Use the discriminant to find the number of real solutions of the equation 3x^2 – 5x + 4 = 0

Virty [35]

To use the discriminant, first identify a, b, and c. In your equation a= 3 b = -5 and c = 4. Now plug into the discriminant b^2 - 4ac. Substituting yields (-5)^2 - 4(3)(4). Simplifying, 25 - 48 = -23. Since the discriminant has a negative value, there is no real solution to this equation.

PLEASE HELP! The formula F = 95C + 32, where C stands for temperature in degrees Celsius, is used to convert Celsius to Fahrenhe

Masteriza [31]

The temperature is 86°F when the temperature is 30°C.

Step-by-step explanation:

Formula for Celsius to Fahrenheit;

F = $F=\frac{9}{5}C+32$

Where C stands for temperature in degrees Celsius.

Given,

Temperature in Celsius = 30 degrees

Temperature in Fahrenheit = $\frac{9}{5}*30+32$

Temperature in Fahrenheit = $9*6+32$

Temperature in Fahrenheit = $54+32 = 86\ degrees\ Fahrenheit$

The temperature is 86°F when the temperature is 30°C.

Please help me <br> I have to solve the triangle with the law of sines

Nikitich [7]

Check the picture below.

and since a triangle has a sum of 180° for all interior angles.

A = 180 - 39.34 - 25

A = 115.66

$\bf \cfrac{sin(25^o)}{44}=\cfrac{sin(A)}{a}\implies \cfrac{sin(25^o)}{44}=\cfrac{sin(115.66^o)}{a} \\\\\\ a\cdot sin(25^o)=44\cdot sin(115.66^o)\implies a=\cfrac{44\cdot sin(115.66^o)}{sin(25^o)} \\\\\\ a\approx 93.8452\implies \stackrel{\textit{rounded up}}{a = 93.85}$
