Answer:

The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

Answer:

x = 1 or x = -3/2

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + x - 3 = 0

The left hand side factors into a product with two terms:

(x - 1) (2 x + 3) = 0

Split into two equations:

x - 1 = 0 or 2 x + 3 = 0

Add 1 to both sides:

x = 1 or 2 x + 3 = 0

Subtract 3 from both sides:

x = 1 or 2 x = -3

Divide both sides by 2:

Answer: x = 1 or x = -3/2

The slope is 2 using the slope-intercept form. As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.

The slope of a line governs its steepness. Using mathematics, the gradient is expressed as "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical (rise) to the horizontal (run) change in distance between any two sites. Every time the equation for a straight line is written as y = mx + b, the slope-intercept representation of the equation is utilized. At the location of the y-intercept, the line has a slope of m, b, and c. (0, b). As an example, the y-intercept of the equation y = 3x - 7 has a value of 3. (0, 7).

given

The slope is 2 using the slope-intercept form.

As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.

Divide the difference in elevation between two points by the distance between them, multiply the result by 100, and that is the percent slope. The term "rise" refers to the elevational difference between two places. The run is the distance separating the points. The formula for percent slope is (rise / run) x 100.

lim x→−3 (x² − 9x + 3) is  39.

To find the limit of the function lim x→−3 (x² − 9x + 3), we will follow these steps:

Step 1: Identify the function
The given function is

f(x) = x² − 9x + 3.

Step 2: Determine the value of x that the limit is approaching
The limit is approaching x = -3.

Step 3: Evaluate the function at the given value of x
Substitute x = -3 into the function:

f(-3) = (-3)² − 9(-3) + 3.

Step 4: Simplify the expression
f(-3) = 9 + 27 + 3 = 39.

How do I solve for x in a equation?

Apply arithmetic operations to both sides of the equation to bring the variable to one side and all other values to the other side in order to find the value of x. To determine the outcome, simplify the values.

The size of the population after 3 months is approximately 129.3.

(a) Here's how to derive the formula for the population size after t months, given that the population is 5000 at t=0:

                               P'(t) = 200te^{-5t^2}P(t) = ∫P'(t) dt + C; (C is the constant of integration)

                      \(P(t) = ∫200te^{-5t^2} dt + CP(t) = -\frac{40}\)

    \({\sqrt{5\pi}}e^{-5t^2} + CP(0) = 5000;\)

since population is 5000 at t=0, we can substitute that into the formula above to get

                          \(5000 = -\frac{40}{\sqrt{5\pi}}e^{0} + C5000\)

               = \(= -\frac{40}{\sqrt{5\pi}} + C5000 + \frac{40}{\sqrt{5\pi}}\)

      = \(= CC = \frac{50000}{\sqrt{5\pi}}\)

Substitute C = \frac{50000}{\sqrt{5\pi}} into the formula for P(t) above:

                 \(P(t) = -\frac{40}{\sqrt{5\pi}}e^{-5t^2} + \frac{50000}{\sqrt{5\pi}}\)

(a) \(P(t) = -\frac{40}{\sqrt{5\pi}}e^{-5t^2} + \frac{50000}{\sqrt{5\pi}}\)

(b) To find the size of the population after 3 months, substitute t = 3 into the formula derived in part (a):

                      \(P(3) = -\frac{40}{\sqrt{5\pi}}e^{-5(3^2)} + \frac{50000}{\sqrt{5\pi}}\)

                 \(P(3) = -\frac{40}{\sqrt{5\pi}}e^{-45} + \frac{50000}{\sqrt{5\pi}}P(3) ≈ 129.3 (rounded off to one decimal place).\)

Thus, the size of the population after 3 months is approximately 129.3.

Answer:

Let x be the number of additional miles Tammy needs to run this week to reach her goal of at least 10 miles per week.

To determine the inequality, we can start with the given information and use the inequality symbol for "greater than or equal to" (≥):

4.5 + x ≥ 10

This inequality states that the sum of the distance Tammy has already run this week (4.5 miles) and the additional distance she still needs to run (x miles) must be greater than or equal to 10 miles in total for her to reach her goal.

To solve for x, we can start by subtracting 4.5 from both sides of the inequality:

x ≥ 10 - 4.5

Simplifying, we get:

x ≥ 5.5

Therefore, Tammy must run at least 5.5 more miles this week to reach her goal of at least 10 miles per week.

The correct trigonometric function cos²47° = (1 + cos94°)/2 thus, option (A) is correct.

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.

It is known that,

cos2x = 2cos²x - 1

2cos²x = 1 + cos2x

cos²x = (1 + cos2x)/2

Put x = 47°

cos²47° = (1 + cos94°)/2

Hence "The correct trigonometric function cos²47° = (1 + cos94°)/2".

Answer:

190 cards

Step-by-step explanation:

Elle, Jonah and Mandy shared the game cards in the ratio 2 : 3 : 7. The total ratio is:

2 + 3 + 7 = 12

If they were shared equally, they would each receive 152 cards, this means that the total number of cards they received is:

152 * 3 = 456 cards

Elle's share is therefore:

2 / 12 * 456 = 76 cards

Mandy's share is:

7 / 12 * 456 = 266 cards

Therefore, the number of cards that Many received more than Elle is:

266 - 76 = 190 cards

Answer:

35 metres

Step-by-step explanation:

The question states that A runs 25% faster than B. This means that, for every 1 second that B runs, A runs 1.25 second

Assuming that the total length of the race, that we're looking for, is D. Then we can say that B made a total distance of D-7 meters, and A runs D.

time taken by A = \(\frac{D}{1.25}\)

time taken by B = \(\frac{D-7}{1}\)

equating both together, we have

\(\frac{D}{1.25}\) = \(\frac{D-7}{1}\)

1.25D  - 8.75 = D

1.25D - D = 8.75

0.25D = 8.75

D = 8.75/0.25

D = 35

The problem states that a rectangular garden that measures 50 feet wide and 45 feet long is enclosed by a uniform width of x feet paved path. To solve the problem,

we can use the formula of the combined area of the garden and the paved path and equate it to 2646 square feet. The combined area is computed by adding the area of the garden and the area of the paved path.

Garden area:Length of garden = 45 ftWidth of garden = 50 ftArea of garden = Length x Width= 45 x 50= 2250 square feet

Paved path:

If the garden has a uniform width of x feet paved path, then the width of the paved path would be x + 2x + x= 4x. The width is multiplied by 2 because there are two widths surrounding the garden.

Length of paved path = length of garden + 2 (width of paved path)= 45 + 2 (4x)= 8x + 45Width of paved path = width of garden + 2 (width of paved path)= 50 + 2 (4x)= 8x + 50

The area of the paved path is computed by subtracting the area of the garden from the combined area.Area of paved path = Combined area - Garden area2646 square feet

= (8x + 45) (8x + 50) - 2250= 64x² + 760x + 675

We then solve for the value of x by factoring the quadratic equation.2646 square feet = 64x² + 760x + 6752646 - 2646

= 64x² + 760x + 675 - 264664x² + 760x - 1971
