Answer: If the plane is perpendicular to the line, the normal vector of the plane is equal to the direction vector of the line
Step-by-step explanation:
Answer:
For a single value of x function has more than one corresponding value of y which satisfies the equation.
Step-by-step explanation:
Function: A relationship between a set of inputs and a set of possible outputs, where exactly one output is associated with each input.
It means for an equation to represent a function any single value of x there should be only one corresponding value of y which satisfies the equation.
Now consider the given equation.
If we put x=0 then we get two value of y i.e and which satisfy the equation and therefore the equation is not a function.
Answer:
4.7 yd
Step-by-step explanation:
The horizontal lines in the diagram are parallel, so the angle of depression at D and the angle of elevation at F are congruent. So, you have a right triangle with the measure of one acute angle (F) and the length of the adjacent side (EF = 10 yd). You are being asked to find the opposite side (DE).
The mnemonic SOH CAH TOA reminds you of the necessary relation:
Tan = Opposite/Adjacent
Filling in the given information, you have ...
tan(25°) = DE/(10 yd)
Multiplying by 10 yd gives ...
(10 yd)tan(25°) = DE ≈ 4.663 yd ≈ 4.7 yd
Answer:
Step-by-step explanation:
Given:
Base length:
A = 8.5 m
B = 4 m
Height, h = 2 ft
1 gallon = 350 ft^2
Area of trapezoid = 1/2 × (A + B) × h
= 1/2 × (8.5 + 4) × 2
= 12.5 ft^2
1 gallon = 350 ft^2
2 gallons = 700 ft^2
1 podium = 12.5 ft^2
= 700/12.5 podium
= 56 podiums will be painted with 2 gallons of paint.
