\large \bold {ANSWER}

\large \boxed { \large \sf \green{ A. y= -4x+2 }}

\large \bold {SOLUTION}

Convert y - 6 = -4(x + 1) to slope intercept form.

First thing that we need to do is to distribute -4 to all terms within the parenthesis properly.

  • y - 6 = -4(x + 1) = -4x - 4
  • y - 6 = -4x - 4

Hence, we will add 6 both sides:

  • y - 6 + 6 = -4x - 4 + 6
  • y = -4x + 2

Therefore, the equation describes the same line as y - 6 = -4(x + 1) is <u>y</u><u> </u><u>=</u><u> </u><u>-4x + 2</u>. (letter A.)

A. Y= -4x + 2

We first distribute the -4 in the parenthesis.
-4(x+1) —> -4x - 4

Then we add 6 to both sides to get rid of it on the left. The right side then becomes:
-4x + 2

This is because -4 + 6 is 2

So, we are left with:
y = -4x +2

The velocity of an object is given by the following function defined on a specified interval. Approximate the displacement of th
harkovskaia [24]

Answer:

The displacement of the object on this intervals is 1.33 m.

Step-by-step explanation:

Given that,

The function of velocity is

v=\dfrac{1}{2t+4}\ m/s

For 0 ≤ t ≤8 , n = 2

We need to calculate the intervals

Using formula for intervals

For, n = 1

\Delta x=\dfrac{t_{f}-t_{i}}{n}

\Delta x=\dfrac{8-0}{2}

\Delta x=4

So, The intervals are (0,4), (4,8)

We need to calculate the velocity

Using given function

v=\dfrac{1}{2t+4}

For first interval (0,4),

Put the value into the formula

v_{0}=\dfrac{1}{2\times0+4}

v_{0}=\dfrac{1}{4}

For first interval (4,8),

Put the value into the formula

v_{4}=\dfrac{1}{2\times4+4}

v_{4}=\dfrac{1}{12}

We need to calculate the total displacement

Using formula of displacement

D=(v_{0}+v_{4})\times(\Delta x)

Put the value into the formula

D=(\dfrac{1}{4}+\dfrac{1}{12})\times4

D=1.33\ m

Hence, The displacement of the object on this intervals is 1.33 m.

Please differentiate this problem
strojnjashka [21]

Answer:

dy/dx = d/dx sin(x-3/x+2)

dy/dx = cos(x-3/x+2) . d/dx (x-3/x+2)

dy/dx = cos(x-3/x+2) . (x + 2 - x + 3)/(x+2)²

dy/dx = [5cos(x-3/x+2)]/(x + 2)²

Suppose the life of a particular brand of laptop battery is normally distributed with a mean of 8 hours and a standard deviation
Ierofanga [76]

Answer:

4.75% probability that the battery will last more than 9 hours before running out of power

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 8, \sigma = 0.6

What is the probability that the battery will last more than 9 hours before running out of power g

This is 1 subtracted by the pvalue of Z when X = 9. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{9 - 8}{0.6}

Z = 1.67

Z = 1.67 has a pvalue of 0.9525

1 - 0.9525 = 0.0475

4.75% probability that the battery will last more than 9 hours before running out of power
