well, the opening price was "x", which oddly enough is the 100%, however during the trading of the day the company gained 3.5%, so that'd be 100% + 3.5% = 103.5%, and we know that that is 16.56, so

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 16.56&103.5 \end{array}\implies \cfrac{x}{16.56}=\cfrac{100}{103.5}\implies 103.5x=1656 \\\\\\ x=\cfrac{1656}{103.5}\implies x=16[/tex]

Answer:

y = -2x -1

Step-by-step explanation:

y-5=-2(x+3)

Distribute -2 × x and -2 × 3

y - 5 = -2x -6

y + 5 = -2x -6

y = -2x - 1

To solve the exponential equation follow all the steps given below.

Therefore,

The expression is equivalent to;

[tex]\rm =\dfrac{(5^2)^{-3}\times 5^4}{5^{-4}}\\\\=\rm \dfrac{(5)^{-6}\times 5^4}{5^{-4}}\\\\=\rm \dfrac{(5)^{-6+4}}{5^{-4}}\\\\=\rm \dfrac{5^{-2}}{5^{-4}}\\\\=5^{-2+4}\\\\=5^2[/tex]

I've attached some theories related to angles have a look at it

Angle y and angle KJF are co-interior angles so they add up to 180°

132 + y = 180

y = 180 – 132

y = 48

y + z = 143 ( alternate angles )

48 + z = 143

z = 143 – 48

x=1 and x=4 are real value or values of x satisfy the equation x−2=√x

Two or more expressions with an Equal sign is called as Equation.

Given,

Equation is x−2=√x

We need to find for which values of x satisfy the equation.

x−2=√x

Take square on both the sides

(x-2)²=√x²

We know the algebraic identity

(a-b)²=a²+b²-2ab

(x-2)²=√x²

x²+2²-2(2)x=x

x²+4-4x=x

x²+4-4x-x=0

x²-5x+4=0

x²-4x-x+4=0

x(x-4)-(x-4)=0

(x-1)(x-4)=0

x-1=0

For the expression 5.6j - 0.12 = 4 + 1.1j, the value of variable j is 0.92.

The operations of addition, subtraction, multiplication, and division do not change the truth value of any equation is called the property of equality.

The given expression is 5.6j - 0.12 = 4 + 1.1j.

To solve the above expression, we will use the following steps.

Step 1:

By the subtraction property of equality, subtract 1.1j on both sides. We get the expression,

[tex]5.6j - 0.12 -1.1j = 4 + 1.1 j - 1.1 j[/tex]

[tex]4.5 j -0.12 = 4[/tex]

Step 2:

By the addition property of equality, add 0.12 on both sides. We get the expression,

[tex]4.5j -0.12 + 0.12 = 4 + 0.12[/tex]

[tex]4.5 j = 4.12[/tex]

Step 3:

By the division property of equality, divide the above expression by 4.5. We get the expression,

[tex]\dfrac {4.5j}{4.5 }= \dfrac {4.12}{4.5}[/tex]

[tex]j = \dfrac {4.12}{4.5}[/tex]

[tex]j = 0.92[/tex]

Hence we can conclude that the value of variable j is 0.92.

Answer:

(7, -3)

Step-by-step explanation:

If M is the midpoint you can use the same translation from A to M as M to B.

The movement from A to M is 5 units up and 3 units left, or (x+5, y-3). If we do the same movement to point M (Which is (2) +5, (0) -3) we will get (7, -3).

Answer:

the coordinates of B is B(7,-3)

Step-by-step explanation:

Solution,

Here, M(2,0) is the midpoint of a line segment joining the points A(-3,3)

and B(a,b)

Let,

(x,y)=(2,0)

(x1,y1)=(-3,3)

(x2,y2)=(a,b)

Now,

Using midpoint formula

The area of a circle with a radius of 5 cm is 50.272 [tex]cm^2[/tex] bigger than a circle with a radius of 3 cm.

Given the following data:

Mathematically, the area of a circle is given by the formula:

[tex]Area = \pi r^2[/tex]

Where:

For circle A:

[tex]Area = 3.142 \times 5^2\\\\Area = 3.142 \times 25[/tex]

Area = 78.55 [tex]cm^2[/tex].

For circle A:

[tex]Area = 3.142 \times 3^2\\\\Area = 3.142 \times 9[/tex]

Area = 28.278 [tex]cm^2[/tex].

Now, we can calculate the difference:

Difference = [tex]78.55-28.278[/tex]

Difference = 50.272 [tex]cm^2[/tex].

Step-by-step explanation: EDGE 2022 I GOT 100%

Answer:

(i) 64°

(ii) 26°

Step-by-step explanation:

Answer:

(i) m<ADB = 64°

(ii) m<ACD = 26°

Step-by-step explanation:

I use this to mean the measure of angle ADC: m<ADC

(i)

m<BEC = 52°

<DEA and <BEC are vertical angles, so they are congruent.

m<DEA = m<BEC = 52°

Polygon ABCD is a rectangle. When the diagonals, AC and BD, of a rectangle are drawn, 4 triangles are formed. Each two opposite triangles are congruent, and all 4 triangles are isosceles.

Triangle ADE is an isosceles triangle with congruent sides ED and EA. That makes opposite angles ADB and DAC congruent. Also the sum of the measures of the angles of a triangle is 180°.

m<ADB + m<DAC + m<DEA = 180°

m<ADB = m<DAC; m<DEA = 52°

2m<ADB + 52° = 180°

2m<ADB = 128°

m<ADB = 64°

(ii)

Angles DEC and BEC form a linear pair. That means the angles are supplementary, and the sum of their measures is 180°.

m<DEC + m<BEC = 180°

m<DEC + 52° = 180°

m<DEC = 128°

Triangle DEC is an isosceles triangle with congruent sides ED and EC. That makes opposite angles ACD and BDC congruent.

m<ACD + m<BDC + m<DEC = 180°

2m<ACD + 128° = 180°

2m<ACD = 52°

m<ACD = 26°

Answer:

Constant of proportionality: [tex]\frac{1}{3}[/tex]

Equation: [tex]y=\frac{1}{3}x[/tex]

Step-by-step explanation:

The constant of proportionality is the ratio between y and x, according to the following formula

constant of proportionality = k = y/x

Take the given pairs and replace the data.

1.

[tex]k=\frac{\frac{2}{3}}{2}[/tex]

[tex]k = \frac{1}{3}[/tex]

2.

[tex]k = \frac{1}{3}[/tex]

3.

[tex]k=\frac{\frac{10}{3}}{10}[/tex]

[tex]k = \frac{1}{3}[/tex]

4.

[tex]k = \frac{4}{12}[/tex]

[tex]k = \frac{1}{3}[/tex]

As you can see, the constant is the same for all the pairs.

constant of proportionality = [tex]\frac{1}{3}[/tex]

Now, in order to know the equation make a graph of the given data.

The graph is in the picture

Since it is a line, use the equation of the line in point slope form

[tex]y- { y }_{ 1 } = m \left( x- { x }_{ 1 } \right)[/tex]

where (x1, y1) = any pair of the data

m = slope = constant of proportionality

Replace the data in the equation

[tex]y-1 = \dfrac{ 1 }{ 3 } \left( x-3 \right)[/tex]

Use the distributive property to multiply [tex]\frac{1}{3}[/tex] by x - 3

[tex]y-1=\frac{1}{3}x-1[/tex]

Add 1 to both sides

[tex]y = \dfrac{ 1 }{ 3 } x-1+1[/tex]

Add −1 and 1 to get 0

[tex]y=\frac{1}{3}x[/tex]

or

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