Answer:
b = 148.5052112
Step-by-step explanation:
To find the value of b we will use the trigonometry functions
∵ The triangle is a right triangle
∵ The measure of one of its acute angles = 68°
∵ The length of the side opposite to the angle of measure 68° is b
∴ The opposite side = b
∵ The length of the side adjacent to the angle of measure 68° is 60
∴ The adjacent side = 60
∵ The function tan(x) = [tex]\frac{opposite}{adjacent}[/tex]
∴ tan(68°) = [tex]\frac{b}{60}[/tex]
→ Multiply both sides by 60 to cancel the denominator of the right side
∴ 60 × tan(68°) = b
∴ 148.5052112 = b
∴ b = 148.5052112
Answer:
b = 148.5052112

After 8 months, you have been able to save $937. You have the ability to save $130 per month. Build a model and write an explanation of the y- intercept. What is the rate of change?
Given:
After 8 months, you have been able to save $937.
You have the ability to save $130 per month.
To find:
The model for the situation and y-intercept and rate of change.
Solution:
Let y be the ability to saving after x months.
Ability to save in one month = $130
Ability to save in x months = $130x
So, total ability is
[tex]y=130x+b[/tex] ...(i)
where, b is initial savings.
After 8 months, you have been able to save $937. So, the point is (8,937).
Put x=8 and y=937 in (i),
[tex]937=130(8)+b[/tex]
[tex]937=1040+b[/tex]
[tex]937-1040=b[/tex]
[tex]-103=b[/tex]
So, the y-intercept is -103. Here, negative sign represents that we cannot able to save initially or we have loan or liabilities of $103.
Put b=-103 in (i).
[tex]y=130x+(-103)[/tex]
[tex]y=130x-103[/tex]
On comparing with slope intercept form, we get
Slope = 130 and y-intercept = -103
Therefore, the slope is 130 and y-intercept is -103.

The directrix of a parabola is y = 4. Its focus is (2,6).
What is the standard form of the parabola?
Answer:
Step-by-step explanation:
The standard form of parabola having vertex ( 2 , 5) is given by y = [tex]\frac{1}{4}[/tex] ( x - 2 )² + 5.
What is a parabola ?
A parabola is a plane curve that is produced when a point moves so that its distance from a given point equals its distance from a fixed line.
We know that , the standard form or general equation of a parabola is given by :
y = a ( x - h )² + k
where : vertex is (h, k) and focus ( h , k + p)
We know that here directrix is y = k - p and a is a = [tex]\frac{1}{4p}[/tex]
It is given that focus is (2 , 6).
From focus :
h = 2 and k + p = 6
whereas from directrix :
k - p = 4
Adding both
k + p = 4
k - p = 6
We get :
2k = 10
or
k = 5
So ,
p = 1
And vertex will be :
(h , k) = (2 , 5).
The vertical distance from vertex to directrix p = 1 :
y = a ( x - 2 )² + 5
here , a = [tex]\frac{1}{4p}[/tex] or a = 1/4
So , the standard form of given parabola will be :
y = [tex]\frac{1}{4}[/tex] ( x - 2 )² + 5
Therefore , the standard form of parabola having vertex ( 2 , 5) is given by y = [tex]\frac{1}{4}[/tex] ( x - 2 )² + 5.

where x = no. of years.
company A = company B28,000 + 3,000 (x) = 36,000 + 2000 (x)
3,000 (x) - 2,000 (x) = 36,000 - 28,000

WILL MAKE BRAINLIEST! Let sin 21 = 0.358. What is the value of x for cos x = 0.358
Answer:
The value of x is 69°
Step-by-step explanation:
In a right angle triangle, if m and n are the two acute angles on it, then
m + n = 90° sin(m) = cos(n)cos(m) = sin(n)That means if sin(m) = cos(n), then m + n = 90°
Let us use these facts to solve the question
∵ sin(21°) = 0.358
∵ cos(x°) = 0.358
→ That means sin(21°) = cos(x°)
∴ sin(21°) = cos(x°)
→ By using the facts above
∴ 21 + x = 90°
→ Subtract 21 from both sides
∵ 21 - 21 + x = 90 - 21
∴ x = 69°
∴ The value of x is 69°
