Question

Find the missing values

hintHint:

Find the value of x and z by using the sum of  angles of the triangle is 180°. Then find y by using the sum of angles on a straight line is 180°.

The correct answer is: x = 62 ; y = 59 ;z = 59


    ANS :-  x = 62 ; y = 59 ;z = 59
    Explanation :-
    Step 1:- Find x
    28°+ 90°+ x°=180°(sum of angles in a triangle)
    x°+ 118° = 180°
    x° = 180 - 118°  x° = 62°
    ∴ x = 62
    Step 2:- Find Z
    31°+ 90°+ z°=180°(sum of angles in a triangle)
    z°+ 121° = 180°
    z° = 180 - 121°  z° = 59°
    ∴ z = 59
    Step 3:- Find y
    x°+ y°+ z° = 180° (sum of angles on a straight line)
    Substitute values of x and z
    y° + (62+59)° = 180°
    y° = 180 - 121°  y° = 59°
    ∴ y = 59

    The table above shows selected values for the function h . In the x y -plane, the graph of y = h(x) h  is a line. What is the value of (8)  ?

    Note:
    After finding the equation y = 2x + 3 , we can verify it by putting the third point in the equation and check if it lies on the line, that is, the third point which is  left parenthesis 4 comma 11 right parenthesis lies on y equals h left parenthesis x right parenthesis
    11 equals 2.4 plus 3
    So, the equation  h left parenthesis x right parenthesis equals 2 x plus 3 is the graph of y equals h left parenthesis x right parenthesis.

    The gas mileage M (s), in miles per gallon, of a car traveling s miles per hour is modeled by the function below, where  20 less or equal than s less or equal than 75.
    M left parenthesis s right parenthesis equals negative 1 over 24 s squared plus 4 s minus 50
    According to the model, at what speed, in miles per hour, does the car obtain its greatest gas mileage?

    Note:
    We could have also used the first derivative test to find the local
    maxima. We need to find critical points and then check whether the
    function is increasing or decreasing on either side of the critical
    point. If the function is increasing , i. e M to the power of straight prime left parenthesis S right parenthesis greater than 0.,  on the left side
    and the function is decreasing, i. e M to the power of straight prime left parenthesis s right parenthesis less than 0.,  on the right hand side, then we say that  is a local maxima.
