I won’t! it’s very pretty!
X would equal 3 and y would equal 7
thanks for the points to mate
20/52 = b/100
20 x 100/52 x b
2000/ 52b
b = 38.5
Explanation:
b is a variable that stands for the unknown quantity
Write 20/52 as equal to b/100
Next we cross multiply 20 by 100 = 2000 and 52 by b = 52b
2000/52b is equal to 38.46 but roundest to the nearest tenth it is 38.5
Given the function:
![f(x)=\sqrt[]{x^2+6x}-x](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B%5D%7Bx%5E2%2B6x%7D-x)
the graph of the function will be as follows:
As shown in the figure:
The domain is the values of x which can be f(x) is valid
As the function contain a square root, so, the root must be greater than or equal to zero
so, the domain will be:
The Y-intercept is the value of y which make x = 0
So, as shown: y-intercept = 0
The x-intercept is the value of x which make y = 0
So, as shown: x-intercept = 0
Answer:
x = 5√3; y = 5
Step-by-step explanation:
Finding y: The sine function links the 30° angle, the 10 unit hypotenuse and the side opposite the angle, y:
sin 30° = 1/2 = y/10
Solve the equation of ratios
1 y
-- = ----- using cross-multiplication first: 2y = 10 → y = 5
2 10
We can now find x either by using a similar approach and the cosine function or by using the Pythagorean Theorem:
x² + y² = 10² = 100 → x² = 100 - y² = 100 - 5² = 75
If x² = 75, then x = ±√75 = ± (√25)·(√3) → ±5√3
Since lengths are always positive, take x = 5√3 as the answer.
