The ratio for population density is population:area
Using this, we find that choices 1, 4, and 5 are true,
:)
Answer:
Step-by-step explanation:
take two points to find the equation:
(0,4),(-2,0)
y= 2x+4
domain is where the equation is defined ( x inputs)
Range is the set of values that correspond with the domain(y outputs)
the domain and the range are all real number
domain(-∞,∞) , range (-∞,∞)
(sinx)^2 = 1 when cosx is 0 at pi/2 and 3pi/2
cosx = 1 when sinx is 0 at 0
therefore, A
Answer:
80 in^2
Step-by-step explanation:
8*4=32
32/2=16
16= One triangle
16*4 triangles=64
4*4=16
64+16=80
Answer:
yes ; 17.5 ft
Step-by-step explanation:
Triangle PRQ is isosceles
the base angle are equals
we know two legs, so we can find the tangent of angle x
tan = opposite/adjacent
tan = 7/16 = 0.4375
the angle x measure 23.6 degrees circa (we can calculate this with the button tan -1 on the calculator)
the roof is safe
B we can use the Phytagorean theorem to solve this
PR = √16^2 + 7^2 = √256 + 49 = 17,46... = 17.5 ft
