Answer:
The actual square footage of the bedroom is 36 square feet.
Step-by-step explanation:
If one inch from the blueprint is three feet of the actual room, then just multiply twelve by three and you get thirty-six as your answer.
Hope this helped.
Answer:
Hence, option: B is correct (11.02 seconds)
Step-by-step explanation:
Spencer hits a tennis ball past his opponent. The height of the tennis ball, in feet, is modeled by the equation h(t) = –0.075t2 + 0.6t + 2.5, where t is the time since the tennis ball was hit, measured in seconds.
Now we are asked:
How long does it take for the ball to reach the ground?
i.e. we have to find the value of t such that height is zero i.e. h(t)=0.
or 
i.e. we need to find the roots of the above quadratic equation.
on solving the equation we get two roots as:
t≈ -3.02377 and t≈11.0238
As time can't be negative; hence we will consider the value of t as t≈11.0238.
Hence it takes 11.02 seconds for the ball to reach the ground.
Hence option B is correct (11.02 seconds).
The lowest possible product would be -5625 given the numbers 75 and -75.
We can find this by setting the first number as x + 150, which we see in the equation given above. The other number would have to be simply x since it has to have a 150 difference.
Next we'll multiply the numbers together.
x(x+150)
x^2 + 150x
Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2
-b/2a = -150/2(1) = -150/2 = -75
So we know one of the values is -75. We can plug that into the equation to find the second.
x + 150
-75 + 150
75
Answer:
9
Step-by-step explanation: 36 divided by 4 is 9.
For an arithmetic sequence, the nth term is the first term plus (n-1)×the differece
the first term is 28, the difference between each adjacent number is 8
so -36=(28)+8(n-1)
8(n-1)=64
n-1=8
n=9
the 9th term is -36
