Answer:
first box is x+3
second box is 5
Step-by-step explanation:
To find the first f(x) equation , lets pick two points from the slanting line
(-3,0)(-2,1)
lets find the equation of this line
we need find equation y=mx +b
m=1 and point is (-3,0)
use formula y-y1=m(x-x1)
y-0 = 1(x-(-3))
y= 1(x+3)
y= x+3
another line is a horizontal line
for horizontal line , slope is always 0
we have line at 5 on y so equation is y=5

Answer:
The cellphone towers height is 1020 ft.
Step-by-step explanation:
This question is solved using proportions, by a rule of three.
A 10-ft post casts a 14-inch shadow.
Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?
10 feet post - 1.167 ft shadow
x feet tower - 119 feet shadow
Applying cross multiplication:
The cellphone towers height is 1020 ft.
Answer:
222.7 cm³ of paper to wrap this.
Step-by-step explanation:
The rectangular prism is SA=2(wl+hl+hw)
Where:
w=5 l=5 h=4
SA= 2((5*5)+(4*5)+(4*5))
SA=2(25+20+20)
SA=2(65)=130cm³
The square base pyramid is
≈92.69578 cm³
Add the two together 130+92.70 =222.7 cm³
