Answer:

Undefined

Step-by-step explanation:

There is no slope it's a vertical line, think of a snowboarder, a horizontal line is y=0, this is zero fun, but going straight down a cliff, he would be yelling undefined.

find the volume of the cone. either enter exact answer in terms of pi or use 3.14 for pi and round your final answer to the near

SCORPION-xisa [38]

Answer:

$6\pi u^3 = 18.8u^3$

Step-by-step explanation:

the information we have is:

the radius of the circle in the base: $r=3u$ (u for units)

and the height of the cone: $h=2u$

to find the volume we need the formula for the volume of a cone:

$V=\frac{\pi r^2h}{3}$

where r is the radius and h is the height.

Substituting the known values to find the volume:

$V=\frac{\pi (3u)^2(2u)}{3} \\\\V=\frac{\pi (9u^2)(2u)}{3}\\ \\V=\frac{18\pi u^3}{3}\\ \\V=6\pi u^3$

the volume in terms of $\pi$ is $6\pi u^3$

and if we substitute the value of pi: $\pi=3.14$ we get:

$V=6(3.14)u^3\\V=18.8u^3$

Show that X^2-8x+20 can be written in the form (x-a)^2+a

svlad2 [7]

Answer:x^2 + 8x + 20

a = 1

b = 8

c = 20

Discriminant = b^2 - 4ac

=> 8^2 - 4(1)(20)

=> 64 - 80

=> -16

As -16<0

So, equation has no real roots

The average weight of 10 boys is 77.0 pounds. If the

n200080 [17]

Answer:

68 pounds.

Step-by-step explanation:

Find the total weight when there are 10 boys and when there are 9 boys then calculate the difference.

I'll let x = total weight.

$\frac{x}{10}=77\\(10)\frac{x}{10}=77(10)\\x=770\\\\ \frac{x}{9}=78\\(9)\frac{x}{9}=78(9)\\x=702\\\\ 770-702=68$

Therefore, the youngest boy weighs 68 pounds.

In the diagram, ATPR~AXPZ. Find the length of side PZ.

xenn [34]

Answer:

PZ = 15

Step-by-step explanation:

Similar Triangles

Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.

It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.

Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:

$\displaystyle \frac{15}{9}=\frac{25}{PX}$

PX and PZ are congruent, thus:

$\displaystyle \frac{15}{9}=\frac{25}{PZ}$

$\displaystyle PZ=25*\frac{9}{15}$

Calculating:

PZ = 15

For this,we need to know what's Middle splitting method

In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as px + qx and get desired factors by grouping the terms.

Step-by-step explanation:

$9x {}^{2} - 24x + 16 \\ = > 9x {}^{2} - 12x - 12x + 16 \\ = > 3x(3x - 4) - 4(3x - 4) \\ = > (3x - 4)(3x - 4) \\ so... \\ x = eitherway \: 4$

i.e

Alpha= Beta = 4
