When e = 4, f = 2, and g = 8If e varies jointly with f and g, what is the constant of variation?

tatyana61 [14]

Answer:

$e=\frac{1}{4} fg$

Step-by-step explanation:

Joint variation problem solve using the equation y = kxz.

e ∝ fg

e=kfg

now substitute the values

$4=k*2*8\\4=16k\\k=\frac{4}{16} \\k=\frac{1}{4}$

The relationship will be:

$e=kfg\\e=\frac{1}{4} fg$

C= 5/9 (F−32)

Grace [21]

Answer:

C = 5/9 (F - 32)

This is a temperature scale change comparison.

By this we understand, that ,

1°C = 5/9°F

Which is equal to, 5/9°F = 1°C

These two statements are satisfied by I. and II.

So, the correct answers are, I. and II.

Step-by-step explanation:

-2 = 17

You need find what number that need to be in the blank spot

17 + 2 = 19

19 - 2 = 17

In the second question u need to find equal number

17 - 3 = 16 - 2

14 14

They need to be equal - =

19 - 6 = 18 - 5

I need help with these questions for Quadratic functions

STALIN [3.7K]

9514 1404 393

Explanation:

1. The general form of a quadratic in standard form* is ...

$f(x)=ax^2+bx+c$

An example is ...

$f(x)=2x^2+3x-5$

The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.

2. The general form of a quadratic in vertex form can be written as ...

$f(x)=a(x-h)^2+k$

An example is ...

$f(x)=2(x -3)^2 -5$

The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.

_____

* In the UK, "standard form" is vertex form.
