Answer: f(x) = 3
Step-by-step explanation: 3
(assume that the three in front is a part of the cube root function)
In order to shift a parent function to the left two you need to add it on the inside (in this case underneath the cube root). Adding on the inside does the opposite if you were adding on the outside, so instead of moving it to the right, it moves it left. In order to slide a function up or down you need to add or subtract a number on the outside of the function. In this case you need to add 3 at the end.
Answer:
The truck have travelled 345.5 inches after 5 rotations of the tires
Step-by-step explanation:
Given:
Diameter of the tyre= 22 inches
Number of rotations= 5
To find:
Distance travelled after 5 rotations=?
Solution:
We have given with diameter,
So let radius be r
r=
r=11 inches
The distance covered by one rotation is given by circumference
Circumference =
Substituting the values, we get
Circumference =
Circumference =
Circumference =
Circumference =
Circumference = 69.11
Now for 5 rotation,
Distance travelled =
Distance travelled =
Distance travelled =
The truck will travel 345.5 inches.
Answer:
see explanation
Step-by-step explanation:
The angle at the circumference b , is half the angle subtended at the centre by the arc XZ, that is
b = 0.5 × 72 = 36
OZ and OX are congruent ( both radii of the circle )
Thus Δ OXZ is isosceles with base angles congruent, thus
a = =
= 54
∠ XZY = 90° ( angle in a semicircle is right )
