Answer:

x = -5.83, -0.17

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Since we are given <em>a</em> = 1, <em>b </em>= 6, and <em>c</em> = 1 from our quadratic, we use the Quadratic Formula:

Step 1: Plug in variables

$x=\frac{-6+/-\sqrt{6^2-4(1)(1)} }{2(1)}$

Step 2: Solve

$x=\frac{-6+/-\sqrt{36-4} }{2}$

$x=\frac{-6+/-\sqrt{32} }{2}$

Step 3: Evaluate to decimals

When you do so, you should get x = -5.82843 and -0.171573

Trig questions above solve for x and round to the nearest tenth

Alik [6]

Answer:

x= 51.3

x=35.1

Step-by-step explanation:

10.)

For this one we have the adjacent side and the hypotonouse

Which means we'll use CAH

cos(x)=25/40

x= 51.31781255

(assuming that we have to round to the nearest tenth again)

x=51.3

12.)

For this one we have the adjacent and hyptonouse

we'll use CAH again

cos(x)=27/33

x= 35.09680123

x=35.1

Question 2 of 5

jeka57 [31]

The number of solutions in each equation are as follows:

1 solution: 4^x = 2^{-x}
2 solution: 3/2x + 2 = 2^{x} + 1 and 3x + 1 = 2^{-x}.
No solution: 4^x + 2 = 3^x - 1 and 2x - 5 = 3^{x} + 2.

<h3>How to determine the number of solutions?</h3>

In order to determine the number of solutions, we would split the single equation to two different equations and then plot a graph, so as to reveal their solutions.

This ultimately implies that, the number of solutions is equal to the point of intersection between the lines of the equations plotted on a graph.

In conclusion, the number of solutions in each equation are as follows:
