A line passes through the point (1,5) and has a slope of 7
Answers
Therefore, the equation of the line passing through the point (1,5) with a slope of 7 is y = 7x - 2.
The equation of a line in the point-slope form is given by the following equation:
y-y_1 = m(x-x_1)
where m is the slope of the line and (x1, y1) is any point on the line.
Therefore, we can write the equation of the line passing through the point (1,5) with a slope of 7 as follows:
y-5 = 7(x-1)
Expanding the right-hand side of the equation gives:
y-5 = 7x-7
Adding 5 to both sides of the equation gives:
y = 7x-2

Answers
A. In equation form: Revenue = 9x1 + 12x2 + 4x3 + 5x4 + 8x5
B. Non-negativity constraint: x1, x2, x3, x4, x5 ≥ 0
How did we get these values?To solve this problem using E x c e l Solver, set up the revenue function and the constraints. Here's how you can do it:
a. Revenue Function:
Let's denote the number of cakes baked for each type as x1, x2, x3, x4, and x5 respectively.
The revenue function can be formulated as:
Revenue = (Selling Price of Cake 1 × Number of Cake 1) + (Selling Price of Cake 2 × Number of Cake 2) + (Selling Price of Cake 3 × Number of Cake 3) + (Selling Price of Cake 4 × Number of Cake 4) + (Selling Price of Cake 5 × Number of Cake 5)

- Calculate CV for the following numbers: 5, 8, 9, 2, 6. OA. 40.82 B. 120 OC. 0.4083 OD. 1.2
Answers
The coefficient of variation or CV of the given numbers is 45.64%.
Given numbers are,
5, 8, 9, 2, 6
We have to find Coefficient of variation.
CV = (Standard deviation / sample mean ) × 100
Sample mean = Sum of the values / total number of values
= (5 + 8 + 9 + 2 + 6) / 5
= 6
Standard deviation = √[(Σ(x - mean)² / (n - 1)]
Σ(x - mean)² = (5 - 6)² + (8 - 6)² + (9 - 6)² + (2 - 6)² + (6 - 6)²
= 30
Standard deviation = √(30 / (5 - 1) = 2.7386
CV = (2.7386 / 6) × 100
= 45.64%
Hence CV is 45.64%.

If a snowball melts so that its surface area decreases at a rate of 3 cm2/min, find the rate at which the diameter decreases when the diameter is 10 cm.
Answers
Answer:
The diameter decreases at a rate of -0.0477 cm/min when it is 10 cm.
Step-by-step explanation:
Surface area of a snowball:
A snowball has a spheric format, which means that it's surface area is given by:
\(A = 4\pi r^2\)
In which r is the radius, which is half the diameter. In function of the diameter, the area is given by:
\(A = 4\pi(\frac{d}{2})^2 = \pi d^2\)
Solving the question:
To solve this question, we have to implicitly derivate the area in function of t. So
\(\frac{dA}{dt} = 2d\pi\frac{dd}{dt}\)
Snowball melts so that its surface area decreases at a rate of 3 cm2/min
This means that \(\frac{dA}{dt} = -3\)
Find the rate at which the diameter decreases when the diameter is 10 cm.
This is \(\frac{dd}{dt}\) when \(d = 10\). So
\(\frac{dA}{dt} = 2d\pi\frac{dd}{dt}\)
\(-3 = 20\pi\frac{dd}{dt}\)
\(\frac{dd}{dt} = -\frac{3}{20\pi}\)
\(\frac{dd}{dt} = -0.0477\)
The diameter decreases at a rate of -0.0477 cm/min when it is 10 cm.

Phu takes out a $2,400 discounted loan using a simple interest rate of 8% for a period of 18 months. What is the effective interest rate, re
Answers
Answer:
9.1
Step-by-step explanation:
To calculate the total interest payable, we use the formula
I=P0rt,
and substituting our values yields
I=$2,400×0.08×1812=$288.
Therefore the total amount he receives at loan drawdown is $2,400−$288=$2,112. To calculate the effective interest rate, we use to formula
A=P0(1+ret).
In this instance we have A=$2,400,P0=$2,112 (redefined from the value above) and t=1.5. We substitute into the formula to get
$2,400=$2,112(1+1.5re).
Solve for re.
24002112=1+1.5re
24002112−1=1.5re
24002112−11.5=re
This gives re=0.0909⋯=9.0909…%, which is 9.1%

A. f(3) is larger.

After analyzing, it can be concluded that the functions f and g are:
A. f(0) is larger than g(0).
B. f(3) is larger than g(3).
Two Functions is LargerTo determine which of the two functions is larger at any given point, one must compare the heights of the two functions at the same point on the x-axis. At point x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0).
Similarly, at point x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3).
To compare which of two functions is larger at any given point, we need to compare the heights of the two functions at the same point on the x-axis. For example, at x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0). The same comparison can be made at any other point on the x-axis.
For example, at x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3). This comparison can be done for any point on the x-axis, which will allow us to determine which of the two functions is larger at any given point.

AB = 28 , BC = 17.5 , X = 13.2
Step-by-step explanation:
since the figures are similar then the ratios of corresponding sides are in proportion, that is
\(\frac{AB}{PQ}\) = \(\frac{AD}{PS}\) ( substitute values )
\(\frac{AB}{8}\) = \(\frac{14}{4}\) ( cross- multiply )
4 AB = 8 × 14 = 112 ( divide both sides by 4 )
AB = 28
and
\(\frac{BC}{QR}\) = \(\frac{AD}{PS}\) ( substitute values )
\(\frac{BC}{5}\) = \(\frac{14}{4}\) ( cross- multiply )
4 BC = 5 × 14 = 70 ( divide both sides by 4 )
BC = 17.5
similarly for the 2 similar figures
\(\frac{x}{6}\) = \(\frac{11}{5}\) ( cross- multiply )
5x = 6 × 11 = 66 ( divide both sides by 5 )
x = 13.2
Answer:
\(\overline{AB}=28\)
\(\overline{BC}=17.5\)
\(x=13.2\)
Step-by-step explanation:
Question 4If quadrilateral PQRS is similar to quadrilateral ABCD, their corresponding sides are in the same ratio:
\(\overline{PQ} : \overline{AB} = \overline{QR} : \overline{BC} = \overline{RS} : \overline{CD} = \overline{SP}:\overline{DA}\)
From inspection of the two quadrilaterals, the given side lengths are:
\(\overline{PQ} = 8\)
\(\overline{QR} = 5\)
\(\overline{RS} = 6\)
\(\overline{SP} = 4\)
\(\overline{DA} = 14\)
Substitute these into the ratio equation:
\(8 : \overline{AB} = 5 : \overline{BC} = 6 : \overline{CD} = 4:14\)
Solve for AB:
\(8 : \overline{AB} = 4:14\)
\(\dfrac{8}{\overline{AB}}= \dfrac{4}{14}\)
\(8 \cdot 14=4 \cdot{\overline{AB}}\)
\(\overline{AB}=\dfrac{8 \cdot 14}{4}\)
\(\boxed{\overline{AB}=28}\)
Solve for BC:
\(5 : \overline{BC} = 4:14\)
\(5 \cdot 14=4 \cdot \overline{BC}\)
\(\overline{BC}=\dfrac{5 \cdot 14}{4}\)
\(\boxed{\overline{BC}=17.5}\)
\(\hrulefill\)
Question 5Assuming the two figures are similar, their corresponding sides are in the same ratio. Therefore:
\(x:6=11:5\)
\(\dfrac{x}{6}=\dfrac{11}{5}\)
\(x=\dfrac{11 \cdot 6}{5}\)
\(x=\dfrac{66}{5}\)
\(\boxed{x=13.2}\)

What is the volume of this triangular pyramid
Answers
Answer:
The right triangular pyramid volume is given by the formula V = 1 3 × B × h , where B is the area of the triangular base and h is the height (the distance from the apex to the base).
Step-by-step explanation:
Answer:
192 cubic feet
Step-by-step explanation:
The volume V of a triangular pyramid is given by the formula:
V = (1/3) * base area * height
where base area is the area of the triangular base.
In this case, the triangular base has a length of 8 ft and a width of 8 ft, so it is a square with area:
base area = length * width = 8 ft * 8 ft = 64 sq ft
Substituting the given values into the formula, we get:
V = (1/3) * 64 sq ft * 9 ft
V = 192 cubic feet.
Therefore, the volume of the triangular pyramid is 192 cubic feet.

Answers
After solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.
What do we mean by mathematical operations?A mathematical function called an operation, also known as an "operand" or "argument," transforms zero or more input values into a precisely defined output value.The quantity of operands affects the operation's arity.The operations that are most frequently studied are unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, and binary operations (i.e., operations of arity 2), such as addition and multiplication.An operation of arity zero also referred to as a nullary operation, is a constant.The mixed product is an illustration of an operation of arity 3, also referred to as a ternary operation.So, the total value of money by 35 bills is $0, and $20 is $520.
Now, we know that: 20 × 18 = 360Similarly, we know that: 10 × 16 = 160Sum of 360 and 160: 360 + 160 = $520So, 185 bills of $20 and 16 bills of $10.Therefore, after solving some mathematical operations we can conclude that the cashier has 16 bills of $10 and 18 bills of $20.
