Answer:

I'm not sure what that U is for.

The answer is 459,461 These two do add to 920

Step-by-step explanation:

Remark

I'm going to make sure you are using consecutive odd numbers.

Let the smaller number = 2x - 1

Let the larger number = 2x + 1

Equation

2x - 1 + 2x + 1 = 920

4x = 920

x = 230

The consecutive numbers are 2*230 - 1 = 459

and 2*230 + 1 = 461

A. The slope of the curve y=x^3- 1 at the point P(1,0) is<br> .

Ierofanga [76]

Answer:

3

Step-by-step explanation:

The measure of the slope is $\frac{dy}{dx}$ at x = a

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x³ - 1, then

$\frac{dy}{dx}$ = 3x²

The slope at (1, 0) is

$\frac{dy}{dx}$ = 3(1)² = 3

NEED HELP!!!!!!!!!!!

Answer: last option/D

Step-by-step explanation:

It says to do h(t) divided by g(t) so

1- you see that h(t) is 4t +2

2- you see that g(t) is 2t-1

3- you put h(t) on top of g(t)

So, it is 4t+2/2t-1
