The sum of 11 and k??

Answers

Answer 1

Answer: 11 + k

The 'sum' means addition. If the problem gives you a k value, therefore you can just plug the k value in for K.

4/n+9 = 2/7

What is the answer please!

Answers

Answer:

Step-by-step explanation:

Assuming the n+9 is in the denominator, start by cross multiplying.

multiply the n+9 by 2 and 4 by 7 to form the eqution 2n+18 = 28.

subtract the 18 from both sides to form the equation 2n = 10.

divide both sides by 2 to answer n = 5.

Another method is to think how to create equivalent fractions. to have 4/n+9 equal 2/7, the 2/7 is equivalent to 4/14. that means that n+9 is equivalent to 14, because the numerator are equal to each other. if n+9 = 14, then n = 5.

The coordinates of the point on the curve y=x²+3x+4 the tangent at which passes through the origin are - a. (-2,2)(2,14) b. (1, -1) (3,4) c. (2.14)(2,2) d. (1,2) (14,3)

Answers

To find the coordinates of the point on the curve where the tangent passes through the origin, we need to find the equation of the tangent line and then solve for the x-coordinate of the point of tangency.

Let's break it down step by step:

1. Start with the equation of the curve: y = x² + 3x + 4.

2. Find the derivative of the curve to find the slope of the tangent line. The derivative of y = x² + 3x + 4 is dy/dx = 2x + 3.

3. Set the derivative equal to the slope of the line passing through the origin, which is 0 since the line is horizontal. So, 2x + 3 = 0.

4. Solve the equation to find the x-coordinate of the point of tangency. Subtract 3 from both sides: 2x = -3. Divide by 2: x = -3/2.

5. Plug the x-coordinate back into the original equation to find the y-coordinate. y = (-3/2)² + 3(-3/2) + 4 = 9/4 - 9/2 + 4 = 9/4 - 18/4 + 16/4 = 7/4.

6. Therefore, the point on the curve where the tangent passes through the origin is (-3/2, 7/4).

None of the given options match the coordinates (-3/2, 7/4). Therefore, none of the options are correct.

Multiply (3)(-4)(2).

Are these ratios equivalent?18 children : 12 adults
16 children : 20 adults
yes
no

Answers

Answer:

Step-by-step explanation:

If product of mean = product of extreme, then ratios are equivalent.

18 : 12 :: 16:20

Product of mean = 12 * 16 = 192

Product of extreme = 18 * 20 = 360

Not equivalent ratios
