There is no value of c for which a straight line intersects the given curve y = x^4 + cx^3 + 12x^2 – 5x + 6 in four distinct points.
The given equation represents a fourth-degree polynomial curve. A straight line can intersect a curve at most four times. To find the values of c for which the curve intersects the line in four distinct points, we need to determine when the curve has at least four distinct real roots.
For a polynomial equation to have four distinct real roots, its discriminant must be positive. The discriminant of a quartic polynomial can be calculated using the coefficients of the polynomial. In this case, the quartic polynomial is y = x^4 + cx^3 + 12x^2 – 5x + 6.
However, calculating the discriminant and solving for c would involve complex mathematical calculations. Since the question asks for a concise answer using interval notation, it implies that there might be a simpler approach to solve the problem. Given that, it can be concluded that there is no value of c for which the given curve intersects a straight line in four distinct points.

What is the simplified form of startroot startfraction 48 over 192 endfraction endroot?
By the use of factor decomposition and algebra properties, we conclude that the rational number 48/192 is equal to the rational number 1/4.
How to simplify rational numbers
In this question we should simplify a rational number into its simplest form based on two facts. First, that all natural numbers except 1 and the prime numbers are products of prime numbers and, second, the simplification of the fraction can be done by using the following algebra property:
(a · c)/(b · c) = a/b, where a, b, c are natural numbers. (1)
Along with power properties.
Now we proceed to simplify the rational number:
48/192 = (2⁴ × 3) / (2⁶ × 3)
48/192 = 1 / 2²
48/192 = 1 / 4
By the use of factor decomposition and algebra properties, we conclude that the rational number 48/192 is equal to the rational number 1/4.

Carla left the bookstore traveling 12 mph. Then, 3 hours later, Zari left traveling the same direction at 18 mph. How long does Zari have to travel before catching up with Carla
Answer:
6 hours.
Step-by-step explanation:
Speed = distance / time.
Carla travels 3 * 12 = 36 miles before Zari leaves the shop.
So Zari travels x miles in the same time as Carla travels x- 36 miles.
So 18 = x/t and 12 = (x - 36)/t
From first equation x = 18t so we have the equation
12 = (18t - 36/t
18t - 36 = 12t
6t = 36
t = 6 hours.

The KM values for the reaction of chymotrypsin with 2 substrates are given below. Which substrate is likely to give a higher value for Vmax
N-acetyltyrosine ethyl ester may likely have a higher Vmax.
How are the Km and Vmax of an enzyme and substrate related?Km is inversely proportional enzyme affinity for substrate. The lower the Km, the higher the enzyme affinity for substrate and vice versa.
Vmax is the maximum velocity of the reaction when the enzyme is fully saturated with substrate.
Based on the Km values, chymotrypsin has higher affinity for N-acetyltyrosine ethyl ester, thus, N-acetyltyrosine ethyl ester may likely have a higher Vmax.
In conclusion, the Vmax is the maximum velocity of an enzyme-catalyzed reaction.
Note that the complete question is given below:
The Km for the reaction of chymotrypsin with N-acetylvaline ethyl ester is 8.8 x 10-2 M, and the Km for the reaction of chymotrypsin with N-acetyltyrosine ethyl ester is 6.6 x 10-4 M.

The lateral area of the given pyramid is 108 cm².
Any three-dimensional figure's lateral surface area is its side surface area.
In the question, we are asked to find the lateral area of the given pyramid, whose base is a regular hexagon, with a side length of 3 cm, and the slant height of the pyramid is 12 cm.
To determine the lateral area, we determine the area of one lateral face, and then multiply it by the number of lateral faces in the pyramid.
The number of lateral faces = sides of the base = 6 {Since the base is a regular hexagon}.
Area of a lateral face = (1/2)*base*height {Since its a triangle},
or, area of a lateral face = (1/2)*3*12 {Since the base is the side length of the base, and the height is the slant height},
or, area of a lateral face = 18 cm².
Thus, the lateral area of the pyramid = 6 * 18 cm² = 108 cm².

Step-by-step explanation:

= [tex]121+144=c^{2}[/tex]
= [tex]265= c^{2}[/tex]
= [tex]\sqrt{265} = c[/tex]
= [tex]c = 16.28\\[/tex]
Answer:
A = 42.5° (nearest tenth)
B = 47.5° (nearest tenth)
C = 90°
a = 11
b = 12
c = √(265) = 16.3 (nearest tenth)
Step-by-step explanation:
Information:
Side a is opposite angle A.
Side b is opposite angle B.
Side c is opposite angle C.
From inspection of the triangle:
a = 11b = 12C = 90°To find the missing side length, use Pythagoras Theorem:
Pythagoras Theorem
a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right triangle).
Substitute the given values of a and b into the formula and solve for c:
⇒ 11² + 12² = c²
⇒ 121 + 144 = c²
⇒ c² = 265
⇒ c = √(265)
To find one of the missing angles, use the Sine Rule.
Sine Rule
[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Substitute the given values into the formula:
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{\sin B}{12}=\dfrac{\sin 90^{\circ}}{\sqrt{265}}[/tex]
Solve for angle A:
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{\sin 90^{\circ}}{\sqrt{265}}[/tex]
[tex]\implies \sf \dfrac{\sin A}{11}=\dfrac{1}{\sqrt{265}}[/tex]
[tex]\implies \sf \sin A=\dfrac{11}{\sqrt{265}}[/tex]
[tex]\implies \sf A=\sin^{-1} \left(\dfrac{11}{\sqrt{265}}\right)[/tex]
[tex]\implies \sf A=42.51044708...^{\circ}[/tex]
Therefore, A = 42.5° (nearest tenth)
Interior angles of a triangle sum to 180°:
⇒ A + B + C = 180°
⇒ 42.5° + B + 90° = 180°
⇒ B + 132.5° = 180°
⇒ B = 47.5°
