Money in Alex's account after 16 years = [tex]\boxed{\bold{\color{plum}£4347.11}}[/tex]

Money invested by Alex = £3045

Percentage of compound interest per annum = 2.25%

We know that :

[tex]\tt \: \color{hotpink}A \color{plum} = P {(1 + \frac{r}{n} )}^{nt} [/tex]

In this case :

Principal = £3045

Rate = 2.25% = 0.0025

Number of times interest is compounded per year = 1

Time = 16 years

Which means :

Money Alex will have in the account after 16 years :

[tex] = \tt3045 ({1 + \frac{ 0.0025}{1} })^{16} [/tex]

[tex] \color{plum}= \tt £4347.11[/tex]

Therefore, the money in Alex's account after 16 years = £4347.11

Answer:

Al hijo mayor le corresonden 0,18 Hm²

Al segundo hijo  le corresponden 1200 m²

Al hijo menor le corresonden   6000000 cm²

Step-by-step explanation:

Al hijo mayor le corresponden 18 Dm²  la mitad de la finca

En Hm²     sn 18 /100   0,18 Hm²

Al hijo menor le corresponden 1/3 de la mitad de la finca (18 Dm²)

es decir  1/3 * 18 Dm²      6  Dm²    

en m²    serán      6 * 100 = 600 M²

y en cm²      600 * 10000 = 6000000 cm²

Al segundo hijo le corresponden 2/3 de la mitad es decir

2/3 * 18  = 12 Dm²  o     12 * 100  = 1200 m²

Answer:

[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \cos(A)=\frac{2}{5}\text{ and } \tan(A)<0[/tex]

And we want to determine the value of:

[tex]\sin(2A)[/tex]

First, since cos(A) is positive and tan(A) is negative, this means that ∠A must be in QIV.

In QIV, cosine is positive, sine is negative, and tangent is also negative.

The given ratio tells us that the adjacent side to ∠A is 2, and the hypotenuse is 5.

Then by the Pythagorean Theorem, the opposite side will be given by:

[tex](2)^2+o^2=(5)^2[/tex]

Solve for the opposide side:

[tex]o=\sqrt{5^2-2^2}=\sqrt{21}[/tex]

So, with respect to ∠A, the adjacent side is 2, the opposite side is √(21), and the hypotenuse is 5.

Using the double-angle identity, we can rewrite our original expression as:

[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]

Using the above information, substitute in values. Remember that cosine is positive and that sine is negative:

[tex]\displaystyle \sin(2A)=2\Big(-\frac{\sqrt{21}}{5}\Big)\Big(\frac{2}{5}\Big)[/tex]

Simplify. Therefore:

[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]

Answer:

sin 2A=2sin Acos A

=2×2/5×√21/5=±4√21/25

Step-by-step explanation:

cos A=2/5

B/H=2/5

corresponding value we get

B=2

H=5

by using Pythagoras law

H²=P²+B²

5²=P²+2²

P²=25-4

p=√21

now

sin A=P/H=√21/5

now

sin 2A=2sin Acos A=2×2/5×√21/5=±4√21/25

We can solve this using ration reasoning:

Explanation:

If  

x

varies directly with  

y

(written

), then doubling  

y

means doubling  

x

, so the rations of final values and initial values will be the same:

x

x

=

y

y

In this case,

x

x

18

=

12

Or, intuitively, if  

x

and  

x

when  

y

=

18

, we can conclude that

x

=

Answer:

.133

Step-by-step explanation:

1 is in the tenths place

3 is in the hundredths place and

2 is in the thousandths place

when given at what place to be rounded to the answer should reflect the numbers to the thousandth place

so look to the right 5 or more add one to the left number

5 or less leave the number in the thousandths place as is

00000.1325

Step-by-step explanation:

Since rounding numbers dealso with real numbers or figures, .1325 will be represented as 0.1325 and it deals with numbers before the decimal which we also called significant numbers. those after are not significant.

So therefore in relation to this; 0.1325 the decimal will be moved three times to the left because thousands means there zeros. the result will be 0000.1325

The option that has or contains two parabolas is  I(x)=P(x+5)−4. Learn more about the graph below.

A parabola graph is known to be a kind of graph that shoes a U-shaped curve that is often drawn for any given  quadratic function.

Note that in Mathematics, a parabola is said to be created as a result of the intersection of a right circular cone when passed by a plane surface and thus gives an symmetrical plane U-shaped curve.

Step-by-step explanation:

We get [tex]\frac{3}{4}[/tex] when we subtract [tex]\frac{4.5}{4}[/tex] from [tex]\frac{7.5}{4}[/tex].

Subtraction is a operation of taking the difference of two numbers.

According to the given question

We have a number line in which two numbers are indicated.

The one just after [tex]\frac{4}{4}[/tex] and the another one is after [tex]\frac{7}{4}[/tex].

So the number after [tex]\frac{4}{4}[/tex] is [tex]\frac{4.5}{4}[/tex] and the number after [tex]\frac{7}{4}[/tex] is [tex]\frac{7.5}{4}[/tex]

so, [tex]\frac{7.5}{4} -\frac{4.5}{4} =\frac{3}{4}[/tex]

Hence,  we get [tex]\frac{3}{4}[/tex] when we subtract [tex]\frac{4.5}{4}[/tex] from [tex]\frac{7.5}{4}[/tex].
