Answer:

Step-by-step explanation:

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve

Answer:

12 units

Step-by-step explanation:

Applying the distance formula, $\sqrt{(x_{2}- x_{1})^{2} + (y_{2}- y_{1})^{2} }$ , you get $\sqrt{(2-2)^{2} +(4+8)^{2}}$ = $12$ units.

You are randomly selecting 3 cans of regular and diet cola, but assume that there are 6 cans of regular cola and 7 cans of diet

gayaneshka [121]

Answer:0.367

Step-by-step explanation:

Given

There are 6 cans of regular and 7 cans of diet cola

number of ways of selecting 2 regular colas and 1 can of diet cola is

$\Rightarrow ^6C_2\times ^7C_1$

The total no of ways of selecting 3 items out of 13 items is

$\Rightarrow ^{13}C_3$

Probability is

$\Rightarrow P=\dfrac{^6C_2\times ^7C_1}{^{13}C_3}=\dfrac{105}{286}\\\Rightarrow P=0.367$

In the diagram below, quadrilateral ABCD is inscribed in a circle. What is the measure of angle D?

grin007 [14]

Given:

In the circle P, ABCD is inscribed quadrilateral.

And, ∠DAB = 110°, ∠ABC = 72°

To find the value of ∠ADC.

Theorem:

A quadrilateral can be inscribed in a circle if and only if the opposite angles are supplementary [ sum of the opposite angles will be 180°]

According to the theorem,

$\angle ABC+\angle ADC = 180^{\circ}$

$\angle ADC +72^{\circ} = 180^{\circ}$

$\angle ADC = 180^{\circ}-72^{\circ}$

$\angle ADC = 108^{\circ}$

Hence,

The value of ∠ADC is 108°.

Hence, Option b is the correct answer.
