Find the 7th term in the sequence -1,2,-4,8
Answers
=======================================
Work Shown:
We have a geometric sequence
a = first term = -1
r = common ratio = (second term)/(first term) = 2/(-1) = -2
nth term
a(n) = a*(r)^(n-1)
a(n) = -1*(-2)^(n-1)
Now plug in n = 7 to get the 7th term
a(n) = -1*(-2)^(n-1)
a(7) = -1*(-2)^(7-1)
a(7) = -1*(-2)^6
a(7) = -1*(64)
a(7) = -64
The first seven terms are
-1, 2, -4, 8, -16, 32, -64
To get each new term, we multiply the last term by the common ratio -2
There’s not really an exact way to do this, you just have to look for a pattern.
This sequence follows the following notation:
An= -(-2^(n-1))
Then, we can plug 7 in for n.
A7 = -(-2^(n-1))
A7=-(-2^6)
A7=-64

number one is SAS
1. B. ΔJKE ≅ ΔLYE because SAS.
2. E. No enough information to prove the triangles are congruent.
What is the SAS Theorem?The SAS theorem is a triangle congruence theorem which states that two triangles which have two pairs of corresponding sides that are congruent and a pair of corresponding included angles that are congruent are congruent triangles.
1. Based on the SAS theorem we can conclude that: B. ΔJKE ≅ ΔLYE because SAS.
2. In the triangles given, we are only given that they have two pairs of corresponding congruent sides. No known congruent sides were given. Therefore, we don't have enough information. The answer is: E. No enough information to prove the triangles are congruent.

a) write an equation of a line parallel that passes through the point (-16, 4).
b) write an equation of a line perpendicular that passes through the point (9, -7).
Answers
Answer:
use slope intercept formula
y=Mx +b
Step-by-step explanation:
3X-4Y=8
3X-8 = 4Y
y = 3/4x-2
our new equation just needs to have the same slope M= 3/4
y-y1=M(x-x1)
y-4=3/4(x-(-16))
y=3/4x+12+4
y=3/4x+16 answer a
for a perpendicular line.. just take the inverse of the slope... and change the sign. so now our slope is - 4/3
plug in our new point (9,-7)
y-(-7) = -4/3(x-9)
y+7=-4/3x+12
y= -4/3x +5 answer b

The probability that the number selected is odd or less than five will be 0.20 or 20%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

equivalent fractions for 2 1/5 and 1 5/6 with common denominator 30
Answers
Answer:
[tex]\frac{66}{30} and \frac{55}{30}[/tex]
Step-by-step explanation:
Firstly, let's get the fractions out of mixed form.
2 1/5 = 11/5
(To do this, multiply 2 times 5 and add to the 1.)
1 5/6 = 11/6
(To do this, multiply 1 times 6 and add to the 5.)
Next, let's get the common denominator. When making a common denominator, keep in mind you must multiply/divide both the numerator and denominator.
[tex]\frac{11}{5} * \frac{6}{6} = \frac{66}{30}[/tex]
and
[tex]\frac{11}{6} * \frac{5}{5} = \frac{55}{30}[/tex]

what is the best estimate of 45 percent of 76

383434.2 (actual value)Step-by-step explanation:
In my engineering experience, a method of estimating should satisfy two requirements:
it should be relatively easy to accomplish mentallyit should provide a means of estimating the error in the estimate__
Multiplication and division by 2 are generally easy to perform mentally.
We note that 45% is about 50%.
50% of 76 is 76/2 = 38 . . . a good starting estimate
45% is down 5% from 50%, so the actual value will be 5/50 = 10% lower than this first estimate
A good second estimate is 38 -0.10(40) = 34.
A better estimate is 38 -3.8 = 34.2, which is the actual value of the expression.
_____
Alternate approach
You could also transform the problem to 76% of 45, which is about 3/4 of 44, or about 33. Figuring the error adjustment on this approach is somewhat more difficult, as it is factors of 1/75 and 1/44 too low. 1 part in 44 is not too difficult to figure, as it is 33/44 = 3/4, so a better estimate is 33.75. It takes a calculator to figure 1 part in 75 of this, which is 0.45. Adding that amount gets you to the actual value of 34.2.
