Hello!
The fraction is an improper fraction (the numerator is greater than the denominator). The whole number part of the mixed number is found by dividing the 24 by the 9. The fractional part of the mixed number is found by using the remainder of the division, which in this case is 6 (24 divided by 9 is 2 remainder 6).
Given that the <span>formula for a trapezoid that relates the area A, the two bases, a and b, and the height, h is given by:
To solve for b, first multiply both sides by 2 to get:
2A = h(a + b) = ah + bh
Next, subtract ah from both sides to get:
2A - ah = bh
Next, divide both sides by h, to get:

Answer:
1.2
Step-by-step explanation:
Answer:
1. 20.505N
2.8.876N
3. -13.686N
Step-by-step explanation:
1. xcos75 + xsin75 = 26N
x(cos75+sin75) = 26; x = 26/(cos75+sin75)
x = 26/1.2247 = 21.229
vertical component is 21.229 sin75 = 20.505 N
2. xcos30 + xsin30 = 14N
x(cos30 + sin30) = 14; x = 14/1.366 = 10.249
horizontal component is 10.249 x cos30 = 8.876N
3. net force on the vertical direction.
xcos37 + xsin37 = 24
x(cos37+sin37) = 24; x = 24/(cos37+sin37) = 24/1.400 = 17.137
verical component is 17.137 x sin37 =10.314
we are given that the box excert a force of 22N downwards, so the net vertical component is 10.314 - 24 = -13.686N
Answer:
A function means that we get one input and one output. In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points. Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
