Option B;
A suitable x-coefficient for a quadratic function that factors into a perfect square has to be even.
Nonamiya [84]3 years ago
6 0

Answer:

Option B is correct.

Step-by-step explanation:

We will work with the formula : (a+b)^{2}

= a^{2}+2ab+b^{2}

Given polynomial is :

64x^{2} +49x+8

here a = \sqrt{64x^{2} } =8x

b = \sqrt{8}= 2\sqrt{2}

2ab = 2*8x*2\sqrt{2} =32\sqrt{2}x

Now, we can see that the middle term should be 32\sqrt{2} x but in the question, it is given 49x

So, option B is true that - The x^2 coefficient does permit the factoring, but the x coefficient does not permit the factoring.

Answer:

17, 12, 7, 2, -3

Step-by-step explanation:

The range is just the y-axis values from that function. If you plug in the x values (the domain is the same thing) into the function, you get the y-values which is the range.

Mandy built a pyramid for her project on Egypt with a volume of 483
emmainna [20.7K]

Answer

We have,

Volume of pyramid = 4834 in³

Base area of the pyramid = ?

Assuming height of the pyramid = 20 in

We know that

Volume of pyramid =\dfrac{hlw}{3}  

           4834=\dfrac{20\time lw}{3}  

           l w = 725.1 in²

Hence, area of the base of the pyramid is equal to 725.1 in².

The population of a certain animal species you are studying decreases at a rate of 3.5% per year. Only 80 of the animals in the
balu736 [363]
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x  *  0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.

How do you determine whether a system of linear equations has no solutions, one solution, or infinitely many solutions?
Charra [1.4K]
The answer to this is

<span> If the lines are the same, the equations are dependent linear equations. Using the graph of y = x and x + 2y = 6, shown below, determine how many solutions the system has. Then classify the system as consistent or inconsistent and the equations as dependent or independent. The lines intersect at one point.</span>
