Amir buys a new car for £16470. The value of the car will depreciate by 2% each year. Work out how much amir's car will cost after 23 years
Answer:
Amir's car will cost £10348.88 after 23 years.
Step-by-step explanation:
I finally found a UK human!
This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.
The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.
16470 × [tex]0.98^{23}[/tex] = £10348.88
I hope that helps you!! ^-^
What is p / r equal to?
Using our trig functions, we know that tan x = opposite side of a right triangle divided by the adjacent side of the right triangle.
So, tan x = p/r.
Answer: tan x°
The trigonometric function gives the ratio of different sides of a right-angle triangle. The ratio of p and r can be written as tan(x°) and sec(y°).
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
As per the given figure, the ratio of the p\r can be written as shown below,
In terms of angle x,
tan(x°) = p units / r units
tan(x°) = p/r
In terms of angle y,
tan(y°) = r / p
1 / tan(y°) = r/p
sec(y°) = r/p
Hence, the ratio of p and r can be written as tan(x°) and sec(y°).

Answer:
6 ≤x
Step-by-step explanation:
12 + 11/6x ≤ 5+3x
Subtract 11/6x from each side
12 + 11/6x - 11/6x ≤ 5+3x-11/6x
Subtract 5 from each side
12 + 11/6x - 11/6x -5 ≤ 5+3x-11/6x-5
7 ≤ 3x-11/6x
Get a common denominator
7 ≤ 18/6x-11/6x
7 ≤7/6x
Multiply each side by 6/7
6/7 *7 ≤ 6/7 *7/6x
6 ≤x
A 30-foot long escalator forms a 41° angle at the second floor. Which is the closest height of th
141
30 feet
A 20 feet
B. 22.5 feet
C. 24.5 feet
D. 26 feet
Answer:
[tex]\huge\boxed{\text{B) } 22.5 \ \text{feet}}[/tex]
Step-by-step explanation:
We can use basic trigonometric functions to find the closest height of the escalator.
Let's set up a picture from what we already know. The length of the escalator is 30 feet, and it forms a 41 degree angle with the top. Since it will form a 90 degree angle with the ground, we can find the angle between the ground and the beginning of the escalator.
Since all triangles have an angle sum of 180:
[tex]90+41+x=180[/tex] [tex]131+x=180[/tex] [tex]x = 180-131[/tex] [tex]x=49[/tex]Now we know that the triangle looks something like this.
/ | 41°
/ |
/ |
/ |
30 / |
/ |
/ |
/ |
/__________| 90°
49°
We need to find the length of the side between the 41 and 90° angle.
To find which trigonometric operation to use on this triangle, we can use the acronym SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
We can use the sine of the 49 degree angle (opposite / hypotenuse) to find our missing side (since we know the hypotenuse).
Let's set up an equation and solve with our calculator.
[tex]\text{sin}(49) = \frac{\text{opposite}}{\text{hypotenuse}}[/tex] [tex]\text{sin}(49) = \frac{x}{\text{30}}[/tex] [tex]30 \cdot \text{sin}(49) = x[/tex]We can calculate the sine of 49 with our calculator. We'd end up multiply 30 and that value and get 22.6.
Since the closest value to 22.6 on the answer choices is 22.5, the correct answer would be B) 22.5 feet.
Hope this helped!
Answer:

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.
It is spun twice.
What is the probability of not getting two consecutive blues?
Answer:
8/9 or 88.89%
Step-by-step explanation:
Spinner has a total of 9 sections.
These sections are;
2 red, 3 blue and 4 green.
Now, probability of getting blue at one spin = 3/9 = 1/3
Probability of getting 2 consecutive blues = ⅓ × ⅓ = 1/9
Probability of not getting 2 consecutive blues = 1 - probability of getting 2 consecutive blues = 1 - 1/9 = 8/9 or in percentage 8/9 × 100% = 88.89%
