Step-by-step explanation:

Hey there!

Given;

f(x)= 5x^2+12x-9.

Now, do mid-term factorization.

f(x)= 5x^2 + (15-3)x-9

= 5x^2+15x-3x -9

= 5x(x+3) -3(x+3)

= (5x-3)(x+3)

Therefore the answer is option C.

Hope it helps..

In the upcoming election for governor, the most recent poll, based on 900 respondents, predicts that the incumbent will be reele

Dmitriy789 [7]

Answer:

405

Step-by-step explanation:

From the given information, we have 900 respondent.

The poll predicts that the incumbent will be reelected with 55 percent of the votes.

This implies that (100-55=45) percent of the respondents would not vote for the current governor or indicated that they were undecided.

Out of 900 respondents, we have

$\frac{45}{100} \times 900$

$= 45 \times 9 = 405$

would not vote for the current governor or indicated that they were undecided.

Find the equation of the plane passing through the points

erica [24]

Extract the normal vectors from the given planes:

$-2x+y+z+2=0\implies\vec n_1=(-2,1,1)$

$x+y-3z+1=0\implies\vec n_2=(1,1,-3)$

(which are unique up to their signs, meaning either $\vec n_1$ or $-\vec n_1$ are valid choices for the normal vector)

The third plane must be perpendicular to both these given planes, which means it would be parallel to both $\vec n_1$ and $\vec n_2$ , which in turn means its own normal vector $\vec n_3$ should be perpendicular to both $\vec n_1$ and $\vec n_2$ .

Enter the cross product:

$\vec n_3=\vec n_1\times\vec n_2=(-4,-5,-3)$

or (4, 5, 3), which also works.

The given plane passes through (-1, 1, 4), so its equation is

$(x+1,y-1,z-4)\cdot\vec n_3=0$

Simplify:

$(x+1,y-1,z-4)\cdot(4,5,3)=0$

$4(x+1)+5(y-1)+3(z-4)=0$

$\boxed{4x+5y+3z=13}$
