5 ( x - 1) and 5x - 1 HELP
Answer:
Both of them are NOT equivalent.
Step-by-step explanation:
Use the distributive property to see if 5(x - 1) and 5x - 1 were equivalent.
5(x - 1)
= 5x - 5
This tells us 5(x - 1) is not equivalent to 5x - 1.
Which pair of triangles can be proven congruent by SAS?
Answer:
top choice
Step-by-step explanation:
For SAS, you need a side followed by an angle followed by another side of one triangle to be congruent to the corresponding parts of another triangle.
The top choice shows side-angle-side.
The middle choice shows angle-side-angle.
The bottom choice shows side-side-side.
Answer: top choice
find the area of the shaded region. geometry please help if your good at it. will mark brainlist
Area of shaded region = area of circle - area of segment
(where "segment" refers to the unshaded region)
Area of circle = π (11.1 m)² ≈ 387.08 m²
The area of the segment is equal to the area of the sector that contains it, less the area of an isosceles triangle:
Area of segment = area of sector - area of triangle
130° is 13/36 of a full revolution of 360°. This is to say, the area of the sector with the central angle of 130° has a total area equal to 13/36 of the total area of the circle, so
Area of sector = 13/36 π (11.1 m)² ≈ 139.78 m²
Use the law of cosines to find the length of the chord (the unknown side of the triangle, call it x) :
x ² = (11.1 m)² + (11.1 m)² - 2 (11.1 m)² cos(130°)
x ² ≈ 404.82 m²
x = 20.12 m
Call this length the base of the triangle. Use a trigonometric relation to determine the corresponding altitude/height, call it y. With a vertex angle of 130°, the two congruent base angles of the triangle each measure (180° - 130°)/2 = 25°, so
sin(25°) = y / (11.1 m)
y = (11.1 m) sin(25°)
y ≈ 4.69 m
Then
Area of triangle = xy/2 ≈ 1/2 (20.12 m) (4.69 m) ≈ 47.19 m²
so that
Area of segment ≈ 139.78 m² - 47.19 m² ≈ 92.59 m²
Finally,
Area of shaded region ≈ 387.08 m² - 92.59 m² ≈ 294.49 m²
Please help ASAP. I need someone to check my Geometry answer and explain why I am right or wrong. REAL ANSWERS ONLY. 20 PTS!
Answer:
you are right
Step-by-step explanation:
Use the law of law of cos
c^2=a^2+b^2﹣2abcos√angle
(2√13)^2=52=4+36-24cos(a)
cos(a) = -12/24 = -1/2
a = 120 degrees
so yes, you are right

find the exact value of sin a = 4/5, a lies in quadrant 2, and cos B = 2/5, B lies in quadrant 1 find cos(a-b)
Answer:
Cos(a - b) = 0.959
Step-by-step explanation:
We know that:
Sin(a) = 4/5
Such that a is on the first quadrant (between 0° and 90°)
then:
Sin(a) = 4/5
Asin(sin(a)) = Asin(4/5)
a = Asin(4/5) = 53.13°
And:
Cos(b) = 2/5
Then:
Acos(Cos(b)) = Acos(2/5)
b = Acos(2/5) = 36.67°
Then:
Cos(a - b)
where:
a = 53.13° and b = 36.67°
Then:
Cos(a - b) = Cos(53.13° - 36.67°) = 0.959

HELP HELP 100 POINTS!! Paola was given the equation y= -x + 3. Which of following is an equivalent representation of the equation.
a. f(x) = -x + 3
b. f(y) = x
c. y = -f(x) + 3
d. f(y) = -x + 3
i also need a explanation
Answer:
a. Is the answer..
Let's solve for y.
y=−x+3
Answer:
y = −x + 3 = y = −x + 3
Hence f(x) = -x + 3 is equivalent to y = −x + 3

Ten hamburger values meals cost $60.
Please help i can’t figure out the scale factor on these polygons
Answer: Scale of 2:1
Step-by-step explanation:
All the angles are the same. So its the same polygon just bigger.
Line DA multiplied by a factor of 2 will make is as long as Line ZW.
Line AB multiplied by 2 will also make it equal to Line WX
From that we can assume that Lines XY and YZ are equal to Lines BC and CD

Use a table of Laplace transforms to find the Inverse Laplace transform of
F(s)= [tex]\frac{3s+9}{s^2+9}[/tex]
f(t)=_____
Answer:
The inverse Laplace transform of [tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex] is [tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex].
Step-by-step explanation:
In this case, we should use the following direct and inverse Laplace Transforms:
[tex]F(s) = G(s) + H(s)[/tex] (1)
[tex]\mathcal{L}^{-1} \{\frac{s}{s^{2}+\omega^{2}} \} = \cos \omega t[/tex] (2)
[tex]\mathcal{L}^{-1}\{\frac{\omega}{s^{2}+\omega^{2}} \} = \sin \omega t[/tex] (3)
[tex]\mathcal\{L\}^{-1}\{c\cdot F(s)\} = c\cdot \mathcal\{L\}^{-1}\{F(s)\}[/tex] (4)
Then, we apply all these trasforms:
[tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex]
[tex]F(s) = 3\cdot \left(\frac{s}{s^{2}+9} \right)+3\cdot \left(\frac{3}{s^{2}+9} \right)[/tex]
[tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex]
The inverse Laplace transform of [tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex] is [tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex].

A parabola has its vertex at (-6, 5) and focus at (-6.25, 5). Which of the following is an equation for this parabola?
Answer:
Step-by-step explanation:
vertex and focus are horizontally aligned, so parabola is horizontal.
focal length p = distance between focus and vertex = 0.25
focus lies to the left of vertex, so the parabola opens to the left.
x = a(y-k)² + h,
vertex (h,k)
a = -1/(4p)
vertex (-6,5)
h = -6
k = 5
p = 0.25
a = -1/(4·0.25) = -1
x = -(y-5)² - 6
