Answer:
Below in bold.
Step-by-step explanation:
(a) Volume = volume of the cylinder + volume of hemisphere
= pi r^2 h + 1/2 * 4/3 pi r^3
= pi 2^2 3 + 2/3 pi 2^3
= 12pi + 16pi/3
= 52pi/3
= 52pi/3 in^3
= 54.45 in^3 to nearest hundredth.
(b) Surface area = area of base + area of curved part + area of the hemisphere
= pi 2^2 + 3 * 2pi 2 + 2 pi 2^2
= 4pi + 8 pi + 12pi
= 24pi in^2
= 75.40 to nearest hundredth.

jill bought 14 feet of fabric. the fabric cost $3.25 a foot, including tax. what is the total cost of the fabric?
Answer:
$45.5
Step-by-step explanation:
3.25 times 14 is 45.5
Answer:
$47.74
Step-by-step explanation:
Sales tax rate: 5%;
Price without tax: $3.25 dollars;
Amount of sales tax ≈ $0.16 dollars;
Price with sales tax ≈ $3.41 dollars;
Detailed calculations below:Amount of sales tax =
Sales tax rate × Price without sales tax =
5% × 3.25 =
5/100 × 3.25 =
0.05 × 3.25 =
0.1625 ≈
0.16;
Price with sales tax =
Price without sales tax + Amount of sales tax =
3.25 + 0.1625 =
3.4125 ≈
3.41;
means that we need to do 3.41 times 14 there your answer

A polynomial function has a root of -6 with multiplicity 1, a root of -2 with multiplicity 3, a root of 0 with multiplicity 2 and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?
The graph of the function is positive on (-6, -2). The graph of the function is negative on (-∞, 0). The graph of the function is positive on (-2, 4). The graph of the function is negative on (4,∞)
9514 1404 393
Answer:
(a) The graph of the function is positive on (-6, -2)
Step-by-step explanation:
A function of odd degree and positive leading coefficient will be negative from -∞ to the left-most zero. Here, that zero is -6. The multiplicity of that zeros is odd (1), so the sign changes to positive at that point, and remains positive until the next odd-multiplicity zero, which is -2, with multiplicity 3.
Hence the function is positive on the interval (-6, -2), matching choice A.

a

Four more than twenty-six time a number is equivalent to 12 times the same number less 15.
What is the number?
Answer:
n = -19/14
Step-by-step explanation:
Please transcribe this into a symbolic equation:
26n + 4 = 12n - 15
Then 14n = -19, or n = -19/14.

A stock has a beta of 1.5 and an expected return of 16.35%. What is the risk-free rate if the market rate of return is 12.5%?
96
Answer:
4.8%
Step-by-step explanation:
Given that :
Stock beta (B) = 1.5
Expected return = 16.35% = 0.1635
Maeket rate of return (Rm) = 12.5% = 0.125
Risk-free rate of return (Rf) =?
Using the relation :
Expected rate of return = risk free rate + Beta(market rate - Risk-free rate)
Expected rate of return = Rf + B(Rm - Rf)
Plugging our values :
0.1635 = Rf + 1.5(0.125 - Rf)
Open the bracket
0.1635 = Rf + 0.1875 - 1.5Rf
Collect like terms
0.1635 - 0.1875 = Rf - 1.5Rf
−0.024 = - 0.5Rf
Divide both sides by - 0.5
0.024 / 0.5 = Rf
Rf = 0.048
Rf = 0.048 * 100% = 4.8%
Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar.
If the triangles are similar, write a valid similarity statement.
Answer:
the AA~ congruency could be used, because
angle w=y,
angle t=z
and angle x is common
Step-by-step explanation:
That was my answer and I got it right :)
The given triangles are not similar.
What is similarity of triangles?Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given a figure of two triangles, ΔWXT and ΔYXZ
Here,
28/35 ≠ 30/38
WX/YX ≠ XT/XZ
We can conclude that, the corresponding sides are not in common ratio, so triangles are not similar.
Hence, The given triangles are not similar.

Solve the system, enter ur answer as an ordered triple.
Answer:
x = 1, y = -1, z = 3
Step-by-step explanation:
x - 2y + 2z = 9
y + 2z = 5
z = 3
According to the last equation, z is equal to 3 so we can plug that in and our new 2 equations will be:
x - 2y + 6 = 9
y + 6 = 5
We can subtract 6 from both sides of the second equation to end up with:
y = -1
Now plugging this into the first equation, we have:
x + 2 + 6 = 9
x + 8 = 9
Subtract 8 from both sides
x = 1

Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
You need to separate the 8 from each side of the equation. Picture it like this:
-104= 8 (multiplied by) x
To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.
-104/8=8x/8
-13=x
