Answer:

Step-by-step explanation:

The zeros are the x-values where the graph crosses the x-axis (y=0; That's why it is called a "zero.") The graph crosses y=0 at x=1 and x=3.

A factor of the polynomial is zero at each zero. Hence the factorization is ...

  y = (x -1)(x -3)

The first factor is zero at x=1; the second factor is zero at x=3.

Answer:

∠A ≈ 58.1°

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for ∠A

tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{8.2}{5.1}[/tex], hence

A = [tex]tan^{-1}[/tex] ( [tex]\frac{8.2}{5.1}[/tex] ) ≈ 58.1°

Answer:

Answer:

4280 passes were sold

Step-by-step explanation:

The unknown we are looking for the number of passes that were sold.  We don't know how MANY were sold, but we do know that the cost of ONE is 12.50.  We represent the number of passes at that price per pass as

12.50x

We also know that money earned from the sale of this unknown number of passes came to 53,500.  Our equation then becomes

12.50x = 53,500

Solving for x, we divide both sides by 12.50 to get that

x = 4280

Final answer:

To find the number of annual visitor passes sold at Woodland Mound Park, divide the total sales ($53,500) by the price per pass ($12.50), resulting in 4,280 passes sold.

Explanation:

The question asks how many annual visitor passes were sold at Woodland Mound Park last year if each pass costs $12.50 and the total amount raised from pass sales was $53,500. To find the number of passes sold, you'll need to divide the total sales by the price per pass. Here is the step-by-step calculation:

Answer:

f(x) = 4|x|

Step-by-step explanation:

the graph of f(x) = |x|, looks like a "V"

if we want to make the graph "narrower", what we are doing is really trying to make the slope steeper (i.e more vertical) so that the opening of graph at the top of the "V" becomes smaller.

in order the make the slope steeper, we have to multiply the x-term of the function (in this case |x|) by any factor that is greater than 1. (multiplying by factors smaller than 1 will make the slope more gentle and hence making the "V" wider).

The only choice that shows the original function multiplied by a number that is greater than 1 is f(x) = 4|x|

Explanation:

A triangle can be formed for b=3 and B=15° as long as side c is between 3 and 3/sin(15°) ≈ 11.59 inches in length. The limit for side c on the high end is that it is opposite a right angle. The limit for side c on the other end is that it is opposite a linear angle.

For the given length of side c, there are two possible triangles with b=3 and B=15°. (See attached.)

_____

For the given values of b and c, the largest possible value of B is the angle that puts side c opposite a right angle: B ≤ arcsin(3/7) ≈ 25.3769°

An infinite geometric series with a common ratio greater than 1 does not converge to a sum. The series is divergent.

Answer:

Sin x = a / b.

Step-by-step explanation:

The opposite side =a and the adjacent side = 4 (because tan x = a/4.

Cos x = 4/b so the hypotenuse = b ( because  Cos = adjacent /hypotenuse.

So sin x = opposite /hypotenuse = a / b.

Answer:

  y = -1/2x +5

Step-by-step explanation:

Slope-intercept form is ...

  y = mx + b

Matching this to the equation you have, you see that ...

  m = -2/4 = -1/2

  b = 5

The equation is already in slope-intercept form. The fraction that is the slope can be reduced, but that is not essential to the form.

B) The estimated animal population in 2050, given the same percent increase from 1950 to 2000, will be approximately 8,100.

The percent increase from 1950 to 2000 =  (New Population - Original Population) / Original Population x 100%

In this case, it is:

(7200 - 6400) / 6400 x 100%

= 12.5%

The population in 2050 under the same percent increase, we apply this percentage to the population in 2000:

7200 x (1 + 12.5/100) = 7200 x 1.125 = 8100

The expected population in 2050 is 8,100.

Thus, the correct answer is B) 8,100.

To calculate the percent increase over 50 years, we first find the absolute increase from 1950 to 2000, and then determine the percent increase relative to the initial value in 1950.

Next, we apply that percent increase to the population in 2000 to predict the population in 2050.

Calculate the Absolute Increase

The increase in the animal population from 1950 to 2000 is:

[tex]\[7200 - 6400 = 800.\][/tex]

Calculate the Percent Increase

To find the percent increase over the period from 1950 to 2000, use the following formula:

[tex]\[ \frac{{\text{increase}}}{{\text{initial value}}} \times 100 = \frac{{800}}{{6400}} \times 100 = 12.5\%. \][/tex]

Thus, the population increased by 12.5% over 50 years.

Apply the Percent Increase to Predict the 2050 Population

Given the 12.5% increase, the expected increase in population from 2000 to 2050 would be 12.5% of 7200:

[tex]\[ 0.125 \times 7200 = 900. \][/tex]

Thus, the predicted population in 2050 is:

7200 + 900 = 8100.

Question :

In 1950, scientists estimated a certain animal population in a particular geographical area to be 6,400. In 2000, the population had risen to 7,200. If the animal population experiences the same percent increase over the next 50 years, what will the approximate population be?

A) 8,000

B) 8,100

C) 8.400

D) 8.600

The square had a side length of 3x+13.

Because the perimeter is 12x+52, you have to divide that by each of the four sides.

[tex]m\angle2+m\angle3=m\angle5\ and\ m\angle2=25,\ then\ 25+m\angle3=m\anlg5[/tex]

Insert 25 instead of m<2 into the equation

Answer:

25 + m∠3 = m∠5

Step-by-step explanation:

Substitution property of equality states that,

If a + b = c and b = e ⇒ a + e = c

Given,

[tex]m\angle 2 + m\angle 3 = m\angle 5[/tex] and [tex]m\angle 2 = 25[/tex]

By substituting the value of m∠2 in first equation,

[tex]25 + m\angle 3 = m\angle 5[/tex]

Hence, the missing terms is '25 + m∠3'

  The appropriate expression is ...

     90,000(1+0.006)^72+708.61[(1-(1+0.006)^72)/0.006] . . . best matches C

Step-by-step explanation:

The formula used to calculate the remaining balance is ...

  A = P(1 +r)^n +p((1 -(1 +r)^n)/r) . . . . . note the parentheses on the fraction numerator

In this formula, r is the monthly interest rate: 7.2%/12 = 0.006, and n is the number of monthly payments: 6×12 = 72. Putting these values into the formula along with the loan amount (P=90,000) and the payment amount (p=708.61) gives ...

  A = 90,000(1.006)^72 +708.61((1 -(1.006)^72)/0.006)

  A = 74,871.52

Step-by-step explanation:

Answer:

(1, -5); (4, 3)

Step-by-step explanation:

We generally orient maps with north at the top. This problem presumes that orientation along with a grid having units of 1 mile. "Town Center" is taken to be the origin of the grid. As is usually the case, left/right coordinates are indicated first in an ordered pair, with up/down coordinates being indicated second.

Then the warehouse location 8 miles south and 3 miles west of Town Center is considered to have coordinates of (-3, -8). Movement 3 miles north and 4 miles east is considered to be translation by (4, 3). This translation vector is the answer to the second part of the problem.

The answer to the first part of the problem is the sum of the starting position and the translation:

(-3, -8) +(4, 3) = (1, -5)

The truck's final position is (1, -5). The translation vector to get it there is (4, 3).

Answer:

[tex] -4 \sqrt{5} [/tex]

Step-by-step explanation:

Quadrant 2 means cosine is negative.

So [tex] \sin(\theta)=\frac{2}{3} =\frac{\text{ opp }}{\text{ hyp }} [/tex]

So the adjacent side is [tex] \sqrt{3^2-2^2}=\sqrt{9-4}=\sqrt{5} [/tex]

So [tex] \cos(\theta)=-\frac{\sqrt{5}}{3} [/tex]

Now to find [tex] \tan(2 \theta) [/tex]

[tex] \tan(2 \theta) =\frac{2\tan(\theta)}{1-\tan^2(\theta)}[/tex]

We will need [tex] \tan(\theta) [/tex] before proceeding.

[tex] \tan(\theta) =\frac{\sin(\theta)}{\cos(\theta)}=\frac{\frac{2}{3}}{\frac{-\sqrt{5}}{3}}=\frac{-2}{\sqrt{5} } [/tex]

Now plug it in and the rest is algebra.

[tex] \tan(2 \theta) =\frac{2\tan(\theta)}{1-\tan^2(\theta)} =\frac{2 (\frac{-2}{\sqrt{5}}}{1-\frac{4}{5}} [/tex]

Now the algebra, the simplifying.... We need to get rid of the compound fraction.  We will multiply top and bottom by [tex] 5 \sqrt{5} [/tex]

This will give us

[tex] \frac{-4(5)}{5 \sqrt{5}-4 \sqrt{5}} [/tex]

[tex] \frac{-20}{\sqrt{5}} [/tex]

Multiply top and bottom by [tex] \sqrt{5} [/tex]

[tex] \frac{-20 \sqrt{5}}{5} [/tex]

The answer reduces to

[tex] -4 \sqrt{5} [/tex]

Final answer:

To find tan2θ when sinθ = 2/3 and θ is in Quadrant II, we use the Pythagorean identity to find cosθ and the double angle identity for tangent. After calculation, tan2θ = -4√5.

Explanation:

If sinθ = 2/3 and θ is located in Quadrant II, we first have to find cosθ and then use the double angle identity for tangent to find tan2θ. Since sinθ is positive in Quadrant II and cosθ must be negative (as the x-values are negative in Quadrant II), we can use the Pythagorean identity sin2θ + cos2θ = 1 to find cosθ. Thus, cosθ = -√(1 - sin2θ) = -√(1 - (2/3)2) = -√(1 - 4/9) = -√(5/9) = -√5/3.

The double angle identity for tangent is tan2θ = 2tanθ / (1 - tan2θ). But first, we find tanθ = sinθ/cosθ = (2/3) / (-√5/3) = -2/√5. Then, tan2θ = 2(-2/√5) / (1 - (-2/√5)2) = -4/√5 / (1 - 4/5) = -4/√5 / (1/5) = -20/√5. Simplifying further, we multiply by √5/√5 to rationalize the denominator, which gives us tan2θ = -20√5/5 = -4√5.

Answer:

h^-1(x) = (5x - 6)/2

Step-by-step explanation:

To find the inverse of h(x) = (2x + 6)/5, we need to solve for 'x':

y = (2x + 6)/5 ⇒ 5y = 2x + 6 ⇒ 5y - 6 = 2x ⇒ x = (5y - 6)/2

Therefore, h^-1(x) = (5x - 6)/2

Answer:

(5x-6)/2

Step-by-step explanation:

h(x) = (2x + 6)/5

y =  (2x + 6)/5

To find the inverse, exchange x and y

x = (2y+6) /5

Then solve for y

Multiply each side by 5

5x = (2y+6)/5*5

5x = 2y+6

Subtract 6 from each side

5x-6 = 2y+6-6

5x-6 = 2y

Divide by 2

(5x-6)/2 = 2y/2

The inverse is

(5x-6)/2
