Find the equation of the straight line which is perpendicular to the straight line 3x+4y=12 such that perpendicular distance from the origin is equal to the perpendicular distance from (3,2) on the given line
Answers
Answer:
3y-4x = -6Step-by-step explanation:
First get the slope of the given line;
Given the equation of the line 3x+4y=12
Rewrite in standard form y = mx+c where m is the slope;
3x+4y=12
4y = -3x + 12
y = -3x/4 + 12/4
y = -3x/4 + 3
Hence the slope of the given line is -3/4
Since the required line is perpendicular to this line, the slope of the required line will be M = -1/(-3/4) = 4/3
Get the equation:
Substitute M = 4/3 and the point (3,2) into the point slope equation of a line as shown;
y-y0 = m(x-x0)
y - 2 = 4/3(x-3)
Cross multiply
3(y-2) = 4(x-3)
3y - 6 = 4x - 12
3y - 4x = -12 + 6
3y-4x = -6
Hence the required equation of the line is 3y-4x = -6

Betty is three times as old as her son now. In 12 years, Betty's age will be three years less than twice her son's age. How old is Betty's son now?
Answers
Answer:
Betty is 27. Her son is 9.
Step-by-step explanation:
We will use b to represent Betty's age. We will use s to represent her son's age.
This year:
b = 3s
In 12 years' time:
b + 12 = 2(s + 12) - 3
b + 12 = 2s + 24 - 3
b + 12 = 2s + 21
b = 2s + 9
We know that b = 3s, so we can substitute this value into our equation.
3s = 2s + 9
s = 9
b = 3 x 9
b = 27

c. 1-cos2(x)

Answers
Answer:
It's d
Step-by-step explanation:
(1+cos(x))(sin(x))
The trigonometric expression (1+cos(x))2(tan(x/2)) is equivalent to (1+cos(x))(sin(x)) option (d) is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The trigonometric expression is:
= (1+cos(x))²(tan(x/2))
As we know,
1 + cos(x) = 2cos²(x/2)
Use the above trigonometric identity:
= (2cos²(x/2))²(tan(x/2))
= 2 cos⁴(x/2) sin(x/2)/cos(x/2)
= 2 sin(x/2) cos³(x/2)
2sin A cos B = sin2A
Use the above trigonometric identity and after simplification we get:
= (1+cos(x))(sin(x))
The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Thus, the trigonometric expression (1+cos(x))2(tan(x/2)) is equivalent to (1+cos(x))(sin(x)) option (d) is correct.

Step-by-step explanation:
Given
6 - x = 4(5 + x) - 4 ← distribute and simplify right side
6 - x = 20 + 4x - 4
6 - x = 16 + 4x ( subtract 4x from both sides )
6 - 5x = 16 ( subtract 6 from both sides )
- 5x = 10 ( divide both sides by - 5 )
x = - 2

7. You are ordering sweaters from American Eagle. Each sweater costs $25. They also charge a shipping fee of $7. You spent. $132 How many sweaters?
Answers
Answer:
Step-by-step explanation:
Alright, after reading this problem, let’s highlight some key points. Each sweater costs $25, we can write that down as 25x because will represent the amount of sweaters we buy. But we have a shipping fee of $7, so we will +7 to our highlights. And the total money spent was $132.
So far, we have: 25x + 7 = 132
Let’s subtract the 7 from the 132. Now we have: 25x = 125
Then we can divide by 25 on each side, and get x by itself.
X = 5 sweaters.
BONUS: Let’s replace 5 for our x to prove our answer
25(5) + 7 = 132 >>> 125 + 7 = 132 >>> 132 = 132 :D
There you go!! We buy 5 sweaters from American Eagle..!

The following steps to solve equation given by join are shown below including the property of numbers applied for each reasons:
4(2a + 3) = -3(a - 1) + 31 - 11a ----› Given
Apply the distributive property to open the parentheses
4*2a + 4*3 = -3*a -3*-1 + 31 - 11a
8a + 12 = -3a + 3 + 31 - 11a ----› Distributive property
Combine like terms together
8a + 12 = 3 + 31 -3a - 11a
8a + 12 = 34 - 14a ---› Combining like terms
Add 14a to both sides
8a + 12 + 14a = 34 - 14a + 14a
22a + 12 = 34 ----› Addition property
Subtract 12 from both sides
22a + 12 - 12 = 34 - 12
22a = 22 ----› subtraction property of equality
Divide both sides by 22
22a/22 = 22/22
a = 1 ----› Division property of Equality

If b=24 and c=10 what is for the missing side a= ? by Use the Pythagorean Theorem to find
Answers
Answer:
a = 21.82 if and only if b=10 and c=24
if you meant b=24 c=10
there can't be such a triangle because the hypotenuse is the longest side
Step-by-step explanation:
[tex]a^2+b^2=c^2\\\\a=?\\\\b=24\\\\c=10\\\\\\a^2+(24)^2=(10)^2\\\\a^2=(10)^2-(24)^2\\\\a^2=(10-24)(10+24)\\\\a^2=-14(34)[/tex]
which doesn't work because something squared can't be a negative
if you meant
c=24 and b=10
[tex]a^2+(10)^2=(24)^2\\\\a^2=(24)^2-(10)^2\\\\a^2=(24-10)(24+10)\\\\a^2=(14)(34)\\\\a\approx 21.82[/tex]
9514 1404 393
Answer:
a = 26 or 21.82
Step-by-step explanation:
If 'a' is the hypotenuse, then ...
a² = b² +c²
a² = 24² +10² = 576 +100 = 676
a = √676 = 26 . . . if 'a' is the hypotenuse
__
If 'a' is the long side, then ...
b² = c² + a²
b² -c² = a² = 24² -10² = 576 -100 = 476
a = √476 ≈ 21.82 . . . if 'a' is the long leg

The diagonals of rhombus ABCD intersect at E. Given that m∠CAD=20° and CE=4, find the m∠CDA.
Answers
Answer:
< CDA = 140 degrees
Step-by-step explanation:
For a rhombus, the sum of the interior angles is 360 degrees and also the opposite angles are equal i.e <ABC = <CDA and <BAD = <BCD
Given
<CAD = 20 degrees
<BCE = 20 degrees (based on geometry)
<BAD = <CAD + <BCE
<BAD = 20 + 20
<BAD = 40 degrees
Since <BAD = <BCD, then <BCD = 40 degrees
Get <CDA
<CDA + <ABC + <BAD + <BCD = 360
<CDA + <CDA + <BAD + <BCD = 360
2 < CDA + 40 + 40 = 360
2< CDA + 80 = 360
2< CDA = 360-80
2< CDA = 280
< CDA = 280/2
< CDA = 140 degrees

A clearance rack is marked as 60% off the regular price to be taken at the register. If a jacket on the clearance rack is marked $239.99, what will it ring up for at the register
Answers
Answer:
$399.98
Step-by-step explanation:
Given
Mark down percent = 60%
Mark down price = $239.99
Required
Original price of the rack
Let x be the original price of the product. The equation to get x is as expressed below;
60% of x = 239.99
0.6x = 239.99
x = 239.99/0.6
x = 399.98
Hence the rack will ring up for $399.98 at the register
