Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?​

Answers

Answer:

£3,692

Step-by-step explanation:

First four years

A = p(1 + r/n)^nt

P = £2350

r = 4.2% = 0.042

n = 1

t = 4

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Next 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

7x - 2y = 1
2y = x - 1
Solution as (x,y)
I am really confused please help!!!!

Answers

Answer:

Step-by-step explanation:

Simplifying

7x + -2y = 1

Solving

7x + -2y = 1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

7x + -2y + 2y = 1 + 2y

Combine like terms: -2y + 2y = 0

7x + 0 = 1 + 2y

7x = 1 + 2y

Divide each side by '7'.

x = 0.1428571429 + 0.2857142857y

Simplifying

x = 0.1428571429 + 0.2857142857y

///////////////////////

Simplifying

2y = x + -1

Reorder the terms:

2y = -1 + x

Solving

2y = -1 + x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = -0.5 + 0.5x

Simplifying

y = -0.5 + 0.5x

Answer:

1) y = − 1 2 + 7 x 2

2)  x = 2 y + 1

Step-by-step explanation:

Subtract 7 x from both sides of the equation. − 2 y = 1 − 7 x Divide each term by − 2 and simplify.

y = − 1 2 + 7 x 2

Solve for x by simplifying both sides of the equation, then isolating the variable. x = 2 y + 1

The graph below shows a company's profit f(x), in dollars, depending on the price of pencils x, in dollars, sold by the company:

Graph of quadratic function f of x having x intercepts at ordered pairs negative 0, 0 and 10, 0. The vertex is at 5, 160.

Part A: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? (3 points)

Part B: Describe the constraints of the domain. (3 points)

Answers

Answer:

A. The maximum represents the most amount of pencil price in dollars sold for the most amount of profit and the x-intercepts represent the profit when it is. The intervals at where the function increases represents a bigger profit for a price, whereas a decreasing interval represents a lower profit for a price.

Step-by-step explanation:

my answer for my test

The average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Average rate of a function:

= (160-100)/5-2

= 20

For every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

Because prices are rarely negative, the domain is most likely confined to 0≤x. The price may be set so high that it yields a loss, but that is not a viable option. As a result, x ≤10 is the upper limit of the sensible domain.

Thus, the average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

Answers

Answer:

5h ≤ 20 or h ≤ 4

Step-by-step explanation:

Lia walks at a rate of 5 miles per hour.

Lia has a goal of walking at least 20 miles

Let h be the number of hours she should walk in order to meet or exceed her goal.

At least in inequality means ≤. ATQ,

5h ≤ 20

Dividing both sides by 5.

h ≤ 4

So, she should walk atleast 4 hours. Hence, the correct option is (b).

The blueprint of a concrete patio has a scale of 2 inches = 3 feet. On this blueprint, the width of the patio is 12 inches. You want to create a NEW blueprint using a scale of 1 inch = 2 feet. What will be the width of the patio on your new blueprint?

Answers

Answer:

[tex]9\ \text{inches}[/tex]

Step-by-step explanation:

[tex]2\ \text{inches}[/tex] of the blueprint is [tex]3\ \text{feet}[/tex] of the actual concrete patio.

So [tex]1\ \text{inch}[/tex] of the blueprint = [tex]\dfrac{3}{2}\ \text{feet}[/tex] of the actual concrete patio

Width of the patio in the blueprint is [tex]12\ \text{inches}[/tex].

So [tex]12\ \text{inches}[/tex] of the blueprint = [tex]12\times \dfrac{3}{2}=18\ \text{feet}[/tex] of the actual concrete patio.

Now for the new blueprint [tex]1\ \text{inch}=2\ \text{feet}[/tex] of the actual concrete patio.

[tex]1\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{1}{2}\ \text{inch}[/tex] of the new bluprint.

So, [tex]18\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{18}{2}=9\ \text{inches}[/tex] of the new blueprint.
