The answer would be d 1 1/18 because you have to convert the 1/6 to 3/18 and 2/9 to 4/18 so 4/18 minus 3/18 is 1/18 and 8 minus 7 is 1 so it is 1 1/18

First of all, you will want to change the fraction to have the same denominator.

The common factor for 9 and 6 is 18. (9x2=18 and 6x3=18)
Then, you multiply the numerator by the factor you got in the first step, which is 2 and 3, respectively.
So the new fractions are $\frac{4}{18}$ and 7 $\frac{3}{18}$

The next step is to simply subtract the mixed numbers!
$8 \frac{4}{18}$ - $\frac{3}{18}$ = 1 1/18

The answer would be <span>D: 1 1/18!</span>

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = ln x, [1,7] choose one letter t

inn [45]

ANSWER

B.Yes, f is continuous on [1, 7] and differentiable on (1, 7).

$c\approx 3.08$

EXPLANATION

The given

$f(x) = ln(x)$

The hypotheses are

1. The function is continuous on [1, 7].

2. The function is differentiable on (1, 7).

3. There is a c, such that:

$f'(c) = \frac{f(7) - f(1)}{7 - 1}$

$f'(x) = \frac{1}{x}$

This implies that;

$\frac{1}{c} = \frac{ ln(7) - 0}{6}$

$\frac{1}{c} = \frac{ ln(7)}{6}$

$c = \frac{6}{ ln(7) }$

$c\approx 3.08$

Since the function is continuous on [1, 7] and differentiable on (1, 7) it satisfies the mean value theorem.

The altitude of a triangle is increasing at a rate of 1 cm/min while the area of the triangle is increasing at a rate of 2 cm^2/

VARVARA [1.3K]

Answer:

The base is decreasing at 2 cm/min.

Step-by-step explanation:

The area (A) of a triangle is given by:

$A = \frac{1}{2}bh$ (1)

Where:

b: is the base

h: is the altitude = 10 cm

If we take the derivative of equation (1) as a function of time we have:

$\frac{dA}{dt} = \frac{1}{2}(\frac{db}{dt}h + \frac{dh}{dt}b)$

We can find the base by solving equation (1) for b:

$b = \frac{2A}{h} = \frac{2*120 cm^{2}}{10 cm} = 24 cm$

Now, having that dh/dt = 1 cm/min, dA/dt = 2 cm²/min we can find db/dt:

$2 cm^{2}/min = \frac{1}{2}(\frac{db}{dt}*10 cm + 1 cm/min*24 cm)$

$\frac{db}{dt} = \frac{2*2 cm^{2}/min - 1 cm/min*24 cm}{10 cm} = -2 cm/min$

Therefore, the base is decreasing at 2 cm/min.

I hope it helps you!

10 times as many as _ hundreds is 60 hundreds or _ thousands

vovangra [49]

60 hundreds = 60 * 100 = 6,000 ( six thousands )
10 * 600 = 6,000 ( 10 times as many as 600 is 6,000 - six thousands )
Answer:
10 times as many as 6 hundreds is 60 hundreds or 6 thousands.

What is a reflexive angle?

zalisa [80]

Is the larger angle. It is more than 180° but less than 360° If you choose the smaller angle you might have an Acute Angle, or an Obtuse Angle instead: The larger angle is a Reflex Angle, but the smaller angle is an Acute Angle.
