Someone please help i just need help with this one question please and thank you :)

Thanks for asking!

Step-by-step explanation:

For ABD x equals 18 and for DBC equals 54.

ABD = 36

DBC = 54

Step-by-step explanation:

The three angles form a straight line so they add to 180

2x + 3x +90 = 180

Combine like terms

5x+90 =180

Subtract 90 from each side

5x+90-90=180-90

5x= 90

divide each side by 5

5x/5 = 90/5

x =18

ABD = 2x = 2*18 = 36

DBC = 3x = 3*18 =54

make sure you have version 2.50

try looking in the very back of the book : )

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
