if [tex]cosA=\frac{2}{5}[/tex] and [tex]tanA\ \textless \ 0[/tex] then [tex]sin(2A)=?[/tex]
Please help
Absurd answers will not be tolerated
Answer:
[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(A)=\frac{2}{5}\text{ and } \tan(A)<0[/tex]
And we want to determine the value of:
[tex]\sin(2A)[/tex]
First, since cos(A) is positive and tan(A) is negative, this means that ∠A must be in QIV.
In QIV, cosine is positive, sine is negative, and tangent is also negative.
The given ratio tells us that the adjacent side to ∠A is 2, and the hypotenuse is 5.
Then by the Pythagorean Theorem, the opposite side will be given by:
[tex](2)^2+o^2=(5)^2[/tex]
Solve for the opposide side:
[tex]o=\sqrt{5^2-2^2}=\sqrt{21}[/tex]
So, with respect to ∠A, the adjacent side is 2, the opposite side is √(21), and the hypotenuse is 5.
Using the double-angle identity, we can rewrite our original expression as:
[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]
Using the above information, substitute in values. Remember that cosine is positive and that sine is negative:
[tex]\displaystyle \sin(2A)=2\Big(-\frac{\sqrt{21}}{5}\Big)\Big(\frac{2}{5}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2A)=\frac{-4\sqrt{21}}{25}[/tex]
Answer:
sin 2A=2sin Acos A
=2×2/5×√21/5=±4√21/25
Step-by-step explanation:
cos A=2/5
B/H=2/5
corresponding value we get
B=2
H=5
by using Pythagoras law
H²=P²+B²
5²=P²+2²
P²=25-4
p=√21
now
sin A=P/H=√21/5
now
sin 2A=2sin Acos A=2×2/5×√21/5=±4√21/25
21/82 as a percentage

Answer:
C
Step-by-step explanation:
Answer:
ok so its C bc 8 x 0.5 = 4 and so there are 4 long rectangles so multiply by 4 which is 16 bc 4 x 4 = 16 next find the area of the 2 squares 0.5 x 0.5 =0.25
multiply that by 2 because there are 2 squares which is 0.5 and so
16+0.5= 16.5 in²

$250 decreased by 17%
pls help
Answer:
$42.50
Step-by-step explanation:
250*0.17=42.5
cause %17 in decimal form is 0.17
Answer:
250 decreased by - 17% = $207.50
Explanation
Discount = Original Price x Discount %/100
Discount = 250 × 17/100
Discount = 250 x 0.17
You save = $42.50
Final Price = Original Price - Discount
Final Price = 250 - 42.5
Final Price = $207.50
Which of the following describes the transformation from Figure 1 to Figure 2?
9514 1404 393
Answer:
Rotation 90° CCW
Step-by-step explanation:
Note that Figure 1 has a small appendage off the larger rectangle. That appendage is pointing East (to the right).
In Figure 2, that same appendage is pointing North (up).
If you are facing East and you want to face North, you will find that you need to turn 90° in the counterclockwise direction. That is the transformation that was done here:
rotation 90° CCW about the origin
Answer:
A rotation of 90° counter-clockwise around the origin

If x varies as y and if x=20 when y=9 , find x when y=18
Answer:1/2 y
Step-by-step explanation:
We can solve this using ration reasoning:
x
2
x
1
=
y
2
y
1
Explanation:
If
x
varies directly with
y
(written
x
∝
y
), then doubling
y
means doubling
x
, so the rations of final values and initial values will be the same:
x
2
x
1
=
y
2
y
1
In this case,
x
2
9
=
24
18
x
2
=
9
⋅
24
18
=
12
Or, intuitively, if
x
∝
y
and
x
=
9
when
y
=
18
, we can conclude that
x
=
1
2
y
and
1
2
of 24 is 12.

Need help plz. Don't answer for points or you will be reported!
Step-by-step explanation:
13.
Supplementary angles = 180º (theorem)
Set <ABD + <DBC = 180º
2x + (x+24) = 180º
add like terms = 3x+24=180
3x=156
x = 52
now plug in x for both angles
<ABD = 2(52) = 104
<DBC = 52+24 = 76
14.
complementary angles = 90º (theorem)
set <EFG + <GFH = 90º
y-32 + y = 90
2y - 32 = 90 : combine like terms
2y = 122
y = 61
now plug in y for both angles
<EFG = 61-32 = 29
<GFH = 61
15.
Vertical angles are equal to each other (theorem)
<PQR = <TRS
38 = 5w-7
45 = 5w
w = 9
plug into <TRS
<TRS = 5(9) - 7 = 38
(Also since you know that <PRQ is 38 and that the measure has to be the same for both angles, it can be assumed without algebra that <TRS would be 38º)

Alex invests £3045 into an account that pays 2.25% compound interest per year.
Work out how much Alex will have in the account after 16 years.
Thanks :)
Money in Alex's account after 16 years = [tex]\boxed{\bold{\color{plum}£4347.11}}[/tex]
○=> Steps to derive correct answer :Money invested by Alex = £3045
Percentage of compound interest per annum = 2.25%
We know that :
[tex]\tt \: \color{hotpink}A \color{plum} = P {(1 + \frac{r}{n} )}^{nt} [/tex]
In this case :
Principal = £3045
Rate = 2.25% = 0.0025
Number of times interest is compounded per year = 1
Time = 16 years
Which means :
Money Alex will have in the account after 16 years :
[tex] = \tt3045 ({1 + \frac{ 0.0025}{1} })^{16} [/tex]
[tex] \color{plum}= \tt £4347.11[/tex]
Therefore, the money in Alex's account after 16 years = £4347.11
The diameter of a circle is 19 in. Find its circumference in terms of \piπ.
Answer:
Circumference = 2pi(radius)
C = 2(pi)(9.5)
C = 19pi
The answer is 19pi.
Let me know if this helps!
Answer:
The circumference is 59.6903
Step-by-step explanation:
In order to find the circumference, use the equation C=2πr
Radius is essentially half of the diameter, so 9.5 is our radius
C=2π(9.5)
C≈59.6903
