Answer:

The answers are respectively 45, 62.5 and 27.5 degrees.

Step-by-step explanation:

According to the given explanation and the formula in the question to calculate the temperatures in a city, the maximum afternoon temperatures for March, August and October respectively are;

March:  For March, x = 3 and cos(\frac{3\pi }{6}) or cos(\frac{\pi }{2}) is equal to 0 so when inserted into the equation we find that t = 45 - 35.0 = 45

August: For August, x = 8 and cos(\frac{8\pi }{6}) is equal to -0.5 so when inserted into the equation we find that t = 45 - 35.(-0.5) = 62.5

October: For October, x = 10 and cos(\frac{10\pi }{6}) is equal to 0.5 so when inserted into the equation we find that t = 45 - 35.(0.5) = 27.5

I hope this answer helps.

Sam kicks a soccer ball from the ground. The height of
Alexeev081 [22]

Answer:

The ball will take 2.6 seconds to hit the ground again.

Step-by-step explanation:

Sam kicks a soccer ball from the ground. The height of  the ball (in feet) can be modeled with the function,  h(t) = −16t(t − 2.6), where t is the time in seconds  after the ball is kicked.

So, the ball will be at ground when h = 0 = - 16t(t - 2.6)

⇒ t = 0 or t = 2.6.

Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)

Lin and Priya were working on solving this system of equations.
garri49 [273]

Answer:

we can conclude two things that:

  1. If we multiple the two sides of any given equation by the same factor, we would get an equivalent equation, which will have the same solution as the original solution.
  2. Either person's move will work. Lin's move eliminated the x variable, while Priya's eliminated y variable, but in the end the solution was same.

Step-by-step explanation:

<em>Why either move creates a new equation with the same solutions as the original equation?</em>

If we multiple the two sides of any given equation by the same factor, we would get an equivalent equation, which will have the same solution as the original solution.

When we multiple the two sides of any given equation by the same number, it would keep the two sides of that particular equation equal. So, whatever the  the solution the first equation may get, will still work for the second equation.

<em>Determining Lin's first move i.e. to multiply the first equation by 3.</em>

Let us consider the equation

x/3 + 2y = 4      .....[1]

x + y = -3           .....[2]

Lin's first move is to multiply the first equation by 3.

3(x/3 + 2y) = 3(4 )

x + 6y = 12         .....[3]

Now subtract the Equation [2] from Equation [3]

x + 6y - x - y = 12 - (-3)

5y = 15

y = 3

Putting y = 3 in [2]

x + (3) = -3

x = -6

So, x = -6 and y = 3

<em>Determining Priya's first move i.e. to multiply the Second equation by 2.</em>

Let us consider the equation

x/3 + 2y = 4      .....[1]

x + y = -3           .....[2]

Priya's first move is to multiply the second equation by 2.

2(x + y) = 2(-3)          

2x + 2y = -6           .....[3]

Now subtract the Equation [2] from [1]

x/3 + 2y - 2x - 2y= 4 - (-6)

x/3 - 2x = 10

x - 6x = 30

x = -6

Putting x = -6 in Equation [2]

x + y = -3

-6 + y = -3

y = 3

So, x = -6 and y = 3

So, from the entire analysis, we can conclude two things that:

  1. If we multiple the two sides of any given equation by the same factor, we would get an equivalent equation, which will have the same solution as the original solution.
  2. Either person's move will work. Lin's move eliminated the x variable, while Priya's eliminated y variable, but in the end the solution was same.

Write the equation of the line in slope-intercept form.
Alex Ar [27]
The answer is B.
Slope-intercept line is written as:
y=mx+b
m=slope
b=y-intercept
4 is the y-intercept because the line crosses the y-axis at 4.
The slope is -2 over 5, because slope is written as y over x.
So, if you start at the point at the 4, count 2 spaces down and 5 spaces right. The line crosses the point exactly, which is how you know the slope is accurate.
