Answer:
the answer is 17 since you multiply a negative 5 by a negative which is positive 10 and add 7 to that its 17
Step-by-step explanation:
Answer:
So just multiply the (4,6) and (5,4) then divide it by 3
Step-by-step explanation:
Answer:
48 cm
Step-by-step explanation:
Given:
Distance of rod from the wall = 45 cm
Distance of rod from the light = 15 cm
Length of rod = 12 cm
We can see that <DAM and <BAF are equal
Also, <DMA and <BFM are equal because they are corresponding angles
To find the length of the shadow, let's take the equation
Where.:
DM = ½ of length of the rod = ½*12 = 6
A.F = 15 + 45 = 60 cm
AM = 15 cm
Therefore,
Cross multiplying, we have:
15 * B.F = 60 * 6
15 * B.F = 360
BF = 24 cm
The shadow on the wall =
2 * BF
= 2 * 24
= 48 cm
The shadow on the wall is 48 cm
The domain of this function is going to be all of the real POSITIVE numbers EXCEPT when the denominator equals 0, because you can't divide by 0, therefore:
(√x) - 2 = 0
(√x) = 2
x = 2^2
x = 4
Therefore, the domain is all of POSITIVE real numbers EXCEPT 4
