Answer:

see explanation

Step-by-step explanation:

(a)

Consider the denominator

To obtain 5xy from x , multiply by 5y

Thus numerator is multiplied by 5y, that is

[tex]\frac{1}{x}[/tex] = [tex]\frac{5y}{5xy}[/tex]

(b)

Consider the numerator

To obtain 5ab² from ab, multiply by 5b

Thus denominator is multiplied by 5b, that is

[tex]\frac{ab}{2c}[/tex] = [tex]\frac{5ab^2}{10bc}[/tex]

Answer:

2 + i

Step-by-step explanation:

Given

[tex]\frac{4+\sqrt{16-(4)(5)} }{2}[/tex]

= [tex]\frac{4+\sqrt{16-20} }{2}[/tex]

= [tex]\frac{4+\sqrt{-4} }{2}[/tex]

= [tex]\frac{4+2i}{2}[/tex]

= 2 + i

Step-by-step explanation:

On the graph, you can pick 2 points to find slope with slope formula:

(y2-y1)/x2-x1)

Two points we can choose from the graph are (0,0) and (1,3).

Now we plug these into our formula:

(1-0)/(3-0)

Answer:

121cm −25πcm ≈42.46cm

Step-by-step explanation:

First, calculate the area of the whole figure, including the unshaded area.

(The area of a rectangle is the length times the width.)

Next, calculate the area of the inner figure.

π×5cm×5cm=25πcm

Finally, subtract the area of the inner circle from the area of the outer rectangle.

Answer:

$150

Step-by-step explanation:

Well we know that 10% is going to equal 1/10 of 100%.

So now just multipy 15% times 10 to get the original price.

The possible values of the solutions to the equations are; (π/4, 7π/4)

We are given the equation;

sin(5x - π) = (√2)/2

Now, (√2)/2 is also expressed as 1/√2.

Thus;

sin(5x - π) = 1/√2

5x - π = sin⁻¹(1/√2)

5x - π = π/4

5x = π + π/4

5x = ⁵/₄π

Thus;

x = π/4

Now, since x < 2π, then it means it is in the fourth quadrant. Thus;

x = 7π/4

Answer:

[tex]101 * 102 = 10302[/tex]

Step-by-step explanation:

Given

[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]

Required

Find 101 * 102

[tex]101 * 102 =[/tex]

Express as a sum of 100

[tex](100 + 1) * (100 + 2)[/tex]

Compare this to [tex](x + a)(x + b)[/tex]

We have that:

[tex]x = 100[/tex]

[tex]a = 1[/tex]

[tex]b = 2[/tex]

Recall that:

[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]

Substitute 100 for x, 1 for a and 2 for b

[tex](100 + 1) * (100 + 2) = 100^2 + (1 + 2) * 100 + 1 * 2[/tex]

[tex](100 + 1) * (100 + 2) = 100^2 + 3 * 100 + 2[/tex]

[tex](100 + 1) * (100 + 2) = 10000 + 300 + 2[/tex]

[tex](100 + 1) * (100 + 2) = 10302[/tex]

Hence:

[tex]101 * 102 = 10302[/tex]

Answer:

y= -2 +490

3

Step-by-step explanation:

y=mx+b is the slope intercept form of a like where m is the slope and b is the y intercept

Answer:

y=-2/3x+490

Step-by-step explanation:

As we know the formula for slope intercept form would be y=mx+b

therefore we arrange our numbers in the following manner:

First subtract 2x from 2x so it'll be like 2x-2x and they cancel each other out so keep that in mind, now what you do on one side you have to do it on the other side as well therefore you'll putt -2x on the other side now we are left our equation as 3y=1,470-2x

Second, as we want our form to be slope intercept form I believe that y should be by it self and to do that you need to divide 3 from y, now remember that what you do on one side you have to do it on the other. So you'll divide 3 from all the numbers on the other side. Now on the other side we have 1,470-2x so we will divide 1,470/3=490 and -2x/3 now we are left with y= 490-2/3x ( i left -2/3x as that because dividing makes it a decimal and a decimal and the fraction has the same value so I just left it as a fraction)

Thirdly, sense we want our equation as a slope intercept form we will need to rearange our equation which we need to keep in mind the form which is y=mx+b so that makes it to our answer y=-2/3x+490

Answer: D.

Step-by-step explanation:

The last statement is false.

Answer:

1 is false.

Step-by-step explanation:

1. Look at the signs.

2. Look at the number itself. If you are dealing with a positive, you count up to get higher numbers. If you are dealing with a negative(a number with - at the beginning) you count up to get lower numbers.

3. Compare the decimal in the number to the decimal in the other number.

4. Look at the greater-than and less-than signs.

5. Use what you know about positive and negative numbers and decimals and apply that to the statement. If the statement makes sense, it is true. If the statement does not make sense, it is false.

Answer:

-8 and 3

Step-by-step explanation:

The asked numbers are -8 and 3.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given that, two numbers multiply to -24 and add up to -5

Let the two numbers be x and y

x+y = -5...(i)

xy = -24

x = -24/y...(ii)

Put eq (ii) in eq (i)

-24/y + y = -5

-24 + y² = -5y

y²+5y-24 = 0

Factorizing,

y = 8 and 3

Taking y = 3, put it in eq(ii)

x = -24/3

x = -8

Hence, the asked numbers are -8 and 3.

Answer:

Step-by-step explanation:

Angle addition postulate:

angle FGB = 105°

angle BGH = 54°

The measure of angle FGH.

angle FGB + angle BGH = angle FGH

By putting the respected values, we get

105° + 54° = angle FGH

or, 159° = angle FGH

The measure of angle FGH is 159° .

Answer:

80°

Step-by-step explanation:

alternate angles are equal

angles in a straight line add upto 180°

therefore angle ABC =80°

But it is alternate to the one at x.

Answer:

x = 80°

Step-by-step explanation:

∠CBD = ∠ABF  

          = 100°

(Vertically opposite angles are equal and AD and EH are parallel with CG cutting across both lines)

∠x = 180°-100°

    = 80°

(∠ABF and ∠x are consecutive interior angles as they are within two parallel lines so they add up to 180°)

Answer:

The circumference of the tree will be: 25.12 inches

Step-by-step explanation:

The radius of the tree = r = 4 inches

As the tree is sold based on the circumference of the tree.

The formula of the circumference = C = 2πr

                                                               = 2(3.14)(4)     ∵ r = 4 inches

                                                               = 25.12 inches

Therefore, the circumference of the tree will be: 25.12 inches
