Answer:

x = 8.6 cm

Step-by-step explanation:

To find x, we need to take the sin ratio of the 35° angle.

Identity

sin∠x = opposing side length / length of hypotenuse

Solving

sin35° = 0.57
sin35° = x/15
⇒ x/15 = 0.57
⇒ x = 15 × 0.57
⇒ x = 8.55 cm
⇒ x = 8.6 cm

Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent. How many text messag

professor190 [17]

Given that Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent.

Kimora's cell phone bill for one month is $52.

We need to determine the number of text messages Kimora sent for one month.

Also, we need to write and equation and solve it.

The equation:

Let x denote the number of text messages Kimora sent for one month.

Thus, the equation is given by

$35+0.05x=52$

Therefore, the equation for the number of text messages Kimora sent for one month is $35+0.05x=52$

Solving the equation:

We need to solve the equation $35+0.05x=52$

Subtracting both sides of the equation by 35, we get;

$0.05x=17$

Dividing both sides of the equation by 0.05, we get;

$x=340$

Therefore, the number of messages sent is 340.

What's the inverse of a 2x4 matrix?

balandron [24]

Mxn Matrices do not have an inverse solution for m ≠ n, so your 2x4 will not have a solution.

Generally, inverting matrices is done through finding the determinant of the square matrix and then performing an operation on the matrix based on the size of the matrix. 

Wikipedia has a good article on Matrix inversion, take a look there for more information.
