wariber [46]

Answer:

30 oranges

Step-by-step explanation:

12 apples : 30 oranges

because 12 apples is 6 times the original ratio, so we multiply the 5 oranges by 6 too.

Show that the equation 2x + 3 cos x + e ^ x = 0 has a root on the interval [- 1, 0]

ExtremeBDS [4]

If x = -1, you have

2(-1) + 3 cos(-1) + e ⁻¹ ≈ -0.0112136 < 0

and if x = 0, you have

2(0) + 3 cos(0) + e ⁰ = 4 > 0

The function f(x) = 2x + 3 cos(x) + eˣ is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < c < 0 such that f(c) = 0.

Which statement describes the function y=ax^n when a=1 and n is odd?

julsineya [31]

ANSWER

B. The graph is symmetric about the origin

EXPLANATION.

The given function is

$y = a {x}^{n}$

When a=1,

$y = {x}^{n}$

Let,

$f(x)= {x}^{n}$

$f(-x)= {( - x)}^{n}$

Since n is odd,

$f(-x)=-{( x)}^{n}$

$\Rightarrow f(-x)=-f(x)$

This implies that, the function

$y={x}^{n}$

is symmetric with respect to origin.

The correct answer is B
