Angle ABC and angle CBD are complementary. What is the value of x? Record your answer as a whole number.
No links please please please.
Answers
Answer:
x=31
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
So, 2x+28=90.
To solve:
1. Subtract 28 from both sides
2x=90-28
2x=62
2. Divide both sides by 2
x=62/2
x=31

[tex]36\ feet[/tex]
Step-by-step explanation:
Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,
[tex](height):(shadow)[/tex]
As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,
[tex]6:1.7[/tex]
It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).
[tex]6:1.7=x:10.2[/tex]
Cross products,

write the equation of an exponential function that passes through the points (2,48) and (5,750).
Answers
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x
The equation of an exponential function will be y = 7.68 × 2.5ˣ.
What is equation of line?
The equation of line with slope m and passes through the point (x₁, y₁) is calculated as;
y - y₁ = m (x - x₁)
Given that;
An exponential function passes through the points (2, 48) and (5, 750).
Now, The exponential function is;
y = abˣ
Where, a and b are unknowns.
Hence, For the point (2, 48), we get the equation;
48 = ab² .. (i)
And, For the point (5, 750), we get;
750 = ab⁵ .... (ii)
Solve the equation (i) for value of a, we get;
48 = ab²
a = 48/b²
Substitute in equation (ii);
750 = ab⁵
750 = (48/b²) b⁵
750 = 48 b³
b³ = 750/48
Take cube root both side;
b = 5/2
Hence, a = 48/b² = 48/(5/2)²
a = 48 × 4 / 25
a = 7.68
Thus, After substitute the value of a and b we get the exponential equation as;
y = 7.68 × 2.5ˣ
Therefore, The equation of an exponential function will be,
⇒ y = 7.68 × 2.5ˣ.

The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answers
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

Find mMK................
Answers
Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees

What is Factorizing?Brackets should be expanded in the following ways to factorize an expression
For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket
For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = x² + x - 56
On factorizing the equation , we get
A = x² + 8x - 7x - 56
8x - 7x = 1
So , A = ( x - 7 ) ( x + 8 )
Hence , the expression is A = ( x - 7 ) ( x + 8 )
