Answer:

The lowest point is -100 meters, or 100 meters down

Step-by-step explanation:

D(x)=1/36(x-60)^2-100

This equation is in vertex form

y = a(x-h)^2 +k  where (h,k) is the vertex

Since a is positive, the parabola opens up

The vertex is the minimum, which means it will be the lowest point

The vertex is (60,-100)

The lowest point is -100 meters, or 100 meters down

Find the difference <br> 5 2/3 - 3 1/5 <br> A. 5 2/3<br> B. 8 13/15<br> C. 2 7/15<br> D. 3 1/5
RSB [31]

To find the difference of given expression:

5\frac{2}{3} -3\frac{1}{5}

First step is to subtract the whole number5 and 3.

So, 5 - 3 = 2.

Now we can find the difference of fractions.

To subtract the fractions , we need to find the common denominator.

Common denominator of 3 and 5 is 15.

So, we need to make both the denominator equal to 15.

\frac{2}{3} =\frac{2*5}{3*5} =\frac{10}{15}

Similarly, \frac{1}{5} =\frac{1*3}{3*5} = \frac{3}{15}

Therefore, \frac{2}{3} -\frac{1}{5} =\frac{10}{15} -\frac{3}{15}

=\frac{10-3}{15}

= \frac{7}{15}

So, the difference of given expression is 2\frac{7}{15}.

So, the correct choice is C.

What is the value of this expression?
mylen [45]

9514 1404 393

Answer:

  2

Step-by-step explanation:

I find it convenient to remember that a logarithm is an exponent.

  \log_a(a^b)=b

__

  log₂(8) +log₃(1/3) = log₂(2³) +log₃(3⁻¹)

  = 3 -1 = 2

The value of the expression is 2.

__

Some calculators can compute this for you directly.

8) The height of a stack of CD cases is Proportional to the number of CD’s in the stack. A stack of 6 CD’s is 66mm high.* Find t
motikmotik

Step-by-step explanation:

well, when 6 CD cases are 66 mm high, then 1 CD case is 66/6 = 11 mm high.

a)

therefore, 10 CD cases are 11×10 = 110 mm high.

b)

y = 11x
