Answer:

<u>Parent function</u>

f(x)=\log_2(x)

Since we cannot take logs of zero or negative numbers, the domain is (0, \infty) and there is a vertical asymptote at x=0.

There are no horizontal asymptotes and the range is (- \infty,\infty).

The end behaviors of the parent function are:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow - \infty

\textsf{As } x \rightarrow \infty, f(x) \rightarrow \infty

To determine the attributes of the given function, compare the given function with the parent function.

<u>Given function</u>

<u />f(x)=- \log_2(x)+5

The given function is <u>reflected in the x-axis</u>.  Therefore, the end behaviors are a reflection of those of the parent function:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow \infty

\textsf{As } x \rightarrow \infty, f(x) \rightarrow - \infty

As the given function is <u>translated vertically</u> (5 units up) only, the domain, range and asymptote will not change, since the function has not been translated horizontally.

\textsf{Domain}: \quad (0, \infty)

\textsf{Range}: \quad (- \infty, \infty)

\textsf{Asymptote}: \quad x=0

<u>Conclusion</u>

The function f(x) is a \boxed{\sf logarithmic}} function with a \boxed{\sf vertical}} asymptote of \boxed{x = 0}.  

The range of the function is \boxed{(- \infty, \infty)}, and it is \boxed{\sf decreasing} on its domain of \boxed{(0, \infty)}.  

The end behavior on the LEFT side is as \boxed{x \rightarrow 0^+}, \boxed{f(x) \rightarrow \infty}, and the end behavior of the RIGHT side is \boxed{x \rightarrow \infty}, \boxed{f(x) \rightarrow -\infty}.

Answer:

The required answer is c=7\sqrt{3}

Therefore the number in green box should be 7.

Step-by-step explanation:

Given:

AB = 7√2

AD = a , BD = b , DC = c , AC = d

∠B = 45°, ∠C = 30°

To Find:

c = ?

Solution:

In Right Angle Triangle ABD Sine identity we have

\sin B = \dfrac{\textrm{side opposite to angle B}}{Hypotenuse}\\

Substituting the values we get

\sin 45 = \dfrac{AD}{AB}= \dfrac{a}{7\sqrt{2}}

\dfrac{1}{\sqrt{2}}= \dfrac{a}{7\sqrt{2}}\\\\\therefore a=7

Now in Triangle ADC Tangent identity we have

\tan C = \dfrac{\textrm{side opposite to angle C}}{\textrm{side adjacent to angle C}}

Substituting the values we get

\tan 30 = \dfrac{AD}{DC}= \dfrac{a}{c}\\\\\dfrac{1}{\sqrt{3}}=\dfrac{7}{c}\\\\\therefore c=7\sqrt{3}

The required answer is c=7\sqrt{3}

Henrietta buys twelve pounds of bananas and ten pounds of apples for $ 12 . Gustavo buys eight pounds of bananas and five pounds
Olegator [25]

Answer:

The price per pound of bananas is $0.5 and the price per pound of apples is $0.6

Step-by-step explanation:

Let

x -----> the price per pound of bananas

y -----> the price per pound of apples

we know that

12x+10y=12 -----> equation A

8x+5y=7 ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

The intersection point is (0.5,0.6)

see the attached figure

therefore

The price per pound of bananas is $0.5

The price per pound of apples is $0.6

Please help!! It's extra credit work, I'm on Spring break, and I'm tring to be on honor roll!!
Reika [66]

Answer: C

Explanation:

Since tan(H) equals 1, we can conclude that angle H equals 45 degrees. Therefore, we know that it is a 45-45-90 triangle. Therefore, since both legs are equal, sin or cos doesn’t matter. Therefore, C is correct. (Draw it for yourself, it helps)
