So b=-2 so you plug b in
l(-2)l + (-2)^3.
The absolute value of -2 is just 2 so now it is
2 + (-2)^3.
-2 * -2 is 4 but 4 * -2 is -8. So 2 + (-8) or 2 - 8 which comes to equal (-6) or negative six.
Answer:
The amplitude is 1/5
Step-by-step explanation:
Given
Required
Determine the amplitude
The general cosine function is:
Where
Compare and
So:
<h3>1.</h3>
The equation in point-slope form: y - y₁ = m(x - x₁)
slope: m = -2
point: (4, -5) ⇒ x₁ = 4, y₁ = -5
Therefore, the equation of the line in point-slope form:
<h3>
y + 5 = -2(x - 4)</h3>
<h3>2.</h3>
The equation in slope-intercept form: y = mx + b
Parallel lines has the same slope, so:
y = 4x + 2 ⇒ a = 4
If a line passes through the point <em>(x₁, y₁) </em>then the equation y<em>₁</em> = mx<em>₁</em> + b is true.
(4, 6) ⇒ x₁ = 4, y₁ = 6
So: 6 = 4·4 + b ⇒ b = -10
Therefore the equation:
<h3>
y = 4x - 10</h3>
<h3>3.</h3>
a = 3
(-1, 1) ⇒ x₁ = -1, y₁ = 1
So: 1 = 3·(-1) + b ⇒ b = 4
The equation:
<h3>
y = 3x + 4</h3>
<h3>4. </h3>
The product of slopes of perpendicular lines is -1.
2x - 7y = 1 ⇒ 7y = -2x + 1 ⇒ y = -²/₇x + ¹/₇
-²/₇×m = -1 ⇒ m = ⁷/₂
(0, -4) ⇒ x₁ = 0, y₁ = -4
-4 = ⁷/₂·0 + b ⇒ b = -4
The equation:
<h3>
y = ⁷/₂x - 4</h3>
So 6 people split 143.40. 143.40/6 = 23.90. Thats how much each person paid for the dinner. Add the 7.50 they paid for the movie and you would get 31.40$ total for each person. If this is right could I possibly have brainliest? Hope this helped!! :)
Answer:
41.6 m
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length ), then
s² = 108.16 ( take the square root of both sides )
s = 
= 10.4
Then
perimeter = 4s = 4 × 10.4 = 41.6 m
