Answer:

E, 3.

Step-by-step explanation:

Since both f(x) and g[f(x)] are quadratic polynomials, g(x) must also be a linear polynomial.

Let g(x) = Ax + B, where A and B are constants to be determined.

Then we have A[2x² - 3x + 1] + B ≡ x² - (3/2)x + 3.

=> A = 1/2 and B = 5/2.

Hence, f[g(-1)] = f[(1/2)(-1) + (5/2)] = f(2) = 2(2)² - 3(2) + 1 = 3. (E)

CWhich dimensions can create more than one triangle?
three angles measuring 75°, 45°, and 60°
three sides measuring 7 m, 10 m, and lym
three angles measuring 40°, 50%, and 60°
three sides measuring 3 cm, 4 cm, and 5 cm

Answers

Answer:

Step-by-step explanation:

three angles measuring 75°, 45°, and 60°

75+45+60 = 180 -> can create triangle

three sides measuring 7 m, 10 m, and lym (assume this is 16)

satisfy this a-b<c<a+b -> can create triangle

three angles measuring 40°, 50%, and 60°

40+50+60 = 150 ≠ 180 -> cannot create triangle

three sides measuring 3 cm, 4 cm, and 5 cm

satisfy this a-b<c<a+b -> can create triangle

Given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line.

Answers

Here, 2x - 3y - 5 = 0

3y = 2x - 5

Divide the equation by 3,
y = 2/3x - 5/3

Compare it with,y = mx + c
So, slope (m) = 2/3

In short,Your Answer would be: 2/3
