Find the sum of the following arithmetic sequence. 4,10,16,22,28
Answer:
Step-by-step explanation:
This is the formula to find the sum of the first
n
terms of the sequence. To evaluate it, the values of the first and
n
the terms must be found .Sn=n2⋅(a1+an)
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
6
to the previous term in the sequence gives the next term. In other words,
an=a1+d(n−1)x Arithmetic Sequence:
d=6 This is the formula of an arithmetic sequence X an=a1+d(n−1)Substitute in the values of a1=4 and d=6 x an=4+(6)(n−1)Simplify each term.
an=4+6n−6 Subtract 6 from 4 x an=6n−2 Substitute in the value of N to find the N the term x a5=6(5)−2 Multiply 6 by 5 x a5=30−2 Subtract 2 from 30 x a5=28 Replace the variables with the known values to find
S5 x S5=52⋅(4+28)Add 4 and 28 x S5=52⋅32
Cancel the common factor of

Which of the following fractions is equivalent to 1.68? A. 25/42 B. 17/25 C. 42/25 D. 7/4
Answer:
42/25 or C
Step-by-step explanation:
Just by looking at the answers, we can eliminate A and B because the equivalent decimals of those would result in a number that is less than one.
Then, you can eliminate D because 7/4 is equal to 1.75
Therefore, your answer would be C, 42/25.
The first number in a pattern is 156. The pattern follows the rule subtract 19. What are the next three numbers?
1 137, 118, 99
2 118, 99, 80
3 137, 119, 100
4 137, 118, 98
Answer:
A
The answer would be A because what is 156- 19=137 so we now take out number 2/B
137-19=118 So that means we can eliminate number 3/c that says 119 so that's out now.
And for last number the 3rd number to subtract is what is 118-19=99 so we just eliminated number 4 that says 98.
And the only number that followed our answers and ad the same answer for us was A so lets go with A.

A phone company offers two monthly plans. Plan A costs $15 plus an additional $0.14 for each minute of calls. Plan B has no initial fee but costs $0.18 for each
minute of calls.
Step-by-step explanation:
x = number of minutes
first cost function :
c(x) = 0.14x + 15
the second cost function :
c(x) = 0.18x
I guess, the question (not written in the description) is after how many minutes call time the first plan breaks even with the second plan and further becomes the better choice ?
0.18x = 0.14x + 15
0.04x = 15
x = 15/0.04 = 375
with 375 minutes calling time per month the first plan costs the same as the second plan.
and starting with 376 minutes per month the first plan becomes the cheaper option.
under 375 minutes per month the second plan is the cheaper option.
Factor completely
y^ 3-6y^2+5y
Answer:
please mark me as brainlist pleaseStep-by-step explanation:
The first term is, y2 its coefficient is 1 .
The middle term is, -6y its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
y2 - 5y - 1y - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-5)
Add up the last 2 terms, pulling out common factors :
1 • (y-5)
Step-5 : Add up the four terms of step 4 :
(y-1) • (y-5)
Which is the desired factorization
Is the inverse of a function always a function?explain
Answer:
Step-by-step explanation:
The inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element. (Each x and y value is used only once.)
Answer:
The inverse is not a function: A function's inverse may not always be a function. The function (blue) f(x)=x2 f ( x ) = x 2 , includes the points (−1,1) and (1,1) . Therefore, the inverse would include the points: (1,−1) and (1,1) which the input value repeats, and therefore is not a function.

A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Answer:
28 ft²
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex], where r = radius. To find the radius, we split the diameter in half.
6/2 = 3Thus, the radius is 3.Now, let's find the area of the circle and approximate pi to 3.14.
[tex]3.14*3^2[/tex] [tex]3.14*9[/tex] [tex]28.26[/tex] 28.26 ≈ 28 ft²Therefore, the answer is 28 ft².
Madeline uses a scale model of a design she plans to paint on a wall she uses the key 1 CM =1.5 ft. One gallon of paint will cover 400 square feet of wall .How many gallons of paint will Madeline use? Enter your answer as a decimal in the box.
Madeline would need to use 0.82 gallon of paint
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the scale 1 cm = 1.5 ft.
(1 cm)² = (1.5 ft.)²; 1 cm² = 2.25 ft²
The area of the figure = area of trapezoid + area of triangle
Area = (1/2) * (10) * (14 + 4) + (1/2) * 14 * (18 - 10) = 146 cm²
146 cm² = 146 cm² * 2.25 ft² per cm² = 328.5 ft²
1 gallon = 400 ft², hence:
328.5 ft² = 328.5 ft² * 1 gallon per 400 ft² = 0.82 gallon
Madeline would need to use 0.82 gallon of paint

28 is what percent of 64?
Solution:
Note that:
64 × x/100 = 28Simplifying the LHS:
64 × x/100 = 28=> 64x/100 = 28Using cross multiplication:
64x/100 = 28=> 64x = 2800Divide 64 both sides.
=> x = 2800/64 = 43.75%28 is 43.75% of 64

Chase found new pants for $35.55 plus 7.5% tax. What is the final price of the new pants?
Answer:
$38.22
Step-by-step explanation:
7.5% of $35.55 = $2.66625
= $2.67
$35.55 + 2.67 = $38.22 after tax
Answer:
$38.22
Step-by-step explanation:
Given the following question:
7.5% of 35.55
To find the answer we must first find 7.5% of 35.55 using the formula to calculate percentages, and then we add that answer to the current price of the pants.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7.5\times35.55}{100}[/tex]
[tex]7.5\times35.55=266.625[/tex]
[tex]266.625\div100=2.66625[/tex]
[tex]=2.66625[/tex]
Round the answer to the nearest cent:
[tex]2.66625[/tex]
[tex]6 > 5[/tex]
[tex]=2.67[/tex]
7.5% of 35.55 is "$2.67."
Now we add the answer to the current price:
[tex]35.55[/tex]
[tex]35.55+2.67=38.22[/tex]
[tex]=38.22[/tex]
The cost of the new pants after a 7.5% tax is "$38.22."
