G is a trigonometric function of the form g(x)=a sin(bx+c)+d The function intersects its midline at (-1,6) and has a minimum point at (-3.5,3). Find the formula for g(x). Give an exact expression.
Answer:
g(x) = 3*sin((-15/4)*pi*x + (-15/4)*pi) + 6
Step-by-step explanation:
The function has the form:
g(x) = a*sin(b*x + c) + d
We know that:
The midline is at (-1, 6)
The midline is the value of g(x) when the sin(x) part is equal to zero
Then the midline is y = 6 = d
g(x) = a*sin(b*x + c) + 6
And from this we also know that:
sin(b*-1 + c) = 0,
We also know that the minimum is at (-3.5, 3)
The minimum is the y-value when the sin(x) part is equal to -1
Then
sin(b*-3.5 + c) = -1
And:
g(-3.5) = 3 = a*(-1) + 6
3 = -a + 6
a = -3 + 6 = 3
The equation is something like:
g(x) = 3*sin(b*x + c) + 6
To find the values of b and c, we need to use the two remaining equations:
sin(b*-3.5 + c) = -1
sin(b*-1 + c) = 0
We also know that:
Sin(0 ) = 0
sin( (3/2)*pi) = -1
where pi = 3.14
Then we can just write:
b*-1 + c = 0
b*-3.5 + c = (3/2)*pi
From the first one, we get:
-b + c = 0
c = b
Replacing that on the other equation we get:
c*-3.5 + c = (3/2)*pi
c*(-3.5 + 1) = (3/2)*pi
c*(-2.5) = (3/2)*pi
c = (3/2)*pi/(-2.5)
and:
-2.5 = -5/2
c = (3/2)*(-5/2)*pi = (-15/4)*pi
Then the equation becomes:
g(x) = 3*sin((-15/4)*pi*x + (-15/4)*pi) + 6
The trigonometric function equation becomes [tex]g(x)=3 sin(-1.88x-1.88)+6[/tex]
The function has the form:
[tex]g(x)=a sin(bx+c)+d[/tex]
The midline is at (-1, 6)
So, the midline is y = 6 = d
[tex]g(x)=a sin(bx+c)+6[/tex]
We know that the midline is the value of g(x) when the sin(x) part is equal to zero
Given that The function intersects its midline at (-1,6) and has a minimum point at (-3.5,3).
[tex]sin(-1*b + c) = 0,[/tex]
The minimum is the y-value when the sin(x) part is equal to -1
[tex]sin(-3.5*b + c) = -1[/tex]
Since, [tex]g(-3.5) = 3 = a*(-1) + 6[/tex]
[tex]a = -3 + 6 = 3[/tex]
Now equation become,
[tex]g(x) = 3*sin(b*x + c) + 6[/tex]
To find the values of b and c, we need to use the two remaining equations:
[tex]sin(-3.5b + c) = -1=sin( (3/2)* \pi)\\\\ -3.5b + c = (3/2)* \pi[/tex]
[tex]sin(-1b + c) = 0=sin(0)\\\\-b+c=0\\\\b=c[/tex]
Substituting b = c in above equation and [tex]\pi=3.14[/tex]
We get,
[tex]-3.5c + c = (3/2)*\pi\\\\-2.5c=4.71\\\\c=-1.88[/tex]
also [tex]b=-1.88[/tex]
Therefore, equation becomes [tex]g(x)=3 sin(-1.88x-1.88)+6[/tex]

Answer:
$223.21
Step-by-step explanation:
Last year the amount of taxes was x, an unknown amount. That was 100% of last year's tax cost.
This year, taxes went up by 12%, so this year the taxes are 112% of what they were last year. This year the taxes were 112% of x, and they were $250.
112% of x = 250
1.12x = 250
x = 250/1.12
x = 223.21

Answer:
538,3m^2
Step-by-step explanation:
first of all, I find it really disturbing to use 3,14 as pi but I'll try my best.
1) Determine the area of the rectangle;
h.b= area of a rectangle
so here
15m.30m = 450 m^2
the area of the circle = pi.r^2
so here
7,5m^2.3,14 = 176,625m^2
but we only need the half of it so 176,625m^2/2 = 88,3125m^2 ~ 88,3m^2
then we must sum them all up;
88,3m^2 + 450m^2 = 538,3m^2

Write the equation in standard form for the circle with center (-7,0) and radius 4 7
Answer:
x² + y² - 8x -14y - 105 = 0
Step-by-step explanation:
The centre of the circle is (-7,0) and the radius is (4,7) . Firstly let's find the radius using Distance formula .
=> D = √{ (-7-4)²+(0-7)²}
=> D = √ 11² + 7²
=> D = √ 121 +49
=> D = √170
Now using the standard equation of circle ⭕ ,
=> ( x - h)²+(y-k)² = r²
=> ( x - 4)²+(y-7)²= (√170)²
=> x² + 16 -8x + y² + 49 -14y = 170
=> x² + y² -8x -14y = 170 -65
=> x² + y² - 8x -14y - 105 = 0
• Hence the equation of circle is x² + y² - 8x -14y - 105 = 0 .The circumference of a circle is 15 centimeters. What is the diameter? Round to the nearest hundredths place.
Answer:
4.77
Step-by-step explanation:
because Circumference can be found with this equation
C = 2piR
we need to plug in 15 for Circumference and solve for its radius or R.
15 = 2piR
15/2pi = R
but we need diameter which is 2R so we just need to multiply the answer by 2.
15/2pi × 2 = Diameter
15/pi = D

Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that [tex]cos(x)=\frac{28}{39}[/tex]
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side
[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1

QUESTION:
What is mBDG?
Answer:
242
Step-by-step explanation:
Circles have a total of 360°
mDBG does not include mBA or mGA
This means that mDBG = 360 - ( mBA + mGA )
mBA = 28° ( this is given )
mGA = 90° ( this is also given; it's indicated by the right angle )
Thus, mDBG = 360 - ( 28 + 90 )
28 + 90 = 118
mDBG = 360 - 118
360 - 118 = 242
Hence, mDBG = 242

a circular plate has circumference 24.5 inches. what is the area of this plate? use 3.14 for pi.
Answer:
The area of the plate is 47.78
Step-by-step explanation:
Given:
Circumference of a circular plate = 24.5 inches.
To FInd:
Area of the circular plate
Solution:
By the formula of circumference
Circumference of a circular plate = 2πr
Where 'r' = radius of the plate
24.5 = 2[tex]\pi r[/tex]
r = [tex]\frac{24.5}{3.14 * 2}[/tex] [Since π = 3.14]
r = 3.90 inches
We know the formula of a circular plate is,
Area = πr²
Therefore, A = (3.14)(3.90)²
A = 47.79 square inches
Therefore, area of the circular plate is 47.79 inches.
