The explicit rule for a sequence and one of the specific terms is given. Find the position of the given
term
f(n) -5.5n - 52;25
25 is the BLANK th term
Answer:
25 is the 14th term.
Step-by-step explanation:
The nth term of a sequence is given by the following explicit rule:
f(n) =5.5n - 52
We need to find the position n of the term of value 25. In other words, find n in the equation:
5.5n - 52=25
Adding 52:
5.5n =25+52=77
Solving:
n=77/5.5
n=14
25 is the 14th term.

Answer:
RHS
Step-by-step explanation:
It is given that XY is the perpendicular bisector of WZ. This means that it forms 90-degree angles at Y. (angle XYZ and angle XYW are 90 degrees). (R)
Since there is a right angle at Y, XZ and XW are the hypotenuses. (H)
There is a common line between triangle XYZ and XYW and that is XY. (S)
Therefore you can prove ΔXYZ ≅ΔXYW because of RHS
Jim received notice from his employer that the equation to calculate his salary was changing. Currently he makes $300 per week plus 4% commission on sales. The new equation will be $450 plus 2% commission on sales. Which equation shows the amount in sales he will need for his salary to be the same?
Answer:
Sales= $750Step-by-step explanation:
let sale be x
and his salary be y
y=300+0.4x----------1 the old equation
y=450+0.2x----------2 the new equation
for his salary to be the same
equation 1 and 2 must be equal hence
300+0.4x=450+0.2x
solving for x we have
300-450+0.4x-0.2x=0
-150+0.2x=0
0.2x=150
x=150/0.2
x=$750

In what form is an equation that relates two proportional quantities x and y?
Oy=k+x, where k is the constant of proportionality
O y = kx, where k is the constant of proportionality
k
where k is the constant of proportionality
O y
y=
k
where y is the constant of proportionality
Answer:
B. [tex] y = kx [/tex] , where k is the constant of proportionality.
Step-by-step explanation:
Given that quantity x and y is directly proportional to each other, which means as one variable increases, the other increases as well. Thus, the constant of proportionality, which is often denotes with the alphabet k, can be represented by the following equation:
[tex] y = kx [/tex] , where, k is the constant of proportionality.
Constant of proportionality, k, is gotten when you divide the value of y by the value of x.

Answer:
105
Step-by-step explanation:
since its a straight line it would add up to 180 degrees so 52 + 23 + 75 and you need 180 so 180-75 which gives 105 which is the missing angle
Answer:
105 degrees
Step-by-step explanation:
First add the angles that you already know, 52 + 23 = 75, then since we know that the whole thing is a straight angle (180 degrees) 180-75 = 105 degrees.
Hope this helped!

What is mass if force is 45 N and acceleration is 39 m/s/s?
Answer:
The answer is 1.15 kgStep-by-step explanation:
To find the mass of an object given it's acceleration and the force acting on it we use the formula
[tex]mass = \frac{force}{acceleration} \\ [/tex]
From the question
force = 45 N
acceleration = 39 m/s²
We have
[tex]force = \frac{45}{39} = \frac{15}{13} \\ = 1.153846...[/tex]
We have the final answer as
1.15 kgHope this helps you

If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?
Let's see what to do buddy...
____________________________
Reminder:

So we need to just Multiply above equations like this :
[tex]x + y = 70[/tex]
[tex]x - y = 40[/tex]
[tex](x + y)(x - y) = 70 \times 40[/tex]
[tex] {x}^{2} - {y}^{2} = 2800 [/tex]

Online, Terrell found a soup recipe that requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil. For a big event, Terrell wants to make a huge pot of soup. If he uses 1 teaspoon of dried basil, how much pepper should he use?
Answer:
He should use 1/2 of a teaspoon of pepper.
Step-by-step explanation:
From the question, the soup recipe requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil.
Now, to determine how much pepper Terrell should use if he uses 1 teaspoon of dried basil for the huge pot of soup,
Let the quantity be x
If 1/4 of a teaspoon of pepper requires 1/2 of a teaspoon of dried basil,
then, x teaspoon of pepper will require 1 teaspoon of dried basil
x = (1/4 × 1) ÷ (1/2)
x = 1/4 ÷ 1/2
x = 1/4 × 2/1
x = 2/4
x = 1/2
∴ 1/2 of a teaspoon of pepper is required for 1 teaspoon of dried basil.
Hence, he should use 1/2 of a teaspoon of pepper.
