Given f(x)=2x2-3, find F(-3)

Paraphin [41]

Answer:

f(-3) = 15

Step-by-step explanation:

f(x)= 2x^2 - 3

Plug in x = -3 into the function

f(-3) = 2(-3)^2 - 3

f(-3) = 18 - 3

f(-3) = 15

3+-√(-3)^2 - 4(5)(-1)

Alona [7]

Answer:

Step-by-step explanation:

Easy way to do this is step by step. Your quadratic, from your entry, must be

$5x^2-3x-1$ .

Step by step looks like this, one thing at a time:

$x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)}$ becomes

$x=\frac{3+\sqrt{9-(-20)} }{10}$ becomes

$x=\frac{3+\sqrt{9+20} }{10}$

and this of course is

$x=\frac{3+\sqrt{29} }{10}$

Do the same with the subtraction sign to get the other solution.

If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign. If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Just my advice as a high school math teacher.

Pamela is 7 years younger than Jiri. The sum of their ages is 39. What is Jiri ‘s age?

astraxan [27]

Based on the task given, Pamela's age and juri's age is 16 and 23 years respectively.

<h3>Equation</h3>

Juri's age = x
Pamela's age = x - 7
Their total age = 39

x + (x - 7) = 39

x + x - 7 = 39

2x = 39 + 7

2x = 46

x = 46/2

x = 23

Therefore,

Juri's age = x

= 23 years

Pamela's age = x - 7

23 - 7

= 16 years

\frac{3}{4} \times 2 =

suter [353]

To multiply two fractions, you simply multiply numerators and denominators together.

2 can be read as the fraction 2/1

So, the multiplication is

$\dfrac{3}{4} \times \dfrac{2}{1} = \dfrac{3\times 2}{4 \times 1} = \dfrac{6}{4} = \dfrac{3}{2}$
