The shape of the graph b will be linear with an immediate decrease in speed.
What is a position vs time graph?In Mathematics, a position vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled by an object from its starting position with respect to the time when it is started moving.
Generally speaking, the position or distance traveled by a physical object in a position vs time graph is always plotted on the y-coordinate while time is always plotted on the x-coordinate (x-axis).
In this scenario, the rate of change of the shape's position can be calculated as follows:
Rate of change = (30 - 50)/(40 - 30)
Rate of change = -20/10
Rate of change = -2.

In the figure below, B is between A and C, and C is between B and D. If AD=13, BD=7, and BC=3, find AC.
AC =
The length of segment AC is equal to 9.
How to Find the Length of a Segment?Since B is between A and C, we can use the fact that AB + BC = AC. Similarly, since C is between B and D, we can use the fact to state the lengths of the following segments that: CD + BC = BD.
Substituting the given values, we get:
AB + BC = AC
CD + BC = BD
We are given segments BD = 7 and BC = 3, so we can substitute these values:
CD + 3 = 7
Solving for CD, we get:
CD = 7 - 3
CD = 4
Now we can use the fact that AD = AC + CD to solve for the length of segment AC:
AD = AC + CD
13 = AC + 4
AC = 9

For some value of b, the expression 3(5x - 1) + b(2x - 7) is a constant. What is the constant?
The value of the expression as a constant is 49.5
How to determine the constantFrom the question, we have the following parameters that can be used in our computation:
3(5x - 1) + b(2x - 7)
For the expression to be a constant, the following must be true
b(2x) = -3(5x)
Divide by x
b(2) = -3(5)
Divide by 2 and remove bracket
b = -7.5
Substitute the known values in the above equation, so, we have the following representation
3(5x - 1) -7.5(2x - 7)
So, we have
15x - 3 - 15x + 52.5
Evaluate the like terms
49.5
Hence, the constant is 49.5

Can someone help me find the point of intersection for:
2500(1. 25)^t=6000(0. 3)^t
algebraically? thank you.
The point of intersection can be found by setting the equations equal, dividing by the same quantity, taking the natural log, and dividing by ln(1.25).
[tex]2500(1.25^t) = 6000(0.3^t)[/tex]
[tex]2500*1.25^t = 6000*0.3^t[/tex]
Divide both sides by 2500:
[tex]1.25^t = 0.3^t * (6000/2500)[/tex]
Divide both sides by[tex]0.3^t[/tex]:
[tex]1.25^t / 0.3^t = (6000/2500) / 0.3^t[/tex]
Take the natural log of both sides:
[tex]t*ln(1.25) = ln((6000/2500) / 0.3^t)[/tex]
Divide both sides by ln(1.25):
[tex]t = ln((6000/2500) / 0.3^t) / ln(1.25)[/tex]
The point of intersection is t = ln((6000/2500) / [tex]0.3^t[/tex]) / ln(1.25).
The point of intersection of two exponential functions can be found algebraically by setting the two equations equal to each other and solving for the variable t. For example, if we want to find the point of intersection of [tex]2500(1.25^t) = 6000(0.3^t)[/tex], we can start by setting the two equations equal to each other and dividing both sides by [tex]2500: 1.25^t = 0.3^t * (6000/2500)[/tex]. Then we can divide both sides by[tex]0.3^t: 1.25^t / 0.3^t = (6000/2500) / 0.3^t[/tex]. We then take the natural log of both sides: [tex]t*ln(1.25) = ln((6000/2500) / 0.3^t)[/tex]. Finally, we divide both sides by ln(1.25): [tex]t = ln((6000/2500) / 0.3^t) / ln(1.25)[/tex]. This means that the point of intersection is[tex]t = ln((6000/2500) / 0.3^t) / ln(1.25).[/tex] In conclusion, the point of intersection of two exponential functions can be found algebraically by setting the two equations equal to each other, dividing both sides by the same quantity, taking the natural log of both sides, and then dividing both sides by ln(1.25).

Please help me
Answer:
x ≈ 40.6
Step-by-step explanation:
using the sine ratio in the right triangle
sin38° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{25}{x}[/tex] ( multiply both sides by x )
x × sin38° = 25 ( divide both sides by sin38° )
x = [tex]\frac{25}{sin38}[/tex] ≈ 40.6 ( to 1 decimal place )
Answer:
x ≈ 40.6 units
(nearest tenth / one decimal place)
Step-by-step explanation:
You can use the law of sines in this situation since you know it is a right triangle because of the right angle, and you have an angle and a corresponding side.
Given this information, you can use the equation:
sin A / a = Sin B / b = Sin C / c
Given: A is 38°, a is 25, C is 90°.
Find: x which is side c
sin A / a = Sin B / b = Sin C / c →
[Substitute the information given]
Sin (38°) / 25 = Sin (90°) / c →
[Use the basic identity of sin(90°)]
Sin (38°) / 25 = 1 / c →
[Use the reciprocal rule]
25 / Sin(38°) = c →
[Rotate the equation]
c = 25 / Sin(38°) →

After 412 years there will be no trees at the state park.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
From the given information,
Slope(m) = (42 - 48)/(5 - 0).
Slope(m) = - 6/5.
b = 48, As y-intercept(0, 48).
Therefore, y = - (6/5)x + 48.
Now, y = - (6/5)×412 + 48.
y = - 446.4 trees per acre, But there will be no trees as it came out to be a negative value.

What is the complete square corresponding to x2 – 6x? A. (x – 1.5)2 B. (x – 3)2 C. (x – 4.5)2 D. (x – 9)
Answer:
So the answer is C. (x - 3)^2.
Step-by-step explanation:
The complete square corresponding to x^2 - 6x is (x - 3)^2.
A complete square is a trinomial that can be written in the form (x - a)^2, where a is a constant. To find the complete square of x^2 - 6x, we need to rewrite x^2 - 6x into the form (x - a)^2. We do this by adding and subtracting a constant term to make the trinomial a perfect square.
x^2 - 6x + 9 = (x - 3)^2
So the answer is C. (x - 3)^2.
8. the weights of cows offered at an auction in one region are normally distributed with a mean of 825.0 pounds and a standard deviation of 74.8 pounds. one cattleman only wants to bid on cows that are in the top 5% of weight. what is the lowest weight cow that the cattleman should bid on
The cattleman should bid on cows that weigh at least 944.0 pounds, which is the weight corresponding to the top 5% of the normally distributed weights of cows.
To determine the lowest weight cow that the cattleman should bid on, we need to find the weight that corresponds to the top 5% of the weight distribution.
Using the standard normal distribution, we can find the z-score that corresponds to the top 5% of the distribution as follows:
z = invNorm(0.95) ≈ 1.645
where invNorm is the inverse of the standard normal cumulative distribution function, which can be found using a statistical calculator or a standard normal distribution table.
Next, we can use the z-score formula to convert the z-score to a weight value:
z = (x - μ) / σ
Solving for x, we get:
x = z * σ + μ
Substituting the values given in the problem, we get:
x = 1.645 * 74.8 + 825.0
x ≈ 944.0 pounds
Therefore, the cattleman should bid on cows that weigh at least 944.0 pounds.

What exactly is integration?
The process of computing an integral is known as integration. Mathematicians utilise integrals to compute a variety of useful quantities such as areas, volumes, displacement, and so on. When we talk about integrals, we usually imply definite integrals. Antiderivatives are represented by indefinite integrals. Integration, along with differentiation, is one of the two major calculus concepts in mathematics (which measure the rate of change of any function with respect to its variables).
Integral Fundamental
A definite integral is one that has both upper and lower bounds. For X to lie, only a true line may be utilised. The Definite Integral is also known as a Riemann Integral.
From a to b, use ∫f(x)dx
indefinite integral
Integrals are defined without upper and lower limits. It looks like this:
A indefinite Integral is written as:
∫f(x)dx = F(x) + C
Where C might be any constant and the function f(x) is referred to as the integrand.
Now,
As given in image
Area of the region will be =∫3x-6 dx from x=2 to 2.8 +∫-2x+8 from x=2.8 to 4.
=(3x²/2-6x) from x=2 to 2.8 + (-2x²/2+8x) from x=2.8 to 4.
=3*0.8*0.8/2-6*0.8-2*1.2*1.2+8*1.2
=2.88 sq units.
Hence,
The area of the region between line y =3x -6 and line y=-2x+8 and the x-axis with the help of integration will be 2.88 sq units.
