Find the distance between points m(-4,6) and n(10,-5). round to the nearest tenth if necessary.

Answers

Answer 1

Answer: Use distance formula; $d = √((x_1-x_2)^2 + (y_1 - y_2)^2)$

You have $x_1 = -4$ , $x_2 = 10$ , $y_1 = 6$ , and lastly $y_2 = -5$

Plug in these values;

$d = √((-4-10)^2 + (6 - (-5))^2)$
$d = √((-14)^2 + (6 +5))^2)$
$d = √(14^2 + 11^2)$
$d = √(317)$
$d=17.8044938\ldots$
$d \approx \boxed{17.8}$

Question: Find the value of the sine for <A

C= 80m

B= 60m

A= ?

Well, since there are 3 sides you divide by three, only 2 sides are given so first add them,

80+60= 140

140/3= 46.6 also 46 6/10

Then divide by 62.13 because 140- 77.87 is that

It would lead you with 3/4

Simplify completely the quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.the quantity 3 times x to the third power plus 5 times x plus 2 all over x
3x3 + 5x + 2
3x2 + 5x2 + 2x
3x5 + 5x3 + 2x2

Answers

Answer:

(A) $3x^3+5x+2$

Step-by-step explanation:

To Simplify: The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Solution: The given statement can be easily rewritten as:

$The quantity 3 times x to the 4th power=3x^4$ ,

$5 times x to the 2nd power=5x^2$ and

$2 times x =2x$

Thus, according to the statement, the expression can be written as:

$(3x^4+5x^2+2x)/(x)$

⇒ $3x^3+5x+2$

which is the required simplified expression.

Thus,option A is correct.

C. 8x- 14y- 2z
D.8x -2y -3z

Answers

I believe the answer is B.
5+3=8
therefore being 8x
6-8=-2
therefore being -2y
-3+1=-2
there for being -2z
8x-2y-2z

What is the perimeter of a rhombus-shaped street sign with a 35-cm side? A. 280 cm
B. 140 cm
C. 1,225 cm
D. 70 cm

Answers

A rhombus has a total of 4 sides. All sides are equal. The formula of getting the perimeter of a rhombus is:
Perimeter = 4 * S
Perimeter = 4 * 35 cm
Perimeter = 140 cm.

So the perimeter of a rhombus-shaped street sign that has a 35-cm side is equal to (B) 140 cm.

Which of these units is a part of both U.S. and metric systems?A. Gram

B. Ounce - It is not metric unit.

C. Meter - It is not US or imperial unit. In imperial unit, its called miles.

D. Minute - Both the U.S. system and the metric system measure time in seconds, minutes, or hours.

The US imperial units are as follows - length in inches, feet and yards. Mass in pounds, ounces and stones. Volume in gallons.

Hello,
Gram is mksa(metric systems) maybe not in US

The figure below shows a line graph and two shaded triangles that are similar:Which statement about the slope of the line is true?
It is –2 throughout the line.
It is fraction negative 1 over 2 throughout the line.
The slope from point O to point A is one-half times the slope of the line from point A to point B. The slope from point O to point A is two times the slope of the line from point A to point B.

Answers

Answer:

The slope is fraction negative 1 over 2 throughout the line.

Step-by-step explanation:

The slope (m) of a line is computed as follows

m = (y2 - y1)/(x2 -x1)

where (x1, y1) and (x2, y2) are the coordinates of 2 points of the line. Taking, for example, points (0, 0) and (-4, 2), the slope is:

m = (2 - 0)/(-4 -0) = -1/2

Then, the slope is -1/2 throughout the line.

Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
