dont know how to do this so can someone help me?

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:

mAngle A= 132 degrees

Step-by-step explanation:

a = 5x-18. b= 3x+42

a=b because they are alternate interior

5x-18=3x+42

combine like terms

SUbtract 3x from both sides and add 18 to both sides

2x=60

divide by 2

x = 30

Now plug in 30

5(30)=150

150-18=132

Explanation:

If  

x

varies directly with

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

In this case,

Or, intuitively, if

and

when

, we can conclude that

Answer:

Circumference = 2pi(radius)

C = 2(pi)(9.5)

C = 19pi

The answer is 19pi.

Let me know if this helps!

Answer:

The circumference is 59.6903

Step-by-step explanation:

In order to find the circumference, use the equation C=2πr

Radius is essentially half of the diameter, so 9.5 is our radius

C=2π(9.5)

C≈59.6903

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

Answer:

Step-by-step explanation:

Pythagorean Theorem

(AB)² = 5.6² + 3.9² = 46.57

radius r = (√46.57)/2 cm

area = πr² = π46.57/4 ≈ 36.5759925 cm l²

Step-by-step explanation:

Supplementary angles = 180º (theorem)

Set <ABD + <DBC = 180º

2x + (x+24) = 180º

add like terms = 3x+24=180

3x=156

x = 52

now plug in x for both angles

<ABD = 2(52) = 104

<DBC = 52+24 = 76

14.

complementary angles = 90º (theorem)

set <EFG + <GFH = 90º

y-32 + y = 90

2y - 32 = 90 : combine like terms

2y = 122

y = 61

now plug in y for both angles

<EFG = 61-32 = 29

<GFH = 61

15.

Vertical angles are equal to each other (theorem)

<PQR = <TRS

38 = 5w-7

45 = 5w

w = 9

plug into <TRS

<TRS = 5(9) - 7 = 38

(Also since you know that <PRQ is 38 and that the measure has to be the same for both angles, it can be assumed without algebra that <TRS would be 38º)

Answer:

$42.50

Step-by-step explanation:

250*0.17=42.5

cause %17 in decimal form is 0.17

Answer:

250 decreased by - 17% = $207.50

Explanation

Discount = Original Price x Discount %/100

Discount = 250 × 17/100

Discount = 250 x 0.17

You save = $42.50

Final Price = Original Price - Discount

Final Price = 250 - 42.5

Final Price = $207.50

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].
