irakobra [83]3 years ago
8 0

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}

x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}

x = \frac{-5 \pm 7}{4}

x_1 = \frac{-5 + 7}{4}

x_1 = 0.5

x_2 = \frac{-5 - 7}{4}

x_2 = -3

Prove that Tan x + Cos x = 1 /Sin x .Cos x​
Anit [1.1K]

Answer:

tanx + cotx =  \frac{1}{sinxcosx}

Step-by-step explanation:

<u><em>Explanation</em></u>

Take R.H.S   = \frac{1}{sinxcosx}

            =      \frac{sin^{2}x+cos^{2}x  }{sinxcosx}

          =      \frac{sin^{2}x }{sinx cosx} + \frac{cos^{2} x}{sinxcosx}

        = \frac{sinx}{cosx} + \frac{cosx}{sinx}

        = tanx + cotx

tanx + cotx =  \frac{1}{sinxcosx}

My number has a tens digit that is 8 more than the ones digit. Zero is not one of my digits. Write the 2-digit number that match
pochemuha

Answer:

The number is 91

Step-by-step explanation:

Let x be the ones place digit and y be the tens place digit,

Then the number would be 10y + x,

We have,

y - x = 8

Possible values of y and x = { (8, 0), (9, 1) }

∵ 0 is not the digit of the number,

Hence, y = 9 and x = 1

Therefore, required number = 10(9) + 1 = 90 + 1 = 91

The coordinates of three vertices of a triangle are (3, 5), (-1, 5), and (-1, -3). What is the area of the triangle?
Marina86 [1]
If you would graph the triangle, one of the legs would be 8 and another would be 5 and the area of a triangle is bxh/2 so the equation is 8x5/2=20un².
Hope this helped! :)
