Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula. a1
= 0.8, r= −5
Answer:
nth term = 0.8 * -5^(n - 1)
First five terms are: 0.8, -4,
20, -100, 500
Step-by-step explanation:
First term, a1 = 0.8
Common ratio, r = -5
a1 = 0.8
Second term = ar
= 0.8 * -5
= -4
Third term = ar²
= 0.8 * -5²
= 0.8 * 25
= 20
Fourth term = ar³
= 0.8 * -5³
= 0.8 * -125
= -100
Fifth term = ar⁴
= 0.8 * -5⁴
= 0.8 * 625
= 500
First five terms are: 0.8, -4,
20, -100, 500
nth term = ar^(n - 1)
= 0.8 * -5^(n - 1)
nth term = 0.8 * -5^(n - 1)
Drake buys a ring that costs $8,000, which depreciates at a rate of 9.5% per year.
What is the value of Drake's ring after 7 years? Round to the nearest cent.
Answer:
$1129.93
Step-by-step explanation:
100 - 9.5 = 90.5
8000 - 90.5 = 7909.5
7909.5 ÷ 7 = 1129.93

In the diagram below, AC intersects ABDE at B. Choose True or False for each statement
Answer:
false, true . false
Step-by-step explanation:
if u want an explanantion you can ask me :)
Answer: a. True b. True c. False
Explanation:
a. 65+25 =90 complementary angles add up to 90°
b. 65 + b + 25 = 180
90 + b = 180
b = 180 - 90
b = 90
Check-
65 + 25 + 90 = 180
90 + 90 = 180
180 = 180 ✅
c.not vertical angles because they aren’t across from eachother

Please help me I’ll give you 100 points
Answer and Step-by-step explanation:
So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.
Now, the semicircles. They together form a circle.
So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852
Now we add them together.
99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)
The rectangle area is 3180.
The Semi circles' combined area is 99.85.
The total area of the figure is 3279.85.
I hope this helps! Have a great day!
#teamtrees #PAW (Plant And Water)
Answer:
3973.82Step-by-step explanation:
to understand thisyou need to know about:geometryPEMDASlet's solve:there are a rectangle and a full circleaccording to the question
the area of full shape
=[tex]\text{area of the rectangle+the area of the full circle}[/tex]
=(100×31.8)+(π×(31.8/2)²)
=3180+(3.14×(15.9)²
=3180+(3.14×252.81)
=3180+793.8234
=3973.8234
=3973.82

The cost of a 9 litter of petrol is $ 378. How much is 15 litres of petrol cost ?
Answer:
$630
Step-by-step explanation:
cost of each litter of petrol 378/9=42
cost of 15 liters of petrol 42x15=630
15 litters of petrol cost $630
Answer: $630
Step-by-step explanation:
[tex]9l[/tex] = $[tex]378[/tex]
[tex]\frac{378}{9}[/tex] to find [tex]xl[/tex] = $42
This means [tex]1l[/tex] = $42[tex]42[/tex] × [tex]15[/tex] = $[tex]630[/tex]what is the value of x ?
Answer:
97 degrees
Step-by-step explanation:
360 degrees is our total. so:
306 - 60 - 30 - 72 - 46 - 55 = x
x = 97
What value of x will make the equation below true?
х/6=15
Answer:
x+90

Step-by-step explanation:
Ten subjects are being studied to test the effectiveness of itch relief for three types of medication: A, B, and C. Using a 10-point scale, the researcher calculates the subjects' amount of itching
before treatment compared with the amount of itching after treatment. The response variable is the itch rating after one hour of treatment. Previous studies have shown the effects of
treatment may vary based on a subject's pain resistance. How should the subjects be blocked? Explain. (4 points)
They should be blocked alphabetically so the subjects are as different as possible.
They should be blocked by age because older subjects tend to itch more.
They should be blocked by gender because female subjects tend to itch more.
They should be blocked by pain resistance so the subjects are as similar as possible.
O Blocking should not be used in this experiment.
Answer: Choice D
They should be blocked by pain resistance so the subjects are as similar as possible.
============================================================
Explanation:
The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.
Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.
This is why choice D is the final answer.
-------------
Extra info:
Choice A is false because a person's name doesn't have anything to do with if the treatment works or not.Choice B is false because we weren't given any info to indicate it being true. It may be true, but we simply don't have enough info to confirm it. Choice C is false for similar reasons as choice B.Answer:D
Step-by-step explanation:
This is due to the question explicitly stating how the previous studies have shown the effects of treatment may vary based on a subjects pain resistance. This leads to the only option that relates to the study's background, D

Find the equation of the circle that has center (-4,3) and passes through 3,-3
Answer:
(x+4)^2+(y-3)^2 = 85
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the center
r iis the radius
Get the radius
Radius is the distance between the two points
r^2 = (-3-3)^2 + (3-(-4))^2
r^2 - (-6)^2+(7)^2
r^2 = 36+49
r^2 = 85
Substitute (-4, 3) and r^2 = 85 into the formula
(x-(-4))^2 + (y-3)^2 = 85
(x+4)^2+(y-3)^2 = 85
This gives the required equation

• The corresponding angle measures are ________
Answer:
two lines are crossed by another line (called the Transversal): The angles in matching corners are called Corresponding Angles. In this example, these are corresponding angles:
Step-by-step explanation:
In △ A B C , the measure of angle A is 103 ° and the measure of angle B is 37 ° . What is the measure of angle C ?
Step-by-step explanation:
103° + 37° + < C = 180° { being sum of angles of triangle }
< C = 180° - 140°
< C = 40°
