a shape is shown on the centimetre grid below work out the area of the shape after it has been enlarged by scale factor 2 state the units of your answer
Answer:
20 cm²
Step-by-step explanation:
If the given shape has been enlarged by scale factor 2, then each of the side lengths will be increased from 1 cm to 2 cm, as 1 × 2 = 2
Area of the given shape is 5 cm².
As we are working with area, we cannot simply multiply the area of the given shape by the scale factor. Area is measured in square units, therefore we need to multiply the area of the given shape by the square of the scale factor.
⇒ area of the enlarged shape = area of given shape × sf²
= 5 cm² × 2²
= 5 cm² × 4
= 20 cm²

Tracey bought a diamond ring appraised at $1200 at an antique store. If diamonds have appreciated in value at an annual rate of 12%, what was the value of the ring 10 years ago? (Round your answer to the nearest dollar.)
Answer:
1600 / 1.1^10 = $616.87
Step-by-step explanation:
Im not so sure, but here
the value of the diamond ring 10 years ago was approximately $419.47
To find the value of the diamond ring 10 years ago, we need to calculate its original value before the annual appreciation.
Let's assume the original value of the ring 10 years ago was "x" dollars.
After 10 years, with an annual appreciation rate of 12%, the value of the ring became $1200.
The formula to calculate the future value (FV) of an investment with compound interest is:
FV = PV * (1 + r)ⁿ
where:
FV = future value
PV = present value (original value)
r = annual interest rate (as a decimal)
n = number of years
In this case, we have:
FV = $1200 (present value after 10 years)
r = 12% (0.12 as a decimal)
n = 10 years
Now, we can rearrange the formula to find the original value (PV):
PV = FV / (1 + r)ⁿ
PV = $1200 / (1 + 0.12)¹⁰
PV = $1200 / 2.85610019
PV ≈ $419.47
So, the value of the diamond ring 10 years ago was approximately $419 (rounded to the nearest dollar).

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.
We have a function:
y = 2(x – 5)² – 6
Part A:
Using vertical line test, we can find the whether the graph is a function or not.
After drawing a graph for the given curve, and drawing a vertical line.
The vertical line touches only one point for the one input.
The given equation represents a function.
Part B:
Replace x → y and y → x
x = 2(y – 5)² – 6
2(y – 5)² = x + 6
[tex]\rm y^-^1 = \sqrt{\dfrac{x+6}{2}} +5[/tex]

Jaxon is flying a kite, holding his hands a distance of 3.25 feet above
the ground and letting all the kite's string play out. He measures the
angle of elevation from his hand to the kite to be 24°. If the string from
the kite to his hand is 105 feet long, how many feet is the kite above the
ground? Round your answer to the nearest tenth of a foot if necessary.
Using the slope concept, it is found that the kite is 46.50 feet above the ground.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem:
The angle is of 24º.The vertical change is of 3.5 + x.The horizontal change is of 105.Hence:
tan(24º) = (3.5 + x)/105.
3.5 + x = 105tan(24º)
x = 105tan(24º) - 3.5
x = 43.25 ft.
Hence, the height of the kite is:
43.25 ft + 3.25 ft = 46.50 feet.

Steve hade 17 pencils in his backpack. this represents 5 more than 6/7 the number of pencils that Clyde has in his backpack
Answer:
Clyde has 14 pencils in his backpack
Step-by-step explanation:
Let x be the number of pencils that Clyde has in his backpack.
We can translate this statement “Steve hade 17 pencils in his backpack. this represents 5 more than 6/7 the number of pencils that Clyde has in his backpack” mathematically like this :
[tex]17=5+\frac{6}{7} x \\\\ \Longleftrightarrow 17-5=\frac{6}{7} x \\\\ \Longleftrightarrow 12=\frac{6}{7} x \\ \\\Longleftrightarrow x=\frac{12\times 7}{6} =14[/tex]
Let he has n pencils
So

A jogger on the beach at Cape Hatteras covered 8 miles at a constant speed. Given that distance run varies directly as time, what is the constant of variation in miles per hour if it took the jogger 45 minutes to cover the 8 miles?
The velocity of the jogger will be 0.18 miles per minute.
What is velocity?Velocity is defined as the ratio of the distance moved by the object in a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
Given that:-
It took the jogger 45 minutes to cover the 8 milesThe velocity will be calculated as:-
V = Distance ÷ Time
V = 8 ÷ 45
V = 0.18 miles per minute
Therefore the velocity of the jogger will be 0.18 miles per minute.

how many solutions does the following equation have? explain
5x- 3x + 5 = 8x +5
Answer:
Plug into desmos, the exact equation, and put in what point comes out.
Step-by-step explanation:
Answer:
Once fully solved, x is equal to 0, so it means that there is only one solution
Step-by-step explanation:
When you combine like terms (without adding variables to either side), the equation is equal to:
2x + 5 = 8x + 5
Then, the next step is:
5 = 8x + 5 - 2x
Finally, the last one is:
0 = 6x, which is x = 0.

If two samples are drawn randomly from the same population and sample A has n=350 and sample B has n=500, which sample will have a larger standard error of the mean?
Group of answer choices
Sample B
Sample A
The standard errors will be the same
Reason:
The standard error of the mean has the formula [tex]\frac{\sigma}{\sqrt{n}}[/tex] where [tex]\sigma[/tex] (greek letter sigma) is the standard deviation and n is the sample size.
As n gets bigger, the standard error [tex]\frac{\sigma}{\sqrt{n}}[/tex] gets smaller, and vice versa. This assumes sigma is fixed. A larger sample indicates the error goes down to narrow in better on the population mean.
Based on what I mentioned, this tells us that sample A has the larger standard error since n = 350 is smaller than n = 500 for sample B.

Aiden earned $334.40 at his job when he worked for 16 hours. How much money did he earn each hour?
Answer:
$20.90
Step-by-step explanation:
If we want to find Aiden's hourly rate, and we know how long he worked, and how much money he made, then we can simply divide his profit by how long he worked. This will give us the precise amount of money he made per hour.
So,
$334.40 / 16 hours = 20.9
This means Aiden earned approximately $20.90 per hour.
