the fifth term of an arithmetic sequence is 23 and the 12th is 72. determine the next three terms and general formula
Answer:
first three terms are -5 , 2, and 9
Step-by-step explanation:
term(n) = a + (n-1)d
term5 = a+ 4d = 23
term12 = a + 11d = 72
subtract them
7d = 49
d = 7
sub into a+4d = 23
a + 28 = 23
a = -5

Answer:
D 9/DF = 18/16
Step-by-step explanation:
Corresponding sides are proportional. The proportions based on a given similarity statement can be written 4 ways.
For these isosceles triangles, the similarity statement could be written either of two ways:
ΔDEF ~ ΔABC or ΔDEF ~ ΔCBA
Corresponding sides will depend on the similarity statement you use. Using the first one, they are ...
DF and AC (short sides)
DE and AB (long sides)
EF and BC (long sides)
For each (short side, long side) pair, we can write the proportion 4 ways:
DF/DE = AC/AB ⇒ DF/9 = 16/18DF/AC = DE/AB ⇒ DF/16 = 9/18DE/DF = AB/AC ⇒ 9/DF = 18/16 . . . . . matches choice DAC/DF = AB/DE ⇒ 16/DF = 18/9Using the other pair of long sides, or using the other similarity statement, the numerical proportions are the same as the ones listed above.

The athletics director at Peter's school has created a phone tree that is used to notify team players in the event a
game has to be canceled or rescheduled. The phone tree is initiated when the director calls two captains. During
the second stage of the phone tree, the captains each call two players. During the third stage of the phone tree,
these players each call two other players. The phone tree continues until all players have been notified. If there are
50 players on the teams, how many stages will it take to notify all of the players?

Answer:
8 boxes
Step-by-step explanation:
Surface area of the rectangular prism:
A=2(wl+hl+hw)
A = 2(5·4+7·4+7·5) = 166
The 166 represents the square ft of one box.
Take the total number of wallpaper she has, 1328 ft^2, and divide by 166 to find the number of boxes that she can cover.
[tex]\frac{1328}{166} = 8[/tex]
Hope that helps!
Answer:
Step-by-step explanation:
Firstly lets calculate the total surface area of the cuboid
Total surface area of cuboid (A1)
= 2( l*b+ b*h +l*h)
= 2( 7 * 5+ 5 * 4 + 7 * 4)
= 166 ft²
also given that
Total area of the wallpaper ( A2)= 1328 ft²
Now
Number of boxes that she can cover is
= A2 / A1
= 1328 / 166
= 8 BOXES.
hope it will help :)

ne positive integer is 4 less than twice another. The sum of their squares is 356. Find the integers
9514 1404 393
Answer:
16 and 10
Step-by-step explanation:
Let x and y represent the two integers.
x = 2y -4 . . . . . one is 4 less than twice another
x^2 +y^2 = 356 . . . . the sum of their squares is 356
We can solve these using substitution.
(2y -4)^2 +y^2 = 356 . . . . substitute for x
5y^2 -16y +16 = 356 . . . . simpify
5y^2 -16y -340 = 0 . . . . . put in standard form
(5y +34)(y -10) = 0 . . . . . . factor*
y = 10 . . . . . the only positive solution
x = 2(10) -4 = 16
The integers are 16 and 10.

there are 4 roses for every 7 carnations in a bouqeuet. Mr rodriguez buys a bouqeuet with 12 roses in it. How many total flowers are in the bouqeuet Mr rodriguez bought?
Please explain
Answer:
Step-by-step explanation:
there is a 4 to 7 ratio in the first situation.
so if there is (4*3) the it would be (7*3) so it would be 21 carnations
this gives 12+21 for a total of 33 flowers.
the ratio is 4/7 so you could also go (4/7)(12) and then add that to the original 12 in the boqouet in order to get the same answer. Hope this helps!
A researcher is investigating the relationship between the length, in centimeters, and weight, in grams, of pineapples. The researcher will select a random sample of 15 pineapples from grocery stores in a region and construct a 95% confidence interval for the slope of the population regression line, where length is the explanatory variable and weight is the response variable. When computing a confidence interval for the slope of the population regression line, which of the following is not a condition that must be checked?
A. The true relationship between length and weight is linear.
B. The standard deviation for weight does not vary with length.
C. The values of weight are approximately normally distributed at each value of length.
D. The sum of the residuals is zero.
E. The observations are independent.
Answer:
D. The sum of the residuals is zero.
Step-by-step explanation:
The relation between length and weight of pineapples is observed. The observation should be independent and the values must be normally distributed in order to find the confidence interval for slope of population regression line.
Since the enactment of a smoking ban in a particular city, the number of smokers has slowly declined. Statistics show that the number of smokers in this city has decreased for four consecutive months by 3%, 2%, 5%, and 2%. What was the overall percentage decrease in the number of smokers during this four month period? Round your answer to the nearest tenth of a percentage point.
Answer:
11.5%
Step-by-step explanation:
Let the number of smokers before ban = 100
Decrease in 1st month = 3% , of 100 = 3
Smokers after 1st month = 100 - 3 = 97
Decrease in 2nd month = 2%, of 97 = 1.94
Smokers after 2nd month = 97 - 1.94 = 95.06
Decrease in 3rd month = 5%, of 95.06 = 4.75
Smokers after 3rd month = 95.06 - 4.75 = 90.31
Decrease in 4th month = 2%, of 90.31 = 1.80
Smokers after 4th month = 90.31 - 1.80 = 88.51
Decrease in smokers after 4th month = (Decrease / old value) x 100[ (100 - 88.51) / 100 ] x 100 = (11.49 / 100) x 100
= 11.5%

Can someone help finds the area of this figure
9514 1404 393
Answer:
49 cm^2
Step-by-step explanation:
The shape is a 3 × 3 square on top of a 4 × 10 rectangle. The area of each rectangle is found by multiplying the dimensions.
Total Area = (3 cm)(3 cm) +(4 cm)(10 cm) = 9 cm^2 +40 cm^2
Total area = 49 cm^2

DetermIne the inverse function of f(x) = 1/3 + 6
Please show work
Answer:
f(x)⁻¹ = 3x - 18
Step-by-step explanation:
I'm going to assume that 1/3 is the coefficient of the x.
f(x) = 1/3x + 6
y = 1/3x + 6
x = 1/3y + 6
x - 6 = 1/3y
3x - 18 = y
f(x)⁻¹ = 3x - 18
The Graph of a function g is shown below. Find the following: g(10)
Answer: the graph is not shown, but I'll try to explain how hypothetically, you would be able to graph g(10). If you are given something like an image of the graph, find slope and y-intercept first. The y-intercept is the point (0, #), and is on the y-axis. After finding what g(x) = mx + b <- slope intercept form is, substitute 10 for x, then solve.
