Answer:
Plug in and determine solution
Step-by-step explanation:#9-11 plug in the degrees C on the left side of the table into the equation and that should give you the degrees F, something like with #9; F = 9/5 (0) + 32.
#12-13, they have a relationship because Celsius can be converted to Farenheit and vise versa
Answer:
45°, 225°
Step-by-step explanation:
Given that;
Tan x = 1
We can get Tan⁻¹ of 1
x = Tan⁻¹ 1
x = 45
45° is the acute angle in the first quadrant
Tangent is positive in the 1st, and the 3rd quadrant.
Therefore in the third quadrant, x = 180 + 45 = 225
Hence; x = 45° or 225°
Answer: 45000
Step-by-step explanation:
From the question, we are informed that Patty buys a new car and gets it appraised every few years and that after owning the car for 3 years, its value is $15,000 and further told that after owning the car for 5 years, its value is $9,000.
Let the number of years be x
Let the value of the car be y.
From the first part of the question, we are told that after owning the car for 3 years, its value is $15,000.
Since an inverse variation will be:
x = k/y
3 = k/15000
k = 15000 × 3
k = 45000
Let's confirm the value of k for the second part of the question. After owning the car for 5 years, its value is $9,000. Here, x=5 and y = 9000
x = k/y
x = 45000/9000
x = 5
It's correct.
Therefore, the constant of proportionality is 45000
Answer:
Beena = 19 years old
Seema = 28 years old
Step-by-step explanation:
Beena = x
Seema = x + 9
x + 9 + 10 = 2x
19 + x = 2x
2x - x = 19
x = 19
