Answer:

C and B.

Step-by-step explanation:

f(x) = 4 - x^2.

The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.

f(x) = 2^x + 5.

Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.

3. A man needed money for college. He borrowed $6,000 at 14% simple interest per year. If he paid $420 interest, what was the du

9966 [12]

Answer: half year

Step-by-step explanation:

The formula to find the simple interest is given by :-

$I=Prt$ , , where P is the principal amount , r is the rate of interest and t is the time in year.

Given : I=420 ; r=14%=0.14 and P =$6000

Then, we have the following equation :-

$420=6000\times0.14 \times t\\\\\Rightarrow\ t=\dfrac{420}{6000\times0.14}=0.5$

It means the duration of the loan is half year .

How tall is the tree? 5ft 35° -20ft- [? ]ft

SVEN [57.7K]

Answer:

$\boxed{\bf 19ft}$

Step-by-step explanation:

$\bf tan\:\theta =\cfrac{opp}{adj}$

$\bf tan(35^o)=\cfrac{x}{20}$

$\bf 20\;tan (35^o)=x$

$\bf 14ft=x$

The height of the tree:-

$\bf x+5ft$

$\bf 14ft+5ft$

$\bf 19ft$
