Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 45 - 135.
The sum using summation notation will be - 312. The sum of the following progression is found by the formula as [tex]S_n = \frac{a(1 - r^n)}{(1 - r)}[/tex].
What is geometric progression?Geometric Progression (G.P.) is a sort of sequence in which each successive phrase is obtained by multiplying the prior term by a set number known as a common ratio.
This progression is also known as a pattern-following geometric sequence of integers. Here you may also learn about mathematical progression.
A non-zero value is obtained by multiplying the common ratio by each phrase to obtain the next term 5 - 15 45 - 135.. is an example of a geometric series with a common ratio of -3.
The common ratio will be;
[tex]\rm r= \frac{-15}{3} \\\\ \rm r= -5[/tex]
The first term is 3
So the sum using summation notation will be;
[tex]S_n = \frac{a(1 - r^n)}{(1 - r)} \\\\ S_n = \frac{3(1 - (-5)^4)}{(1 - (-5))} \\\\ S_n =- 312[/tex]
Hence the sum using summation notation will be - 312.

A few students finished up their NCVPS work early and are playing skip
rope. As the rope rotates it is observed that its maximum height is 2.75m
after 1 second. The first minimum height of 0.25m occurs 2 seconds after
the maximum height. Sketch a graph to model the situation.
Answer:
see attached
Step-by-step explanation:
The graph can be shown as a sine wave with a maximum of 2.75 m and a minimum of 0.25 m. Its period will be twice the time from maximum to minimum, so will be 2×2 seconds = 4 seconds. The midline of the graphed function will be halfway between the extremes, at 1.5 m.
The equation of the graph will put the first peak at 1 second, so if a cosine function is used, it will have a horizontal shift of 1 second to the right.

round of 38828 to the nearest 10
Step-by-step explanation:
We're going to be evaluating if we can round 2. (Values in the 10's place)
The value in the 'ones' place has to be greater than or equal to 5 in order to round up 2.
Since 8 is greater than 5, we can round up 2.

Find the area of the iscoselies triangle when the base is 10cm and hypotenuse is 13
hope it helps
please give brainliest
Step-by-step explanation:
.
Answer:
[tex]\sf\: Area \: of \: the \: triangle \: = \boxed{\boxed{\bf\:50 \: cm^{2}}}[/tex]
Step-by-step explanation:
Given,
The triangle is an isosceles triangle.
Base (b) = 10 cmHypotenuse = 13 cmAltitude (h) = Base = 10 cm [isosceles triangle has equal opposite sides]Since, we are given the hypotenuse, the triangle will be an isosceles right angled triangle.
We know that, area of a right angled triangle = ½ × b × h
By substituting the values in the above formula...
½ × b × h
= ½ × 10 × 10
= ½ × 100
= [tex]\boxed{\boxed{\bf\:50 \: cm^{2}}}[/tex]

3×-6=3
3×=3+6
3×=9
×=3
Step-by-step explanation:
multiply 3 by the variables in the bracket.
then you will get 3×-6=3.
take the -6 to the right hand side and it becomes+6
then you get 3×=3+6 therefore =3×=9
then divide both sides by 3.
3×÷3 and 9÷3

If 15 men can do a piece of work in 30 days, in how many days can 10 men complete the same work?
Answer:
45
Step-by-step explanation:
n/15=30
therefore n=450
hence n/10 = 45
Answer:
45 days
Step-by-step explanation:
If 15 men = 30 days
1 man=30*15
1 man = 450 days
10 men = 450/10=45

Give your answer rounded to 3 significant figures.
Answer:
10.8 =x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8.8 ^2 + 6.2 ^2 = x^2
77.44+38.44=x^2
115.88=x^2
Take the square root of each side
10.76475731=x
Round to 3 significant figures.

Please help, explain in words the steps needed to solve this problem
Answer:
x=6
Step-by-step explanation:
By the Product Rule of Logarithms, the logarithm of the product of numbers is the sum of the logarithms of the numbers.
[tex] log(x) + log(x - 1) = log(x(x - 1)) = log( {x}^{2} - x ) = log(3x + 12) [/tex]
Raise both sides to the power of 10 to eliminate the logs, obtaining:
[tex] {x}^{2} - x = 3x + 12[/tex]
[tex] {x}^{2} - 4x - 12 = 0[/tex]
[tex](x - 6)(x + 2) = 0[/tex]
x = -2 or x = 6. Since x = -2 is extraneous, it follows that x = 6.
A taxi ride costs $3 plus $2.50 per mile. Write and graph an equation that represents the total cost of a taxi ride. Let m represent number of miles and c represent the total cost (in dollars) of the taxi ride. What is the total cost of a five-mile taxi ride?
Answer:
The answer is 3 + 2.50m = c.
Step-by-step explanation:
You would use the slope equation: y = mx+b where y is equal to the total cost of a taxi ride, in dollars and m is equal to the number of miles. $3 is your base cost which represents your y-intercept or your b and $2.50 represents your slope.

Answer:
Step-by-step explanation:
A store is having a sale in which all bookbags are discounted by `30\%`. Mai has a coupon for `\$5` off the regular price of one bookbag. The store first applies this coupon, and then takes `30\%` off the reduced price. Mai pays `\$23.10` for the bookbag.
You said the equation represents this scenario, and the solution to your equation was `\$35.56`.
Explain what the solution to the equation means within the context of the problem.
The regular price of the book bag was $38.
EquationAn equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the regular price of the bag. After applying the coupon:
Price = x - 5
After the discount:
23.10 = (x - 5) - 30% of (x - 5)
23.10 = (x - 5) - (0.3x - 1.5)
0.7x - 3.5 = 23.10
x = 38
The regular price of the book bag was $38.

Answer:
8 crabs and 2 octopi
Step-by-step explanation:
Let c represent the amount of crabs and o represent the amount of octopi.
We can use this to set up a system of equations:
6c+8o=64
c=4o
We can solve this system using substitution. In this case, we can substitute 4o for c:
6(4o)+8o=64
24o+8o=64
Combine like terms
32o=64
Divide both sides by 32
o=2
Substitute 2 for o to solve for c:
c=4o=4(2)=8
There are 8 crabs and 2 octopi
