The cost price of a boat is marked up by 8%.
a. Calculate the cost price if the marked up price is $43200.
Answer:
$40000
Step-by-step explanation:
The formula is x*1.08 = 43200. If you want to find the original price then isolate x. x*1.08 = 43200 -> x = 40000.
The ordered pair D(0,-5) is translated 2 units left and 6 units up. Which of the following describes the translation using translation notation?

C. (x+6, y-2)
D. (x-2, y+6)
Answer:
Variant D

What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The coordinates of a point are given as (x,y).
Now, the x-coordinate is on the horizontal axis, therefore, if the point is moving right it is going in the positive direction, while if the point is moving in the left direction it is going in the negative direction.
Similarly, the y-coordinate is on the vertical axis, therefore, if the point is moving upwards it is going in the positive direction, while if the point is moving in downwards its direction it is going in the negative direction.
Given that the coordinates are translated as 2 units left and 6 units up. Therefore, we can write,
(x,y) → (x-2, y+6)
Hence, the translation using translation notation can be described as
(x-2,y+6).

help me please!!!!!!!!
Answer: it would be 4/2
Step-by-step explanation:
Answer:
the slope is 4/2, which can be simplified to 2/1.
Step-by-step explanation:
to find a slope, you have to identify two points that the line goes through. for example, in this problem. the slope travels through (0,0) and (2,4). from (0,0) tp (2,4), the slope travels to the side two points and up four. in the equation y=mx+b, m would be 4/2 or 1/2 since it's the slope. hope this helps a bit!!
Does this diverge or converge?
Answer:
L = 7/6 , and the correct option is B, the series diverges.
Step-by-step explanation:
Here we have that:
[tex]an = \frac{(3n + 3)*7^n}{6^{n+4}}[/tex]
Now we want to see the quotient test, then we need to do find the value of the quotient as n tends to infinity. Then we first need to find the quotient:
[tex]a(n + 1)/a(n) = \frac{(3(n + 1) + 3)*7^{n + 1}}{6^{n + 1 + 4}}*\frac{6^{n + 4}}{(3*(n) + 3)*7^{n}}[/tex]
We can simplify the right part to get:
[tex]\frac{(3(n + 1) + 3)*7^{n + 1}}{6^{n + 1 + 4}}*\frac{6^{n + 4}}{(3*(n) + 3)*7^{n}}= \frac{(3n + 3 + 3)*7^{n + 1}}{6^{n + 5}}*\frac{6^{n + 4}}{(3*n + 3)*7^{n}}[/tex]
[tex]\frac{(3n + 3 + 3)*7^{n + 1}}{6^{n + 5}}*\frac{6^{n + 4}}{(3*n + 3)*7^{n}}= \frac{(3n + 3 + 3)*7}{(3*n + 3)*6}[/tex]
Now we want to find the limit of this as n goes to infinity, we can see that both parts will tend to infinity, then we need to use the Lhopital rule and find the limit of the quotient of the first derivatives.
The first derivatives are:
For the denominator: (3*6)
For the numerator: (3*7)
Then we need to find the limit as n goes to infinity to:
[tex]\frac{3*7}{3*6} = \frac{7}{6}[/tex]
But this does not depend on the value of n, then the limit is just 6/7.
L = 7/6
And 7/6 > 1.
Then we can conclude that our series diverges.

The Suarez family paid $12.00 for 3 movie tickets. How much would they have paid for 9 tickets?
Answer:
$36 (see below)
Step-by-step explanation:
First, you have to find how much they paid for one ticket.
If they paid $12 for 3, then they paid $4 for 1.
You could've also use a ratio:
$12 $x
-------- = --------
3 1
Cross multiply:
$12 (1) = $3x
$12 = $3x
$4 = x
So $4 for 1 ticket.
To find the cost of 9 tickets, just multiply the price by the number of tickets, which is:
$4 (9) = $36

Write the standard form of the equation of the circle with the given characteristics. Center: (3, 9); Solution point: (−2, 21)
Given:
Center of a circle is (3,9).
Solution point is (-2,21).
To find:
The standard form of the circle.
Solution:
Radius is the distance between center (3,9) and the solution point (-2,21).
[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(-2-3)^2+(21-9)^2}[/tex]
[tex]r=\sqrt{(-5)^2+(12)^2}[/tex]
[tex]r=\sqrt{25+144}[/tex]
On further simplification, we get
[tex]r=\sqrt{169}[/tex]
[tex]r=13[/tex]
The radius of the circle is 13 units.
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center and r is the radius.
Putting h=3, k=9 and r=13, we get
[tex](x-3)^2+(y-9)^2=(13)^2[/tex]
[tex](x-3)^2+(y-9)^2=169[/tex]
Therefore, the standard form of the circle is [tex](x-3)^2+(y-9)^2=169[/tex].

A village is 10km on a bearing 050° from a point O. Calculate how far the village is north of O.
Answer:
7.66 km
Step-by-step explanation:
Let distance village is ; north of O = x
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Opposite = x
Hypotenus = 10
θ = 50°
Sin50 = x / 10
0.7660444 = x / 10
x = 0.7660444 * 10
x = 7.6604444
x = 7.66
The equation of line L is 2x+y=3
Line M is parallel to line L and passes through
(1,−6)
Work out the equation of line M.
Give your answer in the form
y=ax+b
(3 marks)
Answer:
y = -2x - 4
Step-by-step explanation:
We transform the line equation of L:
2x + y = 3 --(-2x)--> f(x) = y = -2x + 3
We now know that L intersects the y-axis at 3 and it has a slope of -2.
In order to construct a parallel line M, it needs to have an identical slope to L.
All we need to do now is to move one step from the given point (1,-6) towards 0 with the predetermined slope of -2, resulting in the point (0,-4).
Since we know slope and intersection with the y-axis (0,-4), we can construct the line equation:
f(x) = y = -2x - 4 for line M.

Answer:
FH ≈ 4.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos64° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{FH}{GH}[/tex] = [tex]\frac{FH}{10}[/tex] ( multiply both sides by 10 )
10 × cos64° = FH , then

Betsy uses 8.8 of blue paint and white paint to paint her bedroom walls. 1/4 of this amount is blue paint. And th rest is white how many pints of white paint did she use to paint her bedroom walls
Answer:
6.6 pints of white paint is used to paint the bedroom walls
Step-by-step explanation:
Pints of blue paint used to paint the bedroom walls = 8.8
Ratio of blue paint used = [tex]\frac{1}{4}[/tex]
Therefore,
Ratio of white paint used = [tex]1-\frac{1}{4}=\frac{3}{4}[/tex]
Pints of white paint used to paint the bedroom walls = [tex]\frac{3}{4}(8.8)=3(2.2)=6.6[/tex]
Therefore,
6.6 pints of white paint is used to paint the bedroom walls.
