Step-by-step explanation:
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?
We solve the above question using Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of depression = 19°
Distance between the boat and the shark = Adjacent = ? = x
Opposite = 28 feet
Hence:
tan 19 = 28/x
Cross Multiply
tan 19 × x = 28
x = 28/tan 19
x = 81.317904575 feet
Approximately = 81.3 feet
The distance between the boat and the shark is 81.3 feet

Amy owns 3 1/3 acres of farmland. She grows beets on 1/6 of the land. On how many acres
of land does Amy grow beets?
Plz
Answer:
5/9 acres
Step-by-step explanation:
3 1/3 areas is 10/3
1/6 of the land is covered with beets
[tex]\frac{10}{3} * \frac{1}{6} =\frac{10}{18}[/tex]
[tex]\frac{10}{18}[/tex] will simplify to [tex]\frac{5}{9}[/tex]
Hence the answer is 5/9 acres

In January the students in a class red 72 books in February they read 56 books what is the approximate percentage decrease in the number of books read from January to February
Answer: -12.5%
72 + 56 = 128
72 x / 128 x 100 = 56.25
56 / 128 x 100 = 43.75
43.75 - 56.25 = - 12.5

Mr. Gibbs bought number of shirts for the new members of his band. The cost for number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts did Mr. Gibbs buy?
Answer:
Number of shirts= 6
Step-by-step explanation:
Giving the following information:
The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.
First, we need to calculate the net total price paid for the shirts:
Net total cost= 77.49 - 3.99= $73.5
Now, the number of shirts bought:
Number of shirts= 73.5 / 12.25
Number of shirts= 6

Use substitution to solve the following system of equations.
x + 2y = 13
3x - 5y = 6
Answer:
{1} x + 2y = 13
{2} 3x - 5y = 6
x = 13 - 2y
substituting into {2}
3x -5y = 6
3( 13 - 2y) - 5y = 6
39 - 6y -5y = 6
-11y = 6 -39
y = -33 /-11
( minus and minus cuts in fraction, so the answer will come in positive)
y = 3
now , substituting into {1}
x + 2(3) = 13
x = 13 -6
x = 7
so,
the solution are:-
x = 7
y = 3
I hope this helps a little bit.

Which equation represents a circle that contains the point (-5, 3) and has a center at (-2, 1)? Distance formula: vaa -02 (x - 1)2 + ( + 2)2 = 25 (x + 2)2 + (-1)=5 O (* + 2) + (-1) - 25 (x-1) + ( + 2) = 5
Given:
The center of the circle = (-2,1).
Circle passes through the point (-5,3).
To find:
The equation of the circle.
Solution:
Radius is the distance between the center of the circle and any point on the circle. So, radius of the circle is the distance between the points (-2,1) and (-5,3).
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(-5-(-2))^2+(3-1)^2}[/tex]
[tex]r=\sqrt{(-5+2)^2+(2)^2}[/tex]
[tex]r=\sqrt{(-3)^2+(2)^2}[/tex]
On further simplification, we get
[tex]r=\sqrt{9+4}[/tex]
[tex]r=\sqrt{13}[/tex]
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle.
Substitute h=-2, k=1 and [tex]r=\sqrt{13}[/tex].
[tex](x-(-2))^2+(y-1)^2=(\sqrt{13})^2[/tex]
[tex](x+2)^2+(y-1)^2=13[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-1)^2=13[/tex].
Given the vertex and another point, write the equation in vertex form: vertex (2, -5) point (3, -2)
Answer:
y = 3(x - 2)² - 5
Step-by-step explanation:
Let the equation of the parabola is,
y = a(x - h)² + k
Here, (h, k) is the vertex of the given parabola.
Since, vertex of the parabola is (2, -5)
Equation of the parabola will be,
y = a(x - 2)²- 5
Since, parabola passes through a point (3, -2),
-2 = a(3 - 2)²- 5
-2 + 5 = a(1)
a = 3
Therefore, equation of the parabola will be,
y = 3(x - 2)²- 5

I really need help with the radius,diameter and area off circles and halfcircles
Answer:
Radius refers to the distance between the center of the circle to any point of the circle
Diameter refers to the distance between any two points on the circle passing through the center of circle, it is also equal to radiusx2
Area of circle = πr², where π is a constant (≈3.14159), r is the radius
Halfcircles is basically half of the circle. It has the same radius and diameter as it's full circle but the area of the halfcircle is equal to half of the area of the full circle.
