I did the math
Answer:
a = b = 1
Step-by-step explanation:
The triangles are similar thus ratios of corresponding sides are equal, that is
=
( cross- multiply )
10b = 10 ( divide both sides by 10 )
b = 1
and
=
( cross- multiply )
10a = 10 ( divide both sides by 10 )
a = 1
Thus a = 1 and b = 1
Answer:
k ≥2
Step-by-step explanation:
k+ 1/3≥7/3
Subtract 1/3 from each side
k+ 1/3-1/3≥7/3-1/3
k ≥6/3
k ≥2
Answer:
From the analysis W1=W2.
they are directly related
Step-by-step explanation:
the work-done in stretching a spring can be expressed as
![W=\frac{1}{2}kx^2](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dkx%5E2)
where k= spring constant
x= change on length of spring
Hence for W1
Given data
x= 34-24= 10 cm
solving in terms of k we have
![W=\frac{1}{2}k*10^2\\\W=\frac{1}{2}k*100\\\W=50k](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A10%5E2%5C%5C%5CW%3D%5Cfrac%7B1%7D%7B2%7Dk%2A100%5C%5C%5CW%3D50k)
Hence for W2
Given data
x= 44-34= 10 cm
solving in terms of k we have
![W=\frac{1}{2}k*10^2\\\ W=\frac{1}{2}k*100\\\ W=50k](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A10%5E2%5C%5C%5C%20W%3D%5Cfrac%7B1%7D%7B2%7Dk%2A100%5C%5C%5C%20W%3D50k)
Answer:
9/8
Step-by-step explanation:
the quotient of -3/8 and -1/3
= (-3/8) / (-1/3)
= (-3/8) x (-3/1)
= 9/8
