What is the length of segment XY?​

Mathematics

Alexandra [31]3 years ago

Answer: Third option.

Step-by-step explanation:

You need to use the formula for calculate the distance between two points. This is:

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

You can observe in the graph that the coordinates of the point X and the point Y are the following:

X(-4,0) and Y(3,2)

Knowing this, you can substitute the coordinates into the formula.

You get that the lenght of the segment XY is:

 d_{(XY)}=\sqrt{(3-(-4))^2+(2-0)^2}\\\\d_{(XY)}=\sqrt{53}\ units

This matches with the third option.

Answer:

7.28 units to the nearest hundredth.

Step-by-step explanation:

Use the Pythagoras theorem.

If you examine the graph you see that the line segment is the hypotenuse of a right triangle with legs of length 2 and 7.

XY^2 = 2^2 + 7^2

XY^2 =  53

XY = √53

XY = 7.28.

1-tan^2(x)/sec^2 = cos(2x)
LekaFEV [45]

By applying the formula of trigonometric function the right hand side will

be equal to right hand side which is 1-tan^{2} x/sec^{2}x=cos2x.

Given: 1-tan^{2} x/sec^{2}x=cos2x.

Taking right hand side first which is cos2x.

We know that cos2x=1-tan^{2}x/1+tan^{2}x

Now we will solve the left hand side of the equation give which is

1-tan^{2} x/sec^{2}x

=1-tan^{2}x/1+tan^{2}x

[secant square x minus tangent square x is equal to 1]

By putting both values left hand side and right hand side we will find our solution which is :

1-tan^{2}x/1+tan^{2}x=1-tan^{2}x/1+tan^{2}x.

Hence proved

Use the drop-down menus to complete the statements to match the information shown by the graph. A graph has weight (pounds) on t
NISA [10]

Answer:

Your drop down menus have the following choices:

First box: faster than, slower than, at the same rate as.

Second box: greatest x-value, line, y-intercept, slope.

Third box: greater than, less than, equal to.

Fourth box: greatest x-value, x-intercept, y-intercept, slope, origin.

Fifth box: minutes per gallon, gallons per minute.

Pool A is filling up slower than Pool B because the slope of the graph of Pool A is less than that of the graph for Pool B.

The slope of the graph tells you the unit rate in gallons per minute.

Step-by-step explanation:

If you use the addition property of equality , what number would you add to both sides of the equal sign to isolate the variable
kkurt [141]

Answer:

The answer is "\frac{26}{7}"

Step-by-step explanation:

The whole question can be found in the file attached.

\to x + \frac{5}{7} = \frac{31}{7}\\\\

Subtracting the \frac{5}{7} from both sides of the equations:

\to x +\frac{5}{7}  - \frac{5}{7}  = \frac{31}{7}  - \frac{5}{7} \\\\

                    = \frac{31-5}{7} \\\\= \frac{26}{7} \\\\

Pls help for 50 points NO WEBSITES please help
Arlecino [84]

Answer:

Solution: 4\frac{3}{4}, 3.5, -15, 5

Not a solution: 129 and 10\frac{2}{3}

Step-by-step explanation:

20 ≥ 5 + 3x

3x + 5 ≤ 20

3x ≤ 20 - 5

3x ≤ 15

x ≤ 5

x must be LESS than or EQUAL to 5
