anybody know the answer?
Answer:
Step-by-step explanation:
You can read f(x) to mean y. y is above the x axis between -2 and - 6. To put it more formally,
-6 <x <-2
Why don't you use ≤ ?
It's because where is f(x) positive? 0 is not a positive value,, so you cannot use the endpoints.
Using euler's formula how many edges does a polyhedron with 7 faces and 7 vertices have
Answer:
12 Edges
Step-by-step explanation:
Top one is right but had 2 stars for some reason. 12 Edges is the answer. (Just did it btw)
Edges of a polyhedron are 12.
What is polyhedron?"Polyhedron is a three dimensional solid shape with a certain number of faces, edges and vertices.
If the number of faces and the vertex of a polyhedron are given, we can find the edges using the polyhedron formula. This formula is also known as ‘Euler’s formula’."
F + V = E + 2
Here,
F = Number of faces of the polyhedron
V = Number of vertices of the polyhedron
E = Number of edges of the polyhedron
Given
Number of Faces (F) = 7
Number of Vertices (V) = 7
For any polyhedron,
Euler's Formula:
F + V - E = 2
⇒ 7 + 7 - E = 2
⇒ 14 - E = 2
⇒ E = 14 - 2
⇒ E = 12
Number of Edges (E) = 12
Hence, Edges of a polyhedron are 12.

This pool has a deep end and a shallow end.The pools perimeter is 70 ft.Hiw wide is the deep end,d?
Work Shown:
L = d+9 = length along the horizontal
W = 10 feet = width along the vertical
P = 2(L+W) = perimeter of rectangle = 70 feet
70 = 2(d+9+10)
70/2 = d+19
35 = d+19
d+19 = 35
d = 35-19
d = 16
The deep end is 16 feet wide

[tex] {y}^{3} + x {e}^{4} = 3 {x}^{2} - 10[/tex]
introduce dy/dx :
[tex] \frac{d( {y}^{3} + x {e}^{4} ) }{dx} = \frac{d( {3x}^{2} - 10) }{dx} \\ \\ 3 {y}^{2} \frac{dy}{dx} + {e}^{4} = 6x - 0 \\ \\ {3y}^{2} \frac{dy}{dx} = 6x - {e}^{4} \\ \\ { \boxed{ \boxed{\frac{dy}{dx} = \frac{6x - {e}^{4} }{ {3y}^{2} } }}}[/tex]
Solve the equation for j
jr+se=jb+f
Hello there!
We are given the equation:
[tex] \displaystyle \large{jr + se = jb + f}[/tex]
We are going to isolate j. First, subtract both sides by jb.
[tex] \displaystyle \large{jr + se - jb = jb - jb+ f} \\ \displaystyle \large{jr + se - jb = f}[/tex]
Then subtract both sides by se to leave only jr and jb.
[tex] \displaystyle \large{jr + se - jb - se= f - se} \\ \displaystyle \large{jr - jb = f - se}[/tex]
For jr-jb, we can common factor out the j-term.
[tex] \displaystyle \large{j(r - b)= f - se}[/tex]
For r-b, treat it as one term. Then we divide both sides by r-b.
[tex] \displaystyle \large{ \frac{j(r - b)}{r - b} = \frac{f - se}{r - b} } \\ \displaystyle \large{ j= \frac{f - se}{r - b} }[/tex]
Hence, j = f - se / r - b
Alternate Solution
This is an alternate solution. We can simplify the fractional expression by separating each terms.
[tex] \displaystyle \large{ j= \frac{f - se}{r - b} } \\ \displaystyle \large{ j= \frac{f}{r - b} + \frac{ - se}{r - b} }[/tex]
Since se is in negative, we replace + as - and cancel -se to se.
[tex] \displaystyle \large{ j= \frac{f - se}{r - b} } \\ \displaystyle \large{ j= \frac{f}{r - b} - \frac{ se}{r - b} }[/tex]
The simplifed answer is j = ( f / r - b ) - ( se / r - b l
These two answers work and are correct.

Topic: Literal Equation (Factorization Involved)
g A manufacturer is making cylindrical cans that hold 300 cm3. The dimensions of the can are not mandated, so to save manufacturing costs, the manufacturer wants to make the can that uses the least material. What are the dimensions, to the nearest three decimal places, of the can that has the smallest surface area
Answer:
The dimensions that minimize the cost of materials for the cylinders have radii of about 3.628 cm and heights of about 7.256 cm.
Step-by-step explanation:
A cylindrical can holds 300 cubic centimeters, and we want to find the dimensions that minimize the cost for materials: that is, the dimensions that minimize the surface area.
Recall that the volume for a cylinder is given by:
[tex]\displaystyle V = \pi r^2h[/tex]
Substitute:
[tex]\displaystyle (300) = \pi r^2 h[/tex]
Solve for h:
[tex]\displaystyle \frac{300}{\pi r^2} = h[/tex]
Recall that the surface area of a cylinder is given by:
[tex]\displaystyle A = 2\pi r^2 + 2\pi rh[/tex]
We want to minimize this equation. To do so, we can find its critical points, since extrema (minima and maxima) occur at critical points.
First, substitute for h.
[tex]\displaystyle \begin{aligned} A &= 2\pi r^2 + 2\pi r\left(\frac{300}{\pi r^2}\right) \\ \\ &=2\pi r^2 + \frac{600}{ r} \end{aligned}[/tex]
Find its derivative:
[tex]\displaystyle A' = 4\pi r - \frac{600}{r^2}[/tex]
Solve for its zero(s):
[tex]\displaystyle \begin{aligned} (0) &= 4\pi r - \frac{600}{r^2} \\ \\ 4\pi r - \frac{600}{r^2} &= 0 \\ \\ 4\pi r^3 - 600 &= 0 \\ \\ \pi r^3 &= 150 \\ \\ r &= \sqrt[3]{\frac{150}{\pi}} \approx 3.628\text{ cm}\end{aligned}[/tex]
Hence, the radius that minimizes the surface area will be about 3.628 centimeters.
Then the height will be:
[tex]\displaystyle \begin{aligned} h&= \frac{300}{\pi\left( \sqrt[3]{\dfrac{150}{\pi}}\right)^2} \\ \\ &= \frac{60}{\pi \sqrt[3]{\dfrac{180}{\pi^2}}}\approx 7.25 6\text{ cm} \end{aligned}[/tex]
In conclusion, the dimensions that minimize the cost of materials for the cylinders have radii of about 3.628 cm and heights of about 7.256 cm.

A survey of 300 people found that 60 owned an iPhone, 75 owned a Blackberry, and 30 owned an Android phone. Furthermore, 40 owned both an iPhone and a Blackberry, 12 owned both an iPhone and an Android phone, and 8 owned a Blackberry and an Android phone. Finally, 3 owned all three phones. (a) How many people surveyed owned none of the three phones? (b) How many people owned a Blackberry but not an iPhone? (c) How many owned a Blackberry but not an Android?
Step-by-step explanation:
We let A be the set of those who owned an iPhone, B be the set of those who owned a Blackberry,
and C those that owned an Android. Therefore we have |A| = 60, |B| = 75, and |C| = 30. Also,
we know that |A ∩ B| = 40, |A ∩ C| = 12 and |B ∩ C| = 8. Finally, |A ∩ B ∩ C| = 3. Therefore,
by the principle of inclusion/exclusion, we have
|A ∪ B ∪ C| = |A| + |B| + |C| − |A ∩ B| − |A ∩ C| − |B ∩ C| + |A ∩ B ∩ C|
= 60 + 75 + 30 − 40 − 12 − 8 + 4
= 109
(a) Since there are 300 total people, there are 191 without one of the types of phone.
(b) Since |A ∩ B| = 40 and |B| = 75, there are 35 people with a Blackberry that don’t own
an iPhone.
(c) Since |B ∩ C| = 8 and |B| = 75, there are 67 people with a Blackberry that don’t own
an Android.

Julio is paid 1.2 times his normal hourly rate for each hour he works over 31 hours in a
week. Last week he worked 35 hours and earned $486.88.
Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation
how you know that your answer is reasonable.
9514 1404 393
Answer:
$13.60
Step-by-step explanation:
Julio worked 35 -31 = 4 overtime hours. For those 4 hours, he was paid at the rate 1.2r. Then his earnings were ...
31r +4(1.2r) = 486.88
35.8r = 486.88
r = 486.88/35.8 = 13.60
Julio's normal hourly rate is $13.60.
_____
Why do we believe this is reasonable?
35.8 is a reasonable number of hours to be paid for, considering that each of the 4 hours of overtime effectively adds 0.2 hours of straight-time pay, for a total of 35 +4(0.2) = 35.8 hoursthe pay rate is an integer number of cents per hour, and is in the right ballpark between 480/30 = $16 per hour and 480/40 = $12 per hour.we can check the numbers to verify: 31×$13.60 +4×1.2×$13.60 = $421.60 +4×16.32 = $486.88.Complete the ordered pair for the equation y = 3x + 5.

The cheerleaders are planning a bake sale to raise money for their competition. They made $150 at
the bake sale and spent $175 on supplies. What was their overall profit?
9514 1404 393
Answer:
-$25 (a loss of $25)
Step-by-step explanation:
Profit is the difference between revenue and cost.
profit = $150 -175 = -$25
The cheerleaders took a $25 loss on their bake sale.

Additional comment
The wording "made $150" can be interpreted two ways. We have taken it to mean the revenue from sales was $150. The same wording could also be used to indicate the profit was $150.

(4n^4+4n^3+16n^2)+4^2
9514 1404 393
Answer:
n^2 +n +4
Step-by-step explanation:
Since the divisor has only one term, the quotient is formed by dividing the terms one at a time.
[tex]\dfrac{4n^4+4n^3+16n^2}{4n^2}=\dfrac{4n^4}{4n^2}+\dfrac{4n^3}{4n^2}+\dfrac{16n^2}{4n^2}=\boxed{n^2 +n +4}[/tex]
__
Your long division tableau will subtract n^2×4n^2 = 4n^4 to form the new dividend 4n^3+16n^2. Then you will subtract n×4n^2 = 4n^3 to get the new dividend of 16n^2. The final quotient term is 4, and you will subtract 4×4n^2 to get a remainder of 0. You will have written the quotient as n^2+n+4.
