Jeremy makes $4.70 every time he mows a lawn but it costs him $6.80 to refill the tank. If Jeremy mows 5 lawns using 3 tanks of gas, how much did he profit?
Show expression used and step by step explanation
Answer:
$3.10
Step-by-step explanation:
Money earned by mowing 5 lawns (income) = $4.70 x 5 = $23.50
Cost of filling 3 tanks (expenditure) = $6.80 x 3 = $20.40
Profit = income - expenditure
= $23.50 - $20.40
= $3.10
Evaluate the surface integral. S xz dS S is the boundary of the region enclosed by the cylinder y2 + z2 = 16 and the planes x = 0 and x + y = 10
If you project S onto the (x,y)-plane, it casts a "shadow" corresponding to the trapezoidal region
T = {(x,y) : 0 ≤ x ≤ 10 - y and -4 ≤ y ≤ 4}
Let z = f(x, y) = √(16 - y²) and z = g(x, y) = -√(16 - y²), each referring to one half of the cylinder to either side of the plane z = 0.
The surface element for the "positive" half is
dS = √(1 + (∂f/∂x)² + (∂f/dy)²) dx dy
dS = √(1 + 0 + 4y²/(16 - y²)) dx dy
dS = √((16 + 3y²)/(16 - y²)) dx dy
The the surface integral along this half is
[tex]\displaystyle \iint_T xz \,dS = \int_{-4}^4 \int_0^{10-y} x \sqrt{16-y^2} \sqrt{\frac{16+3y^2}{16-y^2}} \, dx \, dy[/tex]
[tex]\displaystyle \iint_T xz \,dS = \int_{-4}^4 \int_0^{10-y} x \sqrt{16+3y^2}\, dx \, dy[/tex]
[tex]\displaystyle \iint_T xz \,dS = \frac12 \int_{-4}^4 (10-y)^2 \sqrt{16+3y^2} \, dy[/tex]
[tex]\displaystyle \iint_T xz \,dS = 416\pi[/tex]
You'll find that the integral over the "negative" half has the same value, but multiplied by -1. Then the overall surface integral is 0.

If 6 hands is 2 feet and 3 feet is 7 arms and 3 arms is 2.5 heads, how many heads is 10 hands? Round to the nearest tenth
The question is an illustration of unit conversion
10 hands is equivalent to 6.5 heads
The given parameters are:
[tex]\mathbf{6\ hands = 2\ feet}[/tex]
[tex]\mathbf{3\ feet= 7\ arms}[/tex]
[tex]\mathbf{3\ arms= 2.5\ heads}[/tex]
Divide both sides of [tex]\mathbf{6\ hands = 2\ feet}[/tex] by 2
[tex]\mathbf{3\ hands = 1\ feet}[/tex]
Multiply both sides by 3
[tex]\mathbf{3 \times 3\ hands = 3 \times 1\ feet}[/tex]
[tex]\mathbf{9\ hands = 3\ feet}[/tex]
Recall that:
[tex]\mathbf{3\ feet= 7\ arms}[/tex]
Substitute 7 arms for 3 feet
[tex]\mathbf{9\ hands = 7\ arms}[/tex]
Divide both sides by 7
[tex]\mathbf{\frac{9\ hands}{7} = \frac{7\ arms}{7}}[/tex]
[tex]\mathbf{\frac{9\ hands}{7} = 1\ arm}[/tex]
Multiply both sides by 3
[tex]\mathbf{\frac{9\ hands}{7} \times 3= 1\ arm \times 3}[/tex]
[tex]\mathbf{\frac{27\ hands}{7}= 3\ arms}[/tex]
Recall that: [tex]\mathbf{3\ arms= 2.5\ heads}[/tex]
So, we have:
[tex]\mathbf{\frac{27\ hands}{7}= 2.5\ heads}[/tex]
Multiply both sides by 7
[tex]\mathbf{27\ hands= 17.5\ heads}[/tex]
Divide both sides by 27
[tex]\mathbf{1\ hands= \frac{17.5}{27}\ heads}[/tex]
Multiply both sides by 10
[tex]\mathbf{10 \times 1\ hands= 10 \times \frac{17.5}{27}\ heads}[/tex]
[tex]\mathbf{10 \times 1\ hands= \frac{175}{27}\ heads}[/tex]
[tex]\mathbf{10\ hands= \frac{175}{27}\ heads}[/tex]
[tex]\mathbf{10\ hands= 6.5\ heads}[/tex]
Hence, 10 hands is 6.5 heads

Answers:
Slope = undefined; y intercept = noneSlope = 2; y intercept = -2Slope = -1; y intercept = 1Slope = 0Slope = -4========================================================
Explanation:
1)
For any vertical line, the slope is always undefined. Recall that slope = rise/run. For a vertical line, the run is 0 because there is no left or right movement. This leads to a division by zero error. The vertical line is also parallel to the y axis, meaning that there isn't a y intercept whenever the line isn't directly on top of the y axis.
The equation of this vertical line is x = 3 as all points on this line have the same x coordinate of 3.
-----------------------
2)
We can use the slope formula for the points [tex](x_1,y_1) = (-1,-4) \ \text{ and } \ (x_2,y_2) = (3,4)[/tex]
So,
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-4)}{3-(-1)}\\\\m = \frac{4+4}{3+1}\\\\m = \frac{8}{4}\\\\m = 2\\\\[/tex]
The slope is 2.
The y intercept is -2 as this is the location where the diagonal line crosses the y axis.
The equation of this line is y = 2x-2.
-----------------------
3)
Same idea as problem 2.
[tex](x_1,y_1) = (-2,3)\\\\(x_2,y_2) = (3,-2)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-2-3}{3-(-2)}\\\\m = \frac{-2-3}{3+2}\\\\m = \frac{-5}{5}\\\\m = -1\\\\[/tex]
The slope is -1.
The y intercept is 1 because the line cuts through 1 on the y axis.
The equation is y = -1x+1 which is the same as y = -x+1.
-----------------------
4)
Pick any two points from the table. Each column represents a different (x,y) ordered pair point. Those two points selected are then plugged into the slope formula. I'll pick the first two columns.
[tex](x_1,y_1) = (1,-2)\\\\(x_2,y_2) = (2,-2)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-2-(-2)}{2-1}\\\\m = \frac{-2+2}{2-1}\\\\m = \frac{0}{1}\\\\m = 0\\\\[/tex]
Notice how the y coordinates are the same, which leads to a difference of 0 up top and ultimately the slope itself is also 0. We have a horizontal flat line here. All horizontal lines have a slope of 0.
The y intercept is -2 because all y values for this function are the same.
The equation is y = 0x-2 which is the same as y = -2.
-----------------------
5)
Again I'll pick the first two columns to plug into the slope formula, but you can pick any two columns you prefer.
[tex](x_1,y_1) = (-3,11)\\\\(x_2,y_2) = (-1,3)\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{3-11}{-1-(-3)}\\\\m = \frac{3-11}{-1+3}\\\\m = \frac{-8}{2}\\\\m = -4\\\\[/tex]
The slope is -4.
Use this slope value, along with any column from the table to form the (x,y) point, to plug into the slope intercept form below. I'll use the first column
y = mx+b
11 = -4*(-3)+b
11 = 12+b
11-12 = b
-1 = b
b = -1
The y intercept is -1.
The equation is y = -4x-1.

Answer:
a. reflection across line l
b. see attached
c. no
Step-by-step explanation:
a.The easiest transformation to put figure H' back where figure H is will be "reflection across line l". A reflection back across the same line of reflection puts the figure in its original location.
__
b.The attached figure shows the requested translation and labeling. The dim dotted figure is the original translation of H along vector EF. The reflection of that across line l is marked H''' as required.
__
c.No, figures H'' and H''' are not in the same location. One only needs to look at the diagram to see this.
In general the order of translation and reflection makes a difference. This means reflection of H to H', then translation to H'' will have a different result than translation of H to H(shadow), then reflection to H'''.

Find the values of m and b for this line.
Answer:
b=-5, m= - 3/-2
Step-by-step explanation:
Slope equation is y=mx+b. Slope is finding the rise(vertical change) over run(horizontal change). In this case, -3 is our negative rise and 2 is our run. Put that into fraction form, we get negative 3/2. In the slope equation, b represents the y-intercept(where the line touches the y-axis). In this case, it is -5. Hope this helps you!

How many pounds of chocolate that is 45% cocoa should be mixed with 6 pounds of pure cocoa mass to obtain a chocolate that is 78% cocoa? plz help im dying irl
Using a system of equation, the amount in pounds of chocolate required is 4
Let :
Number of pounds of chocolate = cHence, we can create an equation thus :
0.45c + 6(1) = 0.78(6 + c)
0.45c + 6 = 4.68 + 0.78c
Collect like terms
6 - 4.68 = 0.78c - 0.45c
1.32 = 0.33c
Divide both sides by 0.33
c = 1.32 / 0.33
c = 4
Hence, 4 pounds of chocolate is required.

How do the expressions 7+h2−5 and 10(h+2)−2h compare when h = 9? Drag a symbol into the box to correctly complete the statement. 7+h2−5 Response area 10(h+2)−2h when h = 9.
Answer:
8+h3-4
Step-by-step explanation:
10(h+2)−2h when h = 9.
The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expressions are,
⇒ 7 + h² - 5
⇒ 10 (h + 2) - 2h
Now,
Solve the expression for h = 9 and find the relation between them as;
Since, The expressions are,
⇒ 7 + h² - 5 ...(i)
⇒ 10 (h + 2) - 2h ...(ii)
Substitute h = 9 in (i), we get;
⇒ 7 + h² - 5 = 7 + 9² - 5
= 7 + 81 - 5
= 83
And, Substitute h = 9 in (ii), we get;
⇒ 10 (h + 2) - 2h = 10 (9 + 2) - 2 x 9
= 10 x 11 - 18
= 110 - 18
= 92
Thus, We get;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
Therefore, The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
