Write an expression to represent how to calculate the area of a triangular sail.
Answer:
(b × h) ÷ 2
Step-by-step explanation:
Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

In the right ABC above, what is the length of the side BC?
!!!!!!!!!!!!!!
Answer:
look at the picture i have sent
In the right ABC above, the length of the side BC is 4.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Given;
Side BA= [tex]\sqrt{11}[/tex]
Side AC= [tex]\sqrt{5}[/tex]
BC^2=BA^2+AC^2
BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2
BC^2= 11+5
BC^2= 16
BC= 4

d = √(x2 - x2)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(-9, 6, -4)
Substitute the values in the above equation and you will get
d = √(-9)^2 + (6)^2 + (-4)^2
= √(81 + 36 + 16)

Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light is still good but she can be close to the sea life during her scuba dive Which two equations can be used to find the minimum and maximum depths Laurie wants to stay between?
Answer:
It should be the first one
Step-by-step explanation:
since positive ten would represent going further up and negative ten going further down, the diver would be within ten feet of her current position
Answer:
A) -30 - x = 10 and -30 - x = –10
Step-by-step explanation:
Part 1:
1) Isolate the variable x
-30 - x = 10
-x = 40
2) Multiply both sides by -1
x = -40
Therefore -30 - x = 10 is correct
Part 2:
1) Isolate the variable x
-30 - x = –10
-x = 20
2) Multiply both sides by -1
x = -20
Therefore -30 - x = –10 is also correct
Final Answer: -30 - x = 10 and -30 - x = –10

Answer:
5. a = 4
7. x = -8
9. x = -1
11. p = 1.1
13. x = -1
15. x = -4
Step-by-step explanation:
2.9a = 11.6
2.9a/2.9 = 11.6/2.9
a = 4
-3.7x = 29.6
-3.7x/-3.7 = 29.6/-3.7
x = -8
(x-5)(-3) = 18
(x-5)(-3)/-3 = 18/-3
x-5 = -6
x-5+5 = -6+5
x = -1
3.6 = -2p+5.8
3.6-5.8 = -2p+5.8-5.8
-2.2 = -2p
-2.2/-2 = -2p/-2
1.1 = p
2x+6 = -4x
2x+6-6 = -4x-6
2x = -4x-6
2x+4x = -4x-6+4x
6x = -6
6x/6 = -6/6
x = -1
21-6x = -11-14x
21-6x-21 = -11-14x-21
-6x = -14x-32
-6x+14x = -14x-32+14x
8x = -32
8x/8 = -32/8
x = -4
Answer:
5.) a= 4
7.) x= -8
9.)x= -1
11.) p= 1.1
13.) x= -1
15.) x= -4
Step-by-step explanation:
5.) divide 11.6 by 2.9a
7.)divide 29.6 by -3.7u
9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1
11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1
13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1
15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4
