The scientific notation 2 x 10-2 has what value?
Answers
Answer 1
Answer:
Since the exponent is negative, you move the decimal (2.0) to the left two spots leaving you with .02
Answer 2
Answer:
2(10^-2)
=2 * 10^-2
= 2 * 1/10 * 10
= 2/10 * 10
= 2/10^2
= 2/100
= 1/50 Decimal: 0.02
Q:The scientific notation 2 x 10-^2 has what value?0.020.0020.20.0002
A: The scientific notation 2 x 10^-2 has the value of 0.02
=2 * 10^-2
= 2 * 1/10 * 10
= 2/10 * 10
= 2/10^2
= 2/100
= 1/50 Decimal: 0.02
Q:The scientific notation 2 x 10-^2 has what value?0.020.0020.20.0002

Hi there, first let's add up the minutes, 30 minutes+15 minutes+20 minutes equals 65 minutes, 65 minutes equals 1 hour and 5 minutes. 7:15 pm, an hour before that is 6:15, 5 minutes before that is 6:10. Therefore, Leo needs to begin at 6:10 pm
6:10 pm if you want to be exact

area of a rectangle=length x width.
length=x
width=y
xy=32 ⇒y=32/x
perimeter of a rectangle=2x+2y
P(x,y)=2x+2y
P(x)=2x+2(32/x)
P(x)=2x+64/x
P(x)=(2x²+64)/x
1) we calculate the first derivative
y=u/v ; y´=(u`v-v´u) / v²
P`(x)=(4x*x-1(2x²+64)] / x²
P´(x)=(4x²-2x²-64) / x²
P´(x)=(2x²-64) / x²
2)we equalize the first derivative to "0" and we find out the value of x:
(2x²-64) / x²=0
2x²-64=0*x²
2x²-64=0
2x²=64
x²=64/2
x²=32
x=⁺₋√32
We obtein two possible values:
x₁=-√32; this value is not valid.
x₂=√32 ;
3)we calculate the second derivative:
P``(x)=[4x * (x²)-2x(2x²-64)] / x⁴
P´´(x)=(4x³-4x³+128x) / x⁴
P´´(x)=128/x³
4) we find out if x=√32 is a maximum or a minimum
P´´(√32)=128/(∛32)=40.317...>0;
Therefore, like P´´(√32)>0 at x=√32 we have a minimum
5) we find out the value of y.
y=32/x
y=32 / √32=(32*√32)/32=√32
Therefore: x=√32, y=√32, the rectangle is a square.
Perimeter=2x+2y
Perimeter=2√32+2√32=4√32
Answer: the least perimeter of a rectangle with an area of 32 ft² is 4√32 ft.

Answer: the least perimeter of a rectangle with an area of 32 ft² is 4√32 ft.
the smallest perimiter is when the sides are the same legnth
example
if you built a rectangle with area 20
if you built it wwith sides 20 and 1, then the perimiter would be 42
if you build it with sides 5 and 4, the perimiter is 18
so trry to get perimiters as clos as possible
get them equal
aera of rectangle=legnth times width
set legnth=width so we can get least perimiter
area of rectangle=legnth times legnth
area=legnth^2
32=legnth^2
sqrt both sides
√32=legnth
4√2=legnth
so since legnth=width, this rectangle is now a square (this is allowed becasue defenition of rectangle is 4 right angles, and all squares are rectangles, but that doesn't means all rectangles ar squares)
perimiter of square=4legnth
perimiter of this square=4*4√2=16√2
answer is 16√2 feet

Given:
Monday: 6 laps around a 0.25-mile track
Tuesday: 7 laps around a 0.25-mile track
Total miles jogged on both days.
0.25(6 + 7) = 0.25(13) = 3.25 miles
Mike jogged a total of 3.25 miles on Monday and Tuesday combined.
Monday: 6 laps around a 0.25-mile track
Tuesday: 7 laps around a 0.25-mile track
Total miles jogged on both days.
0.25(6 + 7) = 0.25(13) = 3.25 miles
Mike jogged a total of 3.25 miles on Monday and Tuesday combined.
All you have to do is add up the number of laps and multiply that by the distance for each lap so its (6 +7)*0.25.
6+7=13
13*0.25= 3.25 miles
ANSWER= 3.25 miles
6+7=13
13*0.25= 3.25 miles
ANSWER= 3.25 miles
