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?
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
Why are equivalent equations important when solving a system using linear combination?
Answer:
Linear equations are an important tool in science and many everyday applications. They allow scientist to describe relationships between two variables in the physical world, make predictions, calculate rates, and make conversions, among other things. Graphing linear equations helps make trends visible.

Lia has a goal of walking at least 20 miles. She walks at a rate of 5 miles per hour. Which inequality can Lia use to find h, the number of hours she should walk in order to meet or exceed her goal? A. 5h ≥ 20 B. 5h ≤ 20 C. H+5 ≥ 20 D. H+5 ≤ 20
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).

I am really confused please help!!!!
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
Find the sum. (2x2 + 5x - 7) + ( 3 - 4x2 + 6x)

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?
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.

Karen rented a truck for one day. There was a base fee of $12.00, and there was an additional charge of 6 cents for each mile driven. The total cost, C (In dollars) for driving x miles is given by the following. C=12.00+0.06x what is the total rental cost if Karen drove 40 miles?
Answer:
$14.04
Step-by-step explanation:
base fee: $12.00
per mile: 0.06
miles driven: 40 miles
0.06 x 40= 2.04
12.00 + 2.04= 14.04
The cost would be $14.04

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)
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.
