Answer:

c: no solution

Step-by-step explanation:

Final answer:

The function f(x) = 3x^2 + 2x + 4 has no real zeros because the discriminant (b^2 - 4ac) is negative, indicating that the roots of the quadratic equation are complex.

Explanation:

The question asks us to identify the real zeros of the function f(x) = 3x2 + 2x + 4. To find the real zeros, we look for values of x that make f(x) equal to zero. We can approach this by attempting to solve the quadratic equation 3x2 + 2x + 4 = 0 using the quadratic formula, which is x = [-b ± √(b2 - 4ac)]/(2a), where a = 3, b = 2, and c = 4.

Inserting these values into the formula, we get:

x = [-2 ± √((2)2 - 4*3*4)]/(2*3)

x = [-2 ± √(4 - 48)]/(6)

x = [-2 ± √(-44)]/(6)

Since the part under the square root (√(-44)) is negative, this indicates that the solutions for x are complex, not real. Therefore, the equation 3x2 + 2x + 4 has no real solutions.

Answer:

Maximum number of relative extremes contained in the graph of this function = 3.

Step-by-step explanation:

We have been given function [tex]f\left(x\right)=3x^4-x^2+4x-2[/tex].

Now we need to find about what is the maximum number of relative extremes contained in the graph of the given function [tex]f\left(x\right)=3x^4-x^2+4x-2[/tex].

Degree of the given function = 4.

Because degree is the highest power of variable.

Then relative number of extrema = degree - 1 = 4 - 1 = 3

Hence final answer is 3.

Explanation is in above pictures.

The verbal statement 'three times a number increased by 8 is at most 40 more than the number' is expressed as the inequality 3x + 8 ≤ x + 40 in mathematical terms. This inequality simplifies to x ≤ 16, indicating that the original number must be 16 or less.

The question involves translating a verbal statement into a mathematical inequality. The phrase 'three times a number increased by 8 is at most 40 more than the number' can be represented algebraically. Begin by letting the variable 'x' represent the unknown number. The phrase 'three times a number' translates to '3x', 'increased by 8' means we add 8, and 'is at most' indicates that the expression is less than or equal to something. '40 more than the number' is translated to 'x + 40'. Combining these elements, we have the inequality 3x + 8 ≤ x + 40.

To solve this inequality, we would subtract 'x' from both sides to get 2x + 8 ≤ 40, and then subtract 8 from both sides to find 2x ≤ 32. Next, we would divide both sides by 2 to get x ≤ 16. This tells us that the original number must be 16 or any number less than 16 to satisfy the condition described in the question.

Understanding how to translate verbal statements into mathematical expressions and inequalities is a fundamental math skill. Knowing terms such as 'at most' is crucial for setting up the correct inequality. This situation is an application of basic algebra to interpret and solve problems.

Answer:

x=1 and y = 9

Step-by-step explanation:

Solving using elimination method:

In elimination method we solve equations such that one variable cancels out and we find the value of other variable.

x + 7y = 64

x + 3y = 28

Subtracting both equations:

x + 7y = 64

x + 3y = 28

-   -       -

___________

0 +4y = 36

y= 36/4

y=9

Putting value of y in one of the equation,

x+7y = 64

x + 7(9) = 64

x + 63 = 64

x = 64-63

x = 1

So, x=1 and y=9

Solving using substitution method:

In substitution method, we substitute value of one variable into other value

x + 7y = 64   (1)

x + 3y = 28   (2)

From 1

x = 64 -7y

Putting value of x in eq(2)

(64 -7y) + 3y = 28

64 -7y +3y =28

64 - 4y = 28

-4y = 28 -64

-4y = -36

y = -36/-4

y = 9

Putting value of y in eq (1)

x + 7y = 64

x + 7(9) = 64

x + 63 = 64

x = 64 - 63

x = 1

So, x=1 and y = 9.

Answer:

Radius of the cone is 6 unit.

Step-by-step explanation:

Given:

Lateral Surface Area of Cone, LSA = 100π unit²

Total Surface Area of cone, TSA = 136π unit²

Let, r be the radius of cone.

According to the question,

Total Surface area = lateral surface area + Area of circle

136π = 100π + πr²

πr² = 36π

r² = 36

r = 6

Therefore, Radius of the cone is 6 unit.

The radius of the cone is 6 units.

To solve for the radius of the cone, we need to use two formulas: the lateral area (LA) and the total surface area (TSA) of a cone. The given values are:

We use the following formulas:

From the given values:

From the first equation, we can express l in terms of r:

l = 100 / r

Substitute l in the second equation:

136 = r² + r(100 / r)
=> 136 = r² + 100

Rearrange the equation to solve for r:

r² = 136 - 100
=> r² = 36
=> r = √36
=> r = 6.

Step-by-step explanation:

If the triangle is equilateral :

2x +y/2 =  5x/3+y + ½  = 2/3x +2y +5/2

so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)

the simplest is :  P = 3(2x +y/2)

Answer:

939,520

Step-by-step explanation:

You round up because you have a 5 in the tens place and as the saying goes: "Five or more up the score, four or less let it rest"

The number  939,515 rounded to the nearest tens is 939520.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, A number 939515 and we have to round it to the nearest ten.

To round this number to the nearest ten we'll look at the digit at the unit's place.

The digit at the unit place is 5 so we'll add 1 to the tens digit and make the unit digit zero.

Therefore the number 939515 rounded to the nearest tens place is

939520.

Answer:

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A= [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 8 and h = 2, so

A= 0.5 × 8 × 2 = 8 units² → D

Step-by-step explanation:

The highest point of a parabola is at the vertex.

x = -b / (2a)

x = -1 / (2×-0.0023)

x ≈ 217.4

y = (217.4) − 0.0023 (217.4)²

y ≈ 108.7

The horizontal distance can be found when the potato lands (y=0):

0 = x − 0.0023x²

0 = x (1 − 0.0023x)

x = 0, x ≈ 434.8

So the potato reaches a maximum height of 108.7 m and travels a horizontal distance of 434.8 m.

The height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.

To find the height point of the trajectory and the horizontal distance the potato travels before hitting the ground, we can use the equation y=x-0.0023x^2 to represent the trajectory. Since the trajectory is a parabola, the height point corresponds to the vertex of the parabola. To find the vertex, we can use the formula x = -b / (2a), where a = -0.0023 and b = 1. To find the horizontal distance the potato travels before hitting the ground, we need to find the x-intercepts of the parabola, which correspond to the points where y = 0.

First, let's find the height point:

Using the formula x = -b / (2a) and substituting the values, we get:

x = -1 / (2 * (-0.0023)) = 217.39 meters

Now, let's find the horizontal distance:

Setting y = 0 and solving for x, we get:

0 = x - 0.0023x^2

0 = x(1 - 0.0023x)

x = 0 or x = 434.78 meters

Therefore, the height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.
