Write the equation of the line parallel to y = 3x -5 and that passes through(1, -7).
Answer:
Explanation:
The line is parallel to y = 3x -5, meaning it has the same slope; therefore, we already know that our equation takes the form
\(y=3x+b\)Now, the second requirement is that the line should pass through the point (1, -7), meaning it should satisfy the condition that when x = 1, y = -7. Putting in these values of x and y in the above equation gives
\(-7=3(1)+b\)\(-7=3+b\)subtracting 3 from both sides gives
\(-10=b\)With the value of b in hand, we now have the equation of the line
\(\boxed{y=3x-10}\)which is our answer!

As per the given data, the number of integers in R ∩ S is 2, and the correct answer is (B) Two.
In mathematics, the intersection of two sets is a set containing all elements that are members of both sets.
In symbols, the intersection of two sets A and B is denoted by A ∩ B, and it contains all elements that belong to both A and B.
The intersection of two sets contains only the elements that are present in both sets. In this case,
R ∩ S = {x | x > 0 and x < 3}
The integers that are present in this set are 1 and 2.

What is Trigonometric function?In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
What is Pythagorean theorem?In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
Given,
a = 10, b = 2
Draw the figure using the given data
Apply Pythagorean theorem to find the third side or hypotenuse
\(c^{2}=a^{2} +b^{2}\)
\(c^{2}=10^{2}+2^{2}\\c^{2}=100+4\\ c^{2}=104\\ c=\sqrt{104}\)
c = 10.19 units
We know sin θ = Opposite side / Hypotenuse
Sin A = \(\frac{10}{10.19}\)
sin A = 0.98
cos θ = Adjacent side / Hypotenuse
cos A = \(\frac{2}{10.19}\)
cos A =0.20
tan θ = Opposite side / Adjacent side
tan A = \(\frac{10}{2}\)
tan A = 5
Hence, the Exact values are follows:
sin A = 0.98
cos A = 0.20
tan A = 5

In ADEF, f= 33 inches, ZF=140° and ZD=5°. Find the length of e, to the nearest 10th
of an inch.
The length of e is 29.53 inches.
what is Sine Law?In the following, the law of sine is presented in detail: In a triangle, the sine of angle A divided by side "a" equals the sine of angle B divided by side "b" equals the sine of angle C divided by side "c".
Given:
f= 33 inches
<F= 140, <D = 5
Now,
<E= 180 - (<F+ <D) = 180 - (140 + 5) = 35
Using Sine law
sin F / f = sin E/ e
sin 140 / 33 = sin 35 / e
0.642/ 33 = 0.573 / e
0.0194 e= 0.573
e= 29.53 inches

A rectangular building is to have a volume of 8000 fr^3. Annual heating and cooling costs will amount to $2/ft^2 for its top, front, and back, and $4/ft^2 for the two end walls. What dimensions of the building would minimize these annual heating and cooling costs?
Answer:
the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft
Step-by-step explanation:
If the length, width and height of the building are represented by a, b and c, then we have:
Volume = abc
We are given volume as 8000 ft³. Thus;
abc = 8000
Top area = ab
Front area = ac
Back area = ac
End walls area = bc
We are told that cooling costs will amount to $2/ft² for its top, front, and back, and $4/ft² for the two end walls.
Thus, cooling cost equation is;
X = 2(ab) + 2(ac) + 2(ac) + 4bc + 4bc
X = 2ab + 4ac + 4bc
Now, from the volume equation where abc = 8000.
c = 8000/ab
Thus;
X = 2ab + 4a(8000/ab) + 4b(8000/ab)
X = 2ab + 32000/b + 32000/a
To minimize, we will find the a and b derivative and set the equation to zero in both cases.
Thus;
dX/da = 2b - 32000/a² = 0
2b = 32000/a² - - - eq(1)
Also;
dX/db = 2a - 32000/b² = 0
2a = 32000/b² - - - (eq 2)
Making a the subject in eq 2 gives;
a = 32000/2b²
a = 16000/b²
Putting 16000/b² for a in eq (1) gives;
2b = 32000/(16000/b²)²
2b = 32000b⁴/256000000
2b = b⁴/8000
Multiply both sides by 8000 to get;
2b × 8000 = b⁴
16000b = b⁴
Divide both sides by b to get;
16000 = b³
b ≈ 25.2 ft
Putting 25.2 for b in a = 16000/b², we have;
a = 16000/25.2²
a ≈ 25.2
Putting a and b = 25.2 in the volume equation, we have;
25.2 × 25.2 × c = 8000
c = 8000/(25.2 × 25.2)
c = 12.6 ft
Thus, the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft

The graph of g(x) is obtained from the graph of f(x) by the following transformations:
- A horizontal stretch by a factor of 9. This is because the graph of g(x) is 9 times wider than the graph of f(x).
- A vertical translation down by 2 units. This is because the graph of g(x) is 2 units lower than the graph of f(x).
In other words, to obtain the graph of g(x) from the graph of f(x), we stretch the graph horizontally by a factor of 9 and then translate it down by 2 units.
Here is a more detailed explanation of the transformations:
- Horizontal stretch by a factor of 9: To stretch the graph horizontally by a factor of 9, we multiply all of the x-coordinates by 9. This means that every point on the graph of f(x) will be moved 9 units to the right on the graph of g(x).
- Vertical translation down by 2 units: To translate the graph down by 2 units, we subtract 2 from all of the y-coordinates. This means that every point on the graph of f(x) will be moved 2 units down on the graph of g(x).
