Find the quadratic equation given the points (6,0), (-1,0), and (7,4).

h(x) = 1/2(x + 1)(x − 6)
h(x) = 2(x+6)(x − 1)
h(x) = 2(x + 1)(x - 6)
h(x):1/2(x+6) (x - 1)

When the base of a triangle is doubled, the height must be halved to maintain the same area. This is because the area of a triangle is proportional to the product of its base and height. Area of the new triangle is b₁h₂.

Given that a triangle has base b and height h, and the base is doubled. We need to find how the height must change so that the area remains the same.

The area of the original triangle is (1/2) b₁h₁.

Let's assume that the original base is b₁ and the original height is h₁.

Now, the base is doubled, so the new base is 2b₁.

Using the formula for the area of a triangle, we can find the area of the new triangle as

Area of the new triangle = (1/2) × base × height

= (1/2) × 2b₁ × h₂

= b₁h₂

where h₂ is the new height of the triangle.

Since we want the area of the new triangle to be equal to the area of the original triangle, we can equate the two expressions for the area

b₁h₁ = b₁h₂

Simplifying, we get

h₂ = h₁/2

Therefore, the height must be halved when the base is doubled to keep the area of the triangle constant.

The fraction representing Juan's age relative to Julia's age is -1/10. This means that Juan's age is one-tenth less than Julia's age.

Let's start by translating the given statement into an equation:

[tex]2/3J = 3/5 - 2/3Jl[/tex]

where J is Juan's age and Jl is Julia's age.

Now we can simplify this equation by first multiplying both sides by 15 (the least common multiple of 3 and 5) to get rid of the denominators:

[tex]10J = 9 - 10Jl[/tex]

Next, we can isolate J on one side of the equation by adding 10Jl to both sides:

[tex]10J + 10Jl = 9[/tex]

Finally, we can factor out a 10 from the left-hand side:

[tex]10(J + Jl) = 9[/tex]

Dividing both sides by 10, we get:

[tex]J + Jl = 9/10[/tex]

Now we can express Juan's age as a fraction of Julia's age by dividing both sides of this equation by Jl:

[tex]Jl/Jl + J/Jl = 9/10Jl[/tex]

Simplifying this, we get:

1 + J/Jl = 9/10

Subtracting 1 from both sides, we get:

[tex]J/Jl = 9/10 - 1[/tex]

[tex]J/Jl = -1/10[/tex]

In this scenario, the domain would be the set of all possible values for the amount of time it takes Sammy Speedster to drive from Houston to San Antonio. Since he is driving on a daily basis, the domain could be considered a continuous range from zero to some maximum value, perhaps 10 hours.

It's possible that Sammy could complete the trip in less than 3 hours if he were driving at a very high speed, but this would not be a common occurrence. Therefore, a reasonable domain could be considered to be between 3 and 10 hours.

The range, on the other hand, would be the set of all possible distances that Sammy could drive in the allotted time. Since we know that the distance is a constant 200 miles, the range would simply be 200 miles. It's possible that Sammy could drive more than 200 miles in a day if he were assigned additional routes, but this would not be relevant to this scenario.

The linear approximation of f(x) = ln(x) at x = 1 is L(x) = x - 1. Using this approximation, we can estimate ln(1.16) to be approximately 0.16.

The formula for the linear approximation of a function f(x) at a point x = a is given by L(x) = f(a) + f'(a)(x - a), where f'(a) is the derivative of f(x) evaluated at x = a.

In this case, f(x) = ln(x), so f'(x) = 1/x by the derivative of natural logarithm.

We are asked to find the linear approximation of f(x) = ln(x) at x = 1, so a = 1 in the formula.

Plugging in the values, we get L(x) = ln(1) + 1( x - 1) = x - 1.

Now, we can use this linear approximation L(x) = x - 1 to estimate ln(1.16) by plugging in x = 1.16, as given in the question.

L(1.16) = 1.16 - 1 = 0.16, which is our estimated value for ln(1.16) using the linear approximation.

the velocity vector of the object is v(2) = 3i + j + k, the speed is sqrt(11), and the acceleration vector is a(t) = (1/2)k.

We're given the position vector and time and asked to find the velocity vector, speed, and acceleration vector of the object. Let's solve this step-by-step.

1. Differentiate the position vector with respect to time (t) to find the velocity vector:
Position vector: r(t) = 3ti + tj + (1/4)t^2k

Velocity vector: v(t) = dr(t)/dt = d(3ti)/dt + d(tj)/dt + d((1/4)t^2k)/dt

v(t) = 3di/dt + dj/dt + (1/2)tk

v(t) = 3i + j + (1/2)tk

2. Plug in the given time (t = 2) into the velocity vector to find the velocity at that time:
v(2) = 3i + j + (1/2)(2)k

v(2) = 3i + j + k

3. Find the speed by calculating the magnitude of the velocity vector:
Speed = |v(2)| = sqrt((3^2) + (1^2) + (1^2))

Speed = sqrt(9 + 1 + 1)

Speed = sqrt(11)

4. Differentiate the velocity vector with respect to time (t) to find the acceleration vector:
Acceleration vector: a(t) = dv(t)/dt = d(3i)/dt + d(j)/dt + d((1/2)tk)/dt

a(t) = 0i + 0j + (1/2)k

So, the velocity vector of the object is v(2) = 3i + j + k, the speed is sqrt(11), and the acceleration vector is a(t) = (1/2)k.

The piecewise defined function for fencing the backyard would be 30(300) + 25(x - 300), if x > 300, or 30x, if 0 < x ≤ 300, as seen below.

A piecewise defined function is a function that is defined by different formulas on different intervals or "pieces" of its domain. This means that the formula used to calculate the output (the function value) of the function depends on the value of the input (the independent variable).

For this particular question, let C be the cost of fencing a backyard and let x be the length of the fence in feet. Then, we can write the piecewise defined function as:

C(x) =  30x, if 0 < x ≤ 300 OR

C(x) = 30(300) + 25(x - 300), if x > 300

In other words, if the length of the fence is less than or equal to 300 feet, the cost is simply 30 times the length of the fence. If the length of the fence is greater than 300 feet, the cost is the cost of the first 300 feet (30 times 300), plus 25 times the additional length of the fence beyond 300 feet.

The critical numbers of f(x) = -2x^3 + 39x^2 - 240x + 2 are A = 5 and B = 8.

To find the critical numbers of a function, we need to find the values of x where the derivative of the function is zero or undefined.

For the function f(x) = 5x^2 + 7x - 10, the derivative is:

f'(x) = 10x + 7

To find the critical numbers, we need to set f'(x) = 0 and solve for x:

10x + 7 = 0

10x = -7

x = -7/10

So the critical number of f(x) = 5x^2 + 7x - 10 is x = -7/10.

For the function f(x) = -2x^3 + 39x^2 - 240x + 2, the derivative is:

f'(x) = -6x^2 + 78x - 240

To find the critical numbers, we need to set f'(x) = 0 and solve for x:

-6x^2 + 78x - 240 = 0

We can simplify this equation by dividing both sides by -6:

x^2 - 13x + 40 = 0

Now we can factor the quadratic:

(x - 5)(x - 8) = 0

So the solutions are x = 5 and x = 8.

To determine which critical point is A and which is B, we need to check the sign of the second derivative of f(x) at each critical point.

The second derivative of f(x) is:

f''(x) = -12x + 78

Plugging in x = 5, we get:

f''(5) = -12(5) + 78 = 18

Since f''(5) is positive, we know that f(x) has a local minimum at x = 5. Therefore, x = 5 is the critical point A.

Plugging in x = 8, we get:

f''(8) = -12(8) + 78 = -6

Since f''(8) is negative, we know that f(x) has a local maximum at x = 8. Therefore, x = 8 is the critical point B.

Therefore, the critical numbers of f(x) = -2x^3 + 39x^2 - 240x + 2 are A = 5 and B = 8.

Step-by-step explanation:

Ms. Smith and Mr. Brown's attendance count had an absolute error of 1.5 people. This means that the measured value was 1.5 people off from the actual value, which was between 96 and 105.

The absolute error is a measure of the difference between the actual value and the measured value. In this case, Ms. Smith and Mr. Brown took attendance at a fire drill and the actual count of students and teachers was between 96 and 105. Let's say they counted 100 people in total.

To find the absolute error, we need to subtract the measured value from the actual value. In this case, the absolute error would be |100 - 98.5| = 1.5, where 98.5 is the midpoint between 96 and 105.

This means that the attendance count was off by 1.5 people. It is important to note that absolute error is always positive and represents the magnitude of the difference between the actual and measured values.

The absolute error  is 0.5.

How to calculate absolute error range?

The absolute error is a measure of how far away a given estimate is from the actual value. In this case, we know that the actual count of students and teachers was between 96 and 105, but we don't know the exact number. Let's assume that Ms. Smith and Mr. Brown recorded the number of students and teachers as 100.

The absolute error is then calculated by taking the absolute value of the difference between the estimate and the actual value. In this case, the estimate is 100 and the actual value is somewhere between 96 and 105. So, the absolute error would be the difference between 100 and the midpoint between 96 and 105.

The midpoint between 96 and 105 is (96 + 105)/2 = 100.5. Therefore, the absolute error would be |100 - 100.5| = 0.5. So the absolute error in this case is 0.5.

All angles of a triangle add up to 180 degrees.

Two angle measures are provided, 100 and 35 (?)

Add up the two to get 135, and subtract from 180

180 - 135 = 45 degrees.

I might be seeing the rightmost angle measure wrong but I think it's 35, if it's not you can still apply the same strategy, just add the two given angles and subtract that from 180 to find x.

The perimeter of an isosceles right triangle whose short sides have that length 0.75 units is 2.56 units.

Given that, an isosceles right triangle whose short sides have that length 0.75 units.

Let the longest side be x.

Here, x²=0.75²+0.75²

x²=1.125

x=√1.125

x=1.06 units

Now, the perimeter = 0.75+0.75+1.06

= 2.56 units

Therefore, the perimeter of an isosceles right triangle whose short sides have that length 0.75 units is 2.56 units.
