The diagonal of a square is 4 cm . Find it's area. |
|
Answer» Answer: It is given that diagonal BD= 4 cm(See the enclosed figure) Let each side of the square be 'a'. Here, ∆BAD and ∆BCD are right TRIANGLES (ABCD is a square). Now, applying PYTHAGORAS theorem in ∆ABD, (Hypotenuse)²= (Base)²+(PERPENDICULAR)² (BD)²= (AB)²+(AD)² (4)²= (a)²+(a)²--------(All the sides of a square are EQUAL ) 16= 2a² 16÷2= a² 8= a² 2√2 cm= a Thus, each side of the square is of length 2√2 cm Now, Area of a square= a² where a is the side => (2√2)² => 4×2 => 8 cm² Answer=> 8 cm² |

The points (-2,5) and (3,-5) are plotted in xy planes. Find the slope and y intercept of the line joining the points. |
|
Answer» Step-by-step explanation: As the points given as(-2,5) and (3,-5). Now, slope(m) has the formulae as m=(y2-y1)/(x2-x1).
Now, here x1 and y1 are -2 and 5. And x2 and y2 is 3 and -5. Hence, Slope m=(-5-5)/(3-(-2)) m=-10/5 = -2 Now, putting the VALUE of m in the equation of a straight line y=mx +C y= -2x +c Putting the value of any point in the equation LET (-2,5). 5=-2*-2+c c= 5-4= 1 Hence, y INTERCEPT is 1.
If you would have taken the value of (3,-5) same value of c which is y intercept would have come. |

Find the x-intercept and the y-intercept for 2x+y=8 then use them to graph the line. |
|
Answer» Find the x-intercept by SUBSTITUTING in 0 for y and solving for x. Find the y-intercept by substituting in 0 for x and solving for y. Let's find the x-intercept FIRST: 2x + (0) = 8 2x = 8 Divide both sides by 2 to isolate and solve for the variable "x", or the x-intercept. x = 4 (x-intercept) Now find the y-intercept: 2(0) + y = 8 Multiply 2 and 0. y = 8 (y-intercept) You have found the x-intercept to be 4 and the y-intercept to be 8. To graph the LINE, place a point on (4, 0) ← x-intercept and a point on (0, 8) ← y-intercept. Your line should look like the attached image :) |
