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'''.
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

. There are seven people in a club: A, B, C, D, E, F, and G. A committee of 3 people is formed. What is the probability that G is on the committee
Step-by-step explanation:
there are 7 over 4 total possibilities to create a group of 3 or if 7.
that is
7! / (4! × (7-4)!) = 7×6×5 / 3×2 = 7×5 = 35
for the probability we need also the number of the desired cases, a the probability is
number of desired cases / number of total cases
the desired cases are all combinations, where G is a part of.
for that we make G a constant, and now we have only 6 variable candidates for the other 2 positions on the committee.
that is 6 over 2 or
6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15
so, the probability that G is in the committee is

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

Lin runs 5 laps around a track in 8 minutes. If Lin runs 21 laps at
the same rate, how long does it take her?
a) 13.13 minutes
b) 441 minutes
c) 33,6 minutes
d) 1.6 minutes
Answer:
It will take 25.2 minutes to complete 21 laps.
Step-by-step explanation:
The rate of covering 5 laps is:
v = 6/5
Therefore, the time taken to cover 21 laps is:
t = 21/v
t = 21*6/5
t = 25.2
Hence, it will take 25.2 minutes or 25 minutes 12 seconds for Lin to complete 21 laps.
When interest is compounded

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

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.

If the point (-7,5) lies on the graph of y=f(x), which of the following points must lie on the graph of its
inverse?
Answer:
option 1
Step-by-step explanation:
Given (x, y ) lies on the graph of f(x) , then the corresponding point on the graph of its inverse is (y, x ) , so
If point (- 7, 5 ) lies on the graph of f(x) , then
(5, - 7 ) lies on the graph of its inverse
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.
