Answers
Answer:
a. Angel has a greater flat fee
b. Difference = $130
Step-by-step explanation:
Given
Rose:
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
Angel
Guests --- Charges
10 -------- $180
15 -------- $255
25 -------- $405
30 -------- $480
Solving (a): Who charges the greater flat fee?
We have that the flat fee of Rose is:
\(Flat\ Fee = \$50\)
For Angel, we need to determine the equation of the given table
Start by calculating the slope (m) of the table
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where x and y represent any two corresponding values of the guests and the charges.
\((x_1,y_1) = (10, 180)\)
\((x_2,y_2) = (30, 480)\)
So: \(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes
\(m = \frac{480 - 180}{30 - 10}\)
\(m = \frac{300}{20}\)
\(m = 15\)
Next, we calculate the equation using:
\(y - y_1 = m(x - x_1)\)
Where
\(m = 15\)
\((x_1,y_1) = (10, 180)\)
\(y - 180 = 15(x - 10)\)
\(y - 180 = 15x - 150\)
Add 180 to both sides
\(y - 180 + 180 = 15x - 150 + 180\)
\(y= 15x + 30\)
From the equation above:
The slope = 15 --- This represents the hourly rate
and
y intercept = 30 --- This represents the flat fee
This is better represented as:
Angel
\(Flat\ Fee = \$30\)
\(Rate = \$15\)
and
Rose:
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
By comparison, Angel has a greater flat fee
Solving (b): Difference between total charges of 50 guests for both caterers.
For angel, the equation is:
\(y= 15x + 30\)
and x = 50.
So:
\(y = 15 * 50 + 30\)
\(y = 750 + 30\)
\(y = 780\)
For Rose,
First, we need to determine the equation.
\(Flat\ Fee = \$50\)
\(Rate = \$12\)
The equation is:
\(y = Flat\ Fee + Rate * x\)
\(y = 50 + 12 * x\)
So, the total charges for 50 guests is:
\(y = 50 + 12 * 50\)
\(y = 50 + 600\)
\(y = 650\)
The difference is then calculates as:
\(Difference = 780 - 650\)
\(Difference = \$130\)

(Simplify your answer.)
Answers
Answer:4x+3
Step-by-step explanation:
Given the following in the question if:
Volume of the box= 4x3+19x2+12z
Height of the box= x
width of the box =?
we have to find the width of the box, so as we know that
box is in the shape of cuboid, so
Volume of the cuboid = length * width * height
4x3+9x2+12x = x+4* width * x
width = 4x3+9x2+2x/x2+4x
we have to use long division method for this algebraic expression to divide and find width of the box.
we get width= 4x+3
Hence, the width of the box which in the shape of cuboid is 4x+3

Select the best estimate of the capacity of a bath tub. A. 5 ml B. 500 ml C. 50 cl D. 500 L.
Answers
Answer:
D. 500 L
because ml cl is smaller than L
Answer:
D. 500 L
Step-by-step explanation:
Choice A (5 ml) is basically a teaspoon. A bathtub can most definitely hold much more then one teaspoon of water.
Choice B (500 ml) is about 17 ounces. Which is basically the amount of water in a normal water bottle. A bathtub can hold more then the amount of water in one water bottle.
Choice C (50 cl) is a little bit more then 2 cups of water. I believe a normal bathtub can hold about 1280 cups of water.
That rules out choices A, B, and C. By process of elimination, we can tell choice D is the answer. But let's just take a look at D.
Choice D (500 L) is about 132 gallons. This is the most plausible one, although some bathtubs don't hold as much water as that, it still is the best estimate of the capacity of a bath tub. \

Answers
The next term in the sequence is 98. None of the given options (60, 81, 90, 101) match the expected next term. None of the option is correct.
To find the pattern in the sequence 1, 1, 3, 8, 19, 41, we can examine the differences between consecutive terms:
1 1 3 8 19 41
0 2 5 11 22
Looking at the differences, we can observe that each subsequent difference is obtained by adding consecutive odd numbers: 2, 3, 4, 5, etc. This suggests that the original sequence may be related to square numbers.
Let's check if the differences between consecutive terms are square numbers:
2 = 1²
5 = 2² + 1²
11 = 3² + 2²
22 = 4² + 3²
Based on this pattern, we can make a reasonable assumption that the next difference should be 5² + 4² = 41 + 16 = 57. Adding this difference to the last term of the sequence (41), we get the next term:
41 + 57 = 98
Therefore, the next term in the sequence is 98. None of the given options (60, 81, 90, 101) match the expected next term.
Hence, none of the given options accurately continue the pattern of the sequence. It's important to note that patterns in sequences can sometimes have multiple possible interpretations, and it's always essential to consider alternative patterns or extend the sequence further to confirm the pattern.

f(x +h) = 4x² +4h² +8xh +5x +5h +3
(f(x+h) -f(x))/h = 4h +8x +5
f'(x) = 8x +5
Step-by-step explanation:
For f(x) = 4x² +5x +3, you want the simplified expression f(x+h), the difference quotient (f(x+h) -f(x))/h, and the value of that at h=0.
F(x+h)Put (x+h) where h is in the function, and simplify:
f(x+h) = 4(x+h)² +5(x+h) +3
= 4(x² +2xh +h²) +5x +5h +3
f(x +h) = 4x² +4h² +8xh +5x +5h +3
Difference quotientThe difference quotient is ...
(f(x+h) -f(x))/h = ((4x² +4h² +8xh +5x +5h +3) - (4x² +5x +3))/h
= (4h² +8xh +5h)/h
(f(x+h) -f(x))/h = 4h +8x +5
LimitWhen h=0, the value of this is ...
f'(x) = 4·0 +8x +5
f'(x) = 8x +5
__
Additional comment
Technically, the difference quotient is undefined at h=0, because h is in the denominator, and we cannot divide by 0. The limit as h→0 will be the value of the simplified rational expression that has h canceled from every term of the difference. This will always be the case for difference quotients for polynomial functions.

The concept of best-, worst-, and average-case analyses extends beyond algorithms to other counting problems in mathematics. Recall that the height of a binary tree is the number of edges in the longest path from the root to a leaf. Find the best-case height of a binary tree with seven nodes.
Answers
the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.
A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

the equation of a circle centered at the origin x^2 + y^2 = 64. what is the radius of the circle?
Answers
Answer:
r = 8 units
Step-by-step explanation:
The equation of the circle centered at the origin is x² + y² = r²
x² + y² = 64
x² + y² = 8²
r = 8 units
Answer:
8
Step-by-step explanation:
An equation of a circle is depicted by the notation \((x-h)^2+(y-k)^2=r^2\), where
- \((h,k)\) is the center point of the circle
- \(r\) is the radius (the span of units from the origin to the border of the circle)
In this unique problem, the center is the origin (0,0), so \(h\) and \(k\) respectively equal 0.
Since the equation of the circle is \(x^2+y^2=64\) , we must square root 64 since it's in it's \(r^2\) form to obtain the value of \(r\), which is the radius.
\(\sqrt{64}\)=±8
Despite mathematically, -8 or 8 will work in this case, you cannot have a negative radius; therefore, the radius of the circle is 8.

Answers
Answer:
Interest = $1897.09 Account Balance = $4397.09
Step-by-step explanation:
2500 x 1.019 = $4397.09 = Account Balance
4397.09 - 2500 = $1897.09 = Interest
The interest will the customer earn in 30 years is $1350, the account balance be after 30 years is $3850 and the customer earn $1350 interest.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.
In the given that new bank customer with $2,500 wants to open a money market account. The bank is offering a simple interest rate of 1.8%.
So, the Principal Amout(P) =$2500
Interest Rate(R) = 1.8%
(a) So we need to find the interest will the customer earn in 30 years.
the time (T)=30 years
Simple Interest; I=PRT/100
I=2500*1.8*30/100
I=1350
thus the interest will the customer earn in 30 years is $1350.
(b) Now we need to find the account balance be after 30 years.
The account balance = Principal Amount+Interest Amount
The account balance = 2500+1350
The account balance = $3850
(c) Now we have to find the customer will earn $ in interest.
