Answer:

7
-1 2/3
4

Step-by-step explanation:

The average rate of change of a function f(x) on interval [a, b] is the slope of the line through points (a, f(a)) and (b, f(b)). The slope formula tells you that is ...

m = (f(b) -f(a))/(b -a)

1) The rate of change in the interval [1, 2] is ...

rate of change = (2³ -1³)/(2 -1) = (8 -1)/1 = 7

2) rate of change = ((√4 -8) -(√1 -2))/(4 -1) = (-6-(-1))/3 = -5/3

3) rate of change = (11 -(-1))/(5 -2) = 4

Find slope of a straight line if both intercept are equal

Juli2301 [7.4K]

Answer:

-1

Step-by-step explanation:

Let the points be (0, a) and (a, 0) (As it mentions the intercepts are equal)

==============================================================

Applying slope formula :

⇒ m = 0 - a / a - 0

⇒ m = -a/a

⇒ m = -1

In a photograph, a house is 4 inches wide and 6 inches tall. The photograph is enlarged while keeping proportional dimensions, a

AlekseyPX

Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height $h$ , the preservation of the width/height ratio is written as

$4 \div 6 = 9 \div h$

Solving the proportion for $h$ yields

$h = \frac{6\cdot 9}{4} =\frac{3\cdot 9}{2} = \frac{27}{2} = 13.5$
