12 cm³ or 12 mL

Step-by-step explanation:

To find the volume of object A, we’ll use the formulae; L * W * H;

Where L = Length

W = Width

H = Height

Since all values are given, well just multiply them;

4 * 3 * 1 = 12 cm³

1 cubic centimeter is equivalent to 1 mL so we can also write the answer as 12 mL

Find the values of the variables in the parallelogram. The diagram is not to scale.
Anna [14]

Answer:

  • Option C

Step-by-step explanation:

  • x = 36° as alternate interior angles are congruent
  • z = 110° as opposite angles of parallelogram are congruent
  • x + y + 110° = 180° as adjacent angles of parallelogram are supplementary
  • y = 180° - 110° - 36° =  34°

Correct choice is C

A rock is thrown upward from a bridge that is 57 feet above a road. The rock reaches its maximum height above the road 0.76 seco
bekas [8.4K]

answer:

f(t) = -9.9788169(t -0.76)^2 +57

Step-by-step explanation:

On this question we see that we are given two points on a certain graph that has a maximum point at 57 feet and in 0.76 seconds after it is thrown, we know can say this point is a turning point of a graph of the rock that is thrown as we are told that the function f determines the rocks height above the road (in feet) in terms of the  number of seconds t since the rock was thrown therefore this turning point coordinate can be written as (0.76, 57) as we are told the height represents y and x is represented by time in seconds. We are further given another point on the graph where the height is now 0 feet on the road then at this point its after 3.15 seconds in which the rock is thrown in therefore this coordinate is (3.15,0).

now we know if a rock is thrown it moves in a shape of a parabola which we see this equation is quadratic. Now we will use the turning point equation for a quadratic equation to get a equation for the height which the format is f(x)= a(x-p)^2 +q  , where (p,q) is the turning point. now we substitute the turning point

f(t) = a(t-0.76)^2 + 57, now we will substitute the other point on the graph or on the function that we found which is (3.15, 0) then solve for a.

0 = a(3.15 - 0.76)^2 + 57

-57 =a(2.39)^2  

-57 = a(5.7121)

-57/5.7121 =a

-9.9788169 = a      then we substitute a to get the quadratic equation therefore f is

f(t) = -9.9788169(t-0.76)^2 +57
