The base of a pyramid has n sides write an expression for the number of faces of the pyramid

1 answer:

6 0

A pyramid always have a number of slant triangles equal to the number of the sides of the base.

This means that a pyramid always have the number of face which is one more than the number of sides of the base.

Therefore, given that a pyramid has n number of sides of the base, the expression for the number of faces of the pyramid is given by

number of faces = n + 1.

A ball is launched straight up in the air from a height of 6 feet. Its velocity (feet/second) t seconds after launch is given by

german

Step-by-step explanation:

A ball is launched straight up in the air from a height of 6 feet. The velocity as a function of time t is given by :

f(t) = -32 t+285

Height of the ball is :

$h(t)=\int\limits{f(t){\cdot} dt}\\\\h(t)=\int\limits{(-32t+285){\cdot} dt}\\\\h(t)=-16t^2+285t+C$

C is constant. Here the ball is launched from a height of 6 feet. So,

$h(t)=-16t^2+285t+6$

At t = 2 s, $h(t)=-16(2)^2+285(2)+6=512\ m$

At t = 9 s, $h(t)=-16(9)^2+285(9)+6=1275\ m$

Between 2 s and 9 s, the ball's height changed is : 1275 - 512 = 763 m.

Consider two countries, A and B, whose respective industries produce goods A and B. Total world output of the good is given by Q

castortr0y [4]

Answer: hello your question is poorly written attached below is the complete question

answer :

a) 31.5

b) 24.5

Step-by-step explanation:

Total world output of good given ( Q ) = qA + qB

world demand ( P ) = 100 - Q

cost function for country A = cA (qA) = 8qA

cost function of country B = cB(qB) = 3qB

total world emission = 0.5Q

emission per unit good = 0.5

<u>a) Determine total world emissions when both countries compete in a Cournot fashion</u>

Q = 63

therefore Total world emission = 0.5 ( Q )

= 0.5 ( 63 ) = 31.5

attached below is the detailed solution

<u>b) Determine the total world emissions after Country A enacts a carbon tax</u>

Q = 49

Therefore Total world emission after tax = 0.5 ( Q )

= 0.5 ( 49 ) = 24.5

attached below is the detailed solution

Many food products are packaged in a variety of sizes. The list below gives the sizes and costs of fruit juice drinks at one sto

kicyunya [14]

The two sizes chosen for this item are a quart and one gallon.

The first one is advantageous because when it is desired that this be brought some place, it will not be very bulky and not heavy because among the given, this is the smallest. Also, one gallon can be chosen because it does serve many people at a relatively lower price than the other given.
