Answer:
Step-by-step explanation:
If parallel lines don't intersect, then there can't be any solutions. An intersection represents a solution.
If this is a true false question, the statement is false.
Answer: 5 dots should be placed on value 2.
Step-by-step explanation:
9/5 is the answer. Add 1/7 and 1/3 which equals 10/21. Then multiply on both sides by 21/10
Answer:
m∠E = 60°
Step-by-step explanation:
The given information in the diagram are;
The shape of the drawing, ΔEDF = A right triangle
The length of the hypotenuse side opposite the right angle = 16·√46
The length of the leg adjacent to the reference angle ∠E = 8·√46
By trigonometric ratio, we have;
Plugging in the values gives;
∴ m∠E = arccos(1/2)
Using a calculator or from tables or an online trigonometric ratio tool, we have
arccos(1/2) = 60°
∴ m∠E = arccos(1/2) = 60°.
The question is asking us to find the inverse of the function: f(x) = 2 x^2. The original function is: y = 2 x^2. First we have to interchange x and y and then to solve the function for y. So the 1st step: x = 2 y^2. Then: y^2 = x / 2 . Finally we have to take the square root of both sides of equation: y = sqrt( x / 2 ). Answer: The inverse is: <span>f^(-1) ( x ) = sqrt( x / 2 ) </span>
