Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm

Area of the top = area of the base = 64.5cm

Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm

Total surface area = 64.5 + 64. 5+ 330 = 459 cm²

------------------------------------------------------------------------
Answer: Total surface area = 459 cm²

Please help!(30pts)(I NEED IT QUICK)Find the inverse of the given function:
bezimeni [28]

y = -(1/2) sqrt(x + 3) Interchange the x and y

x = -(1/2) sqrt(y + 3) multiply through by - 2

-2x = sqrt(y + 3) Square both sides.

(-2x)^2 = (sqrt(y + 3))^2

4x^2 = y + 3 Subtract 3 from both sides.

y = 4x^2 - 3

The usual rule is to interchange the domain and range of the original equation with the inverse. The range of the original equation is 0 => y > -infinity.

If that is the case, then the domain of the inverse is 0<=x. The graph was revised and provided by Mathmate. It is the correct way to represent this function and it's inverse Including the fact that x<=0. That restriction is very important. The line is x = y and the graphs should reflect around that line.

Two number cubes are rolled.
hichkok12 [17]

Answer:

When two number cubes  are rolled,

Sample space= Total Possible outcome {11,22,33,44,55,66,12,21,13,31,14,41,15,51,16,61,23,32,24,42,25,52,26,62,34,43,35,53,36,63,45,54,46,64,56,65}=36

Probability of an event = \frac{\text{Total favorable outcome}}{\text{Total possible outcome}}

Sum of 4 is obtained when ={13,31,22}=3

Probability of getting 4 when 2 number cubes are rolled= \frac{3}{36}=\frac{1}{12}

Sum of the numbers is greater than 9= 10, 11,12={55,64,46,56,65,66}=6

Probability of getting(Sum of the numbers is greater than 9)=\frac{6}{36}=\frac{1}{6}
