Answer:
Can you show us the two expressions?
Step-by-step explanation:
can anyone solve this?
Answer:
Using the height theorem:
[tex]n^2=8*4=32=>n=4\sqrt{2}[/tex]
Now we can easily use the pythagorean theorem:
[tex]8^2+(4\sqrt{2})^2 =64+32=96=>m=\sqrt{96} =4\sqrt{6}[/tex]

Step-by-step explanation:
Formula of circumference:
3.14(pi) x 2(the number is just always there when finding circumference) x radius(half of your diameter or just your given radius).
A. zero
B. negative
C. positive
Answer:
B
Step-by-step explanation:
If its pointing towrds the ground its negative but if its pointing up its positive. If its a straight line on the axis point its zero. Hope this helps.
dion places a ladder against The side of his house as shown in the diagram below. Dion’s water is 26 feet long, and he places the ladder at a 70° angle with the ground, represented by zero
Complete question :
dion places a ladder against The side of his house as shown in the diagram below. Dion’s water is 26 feet long, and he places the ladder at a 70° angle with the ground, How high does the ladder reach up the side of the building?.
Answer:
24.43 feets
Step-by-step explanation:
Using trigonometry :
Sinθ = opposite / hypotenus
Opposite = height, h
Hypotenus = 26
Sin 70° = h / 26
0.9396926 * 26 = h
height, h = 24.43 feets
The sine rule is the ratio of the height and hypotenuse. Then the height of the wall is 24.43 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
Dion places a ladder against the side of his house as shown in the diagram below.
Dion’s water is 26 feet long, and he places the ladder at a 70° angle with the ground, represented by zero.
We have
Hypotenuse (H) = 26 ft
Let h be the height of the la
Then the height of the wall will be given by the sine rule.
[tex]\rm h = H sin \ \theta \\\\h = 26 * sin \ 70^o\\\\h = 24.43 \ ft[/tex]
The height of the wall is 24.43 ft.

In Greenville, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 7 kilometers and the distance between the courthouse and the city pool is 25 kilometers, how far is the library from the community pool?
Answer:
24 km
Step-by-step explanation:
this is a right triangle
use the pythagorean theorem
a² + b² = c²
a² + 7² = 25²
a² + 49 = 625
Subtract 49 from both sides
a² = 576
Take the square root of oth sides
a = 24

Two airplanes leave an airport at the same time, the first headed due north and the second at a bearing of N42^ E . At 2:00PM, the first airplane is 312 miles from the airport while the second airplane is 487 miles from the airport. Assuming both followed linear paths from the airport, how far apart are the two airplanes at 2:00PM?
Answer:
The two airplanes are about 330miles apart.
Step-by-step explanation:
The diagram interpreting the question has been attached to this response.
As shown in the diagram,
i. the airplanes leave at point C.
ii. at 2.00pm the first and second airplanes are at points A and B respectively, where they are 312miles and 487miles away from the starting point C in directions due north and N42E from the point C.
iii. the points A, B and C form a triangle with sides a, b and c.
To solve for the value of c which is the distance between the two planes at 2.00pm, the cosine rule is used.
c² = a² + b² - 2abcosC --------------(i)
where;
b = 312miles
a = 487miles
C = 42°
Substitute these values into equation (i) and solve as follows;
c² = (487)² + (312)² - 2(312)(487)cos(42)
c² = (237169) + (97344) - 303888cos(42)
c² = (237169) + (97344) - 303888(0.7431)
c² = 334513 - 225819.1728
c² = 108693.8272
Take the square root of both sides
√c² = √108693.8272
c = 329.69
c ≅ 330miles
Therefore, the two airplanes are far apart by 330miles

Explain how you use a net to find the surface area of a prism.
Answer:
Hello, Here is your answer.
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
Answer:
Step-by-step explanation:
By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

sale committee wants to raise $186 for a donation to a local charity they set a size $12 of their profit at the end of each day how many days will it take them to raise enough money for the whole donation
Answer:
15 and a half days
Step-by-step explanation:
Since they earn $12's each day you would do $186 divided by $12 which would be 15.5 so it would take them 15 and a half days to raise $186.
Answer:
Sorry if this is late, but I hope you understand now.
Step-by-step explanation:
It's 16 days actually, if you divide 186 divided by 12, it's 15.5 we can say, that 5 should be rounded up or down. 15.5 is a fraction of 15/5 so if we rounded it, it would be 16. That's our newer version of rounding. 5 is higher, 4 is lower. Use that to help you :) I hope you understand even though it late

Step-by-step explanation:
sin (19) = 67/x *put sin (19) over 1 & cross multiply
x (sin (19)) = 67 *divide by sin (19)
x = 67/sin (19)
x = 205.79 = 205.8
