Answer:
<em>4√5</em>
Step-by-step explanation:
The length of the radius of the circle will be the distance between the two coordinates. Using the formula:
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates (-4‚-2) and (-8‚-10)
R = √(-8-(-4))²+(-10-(-2))²
R = √(-4)²+(-8)²
R = √16+64
R = √80
R = √16*5
R = 4√5
<em>Hence the length of the radius of this circle is 4√5</em>
Answer:
I THINK a=3 b=9
Step-by-step explanation:
Answer:
D) 35 yards for $90.
Step-by-step explanation:
We have been given four options and we are asked to choose the option that represents the best deal.
Let us find the cost of per yard cloth for our given choices.
A.
Therefore, option A offers $4 per yard of cloth.
B.
Therefore, option B offers $3 per yard of cloth.
C.
Therefore, option C offers $2.75 per yard of cloth.
D.
Therefore, option D offers $2.57 per yard of cloth.
Since price offered by option D is less than other option D is the best deal.
Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:
h(t) = 10 - 0.75t
The height will be of 0.25 inches when h(t) = 0.25, hence:
0.25 = 10 - 0.75t
0.75t = 9.75
t = 9.75/0.75
t = 13 hours.

Jose should charge $0.65 for each bag if he intends to sell the bag for $0.15 more than he paid.
<h3>How do we solve word problems?</h3>
Mathematical problems dealing with word problems can be solved by arranging data given into variables and using the appropriate arithmetic operation to solve them.
From the given information:
If Jose bought a 750 bag of peanuts for $375.00. It means that he bought each bag(1 bag) for:

= $0.5
However, he intends to sell each bag for $0.15 more than he paid; Then the amount he should charge for each bag is:
=$0.5 + $0.15
=$0.65
