3x^2+13x+10=0 please help

Answers

Answer 1

Answer: I will use the quadratic equation to solve this:
x= -b +(or minus, both) √b² + 4ac
--------------------------------------------
2a
So, your numbers would be: a = 3
b = 13
c = 10
Then, solve: x = -13 +(or minus, both) √169 + 120
--------------------------------------------------
6
= -13 +(or minus, both) 17
------------------------------------
6
So, first do the plus: -13 + 17
--------------
6
= 2/3
Then do the minus: -13-17
------------
6
= 5

Your answer is: 2/3 and 5

Using only the values given in the table for the function f(x) = –x3 + 4x + 3, what is the largest interval of x-values where the function is increasing?

Answers

Answer:

the largest interval of x values where f(x) is increasing is (-1,1).

Step-by-step explanation:

$f(x)=-x^3+4x+3$

the domain of f(x) is all real numbers.

As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .

Graphically we can also show this that for the x-values in (1,-1) function is increasing.

A share of stock in the Lofty Cheese Company is quoted at 25 1/4. Suppose you hold 30 shares of that stock, which you bought at 20 1/4. If you sell your stock at 25 1/4, which one of the following statements would be true? A: you'll suffer a loss of $15
B: you'll make a profit of $15
C: you'll make a profit of $150
D: you'll suffer a lose if $150

Answers

Since each share was purchased when it was still quoted at 20 1/4, then when the stock value increases, it gains (25 1/4 - 20 1/4) = $5.00 for each stock.Since you're to sell 30 shares of your stock, that means you'll be making a profit of (30 x 5 ) = $150.00.Thus, the answer is C.

The true statement is that you'll make a profit of $150 which is option C.

Given that,

A share of stock in the Lofty Cheese Company is quoted at 25 1/4.

Suppose you hold 30 shares of that stock, which you bought at 20 1/4.

If you sell your stock at 25 1/4, we have to know if they suffer profit or loss and by what amount.

Cost of the stock which you bought is,

Cost = 30 × 20 1/4

= 30 × 20.25

= 607.5

If you sell your stock at 25 1/4,

Selling price = 30 × 25 1/4

= 30 × 25.25

= 757.5

Difference = 757.5 - 607.5

= 150

Hence you have a profit of $150.

A triangular region of the community college parking lot was measured. The measure of the first angle of this triangle is double the measure of the second angle. The measure of the third angle is 19° greater than double the measure of the first angle. What are the measurements of all three angles?

Answers

The key to word problems like this is to turn them into an equation, then they are much simpler to solve.
The first angle is is double the second, so it will be 2x and the second angle will be x. The third angle is 19 more than double the measure of the first angle. that means its 4x +19.
