Luis and his family flew 51487 miles last summer while on vacation rounded to the nearest thousand how many miles did they fly

1 answer:

8 0

In the given mathematical value of 51, 487 to round off this number to the nearest thousand, we can elaborate the number values using the expanded form to clearly see the order position: 1. 50, 000 = ten thousands 2. 1, 000 = thousands 3. 400 = hundreds 4. 80 = tens 5. 7 = ones Now we can observe the numerical value of 51, 487 than 1, 000 is the number in which belongs to the thousands’ position hence since the nearest number is 400 the value will be 51, 000.

I need help with this math problem. If you can please give me an explanation.

Serhud [2]

Answer:

see explanation

Step-by-step explanation:

Calculate the values of y by substituting the values of x into y = - 6x + 2

x = - 5 → y = - 6(- 5) + 2 = 30 + 2 = 32

x = - 1 → y = - 6(- 1) + 2 = 6 + 2 = 8

x = 0 → y = - 6(0) + 2 = 0 + 2 = 2

x = 1 → y = - 6(1) + 2 = - 6 + 2 = - 4

Thus

x y

- 5 32

- 1 8

0 2

1 - 4

Which of the following could be points on the unit circle: A. (4/3, 4/5) B. (5/13, 12/13)

IRINA_888 [86]

Answer:

Option (2) and (4) are correct.

$(\frac{5}{13},\frac{12}{13} )$ and $(\frac{6}{7},\frac{\sqrt{13}}{7} )$ are points on the unit circle.

Step-by-step explanation:

Given : Some points of circles.

We have to choose which points could be points on the unit circle.

We know, the equation of circle is

$x^2+y^2=r^2$ ..........(1)

where r is radius of circle.

We check each point for x and y values on the equation of circle and see which point gives radius = 1

Thus,

1) $(\frac{4}{3},\frac{4}{5} )$

Put in LHS of (1) , we have,

$(\frac{4}{3})^2+(\frac{4}{5})^2$

Simplify, we have,

$=\frac{16}{9}+\frac{16}{25}$

$=\frac{544}{225}\neq 1$

Thus, $(\frac{4}{3},\frac{4}{5} )$ is not a point on the unit circle.

2) $(\frac{5}{13},\frac{12}{13} )$

Put in LHS of (1) , we have,

$(\frac{5}{13})^2+(\frac{12}{13})^2$

Simplify, we have,

$=\frac{25}{169}+\frac{144}{169}$

$=\frac{169}{169}= 1$

Thus, $(\frac{5}{13},\frac{12}{13} )$ is a point on the unit circle.

3) $(\frac{1}{3},\frac{2}{3} )$

Put in LHS of (1) , we have,

$(\frac{1}{3})^2+(\frac{2}{3})^2$

Simplify, we have,

$=\frac{1}{9}+\frac{4}{9}$

$=\frac{5}{9}\neq 1$

Thus, $(\frac{1}{3},\frac{2}{3} )$ is not a point on the unit circle.

4) $(\frac{6}{7},\frac{\sqrt{13}}{7} )$

Put in LHS of (1) , we have,

$(\frac{6}{7})^2+(\frac{\sqrt{13}}{7})^2$

Simplify, we have,

$=\frac{36}{49}+\frac{13}{49}$

$=\frac{49}{49}= 1$

Thus, $(\frac{6}{7},\frac{\sqrt{13}}{7} )$ is a point on the unit circle.

Thus, $(\frac{5}{13},\frac{12}{13} )$ and $(\frac{6}{7},\frac{\sqrt{13}}{7} )$ are points on the unit circle.

What is the perimeter of triangle ABC round each step by the nearest 10th see image. Thanks so much

Greeley [361]

Perimeter of the triangle ABC is 18.7 units.

Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).

Length of the side AB = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$
