A line is a one-dimensional shape that is straight. The equation of the line that describes the shark's length is [tex]y = \frac{13}{3}x + 20\\[/tex].

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by:

[tex]y = mx + c[/tex]

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

Given when the shark was born the length of the shark was 20 inches, therefore, the coordinates can be written as (0,20).

Similarly, the length of the shark is 46 inches, while the age of the shark is 6 months. Therefore, the coordinates can be written as (6,46).

Now, the slope of the line can be written as,

m = (46-20)/(6-0) = 13/3

Now, the equation of the line can be written as  [tex]y = \frac{13}{3}x + c[/tex], further, substitute the value of any point in the equation of the line, therefore,

20=13/3(0)+c

c=20

Hence, the equation of the line that describes the shark's length is :

[tex]y = \frac{13}{3}x + 20\\[/tex].

Answer:

7 feet per second

Step-by-step explanation:

The change in elevation of the parachutist is -35 ft in 5 seconds. To find the change in elevation per second, we can divide the total change by the number of seconds.

Change in elevation per second = -35 ft / 5 seconds = -7 ft/s

So the parachutist's elevation changes by -7 ft/s each second.

It means the elevation of the parachute is decreasing by 7 feet per second.

Answer:

So the final solution is q < 9 and the inequality is False.

Step-by-step explanation:

To solve the given inequality, you first need to simplify the left-hand side of the inequality:

9 + 8 = 17

so the inequality becomes:

17 > 20 or 2q - 5 < 13

Since 17 is not greater than 20, this inequality is false.

Next, we need to solve the other inequality:

2q - 5 < 13

To isolate the variable on one side of the inequality, we need to add 5 to both sides:

2q < 18

Then, we divide both sides by 2:

q < 9

So the solution is q < 9

So the final solution is q < 9 and the inequality is False.

The prime numbers of 36 are 2 and 3 and the Prime factorization expression of 36 is equals to 2 × 2 × 3 × 3.

Prime factorization is a method of representing a number as a product of prime factors. A prime factor of a number is a factor that is prime. The numbers are called factors of 36 that divide 36 evenly. In other words, if we multiply two numbers and get the result equals to 36. So, factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. Steps for Prime Factorization of 36 :

Step 1: In first step, divide the number i.e., 36 by its smallest prime factor. So, by divisibility rules, 2 is the smallest prime factor of 36. So, we get, 36 ÷ 2 = 18

Step 2: Here need repeatedly divide the quotient by 2 until we get a number that is no more divisible by 2. So, we divide 18 again by 2 which is 18 ÷ 2 = 9.

Step 3 : Now, 9 is not completely divisible by 2, so, we proceed with the next prime factor of 36, which is 3. That is 9 ÷ 3 = 3

Step 5: Divide the quotient by 3 again which is 3 ÷ 3 = 1. Now, we need not proceed further as we have obtained 1 as our quotient. Therefore, the prime factorization of 36 is expressed as 2 × 2 × 3 × 3 = 2² × 3²; where 2 and 3 are prime numbers and the prime factors of 36.

The expressions that could be equivalent to x^2+bx-36 where b is negative is option 1: (x + 3)(x - 12) and option 5: (x - 9)(x + 4).

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is - x² + bx - 36

The first expression is - (x + 3)(x - 12)

Solve using the multiplication property -

= (x + 3)(x – 12)

= x(x - 12) + 3(x - 12)

= x² - 12x + 3x - 36

= x² - 9x - 36

The second expression is - (x - 2)(x + 18)

Solve using the multiplication property -

= (x - 2)(x + 18)

= x(x + 18) - 2(x + 18)

= x² + 18x - 2x - 36

= x² + 16x - 36

The third expression is - (x - 13)(x - 3)

Solve using the multiplication property -

= (x - 13)(x - 3)

= x(x - 3) - 13(x - 3)

= x² - 3x - 13x + 39

= x² - 16x + 39

The fourth expression is - (x + 4)(x + 9)

Solve using the multiplication property -

= (x + 4)(x + 9)

= x(x + 9) + 4(x + 9)

= x² + 9x + 4x + 36

= x² + 13x + 36

The fifth expression is - (x - 9)(x + 4)

Solve using the multiplication property -

= (x - 9)(x + 4)

= x(x + 4) - 9(x + 4)

= x² + 4x - 9x - 36

= x² - 5x - 36

Therefore, the choices for b being negative is x² - 5x - 36, and x² - 9x - 36.

A function is decreasing on some interval of its domain if f(a) < f(b) for all a, b in that interval such that a > b.

A function f(x) decreases on an interval I if f(b)<=f(a) for all b>a, where a,b in I. If f(b)<f(a) for all b>a, the function is said to be strictly decreasing. Conversely, a function f(x) increases on an interval I if f(b)>=f(a) for all b>a with a,b in I. If f(b)>f(a) for all b>a, the function is said to be strictly increasing. If the derivative f^'(x) of a continuous function f(x) satisfies f^'(x)<0 on an open interval (a,b), then f(x) is decreasing on (a,b). However, a function may decrease on an interval without having a derivative defined at all points. For example, the function -x^(1/3) is decreasing everywhere, including the origin x=0, despite the fact that the derivative is not defined at that point.

A function is increasing on some interval of its domain if f(a) > f(b) for all a, b in that interval such that a > b. A function is decreasing on some interval of its domain if f(a) < f(b) for all a, b in that interval such that a > b. More casually put: a function is increasing if the graph rises to the right.

The lowest positive whole number that should replace the question mark on the pinner such that the probability of pinning an odd number greater than 6 is 1/4 is 9.

It could be determined by calculating the probability of pinning an odd number greater than 6 out of the total number of possible outcomes.

If we consider the lowest positive whole number greater than 6 is 7, then we have 7,9,11,13,15,17,19,21,23,25 and so on.

Out of these numbers, 1/4 are odd numbers greater than 6. So the lowest whole number that could replace the question mark on the pinner is 9.

This is applicable for any situation where the probability of an event occurring out of a set of possible outcomes needs to be determined, and the lowest value for which that probability is a certain ratio needs to be found.

By evaluating and using the quadratic equation we will have:

1) 7 seconds.

2) Yes, it will pass.

3) 24.5 meters, after 3.5 seconds.

To find this, we need to solve the quadratic equation:

h = -2t^2 + 14t = 0

Taking t as a common factor we can write:

t*(-2t + 14) = 0

-2t +14 = 0

14 = 2t

14/2 = t

7 = t

The ball will be 7 seconds on the air.

2) To check this we need to evaluate the quadratic equation on t = 3

h = -2*3^2 + 14*3 = 24

The height is of the ball is larger than the height of the tree.

3) What is the maximum height of the ball?

This happens at the vertex of the quadratic equation:

h = -2t^2 + 14t

The two roots are t = 0 and t = 7, then the vertex is at t = (7 - 0)/2 = 3.5

- 25x + 30x = 200 - 175

5x = 25

x = 5

and

y = 200 - 150

y = 50

For the same amount of water we can write -

175 - 25x = 200 - 30x

- 25x + 30x = 200 - 175

5x = 25

x = 5 hours

Answer:

11 months

Step-by-step explanation:

It looks like you are trying to create a function that represents the number of members the fitness club has over time, assuming that each month they add 25 new members to the club.

You can use the function f(x) = 225 + 25x, where x represents the number of months from the current time.

The function starts with an initial value of 225 members, which represents the number of members the club already has. Then, for each additional month represented by x, the function adds 25 new members to the total, represented by 25x.

So, if the fitness club wants 500 members in 9 months, you can set f(9) = 500 and solve for x

f(9) = 225 + 25x = 500

25x = 500 - 225

25x = 275

x = 11

So, the club will reach 500 members in 11 months if they continue to add 25 members per month

The degree of the polynomial 2x² 5x² 7 is 4.

the arc angle KLI = 142°.

that means that the arc angle KJI = 360 - 142 = 218°.

this is twice the inscribed opposite angle on the arc (L).

so,

(a)

angle KLI = 218/2 = 109°

(b)

for the same reason

angle LKJ is half of the arc angle LIJ.

arc angle LIJ = 2× angle LKJ = 2×66 = 132°

that means

arc angle LKJ = 360 - 132 = 228°

angle LIJ = half of arc angle LKH = 228/2 = 114°

FYI for such an inscribed quadrilateral there is Akari the rule that the sum of opposite angles have to be 180°.

so, angle LIJ is opposite of angle LKJ.

27500 ≥ 120x + 12600 is the inequality that can be used to determine x, the great 120-kilogram crates that can be loaded onto the shipping container.

A relation that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. [1] Most frequently, size comparisons are made between two numbers on the number line. Different notations can be used to represent various kinds of inequalities, including:

A is smaller than b, as shown by the symbol a < b.

When the expression a > b is used, it means that a is greater than b.

The greatest weight that can be loaded into a container = 27500kg

Shipment weight already present in the container = 12400kg

Amount of weight that can be loaded = 27500 - 12400 = 15100kg

Weight of each crates = 120 kg

Let x be the maximum number of 120 kg crates that can be loaded to the container

Weight of 'x' number of 120 kg crates = 120x

Therefore, the required inequality is as follows

27500 ≥ 120x + 12600 (since the maximum amount of weight of crates that can be put in the container should be less than or equal to the total weight of the maximum number of crates that can be loaded into the container).
