18[/tex] × [tex]15[/tex][tex]=270[/tex] , [tex]15[/tex] × [tex]10=150[/tex]

[tex]x>\frac{18}{15}[/tex] × [tex]\frac{15}{10}[/tex] ⇒  [tex]x>\frac{270}{150}[/tex]

[tex]270[/tex] and [tex]150[/tex] have a GCF, or Greatest Common Factor of [tex]30[/tex] which simplifies the answer to:

[tex]x>\frac{9}{5}[/tex]

What is Balanced?

In science, if an object is still, we say it is balanced. An object is in an equilibrium state when it is balanced. Any forces acting on the object are counterbalanced by forces moving the other way. The average location of the gravitational pull on an object is known as the centre of gravity.

We have the figure.

On right side there are total 8 weights.

and, on left there are total 3 weights.

So, the difference of blocks on

= 8- 3

if you tell correctly I will give brainlist​

Answers

Given:

One of the legs of a right triangle is 9 cm.

The area of the triangle is 225 cm².

To find:

The length of the other leg.

Solution:

The area of a triangle is

[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]

The area of a right triangle is

[tex]Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)[/tex]

Let x be the length of other leg.

[tex]225=\dfrac{1}{2}\times (9)\times (x)[/tex]

[tex]2\times 225=9x[/tex]

[tex]\dfrac{450}{9}=x[/tex]

[tex]50=x[/tex]

Therefore, the length of the other leg is 50 cm.

Find the equation of the linear function represented by the table below in slope-
intercept form.

Answers

Answer:

f(x) = 5x - 5

Step-by-step explanation:

Let the equation of the linear function is,

f(x) = mx + b

Here, m = Slope of the graph

b = y-intercept

Slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]

From the table attached,

Slope of the line passing through (2, 5) and (6, 25) will be,

m = [tex]\frac{25-5}{6-2}[/tex]

m = 5

Equation of the linear function will be,

f(x) = 5x + b

Since, a point (10, 45) lies on the function,

45 = 5(10) + b

b = 45 - 50

b = -5

Equation of the linear function will be,

f(x) = 5x - 5
