Answer:

The answer is C.

Step-by-step explanation:

Recall that as consequence of the Fundamental Theorem of Algebra, a polynomial of n-th degree has n complex roots (some roots, or all of them, can be real).

Now, as we have a polynomial of degree 5, it has 5 roots. From the statement we know that its graph has three intercepts with the X-axis, which is equivalent to the existence, at least, of three real roots. Moreover, we know that the multiplicity of each root is one. Then, we have exactly three real roots.

The above deduction means that there are other two roots, and those must be complex.

Answer: C

<u>Step-by-step explanation:</u>

Degree of 5 means there are 5 roots.

If 3 roots are real, then there are 2 remaining - which must be imaginary.

Hello please help me with this I need an answer immediately thank you so much see image

For this case, we know that:

$PA = PB$

Then, by Pythagorean theorem (right triangle on the right) we have:

$CP ^ 2 = CB ^ 2-PB ^ 2$

So, again using the Pythagorean theorem (right triangle on the left) we have:

$CA ^ 2 = CP ^ 2 + PB ^ 2$

Substituting values:

$CA ^ 2 = (CB ^ 2-PB ^ 2) + PB ^ 2$

Rewriting:

$CA ^ 2 = CB ^ 2$

$CA = CB$

$CA = 15$

Answer:

The value of CA is given by:

$CA = 15$

A factory inspector found 3 defective microchips out of a total of 750

Y_Kistochka [10]

Answer:

Option B

Step-by-step explanation:

Proportion of number of defective pieces to the number of microchips in a batch can be represented by the ratio = $\frac{\text{Number of microchips not in good condition}}{\text{Total numbers of microchips}}$

If 3 microchips are defective in a batch of 750 microchips,

Proportion = $\frac{3}{750}$

If 'x' chips are defective in a batch of 10000 microchips,

Proportion = $\frac{x}{10000}$

If both the proportions are equal,

$\frac{3}{750}=\frac{x}{10000}$

Therefore, Option B will be the answer.
