Answer:

The base is 3.

Step-by-step explanation:

The distance between Casey and the base of the lighthouse is 49 ft.

The angle of elevation refers to the angle formed by the straight horizontal line and an object. The crosshair of an observer is usually above the horizontal. 

The angle of depression is the angle formed by the horizontal and a downward angle to an object. The crosshair of an observer is usually above below the horizontal.

The distance between Casey and the base of the lighthouse can be determined by using the tangent of trigonometry.

Step-by-step explanation:

410 is the total amount paid

so 50 dollars was a base fee for the service charge

and 90 was per tire. Because we dont know how many tires she bought 90 x number of tires(t) = 90t

Answer:

Step-by-step explanation:

4x + 4y = -37

2x + 5y = -17

we are told to use elimination ,   instead of substitution,

meaning get rid of the x or y  in one of the equations.

Part C :   let's multiply (2x + 5y = -17 ) *  (-2)  so we get

-4x - 10y = 34    , then add

4x + 4y = -37

0x -6y = -3      now we have only one variable ,  y

because both sides have a minus sign, we can just drop it

6y = 3   ( divide both sides by 6)

y = 3/6

Part B : y = 1/2    we now know y

plug in the y value into  1st equation.

4x + 4(1/2) = -37

now solve for x

4x + 2 = -37

4x = -39

Part A :  x = - 39/4

[tex]\dfrac{5(3+\sqrt{5})\sqrt{3-\sqrt{5}}}{4}[/tex]

[tex]\textsf{or}\quad \dfrac{5\sqrt{3+\sqrt{5}}}{2}[/tex]

Step-by-step explanation:

[tex]\textsf{Given expression}:\dfrac{5}{\sqrt{3-\sqrt{5}}}[/tex]

Method 1

[tex]\textsf{Multiply by the conjugate}\quad \dfrac{\sqrt{3-\sqrt{5}}}{\sqrt{3-\sqrt{5}}}:[/tex]

[tex]\implies \dfrac{5}{\sqrt{3-\sqrt{5}}} \times \dfrac{\sqrt{3-\sqrt{5}}}{\sqrt{3-\sqrt{5}}}=\dfrac{5\sqrt{3-\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})}[/tex]

Simplify the denominator using the radical rule [tex]\sqrt{a} \sqrt{a} =a[/tex]:

[tex]\implies (\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})=3-\sqrt{5}[/tex]

Therefore:

[tex]\implies \dfrac{5\sqrt{3-\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3-\sqrt{5}})}= \dfrac{5\sqrt{3-\sqrt{5}}}{3-\sqrt{5}}[/tex]

[tex]\textsf{Multiply by the conjugate}\quad \dfrac{3+\sqrt{5}}{3+\sqrt{5}}:[/tex]

[tex]\implies \dfrac{5\sqrt{3-\sqrt{5}}}{3-\sqrt{5}} \times \dfrac{3+\sqrt{5}}{3+\sqrt{5}}=\dfrac{5\sqrt{3-\sqrt{5}}(3+\sqrt{5})}{(3-\sqrt{5})(3+\sqrt{5})}[/tex]

Simplify the denominator:

[tex]\implies (3-\sqrt{5})(3+\sqrt{5})=9+3\sqrt{5}-3\sqrt{5}-5=4[/tex]

Therefore:

[tex]\implies \dfrac{5(3+\sqrt{5})\sqrt{3-\sqrt{5}}}{4}[/tex]

Method 2

[tex]\textsf{Multiply by the conjugate}\quad \dfrac{\sqrt{3+\sqrt{5}}}{\sqrt{3+\sqrt{5}}}:[/tex]

[tex]\implies \dfrac{5}{\sqrt{3-\sqrt{5}}} \times \dfrac{\sqrt{3+\sqrt{5}}}{\sqrt{3+\sqrt{5}}}=\dfrac{5\sqrt{3+\sqrt{5}}}{(\sqrt{3-\sqrt{5}})(\sqrt{3+\sqrt{5}})}[/tex]

Simplify the denominator using the radical rule [tex]\sqrt{a} \sqrt{b} =\sqrt{ab}[/tex]:

[tex]\implies (\sqrt{3-\sqrt{5}})(\sqrt{3+\sqrt{5}})=\sqrt{(3-\sqrt{5})(3+\sqrt{5})[/tex]

In here

Answer:

[tex]f(x)=1250*(\frac{4}{5})^x[/tex]

Step-by-step explanation:

1. The equation in slope-intercept form is: y = -3/2x + 7/2

2. y = -3/2x - 18

3. Both lines have the same slope, they are therefore parallel.

Two lines that are parallel will have the same slope (m), and is represented by the equation in slope-intercept form as, y = mx + b.

1. Rewrite 3x + 2y = 4 in slope-intercept form:

2y = -3x + 4

y = -3x/2 + 4/2

y = -3/2x + 2

The slope is -3/2. Therefore, the slope (m) of the line that passes through (-1, 5) would be -3/2.

Substitute m = -3/2, and (a, b) = (-1, 5) into y - b = m(x - a):

y - 5 = -3/2(x - (-1))

y - 5 = -3/2(x + 1)

Rewrite in slope-intercept form:

2(y - 5) = -3(x + 1)

2y - 10 = -3x - 3

2y = -3x - 3 + 10

2y = -3x + 7

y = -3x/2 + 7/2

y = -3/2x + 7/2

2. The slopes of perpendicular lines are negative reciprocal to each other.

Rewrite 2x + 3y = 4

3y = -2x + 4

y = -2/3x + 4/3

The slope of the ine that passes (-2, 15) would be -3/2.

Substitute (a, b) = (-2, 15), and m = -3/2 into y - b = m(x - a):

y - 15 = -3/2(x - (-2))

y - 15 = -3/2x - 3

y = -3/2x - 3 - 15

y = -3/2x - 18

Therefore, the equation in slope-intercept form of the line that passes through (-2, 15) is: y = -3/2x - 18.

3. Given the equations, 2x – y = −1 and 4x – 2y = 6:

Rewrite in slope-intercept form and find their slope

2x - y = -1

-y = -2x - 1

y = 2x + 1 (slope if 2)

4x - 2y = 6

-2y = -4x + 6

y = -4x/-2 + 6/-2

y = 2x - 3 (slope is 2)

Both lines are therefore, parallel.
