Given the function f(x)=3x-5, for which value in the domain does f(x)=-38?

victus00 [196]

$f(x) = -38\\\\\implies 3x -5 = -38\\\\\implies 3x = -38 +5 \\\\\implies 3x = -33\\\\\implies x = -\dfrac{33}{3}\\\\\implies x = -11$

Explain in words what mistake you made and how will correct it. in a group of 20 children,there were 8 girls. which is the ratio

Nataly_w [17]

Well first do 20 children minus 8 girls to find how many boys there are:
20-8=16
So there are 16 boys. Therefore we can write the ratio of girls to boys as:
8/16
Then we can simplify this ratio by dividing it by 8 to get:
1/2
So the answer is the ratio of girls to boys in the group in simplest form is 1/2.

Answer:

19,463 cm²

Step-by-step explanation:

The area is given by the formula ...

A = (1/2)ij·sin(K)

Filling in the values, we find the area to be ...

A = (1/2)(270 cm)(170 cm)·sin(122°) ≈ 19,463 cm²
