dexar [7]
You gotta remember that (f-g)(x) means f(x) - g(x).

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

Remer<br> 1) 5k? + 10k + 6 = 0
IceJOKER [234]

Ignoring the "?" in your question:

5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}

If the "?" is a squared symbol that wasn't caught:

5k^2+10k+6=0

Use the quadratic formula

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

to get the solutions:

x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}

as you can see, the discriminant is negative, so the equation has no solution.

identify the initial amount,a,and the growth factor,b,in each exponential function.Break b into (1+r)where r is the rate of grow
Alla [95]

Given function : y=1.05(1.46)^x

We need to identify a " initial amount", b "growth factor", r " rate of growth".

We know, exponential growth formula

y=a(b)^x, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.

y=1.05(1.46)^x ⇔ y=a(b)^x.

We can see a= 1.05 and b = 1.46.

Now, b=1+r.

Therefore, 1+r =1.46.

Subtracting 1 from both sides, we get

1+r-1 =1.46-1

r = 0.46.

On converting 0.46 into percentage, we get

0.46 × 100 = 46.

Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.

The company has a sample box that is a rectangular prism with a rectangular base with an area of 231⁄3 in2. The height of the pr
vodka [1.7K]

Answer:

29.17 in^3

Step-by-step explanation:

We are given that  

Base area of sample box,a=23\frac{1}{3} in^2=\frac{70}{3}in^2

Height of the sample box,h=1\frac{1}{4}=\frac{5}{4} in

We have to find the volume of the sample box.

We know that  

Volume of rectangular prism,V=ah

Where a=Area of base

Using the formula  

Volume of sample box=\frac{70}{3}\times \frac{5}{4}=29.17 in^3

Hence, the volume of the sample box=29.17 in^3
