Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,
![\frac{BC}{AC}=\frac{CD}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BAC%7D%3D%5Cfrac%7BCD%7D%7BBC%7D)
![\frac{y}{(4+6)}=\frac{6}{y}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7B%284%2B6%29%7D%3D%5Cfrac%7B6%7D%7By%7D)
y² = 60
y = √60
y = 7.75
Similarly, ![\frac{AB}{AC}=\frac{AD}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAC%7D%3D%5Cfrac%7BAD%7D%7BAB%7D)
![\frac{x}{(4+6)}=\frac{4}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B%284%2B6%29%7D%3D%5Cfrac%7B4%7D%7Bx%7D)
x² = 40
x = √40
x = 6.32
Answer:
Real (z) = 12.1
Im (z) = 14
Step-by-step explanation:
z = 14i and 12.1
This is in the form bi +a
We normally write it a +bi
z =12.1 + 14i
The real part is a and the imaginary part is b
Real (z) = 12.1
Im (z) = 14
Answer:
D
Step-by-step explanation:
Answer:
(B)
Step-by-step explanation:
v^2 = v0^2 + 2ax
a = (v^2 - v0^2) / 2x
= (20^2 - 10^2) / 200
= 1.5 m/s
If you would like to know which of the above is a factor of f(x) = 7 * x^3 − 22 * x^2 − 67 * x + 10, you can find this using the following steps:
f(x) = 7 * x^3 − 22 * x^2 − 67 * x + 10
f(x) = (x + 2) * (7x^2 - 36x + 5)
f(x) = (x + 2) * (x - 5) * (7x - 1)
The correct result would be (x - 5).
