Answer:
1 + 14x + 84x^2 + 280x^3 or
128x^7 + 448x^6 + 672x^5 + 560x^4.
(see explanation),
Step-by-step explanation:
They are 1^7 + 7C1 1^(7-1)(2x) + 7C2 1^5 (2x)^2 + 7C3 1^4 (2x)^3
= 1 + 14x + 21* 4x^2 + 35*8x^3
= 1 + 14x + 84x^2 + 280x^3
If you require the answer in descending degrees of x by a similar method the answer is:
128x^7 + 448x^6 + 672x^5 + 560x^4.

Write a story problem that includes both integers −8 and 12.
Answer:
Sea level is 0 meters. A cliff by the ocean is 12 meters above sea level. Around that area, the seafloor is 8 meters below sea level. How many meters is the top of the cliff to the seafloor?
How to solve:
8 below zero is -8
The expression 12 - (-8) is the same as the expression 12 + 8
12 + 8 = 20
20 meters

Calculate the acceleration of a moving object, given that the object is 500 g and has a a force of 6.5 n
Hello!
[tex]\large\boxed{a = 13m/s^{2}}[/tex]
Use the equation F = m · a to solve where:
F = total force (N)
m = mass (kg)
a = acceleration (m/s²)
We are given the force and mass, so we can plug these values into the equation to solve.
However, mass is used in kilograms, so we must convert from grams to kilograms:
1 kg = 1000 grams
Convert using dimensional analysis or proportions:
[tex]500 g* \frac{1 kg}{1000g} = 0.5kg[/tex]
Plug in the force and mass to solve:
6.5 = 0.5(a)
Divide both sides by 0.5 (Multiply by 2)
a = 13 m/s²

What is the meaning of the point shown on this graph?
(graph is given below)
Melissa's garden has an area of 24 feet2 when the length is 40 feet.
Melissa's garden is 40 feet wide when the length is 24 feet.
Melissa's garden has an area of 40 feet2 when the length is 24 feet.
Melissa's garden has dimensions 40 feet by 24 feet.
Answer:
Melissa's garden has an area of 40 feet² when the length is 24 feet
Step-by-step explanation:
The point, (24, 40), shown on the graph suggests that, Melissa's garden with a length of 24 ft, has an area of 40 ft².
The 24 is on the x-axis which is representing length of the garden. While 40 is on the y-axis represents the area of the garden.
The foot of a 24 ft ladder is placed 6 ft from the base of a building, determine at what height the
ladder rests on the building.
Answer:
12.6491106
Step-by-step explanation:
With respect to the angle formed by the bottom of the
ladder with the ground
cos T = 6/14 = 3/7
T = inverse-cosine(3/7) = 64.623006647 degrees
sin(64.623006647) = h/14
h = 14*sin(64.62300647) = 12.6491106

Mason was ordering the following rational numbers in math class: -3.3, -15, -8 8/9.
a. Order the numbers from least to greatest.
b. List the order of their absolute values from least to greatest.
c. Explain why the orderings in parts (a) and (b) are different.
Answer:
a) -15, -8, -3.3, 8/9
Step-by-step explanation:
b) 8/9, -3.3(And I say its -3.3, because you need to write it in its original form.), so far its 8/9, -3.3, -8, -15.
c) Because the absolute value is the positive value of that number. (i.e, -3 is 3 places away from 0, so it's absolute value would be 3.)
If you rotate point (4, 2) 90° and 180° about the origin, how do the x- and
y-coordinates change?
Answer:
(4, 2) to (-2, 4) to (-4, -2).
Step-by-step explanation:
This 90 degree rotation depends on the direction of the rotation. I'm assuming clockwise here.
So (4, 2) rotated 90 degrees puts the point at (-2, 4).
Another 90 degrees (therefore total 180 degrees), and we get to (-4, -2).

Answer:
She wants 200 shirts
Each shirt costs $5
200 x 5 = 1000
200 shirts cost $1000
She has $350
$1000 - $350 = $650
She will need to raise another $650 to buy 200 shirts.

What is the value of cos theta given that (- 5, - 4) is a point on the terminal side of theta ?
Answer:I believe it's -5√41/41
Step-by-step explanation:
The value of [tex]cos\theta[/tex] will be [tex]-0.7813[/tex].
If the point [tex](-5.-4)[/tex] were rotated around the origin, it would form a circle of radius [tex]r[/tex]. Also, if the point were projected to the x-axis, a right-angled triangle would be formed. Then, the value of [tex]cos\theta[/tex], could be obtained by the formula
[tex]cos\theta=\dfrac{x}{r}[/tex]
where
[tex]x=\text{the side of the triangle opposite the reference angle of }\theta\\r=\text{the radius of the circle}[/tex]
From the point on the terminal side
[tex](x,y)=(-5,-4)[/tex]
we can directly get the value of [tex]x[/tex]. But we need to calculate the value of [tex]r[/tex].
To calculate the value of [tex]r[/tex], make use of Pythagoras theorem
[tex]r=\sqrt{x^2+y^2}\\=\sqrt{(-5)^2+(-4)^2}\\=\sqrt{25+16}\\\approx6.4[/tex]
We can now proceed to find the value of [tex]cos\theta[/tex], since we have the values of [tex]x[/tex], and [tex]r[/tex]. Therefore,
[tex]cos\theta=\dfrac{x}{r}\\\\=\dfrac{-5}{6.4}\approx-0.7813[/tex]

. If a landfill has a density of 1,200 pounds per cubic yard, what would be the volume required for 15- years worth of MSW to the nearest cubic yard
Here is the full data for the question.
Each person in the state of Texas generate roughly 7.5 pounds of municipal solid waste each day. Of this amount, roughly 35 percent of the waste is currently recycle in Texas. Studies have shown that the maximum amount of waste that could be realistically recycled or otherwise diverted from the landfill is 50 percent.
(NOTE: for tons, use I ton -2,000 pounds unless otherwise specified)
11. For a community/service area of 200,000 people, calculate the amount:
Total MSW each year, in pounds? ? Tons?
II. Total MSW currently recycled each year, in pounds? Tons?
III Amount of the MSW that could realistically be diverted from the landfill if recycling was maximized to the nearest pound.
12. Using the current recycling rate, calculate the amount of MSW sent to a landfill over 15 years period to the nearest pound.
13. If a landfill has a density of 1,200 pounds per cubic yard, what would be the volume required for 15- years worth of MSW to the nearest cubic yard?
Answer:
Step-by-step explanation:
11)
I) The amount of total MSW generated per day in pounds is = 1,500,000 Pounds
The total MSW generated per day in tons is = 750 Tons
The amount of the total MSW generated per year in pounds will be:
= 1,500,000 × 365
= 547,500,000 Pounds
The amount of the total MSW generated per year in tons is
= 750 × 365
= 273,750 Tons
II)
The amount of the total MSW currently recycled per day is pounds
= 1,500,000 × (35/100)
= 525,000 Pounds
Total MSW currently recycled per day in tons is
= 750 × 35/100
= 262.5 Tons
The amount of the total MSW currently recycled per year in pounds is
= 525,000 × 365
= 191,625,000 Pounds
The amount of the total MSW currently recycled each year in tons is
= 262.5 × 365
= 95812.5 Tons
III) The required amount of MSW which could realistically be diverted from the landfill suppose that the recycling was maximized (for each person) is
= 7.5 × (50/100)
= 3.75 Pounds
≅ 4 Pounds
The required amount of MSW which could realistically be diverted from the landfill suppose recycling were maximized (for the total population) is:
= 1,500,000 × (50/100)
= 750,000 Pounds
12)
Applying the current rate of recycling, the amount of MSW sent to landfill over a 15 year period (for each person) is:
= 7.5 × (100-35)/100
= 4.875 Pounds each day
= 4.875 × 365 × 15
= 26690.625 Pounds/ 15 years/person
≅ 26,691 Pounds/ 15 years/person
For 1 year period:
By applying the current rate of recycling, the required amount of MSW sent to landfill over (for total population) is:
= 547,500,000 × (100-35)/100)
= 355,875,000 Pounds
For 15 years period:
By applying the current rate of recycling, the amount of MSW sent to landfill (for total population) is:
= 355875000 × 15
= 5,338,125,000 Pounds
13)
The volume required for the landfill for 15 years worth of MSW is:
= 5,338,125,000/1,200
= 4,448,437.5 Cubic yard
≅ 4,448,438 Cubic yard
