Here's is a graph of that function. The 2 is the amplitude of the graph. Meaning the difference from top to bottom is 2, 3-1 is 2

The +1 moves the whole graph up one unit and the minus pi shifts the whole graph left by a length of pi.

The Schuller family has five members. Dad is 6ft 2in tall. Mom is 3 inches shorter than Dad, but 2 inches taller than Ivan. Marc

ohaa [14]

Answer:

62 inches

Step-by-step explanation:

Let x be the height ( in inches ) of Ivan,

∵ Marcia is 5 inches shorter than Ivan,

height of Marcia = x - 5,

Marcia is twice as tall as Sally-Jo,

height of sally-jo = $\frac{x-5}{2}$

Mom is 2 inches taller than Ivan.

⇒ height of mom = x + 2,

Mom is 3 inches shorter than Dad,

height of dad = x + 2 + 3 = x + 5,

So, mean height of family is,

$\frac{x+x-5+\frac{x-5}{2}+x+2+x+5}{5}$

$=\frac{2x+2x-10+x-5+2x+4+2x+10}{10}$

$=\frac{9x-1}{10}$

According to the question,

x + 5 = 74 ( 1 ft = 12 in )

x = 69

Hence, mean height of the family = $\frac{9\times 69-1}{10}$

$=\frac{620}{10}$

= 62 inches

Can someone plzzz help me ill give you pizza :((

den301095 [7]

Answer:

C. 1.5w^2 + 7.5w + 9

Step-by-step explanation:

Without frame:

The width is w. The height is 1.5w.

With frame:

The width is w + 1.5 + 1.5 = w + 3

The height is 1.5w + 1.5 + 1.5 = 1.5w + 3

The area of the framed portrait is height * width

area = (1.5w + 3)(w + 3)

area = 1.5w^2 + 4.5w + 3w + 9

area = 1.5w^2 + 7.5w + 9
