The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models

the data in the table. A 2-column table with 5 rows. The first column is labeled time (seconds) with entries 0, 0. 5, 1, 2001. 5, 2. The second column is labeled height (feet) with entries 100, 96, 84, 65, 37. For which value of x would this model make the least sense to use? –2. 75 0. 25 1. 75 2. 25.

The given model would make the least sense to use for x=-2.75.

the given function is:

h(x)= -16x^2 +100

a quadratic relationship,

where

h is the height in feet

x is the time in seconds

<h3>what is kinetic energy?</h3>

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.

h(-2.75) = -16*(-2.75)^2+100 = -21\\

h(0.25) = -16*0.25^2 +100=99-0.25^2*16+100=99

h(1.75) = -16*1.75^2+100=51

h(25) = -16*2.25^2+100= 19

therefore, x=-2.75 this model would make the least sense to use

The combined area of two squares is 45 square centimeters.each side of one square is twice as long as the side of the other .wha
serg [7]
Formula of square area
a = s²
thus, area of the first square could be written as s₁² and area of the second square could be written as s₂²

First, write an expression in the form of equation system
An expression for "The combined area of two squares is 45 square centimeters" is:
⇒ s₁² + s₂² = 45 <em>(first equation)</em>
An expression for "Each side of one square is twice as long as side of the other" is:
⇒ s₁ = 2s₂ <em>(second equation)</em>

Second, solve the equation system by substitution method.
⇒ We could substitute 2s₂ to s₁ (second equation) in the first equation in order to find the value of s₂
s₁² + s₂² = 45
(2s₂)² + s₂² = 45
(2²)(s₂)² + s₂² = 45
4s₂² + s₂² = 45
5s₂² = 45
s₂² = 45/5
s₂² = 9
s₂² = 3²
s₂ = 3

⇒ Substitute the value of s₂ to the second equation in order to find the value of s₁
s₁ = 2s₂
s₁ = 2(3)
s₁ = 6

The length of each side of the larger square is 6 centimeters

A ladder 6.5 m long rests against a vertical wall. If the foot of the ladder is 2.5m from the foot of the wall find upto how muc
Burka [1]

Answer:

The ladder reaches a height of 6 m.

Step-by-step explanation:

Given that,

Height of the ladder, H = 6.5 m

The foot of the ladder is 2.5 m from the foot of the wall.

We need to find the height does the ladder reach. If we consider a triangle in which hypotenuse is 6.5 m, foot of the ladder is 2.5 m then we need to find the height of the ladder i.e.

H^2=b^2+h^2\\\\h^2=H^2-b^2\\\\h^2=(6.5)^2-(2.5)^2\\\\h=6\ m

The ladder reaches a height of 6 m.

What is the common difference for this arithmetic sequence?<br> 29, 42, 55, 68, ..
gregori [183]

Answer:

Common difference is 13 for this arithmetic sequence 29,42,55,68,...

Step-by-step explanation:

Given the arithmetic sequence 29,42,55,68,...

we have to find the common difference of the above sequence.

Common difference of arithmetic sequence is the difference between two successive terms. Therefore, to find common difference we take any pair of successive numbers, and subtract.

Common difference,

d=42-29=13

d=55-42=13

d=68-55=13

Hence, the difference between two successive terms is 3

∴ Common difference is 13
