Answer:

-1.28 AND 2.61

Step-by-step explanation:

$10= -4x+3x^2\\ 3x^2 -4x - 10 = 0\\\\$

use quadratic formula

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

Solution/X-Intercepts: -1.28 AND 2.61

Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new mat

likoan [24]

F+G:

$F+G=\begin{bmatrix}{-1.8} & {-8.6} & {} \\ {2.85} & {-1.4} & {} \\ {-1.8} & {5.1} & {}\end{bmatrix}+\begin{bmatrix}{1.32} & {-1.9} & {} \\ {2.25} & {0.0} & {} \\ {-6.2} & {1.4} & {}\end{bmatrix}$

Then, add the elements that occupy the same position:

$H=\begin{bmatrix}{-1.8+1.32} & {-8.6+(-1.9)} & {} \\ {2.85+2.25} & {-1.4+0.0} & {} \\ {-1.8+(-6.2)} & {5.1+1.4} & {}\end{bmatrix}$

Solve

$H=\begin{bmatrix}{-0.48} & {-10.5} & {} \\ {5.1} & {-1.4} & {} \\ {-8} & {6.5} & {}\end{bmatrix}$

So, we find the element at address h31:

$H=\begin{bmatrix}{h11} & {h12} & {} \\ {h21} & {h22} & {} \\ {h31} & {h32} & {}\end{bmatrix}$

In this case, position h31 is - 8.0

Brian flips a fair coin 3 times.<br> What is the probability of getting 3 tails?

Sliva [168]

Answer:

the answer is one over eight

the formula says required outcome divided by sample space

the sample space here is it because we have three coins and the Three coins have two faces each so it becomes 2 x 2 * 2 that is 8 and that is the total sample space we are supposed to get the probability of getting 3 tails and for each coin you have 1/2 x 1/2 x 1/2 and that is 1/8 as your final answer and do probability of getting three tails

The dance committee hired a DJ for the fall dance. The DJ charges

boyakko [2]

Answer: 4 hours

Step-by-step explanation:

4 Hours

Explanation:

Make h = hours

You add the $55 extra cost for the assistant

$125h + $55 = $555

Use additive inverse to isolate the term with the variable

$125h + $55 - $55 = $555 - $55

Use multiplicative inverse to isolate the variable

$\frac{125h}{125}$ = $\frac{500}{125}$

Hours would be: 4 Hours.

I hope this helps! Please mark brainliest.
