Step-by-step explanation:
by using pythagoras theorem
h² = p² + b²
13² = 5² + b ²
b = √194
b = 13.93
now
tanФ = p/b
Ф = tan¬1( 5 / 13.93)
Ф = 19.80 °

Answer:
a) 16-x=x+4
add x to both sides
16=2x+4
subtract 4 from both sides
12=2x
divide both sides by 2
x=6
b) (8-x)-5=2
add 5 to both sides
8-x=7
add x to both sides
8=7+x
subtract 7 from both sides
x=1
c) 4+x=x+4
subtract 4 from both sides
x=x
x belongs to all real numbers.

Simone paid $14 for an initial year's subscription to a magazine. The renewal rate is $6 per year. This situation can be represented by the equation y = 6x + 14, where x represents the number of years the subscription is renewed and y represents the total cost, in dollars.
Answers
Answer:
12
Step-by-step explanation:
This is easy. Select different values for x to find y values.
For example, let x = 0.
y = 8x + 12
y = 8(0) + 12
y = 0 + 12
y = 12
On your table, you have x = 0 and y = 12.
Do the same using other values of x.

In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line L with center A and a scale factor of 3 will produce a new through point C’, the image of point C with coordinates
Answers
Answer:
Step-by-step explanation:
Dilation of a line about a point not on the line shifts the line but leaves the slope intact .
New line slope will be -2
As both A and C lie on a horizontal line y = 2, C' will also lie on the same line
The distance between A and C is 0 - 2 = -2
a scale factor of 3 means C' is -2(3) = -6 units left of A
C' = (2 - 6, 2) = (-4. 2)

When a whole number is multiplied by 10 to the power of 4 how does the placement of the decimal point change
Answers
9514 1404 393
Answer:
The decimal point moves 4 places to the right
Step-by-step explanation:
Take a simple case using the whole number 3.
3. — whole number we're starting with
3.×10^4 = 3.×10,000 = 30,000. — multiplied by 10^4
The decimal point moves 4 places to the right.
_____
Additional comment
Multiplying be a positive power of 10 moves the decimal point a number of places equal to that power. Effectively, the number of zeros added on the right is equal to the power of 10. Above, you will notice multiplying by 10^4 added 4 zeros to the right of the number.

y=−4x−3 y=−2x+1 ( Ignore this part i had to write it)
Answers
Answer:
Solve equation [2] for the variable y
[2] y = -2x + 1
// Plug this in for variable y in equation [1]
[1] (-2x+1) + 4x = -3
[1] 2x = -4
// Solve equation [1] for the variable x
[1] 2x = - 4
[1] x = - 2
// By now we know this much :
y = -2x+1
x = -2
// Use the x value to solve for y
y = -2(-2)+1 = 5
Solution :
{y,x} = {5,-2}
