What are the roots of the quadratic function f(b) = b² – 75? Check all that apply.

November 23, 2024 by devyy

The roots of the quadratic function f(b) = b² – 75 can be found by solving the equation for when f(b) = 0. This leads us to: b² – 75 = 0 To find the roots, we can rearrange the equation to: b² = 75 Next, we take the square root of both sides: b … Read more

What happens to the sample variance when all values in a data set are identical?

November 23, 2024 by devyy

When all values in a data set are the same, the sample variance is equal to zero. To understand why this is the case, let’s first define what variance is. Variance measures the spread of data points in a data set. It quantifies how much the values deviate from the mean (average) of the data … Read more

What is the probability of drawing a heart or a 9 from a standard deck of cards?

November 23, 2024 by devyy

To calculate the probability of drawing a heart or a 9 from a deck of cards, we first need to understand the composition of a standard deck. A full deck contains 52 cards, which are split into 4 suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards. Among these, there are also 4 … Read more

How do you find the equation of the tangent line to the curve y = sin(x) at the given point (p, 0)?

November 23, 2024 by devyy

To find the equation of the tangent line to the curve y = sin(x) at a given point, we will perform the following steps: Determine the point of tangency: In this case, the point given is (p, 0), where we need to ensure that y = sin(p) should equal 0. For this to be true, … Read more

What is the value of b²-4ac for the equation x² + 5x + 4 = 0?

November 23, 2024 by devyy

To find the value of b² – 4ac for the quadratic equation x² + 5x + 4 = 0, we first need to identify the coefficients a, b, and c from the standard form of a quadratic equation, which is: ax² + bx + c = 0 From the given equation: a = 1 (coefficient … Read more

Can you provide an example of a function f(x) that has a domain of [0, 5] and a range of [0, 0]?

November 23, 2024 by devyy

To create a function f(x) that has a domain of [0, 5] and a range of [0, 0], we need to ensure that for every x in the domain, the output of the function is constrained to only one value—namely, 0. An example of such a function is: f(x) = 0 In this case, no … Read more

How do you completely factor the expression x^2 + 8x + 16?

November 23, 2024 by devyy

To completely factor the expression x2 + 8x + 16, we first need to identify if it can be factored into the product of two binomials. The approach we will take involves recognizing it as a perfect square trinomial. A perfect square trinomial takes the form (a + b)2 = a2 + 2ab + b2. … Read more

How can I find the values of f(3) and f'(3) if the tangent line to the curve y = f(x) at the point (3, 2) passes through the point (0, 1)?

November 23, 2024 by devyy

To solve for f(3) and f'(3), let’s start by understanding the situation with a tangent line. We know that the tangent line to the function y = f(x) at the point (3, 2) indicates that: 1. The value of the function at x = 3 is f(3) = 2. 2. The slope of the tangent … Read more
