If the discriminant is negative then the quadratic has

Mathematics

zepelin [54]3 years ago
4 0

Answer:

No <em>real</em> solutions (or has two complex roots)

Step-by-step explanation:

The discriminant, <em>b</em>² - 4<em>ac</em>, is the expression (<u><em>radicand </em></u>) of the quadratic equation:

x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}.

The value of the discriminant determines the <u>nature</u> and the <u>number of solutions</u> given by the quadratic equation.

A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.

A lighthouse is 90 feet tall. A scale model of the lighthouse has a scale of 1 in: 6 ft. How tall is the model of the lighthouse
makkiz [27]

Answer:

15 inches tall

Step-by-step explanation:

To solve I would set up a ratio to visualize the question.

x in : 90 ft

1 in : 6ft

Then divide... 90 ÷ 6 = 15 ( this is the inches in the ratio that compares to 90 ft).

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 47.0 and 52.
Pavlova-9 [17]

Answer:

0.15 or 15%

Step-by-step explanation:

Since lengths are uniformly distributed, the probability that a class period runs between a two exact times is:

P(x_1\leq x \leq x_2)=\frac{x_2-x_1}{b-a}

In this case, a = 47.0 and b = 52.0 minutes.

The probability that a given class period runs between 50.25 and 51.0 minutes is:

P(50.25\leq x \leq 51.0)=\frac{51.0-50.25}{52-47} \\P(50.25\leq x \leq 51.0)=0.15=15\%

The probability is 0.15 or 15%.

Benji wrote the expression below to match the description "three less than the quotient of a number and nine" he wrote “3-n/9”ex
bulgar [2K]
Benji’s error is that the division should happen BEFORE subtracting 3. 3 should be subtracted from the quotient.

The correct response should be: (n/9)-3
