Step-by-step explanation:

we know,

volume of pyramid = 1/3 × base area × height

so,

→ 1/3 × 120 × 9

→ 40 × 9 = 360 ft

so the volume of the pyramid is 360 ft².

base area = length × slant height

so, 12 × 10 = 120

hope this answer helps you dear....take care and may u have a great day ahead dear !

If the volume of a sphere is 36 pi cubic units, what is the radius?

Radda [10]

Answer:

3 units

Step-by-step explanation:

Hello

The sphere volume is:

(4/3)*Pi*r^3

then

36 = (4/3)*Pi*r^3

36/[(4/3)*Pi] = r^3

8,5 = r^3

r = 3

Factorise x^2-y^2-2x+6y-8

Talja [164]

X^2 - y^2 - 2x + 6y - 8
= (x^2 - 2x + 1) - (y^2 - 6y + 9) - 8 - 1 + 9 
= (x - 1)^2 - (y - 3)^2 
= [(x - 1) - (y - 3) ] [(x - 1) + (y - 3)] 
= (x - 1 - y + 3) ( x - 1 + y - 3) 
= (x - y + 2) (x + y - 4)

is vector v with an initial point of (-5,22) and a terminal point of (20,60) equal to vector u with an intintal point of (50,120

marta [7]

Answer:

Yes, vectors u and v are equal.

Step-by-step explanation:

We need to check whether vectors u and v are equal or not.

If the initial point is $(x_1,y_1)$ and terminal point is $(x_2,y_2)$ , then the vector is

$Vector=(x_2-x_1)i+(y_2-y_1)j$

Vector v with an initial point of (-5,22) and a terminal point of (20,60).

$\overrightarrow v=(20-(-5))i+(60-22)j$

$\overrightarrow v=25i+38j$ ..... (1)

Vector u with an initial point of (50,120) and a terminal point of (75,158).

$\overrightarrow u=(75-50)i+(158-120)j$

$\overrightarrow u=25i+38j$ .... (2)

From (1) and (2) we get

$\overrightarrow u=\overrightarrow v$

Therefore, vectors u and v are equal.
