In the figure, angle ABC and angle ADB are each right angles. Additionally, AC = 17.8 units and AD = 5 units. What is the length of segment DB?
Answer:
DB = 8
Step-by-step explanation:
Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is
\(\frac{DB}{DC}\) = \(\frac{AD}{BD}\) , substitute values
\(\frac{DB}{17.8-5}\) = \(\frac{5}{BD}\)
\(\frac{DB}{12.8}\) = \(\frac{5}{BD}\) ( cross- multiply )
DB² = 64 ( take the square root of both sides )
DB = \(\sqrt{64}\) = 8
The length of segment DB is 8 units.
From the given right triangle we can deduce the following;
triangle ABD and triangle DBC are similar triangleslength AC = 17.8 unitslength AD = 5 unitsFrom the corresponding triangle rules, we can calculate the length of DB by considering the following ratios;
\(\frac{DB}{DC} = \frac{AD}{DB} \\\\DB^2 = AD\times DC\\\\DB^2 = 5 \times (17.8-5)\\\\DB^2 = 5 \times 12.8\\\\DB^2 = 64\\\\DB = \sqrt{64} \\\\DB = 8 \ units\)
Thus, the length of segment DB is 8 units.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Step-by-step explanation:
As you can see, 16 and 32 are opposites of each other. So they can 'cross out'
16 times 2 is 32 so that is ok so far.
The next two numbers are 8 and 72.
For this to be proportional 8 times 2 has to equal 72, but it doesnt.
Therefore this is NOT proportional.

What are two different ways you could find the value of a? Explain these methods.
Answer:
Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.
(Root 15^2-9^2=12) (Root 12^2+16^2=20)
Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.
(Root 25^2-15^2=20)
Step-by-step explanation:
Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.
We have to find the value of ‘a’ using two different ways.
By the Pythagorean theorem,
By cross multiplication,
16(25) = a2
a2 = 400
Taking square root,
a = 20
Therefore, the length of the other side a = 20.
How do you find the value?
You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.
