For this case we have the following expression:
y = (x + 3) ^ 2 + 53
We rewrite the expression:
y = (x ^ 2 + 6x + 9) + 53
We add the constant term:
y = x ^ 2 + 6x + 62
Answer:
The standard equation of the polynomial for this case is given by:
y = x ^ 2 + 6x + 62
option B

Oxford currently generates 45,000 tons of garbage per year. but the city is launching some recycling initiatives to bring that n

barxatty [35]

Answer:

-Exponential Decay

-Decay factor is (1-0.05)

Step-by-step explanation:

-Given that the number decreases by a defined rate each year from the initial size by 5%,

-This is an exponential decay function of the form:

$y=Ae^{-rt}$

Where:

$y$ is the quantity/size after time t

$A$ is the initial size

$r$ is the rate of decay

-Our function can the be written as

$y=45000e^{-0.05t}$

Hence, the decay rate/factor is 0.05

#Alternatively

The exponential decay can be of the form:

$y=ab^x$

Where:

y is the size at time x, a is the initial size, x is time and b is the decay factor.

b is of the form $b=(1-r),\ \ r=decay\ rate$

$y=ab^x\\\\y=45000(1-0.05)^x$

Hence, the decay factor is (1-0.05)

The officer stepped off 20 paces from E to G. If his pace is 2 1/2 feet long. How wide was the river?

Sergeeva-Olga [200]

Answer:

The wide of river is $50\ ft$

Step-by-step explanation:

In this problem we know that

Triangles DEG and DEF are congruent by ASA (Angle-Side-Angle) Congruence

therefore

EG=EF

$EG=20*(2\frac{1}{2})=20*\frac{5}{2}=50\ ft$

Help! Please. I don’t know what I did wrong.

Debora [2.8K]

Answer:

1320, permutation

Step-by-step explanation:

There are 12 members

Pick a president

We have 12 choices

Now there are 11 people left to pick from

now pick a vp

We have 11 choices

Now there are 10 people left to pick from

now pick a secretary

We have 10 choices

12*11*10 = 1320

This is a permutation since it matters who is president, vp and secretary

<u><em>Answer: </em></u>

#9: 5

#10: -2

#11: -1.5

<em><u>Step-by-step explanation:</u></em>

<em><u>#9:</u></em> 3,8,13,18,23,(28),(33),(38),.. <em>Go up by 5 each time, so the common difference is </em><u><em>5</em></u><em>.</em>

<u><em>#10:</em></u> 11,9,7,5,3,(1),(-1),(-3),... <em>Go down </em><em>(-)</em><em> by 2 each time, so the common difference is </em><u><em>-2</em></u><em>.</em>

<u><em>#11:</em></u> 3, 1.5, 0, -1.5, -3, (-4.5), (-6), (-7.5),... <em>Go down </em><em>(-) </em><em>by 1.5 each time, so the common difference is </em><u><em>-1.5</em></u><em>.</em>
