Given : number -3/4 - and  number line​

To Find :  represent -3/4 - on number line​

Solution:

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers  

On a number line the number increases as we move to the right and decreases as we move to the left.  

1 : Draw a line and mark some points at equal distance on it

Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3  and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

- 3/4

Divide number line between -1 & 0  in  4 Equal parts and go 3 part left of 0 to show - 3/4 on number line

The answer is the third choice because integers are whole numbers that can be positive, negative, or zero. -1.3, however, is not a whole number, so it is not an integer. The reason is the third choice as decimals and fractions are not integers. Hope it helps!

The requried domain of the given relation is {−5, 0, 3, 4}. Option A is correct.

The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.

Here,
We have the ordered pair of a relation given as,
(-5, -10), (0, 0) (3, 6) (4, 8)

From above, the x absciss of each ordered pair is termed as the domain of the relation.

So, set of domain = {−5, 0, 3, 4}]

The area inside the ellipse is π * 289.

To use Green's theorem to compute the area inside the ellipse, we can rewrite the given expression in a suitable form.

The equation provided: 1 * dA = dar * dy - y * dr + dy

We can rewrite this as: dA = dar * dy - y * dr + 2 * dy

Now, we can apply Green's theorem, which states:

∮C P dx + Q dy = ∬R (dQ/dx - dP/dy) dA

In our case, we have P = -y and Q = dar.

To find the area inside the ellipse, we need to evaluate the line integral ∮C P dx + Q dy. Since the given expression matches the form of ∮C P dx + Q dy, we can proceed with the computation.

The area inside the ellipse can be computed as:

A = 1/2 ∮C (-y dar + dar dy)

Now, we need to parameterize the ellipse and determine the limits of integration. Let's assume the equation of the ellipse is:

\(x^2/a^2 + y^2/b^2 = 1\)

In our case, since a = b = 17, the equation becomes:

\(x^2/17^2 + y^2/17^2 = 1\)

We can parametrize this ellipse using:

x = 17cos(t)

y = 17sin(t)

where t ranges from 0 to 2π

Substituting these parametric equations into the expression for the area, we have:

A = \(1/2 ∫[0, 2π] (-17sin(t) * 17cos(t) * 17sin(t) + 17cos(t) * 17sin(t) * 17cos(t)) dt\)

Simplifying the expression:

A = \(1/2 ∫[0, 2π] (-289sin^2(t) + 289cos^2(t)) dt\)

Since \(-sin^2(t) + cos^2(t)\) = 1, the expression simplifies further:

A = \(1/2 ∫[0, 2π] 289 dt\)

Integrating with respect to t:

A = 1/2 [289t] from 0 to 2π

A = 1/2 (289 * 2π - 0)

A = π * 289

Therefore, the area inside the ellipse is π * 289.

Answer:

b = 9 cm

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = \(\frac{1}{2}\) bh ( b is the base and h the height )

here h = 2b , then

\(\frac{1}{2}\) × b × 2b = 81

\(\frac{1}{2}\) × 2b² = 81

b² = 81 ( take square root of both sides )

b = \(\sqrt{81}\) = 9 cm

The required inequality expression is 8x + 6.50y ≤ 200

Maximum amount he can spend = $200

Cost of doll, = $6.50

Cost of car = $ 8.00

Mathematically, the maximum amount he can spend on restocking is cars and doll is :

(Cost of cars × number of cars) + (cost of doll × number of dolls) ≤ maximum amount

8x + 6.50y ≤ 200

Hence, the required inequality expression is : 8x + 6.50y ≤ 200

Recapturing a higher percent of marked alligators affects the estimated total population by making it high enough to support an accurate estimate.

This is referred to as the total number of species or organisms in an area at a given period of time.

Recapture rates are high enough to support an accurate estimate. The Lincoln-Peterson calculation tends to overestimate the population size, especially if the number of recaptures is small.

A protractor is a tool used to measure angles in degree. There are two basic types of protractors. One that measures 180º (half a circle). One that measures 360º (a full circle).

The slope of A'B' is 0 and the length of A'B' is 1/4(5) = 1.25 units.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

The line AB has the following coordinates.

A = (1, 4)

B = (6, 4)

The distance between AB is given as:

AB = √(6 - 1)² + (4 - 4)²

AB = √(5)²

AB = 5

The slope of AB = 0.

For the dilated rectangle the slope remains the same.

1. When the scientist started, there were 1.9477 thousand frogs

2. The frog population in month 17 is 1.2499 thousand frogs.

3.  The frog population will be above 400 frogs in 3rd month.

1. To find how many frogs were there when the scientist started, we need to find the population at month 0, which can be calculated by evaluating S(x) at x = 0:

\(S(0) =-0.0523 - 25(0)^2 + 6.34(0) + 2\)

         =  1.9477    

   Therefore, there were approximately 1.9477 thousand (1,947.7) frogs when the scientist started.

2. To find the approximate frog population in month 17, we need to evaluate S(x) at x = 17:

\(S(17) =-0.0523 - 25(17)^2 + 6.34(17) + 2\)

≈ 1.2499

   Therefore, the approximate frog population in month 17 is 1.2499 thousand (1,249.9) frogs.

3. To find the approximate frog population in month 17, we need to solve the equation S(x) = 0.4 (since S(x) is in thousands):

\(-0.0523 - 25x^2 + 6.34x + 2 = 0.4\)

Simplifying and rearranging, we get:

\(25x^2 - 6.34x + 2.4523 = 0\)

Using the quadratic formula, we can solve for x:

\(x = (-b \pm \sqrt{(b^2 - 4ac)}) / 2a\)

where a = 25, b = -6.34, and c = 2.4523

Plugging in the values, we get:

\(x = (-(-6.34) \pm \sqrt{((-6.34)^2 - 4(25)(2.4523))}) / 2(25)\)

x ≈ 2.56 or x ≈ 0.16

We can ignore the negative root since the population cannot be negative.

Therefore, the frog population will be above 400 frogs in approximately the 3rd month (since we started counting from x = 0).

To determine how much you should expect to pay for gas in Philadelphia versus Cleveland, we need to compare the transportation expenses in both cities. Based on the given data, the transportation expenses are as follows:

Philadelphia: $117

Cleveland: $106

To calculate the expected gas prices, we need to consider the transportation expenses relative to the national average. The formula to find the expected gas price is:

Expected Gas Price = National Average * (Transportation Expense / National Average)

National Average for gas = $2.59

For Philadelphia:

Expected Gas Price in Philadelphia = $2.59 * ($117 / 92) ≈ $3.30

For Cleveland:

Expected Gas Price in Cleveland = $2.59 * ($106 / 78) ≈ $3.51

Comparing the expected gas prices, we find that:

A. $3.03 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

B. $1.95 / $2.59: This option does not match the expected gas prices in Philadelphia and Cleveland.

C. $2.34 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

D. $2.75 / $3.24: This option matches the expected gas prices in Philadelphia and Cleveland.
