Answer:
It's form. Linear is a normal line, exponential is a curvy line, and quadratic is a u shape with the vertice on the y-axis line, making half of the u on the left quadrant and the other half on the right quadrant
Step-by-step explanation:
first is linear, second is exponential and third is quadratic
first we do
square is length 6 so base =6
10-6=4
the rectangle is 2 by 4
base=4
square is 6 by 6
rectangle is 4 by 2
split the triangles up
area of triangle=1/2base times height
rectangle triangle base=4
height=2, area=1/2 times 2 times 4=4
square triangle
flip 90 degrees clockwise so we have base=2
height=6
area=1/2 times 2 times 6=6
add
4+6=10
total area=10m^2
Answer:
c you go over seven and up three
2 seperate questions
what is the weight of 1 gallon and what is the cost per gallon
weight/1gallon=wieght/gallons=129.8lb/22gal=5.9lb/1gal
weigth is 5.9lb per gallon
cost per gallon=cost/gallons=$91.30/22gal=$4.15/1gal
cost is $4.15 per gallon
if ya wanted to estimate
lb per gallon is 129.8lb/22gal≈130/20=6.5lb/gal=6.5lb per gal
cost is $91.30/22gal ≈90/20=9/2=$4.50 per gal
Answer:
2 cis (7/6 pi)
Step-by-step explanation:
r = sqrt( a^2 + b^2)
r = sqrt (-sqrt(3) )^2 + (-1)^2)
= sqrt(3 +1)
= sqrt(4)
= 2
theta = arctan (b/a)
theta = arctan (-1/-sqrt(3))
theta = 30
but this is in the third quardrant -a and -b
so add 180
theta = 210 degrees
convert this to radians
210 * pi/180 = 210/180 * pi = 21/18 * pi = 7/6 * pi
r cis (theta)
2 cis (7/6 pi)
