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 5 2/3 - 3 1/5 A. 5 2/3 B. 8 13/15 C. 2 7/15 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?

Answer:

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.

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

y = 11x
