Answer:
Earning for 1950- word article = $1170
Step-by-step explanation:
Given that:
Amount paid for 1300 word article = $780
Ratio of words to money = 1300 : 780
Let,
x be the amount for 1950 words.
Ratio of words to money = 1950 : x
As the relationship is proportional
1300 : 780 :: 1950 : x
Product of mean = Product of extreme
780 * 1950 = 1300x
1300x = 1521000
Dividing both sides by 1300
[tex]\frac{1300x}[1300}=\frac{1521000}{1300}\\x=1170[/tex]
Hence,
Earning for 1950- word article = $1170

Consider the function f(x) = x^2 - 6x + 5
a. What are the x-intercepts of the function?
b. Does the function have a line of symmetry? if so, what is it?
c. Does the function have a maximum or minimum value? Explain how you know without graphing.
Answer:
Step-by-step explanation:
a. the question can be factored as (x-5)(x-1) so the 2 x intercepts are 5 and 1
b. yes the function has a line of symmetry every parabola does and it is at when x is 3
x. the function has a minimum value because the equation has x^2 which is 1x^2 1 is a positive meaning that the function opens upward which means it has a minimum value
Answer:
A)
(1, 0) and (5, 0)
B)
Yes.
The equation is x = 3.
C)
Yes.
In this case, we have a minimum.
Step-by-step explanation:
We are given the function:
[tex]f(x)=x^2-6x+5[/tex]
Since the highest degree is two, we can immediately determine this to be a quadratic.
A)
The x-intercepts of a function are whenever the function equates to 0. Hence:
[tex]0=x^2-6x+5[/tex]
We can factor:
[tex](x-1)(x-5)=0[/tex]
Zero Product Property:
[tex]x-1=0\text{ or } x-5=0[/tex]
Solving yields:
[tex]x=1 \text{ and } x=5[/tex]
So, our x-intercepts are at (1, 0) and (5, 0).
B)
Since this is a quadratic, it indeed has a line of symmetry.
Recall that the line of symmetry for a quadratic equivalent to the x-coordinate of the vertex.
In the given function, a = 1, b = -6, and c= 5.
Hence, the x-coordinate of the vertex is:
[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(-6)}{2(1)}=\frac{6}{2}=3[/tex]
So, the line of symmetry is x = 3.
C)
Every parabola has a minimum/maximum value.
This depends on the sign of the leading coefficient.
If the leading coefficient is positive, then we have a minimum since our parabola will be curving upwards.
And if the leading coefficient is negative, then we have a maximum since our parabola will be curving downwards.
Since our leading coefficient here is 1, hence positive, we have a minimum value.

You want to put a 3 inch thick layer of topsoil for a new 13 ft by 31 ft garden. The dirt store sells by the cubic yards. How many cubic yards will you need to order
Answer:
30 cubic yards
Step-by-step explanation:
You will multiply 13 by two because there is two sides of 13ft
13 x 2 = 26
Then do the same thing with 31, so 31 multiply by 2
31 x 2 = 62
After that add 62 and 26
62+26=88
Then divide 88 by 3
88÷3=29.9
after that you will round 29.9 by the nearest 10 which is 30

Solve for x 3 x − 8 = 6 x − 2
Answer:
x = -2
Step-by-step explanation:
3x - 8 = 6x - 2
Isolate x.
3x = 6x - 2 + 8
3x - 6x = 6
-3x = 6
x = 6 ÷ -3
x = -2

find a formula for the nth term in this arithmetic sequence. a1=0, a2=0.5, a3=1, a4=1.5
Answer:
nth term is;
0.5n-0.5
Step-by-step explanation:
As we can see, the first term is 0
The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5
Formula for nth term of an arithmetic sequence is;
a + (n-1)d
So we have
0 + (n-1) 0.5
= 0.5n-0.5

Answer:
3) ? = 21
4) ? = 6
Step-by-step explanation:
3) The given ratio is ...
A : B = 2 : 7
You want to find ? such that ...
2 : 7 = 6 : ?
The ratio is equivalent when both numbers are multiplied by the same value.
From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.
__
4) For this one, you need to recognize that the given number corresponds to B.
A : B = 2 : 3
2 : 3 = ? : 9
Again, you know that 3×3 = 9, so 3×2 = ? = 6.

The sum of ages of two ship 12years old .Two years ago, the age of the older ship was three times the age of the newer ship. Find the present age of each ship.
Answer:
the present age of the old ship is 8 years
The present age of the new ship is 4 years
Step-by-step explanation:
Let the age of the older ship be x
Let the age of newer ship be y
If the sum of ages of two ship 12years old, then;
x + y = 12 .... 1
Two years ago;
Older ship age = x - 2
New ship age = y - 2
If two years ago, the age of the older ship was three times the age of the newer ship, then;
x - 2 = 3(y-2)
x-2 = 3y - 6
x = 3y - 4 ....2
Substitute equation 2 into 1;
From 1; x+ y = 12
3y-4+y = 12
4y = 12 + 4
4y = 16
y = 4
Since x+y = 12
x = 12-y
x= 12-4
x = 8
Hence the present age of the old ship is 8 years
The present age of the new ship is 4 years

Suzie needs to borrow $6,000 from a local bank. What is the monthly payment for a one year, 11.25% loan?
Given :
Suzie needs to borrow $6,000 from a local bank.
Interest rate, r = 11.25%.
To Find :
The monthly payment of Suzie for one year to pay of the loan.
Solution :
Total amount to return is :
[tex]A = 6000 + \dfrac{6000\times 11.25}{100}\\\\A =\$6675[/tex]
Let, monthly payment is x.
So,
[tex]x =\$ \dfrac{6675}{12}\\\\x = \$556.25[/tex]
Therefore, the monthly payment for loan is $556.25 .

At an electronics store, a smart phone is on sale for 35% off the original price of $679. If you use the store credit card, you can receive an additional 15% off the sale price. What is the final price of the smart phone if you use the store credit card? Round to the nearest cent.
Answer:
%375.15
Step-by-step explanation:
Hope this helps u out
Answer:
The final price of the smartphone is $375.15
Step-by-step explanation:
Percentages
The original price of a smartphone at an electronics store is $679. The store is on sale for 35% off that price.
Thus the sale price can be calculated by subtracting the discount from the original price.
Discount= 35% of $679 = 35/100 * $679 = $237.65
Sale price=$679 - $237.65 = $441.35
If you use the store credit card, there is an additional discount of 15% off the sale price. The new discount is:
New discount = 15% of $441.35 = $66.20
And the final price is: $441.35 - $66.20 = $375.15
The final price of the smartphone is $375.15
