Given:
A profit of 60$.
To find:
An integer for the given situation.
Solution:
The given situation is "A profit of 60$".
We know that,
1. Negative integers are used to represent loss.
2. Positive integers are used to represent profit.
Here, the profit is 60$. So, the sign of required integer must be positive and the value of the integer is 60.
Therefore, the required integer is 60.

inverse laplace of L^-1 {5s/s^2 + 3s - 4}
Answer:
[tex]e^t+e^{-4t}[/tex]
Step-by-step explanation:
We have to simplify the original function using partial fraction, hence:
[tex]\frac{5s}{s^2+3s-4} =\frac{5s}{(s-1)(s+4)}\\\\=\frac{A}{s-1}+\frac{B}{s+4}\\\\Therefore:\\\\\frac{A(s+4)+B(s-1)}{(s-1)(s+4)}=\frac{5s}{(s-1)(s+4)}\\\\Eliminating\ the \ denominator:\\\\A(s+4)+B(s-1)=5s\\\\substitute\ s=1:\\\\A(1+4)+B(1-1)=5(1)\\\\5A=5\\\\A=1\\\\tsubstitute\ s=-4:\\\\A(-4+4)+B(-4-1)=5(-4)\\\\-5B=-20\\\\B=4\\\\Therefore\ substituting\ A\ and\ B\ gives:\\\\\frac{5s}{s^2+3s-4}=\frac{1}{s-1}+ \frac{4}{s+4}\\\\[/tex]
[tex]From\ Laplace\ inverse:\\\\But\ L^{-1}[\frac{1}{s-a} ]=e^{at}\\\\Hence:\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]=e^{t}+4e^{-4t}\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=e^{t}+4e^{-4t}[/tex]

Congruent Triangles
When two triangles are determined to be congruent, their side lengths and angles have the same measure.
We are given the condition that triangles FGH and ABC are congruent. This implies that sides FH and AC have the same measure, or, equivalently:
x + 12 = 18
Solving:
x = 18 - 12 = 6
x = 6
Similarly, sides HG and CB have the same length, thus:
w + 45 = 46
Solving:
w = 46 - 45 = 1
w= 1

Compute the surface area of the portion of the sphere with center the origin and radius 4 that lies inside the cylinder x^2+y^2=12
Answer:
16π
Step-by-step explanation:
Given that:
The sphere of the radius = [tex]x^2 + y^2 +z^2 = 4^2[/tex]
[tex]z^2 = 16 -x^2 -y^2[/tex]
[tex]z = \sqrt{16-x^2-y^2}[/tex]
The partial derivatives of [tex]Z_x = \dfrac{-2x}{2 \sqrt{16-x^2 -y^2}}[/tex]
[tex]Z_x = \dfrac{-x}{\sqrt{16-x^2 -y^2}}[/tex]
Similarly;
[tex]Z_y = \dfrac{-y}{\sqrt{16-x^2 -y^2}}[/tex]
∴
[tex]dS = \sqrt{1 + Z_x^2 +Z_y^2} \ \ . dA[/tex]
[tex]=\sqrt{1 + \dfrac{x^2}{16-x^2-y^2} + \dfrac{y^2}{16-x^2-y^2} }\ \ .dA[/tex]
[tex]=\sqrt{ \dfrac{16}{16-x^2-y^2} }\ \ .dA[/tex]
[tex]=\dfrac{4}{\sqrt{ 16-x^2-y^2} }\ \ .dA[/tex]
Now; the region R = x² + y² = 12
Let;
x = rcosθ = x; x varies from 0 to 2π
y = rsinθ = y; y varies from 0 to [tex]\sqrt{12}[/tex]
dA = rdrdθ
∴
The surface area [tex]S = \int \limits _R \int \ dS[/tex]
[tex]= \int \limits _R\int \ \dfrac{4}{\sqrt{ 16-x^2 -y^2} } \ dA[/tex]
[tex]= \int \limits^{2 \pi}_{0} } \int^{\sqrt{12}}_{0} \dfrac{4}{\sqrt{16-r^2}} \ \ rdrd \theta[/tex]
[tex]= 2 \pi \int^{\sqrt{12}}_{0} \ \dfrac{4r}{\sqrt{16-r^2}}\ dr[/tex]
[tex]= 2 \pi \times 4 \Bigg [ \dfrac{\sqrt{16-r^2}}{\dfrac{1}{2}(-2)} \Bigg]^{\sqrt{12}}_{0}[/tex]
[tex]= 8\pi ( - \sqrt{4} + \sqrt{16})[/tex]
= 8π ( -2 + 4)
= 8π(2)
= 16π

Ricardo has r minutes left on his cell-phone card. He wants to call his friend and still have 8 minutes left over to make calls later. Which expression describes the length of time he can talk to his friend?
A. 8 – r
B. 8r
C. r + 8
D. r – 8
Answer:
I would go with r - 8
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
if you subtract r by 8 then you will get the remaining minutes left on ricardo's cellphone card. Lets say r=20 so, 20-8=12. therefore, Ricardo would be able to call his friend for 12 minutes. hope this helped
Ming took a cab across town. His fare was $22, and he leaves an 18% tip. What is the total amount Ming pays the cab driver?
Answer:
$25.96
Step-by-step explanation:
Multiply the original price by the decimal value of the percentage then add that number to the original price
22*.18=3.96
3.96+22=25.96

Evaluate the following function for (3, -1):
f(x, y) = 2x – 3y + xy^2
Answer:
f(3, -1) = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
Step 2: Evaluate
Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)Multiply: f(3, -1) = 6 + 3 + 3Add: f(3, -1) = 9 + 3Add: f(3, -1) = 12In (3,-1) the first number is x and the second number is y.
Replace x and y in the equation and solve:
2x - 3y + xy^2 = 2(3) -3(-1) + (3)(-1)^2
Simplify:
6 + 3 +3 = 12
The answer is 12

SOMEONE PLZ GELP WITH NUMBER ONE.
Answer:
900
Step-by-step explanation:
Each group of 3 starred angles plus the 4th angle which is an interior angle of the triangle has a total measure of 360 degrees. The sum of the measures of the three angles of the triangle is 180 degrees.
total measure of the starred angles = 4 * 360 - 180
total measure = 900 degrees
Which graph best represents the solution for this inequality?
Step-by-step explanation:
6|4w + 2| - 2 > 10
6|4w + 2| > 12
|4w + 2| > 2
4w + 2 > 2 or 4w + 2 < -2
4w > 0 or 4w < -4
w > 0 or w < -1.
The correct graph is the 2nd option.

x reduced by 13 is atleast 15
Answer:
If you need an inequality here it is, can't really tell what you're trying to ask.
x-13≤15
Step-by-step explanation:
When we are talking about AT LEAST we are talking about the minimum.
For example, if I start a party and the age requirements for the party is at least 15, that means anyone who is 15 or older can enter the party.
So in your question, it says x reduced by 13 is at least 15, so reduced basically means to minus. So we are going to have x-13.
Then you have the "is at least 15". The at least is your sign for your inequality.
For example,
At least=≤
At most=≥
So the "is at least 15" is ≤15
Plug the numbers in: x-13≤15
find the area of the unshaded reason for these two problems
9514 1404 393
Answer:
a) 96 m²
b) 26,000 ft²
Step-by-step explanation:
The area of the unshaded region is the difference between the overall area of the rectangle and the area of the shaded region. It can also be found directly using the dimensions of the unshaded region.
a) We have the height of the right triangle, but need to know its base. The Pythagorean theorem can help with that. Let the base of the triangle be represented by x. Then ...
x² +16² = 20²
x² = 400 -256 = 144
x = √144 = 12
The area of the unshaded triangle is given by the formula ...
A = (1/2)bh
A = (1/2)(12)(16) = 96 . . . . square meters
__
b) The shaded area at upper left is a square 100 ft on a side. Its area is ...
A = s² = (100 ft)² = 10,000 ft²
The shaded area at upper right is a triangle with base and height 120 ft and 150 ft. Its area is ...
A = (1/2)bh = (1/2)(120 ft)(150 ft) = 9,000 ft²
The area of the overall rectangle is ...
A = LW = (300 ft)(150 ft) = 45,000 ft²
So, the unshaded area is ...
unshaded area = overall area - left shaded area - right shaded area
unshaded area = 45,000 ft² -10,000 ft² -9,000 ft² = 26,000 ft²
