Answer:

a=2

Step-by-step explanation:

Please see attached picture for full solution.

Method 1: Substitute x with another number, other than the numbers that you have already tried. Zero is a good number to work with :)

Then, subst. the values of b and c which you have already found into the equation. Then simplify to arrive at your answer.

Method 2: Notice that when you expand the right hand side, only a(x)({x}^{2}) can give you a x^{3}term. Hence, compare the coefficients of {x}^{3} on both sides. This method is quite safe since the value of a won't be affected in case the value of b and c is wrong.

The area of a circle is 16pi cm2. What is the circle's circumstance?
gavmur [86]
I think you mean circumference...Area is A= \pi  r^{2}. We have the area so we need to use it to solve for the radius which we will then use in the circumference formula.  16 \pi = \pi  r^{2}.  Divide both sides by pi to get \frac{16 \pi }{ \pi } = r^{2}.  Of course the simplification of the left side gives us 16= r^{2} and r = 4.  Now fill that in to the circumference formula, which is C=2 \pi r, to get CC=2 \pi (4) which is a circumference of 8 \pi

A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
statuscvo [17]

Answer:

Cost price of the fan is \text {Rs. 470.59}.

Step-by-step explanation:

Given: A man sold a fan for  \text{Rs.}\:400. He incurred a loss of 15\%.

To find: The cost price of the fan

Solution:

We have,

Selling price, S.P.,  of the fan = \text{Rs.} 400

Loss =15\%

We know that \text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%

Now let the C.P. of the fan be \text{Rs.} \:x

So, 15=(\frac{x-400}{x})\times 100

\implies 15x=100x-40000

\implies 100x-15x=40000

\implies 85x=40000

\implies x=\frac{40000}{85}

\implies x= 470.59

Hence, the cost price of the fan is \text {Rs. 470.59}.

If A(−2, 1), B(1, 5), C(4, 4), and D(1, 0) are the vertices of a quadrilateral, do the points form a parallelogram? Justify your
Alexandra [31]
<span>Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals negative start fraction four over three end fraction, and AD = BC = 10 units.</span>
