Answer:

$2.75

Step-by-step explanation:

Since x represents the number of years since 1980 to 2000 that means the ticket prices increase by 0.10 (or 10 cents) each year. This means the base price in 1980 was $2.75. To prove it, we would plug in the correct information into the expression. The number of years since 1980 would be 0 so we would plug in 0 for x. 2.75 + 0.10(0) = $2.75.

Answer:

A

Step-by-step explanation:

By the geometric mean theorem, 21/20=20/a -> 400/21.

And by the Pythagorean theorem,

[tex]b = \sqrt{(21 + \frac{400}{21}) - {29}^{2} } = \frac{580}{21} [/tex]

Answer:

2nd option

Step-by-step explanation:

using the cosine and sine ratios in the right triangle and the exact values

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] and sin30° = [tex]\frac{1}{2}[/tex] , then

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{12\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 12[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 36 ( divide both sides by 2 )

x = 18

and

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{12\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

y = 6[tex]\sqrt{3}[/tex]

We need a acceleration time graph (Attached)

So when t is 0

Find y intercept by observing the point where the line crosses y axis

Now the particle is given moving along x axis means on the x axis

So acceleration remains 0 as on x axis y intercept is 0 always

Answer:

The graph is a function of absolute value.

This means that for each value of f (x) there are two possible values of x.

The absolute value function is:

f (x) = lxl

y = f (x) - 2 shifts the graph 2 units down.

y = f (x + 3) moves the graph 3 units to the right.

Finally:

The function that best fits this graph is:

f (x) = l-x + 3l-2

Step-by-step explanation:

From the graph it is evident that it is the graph of the absolute value of the function i.e. f(x) = |x| and we know that 'Translation' is a transformation that shifts the graph of a function in any direction.

Now, as we can see that the graph is shifted towards the right of the y-axis at point x=3, this means that it is translated by 3 units to the right of y-axis.

Therefore, the function becomes f(x) = |x-3|.

Furthermore, it is also shifted downwards at the point x= -2, this means that it is translated by 2 units downward from the x-axis.

Hence, the new function is f(x) = |x-3| - 2.

=======================================================

Explanation:

Let's consider the number 39

We have 2 nonzero digits here, so we have 2 significant figures (sig fig for short).

The goal is to round this to one sig fig instead of two. The question is: do we keep the 3 or keep the 9 instead?

The answer is that we keep the 3 and toss the 9, but the 9 will mean we bump the 3 up to 4.

So 39 bumps up to 40 where the 0 is not a sig fig (review the many sig fig rules about how to deal with zeros). The zero is just a placeholder to help determine the magnitude of the number.

In other words, 39 is closest to 40 rather than 30. We can think of "40" as "4 tens" and even drop the unit "tens" to focus solely on that 4. It would be implied we're talking about the tens unit from then on. You hopefully agree at this point we definitely have one sig fig to focus on.

----------------

If we repeated the last set of steps for the number 38, then it also rounds to 40 when rounding to one sig fig. The same goes for 37, 36, and 35.

The values 35, 36, 37, 38, 39 all round to 40 when rounding to one sig fig.

Doing the same type of logic, but on the upper side of 40, we have the values {41,42,43,44} also rounding to 40. The value 45 won't work because it rounds to 50 instead.

Therefore, x can be any of the following integers:

35,36,37,38,39,40,41,42,43,44

and they all round to 40 when rounding to one sig fig.

--------------

The last step is to divide the smallest item of the last list mentioned over the largest item

35/44

The numerator and denominator have no factors in common other than 1. So the fraction cannot be further reduced.

5)

5x⁴-4x³-3x-4+2x⁴+6x³-2x

7x⁴+2x³-5x-4

Just do the simple addition. Make sure to add like terms. For instance: Add 3x² with 2x² only, not with 3x and 2.

→ 2x² + 3x + 2 + 3x² - 5x - 1

→ 2x² + 3x² + 3x - 5x + 2 - 1

The law of subtraction is to subtract the smaller value from the larger value. But it is not necessary that it is always applicable. Its value can be positive, negative and zero (which varies with the given values).

→ x² - 4 - (12x² + 4x - 6)

There will be no change in sign during addition. But if you're doing subtraction change the signs.

→ x² - 4 - 12x² - 4x + 6 [ Product of (-)(-) is (+) and (+)(-) is (-) ]

→ x² - 12x² - 4x - 4 + 6

→ 6x² + 3x - 4 + x² - 7

→ 6x² + x² + 3x - 4 - 7

→ 7x³ + 4x - 1 + 2x² - 6x + 2

→ 7x³ + 2x² + 4x - 6x - 1 + 2

→ 5x⁴ - 4x³ - 3x - 4 - (-2x⁴ - 6x³ + 2x)

→ 5x⁴ - 4x³ - 3x - 4 + 2x⁴ + 6x³ - 2x

→ 5x⁴ + 2x⁴ - 4x³ + 6x³ - 3x - 2x - 4

The value of the function for the other factors will be -1.41  and - 3.90 respectively.

It is a method for dividing a polynomial into parts, each of which will be multiplied. At this moment, the polynomial's value will be zero.

Given function;

f(x) =2x⁴ - 2x-5

The roots (zeros) are the

x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

x≈−1.089744,1.40581409

The value of the function for the other factors;

f(x) =2x⁴ - 2x-5

f(−1.089744) = 2(−1.089744)⁴-2(1.089744)-5

f(−1.089744) = -1.41

f(x) =2x⁴ - 2x-5

f(1.40581409) = 2(1.40581409)⁴-2(1.40581409)-5

f(−1.089744) = - 3.90

The value of the function for the other factors will be -1.41 and - 3.90 respectively.

Answer:

127 degrees

Step-by-step explanation:

Angles in a triangle add up to 180

180 - 44 - 83 = 53

Angles on a straight line add up to 180

180 - 53 = 127

Answer:

im not really sure but x may be 127 degrees?

Step-by-step explanation:

so i dont really remember but a triangle is 180 degrees

to find x we must find the value in the triangle. lets say y

y + 44 + 83 = 180

y + 128 = 180

y = 180 - 127

y = 53

the angle in the triangle is 53 degrees. so a line is...also 180 degrees... um so we do

x + 53 = 180

x = 127

Answer:

Angle B measures 116 degrees

Step-by-step explanation:

Because all the angles of a triangle add up to 180 degrees.

28 degrees + 36 degrees = 64 degrees

180 degrees - 64 degrees = 116 degrees

Answer:

116

Step-by-step explanation:

The sum of all the angles in a triangle will equal 180 degrees. SO, to find the missing angle, we have to add the two known angles together and subtract that from 180.

28 + 36 = 64

180 - 64 = 116

Therefore, the measure of the missing angle is 116 degrees.
