This question has this set of answer choices:

a) when the plane cuts three faces of the cube, separating one corner from the others

b) when the plane passes through a pair of vertices that do not share a common face

c) when the plane is perpendicular to the base and intersects two adjacent vertical faces

d) when the plane makes an acute angle to the base and intersects three vertical faces

e) not enough information to answer the question

The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others

You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.

You usually buy a 5.45.4 ounce bottle of lotion. There is a new bottle that says it gives you 20%20% more free.
valentina_108 [34]

Answer: The required equation is,

x = \frac{120\times 5.4}{100}

Step-by-step explanation:

Let x be the size of the larger bottle,

Since, the size of smaller bottle of lotion = 5.4 ounces,

According to the question,

The larger bottle gives 20% more free lotion,

The size of the larger bottle = The size of smaller bottle of lotion  + 20 % of the size of smaller bottle of lotion

= 120 % of the size of smaller bottle of lotion

= 120 % of 5.4

=\frac{120\times 5.4}{100}

\implies x = \frac{120\times 5.4}{100}

Which is the required equation that could be used to find the size of the larger bottle.

DedPeter [7]
By plugging (k-2) in t, we can write that
f(k-2)=3(k-2)^{2}-2=3(k^{2}-4k+4)-2=3 k^{2}-12k+12-2=3 k^{2}-12k+10

A plane is flying at 1000 meters above the ground and fires a laser 60 degrees of of straight down. what is the distance the lig
juin [17]

Answer:

Step-by-step explanation:

The distance the light traveled to the ground is the range of the plane expressed as:

R = U*√2H/g

U is he velocity

H is the max height

g is the acc. due to gravity

Let us get U first using the formula

H = u²sin²Ф/2g

1000 = u²sin²60/2(9.81)

1000*19.62 = 0.8660u²

19620 = 0.8660u²

u² = 19620/0.8660

u² = 22655.88

u = √22655.88

u = 150.52m/s

Next is to get the range

R = 150.52√2(1000)/9.81

R = 150.52 √2000/9.81

R = 150.52√203.87

R = 150.52*14.28

R = 2149.16m

Hence the distance the light traveled to the ground is 2,149.16m
