Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?
Answers
Answer:
\(BD = 14\ in\)
\(CD = 28\ in\)
Step-by-step explanation:
Given
CB = 14in
B as midpoint
Required
Determine CD and BD
Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:
\(CB = BD\)
\(CD = CB + BD\)
Reorder the first equation
\(BD = CB\)
Substitute 14 for CB
\(BD = 14\ in\)
Taking the second equation into consideration
\(CD = CB + BD\)
\(CD = 14 + 14\)
\(CD = 28\ in\)

The length AC in the kite is 8.7 cm.
How to find the side AC in the kite?A kite is a quadrilateral that has two pairs of consecutive equal sides and
perpendicular diagonals. Therefore, let's find the length AC in the kite.
Hence, using Pythagoras's theorem, let's find CE.
Therefore,
7² - 4² = CE²
CE = √49 - 16
CE = √33
CE = √33
Let's find AE as follows:
5²- 4² = AE²
AE = √25 - 16
AE = √9
AE = 3 units
Therefore,
AC = √33 + 3
AC = 5.74456264654 + 3
AC = 8.74456264654
AC = 8.7 units

Find the circumference of a circle with a radius of 15 centimeters. Round your answer to the nearest centimeter
Answers
Answer:
94 cm
Step-by-step explanation:
The formula for finding the circumference of a circle is;
Circumference = 2πr
where π = \(\frac{22}{7}\) or 3.14 and
r = radius
Here radius is 15 cm so;
Circumference = \(2 * \frac{22}{7} * 15\)
= \(\frac{660}{7}\)cm
= 94.28cm
= 94 cm ( rounded to the nearest centimetre )

The polynomial expression that represents the perimeter is (3x^3 +3x -148)ft and the value is 182ft
what is a polynomial?Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.
Perimeter of the triangle is the sum of the sides of the triangle which is = 2x^2 -120 + x^2 -5x +8x -28
Perimeter = (3x^2 +3x -148)ft
when x = 10
Perimeter = 3(10)^2 +3(10) -148 = 182ft

Despite having developed a reputation as a good cook, I'm really not one. What I am is a really good recipe follower. I put my trust in real chefs whose recipes are posted here on Recipe Masters. Turns out, though, my trust was misplaced. Sadly, my weekly supper club dinner that featured a Recipe Masters recipe for meatball sub casserole turned into a pizza delivery night. If after reading this review, any of my fellow Recipe Masters subscribers are still set on trying this casserole recipe, here is my advice: Stop after the first step, when the sauce turns into an un-stirrable glob. Don't do as I did and continue on, believing things will improve. They won't. Following this recipe is a recipe for disaster. My advice for Recipe Masters is to ensure that recipes posted here are "tried and true," as advertised. We subscribers pay a fee for access to "top-notch, no-fail recipes." If we lose faith in your recipes, we might just turn to the free recipe sites all over the internet.

Answers
The author of the review is disappointed with the meatball sub casserole recipe posted on Recipe Masters, which did not turn out well despite following the recipe.

"What is Limit of g (x) as x approaches 1, if it exists?"
Answers
The limit doesn't exist (DNE).
Follow the pattern in the table. You have g (0.9) = 7, g (0.99) = 700, g (0.999) = 70,000 and so on. For every 10% increase in the value of x, the value of g(x) increases by a factor of 100. So as x gets closer to 1 (that is, as you add more 9s after the decimal point to x), g(x) will continue to increase by several magnitudes. The same thing effectively happens from the other side.

Answers
The evaluation of the statements with regards to the graph of a function are;
The graph of non-vertical straight line is always a function, but the graph of a function is not always a straight line is true.What is a function?A function maps an input value to an output based on a definition or rule.
First part of the statement;
The graph of a non-vertical straight line has a range of values for the slope, m, of 0 ≤ m < ∞
The equation of a straight line function is of the form; y = m·x + c
Therefore;
The graph of a non-vertical straight line can be represented by the equation, y = m·x + c, where y has possible values of; -∞ < y < ∞, which indicates that as x increases or decreases, y increases (or decreases), such that each value of x maps unto only one value of y, which indicates that the graph is a function. The statement is therefore true.
Second part of the statement.
The graph of the quadratic function; y = a·x² + b·x + c has a shape of a parabola, therefore, the statement, the graph of a function is not always a straight line is true also.

Fiona adds 3/4 pound of fertilizer for every 12 pound of peat moss what is the constant of proportionality for the relationship between the weight of the fertilizer in the weight of the Peat moss
Answers
The constant of proportionality for the relationship between the weight of the fertilizer in the weight of the Peat moss is c = 16p.
What is constant of proportionality?Firstly, there is proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant. The constant k is called constant of proportionality. The proportional relationship between x and y can be written symbolically as \(x \propto y\)
That middle sign is called sign of proportionality.
We have been given that Fiona adds 3/4 pound of fertilizer for every 12 pound of peat moss.
WE are asked the constant of proportionality for the relationship between the weight of the fertilizer in the weight of the Peat moss.
Therefore, The amount of fertilizer is proportional to the amount of peat moss will gives;
Fiona adds 3/4 of fertilizer for every 12 of peat moss.
p : c = 3/4 : 12
p/c = 3/(4 x 12)
p/c = 1/16
Hence, the constant of proportionality for the relationship between the weight of the fertilizer in the weight of the Peat moss is c = 16p.

Answers
Answer:
b = -20
Step-by-step explanation:
Let's start by finding the slope of the line.
\(Slope=\frac{y_2-y_1}{x_2-x_1}\)
Origin: (0, 0)
We can use (0, 0) and (3, 5) to find the slope:
\(Slope=\frac{5-0}{3-0}=\frac{5}{3}\)
Then, we can plug this into the equation for slope to find the value of b (the slope has to be the same, since they're on the same line)
\(Slope=\frac{y_2-y_1}{x_2-x_1}\)
\(\frac{5}{3}=\frac{b-5}{-12-3}\\\frac{5}{3}=\frac{b-5}{-15}\\\text{Multiply both sides by -15}\\\frac{5}{3}(-15)=b-5\\\frac{-75}{3}=b-5\\-25=b-5\\\text{Add 5 to both sides}\\b=-20\)
