Step-by-step explanation: Just google it
Pythagorean theorem you times 40 by 2 then 9 by 2 then square root
Answer:
Step-by-step explanation:
we are given a graph
we can see that graph is of parabola
so, the function will be quadratic in nature
Firstly, we can identify zeros
zeros are x=2 and x=4
now, we can set up function
now, we can select anyone point and find 'a'
at x=3 , y=-3
we can use it and find 'a'
now, we can plug it back
and we get
we can multiply it
and we get
Answer:
x = 16
Explanations:
Since △ACD ~ △ABE, it means that:
CD/AD = BE/AE..........(*)
CD = 3x + 8
AD = AE + ED
AD = (x - 1) + 27
AD = x + 26
BE = 20
AE = x - 1
Substituting CD, AD, BE, and AE into equation (*)
(3x+8)/(x+26) = 20/x-1
Cross multiply:
(3x+8)(x-1) = 20(x+26)
3x² - 3x + 8x - 8= 20x + 520
3x²- 15x - 528 = 0
Divide through by 3
x² - 5x - 176 = 0
Solving the quadratic equation above for the values of x
x² - 16x + 11x - 176 = 0
x(x - 16) + 11 (x - 16) = 0
(x - 16)(x + 11) = 0
If x - 16 = 0
x = 16
If x + 11 = 0
x = -11
x cannot be -11 because x = -11 will make side CD and AE to be negative, and the sides of a triangle cannot be negative.
Therefore, x = 16
