If a function is derivable at a point it is also continous at that point explain why?

Answers

Answer 1
Answer: For a function to have a derivative in a point has to be continuous at the point, that is, it has to be defined at that point, other wise the derivative would be meaningless.

how much did briana save by purchasing a backpack that cost $45 with a sales promotion of 20% off instead of a backpack that cost $42 with a sales promotion of 10% off?

Answers

Start by doing a proportion for each one. 20/100= x/45. 45 times 20 equals 900. 900 divided by 100 equals 9. So 20% off is $9 which makes you pay $36. Do the next proportion. 10/100=x/42. 42 times 10 is 420. 420 divided by 100 equals 4.2. You would get off $4.2 which makes you pay $37.8. $37.8-$36= $1.8. Your answer is $1.8

Can anyone help me, i dont understand this. will give you all my points, and brainliest. Match the transformation with the correct representation.
g(x)=f(x)+n A horizontal shift of f , n units left
g(x)=f(x)- n A vertical shift of f, n units up
g(x)=f(x+n) A vertical shift of f, n units down
g(x)=f(x-n) A horizontal shift of f , n units right

Answers

Step-by-step explanation:

Transformations of graphs are fairly simple. Start with a parent function, or g(x) = f(x).

To move the graph UP or DOWN, add that number on the outside of the parenthesis with x: g(x) = f(x) + n is up, g(x) = f(x) - n is down.

To move the graph RIGHT you must SUBTRACT from inside the parenthesis. g(x) = f(x - n)

To move the graph to the LEFT you must ADD from inside the parenthesis . g(x) = f(x + n)

Name the shaded angle in three different ways

Answers

Answer:

1. "angle HGJ" or "angle JGH" (∠HGJ or ∠JGH)

2. "angle G" (∠G)

3. "angle 3" (∠3)

Step-by-step explanation:

Three ways the shaded angle can be named:

1. We can use capital letters to name the shaded angle. The middle letter indicates the vertex. Thus, we would name the shaded angle as: "angle HGJ" or "angle JGH". G is the middle letter, which indicates the vertex of the angle. Most often, the symbol "∠" is usually used to represent the word "angle". In short form, the shaded angle can be named as:

"∠ HGJ" or "∠ JGH"

2. The shaded angle can also be named according to the vertex. Thus, G is the vertex. The angle can be named "angle G" or "∠G"

3. Numbers can be placed at the vertex of the angle, and named accordingly. Thus, the shaded angle of which the vertex is labelled "3" can be named as "angle 3" or "∠3"
