Answer 1
Answer:

Step-by-step explanation:

this is only asking about the functional values.

in what intervals are the functional values going up (when increasing x from left to right), and in what intervals is the functional value going down (again, when increasing x from left to right) ?

and so we see in the graph,

it is increasing (y-values are going up) in

(-infinity, -1], (2, +infinity)

it is decreasing (y- values are going down) in

(-1, 2]

please consider the used types of brackets.

"(", ")" means the corresponding interval end is NOT included.

"[", "]" mags the corresponding interval end is included.

"infinity" is only a concept and not a value, so it can never be included.

and I wanted the intervals to have no overlap. so, I included "-1" in one and excluded it in the connecting interval. the same for "2".

but if your teacher prefers to have the interval ends overlapping, then please change these brackets to "["as needed. it all depends on what your teacher defined for you.

See explanation below

Step-by-step explanation:

We are going to transform the given phrase to an equivalent algebraic expression, let's x be a number:

a) The product of -12 and a number (we have to multiply)

(-12)x = -12x

b) The quotient of -12 and a number (quotient means division)

(-12)/(x)

c) Twice the sum of -12 and a number (we're going to sum up -12 and a number and then multiply by 2)

2(-12 + x)

d) The sum of -12 and twice a number (we're going to sum up -12 and the double of the number)

-12 + 2x

if the quanity demanded of soda decreases by 5 percent when the price of soda rises by 100 percent what is the price elasticity of demand for soda

Answers

Price elasticity of demand is calculated as the ratio of change in demand to the ratio of change in price. So if the demand changes -5% when the price changes 100%, the PED = -5% / 100% = -0.05. Most good have a PED < 0, since demand typically decreases when the price is increased.

The average (A) of two numbers, m and n, is given by the formula A = m+t/2 . Findthe average of the two numbers 36 and 72.
The solution is

Answers

Answer:

54

Step-by-step explanation:

Formula for average A of two numbers m and n is:

A=(m+n)/(2)

Substitute the value m=36 and n=72

A=(36+72)/(2)

This is equivalent to:

A=(108)/(2)

The average is:

A=54

Assume you drop a rock from a cliff which is 5000 feet above the ground. The distance in feet, y, of the rock below the cliff at the time t seconds after it was dropped is given by the equationY=-1/2gt^2

Answers

Answer:

Step-by-step explanation:

Given that height of cliff H = 5000 ft

You drop rock from cliff and the distance of rock below the cliff at time,t is given by:

y= -(1)/(2) gt^(2)

Q1. How far below the cliff is the rock 7 seconds after it dropped ?

Ans. Here, t=7 seconds

By using formula provide, g=32.18 ft{tex]s^(-2)

y=- \frac{1}{2} × 32.17 × (7)^{2}[/tex] = 788.165 ‬ft

Note: Negative sign shows the direction and 240.345 is magnitude

Therefore, Rock is 788.165‬ ft from Cliff

Q2. How far is the rock from the bottom 7 seconds after it dropped ?

By using formula provide,

Ans. After 7 seconds, Rock is 788.165‬ ft from Cliff

Therefore, Rock is 5000-788.165‬ = 4,211.835 ft from bottom

Q3. When will rock hit the bottom?

Ans. Height of cliff H= 5000 ft

Using formula provided, g=32.18 fts^(-2)

y = -(1)/(2) gt^(2)

-5000 = - (1)/(2) 32.18 × t^(2)

t^(2) = (5000×2)/(32.18)

t^(2) = 311.13876

t = 17.6s

Q4. The Velocity of the rock at impact?

Ans. Velocity is given as V= g×t

By using formula, We get

V= 32.14 × Total time to reach ground

V= 32.14 × 17.6 = 565.66 ft/s
