In sunlight, a vertical yardstick casts a 1 ft shadow at the same time that a nearby tree casts a 15 ft shadow. How tall is the
kati45 [8]

Answer: A) 45 ft

Step-by-step

The yardstick is 3ft tall since 1 yard = 3ft. It is 3 times as tall as its shadow. The tree has a 15ft long shadow. The tree should also be 3 times as tall as its shadow. The tree is 15*3ft tall, so it is 45ft tall. I attached an image of the diagram I made.

The quadratic equation is
NemiM [27]

Answer:

(2,-9)

Step-by-step explanation:

Set the quadratic equal to zero.

y =  {x}^{2}  - 4x  -  5

Factor

(x - 5)(x + 1)

Set each of these factors to zero

x - 5 = 0

and

x + 1 = 0

x = 5

and

x =  - 1

Plot the midpoint of the two values.

( \frac{5 + ( - 1)}{2} ) = 2

So the middle term is 2 and the other terms are 5 and -1.

Now the vertex is

2 {}^{2}  - 4(2) - 5 =  - 9

So the vertex is

(2,-9)

A new restaurant is to contain​ two-seat tables and​ four-seat tables. Fire codes limit the​ restaurant's maximum occupancy to 7
Pavel [41]
Let t and f be the number to two and four seat tables respectively.

t+f=22, solve for t

t=22-f, then we are told that capacity must be less than or equal to 72 people.

2t+4f≤72, using t found above in this equation we get:

2(22-f)+4f≤72 perform indicated multiplication on left side

44-2f+4f≤72  combine like terms on left side

44+2f≤72  subtract 44 from both sides

2f≤28  divide both sides by 2

f≤14  Since f=integer

f=14, and since t=22-f

t=8

So they should purchase 14 four seat tables and 8 two seat tables.
