Answer:
A square with a triangle connected to each side with a dotted line.
Step-by-step explanation:
we know that
A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
so
The net that represent the pyramid is
A square with a triangle connected to each side with a dotted line.
see the attached figure to better understand the problem
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
Answer: Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.
Step-by-step explanation:
To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.
Doctor A's mean:
Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = <em>751.6</em>.
Doctor B's mean:
Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = <em>755.2</em>
Difference:
755.2-751.6 = <em>3.6</em>
Answer:
$415.6
Step-by-step explanation:
Given data
Gross weekly pay = $440.00
<em />
<em>Taxes/deductible</em>
Medical insurance = $14.40
Union dues= $10.00
Total deductible= 14.4+10= $24.4
Hence the net pay
= $440-24.4
=$415.6
Answer:
The answer would be B because 3 times 4 equals 12 and 12+5 =17.
Step-by-step explanation:
1.) 3(4)+5=17
2.)12+5=17
3.)17=17
