Answer:  The required factored form of the given expression is 2(x+3)(x^2+5).

Step-by-step explanation:  We are given to factor the following cubic expression completely :

E=2x^3+6x^2+10x+30~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

First we will take 2 common as it is multiplied to all the terms of the expression and then we will try to factorize the rest of the expression.

The factorization of expression (i) is as follows :

E\\\\=2x^3+6x^2+10x+30\\\\=2(x^3+3x^2+5x+15)\\\\=2(x^2(x+3)+5(x+3))\\\\=2(x+3)(x^2+5).

Thus, the required factored form of the given expression is 2(x+3)(x^2+5).

The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. a. Find the pro
Bogdan [553]

Answer:

Step-by-step explanation:

Let X be the length of pregnancy.

X is N(268, 15)

a) Prob of pregnancy lasting 307 days or longer

= P(X>307) = P(Z>\frac{307-268}{15} )\\=P(Z>2.6)\\

=0.5-0.4953

=0.0047

b) Lowest 2% is 2nd percentile

Z=-2.55

X score = 268-2.55(15)

= 229.75 days

If length of days >230 days then it is not premature.

F(4) = ______<br> If g(x) = 2, x = _____
disa [49]

Answer:

<h2>f(4) = -10 </h2><h2> </h2><h2>x = 0 </h2>

Step-by-step explanation:

From the graph attached,

For x = 4,

Value of the function will be,

f(4) = y value at x = 4

f(4) = -10

Similarly, for y = g(x) = 2,

x value of the function will be,

x = 0

For which g(0) = 2

Therefore, for x = 0 value of the function will be 2.

g(0) = 2

Ke Shawn is placing a right triangle in the coordinate plane. He knows that the longer leg is twice the length of the shorter le
Artist 52 [7]

the 3rd vertex is on the x axis line which means Y =0

 since the longer leg is twice as long as the shorter leg and the length of the shorter leg is a, then twice the length would be 2a ( 2 times a)


 so the 3rd vertex is (2a,0)
