Answer:

$5x^{3} -3x^{2}-5x+3$

Step-by-step explanation:

we have

$(5x^2 + 2x - 3)(x - 1)$

Applying the distributive property, group and combine like terms

$(5x^2 + 2x - 3)(x - 1)=5x^{2} *x-5x^{2}*1 +2x*x-2x*1-3*x+3*1\\ \\=5x^{3} -5x^{2}+2x^{2} -2x-3x+3\\ \\=5x^{3} -3x^{2}-5x+3$

Write the polynomial in standard form. Then name the polynomial on its degree and numbers of terms. 8-4x^2+10x^2+2x

mojhsa [17]

8-4x^2+10x^2+2x
8+6x^2+2x
6x^2+2x+8

This is a quadratic equation since it has three terms. Now, a=6 (that is, a≠0) and therefore, it is a quadratic trinomial equation.

The correct answer is C.)

Is the answer A.-6y=- 12 B.-6y=12 C. -2y=-12 D.2y=12

polet [3.4K]

Answer:

The answer would not be A. It is B

Step-by-step explanation:

Because you are subtracting the equations, on the right side of the equal sign, you are subtracting -5 from 7. This is 7-(-5), which is equal to 7+5=12, not -12.

The diameters of bolts produced by a certain machine are normally distributed with a mean of 0.35 inches and a standard deviatio

Fiesta28 [93]

Answer:

15.87%

Step-by-step explanation:

Notice that the mean of 0.35 inches with a standard deviation of 0.01 gives you when you add (to the right of the distribution), exactly 0.36. Since you want to find the probability (or percentage) of the bolts that have diameter LARGER than 0.36 in, that means you want to estimate the area under the Normal distribution curve from 0.36 to the right). See attached image.

We can use the tables of Z distribution for that, or the standard normal tables:

P(x>0.36) = P(z>(0.36-0.35)/0.01) = P(Z>1) = 0.1587 = 15.87%
