Step-by-step explanation:
14.) 20
15) 16
16) true
Answer:
20, 16, true
Step-by-step explanation:
The input is the number of rides, or the x-coordinate. The output is the dollars remaining on card, or the y-coordinate. We know this because the number of rides dictates how much money is on the card.
14. The question is asking for the output when the input is ten. Thus, we need to find the y-coordinate on the line when the x-coordinate is 10. We see that (10,20) is on the line, so then our output (or y-coordinate) is 20.
15. The question is asking for the input when the output is five. Thus, we need to find the x-coordinate on the line when the y-coordinate is 5. We see that (16,5) is on the line, so then our input (or x-coordinate) is 16.
16. 7 rides is the x-coordinate, and 27.50 is the cost, or the y-coordinate. However, this is true because even though the y-coordinate is NOT the cost of the rides, but the amount of money remaining on the card AFTER the rides are cashed in, 27.50 is half of 45 dollars, so then if 27.50 is spent on the rides, there will still be 27.50 left over on the card. Thus, it is true.

(1 - sinθ)/ cosθ = 1/cosθ - sinθ / cosθ = secθ - tanθQuestion 2The first part without root:
(1 + cosθ) / (1 - cosθ) = (1 + cosθ)(1 + cosθ) / (1 - cosθ)(1 + cosθ) (1 + cosθ)² / (1 - cos²θ) = (1 + cosθ)² / sin²θIts square root is:

(1 - cosθ) / (1 + cosθ) = (1 - cosθ)²/ (1 + cosθ)(1 - cosθ) = (1 - cosθ)²/ (1 - cos²θ) =(1 - cosθ)²/sin²θIts square root is:
(1 - cosθ) / sinθ = 1/sinθ - cosθ / sinθ =cosecθ - cotθSum of the results:
cosecθ + cotθ + cosecθ - cotθ = 2cosecθStep-by-step explanation:
Question 1:
Consider the left-hand side
[tex] \sqrt{ \frac{ 1 - \sin\theta }{1 + \sin\theta} } = \sqrt{ \frac{ 1 - \sin\theta }{1 + \sin\theta} \times \frac{1 - \sin\theta }{1 - \sin\theta } }[/tex]
[tex] = \sqrt{ \frac{ {(1 - \sin\theta )}^{2} }{(1 - { \sin}^{2}\theta) } } = \frac{1 - \sin\theta }{ \cos\theta} [/tex]
[tex] = \frac{1}{ \cos\theta} - \frac{ \sin\theta}{\cos\theta } [/tex]

An otter is swimming in the deep area of his tank at the zoo. The surface area of the otter's back is A
Answers
The equation of the magnitude of the force applied at the back of otter is F is (P+P0)A F is ( P + P 0 ) A .
What does the term magnitude of the force mean?The amount that encapsulates the force's power is known as its magnitude. Consider the following scenario: the force is 10 N in the east. The direction is indicated by "towards east," while the force is indicated by "10." Magnitude may be thought of as simply the "value" or "amount" of any physical quantity.
The surface area of the otter's back is A = 0.55 m2.
The fluid pressure at the depth of the otter is P = 11500 Pa.
Thus, the equation of the magnitude of the force applied at the back of otter is F=(P+P0)A F = ( P + P 0 ) A .
The complete question is
An otter is swimming in the deep area of his tank at the zoo. The surface area of the otter's back is A = 0.55 m2. The fluid pressure at the depth of the otter is P = 11500 Pa.

Answer:
A) -2 - i√3 , -2 + i√3
Step-by-step explanation:
Solve using quadratic formula
x² + 4x + 7 = 0
The Almighty Formula
= -b ± √b² - 4ac/2a
Where ax + bx² + c = 0
From the above question
a = 1, b = 4, c= 7
Hence,
-4 ± √4² - 4 × 1 × 7/2 × 1
-4 ± √16 - 28/2
=( -4 ± √-12)/2
Since
b² - 4ac < 0
We have two complex roots
Simplifying
( -4 ± √-12)/2
= -4/2 ± √-12/2
= -2 ± 2√3i/2
= -2 ± √3i
Therefore,
-2 - √3i , -2 + √3i

Write an equation of the line passing through the point (1,8) and parallel to y=−3x+10
Answers
The equation of the line is 3x + y - 11 = 0.
The slope-intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
First we find the slope of the line y=-3x+10 by placing it into slope-intercept form:
y = -3 x + 10
Therefore, the slope of the line is m= -3
Now since the equation of the line with slope m passing through a point
(x₁ ,y₁) is y-y₁ = m(x-x₁)
Here the point is (1,8) and slope is m= -3, therefore, the equation of the line is:
y - 8 = -3(x - 1)
y - 8 = -3x +3
3x + y - 11 = 0
Hence, the equation of the line is 3x + y - 11 = 0.

The direction of this transmission is always determined by the temperature differential between the bodies.
To achieve an equilibrium temperature, heat is transferred from the hotter to the cooler body.
As a result of the fact that a body and its surrounds are at different temperatures, we can infer that heat is the energy that is transferred between them.

The response to the given domain range questions is [go f oh]. (9) = 5(18^2 - 1 )
What are the domain and range?Domain and range. A function's authorised range of values is known as its domain. The x values in a function like f make up this set (x). A function's range is the collection of values that it can take as input. When we enter an x value, the function outputs this set of values.
According to the given information:f(x) = x^5 – 1, g(x) = 5x^2, and h(x) = 2x
[g o f o h](9)=g(f(h(9))
Let's find h(9) first
h(x)= 2x
h(9)= 2(9) =18
Now plug in 18 for h(9)
[g o f o h](9)=g(f(h(9)) = g(f(18))
now we find f(18)
f(x) = x^5 – 1, f(18)= 18^5 -1
Now we plug in 18^5 -1 for f(18)
[g o f o h](9)=g(f(h(9)) = g(18^5 -1)
Plug it in g(x)
g(x)= 5x^2

Liam Brought 5/8 Pound of cherries. Harrison Brought more cherries than Liam. Which could be the amountOf cherries that Harrison brought ?
Answers
The amount of cherries bought by the Harrison is 62.5 pounds.
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.
The amount of cherries bought by the Harrison should be more than the cherries bought by the Liam which is 5/8. Thus, The amount of cherries bought by the Harrison is more than the 5/8 or 62.5 pounds of cherries percent.
The cherries bought by the Liam is 5/8 pounds
The cherries bought by the Harrison is more than the Liam.
As in the problem the number of cherries bought Harrison (let) should be more than the cherries bought by the Liam (let ). Therefore,
H > L
As we know that the number of cherries bought by the Liam is 5/8 pounds. Keep the value of in the above equation, we get,
H > 5/8
This equation can be rewritten in the percentile form as,
h > (5/8) * 100 %
h > (5/2) * 25 %
h > 62.5 %
Hence, The amount of cherries bought by the Harrison is more than 5/8 pounds or 62.5 pounds of cherries percent.

Step-by-step explanation:
(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)
91 rounded to the nearest ten would be 90
94 rounded to the nearest ten would be 90 as well
So, 90 + 90 = 180
Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.
