Mathematics
1 answer:
Alex Ar [27]3 years ago

Answer: using the discriminant to find the number of solutions to a quadratic equation b^2-4ac. positive discriminant indicates that the quadratic has <u>two distinct real number solutions.</u> The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Answer:

c

Step-by-step explanation:

c appears to be the better description as the line on the left has a solid circle at x = 1 indicating it is defined for x ≤ 1

While the line on the right has an open circle at x = 1 indicating it is defined for x > 1

Both line segments have a negative slope, thus

y = - 2x + 1 x > 1

y = - x + 2 : x ≤ 1

A right rectangular prism has edges of 8 feet, 4 feet, and 1/2 foot. How many cubes with side lengths of 1/2 foot would be neede
Ksenya-84 [330]

Answer:

Step-by-step explanation:

From the question we are told that

Edges of 8 feet, 4 feet, and 1/2 foot

Generally the volume V_p of the right rectangular prism is mathematically represented as

V_p=8*4*0.5

V_p=16

Generally volume of the cube V_c is mathematically given as

V_c =(\frac{1}{2})^3

V_c =\frac{1}{6}

Therefore total number of cubes is given as

V=\frac{V_p}{V_c}

V=\frac{16}{\frac{1}{6}}

V=96

Answer

Good question!

A. false. Even though 5 is usually greater than 2, in this case it is less because it is negative and positives are always greater than negatives.

B. true. Just like the last question, positives are always greater than negatives and even though 8 is usually greater than 3, in this case the 3 is a negative so it is less.

C. true. Think about which number is closer to the number line. When we are talking about negative numbers, the number closer to the number line is greater.

D. false. Same concept as the last question where -12 is closer to the number line than -12.5 so -12 is actually greater.

If you have any additional questions feel free to ask me or your teacher so you can really master what you're learning. :)
