A.Yes a function as a vertical line crosses the curve at one point only.
B.the domain is [-4,3]
C. the range is [-3,3]
D. it's -3
The absolute value of x is 4
Assuming you meant
Then you can compose the function g(x)
With the function
Because f (g(x) ) means that you first find (calculte)
and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
The picture shown is a unfolded rectangular prism.
The formula to find the surface area of a rectangular prism is:
A = 2(WL+HL+HW)
(W = width, L = Length, H= Height)
So we would need to determine the Height, Length, and Width first, and then plug them into the formula and solve for the area.
In this case:
The height is: 4 cm
The length is: 10.5 cm
The width is: 6.4 cm
Now that we have determined the height, length, and width, we simply plug them into the formula I showed earlier.
In this case the answer would be 269.6.
D. 269.6
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
