50 total students

20 girls

Explanation:

total students: 100%

----------------

60% → 30

1% → 30/60

1% → 0.5

100% → (0.5 * 100)

100% → 50

number of girls:

total students - number of boys

50 - 30

Answer:

reflected across the x-axis
vertically stretched by a factor of 2
translated down 7 units

Step-by-step explanation:

When the function y = x³ is transformed to y = -2x -7, there are three transformations involved. The multiplication by 2 causes a vertical stretch by a factor of 2. The leading minus sign causes the function to be reflected over the x-axis, and the addition of -7 causes the graph to be translated down 7 units.

Suppose that x and y are both differentiable functions of t and are related by the given equation. Use implicit differentiation

stepan [7]

Answer:

Let z = f(x, y) where f(x, y) =0 then the implicit function is

$\frac{dy}{dx} =$ $\frac{-δ f/ δ x }{δ f/δ y }$

Example:- $\frac{dy}{dx} = \frac{-(y+2x)}{(x+2y)}$

Step-by-step explanation:

Partial differentiation:-

Let Z = f(x ,y) be a function of two variables x and y. Then

$\lim_{x \to 0} \frac{f(x+dx,y)-f(x,y)}{dx}$ Exists , is said to be partial derivative or Partial differentiational co-efficient of Z or f(x, y)with respective to x.

It is denoted by δ z / δ x or δ f / δ x

Let Z = f(x ,y) be a function of two variables x and y. Then

$\lim_{x \to 0} \frac{f(x,y+dy)-f(x,y)}{dy}$ Exists , is said to be partial derivative or Partial differentiational co-efficient of Z or f(x, y)with respective to y
