Nasreen was babysitting her cousin on Saturday.
She brought him to the park and spent $4.25 at
the ice cream truck. If she was paid $30.00 for
babysitting, how much did Nasreen profit for the
afternoon?

using the pythago theory:

c^2 = a^2 + b^2

=> 25^2 = 24^2 + b^2

=> b = √(25^2 - 24^2)

=> b = √(625 - 567) = √49 = 7

Answer:

The answer is Multiplication.

Step-by-step explanation:

The coefficient of the x term in f(x) is 2, and the coefficient of the x term in g(x) is 2. When we add or subtract the two functions, the coefficient of the x term remains 2. However, when we multiply the two functions, the coefficient of the x term becomes 4. Therefore, multiplication results in the largest coefficient on the x term.

Here is the solution for each of the operations:

Addition: f(x) + g(x) = (2x −1) + (2x + 4) = 4x + 3

Subtraction: f(x) - g(x) = (2x −1) - (2x + 4) = -5

Multiplication: f(x) * g(x) = (2x −1) * (2x + 4) = 4x^2 + 6x - 4

As you can see, the coefficient of the x term in f(x) * g(x) is 4, which is larger than the coefficients of the x terms in f(x) + g(x) and f(x) - g(x). Therefore, multiplication results in the largest coefficient on the x term.

Data sharing with the remainder of the lab section has a number of benefits. First of all, it broadens the sample size overall, which can boost the statistical power of analyses and broaden the applicability of the results.

It is simpler to find significant effects or relationships in the data when the sample size is higher. Furthermore, combining data can result in a more representative sample, minimising any biases that can be present in smaller individual datasets. Collaboration and the investigation of trickier research problems are made possible by sharing data. It promotes information exchange and a collaborative atmosphere where researchers can benefit from one another's experiences, approaches, and insights, thereby raising the calibre and dependability of the research carried out in the lab sector.

The curvature of the curve r(t) = (t, t, 1+t²) at the point (2, 2, 5) as 1/12.

Given:

r(t) = (t, t, 1+t²) at the point (2, 2, 5). We must find the curvature of r(t) at the point (2, 2, 5). Curvature is the rate at which a curve changes its direction at a particular point on the curve. It measures how much a curve deviates from being a straight line.

The formula to find the curvature of a curve is given by:

K = |T'(t)| / |r'(t)| where T'(t) is the derivative of T(t), and r'(t) is the derivative of r(t) to t.

Let's find the curvature of the given curve r(t). The curve is defined by r(t) = (t, t, 1+t²).

Taking the derivative of the curve, we get:

r'(t) = (1, 1, 2t)

Taking the second derivative, we get:

r''(t) = (0, 0, 2). Now we can find the unit tangent vector as:

T(t) = r'(t) / |r'(t)|

= (1/√2, 1/√2, 1/√2t)

The derivative of T(t) is:

T'(t) = (0, 0, 1/2t√2). So the curvature of the curve at point (2, 2, 5) is:

K = |T'(t)| / |r'(t)|K

= |(0, 0, 1/2t√2)| / |(1, 1, 2t)|K

= |1/2t√2| / √(1 + 1 + 4t²)

Putting t = 2, we get:

K = |1/4√2| / √(1 + 1 + 16)

K = |1/4√2| / √18

K = |1/4√2| / 3√2

K = 1 / 12

We found the curve's curvature at points (2, 2, 5) using the formula. Therefore, the curvature of the curve r(t) = (t, t, 1+t²) at the point (2, 2, 5) is 1/12.

ANSWER:

The sum of the series 2 + 4 + 6 + 58 can be expressed using sigma notation as Σ(i = 1 to 4) 2i, which simplifies to 20.

The first term of the series is 2, the second term is obtained by adding 2 to the first term (2 + 2 = 4), the third term is obtained by adding 2 to the second term (4 + 2 = 6), and so on. Finally, the last term of the series is 58.

Now, let's express this series using sigma notation:

Σ(i = 1 to n) 2i

In the above notation, the Greek letter sigma (Σ) represents the sum. The variable i is the index of summation, which starts at 1 and goes up to n. In this case, n represents the number of terms in the series.

The expression 2i represents the terms of the series. As i increases from 1 to n, the value of 2i increases accordingly. For example, when i = 1, 2i = 2. When i = 2, 2i = 4, and so on.

To find the sum of the series using sigma notation, we substitute the values of the index of summation into the expression 2i and add up the terms:

Σ(i = 1 to n) 2i = 2(1) + 2(2) + 2(3) + ... + 2(n)

For our specific series, we have:

Σ(i = 1 to 4) 2i = 2(1) + 2(2) + 2(3) + 2(4)

Simplifying this expression, we get:

2 + 4 + 6 + 8 = 20

The value x of given linear equation in one variable is \(13\)

To solve for x in the equation \(4x-1 +3x -1 +7x = 180\), we first need to combine the like terms on the left side:

\(4x-1 +3x -1 +7x = 180\)

Next, we can isolate the variable term by adding \(2\) to both sides:

\(14x -2 +2 = 180+2\\14x = 182\)

Finally, we can solve for x by dividing both sides by \(14\):

\(x = \frac{182}{14}\)

This can be simplified by dividing both the numerator and denominator by their greatest common factor, which is \(14\):

\(x = 13\)

Therefore, the value of \(x\) that satisfies the equation \(4x-1 +3x -1 +7x = 180\) is \(x = 13\)

The required blank space could be filled with 20% as, If the chance of getting a disease is 20 out of 100, this would be the same as having a 20% chance.

Given that,
If the chance of getting a disease is 20 out of 100, this would be the same as having a ______ % chance, to determine what value can be put.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

The net of the display consists of one rectangle and two right triangles.  168 ft² is needed to make a display case. Hence option D is the correct option.

What is surface area?

The size of a patch on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

The surface area of the triangular prism is the display area of the glass.

The surface area of a triangular prism consists of one rectangle and two right triangles.

The length of the rectangle is (10ft + 6 ft + 8ft) = 24ft.

The width of the rectangle is 5 ft.

The area of a rectangle is the product of length and width.

The area of the rectangle is 24ft × 5ft = 120 square ft

The length of the base of the triangle is 8 ft and the height is 6ft

The area of the triangle is 1/2 × base × height = 1/2 × 8 × 6 = 24 square ft

The display area is 120 square ft + 2 ×24 square ft = 120 + 48 = 168 ft².

The midpoint of the segment PQ where P¨= (-4, -1) and Q = (3, 3) is the point  (-1/2, 1)

If we have a segment whose endpoints are (a, b) and (c, d), then the midpoint of that segment will be:

( (a + c)/2, (b + d)/2).

In this case, we can see that the endpoints of the segment are:

(-4, -1) and (3, 3), replacing that in the midpoint formula that I wrote above we will get:

Midpoint: (  (-4 + 3)/2 , (-1 + 3)/2) = (-1/2, 1)
