Answer:

${2x}^{3} - 3yz$

x=-1; y=-2 and z=3

$2 {( - 1)}^{3} - 3( - 2)(3)$

$- 2 +6(3)$

$- 2 +18$

(-)+(+)=(-)

$-16$

Selection D is the equivalent form of the given expression.

_____
The nominal annual interest rate in this problem is 40%. If it were compounded half-yearly, the formula would be x(1.2)^(2t) or x(1.44)^t. Apparently, this problem is more concerned with the equivalent form of the expression than it is with half-yearly compounding.

Apply the distributive property to factor out the greatest common factor. 35+50=35+50=?

a_sh-v [17]

Answer with explanation:

The given mathematical expression to solve : $35+50$

The prime factorization of each term can be written as follows :-

$35=5\times7$

$50=5\times5\times2$

We can see that the greatest common factor of both the terms = $5$

So we rewrite the given expression as :-

$5\times7+5\times10$

By using distributive property :-

$ab+ac=a(b+c)$ , we have

$=5(7+10)=5(17)=85$

Find the distance between the pair of points.

SVEN [57.7K]

Answer:

Distance is $\sqrt{290}$ units

Step-by-step explanation:

Use the distance formula which is $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ where $d$ is the distance between points $(x_1,y_1)$ and $(x_2,y_2)$

We are given that $(x_1,y_1)$ is $(-6,-23)$ and $(x_2,y_2)$ is $(-23,-24)$ , therefore the distance between the two points is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$d=\sqrt{(-23-(-6))^2+(-24-(-23))^2}$

$d=\sqrt{(-23+6))^2+(-24+23))^2}$

$d=\sqrt{(-17)^2+(-1)^2}$

$d=\sqrt{289+1}$

$d=\sqrt{290}$

Therefore, the distance between $(-6,-23)$ and $(-23,-24)$ is $\sqrt{290}$ units.

PLEASEEEEEEEEEEEEEEEEEEEEEE Edgar rolls two six-sided number cubes. What is the probability that he rolls a 2 on

elena55 [62]

The probability that Edgar rolls a 2 on the first cube and a number less than 5 on the second cube is 1/9. Thus, the correct option is C.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

There are a total of 36 outputs possible, while the number of desired outputs marked in the blue box is 4, therefore, the probability is,

Probability = 4/36 = 1/9

Hence, the probability that Edgar rolls a 2 on the first cube and a number less than 5 on the second cube is 1/9. Thus, the correct option is C.
