Line Y X is drawn with point Y at (3, 0) and passes through (0, 3). Line Z W is drawn with point Z at (0, negative 3) and point W at (negative 4, 1). LIne Z Y is drawn with point Y at (3, 0) and point Z at (0, negative 3). Which statements are true about the lines? Select three options. Line WZ has the same slope as line XY. Line YX has a greater slope than line ZY. Line XW has a lesser slope than line YZ. Line ZW has the same y-intercept as line YZ. Line XY has a lesser y-intercept than line XW.
Answer» Given: Line XW is drawn with point W at (- 4, 1) and passes through (0, 2) Line YX is drawn with point Y at (3, 0) and passes through (0, 3) Line ZW is drawn with point Z at (0, - 3) and point W at (- 4, 1) Line ZY is drawn with point Y at (3, 0) and point Z at (0, - 3) To find: The correct optons out of - Line WZ has the same SLOPE as line XY. Line YX has a greater slope than line ZY. Line XW has a lesser slope than line YZ. Line ZW has the same y-intercept as line YZ. Line XY has a lesser y-intercept than line XW. Answer: The equation of a STRAIGHT line with coordinates (x1,y1), (x2,y2) is - $y - y1 = \frac{y2 - y1}{x2 - x1} (x - x1)$ -(1) where the slope is [y2 - y1/ (x2 - x1)] Thus from equation (1), the equations of the lines are - XW - y - 1 = (1/2) (x +4) XY - y = -1 (x - 3) ZW - y + 3 = -1 (x) ZY - y = 1 (x - 3) Thus, the correct options are - Line WZ has the same slope as line XY. Line XW has a lesser slope than line YZ. Line ZW has the same y-intercept as line YZ. Line XY has a lesser y-intercept than line XW

Four lines are drawn on a coordinate plane to form trapezoid WXYZ. A coordinate grid with 4 lines. Line X W is drawn with point W at (negative 4, 1) and passes through (0, 2) with and (3, 3). Line Y X is drawn with point Y at (3, 0) and passes through (0, 3). Line Z W is drawn with point Z at (0, negative 3) and point W at (negative 4, 1). LIne Z Y is drawn with point Y at (3, 0) and point Z at (0, negative 3). Which statements are true about the lines? Select three options. Line WZ has the same slope as line XY. Line YX has a greater slope than line ZY. Line XW has a lesser slope than line YZ. Line ZW has the same y-intercept as line YZ. Line XY has a lesser y-intercept than line XW.

Answer»

Given:

Line XW is drawn with point W at (- 4, 1) and passes through (0, 2)
Line YX is drawn with point Y at (3, 0) and passes through (0, 3)
Line ZW is drawn with point Z at (0, - 3) and point W at (- 4, 1)
Line ZY is drawn with point Y at (3, 0) and point Z at (0, - 3)

To find:

The correct optons out of -

Line WZ has the same SLOPE as line XY.
Line YX has a greater slope than line ZY.
Line XW has a lesser slope than line YZ.
Line ZW has the same y-intercept as line YZ.
Line XY has a lesser y-intercept than line XW.

Answer:

The equation of a STRAIGHT line with coordinates (x1,y1), (x2,y2) is -

$y - y1 = \frac{y2 - y1}{x2 - x1} (x - x1)$ -(1)

where the slope is [y2 - y1/ (x2 - x1)]

Thus from equation (1), the equations of the lines are -

XW - y - 1 = (1/2) (x +4)
XY - y = -1 (x - 3)
ZW - y + 3 = -1 (x)
ZY - y = 1 (x - 3)

Thus, the correct options are -

Line WZ has the same slope as line XY.

Line XW has a lesser slope than line YZ.

Line ZW has the same y-intercept as line YZ.

Line XY has a lesser y-intercept than line XW

find the cost of fencing rectangular park of length 175 m and breadth 150m at the rate of ₹ 12 per meter.

Answer»

❏ Question:-

FIND the cost of FENCING rectangular park of length 175 m and breadth 150m at the rate of ₹ 12 PER meter.

❏ Solution:-

$\setlength{\unitlength}{0.78 cm}\begin{picture}(12,4)\thicklines\put(5.6,9.1){$A$}\put(5.5,5.8){$B$}\put(11.1,5.8){$C$}\put(11.05,9.1){$D$}\put(4.5,7.5){$150\:m$}\put(8.1,5.3){$175\:m$}\put(11.5,7.5){$150 \:m$}\put(8.1,9.5){$175\:m$}\put(6,6){\line(1,0){5}}\put(6,9){\line(1,0){5}}\put(11,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\end{picture}$

✏ Given:-

length =175 m.
breadth = 150 m.

✏ To Find:-

•cost of fencing at the rate of 12 Rs /metre.

✏ Explanation :-

$\sf\implies Perimeter=2\times(length+breadth)$

$\sf\implies Perimeter=2\times (175+150)\:m$

$\sf\implies Perimeter=2\times 325\:m$

$\sf\implies \boxed{\red{\large{Perimeter=650\:m}}}$

25.	Verify Rolle's theorems
Answer» Answer: If f is continuous on [a,b] and differentiable on (a,b), with f(a)=f(b), then there exists C∈(a,b) such that f(c)=0. Step-by-step explanation: The GIVEN function is f(x)=\|9−x2\| on [−3,3]; also find point where the derivative is zero. I got the value of c as ±3, but according to the theorem the value should be in between −3 and 3, i.e., excluding the −3 and 3 The function \|9−x2\| is not differentiable on −3 and 3, so the derivatives cannot be zero at that point, as they do not exist at all. You must have made a mistake somewhere. In your problem particularly, as f(x)=9−x2 we have f′(x)=−2x, as 9−x2≥0 on [−3,3], the point where the derivative is 0 is 0, and only 0. Also, note that Rolle's Theorem SAYS that the point where the derivatives are zero are all in [a,b] where f(a)=f(b). It merely says that there exists such a point. For EXAMPLE, take f(x)=0 on [1,3]. There exists a value where f′(x)=0 on (1,3), but f′(1)=f′(3)=0 as well. So values where f′(x)=0 NEED not always exist in the interval (a,b).

Answer»

Answer:

If f is continuous on [a,b] and differentiable on (a,b), with f(a)=f(b), then there exists C∈(a,b) such that f(c)=0.

Step-by-step explanation:

The GIVEN function is f(x)=|9−x2| on [−3,3]; also find point where the derivative is zero.

I got the value of c as ±3, but according to the theorem the value should be in between −3 and 3, i.e., excluding the −3 and 3

The function |9−x2| is not differentiable on −3 and 3, so the derivatives cannot be zero at that point, as they do not exist at all. You must have made a mistake somewhere.

In your problem particularly, as f(x)=9−x2 we have f′(x)=−2x, as 9−x2≥0 on [−3,3], the point where the derivative is 0 is 0, and only 0.

For EXAMPLE, take f(x)=0 on [1,3]. There exists a value where f′(x)=0 on (1,3), but f′(1)=f′(3)=0 as well. So values where f′(x)=0 NEED not always exist in the interval (a,b).

Answer» Step-by-step explanation: HEYA USER HERE'S YOUR ANSWER ■ CGST is collected by Central GOVERNMENT whereas SGST is collected by State government ■ Apart from that , there is no DIFFERENCE in performing their calculations. ■ Suppose a tax was sold at GST% =x% so, SGST will be calculated as x/2% Similarly CGST will also be calculated as x/2% And then, both are added ALONG with the Marked price to get the Selling price ■ So, we CONCLUDE that they have the same value .

Here's A Question!!.........Does CGST differ from SGST? Is the tax calculated separately? How?.........No Spams!!

Answer»

Step-by-step explanation:

HEYA USER

HERE'S YOUR ANSWER

■ CGST is collected by Central GOVERNMENT whereas SGST is collected by State government

■ Apart from that , there is no DIFFERENCE in performing their calculations.

■ Suppose a tax was sold at GST% =x%

so, SGST will be calculated as x/2%

Similarly CGST will also be calculated as x/2%

And then, both are added ALONG with the Marked price to get the Selling price

■ So, we CONCLUDE that they have the same value .

In triangle LMN, LM = 8cm, MN = 6cm and LMN = 90°X and Y are the midpoints of MN and LN respectively.Find YXN and YN.

Answer»

$\textbf{Converse of Basic proportionality theorem:}$

$\text{If a line divides two sides of a <klux>TRIANGLE</klux> in the same ratio,}$

$\text{then the line is parallel to the third side}$

$\textbf{Given:}$

$\text{In $\triangle$LMN, LM=8cm, MN=6 cm $\<klux>ANGLE</klux>{LMN}=90^{\circ}$}$

$\textbf{To <klux>FIND</klux>:}$

$\angle{YXN}\;\text{and}\;YN$

$\text{In right angled $\triangle$LMN, by pythagoras theorem}$

$LN^2=LM^2+MN^2$

$LN^2=8^2+6^2$

$LN^2=64+36$

$LN^2=100$

$LN=10\;\text{cm}$

$\text{Since X and Y are midpoints of MN and LN,}$

$MX=XN=3\;\text{cm}\;\text{and}\;NY=LY=5\;\text{cm}$

$\implies\dfrac{NX}{MX}=1\;\text{and}\;\dfrac{NY}{LY}=1$

$\implies\bf\dfrac{NX}{MX}=\dfrac{NY}{LY}$

$\text{By converse of basic proportionality theorem, }$

$\text{XY is parallel to ML}$

$\implies\bf\angle{YXN}=90^{\circ}$ $\text{($\because$ corresponding angles are equal})$

$\therefore\textbf{YN=5 cm and $\bf\angle{YXN}=90^{\circ}$}$
