What is the slope for the function y=2x^2+2 at the point x= 3?

Answers

Answer 1

Answer: 1) We have to calculate the first derivative:
y=2x²+2
y´=4x

2) the slope at the point x=3; will be f´(3);
f´(3)=4(3)=12

answer: the slope will be 12.

Answer 2

Answer:

Final answer:

The slope of the function y = 2x^2 + 2 at the point x = 3 is 12.

Explanation:

The slope of a function can be determined using the derivative of the function. In this case, the function is y = 2x^2 + 2. Taking the derivative of this function gives us dy/dx = 4x. To find the slope at x = 3, we substitute x = 3 into the derivative: dy/dx = 4(3) = 12.

Step-by-step explanation:

i know this one by doing a long math formula

Answer:

49.0%

Step-by-step explanation:

take the 2 numbers and find the difference

51 - 26 = 25

take the difference and divide it by the orginal number

25÷51 = 0.49019607843

then times that number by 100

(25÷51) × 100 = 49.0196078431

so the number was decreased by 49.0 %

Answers

Answer:

Step-by-step explanation:

Given: From the given figure, it is given that arcDC=112° and arcAB=72°.

To find: the measure of DE.

Solution: From the given figure, it is given that arcDC=112° and arcAB=72°.

Now, it is given that ∠DOC=112° and ∠EOC=180° (straight line)

thus, using the property that the sum of angles around a point is 360°, therefore

∠EOD+∠DOC+∠EOC=360°

⇒∠EOD+112°+180°=360°

⇒∠EOD=68°

Thus, the measure of DE is 68.

Hence, option (C) is correct.

the area of the triangle with sides of lengths 13 cm, 6 cm, and 9 cm is approximately 23.66 square centimeters.

To find the area of a triangle when you know the lengths of all three sides, you can use Heron's formula. Heron's formula states that the area (A) of a triangle with sides of lengths a, b, and c can be calculated using the following formula:

A = √[s(s - a)(s - b)(s - c)]

Where:

s is the semiperimeter (half of the perimeter), given by s = (a + b + c) / 2.

a, b, and c are the lengths of the triangle's sides.

In your case, the lengths of the three sides are a = 13 cm, b = 6 cm, and c = 9 cm. Now, calculate the semiperimeter (s):

s = (a + b + c) / 2

s = (13 + 6 + 9) / 2

s = 14 cm

Now, use Heron's formula to find the area (A):

A = √[14(14 - 13)(14 - 6)(14 - 9)]

A = √[14(1)(8)(5)]

A = √[560]
