Hey. Let me help you out

First, let's rewrite the equation in order to minimize confusion. The way you wrote it makes it hard to vision it.

$7d^2+10d=3$

Now, we just replace the variable d with a value we have.

$7(3^2)+10$

Three to the power of two is going to equal to 9.

$7*9+10$

Seven times nine is 63.

$63+10$

Finally, 63 plus 10 is going to be 73.

Answer is 73

Consider the following proability density function: f(x) = { kx. 0<= x< 2, k(4-x). 2<= x <=4, 0. otherwise. find the

Gnesinka [82]

The value of K for which f(x) is a valid probability density function is 1/4.

<h3>How to solve for the value of K</h3>

$\int\limits^4_0 {fx(x)} \, dx =1$

$\int\limits^2_0 {Kx} \, dx +\int\limits^4_2 {K(4-x)} \, dx =1$

$K[\frac{2^2}{2} -0]+[K[4(4-2)-(\frac{4^2}{2} -\frac{2^2}{2} )]=1$

open the equation

$K\frac{4}{2}+K[8 - (\frac{16}{2} -\frac{4}{2} )] = 1\\$

$2K+K[\frac{4}{2} ]=1$

2K + 2K = 1

4K = 1

divide through by 4

K = 1/4

The tax rate is 3.9%<br> What is the tax on 42$? <br> Round to the nearest hundredth

mafiozo [28]

To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64
