Find a number C such that the polynomial p(x)= -x+4x^2+Cx^3-8x^4

Ksenya-84 [330]

Answer:

C = 2

Step-by-step explanation:

$p(x)= -x+4x^2+Cx^3-8x^4 \\ \\ \because \: given \: polynmial \: has \: zero \: at \: \\x = \frac{1}{4} \\ \\ \implies \: p\bigg(\frac{1}{4} \bigg) = 0...(1) \\ \\ plug \: x = \frac{1}{4} \: in \: p(x) \: we \: find \\ \\ p \bigg(\frac{1}{4} \bigg) = - \frac{1}{4} + 4 {\bigg(\frac{1}{4} \bigg)}^{2} + c {\bigg(\frac{1}{4} \bigg)}^{3} - 8 {\bigg(\frac{1}{4} \bigg)}^{4} \\ \\ 0 = - \frac{1}{4} + \cancel 4 \times {\frac{1}{\cancel{16} } } + c {\bigg(\frac{1}{64} \bigg)} - \cancel 8 \times \frac{1}{\cancel{256} } \\ \\0 =\cancel{ - \frac{1}{4}} + \cancel {{\frac{1}{4} }} + c {\bigg(\frac{1}{64} \bigg)} - \times \frac{1}{32} \\ \\0 = c {\bigg(\frac{1}{64} \bigg)} - \frac{1}{32} \\ \\c {\bigg(\frac{1}{64} \bigg)} = \frac{1}{32} \\ \\ c = \frac{1}{32} \times 64 \\ \\ c = 2$

For all positive integers n, let *n* equal the greatest prime number that is a divisor of n. What does *10*/*12* equal?

artcher [175]

9514 1404 393

Answer:

5/3

Step-by-step explanation:

The prime factorizations are ...

10 = 2·5

12 = 2·2·3

Then *10* = 5 and *12* = 3, so *10*/*12* = 5/3.

Please answer this question I need it i. Vertex and standard form.

Brums [2.3K]

Equation :

This parabola is facing downwards and highest point of the parabola is it's vertex.

Highest point is (-2,2)

so the vertex is (-2,2)

The graph is passing through (-1,0)

Equation in vertex form is

$y = a(x - h) {}^{2} + k$

$0 = a( - 1 + 2) {}^{2} + 2 \\ 0 =a (1) {}^{2} +2 \\ 0 = a + 2 \\ a = - 2$

Substitute back in Equation

$y = - 2(x + 2) {}^{2} + 2$

the graph has two x intercepts -1 and -3

that means (x+1) and (x+3) are the factors

multiply factors to get the equation in standard form

$-2(x + 1)(x + 3) = 0 \\ -2(x {}^{2} + x + 3x + 3) = 0 \\ -2( x {}^{2} + 4x + 3) = 0$

-2x^2-8x-6=0

What's the answer please

siniylev [52]

The answer to this would be Point H because, you have to look in between points FB, which gives you the choices of G, H, L, the most logical answer for this would be point H because its in the middle of points FB. Hope my answer helps
