liq [111]3 years ago
7 0

Answer:

The answer is B

Step-by-step explanation:

f(x) = 4x² + 1

g(x) = x² - 5

(f-g)(x) = 4x² + 1 - (x²-5)

= 4x² + 1 - x² + 5

= 3x² + 6

bearing in mind that an absolute value expression is in effect a piece-wise expression, because it has a ± version.

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for
vivado [14]

Answer:

The equation to represent the rate of receding water level is                     L = 34 (0.5)^{d}   .

Step-by-step explanation:

Given as :

The initial level of water in river = 34 feet

The rate of receding water level = 0.5 foot per day

Or, The rate of percentage of receding water level = 50 % per day

Let the level of water after d days = L

Now,

The level of water after d days = initial level of water × ( (1-\dfrac{\textrm Rate}{100})^{Time}

I.e L = 34 × ( (1-\dfrac{\textrm 50}{100})^{d}

∴  L = 34 × (0.5)^{d}

Hence The equation to represent the rate of receding water level is                L = 34 (0.5)^{d}   . Answer

The sum of three consecutive numbers is 46. Find the
Citrus2011 [14]

Let the three consecutive number be x,x+1 and x+2.

It is given sum of three consecutive numbers is 46.

So,x+x+1+x+2=46

3x+3=46.

Subtracting 3 both sides

3x=46-3

3x=43.

x= \frac{43}{3}.

Since \frac{43}{3}. is not an integer there is no true answer to this problem.
