Stells [14]3 years ago

Answer:

Step-by-step explanation:

(a) p(2)=(2+2) (2+5) (2-4)

=4*7*-2

=-56

So this is not the polynomial

(b) p(2)=(4-4) (2+5) (2+5)

=0*7*7

p(5)=(10-4)(5+5)(5+4)

6*10*9

=540

So this is also not the polynomial

(c)p(2)=(6-2)(2-5)(2-4)

4*-3*-2

so this is also not the polynomial

(d)p(2)=(4-4)(2-3)(2+4)

p(5)=(10-4)(5-5)(5+4)

p(-4)=(-8-4)(-4-5)(-4+4)

so this is the polynomial

Answer:

210 in²

Step-by-step explanation:

Use the formula for area:

A = 1/2bh

Each triangle will have the area of:

A = 1/2*6*14 = 42 in²

Total amount of plywood will be:

42*5 = 210 in²

Find the distance between the origin and the point R = (9,7,8). The distance is: Ensure that you use at least 4 decimal place ac

gregori [183]

Answer:

The distance between the origin and the given point is 13.9283 units.

Step-by-step explanation:

The coordinates of origin are (0,0,0)

We are given a point R(9,7,80

The distance formula:

$\sqrt{(y_1 -x_1)^2 + (y_2 -x_2)^2 + (y_3 -x_3)^2}$ , where $(x_1, x_2, x_3)$ are coordinates of one point and $(y_1, y_2, y_3)$ are coordinates of other point.

Putting the values as:

$y_1 = 9, y_2 = 7, y_3 = 8\\x_1 =0, x_2 = 0, x_3 = 0$

We get d = $\sqrt{81 + 64 + 49}$

d = $\sqrt{194}$

d = 13.9283

Thus, the distance between the origin and the given point is 13.9283 units.

Pls help and show your work

Dmitriy789 [7]

Answer:

21. Vol. = L ^ 3

or, 27000 = L ^ 3

or, cube root undefr 27000 = L

Therefore, Edge length = 30 cm

22.

a. v = l ^ 3

or, 64000 = l ^ 3

or, cube root under 64000 = L

or, l = 40 cm

Also,

surface area = 6 a ^ 2

= 6 * 40 ^ 2

= 6 * 1600

= 9600 cm ^ 2 #
