What is the slope of the graph of y = x^2 + 12 -7 at the point x = 4

Mathematics
1 answer:
Doss [256]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Step 1:  find the derivative of y = x^2 + 12x - 7; it is 2x + 12.

This function represents the slope of the tangent line to the given curve at x.

Step 2:  Substitute 4 for x in f '(x) = 2x + 12:  f '(4) = 2(4) + 12 = 20

The slope of the tangent line to the graph of y = x^2 + 12x - 7 at x = 4 is 20.

The distribution of the amount of money spent by first-time gamblers at a major casino in Las Vegas is approximately normal in s
Leya [2.2K]

Answer:

$720

Step-by-step explanation:

Given :

Mean, m = 600

Standard deviation, s = 120

Z = (x - m) / s

P(Z > x) = 84%

P(Z > x) = 0.84

Zscore corresponding to P(Z > x) = 0.84 will be -0.994

Hence,

-0.994 = (x - 600) / 120

120 * -0.994 = x - 600

119.28 = x - 600

119.28 + 600 = x

719.28 = x

Hence,

X = $720

Since the shape is a square, it has 90° angles.

if cut in half, it creates a 45-45-90 triangle.
using this, you can use the ratio of 1:sqrt2 to find x. so the ratio would be x:6 to 1:sqrt2.

divide 6 by sqrt2 to find x, and then rationalize for it to become 6sqrt2/2, which would simplify even further to 3sqrt2

7(x+2)=2x-1 solve for the variable
Len [333]

Answer:

x = - 3

Step-by-step explanation:

Given

7(x + 2) = 2x - 1 ← distribute parenthesis on left side

7x + 14 = 2x - 1 ( subtract 2x from both sides )

5x + 14 = - 1 ( subtract 14 from both sides )

5x = - 15 ( divide both sides by 5 )

x = - 3
