Cost of child ticket = x
cost of adult ticket = 2x
2(2x) + 3(x) = 28
4x + 3x = 28
7x = 28
x = 28/7
x = 4
Child ticket cost 4
Adult ticket cost 8

In the given formula :

r = rate = 4.5% = 0.045

t = time = 7 years

P = principal = #3,700


e is an arbitrary number used in mathematics, which is approximately 2.7183


Replace the letters with the given information:

A = 3700e^0.045(7)

A = $5,069.96

Match each trigonometric function with its Unit Circle definition. Note that Angle A is correctly oriented for the Unit Circle d
PtichkaEL [24]
The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.

From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x

We can further deduce that
tan(Θ) = \frac{y}{x}
sec(Θ) = \frac{1}{cos(Θ)} = \frac{1}{x}
cosec(Θ) = \frac{1}{sin(Θ)} = \frac{1}{y}
cot(Θ) = \frac{cos(Θ)}{sin(Θ)} = \frac{x}{y}

Find the equation of the line in slope-intercept form (-1,-1) and (1,0)
ArbitrLikvidat [17]

Answer:

An equation in slope-intercept form of the line will be

  • y\:=\frac{1}{2}x-\frac{1}{2}

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the points

  • (-1, -1)
  • (1, 0)

Finding the slope between (-1,-1) and (1,0)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)

m=\frac{0-\left(-1\right)}{1-\left(-1\right)}

m=\frac{1}{2}

substituting m = 1/2 and (-1, -1) in the slope-intercept form of the line equation to determine the y-intercept

y = mx+b

-1=\frac{1}{2}\left(-1\right)+b

-\frac{1}{2}+b=-1

Add 1/2 to both sides

-\frac{1}{2}+b+\frac{1}{2}=-1+\frac{1}{2}

b=-\frac{1}{2}

substituting m = 1/2 and b = -1/2 in the slope-intercept form of the line equation

y = mx+b

y\:=\frac{1}{2}x+\left(-\frac{1}{2}\right)

y\:=\frac{1}{2}x-\frac{1}{2}

Therefore, an equation in slope-intercept form of the line will be

  • y\:=\frac{1}{2}x-\frac{1}{2}
