Answers

Answer 1

Answer:

The graph y = 18x2 + mx + 2= 12

So the answer is 12

Answer 2

The value of m does the graph of y = 18 x² + m x + 2 have exactly one x-intercept is 12.

What is Intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

We have Equation.

y = 18 x² + m x + 2

Now, to find exactly one intercept we will use Discriminant Method as

D = m² - 4 x 18 x 2 = 0

m² - 144 = 0

m² = 144

m = -12 or m = 12

Thus, the required value of m is 12.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Alexander sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.

8 visitors purchased no costume.

340 visitors purchased exactly one costume.

28 visitors purchased more than one costume.


If next week, he is expecting 600 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.

Answers

Answer:

Step-by-step explanation:

1) Add all of the origanal visitors (376)

2) Find the ratio (28/376) = 0.0744

3) Either 28/376 * 600 OR 0.0744 * 600 (I would recomend the fraction for more accurate answers, but because it says to round to the nearest whole number either will work, but you should still use fraction)

A student uses the equation tangent theta = startfraction s squared over 49 endfraction to represent the speed, s, in feet per second, of a toy car driving around a circular track having an angle of incline theta, where sine theta = one-half. to solve the problem, the student used the given value of sine theta to find the value of tangent theta and then substituted the value of tangent theta in the equation above to solve for s. what is the approximate value of s, the speed of the car in feet per second? 5.3 7.5 9.2 28.3

Answers

The approximate value of the speed of the car in feet per second is A. 5.32 ft/s.

How to find the spped?

An equation is an expression that shows the relationship between two or more numbers and variables. In this case, tan(θ) = s² / 49

sinθ = 1/2

θ = sin⁻¹ (0.5) = 30⁰

tan(30) = s² / 49

s = 5.32 ft/s

Therefore, the approximate value of the speed of the car in feet per second is 5.32 ft/s.

because you take +3 and subtract it from both sides so now you are left with 2x> -12 then you divide both sides by 2 and now you are left with x>-6 and since the arrow is facing to the right you graph the line to the right

The graph that represents the solution set for x > -6 is Graph D.

What is Number line?

In mathematics, a number line is a straight line that represents numbers and their relative positions. It is a visual representation of the real number system.

To find the solution set for the inequality 2x + 3 > -9,

2x + 3 > -9

Subtract 3 from both sides:

2x > -12

Divide both sides by 2:

x > -6

The solution set for the inequality is x > -6, which means that x is greater than -6.

So, Among the given graphs, the graph that represents the solution set for x > -6 is Graph D.

π.

Answers

[tex]circumference = 2 \times \pi \times r[/tex]

[tex]circumference = 2 \times \pi \times 7[/tex]

[tex]circumference = 14\pi[/tex]

Answer:

14π

Step-by-step explanation:

Given:

Radius of circle = 7 m

To determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.

Substitute the radius in the formula:

[tex]\implies 2\pi (r) = \text{Circumference}[/tex]

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

Simplify the circumference:

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

[tex]\implies 14\pi = \text{Circumference}[/tex]

Thus, the circumference is 14π.

what is the shaded part of the digestive (use 3. 14 as estimate for pi)

35 points for right answer

Answers

Answer:

Option A

Step-by-step explanation:

Area of shaded region

Square:

   Side = 12 m

Area of square = Side *side

                        = 12 *12

                         = 144 square m

Circle:

  diameter = side of the square

                  = 12 m

             r    = 12/2

                r = 6 m

  Area of circle = πr²

                         = 3.14 *6 * 6

                         = 113.04 m²

Area of the shaded part = area of square - area of circle

                                        = 144 - 113.04

                                        = 30.96 m²
