If f(x) = 0, means " For which value of x, f(x) or y = 0".
Then f(x) = 0 for all points of the graph that intersects the x-axis, that is:

for x = -2, for x = 1 and for x = 3 (Answer -2, 1 or 3 only)

10 exponent negative 9 divided by 10 exponent negative 3

anygoal [31]

$\frac{x^a}{x^b}=x^{a-b} \\ x^{-a}= \frac{1}{x^a} \\ \\ \\ \frac{10^{-9}}{10^{-3}} =10^{-9-(-3)}=10^{-9+3}=10^{-6}= \frac{1}{10^6} = \frac{1}{1000000} =0,000001$

Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4

sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

$y\propto (x+2)^2$

When x=8 and y=250

We have to find the value of y when x=4

$y=k(x+2)^2$

Where k= Proportionality constant

Substitute the values

$250=k(8+2)^2$

$250=100k$

$k=\frac{250}{100}$

$k=5/2$

Now, substitute x=4 and k=5/2

Then, we get

$y=\frac{5}{2}(4+2)^2$

$y=\frac{5}{2}\times 36$

$y=90$

During a nature walk Jill identified 20 species of animals and plants she said that 1/3 of the species she identified were anima

riadik2000 [5.3K]

No because if you split 20 by 3 it’ll give you a decimal and you can’t find half of a plant or half of an animal
