Answer:
-2.
Step-by-step explanation:
m1 = -1/m if the 2 gradients are perpendicular,
So that would be -1 / (1/2)
= -2.
Answer:
-4
Step-by-step explanation:
10-9=1-5=-4
Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
Answer:
5.1 < x < 16.4
Step-by-step explanation:
If we are given 2 sides of a triangle and need to know the third side (the range of values), we can say that the third side will fall between the DIFFERENCE and SUM of the other 2 sides.
If the third side is c, and other two sides are a and b (where a < b), then the third side would be:
b - a < c < a + b
Thus, here we have third side as "x" and other 2 sides as 5.65 and 10.75, so x would be:
10.75 - 5.65 < x < 10.75 + 5.65
5.1 < x < 16.4
That's the first answer choice: 5.1 < x < 16.4
Answer: hello your question was poorly written but i was able to the get missing parts online which enabled me resolve your question
answer:
a) a = 0.1096
b) 1.89 watts
Step-by-step explanation:
Std of output voltage = 0.25 volt
H0 : μ = 5 volts
Ha : μ ≠ 5 volts
n = 16
a) Acceptance region = 4.9 ≤ X ≤ 5.1
Determine the value of a
value of a = 0.0548 + 0.0548
= 0.1096
<em>attached below is the reaming solution</em>
note : a is a type 1 error
b) power of test
True mean output voltage = 5.1 volts
P = - 1.89 watts
power cant be negative hence the power of the test = 1.89 watts
