A cookware consultant sells two types of pizza stones. The circular(e) stone sells for $26 and the rectangular (r) one sells for $34. In one month she sold 37 stones. If she made a total of $1138 from the sale of the pizza stones, how many of each size did she sell?
Answers
Answer:
Step-by-step explanation:
Conditions
Let the circular stones = x
Let the rectangular stones = y
Equations
x + y = 37 Subtract x from both sides of this equation.
y = 37 - x Notice that x is on the right side of the equation
Solution
26x + 34y = 1138 Substitute for y
26x + 34(37 - x) = 1138 Remove the brackets
26x + 1258 -34x= 1138 Combine
-8x + 1258 = 1138 Subtract 1258 from both sides
-8x +1258-1258 = 1138-1258 Combine.
-8x = -120 Divide both sides by -8
-8x/-8 = -120/-8
x = 15 Two minuses make a plus (last step)
x+ y = 37
15 + y = 37 Subtract 15 from both sides
15-15 +y = 37-15 Combine
y = 22
Answer
x = 15 Circular pizza dishes
y = 22 square pizza dishes
The consultant sold 15 circular pizza stones and 22 rectangular pizza stones.
How to determine how many of each size did she sell?Let's assume the number of circular pizza stones sold is "c" and the number of rectangular pizza stones sold is "r."
We are given two pieces of information:
1. The total number of stones sold: c + r = 37
2. The total amount earned from the sale of the stones: 26c + 34r = 1138
Now, we can use these two equations to solve for the values of "c" and "r."
First, let's use the first equation to express "c" in terms of "r":
c = 37 - r
Now, substitute this value of "c" into the second equation:
26c + 34r = 1138
26(37 - r) + 34r = 1138
962 - 26r + 34r = 1138
Combine the "r" terms:
8r = 1138 - 962
8r = 176
Now, divide by 8 to find the value of "r":
r = 176 / 8
r = 22
Now that we have the value of "r," we can find the value of "c" using the first equation:
c = 37 - r
c = 37 - 22
c = 15
So, the consultant sold 15 circular pizza stones and 22 rectangular pizza stones.

By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.
How to find the value the elements of a sequence by recurrence formula
Sequences are sets of values defined by at least one condition. In this case, we have three conditions to generate the required values:
f(n) = f(n/5) + 3 · n
f(1) = 4
[tex]n \in \mathbb{N}[/tex]
Now we proceed to find the elements by recurrence:
f(5) = f(1) + 3 · 5
f(5) = 4 + 15
f(5) = 19
f(25) = f(5) + 3 · 25
f(25) = 19 + 75
f(25) = 94
f(125) = f(25) + 3 · 125
f(125) = 94 + 375
f(125) = 469
f(625) = f(125) + 3 · 625
f(625) = 469 + 3 · 625
f(625) = 469 + 1875
f(625) = 2344
f(3125) = f(625) + 3 · 3125
f(3125) = 2344 + 9375
f(3125) = 11719
By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.

For question b, you divide 312 by 4 which would give you 78 terms. This is because the ending term is 319 and the starting term is 7, but since it didn’t start at 1, you had to subtract 319 from 7 to get 312, and then divide 312 by 4, because each term rises by 4.
For question c, you subtract 533 from 33, which would give you 500 terms. This is because it didn’t start at 0, so you have to subtract from the term it started on, which was 33.

This gives
r = -18 / √((90)(692.8)) = -0.0721
So, the correlation coefficient is -0.0721
The above is a negative correlation because it is less than 0 and it is a weak correlation because it is closer to 0 than -1

For each of the transformed square root functions, state the transformations and use them to plot the
transformed function on the same graph with the parent function.
Answers
Step-by-step explanation:
so, if I understand this correctly, the original function (shown in the graph) is
f(x) = sqrt(x)
the following transformations were done going from f(x) to h(x) :
x -> x + 4 as variable term moved the whole curve 4 units to the left. because now a specific functional value is calculated for a smaller x (by 4 units) than for the original f(x). e. g. let's call g(x) = sqrt(x + 4). then g(-4) = f(0). as mentioned, everything moved over to the left by 4 units.
sqrt(x) -> 3×sqrt(x) increased the range of the function (the generated y values) by the factor 3. was the functional result for a x value = 1, then it is now 3 for the same x value.
sqrt(x) -> sqrt(x) - 1 moved the whole curve down by 1 unit.
in summary, the whole original curve was moved 4 units to the left, then stretched upwards by the factor 3, and then that result was moved down by 1 unit.
so, e.g.
h(-4) = 3×f(0) - 1 = -1 point (-4, -1) corresponds to old (0, 0)
h(-3) = 3×f(1) - 1 = 2 point (-3, 2) corresponds to old (1, 1)
h(0) = 3×f(4) - 1 = 5 point (0, 5) corresponds to old (4, 2)

Principal

Rate

Compounded

Time

Answers
Step-by-step explanation:
So the general formula for compound interest is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where t is typically time in years, and n is how many times it's compounded per year. But in this case it's only compounded 1 time per year so the equation is just [tex]A = P(1+r)^t[/tex]. in this case P is the principal amount, r is the interest, and A is the final amount. So the 5% interest rate becomes 0.05 by dividing by 100 to convert it into decimal form and the principle amount of 11,000. This gives you the formula [tex]A = 11000(1.05)^t[/tex]. This is the answer to the first question where t is the time in years. When it says "Find interest earned" I'm a bit confused, is it giving you x amount of years where you have to calculate the interest earned or does it want a general equation? Because the general equation would be the final amount - the principle amount which calculates the difference. So the equation for interest earned would be [tex]11000(1.05)^t-11000[/tex]. To calculate the amount of money after 5 years you simply plug in 5 as t. this gives you the equation [tex]11000(1.05)^5 \approx 11000(1.276) \approx 14,039.10[/tex]
