Given The following Graph:<br><br> a.)Evaluate f(0). <br> b.) Solve for f(x) = -3

dlinn [17]

Answer:

see explanation

Step-by-step explanation:

f(0) means find the value of y when x = 0

That is f(0) = 1 ← the point (0, 1) on the graph

When f(x) = - 3 means what are the values of x corresponding to y = - 3

From the graph when y = - 3 there are 2 corresponding values of x, that is

x = - 2 or x = + 2

The solution to f(x) = - 3 is x = ± 2

marishachu [46]

Answer:

There are 178 more boys in Barlow school as compared to Willow school.

Step-by-step explanation:

We are given the following in the question:

Barlow school:

Total number of students = 873

Number of boys =

$=\dfrac{4}{9}\times 873 = 388$

Willow school:

Total number of students = 630

Number of girls =

$=\dfrac{2}{3}\times 630 = 420$

Number of boys =

Total number of students - total number of girls

$=630-420 = 210$

Thus, Barlow school has greater number of boys than Willow school.

Difference between the number of boys =

$=388-210\\=178$

Thus, there are 178 more boys in Barlow school as compared to Willow school.

Divide 25kg in the ratio 2:3:5

fgiga [73]

First, add up the parts of the ratio...
2+3+5=10
then divide the whole into individual parts...
25/10=2.5
then multiply the value of 1 part by the amount in the ratio...
2.5 x 2 =5
2.5 x 3 = 7.5
2.5 x 5 = 12.5
so the final ratio is 5kg:7.5kg:12.5kg
Hope this helps :)
