First, lets break down the sample equation: y=-2x+7
-2=m=slope
+7=b=Y-intercept
Using process of elimination:
A is not perpendicular because the angle created by slopes is unequal to 90
B and D are quadratic equations, and have no correlation with the sample equation
C is parallel to the sample equation
Is there a typo in your question? None of these answers are correct, but I am wiling to keep helping you, I enjoy Algebra.
X^2/3 = 64


it is easier to first find square root of 64 and than power it to 3
square root of 64 is 8 which means our equation now looks like:
x = 8^3
now the answer is after powering 8 to 3:
x = 512
Answer:
Step-by-step explanation:
width=
=150 m
perimeter=(150+200)2
=700 m
area=150(200)
=30000 m²
Answer:
Answer: 455 / 7
Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?
answer choices
455 ÷ 70
455 ÷ 7
45.5 ÷ 7
4.55 ÷ 0.70
The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.
And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.
Only the second option does not do so. 455 / 70 = 65
Answer:

Step-by-step explanation:
Before we even begin it would be very helpful to draw out a simple layout of the circuit. Then we go ahead and apply kirchoffs second law(sum of voltages around a loop must be zero) on the circuit and we obtain the following differential equation,

where V is the electromotive force applied to the LR series circuit, Ldi/dt is the voltage drop across the inductor and Ri is the voltage drop across the resistor. we can re write the equation as,

Then we first solve for the homogeneous part given by,

we obtain,

This is only the solution to the homogeneous part, The final solution would be given by,

where c is some constant, we added this because the right side of the primary differential equation has a constant term given by V/R. We put this in the main differential equation and obtain the value of c as c=V/R by comparing the constants on both sides.if we put in our initial condition of i(0)=0, we obtain
, so the overall equation becomes,

where if we just plug in the values given in the question we obtain the answer given below,
