Darya [45]

Answer:

w = 9 \text{ inches}\\l = 13\text{ inches}\\h = 3\text{ inches}      

Step-by-step explanation:

We are given the following in the question:

Volume of cake = 351 cubic inches

Let x inches be the width of cake.

Width of cake, w =

x\text{ inches}

Then, length of cake,l =

(x + 4)\text{ inches}

Height of cake,h =

\dfrac{x}{3}\text{ inches}

Volume of cake = Volume of cuboid

V = lwh

Putting values, we get:

351 = x(x+4)(\dfrac{x}{3})\\\\1053 = x^3 + 4x\\x^3+4x^2-1053= 0\\\\\text{For x = 9}\\(9)^3+4(9)^2-1053= 0

Thus, dimensions of cake are:

w = 9 \text{ inches}\\l = 13\text{ inches}\\h = 3\text{ inches}

A toy rocket was shot into the air. The graph below represents the height over the time of the rocket. Which of the following ar
Ludmilka [50]

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we have given that

A  rocket was fired into the air.

The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.

And it took the rocket 3.5 seconds to reach its maximum height.

and the rocket landed after 6.9 seconds, So option 'D' is false which states  The rocket landed after 34 seconds.

The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.

Hence, Option 'B' and 'C' are correct.
