In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.
<h3>What is the angle about?</h3>
Note that:
Δ ABC , A = 90
To find length of DA :
Let Δ ACB = x
So Δ ABC = 90 -x
For Δ ABC and ADC:
Δ ADB = Δ ADC (90°)
Δ ABD = Δ DAC (90 - x)
For Δ ABC ≈ ADC:

AD² = BD. CD.
AD²= 9 . 4
AD²= 36
AD = 6
Therefore, In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.

Answer:
see explanation
Step-by-step explanation:
f(x) = - (x + 1)(x - 3)(x + 2)
to find the zeros let f(x) = 0 , that is
- (x + 1)(x - 3)(x + 2) = 0
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 3 = 0 ⇒ x = 3
x + 2 = 0 ⇒ x = - 2
the zeros are x = -1, 3 and x = - 2
to find the y- intercept let x = 0
f(0) = - (0 + 1)(0 - 3)(0 + 2) = - (1)(- 3)(2) = - (- 6) = 6
y- intercept is located at (0, 6 )
Answer:
x - 4 means that the answer will be greater than 3 so the answer could probably, don't take me up on it but it, should be 4 but that is just what my questions answer was. Hope it helps!!!
Answer:
-4.5
Step-by-step explanation:
subtract the numbers on a number line, or subtract normally and make it negative
Answer:
The y-intercept for this equation makes no sense for this model.
Step-by-step explanation:
In this case, the explanatory variable x is the year when the observations were taken. So, the values are the integer numbers between (and including) 1975 and 1986.
The<em> y-intercept for the equation of the linear regression makes no sense for this prediction</em>, for it would correspond to the value x=0 (the year 0) is not consider in the range of the explanatory data.
