Distribute and add like terms
-(6a³-3a+8)=-6a³+3a-8

now add
3a²+4a-6-6a³+3a-8
regroup
-6a³+3a²+4a+3a-6-8
-6a³+3a²+7a-14
dat is expanded and compacted

Maslowich

In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

$d= \sqrt{12h}$

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:

$d= \sqrt{12*350}=64.81$

Therefore, the approximate distance to the horizon for the person will be 64.81 km

I need help finding surface area for both of these shapes with work

Alex73 [517]

For the base of the shape all you need to do is multiply 25x25=625ft²

then for the 4 sides you need to multiply 25x32=800ft²

and because there are 4 sides you multiply 800x4=3200

so now you add 3200 with 625 (3825) and there's your area

The length of 2 sides of a triangle are 12 inches and 4 inches. Which is the third side?

Westkost [7]

Answer:

Let x = the third side

In a triangle, the sum of any 2 sides must be larger than the third side.

I believe this is called the triangle inequality theorem.

We can construct 3 inequalities to obtain the range of values for the third side.

(Inequality #1) 12 + 4 > x

16 > x

(Inequality#2) 12 + x > 4

x > -8 (we can discard this ... we know all sides will be positive)

(Inequality #3) 4 + x > 12

x > 8

So when we combine these together,

8 < x < 16

X (the third side) must be a number between 8 and 16. but not including 8 and 16

Answer:

The degrees of freedom for this sample are 27.

The sample size to get a margin of error equal or less than 0.3656 is n=4450.

Step-by-step explanation:

The degrees of freedom for calculating the value of t are:

$df=n-1=28-1=27$

With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.

The sample size to get a margin of error equal or less than 0.3656 can be calculated as:

$MOE=t\cdot s/\sqrt{n}\\\\n=\left(\dfrac{t\cdot s}{MOE}\right)^2=\left(\dfrac{2.052\cdot 11.8841}{0.3656}\right)^2=66.7^2\\\\\\n=4449.13\approx4450$
