Answer:
Step-by-step explanation:
We want to find the unit price for the insulated socks, or the price per pair of insulated socks. To find the unit price, we must divide the cost by the pairs of socks.
We know that it costs $34.14 for 6 pairs of socks.
Divide.
The unit price is $5.69 per pair of insulated socks.
Answer:
$5.69
Step-by-step explanation:
34.14/6
=5.69
The unit price of the pairs of socks are $5.69.
Answer:
h(x) = 1/4 x - 2
Step-by-step explanation:
f(x) = 4x + 8
y = 4x + 8
x = 4y + 8
4y = x - 8
y = 1/4 x - 2
h(x) = 1/4 x - 2
Answer:
Any polynomial of the form f(x)=rx²+(1-4r)x+(3r+6) passes through these points.
Step-by-step explanation:
Let f(x)=rx²+bx+c be a polynomial that passes through (1,7) and (3,9). This means that f(1)=7 and f(3)=9, that is,
f(1)=r(1)²+b(1)+c=r+b+c=7, and
f(3)=r(3)²+b(3)+c=9r+3b+c=9
We have the equations r+b+c=7 and 9r+3b+c=9. Substract the second equation minus 9 times the first to obtain -6b-8c=-54, then 6b+8c=54 or equivalently b=9-4c/3.
Substract the second equation minus 3 times the first to obtain 6r-2c=-12. Then 2c=6r+12, thus c=3r+6. We have written c in terms of r. Substitute in b=9-4c/3 to obtain b=9-4(r+2)=-4r+1. The polynomial acquires the form
f(x)=rx²+(1-4r)x+(3r+6).

The dimensions increased by 4 feet.
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Given;
Dimensions of rectangle = 12 + x and 14 + x
The area of the rectangle= (12 + x) (14 + x) = 288
x² + 26x + 168 = 288
x² + 26x - 120 = 0
(x + 30) (x - 4) = 0
x=-30, x =4
Hence, The dimensions increased by 4 feet.

Answer: 7
Step-by-step explanation:
For c, we are given this sum from 1 to 3 of . 1/2 is a constant , therefore, we can move it outside of the summation.
*I hope you can understand what I'm saying. I can't figure out how to type in summations into the equations section.
1/2∑₁³n²
This means you would multiply the sum of n² from 1 to 3 by 1/2.
We are told n=1 to n=3 so we would plug 1, 2, 3 into n.
1²=1
2²=4
3²=9
We would add them together since that is what the sum sign tells us to do.
1+4+9=14
Now that we know the sum, we multiply it with 1/2
14/2=7
