Factor xy−4y+4x−16 by grouping
Answer:
[tex](y+4)(x-4)[/tex]
Step-by-step explanation:
Given the expression:
[tex]xy-4y+4x-16[/tex]
[tex](xy-4y)+(4x-16)[/tex]
Take the common factor
[tex]y(x-4)+4(x-4)[/tex]
[tex](y+4)(x-4)[/tex]
The factored expression is (x - 4)(y + 4).
To factor the expression xy - 4y + 4x - 16 by grouping, we first group the terms in pairs and look for common factors:
xy - 4y + 4x - 16
Now, let's factor by grouping:
Step 1: Group the terms in pairs.
(xy - 4y) + (4x - 16)
Step 2: Factor out the common factor from each group.
In the first group, we can factor out "y" from the two terms:
y(x - 4)
In the second group, we can factor out "4" from the two terms:
4(x - 4)
Step 3: Notice that both groups have a common factor of (x - 4). Factor it out.
(x - 4)(y + 4)
So, the factored expression is (x - 4)(y + 4).

Answer:
w = 7, 8/5
Step-by-step explanation:
(7 - w) (5w - 8) = 0
(7 - w) × (5w - 8) = 0
7 × 5w - 7 × 8 - w × 5w + w × 8 = 0
35w - 56 - 5w² + 8w = 0
- 5w² + 43w - 56 = 0
5w² - 43w + 56 = 0
5w² - 35w - 8w + 56 = 0
5w(w - 7) - 8(w - 7) = 0
(w - 7) (5w - 8) = 0
w - 7 = 0 OR 5w - 8 = 0
w = 7 OR w = 8/5
Thus, the value of w is 7, 8/5
A regression equation is obtained for a collection of paired data. It is found that the total variation is 20.711 , the explained variation is 18.592 , and the unexplained variation is 2.119 . Find the coefficient of determination.
Answer:
0.898
Step-by-step explanation:
The formula for the Coefficient of determination = ratio of explained variation to Total variation
From the above question, we have the following values
Explained variation = 18.592
Total variation = 20.711
The coefficient of determination = 18.592 : 20.711
= 18.592/20.711
= 0.8976872194
Approximately ≈ 0.898
Therefore, the coefficient of determination is 0.898

What is the function g(x) created from f(x) = x2 by moving the graph left 7 units, adding vertical compression by a factor of 1 6 , and shifting the graph down 8 units?
Answer:
g(x) = (1/6)(x +7)^2 -8
Step-by-step explanation:
The transformation ...
g(x) = a·f(x -h) +k
represents vertical scaling by a factor of 'a', right shift by h units, and up shift by k units. You want the function g(x) for f(x) = x^2, a = 1/6, h = -7, and k = -8. Those transformations give you ...
g(x) = (1/6)(x +7)^2 -8
Use cylindrical coordinates.
Find the volume of the solid that is enclosed by the cone
z = \sqrt{x^2+y^2} and the sphere x2 + y2 + z2 = 32.
Answer: Find the answer in the attachment
Step-by-step explanation:
The volume constrained both by the cone and the sphere is [tex]21.905\pi[/tex] cubic units.
The volume of a solid in cylindrical coordinates ([tex]V[/tex]) can be determined by the following triple integral:
[tex]V = \iiint dz\,r\,dr\,d\theta[/tex] (1)
The solid is constrained by the following equations in cylindrical coordinates:
Sphere
[tex]r^{2}+z^{2} = 32[/tex] (2)
Cone
[tex]z = r[/tex] (3)
The integration limits can be identified by using the following intervals:
[tex]z \in [0, +\sqrt{32-4^{2}}][/tex], [tex]r \in [0,4][/tex], [tex]\theta \in [0,2\pi][/tex]
And the triple integral has the following form:
[tex]V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\int\limits_{0}^{+\sqrt{32-r^{2}}} dz\,r\,dr\,d\theta[/tex] (4)
Now we proceed to integrate the expression thrice:
[tex]V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\sqrt{32-r^{2}}\,r\,dr\,d\theta = 10.952\int\limits_{0}^{2\pi}\,d\theta = 21.905\pi[/tex]
The volume constrained both by the cone and the sphere is [tex]21.905\pi[/tex] cubic units.

Find the largest value of $n$ such that $5x^2+nx+48$ can be factored as the product of two linear factors with integer coefficients.
Answer:
[tex]n = 241[/tex]
Step-by-step explanation:
Given
[tex]5x^2 + nx + 48[/tex]
Required
Determine the highest value of n
From the given equation, 5 is a prime number;
So, the factors of x² is 5x and x or -5x and -x
Since [tex]5x^2 + nx + 48[/tex] has all shades of positive terms, we'll make use of 5x and x
The factorized expression can then be:
[tex](5x + a)(x + b)[/tex]
Open the brackets
[tex]5x^2 + ax + 5bx + ab[/tex]
Equate this to the given expression
[tex]5x^2 + ax + 5bx + ab = 5x^2 + nx + 48[/tex]
[tex]5x^2 + (a + 5b)x + ab = 5x^2 + nx + 48[/tex]
By direct comparison;
[tex]5x^2 = 5x^2[/tex]
[tex](a + 5b)x = nx[/tex]
[tex]a + 5b = n[/tex] ---- (1)
[tex]ab = 48[/tex] --- (2)
From (2) above, the possible values of a and b are:
[tex]a = 1, b = 48[/tex]
[tex]a = 2, b = 24[/tex]
[tex]a = 3, b = 16[/tex]
[tex]a = 4, c = 12[/tex]
[tex]a = 6, b = 8[/tex]
[tex]a = 8, b = 6[/tex]
[tex]a = 12, b = 4[/tex]
[tex]a = 16, b = 3[/tex]
[tex]a = 24, b = 2[/tex]
[tex]a = 48, b = 1[/tex]
Of all these values; the value of a and b that gives the highest value of n is;
[tex]a = 1, b = 48[/tex]
So;
Substitute 1 for a and 48 for b in (2) [tex]a + 5b = n[/tex]
[tex]1 + 5 * 48 = n[/tex]
[tex]1 + 240 = n[/tex]
[tex]241 = n[/tex]
[tex]n = 241[/tex]
Hence, the largest value of n is 241
Answer:
Step-by-step explanation:
The two factors of $5x^2+nx+48$ must be in the form $(5x+A)(x+B)$. $A$ and $B$ must be positive integers to form the largest value of $n$. Therefore, $AB=48$ and $5B+A=n$. To form the largest value of $n$, $B$ must equal $48$. Therefore, $A=1$. \[5B+A=5(48)+1=\boxed{241}\]

The reason behind this answer is because you first multiply 2.5 by 60 for the 60 minutes in an hour and ultimately get 150 then you multiply that answer by 8 to get 1200.
F = 2xi+3yj and σ is the cube with opposite corners at (0,0,0) and (3,3,3), oriented outwards. Find the flux of the flow field F across σ.
Answer:
the flux of the flow field F across σ = 135
Step-by-step explanation:
Given that :
F = 2xi + 3yj
and σ is the cube with opposite corners at (0,0,0) and (3,3,3) oriented outwards.
Using divergence theorem,
[tex]\iint \ F.ds = \iiint \ div. f \ dV[/tex]
[tex]div \ f = \dfrac{\partial }{\partial x}2x + \dfrac{\partial}{\partial y }(3y)[/tex]
f = 2 +3 = 5
where ;
F = 2xi + 3yj
Thus , the triple integral can now be ;

You want to have $2 million in real dollars in an account when you retire in 35 years. The nominal return on your investment is 9.94% and the inflation rate is 3.2%. What is the real amount you must deposit each year to achieve your goal?
a. $20,403.
b. $7,482.
c. $16,017.
d. $18,887.
e. $19,711.
Answer:
b. $7,482.
Step-by-step explanation:
20,403 nets $5,996,106 after 35 years.
7,482 nets $2,198,837 after 35 years.
$7,482 is over 2 million and the smallest amount, so you don't have to solve for the other ones.
The real amount that must deposit each year to achieve your goal is $16,017 option (c) is correct.
What is invested amount?An investment is a payment made to acquire the securities of other firms with the intention of making a profit.
First, we will calculate the real rate of interest:
r = [(1+nominal rate)/(1+inflation rate)] - 1
Nominal rate = 9.94% = 0.094
Inflation rate = 3.2% = 0.032
r = [(1+0.094)/(1+0.032)] - 1
After calculating,
r = 0.0653 or 6.53%
Deposit amount each year:
Future value = PV[(1+r)ⁿ - 1]/(r)
2000000 = PV[(1+0.0653)³⁵ - 1]/(0.0653)
After calculating,
PV = $16020.544
The value $16020.544 is near the $16,017.
Thus, the real amount that must deposit each year to achieve your goal is $16,017 option (c) is correct.

Calculate the producers' surplus for the supply equation at the indicated unit price p.(Round your answer to the nearest cent.) p = 120 + q; p = 165
Answer: ps = 1012.5
Therefore the producers' surplus for the supply equation at the indicated unit price p is 1012.5
Step-by-step explanation:
Given that;
p = 120 + q ; p = 165
Now to find the producer's surplus for supply equation p=f(q) at the indicated unit price; we find p
so from p = 120 + q ; p = 165, if we substitute for q
120 + q = 165
q = 165 - 120 = 45
so
ps = ⁴⁵∫₀ ( 165 - (120+q) dq
ps = ⁴⁵∫₀ ( 45 - q) dq
USING THE EXPRESSION [ xⁿdx = xⁿ⁺¹ / n+1]
ps = [45q - q²/2]₀⁴⁵
ps = [45(45) - 45²/2] [45(0) - (0)²/2]
ps = [2025 - 1012.5] - [0]
ps = 1012.5
Therefore the producers' surplus for the supply equation at the indicated unit price p is 1012.5

A. 8.3
B.18.7
C. 10.4
D. 1.04
Step-by-step explanation:
p(x) = 0.03x² + 0.56x + 6.35
A. Determination of p(3)
p(x) = 0.03x² + 0.56x + 6.35
x = 3
p(3) = 0.03(3)² + 0.56(3) + 6.35
p(3) = 0.03(9) + 1.68 + 6.35
p(3) = 0.27 + 1.68 + 6.35
p(3) = 8.3
B. Determination of p(13)
p(x) = 0.03x² + 0.56x + 6.35
x = 13
p(13) = 0.03(13)² + 0.56(13) + 6.35
p(13) = 0.03(169) + 7.28 + 6.35
p(13) = 5.07 + 7.28 + 6.35
p(13) = 18.7
C. Determination of p(13) – p(3)
From A and B above,
p(13) = 18.7
p(3) = 8.3
p(13) – p(3) = 18.7 – 8.3
p(13) – p(3) = 10.4
D. Determination of p(13) – p(3) / 13 – 3
From C above,
p(13) – p(3) = 10.4
p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3
= 10.4 / 10

Jenna bought a coat on sale for $120, which was 2/3 of the original price. What was the original price of the coat?
Answer:
$
180
Step-by-step explanation:
The original price is the quotient between $120 and 2/3, we get:
P = $180
What is the original price?
We know that 2/3 of the original price is $120, then to get the original price, we need to take the quotient between $120 and 2/3.
[tex]P = \frac{\$120}{2/3} = (3/2)*\$ 120[/tex]
By taking that quotient we will see that the original price of the coat is:

A cash box of $1 and $5 bills is worth $45. The number of $1 bills is 3 more than the number of $5 bills. How many of each bill does it contain?
Answer:
There are 10 $1 bills and 7 $5 bills
Step-by-step explanation:
7($5 bills) x 5
=35
7+3 (3 more $1 bills)
=10
10+35
=45
Answer:
$1: 10
$5: 7
Step-by-step explanation:
To find out how many of each bill is in the cash box, create an expression
x = the dollar bills
This makes the $5 bills 5x and the $1 bills x (this can also be 1x)
When it says "The number of $1 bills is 3 more than the number of $5 bills" This means that the number of $1 is x + 3 and the number of $5 is 5x
When you put it together the expression will be x + 3 + 5x = 45
First add x and 5x, making it 6x
Next subtract 3 from each side, which makes the equation 6x = 42
Lastly, divide 6 from each side, this means that x = 7
To find out how many bills there are substitute 7 wherever there is an x
This mean that the number of $1 is 7 + 3 (10), and the number of $5 bills are 5x7 (35), but its just 7 because they are $5 each
