Answer:
no
Step-by-step explanation:
this is because it does not follow the pythogras theorem which states that a^2+b^2=c^2
No it is not a right angle
Answer:
answer for this question is -16
Calculate f(x) for all numbers between 0 and 10:
f(0) = −0^2 + 11(0) − 18 = -18
f(1) = −1^2 + 11(1) − 18 = -8
f(2) = −2^2 + 11(2) − 18 = 0
f(3) = −3^2 + 11(3) − 18 = 6
f(4) = −4^2 + 11(4) − 18 = 10
f(5) = −5^2 + 11(5) − 18 = 12
f(6) = −6^2 + 11(6) − 18 = 12
f(7) = −7^2 + 11(7) − 18 = 10
f(8) = −8^2 + 11(8) − 18 = 6
f(9) = −9^2 + 11(9) − 18 = 0
f(10) = −10^2 + 11(10) − 18 = -8
When the value is negative it doesn't drip, so it starts and stops dripping when the values = 0
Which is f(2) and f(9), the values are 2 and 9.
Step-by-step explanation:
y is easy.
it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.
so, Pythagoras :
y² = 8² + 6² = 64 + 36 = 100
y = 10
x is a bit more complex.
I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.
so, if we call the segments of the Hypotenuse a and b with a = 6, we have
x = a + b = 6 + b
height (8) = sqrt(a×b) = sqrt(6b)
therefore,
6b = height² = 8² = 64
b = 64/6 = 32/3 = 10 2/3 = 10.66666666...
so,
x = 6 + 10.66666... = 16.666666666...
round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67
