Step-by-step explanation:

The only way the answer could be E is if the x² term under the radical is supposed to be t².

f(x) = ∫₄²ˣ √(t² − t) dt

f'(x) = √((2x)² − 2x) (2)

f'(x) = 2√(4x² − 2x)

f'(2) = 2√(4(2)² − 2(2))

f'(2) = 2√12

What is the sum of the infinite geometric series? 120 + 20+ 10/3 + 5/9+...

Sergeu [11.5K]

Answer:

for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by

$\frac{a_{1} }{1 - r}$ = $\frac{120}{1 - \frac{1}{6} } = \frac{120}{\frac{5}{6} } =$ $\frac{120 \times 6}{5}$ = 144.

Step-by-step explanation:

i) from the given series we can see that the first term is $a_{1 }$ = 120.

ii) let the common ratio be r.

iii) the second term is 20 = 120 × r

therefore r = 20 ÷ 120 = $\dfrac{1}{6}$

iv) the third term is $\frac{10}{3}$ = 20 × r

therefore r = $\dfrac{10}{3}$ ÷ 20 = $\dfrac{1}{6}$

v) for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by

$\frac{a_{1} }{1 - r}$ = $\frac{120}{1 - \frac{1}{6} } = \frac{120}{\frac{5}{6} } =$ $\frac{120 \times 6}{5}$ = 144.

We roll 3 dice and add the results. what is the probability that the total is NOT 18?

exis [7]

To answer this you need to find the probability that it is 18 first. The only way to get 18 is by rolling 3 6's. The probability of each 6 is 1/6. 1/6 * 1/6 * 1/6= 0.0046. That is the probability of rolling 3 die and getting 18. To get the actual answer, you just subtract that from 1
1-0.0046 equals 0.9954

MATH HELP PLEASE!!! I WILL MARK BRAINLIEST

Zielflug [23.3K]

Answer:

Store 1

Step-by-step explanation:

Because the hammer is new, so the number of items sold would be lower.

Store 1's line of fit shows that the less number of items of a specific type is sold, the greater its value.

So, to get the greatest value, he'll sell in the first store.
