Find the area of a sector with an arc length of 40 cm and a radium of 12 cm
The required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
Sectoral area = arc / 2 × radius
Sectoral area = 40 / 2 × 12
= 20 × 12 = 240 cm²
Thus, the required area of a sector with an arc of 40 cm and a radius of 12 cm is given as 240 cm².

–0.4 = 3d + –10
pls answer and dont delete for no reason. again.
Answer:
3.2
Step-by-step explanation:
I'm guessing you want to find the value of D.
so,
-0.4 = 3d -10
3d = 9.6
d = 3.2
Answer: 3.2
Step-by-step explanation:
-0.4= 3d + (-10)
-0.4= 3d -10
add 10 to both sides
9.6 =3d
d= 9.6/3
d = 3.2

A and B are two cities.
a) measure the bearing of B from A.
b) Measure the bearing from A from B.
Answer:
B from A: about 29°A from B: about 209°Step-by-step explanation:
A bearing is measured clockwise from north. To do this measurement, we need to extend the line beteen A and B and extend the North-pointing line so they cross.* A protractor or other measuring tool is then used to measure the angle between the lines.
__
In the attached, we have found the angle between these lines to be about 29°. This is the angle between north and B, as seen from A.
29° = bearing of B from A
__
As seen from B, the angle is 180° more than the one of B from A. The bearing of A from B is ...
180° +29° = 209° . . . . . bearing of A from B
_____
* The angle measurement can be made between any set of lines that are coincident with or parallel to the north line and the line between A and B. In the attached, we attempted to maximize accuracy by using the lines on the figure, rather than creating parallel lines for the purpose of the measurement.
On a figure such as this, it is very difficult to get accuracy to even 0.1 degrees. For example, the geometry program that we used says the slope of the AB line is tangent(60.58°), so the bearing using that information is about 29.42°, not the 29.29° the same program reports as the measurement of the angle.
We don't have access to your original figure, and we can't account for any distortions that may have occurred in the copying and pasting of the image. Straight dilation will not change the angle, but most image reproduction processes have different scale factors in different directions, which will affect the angle measurement. YMMV

The water flow rate of a regular shower head is 3. 5 gallons per minute. At this rate it would cost $1. 90 for the water used for a 10 minute shower
Using proportions, it is found that the cost of 1 gallon of water, rounded to the nearest cent, is of $0.05.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that he uses 3.5 x 10 = 35 gallons for a 10 minute shower, which costs $1.9. Hence the cost of a gallon is of:
$1.9/35 = $0.05.

The endpoints of the diameter of a circle are (6, 0) and (-6, 0). What are the coordinates of the center of this circle?
Answer:
(0,0)
Step-by-step explanation:
a diameter means The average of two measurements of the diameter taken at right angles to each other. so if you try graphing you will be able to find out its (0,0) is the center of the circle coordinates
The coordinates of the center of this circle is (0,0).
What are the coordinates of a center of a circle?The center of a circle is the midpoint of the diameter. So, by using the midpoint formula, if the endpoints of the diameter are (a, b) and (c, d), then the coordinates of the center of circle are [(a + c)/2, (b + d)/2].
According to the question
The endpoints of the diameter of a circle are (6, 0) and (-6, 0).
now ,
(a,b) = (6, 0)
(c, d)= (-6, 0)
coordinates of the center of circle = [ [tex]\frac{a+c}{2} ,\frac{b+d}{2}[/tex] ]
⇒ [tex]\frac{6-6}{2} ,\frac{0+0}{2}[/tex]
⇒ (0,0)

Look at one of the formulas for the perimeter of a rectangle where l represents the length and w represents the width. 2(l + w)
What does the 2 represent in this formula?
Answer:
The question you are asking is a bit unclear but I might be able to offer some insight.
2(l + w) is sometimes used as the formula for the perimeter of a rectangle.
If l represents the length and w represents the width, then the perimeter (sum of the sides) is l + w + l + w.
This simplifies algebraically as 2l + 2w and can be factored into 2(l + w).
So, to find the perimeter of the rectangle you must double the sum of the length and width.

The diagonals of a kite meet at right angles. They also bisect each other. So the two triangles on the left and right side of the kite are congruent.
Because the smaller diagonal is bisected, you need only find the area of 1 of the triangles and double it.
1/2 of the smaller diagonal is the altitude of the triangle. The base is the other larger diagonal.
Solution
Area of the left triangle

altitude = 7.5
Base = 14 + 5 = 19
formula
Area = 1/2 * B * h
Solution
Area = 1/2 * 19 * 7.5

Vector u has an initial point at (−5, 2) and a terminal point at (−7, 9). Which of the following represents u in trigonometric form?
u = 7.28(cos 74.055°i + sin 74.055j)
u = 7.28(cos 105.945°i + sin 105.945°j)
u = 7.28(sin 74.055°i + cos 74.055°j)
u = 7.28(sin 105.945°i + cos 105.945°j)
Answer:
(b) 7.28 cis(105.945°)
Step-by-step explanation:
The trig form of a vector is always ...
magnitude(cos(angle)·i +sin(angle)·j)
Sometimes, that is abbreviated ...
magnitude cis(angle) or magnitude∠angle
where the "angle" is measured counterclockwise from the +x axis.
__
The forms showin in choices C and D can be rejected immediately because the sine and cosine coefficients are incorrectly placed. To differentiate between choices A and B, you need to know whether the angle is greater than 90°. The terminal point is above and left of the initial point, so the angle must be more than 90°. (It can help to plot the points on a graph.)
u = 7.28(cos 105.945°i + sin 105.945°j)
