Answer 1
Answer:

Answer:

a). A = -2x² + 200x

b). Widths = 40 feet and 60 feet

Step-by-step explanation:

It is given that length of the fencing material = 200 feet

a). Peg wants to cover the vegetable garden from three sides with the given fencing material.

If length of the garden = l

and width of the garden = x

l + x + x = 200

l + 2x = 200

l = (200 - 2x) feet

Therefore, area of the garden = Length × width

A = (200-2x)* x

A = -2x² + 200x

b). Foe A = 4800 square feet,

4800 = -2x² + 200x

2x² - 200x + 4800 = 0

x² - 100x + 2400 = 0

x² - 60x - 40x + 2400 = 0

x(x - 60) - 40(x - 60) = 0

(x - 60)(x - 40) = 0

x = 40, 60 feet

Therefore, widths of Peg's garden will be 40 feet and 60 feet.

on monday a company stock close at a price of $30.80 per share on tuseday it increased by $1.20 per share on wenseday it fell by 6.25% on thursday it fell by another 4% and friday it increased by 2.5% what is the net change in the stock price from monday to friday

Answers

Tuesday:
30.80 + 1.20 = 32.00

Falling by 6.25% means it ends up being 93.75% of what it used to be (100% - 6.25% = 93.75%)

Wednesday:
32.00 * 0.9375 = 30

Thursday:
30 * 0.96 = 28.8

Friday:
28.8 * 1.025 = 29.52

Net change means you subtract to get the difference.

Net change = Final - initial
= 29.52 - 30.80
= -1.28

The stock fell $1.28

–81, 108, –144, 192, ...Which formula can be used to describe the sequence?
A.f(x) = –81(4/3)^x-1
B. f(x) = –81(-3/4)^x-1
C. f(x) = –81(-4/3)^x-1
D. f(x) = –81(3/4)^x-1

Answers

r = 108/-81 = -144/108 =192/-144 = -4/3
This is a geometric sequence with a common ratio (r) = -4/3
The nth term of a geometric sequence is given by tn = ar^(n-1) where a is the 1st term.
Therefore, the formular for the sequence is f(x) = -81(-4/3)^(x-1)
Answer: C [f(x) = -81(-4/3)^(x-1)]

Answer: C. f(x) = -81(-4/3)^(x-1)

A recipe for 1 lb of trail mix calls for 3.2 oz of cashews.How many ounces of cashews are needed to make 4 lb of trail mix?

A.
0.8 oz

B.
4.2 oz

C.
7.2 oz

D.
12.8 oz

Answers

D. Is the correct answer. Since 1 LB needs 3.2 OZ, and you need to make 4 LB, 3.2 x 4 = 12.8

Write the resultant of the two vectors as an ordered pair. <3, 6> and <5, –5>

Answers

Answer: The resultant of the two vectors as an ordered pair is given by

<8,1>

Step-by-step explanation:

Since we have given that

There are two vectors :

\vec{a}=<3,6>=3\hat{i}+6\hat{j}\n\n\vec{b}=<5,-5>=5\hat{i}-5\hat{j}

So, we need to find the "Resultant of the two vectors":

\vec{a}+\vec{b}=(3+5)\ha{i}+(6-5)\hat{j}\n\n\vec{a}+\vec{b}=8\hat{i}+\hat{j}

Hence, the resultant of the two vectors as an ordered pair is given by

Is it possible to write a sequence that is both arithmetic and geometric

Answers

It is not possible to write a sequence that is both arithmetic and geometric.
An arithmetic sequence is:
a0, a0 + d, a0 + 2d, a0 + 3d, ...

An geometric sequence is:
a0, a0r, a0r2, a0r3, ...

So if the two are equal, we have:
a0 = a0,
a0 + d = a0r,
a0 + 2d = a0r2,
a0 + 3d = a0r3,
...

This can only be true if d = 0 and r =1 and only for the first three terms. It's a trivial sequence with only three elements which can't be necessarily classified as a sequence.
