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

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.

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).

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

Step-by-step explanation:
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.
