Answer:
y = -3x - 8
Step-by-step explanation:
[tex]y =\frac{1}{3}x+ 2[/tex]
Here slope m = (1/3)
Slope of the perpendicular line = [tex]\frac{-1}{m}[/tex] = -1 ÷ [tex]\frac{1}{3} = -1 *\frac{3}{1}= - 3[/tex]
Slope m1 = -3 and (-3 ,1)
Equation of line:
y -y1 = m(x -x1)
y - 1 = -3(x - [-3])
y - 1 = -3(x + 3)
y - 1 = (-3) *x + 3*(-3)
y - 1 = -3x - 9
y = -3x -9 +1
y = -3x - 8
Answer:
y = - 3x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x + 2 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 3, 1 ) into the partial equation
1 = 9 + c ⇒ c = 1 - 9 = - 8
y = - 3x - 8 ← equation of perpendicular line

295.6 divided by 10 with the power of 2
Answer:
2.956
Step-by-step explanation:
[tex]\frac{295.6}{10^2}[/tex]
= [tex]\frac{295.6}{100}[/tex]
= 2.956
Answer:
873.7936
Step-by-step explanation:
295.6 divided by 10 is
29.56.
This can be easily done by moving the decimal up one place to the left. For 29.56 to the power of 2 is really just 29.56 * 29.56
29.56 * 29.56 is
873.7936.

Answer:
y= 37.5
Step-by-step explanation:
x = 30°
180-30= 150
4x=150
x = 37.5
Answer:
Y = 40
Step-by-step explanation:
I do not understand that language but if it is asking what Y is equal to when x is equal to 30 degrees and EFG is a straight line.
1. 3Y + 2X = 180 (Straight angle)
2. X = 30 (given)
3. therefore 2X = 2x30
= 60
4. Therefore 3Y + 60 = 180
5. 3Y = 180 - 60
6. 3Y = 120
7. Y = 120/3
8. Y = 40

(g + 4) - 3g = 1 + g
(g + 4) - 3g = 1 + g
or, g + 4 - 3g = 1 + g
or, -2g + 4 = 1 + g
or, -2g - g = 1 - 4
or, -3g = -3
or, g = -3/-3
or, g = 1
The value of g is 1.
Find the area. Round to the nearest tenth.
Answer:
Step-by-step explanation:
The area of a triangle is
[tex]A=\frac{1}{2}bh[/tex] and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:
[tex]6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}[/tex]
That's the height that we will sub into the area formula:
[tex]A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8[/tex]

What is the inverse of the function f(x)=1/4x-12?
a. h(x)=48x-4
b. h(x)=48x+4
c. h(x)=4x-48
d. h(x)=4x+48
Answer:
d. h(x) = 4x + 48
Step-by-step explanation:
[tex]f(x) = \frac{1}{4} x - 12[/tex]
[tex]y = \frac{1}{4} x - 12[/tex]
[tex]x = \frac{1}{4} y - 12[/tex]
[tex] \frac{1}{4} y - 12 = x = 4( \frac{1}{4} y - 12) = 4x[/tex]
[tex]4 \times \frac{1}{4} y - 4 \times 12 = 4x[/tex]
[tex]y - 48 = 4x[/tex]
[tex]y = 4x + 48[/tex]
[tex]\boxed{\green{= h(x) = 4x + 48}}[/tex]
Here is a recursive definition for a sequence f: f(0) = 19, f(n) = f(n − 1) – 6 for
n? 1. The definition for the nth term is f(n) = 19 - 6. n for n > 0.
a. Explain how you know that these definitions represent the same sequence.
b. Select a definition to calculate f(20), and explain why you chose it.
(From Unit 1, Lesson 8.)
7. An arithmetic sequence j starts 20, 16, ... Explain how you would calculate the value
of the 500th term.
(From Unit 1, Lesson 8.)
An arithmetic progression is a sequence that has a common difference between consecutive terms.
[tex]f(n) = 19 -6n[/tex] and [tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex] represent the same sequenceThe definition I will choose for f(20) is: [tex]f(20) = 19 - 6 \times 20[/tex].The 500th term is -1976.Question 6:
The recursive function is given as:
[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex] for [tex]n \ge 1[/tex]
The definition of nth term is given as:
[tex]f(n) = 19 - 6n[/tex] for [tex]n > 0[/tex]
A proof that the functions represent the same sequence is as follows:
Set [tex]n=1[/tex] in
[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex]
[tex]f(1) = f(1 -1) - 6 = f(0) - 6[/tex]
[tex]f(1) = 19 - 6 = 13[/tex]
Set [tex]n = 2[/tex]
[tex]f(2) = f(2 -1) - 6 = f(1) - 6[/tex]
[tex]f(2) = 13 - 6 = 7[/tex]
Set [tex]n = 3[/tex]
[tex]f(3) = f(3 -1) - 6 = f(2) - 6[/tex]
[tex]f(3) = 7 - 6 = 1[/tex]
Write out the equations
[tex]f(1) = 19 - 6 = 13[/tex]
[tex]f(2) = 13 - 6 = 7[/tex]
[tex]f(3) = 7 - 6 = 1[/tex]
Rewrite as:
[tex]f(1) = 19 - 6 = 13[/tex]
[tex]f(2) = 19 - 6 - 6 = 7[/tex]
[tex]f(3) = 19 - 6 - 6 -6= 1[/tex]
Rewrite again as:
[tex]f(1) = 19 -6\times 1 = 13[/tex]
[tex]f(2) = 19 -6\times 2 = 7[/tex]
[tex]f(3) = 19 -6\times 3 = 1[/tex]
Replace the numbers in brackets with n
[tex]f(n) = 19 -6\times n[/tex]
[tex]f(n) = 19 -6n[/tex]
Hence, it is proved that
[tex]f(n) = 19 -6n[/tex] and
[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex] represents the same sequence
The definition I will choose for f(20) is:
[tex]f(20) = 19 - 6 \times 20[/tex]
This is gotten from [tex]f(n) = 19 -6n[/tex].
I choose the definition because it is faster to calculate f(20) directly, than using recursion
Question 7:
Given that:
[tex]T_1 = 20[/tex]
[tex]T_2 = 16[/tex]
First, we calculate the common difference
[tex]d = T_2 - T_1[/tex]
[tex]d = 16 - 20 =-4[/tex]
The 500th term is then calculated using the nth term of an arithmetic progression formula.
[tex]T_n = T_1 + (n - 1) \times d[/tex]
So, we have:
[tex]T_{500} = 20+ (500 - 1) \times -4[/tex]
[tex]T_{500} = 20+ 499 \times -4[/tex]
[tex]T_{500} = 20 -1996[/tex]
[tex]T_{500} = -1976[/tex]
Hence, the 500th term is -1976.
