Step-by-step explanation:

Answer:

£12

Step-by-step explanation:

It's asking us to find the 30% of the 40 and to do this we multiply 40 by 30 then divide it by 100

40 × 30 ÷ 100 = 12

Answer:

[tex]y=x^2-8x+25[/tex]

Step-by-step explanation:

To answer this question, we will work backwards.

We know that a factor is 4+3i. This means that:

[tex](x-(4+3i))=0[/tex]

Hence, we will eliminate the imaginary and convert this into standard form.

First, distribute the negative:

[tex]x-4-3i=0[/tex]

Add 3i to both sides:

[tex]x-4=3i[/tex]

Square both sides:

[tex](x-4)^2=(3i)^2[/tex]

Expand:

[tex]x^2-8x+16=9(-1)=-9[/tex]

Add 9 to both sides:

[tex]x^2-8x+25=0[/tex]

Hence, our quadratic equation is:

[tex]y=x^2-8x+25[/tex]

Notes:

We will get the same equation if we use (4-3i). This is because we square the (3i) regardless of its sign, making it positive.

Answer:

R0

Step-by-step explanation:

Given the following data;

Principal, P = R625

Time, t = 1 year

Rate, r = 10% = 10/100 = 0.1

To find compound interest;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Substituting into the equation, we have;

[tex] A = 625(1 + \frac{10}{100})^{1}[/tex]

[tex] A = 625(1 + 0.1)[/tex]

[tex] A = 625(1.1)[/tex]

A = 687.5

Therefore, C.I = A - P

C.I = 687.5 - 625

C.I = 62.5

To find the simple interest;

[tex] S.I = \frac {PRT}{100} [/tex]

[tex] S.I = \frac {625 *10*1}{100} [/tex]

[tex] S.I = \frac {6250}{100} [/tex]

S.I = 62.5

Now to find the difference;

Difference = C.I - S.I

Difference = 62.5 - 62.5

Difference = R0

59.9%

Sorry I don’t have time to explain in the middle of an exam

The rate of growth needs to be 59.9%.

The formula used to determine the future value of an investment when interest is compounded continuously is:

FV =  A x [tex]e^{r}[/tex] x N

$320,000 = $16,000 x [tex]e^{r}[/tex] x 5

Divide both sides by $16,000

20 = 5[tex]e^{r}[/tex]

Take the In of both sides

In(20) = 5r

Divide both sides by 5

r = 59.9%

Answer:

<1=83

<2=97

<3= 83 (given)

<4=97

<5=83

<6=97

<7=83

<8=97

Step-by-step explanation:

They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.

Answer:

If  [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at  [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].

Step-by-step explanation:

Let [tex]e^{x\cdot y}-y^{2} = e-4[/tex]. At first we determine the first derivative of the function by implicit differentiation:

[tex]e^{x\cdot y}\cdot \left(y+x\cdot \frac{dy}{dx} \right)-2\cdot y \cdot \frac{dy}{dx} = 0[/tex]

[tex]y\cdot e^{x\cdot y}+x\cdot e^{x\cdot y}\cdot \frac{dy}{dx} -2\cdot y\cdot \frac{dy}{dx} = 0[/tex]

[tex]y\cdot e^{x\cdot y}= (2\cdot y -x\cdot e^{x\cdot y})\cdot \frac{dy}{dx}[/tex]

[tex]\frac{dy}{dx} = \frac{y\cdot e^{x\cdot y}}{2\cdot y - x\cdot e^{x\cdot y}}[/tex]

If we know that [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], then the computed value of the function is:

[tex]\frac{dy}{dx} = \frac{(2)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}{2\cdot (2)-\left(\frac{1}{2} \right)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}[/tex]

[tex]\frac{dy}{dx} \approx 2.059[/tex]

If  [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at  [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].

Answer:

the number of grams of zinc contain is 78

Step-by-step explanation:

The computation of the number of grams of zinc contain is shown below:

Given that the ratio of zinc to copper is 3:16

And, the jar of the chemical has 416 grams copper

So, the number of zinc grams would be

here we assume the zinc grams be x

Now the equation would be

3 ÷ 16 = x ÷ 416

Now applied the cross multiplication

16x = 416 × 3

x = (416 × 3) ÷ 16

= 78

Therefore the number of grams of zinc contain is 78

Two sides are congruent to each other.

The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

A triangle with all sides of different lengths. All angles are different, too. So no sides are equal and no angles are equal.
