Y=f(×)=9×<br> Find f(×) when x =1/2

mojhsa [17]

<h3>f(x) is equal to 4.5 when x = 1/2</h3>

<em><u>Solution:</u></em>

Given that,

$y = f(x) = 9x$

We have to find f(x) when x = 1/2

We can solve by substituting x = 1/2 in given function

$f(x) = 9x\\\\Plug\ in\ x = \frac{1}{2}\\\\f(\frac{1}{2}) = 9 \times \frac{1}{2}\\\\f(\frac{1}{2}) = 4.5$

Thus f(x) is equal to 4.5 when x = 1/2

10 is 32% of what number?

Fantom [35]

Answer:

x= 3,2

Step-by-step explanation:

10 ---------------- 100%

x ---------------- 32%

$x=\frac{10\times32\%}{100\%}$

$x=\frac{10\times32}{100}$

$x=\frac{320}{100}$

$x=\frac{32}{10}$

$x=\frac{32\div2}{10\div2}$

$x=\frac{16}{5}$

$x=3,2$

Find the area of the triangle that has a base of 4.2 mm and a height of 1.5 mm. 2.85 mm2 6.3 mm2 3.15 mm2 5.7 mm2

Advocard [28]

Answer: 3.15 mm²

Step-by-step explanation:

First, we multiply the height by the base: 4.2 x 1.5 = 6.3

But, since this is a triangle, we have to divide this number by 2: 6.3 / 2 = 3.15

Hope this helps you!
