At birth, one puppy weighs 15/16 pounds. A second puppy weighs 1 and 1/8 pounds. How much more did the second puppy weigh?

zvonat [6]

Answer:

3/16 pounds more.

Step-by-step explanation:

It is 1 1/8 - 15/16

= 9/8 - 15/16

= 18/16 - 15/16

= 3/16.

Which of the following is a solution of 4x2 = − 9x − 4?

mestny [16]

The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it

Finding Derivatives Implicity In Exercise, find dy/dx implicity.<br> 4x3 + ln y2 + 2y = 2x

lisov135 [29]

Answer:

$\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}$

Step-by-step explanation:

Given function : 4x³ + ln(y²) + 2y = 2x

on differentiating both sides with respect to 'x', we get

$\frac{d(4x^3 + ln(y^2) + 2y)}{dx}= \frac{d(2x)}{dx}$

$12x^2+\frac{2}{y}(\frac{dy}{dx})+2(\frac{dy}{dx})=2$

$12x^2+(\frac{2}{y}+2)\frac{dy}{dx}=2$

$(\frac{2+2y}{y})\frac{dy}{dx}=2-12x^2$

$\frac{dy}{dx}=\frac{y(2-12x^2)}{2+2y}$

$\frac{dy}{dx}=\frac{2y(1-6x^2)}{2(1+y)}$

$\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}$

Solve each system of equations by graphing Y=3x+4 and y=-x-4

In-s [12.5K]

Y = 3x + 4
y = -x - 4

3x + 4 = -x - 4
3x + x = -4 - 4
4x = -8
x = -8/4
x = -2

y = 3x + 4
y = 3(-2) + 4
y = -6 + 4
y = -2

solution is (-2,-2) <==

Find the approximate value of the circumference of a circle with the given radius. UseT 3.14. Round your results to one more dec

Temka [501]

Answer:

25.1 inches

Step-by-step explanation:

Radius of the circle = 4 inches

We have to calculate the value of Circumference of the circle.

The formula to calculate the circumference is:

Circumference = 2πr

We have to use π = 3.14, as said in the question:

So using the values, we get:

Circumference = 2 x 3.14 x 4 = 25.12 inches

Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.

Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches
