Answer:

Step-by-step explanation:

Part b:  Find the length of the sidewalk.  The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3.  Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:

cos 30° = adj / hyp, or:

  √3       2√3

 ------- = --------

     2        hyp

This simplifies to

     1          2

 -------- = -------

      2        hyp

Cross multiplying results in:  hyp = 4.  The sidewalk length is 4 miles.

a.  The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:

                               1       opposite side

sin 30 degrees = ----- = -------------------------   or 2(opp side) = 4.

                               2                 4

Then the opp side, which is the width of the park, is 2.

Answer:

A. 10 ft

Step-by-step explanation:

Since dimensions of the wall are similar to the dimensions of the window.

Therefore, lengths and widths of wall and window would be in proportion.

So,

[tex] \frac{h}{2} = \frac{24.5}{4.9} \\ \\ h = \frac{24.5 \times 2}{4.9} \\ \\ h = \frac{49}{4.9} \\ \\ h = \frac{490}{49} \\ \\ h = 10 \: ft[/tex]

Step-by-step explanation: -8 - - 158= 5

=>5m=150

=>m=30

Step-by-step explanation:

1. Rearrange term

-158=-8-5m

-158=-5m -8

2. Add 8 to both sides of the equation

-158=-5m -8

-158+8=-5m -8=8

3. Simplify

-158+8=−5m−8+8

−150=−5m-8+8

−150=−5m−8+8

−150=−5m

4. Divide both sides of the equation by the same term

−150=−5m

−150=−5m

-5         -5

5. Simplify

Step-by-step explanation:

f (15) = $142.50

i hope this help you!

We know that:

Harrison gets $9.50 per hour of work.

He can work a maximum of 15 hours per week.

He needs to earn a minimum of $28.50 per week.

A) We want a function f(h) that tells how much he wins in a week if he works h hours.

So we know that he gets $9.50 per hour of work, then if he works h hours, he gets h times $9.50, then we can just write:

f(h) = $9.50×h

B) First remember that the domain is the set of possible values of h, and the range is the set of possible values of f(h).

We know that the maximum value of h is 15, to find the minimum value of h we need to use the other restriction, that he needs to win at least $28.50, then we need to solve:

$9.50×h = $28.50

h = ($28.50)/($9.50) = 3

Then we can conclude that the domain is:

D = [3, 15]

To find the range, we just need to evaluate the function in the minimum and maximum values of the domain:

f(3) = $28.50

f(15) = $142.50

Then the range is:

R = [$28.50, $142.50]

Answer:

0.2 is 8% of 2.5

Step-by-step explanation:

question: what percent of 2.5 is 0.2

paraphrased: 0.2 is what fraction of 2.5 (then convert to percent)

make into fraction

0.2/2.5

=2/25

therefore 0.2 is 2/25ths of 2.5  !

to convert to percentage, make the denominator /100

2/25

multiply by 4 both sides

= 8/100

8 out of 100 is 8%

=8%

Answer:

x^4-3x^3+x^2-4

Step-by-step explanation:

Given the following functions

R(x) = 2x^4 – 3x^3 + 2x – 1 and

C(x) = x^4 – x^2 + 2x + 3

We are to find the profit function P(x)

P(x) = R(x) - C(x)

P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)

P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3

Collect the like terms

P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3

P(x) = x^4-3x^3+x^2+0-4

P(x) = x^4-3x^3+x^2-4

Hence the required profit function P(x) is x^4-3x^3+x^2-4

Answer: -5

Step-by-step explanation:

The value of negative zero in g(x) = 3x² + 14x - 5 is 1.

Descarte's rule for no. of at most positive real roots in a polynomial is the no. of sign changes in the polynomial.

Descarte's rule for no. of at most negative real roots in a polynomial f(x) is the number of sign changes in f(-x).

All the other left over roots are imaginary and come in conjugate pairs.

The number of negative of f is equal to the number of sign changes of successive terms of f(-x).

Given, g(x) = 3x² + 14x - 5.

Now, g(-x) = 3(-x)² + 14(-x) - 5.

g(-x) = 3x² - 14x - 5.

The signs are +, -, - so only one sign changes.
