Find the value of m
Answer:
m = 9
Step-by-step explanation:
Using the rules of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]
Then
[tex](\frac{1}{27}) ^{m}[/tex] × [tex](81)^{-1}[/tex] = 243 ← express all values to base 3
[tex](\frac{1}{3^3}) ^{m}[/tex] × [tex](3 ^4)^{-1}[/tex] = [tex]3^{5}[/tex]
[tex](3^-3)^{m}[/tex] × [tex]3^{-4}[/tex] = [tex]3^{5}[/tex]
[tex]3^{-3m}[/tex] × [tex]3^{-4}[/tex] = [tex]3^{5}[/tex]
[tex]3^{(-3m-4)}[/tex] = [tex]3^{5}[/tex]
Since bases on both sides are equal, both 3 , then equate exponents
- 3m - 4 = 5 ( add 4 to both sides )
- 3m = 9 ( divide both sides by - 3 )
m = - 3

The cost of a piece of ribbon is directly proportional to the length of the ribbon. The cost of 8 yards of ribbon (without tax) is $5.60. The sales tax rate is 6.35%. What does it cost for 10 yards of ribbon, including tax?
Answer: $7.44
Step-by-step explanation:
The cost of a piece of ribbon is directly proportional to the length of the ribbon.
A yard is therefore:
= 5.60/8
= $0.70
10 yards will cost:
= 0.70 * 10
= $7.00
Including sales tax:
= 7.00 * (1 + 6.35%)
= $7.44
The next model of a sports car will cost 12.3% more than the current model. The current model costs $49,000. How much will the price increase in dollars?
What will be the price of the next model?
Answer:
The price increase is $6,027
The price of the next model is $55,027
Step-by-step explanation:
Find the cost of the next model by multiplying 49,000 by 1.123
49,000(1.123)
= 55,027
Find the price increase by finding the difference:
55,027 - 49,000
= 6,027
The price increase is $6,027
The price of the next model is $55,027
Answer:
First write the percent as a decimal to make calculating for the answer easier. Then, u see that its telling you it will be 12.3% more than current price.

A(3,0) and B(-3,0) are the two fixed points Find the locus of a point P at which AB subtend a right angle at P
Answer:
[tex]y^2+x^2=9[/tex]
Step-by-step explanation:
Let's take a general point P(x,y). If there is a right angle at P then the slopes of the lines passing through AP and BP must be perpendicular.
Two lines of slopes m1 and m2 are perpendicular if:
m1*m2=-1
The slope of the line passing through P(x,y) and A(3,0) is:
[tex]\displaystyle m_1=\frac{y-0}{x-3}=\frac{y}{x-3}[/tex]
The slope of the line passing through P(x,y) and B(-3,0) is:
[tex]\displaystyle m_2=\frac{y-0}{x+3}=\frac{y}{x+3}[/tex]
Substituting in the equation:
[tex]\displaystyle \frac{y}{x-3}\cdot\frac{y}{x+3}=-1[/tex]
Operating:
[tex]\displaystyle \frac{y^2}{(x-3)(x+3)}=-1[/tex]
[tex]y^2=-(x-3)(x+3)[/tex]
[tex]y^2=-(x^2-9)[/tex]
[tex]y^2=-x^2+9[/tex]
[tex]\boxed{y^2+x^2=9}[/tex]
The locus is a circle centered at the origin with radius 3
A square playground has sides that each measure 120 feet in length. On a scale drawing, 1/4 inch represents 5 feet on the playground. How long is a side of this playground on the scale drawing?
Answer:
6 Inches
Step-by-step explanation:
Per the above, we were given that;
1/4 inch = 5 feet
But,
X inch = 120 feet
We would represent the above as a ratio
1/4 inch / X inch = 5 feet / 120 feet
1/4 inch / X inch = 1 feet / 24 feet
When we cross multiply, we'll have
1/4 inch × 24 feet = X inch × 1 feet
X = 6 inches
Answer:
6 inches

How much interest would you pay on a $12000 loan at 5% for 6 years
Answer:
Interest=$3600
Step-by-step explanation:
I = P * r * x * t
Where:
P is the principal amount, $12000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 6....year(s) time periods.
So, t is 6....year time periods.
To find the simple interest, we multiply 12000 × 0.05 × 6 to get that:
The interest is: $3600.00
Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),
or 12000.00 + 3600.00 = 15600.00. For example:
If you borrowed the $12000.00, you would now owe $15600.00
If you loaned someone $12000.00, you would now be due $15600.00
If owned something, like a $12000.00 bond, it would be worth $15600.00 now.

Find the value of each variable.
Answer:
a = 20
b = 30
Step-by-step explanation:
1) Solving for a
From the diagram above, KL + ML = An arc
Hence, we add them up
110° + 130° = 240°
1/2 of 240° = 120°
Solving for a°
180° = 120° + 3a (sum of opposite angles in a cyclic quadrilateral)
180° - 120° = 3a
60° = 3a
a = 60/3
a = 20
2) Solving for b
The sum of the exterior angles of a circle = 360°
Hence:
360° = KL + ML + JM + JK
KL = 110°
ML = 130°
JM = 54°
JK = ??
JK = 360 - (110° + 130° + 54°)
JK = 360 - 294
JK = 66°
Adding up JK + JL = 54° + 66°
= 120°
1/2 of 120° = 60°
Hence:
60° + 4b = 180°(sum of opposite angles in a cyclic quadrilateral)
4b = 180° - 60°
4b = 120°
b = 120/4
b = 30

Answer: I think it’s the 8y= 7x + 6
Step-by-step explanation:
Well to make it easier, put it in slope intercept form, which that is y= -8/7x + 1/7. Since perpendicular lines are opposite sign reciprocal of the original equation, we know the slope of the perpendicular line would be positive, since the original was negative. So the answer would be 8y = 7x + 6
9514 1404 393
Answer:
(b) 8y = 7x +6
Step-by-step explanation:
You can always make a perpendicular line by swapping the x- and y-coefficients, and negating one of them. In the process, ignore the constant.
Swapping the coefficients in the given equation gives you ...
-8y = 7x + constant
Negating the y-coefficient, you get ...
8y = 7x + constant . . . . . the equation of a perpendicular line
Using constant = 6 to match an answer choice, you can see that this matches ...
8y = 7x +6
