Find AC. Please help fast
Answer:
Step-by-step explanation:
AB/ED = AC/DF
15/18 = AC/20
5/6 = AC/20
Cross multipy
6AC = 5*20 = 100
so
AC = 100/6 = 16.7
Which transformation of AB will produce a line segment A'B' that is parallel to AB?
Options:
Rotation of 180° about point B
Rotation of 90° about point b
Reflection over the x-axis
Translation down 2 units
Answer:
Rotation of 180° about point B
Step-by-step explanation:
Considering coordinates of point B
Assume the coordinates of the line at point B is (x,y)
i.e. [tex]B = (x,y)[/tex]
First, we need to determine the slope at point B
Taking coordinates about the origin.
The slope of B is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,0)[/tex] --- origin
[tex](x_2,y_2) = (x,y)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{y - 0}{x - 0}[/tex]
[tex]m = \frac{y}{x}[/tex]
Taking the options one after the other:
Option A.
When rotated by 180°, the resulting coordinates of B would be
[tex]B' = (-x,-y)[/tex]
Taking the slope of B'
The slope of B is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,0)[/tex] --- origin
[tex](x_2,y_2) = (-x,-y)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-y - 0}{-x - 0}[/tex]
[tex]m = \frac{-y}{-x}[/tex]
[tex]m = \frac{y}{x}[/tex]
Notice that the slope of B and B' is the same;
[tex]m = \frac{y}{x}[/tex]
Hence:
Rotation of 180° about point B answers the question
There's no need to check for other options

Establish a relationship to determine the equivalent resistance R of a combination of three resistors having resistances R1, R2 and R3 connected in series. Calculate the equivalent resistance of the combination of three resistors of 2 Ω, 3 Ω and 6 Ω joined in parallel.
Answer:
Step-by-step explanation:
the resistors which connected in series
equivalent resistance = R1 +R2 + R
is the relationship between the resistors connected in series.
For parallel connection
R1 = 2ohm
R2 = 3ohm
R3 = 6ohm
for equivalent resistance (Rt)
1/Rt = 1/R1 + 1/R2 + 1/R3
1/Rt = 1/2 + 1/3 + 1/6
1/Rt = (3 + 2 + 1)/6 = 6/6 =1/1
Rt = 1 ohm
equivalent resistance = 1 ohm

Find the amount of simple interest earned for depositing the given principle in an account. if $3100
is invested at 5.5 % for 3 months
Answer:
$ 42.625 is the correct answer .Step-by-step explanation:
principal ( p ) = $3100
Rate ( R ) = 5.5 %
Time ( T ) = 3 months
( convert months into year)
= 3/12 year
Simple Interest ( I ) = ??
By using formula ,
simple Interest ( I) = PTR / 100
=$3100 × 5.5 % × 3/12 ÷ 100
= 3100 × 5.5 × 3 ÷ 100 × 12
= 51150 ÷ 1200
= 42.625

Enter the coordinates of the point
on the unit circle at the given angle.
240°
EXPLANATION:
To convert degrees to radians, multiply by π / 180 °
since a full circle is 360° or 2π radians.
240°⋅π / 180° radians
Cancel the common factor of 60
4 × π / 3 radians
Combine 4 and π / 3.
4π / 3 radians
HOPE ITS HELPS !!!!!
The coordinates of the points on unit circle at the given angle 240 degrees is[tex](\frac{-1}{2} ,\frac{-\sqrt{3} }{2} )[/tex]
The formula for calculating Radians is:
[tex]radians= (degrees)[/tex]×[tex]\frac{\pi }{180}[/tex]
Formula for calculating coordinates of point (x, y) on circle:x=rcosθ
y=rsinθ (where r is the radius of circle for unit circle r=1)
According to the question
we have
θ = 240 degrees and, r =1
so, 240 degrees = 240×[tex]\frac{\pi }{180}[/tex]
⇒240 degrees = [tex]\frac{4\pi }{3}[/tex] (in radians)
Therefore, the coordinates of the points on unit circle at angle [tex]\frac{4\pi }{3}[/tex] is calculated as
[tex]x=(1)cos\frac{4\pi }{3}[/tex] (for unit circle r=1)
[tex]x=\frac{-1}{2}[/tex]
And,
[tex]y=(1)sin\frac{4\pi }{3}[/tex] (for unit circle r=1)
[tex]y=\frac{-\sqrt{3} }{2}[/tex]
Hence, the coordinates of the point on unit circle at angle 240 degrees is [tex](\frac{-1}{2} ,\frac{-\sqrt{3} }{2} )[/tex]

I think you should start off by solving the function equal to the given growth.
[tex]f(m) = 5.98[/tex]
[tex]3(1.09) {}^{m} = 5.98[/tex]
[tex]1.09 {}^{m} = \frac{5.98}{3} [/tex]
[tex]1.09 {}^{m} = 1.9933[/tex]
[tex]m \times ln(1.09) = ln(1.9933) [/tex]
[tex]m = \frac{ ln(1.9933) }{ ln(1.09) } = 8 [/tex]
It is sufficient to plot the exponential growth over the domain m [0,8]
2)
The y-intercept in this case represents the growth achieved at the beginning when m=0.
Before the experiment started::
3)
I'm not really sure about this one,but i think it's supposed to be solved according to this eq,,
[tex]c = \frac{f(8) - f(2)}{8 - 2} [/tex]
Note that c is the average rate of change.
Find f(2) first by substituting 2 in f(m)
f(2)=3(1.09)²=3.5643
[tex]c = \frac{5.98 - 3.5643}{ 8 - 2} [/tex]
[tex]c = \frac{2.4157}{6} = 0.4026[/tex]
average growth=0.4026 cm/month

Sami's savings account earns 4% simple interest. If Sami starts with $500 in her account, how much money will she have in
her account after four years?
Answer:
$584.92928
Step-by-step explanation:
If Sami starts with $500 and earns 4% and she doesnt take away any money, the equation would be:
y=500(1.04)^x
y being dollars and x in years
if we replace x with 4, the answers come out to be 584.92928
Answer:
Step-by-step explanation:
First, we express the annual interest rate r, in decimal form. Since it is 4%, the interest rate is
r=4%=4100=0.04.
The principal P=500, so the future value is
A=P(1+rt)=500(1+(0.04)(4))=$580.

A rotating sprinkler head sprays water as far as 20 feet. The head is set to cover a central angle of 80 degrees. What area of grass will be watered?
A. 200/9 pi ft^2
B. 800/9 pi ft^2
C. 80/9 pi ft^2
D. 760/9 pi ft^2
Using the area of a circle, it is found that the area of the grass that will be watered is given by:
B. 800/9 pi ft^2
What is the area of a circle?The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex].
In this problem, a rotating sprinkler head sprays water as far as 20 feet, hence the radius is of r = 20 ft.
It covers a central angle of 80º, while an entire circle has 360º, hence the area of grass that will be watered corresponds to 80/360 = 2/9 of the area of the circle.
Hence the watered area in ft² is given by:
[tex]A = \frac{2}{9}\pi (20)^2 = \frac{800\pi}{9}[/tex]
Which means that option B is correct.

point b is between A and C. if AB =2x, BC =3x+1, and AC=21, find the length of BC
Step-by-step explanation:
We are here given that a point B is between A and C . Also ,
Value of AB = 2x Value of BC = 3x + 1 Value of AC = 21 .And we would like to calculate the length of BC . For figure refer to the attachment. From figure we can see that ,
[tex]\rm:\implies AC = AB + BC [/tex]
Substitute the respective values,
[tex]\rm:\implies 21 = 2x + 3x + 1[/tex]
Add like terms ,
[tex]\rm:\implies 21 = 5x +1 [/tex]
Subtract 1 on both sides,
[tex]\rm:\implies 21-1 = 5x [/tex]
Simplify,
[tex]\rm:\implies 20=5x [/tex]
Divide both sides by 5,
[tex]\rm:\implies \blue{ x = 4}[/tex]
Now consider ,
[tex]\rm:\implies BC = 3x+1 [/tex]
Plug in the value of x found above ,
[tex]\rm:\implies BC= 3(4)+1[/tex]
Simplify,
[tex]\rm:\implies BC = 12+1[/tex]
Add,
[tex]\rm:\implies \underline{\boxed{\blue{\rm{ \quad BC \quad =\quad 13\quad }}}}[/tex]
And we are done !
Answer:
+ BC = AC
x + 2x+1 = 22
3x +1 = 22
3x = 21
x = 7
AB = 7
BC = 2*7+1 = 14 + 1 = 15
