two soccer players are warming up by kicking soccer balls at a goalie. the two players are located 10 yards apart, and the angle from each player to the goalie is 64° and 75°, respectively. what is the distance from the farthest soccer player to the goalie?
Using the law of sines, it is found that the distance from the farthest soccer player to the goalie is 14.723 yards.
Given,
The distance between the two players = 10yards
The angle from each player to the goalie is 64° and 75°, respectively
We have to find,
the distance from the farthest soccer player to the goalie.
In this problem, considering that the sum of the internal angles of a triangle is of 180º, the angle that the goalie makes with the players is given by:
∠A = 180-(∠B+∠C)
∠A = 41°
Using Sine rule
AC/Sin B = BC / Sin A
AC = 10yrd*Sin75°/Sin41°
AC = 14.723 yards
The farthest distance is of 14.723 yards.

jean gray earns a graduated commission of 4 on her first $2000 of sales and 8 on all sales over $2000 jean's sales for the past week totaled $3925
Her commission for the week was $234.
It is given the total earning in past week = $3,925 and jean earns 4% for the first $2000
So, the commission = $2000 x 4/100 = $80
To find additional sales, the formula to refer is
Add –on sales = total sales – base sales
= 3,925 – 2000
= 1,925
For the $1,925 sales, Jeans earns 8% commission, Her commission
= 1,925*0.08 = $154

18 Shifting the origin to another point (h,k) without Changing the directions of the axes. If P(x,y) with reference to original axes changes to P(X,Y) with reference new axes then i) x=X-h, y=Y-k ii) x=X-h,y=Y+k iii) x= x+h, y=Y+k iv)x=x-y=Y-k
If we shift the origin without changing the direction and point P(x, y) is changed to P(X, Y) then the new coordinates will be x = X + h and y = Y + k.
Shifting of origin is the phenomenon of changing the coordinates of the origin which is generally (0, 0) to another point which has coordinated (h, k). This phenomenon is usually carried out graphically. This is done when there is difficulty to solve the problems in coordinate geometry when we take the origin at (0, 0).
If we shift the origin which is at P(x, y) to another point (h, k) then the coordinates of new point P(X, Y) will be
x = X + h and y = Y + k
If h is positive, then coordinates will be x = X + h and if h is negative then coordinates will be x = X - h. If k is positive, then coordinates will be y = Y + k and if k is negative then coordinates will be y = Y - k.

a circle has a circumference of 615.44615.44615, point, 44 units. what is the radius of the circle? use 3.14 for \piπpi and enter your answer as a decimal.
A circle with a circumference of 615.44 units has a radius of 98 units.
A circle is a round closed figure where all its boundary points are equidistant from a fixed point called the center.
The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant [tex]\pi[/tex] and the diameter of the circle.
C = [tex]\pi[/tex]D
The diameter (D) is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center. On the other hand, the radius (r) of a circle is the distance from the center of a circle to any point on the circumference of the circle. Radius is half of the diameter.
If r = 1/2 D, then
D = 2r
Evaluating the value of Din the formula of the circumference,
C = [tex]\pi[/tex](2r)
C = 2[tex]\pi[/tex]r
Using the value of [tex]\pi[/tex] as 3.14 and the circumference as 615.44 units,
evaluate the equation.
C = 2[tex]\pi[/tex]r
615.44 = 2(3.14)r
r = 615.44/ (2*3.14)

Solve for "x"
4 (2x (2x - 1) - 1 (2x - 1)) = 0
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
4 • ((2x • (2x - 1)) - (2x - 1)) = 0
The rule says: To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (2x-1) and the exponents are :
1, as (2x-1), is the same number as (2x-1)1
and 1, as (2x-1) is the same number as (2x-1)1
The product is therefore, (2x-1)(1+1) = (2x-1)2
4 • (2x - 1)2 = 0
4.2 Solve : (2x-1)2 = 0
(2x-1) 2 represents, in effect, a product of 2 terms which is equal to zero
For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means: 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2 = 0.500
Answer:
x = 1/2.
Step-by-step explanation:
4 (2x (2x - 1) - 1 (2x - 1)) = 0
(2x (2x - 1) - 1 (2x - 1)) = 0
(2x - 1) is common to both parts.
(2x - 1)(2x - 1) = 0
2x - 1 = 0
x = 1/2.

The length of the hypotenuse AB is approximately 6.53 units.
In a right angled triangle the side opposite the right angle or the largest side is called the hypotenuse of the triangle.
The length of the hypotenuse is calculated using trigonometric ratios. If in a right-angled triangle, the base angle is θ then:
sin θ = perpendicular ÷ hypotenusecos θ = base ÷ hypotenusetan θ = perpendicular ÷ baseIn the given figure we see in ΔABC
AB is the hypotenuse. ∠BAC = 40 ° AC is the base and BC is the perpendicular.
(The side that contains the given angle is the base and the side opposite the given angle is taken as perpendicular)
Now cos ∠BAC = BC ÷ AB
or, cos 40° = 5 ÷ AB

A submarine is only allowed to change its depth by rising toward the surface in 60-meter stages. It starts off at -340 meters.
At what depth is it after:
1 stage meters
2 stages meters
4 stages meters
How many full stages will it take to return to the surface?
Answer:
Can you only pick one answer?
Answers:
depth after 1 stage is -280 meters depth after 2 stages is -220 meters depth after 4 stages is -100 meters how many stages to return to the surface? 6 stages==========================================================
Explanation:
After 1 stage, the depth is -340+60*1 = -280 meters. In other words, it's 280 meters below the surface.
After 2 stages, the depth is now -340+60*2 = -220 meters
After 4 stages, the depth is -340+60*4 = -100 meters
After n stages, the depth is -340+60n. Set this equal to zero and solve for n.
-340+60n = 0
60n = 340
n = 340/60
n = 5.667 approximately
This rounds to n = 6
After n = 5 stages, the depth is -340+60n = -340+60*5 = -40 meters
After n = 6 stages, the depth is -340+60n = -340+60*6 = 20 meters, so the submarine is now at the surface. Of course the sub cannot fly to a height of 20 meters above the ocean's surface, so the highest it can go is 0 meters at the surface itself. This means the 6th stage is a movement of 40 meters (instead of 60 meters).
