Answer:
500
Step-by-step explanation:
Answer:
No, he not correct because he only ran 4 mi
Step-by-step explanation:
If he walks for 6 min out of the 38 min, then he ran for 32 min.
d = rt 1 mi = 8r
r = 1/8 = 1 mi/8 min Since he ran 32 min we have
d = 1/8(32) = 4 mi.
No, he not correct because he only ran 4 mi
Length: L=8 feet
Width: W=2 feet
Center is located at 0,0 → C=(0,0)=(h,k)→h=0, k=0
<span>The surfboard is lying on the ground horizontally:
x^2/a^2+y^2/b^2=1
L=2a→2a=8 feet
Solving for a:
2a/2=(8 feet) / 2
a=4 feet
W=2b→2b=2 feet
Solving for b:
2b/2=(2 feet)/2
b=1 feet
Replacing a=4 and b=1 in the equation (1):
(1) x^2/a^2+y^2/b^2=1
x^2/4^2+y^2/1^2=1
x^2/16+y^2/1=1
x^2/16+y^2=1
Answer: Equation of the sufboard:
x^2/16+y^2=1 </span>
Answer:
<em></em><em></em>
<em></em>
Step-by-step explanation:
Given
------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
<em>Up till the ninth switch</em>
<em></em>
<em>So, we have that:</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
Hence, there are 512 possible codes
