Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
The range of a function is the set of all values that it can take when its independent variable takes values on the domain.
On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.
In the case of the given equation:
![y=-4x+1](https://tex.z-dn.net/?f=y%3D-4x%2B1)
The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:
![x=-\frac{1}{4}(y-1)](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B1%7D%7B4%7D%28y-1%29)
If the range of the original function is the set given by the number {
Answer:
150 cm²
Step-by-step explanation:
A cube has 6 surfaces.
A cube has equal length for all edges.
Area of 1 surface = 5 x 5 = 25 cm²
Area of 6 surfaces = 25 x 6 = 150 cm²
