The answers are A and F.
You can tell by looking at the slopes and seeing that they've been flipped and one is positive while the other is negative.

Solution: =====> -7 + {12 - 3[50 - 4(2 + 3) ] } ======> -85

Simplify :

−7 + 12 − 3(50 - 4(2 + 3))

= 5 − 3(50 − 4(2 + 3))

= 5 − 3(50 − (4)(5))

= 5 − 3(50 − 20)

= 5 − (3)(30)

= 5 − 90

= − 85

Answer ========> -85

Hope that helps!!!! : )

In an arithmetic sequence, the nth term an is given by the formula an=a1+(n−1)d, where a1 is the first term and d is the commo

Dmitry_Shevchenko [17]

Answer:

$a_{10} = \frac{10}{65536}$

Step-by-step explanation:

The first step to solving this problem is verifying if this sequence is an arithmetic sequence or a geometric sequence.

This sequence is arithmetic if:

$a_{3} - a_{2} = a_{2} - a_{1}$

We have that:

$a_{3} = 40, a_{2} = 10, a_{3} = \frac{5}{2}$

$a_{3} - a_{2} = a_{2} - a_{1}$

$\frac{5}{2} - 10 = 10 - 40$

$\frac{-15}{2} \neq -30$

This is not an arithmetic sequence.

This sequence is geometric if:

$\frac{a_{3}}{a_{2}} = \frac{a_{2}}{a_{1}}$

$\frac{\frac{5}[2}}{10} = \frac{10}{40}$

$\frac{5}{20} = \frac{1}{4}$

$\frac{1}{4} = \frac{1}{4}$

This is a geometric sequence, in which:

The first term is 40, so $a_{1} = 40$

The common ratio is $\frac{1}{4}$ , so $r = \frac{1}{4}$ .

We have that:

$a_{n} = a_{1}*r^{n-1}$

The 10th term is $a_{10}$ . So:

$a_{10} = a_{1}*r^{9}$

$a_{10} = 40*(\frac{1}{4})^{9}$

$a_{10} = \frac{40}{262144}$

Simplifying by 4, we have:

$a_{10} = \frac{10}{65536}$

cylinder A has a radius of 6 centimeters cylinder B has the same height and a radius half as long as cylinder A what fraction of

REY [17]

Volume of a cylinder=the area of the base multiply the height
Cylinder A's volume: pi*6*6*h=36*pi*h
Cylinder B's volume: pi*3*3*h=9*pi*h
so the fraction is 9/36=1/4
