Answer:
17 tenths - 8 tenths=9 tenths
Step-by-step explanation:
1.7 tenths is 17 tenths, we can see that by multiplying 1.7x10 to get 17
dot he sam with 0.8 to get 8 tenths
ti find the answer, subtract the units. 17-8=9
Answer:
B= 21° C= 29°
Step-by-step explanation:
Use sin rule.
1st one.
sin44°/33 = sinB/17
sinB= 17sin44/33
B= sin^-1 ( ans)
B= 20,97 =21°
2nd one.
sin92°/35 = sinC/17
sinC = 17sin92°/35
C= sin^-1 (ans)
C= 29,04° = 29°
Write 4 as a sum (8h-3j)^2+2
Use a m+n=a m•a n to expand the expression
(8h-3j)^2 x (8h-3j)^2
Use (a-b)^2= a^2... -2ab+b^2 to expand the expression
(64h^2 - 48hj+ 9j^2)x(64h^2 - 48hj+ 9j^2)
Multiply the parentheses and after you get your answer you collect like terms.
Your answer should be:
4096h^4 - 6144h^3j + 3456h^2j^2 - 864hj^3 +81j^4
Answer:
The new current is half the original current.
Step-by-step explanation:
Ohm's Law:
We use Ohm's law to solve this question. It states that
In which 
is the voltage difference, R is the resistence, and I is the current.
A student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference ΔV across the resistor.
So
![I_{1} = \frac{\Delta_V}{R}{/tex]Then, the student replaces the resistor with a new one of resistance 2R and keeps the electric potential difference the same.Now the current will be[tex]\Delta_V = 2RI_{2}](https://tex.z-dn.net/?f=I_%7B1%7D%20%3D%20%5Cfrac%7B%5CDelta_V%7D%7BR%7D%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3Cstrong%3EThen%2C%20the%20student%20replaces%20the%20resistor%20with%20a%20new%20one%20of%20resistance%202R%20and%20keeps%20the%20electric%20potential%20difference%20the%20same.%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3ENow%20the%20current%20will%20be%3C%2Fp%3E%3Cp%3E%5Btex%5D%5CDelta_V%20%3D%202RI_%7B2%7D)
The new current is half the original current.
It should be $57.75. You have to figure out how much she earns per hour first in order to solve this problem.
