Answer:

Step-by-step explanation:1.1c

The expression for the price last month is 1.1c, and the cell phone was $438.9 last month

The given parameters are:

The price last month would be:

Price = Initial price * (1 + Increment)

This gives

Price = c * (1 + 10%)

Evaluate

Price = 1.1c

We have:

c = 399

So, the expression becomes

Price = 1.1 * 399

Evaluate

Price = 438.9

Hence, the cell phone was $438.9 last month

Answer: 18

Step-by-step explanation:

First we want to turn 20% into a decimal so we can multiply it by 90.

So to do that we divide 20 by 100.

20/100=0.2 so 0.2 is the decimal form of 20%.

Then we multiply 90 by 0.2 to get 18 as our answer.

Answer:

Answer: 20% of 90 is 18.

Let's find 20% of 90.

Explanation

20% of 90 can be written as 20% × 90

= 20/100 × 90

= 18

Thus, 20% of 90 is 18.

Using the normal distribution, it is found that the probability that more than 524 customers will come to the store on a given day is given by:

A. 0.15%.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by:

[tex]\mu = 428, \sigma = 32[/tex].

The probability that more than 524 customers will come to the store on a given day is one subtracted by the p-value of Z when X = 524, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{524 - 428}{32}[/tex]

Z = 3

Z = 3 has a p-value of 0.9985.

Answer:

40

Step-by-step explanation:

The figure shown is a rectangular prism with a length of 1, a width of 8 and a height of 5 and given this information we want to find the volume

The volume of a rectangular prism can easily be calculated by multiplying the width by the length by the height

so the volume of this rectangular prism specifically = 5 * 8 * 1

5 * 8 = 40

40 * 1 = 40

so the volume is 40

Answer:T = 2*Pi / (Pi / 3) = 6 seconds

Step-by-step explanation:

The time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)

Trigonometric functions are periodic. They repeat their values after some specific constant input interval (constant depends on the trigonometric function chosen).

For sine function, its period is 2π

Thus, we get:

[tex]y = \sin(x) = \sin(x+2\pi) = \sin(x + 2\pi n) ; n \in \mathbb Z[/tex] integer, and y is some constant at some constant value of x)

For this case, the pendulum's motion is modeled by:

[tex]P(t) = -10\sin\left(\dfrac{\pi}{3} t\right)[/tex]

Let it takes 'd' seconds to do one full cycle, then we get:

[tex]P(t) = P(t+d) = P(t+2d) = P(t + nd); n \in \mathbb Z - \mathbb Z^{-}[/tex] (n is non-negative integer).

Using the formula, we get:
[tex]-10\sin\left(\dfrac{\pi}{3} t\right) = -10\sin\left(\dfrac{\pi}{3} (t + nd)\right)\\\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t + \dfrac{\pi}{3}nd\right)[/tex]

But we know that:

[tex]\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t +2\pi n\right)[/tex]

Thus, we get:

[tex]2\pi n = \dfrac{\pi}{3}nd\\[/tex] (compared for non-negative values of n)

This gives:

[tex]d = \dfrac{2\pi n \times 3}{\pi n} = 6[/tex] (in seconds)

Thus, the time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)

dy/dx = 4x/y

Sorry if it's wrong!

Answer:

see explanation

Step-by-step explanation:

(1)

y = - x + 4 ( add x to both sides )

x + y = 4

with A = 1, B = 1, C = 4

(2)

y = 5x + 7 ( subtract y from both sides )

0 = 5x - y + 7 ( subtract 7 from both sides )

- 7 = 5x - y , that is

5x - y = - 7

with A = 5, B = - 1, C = - 7

----------------------------------------------------------

(1)

2x + y = 9 ( subtract 2x from both sides )

y = - 2x + 9

with m = - 2, c = 9

(2)

5x + 2y = 7 ( subtract 5x from both sides )

2y = - 5x + 7 ( divide terms by 2 )

y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{7}{2}[/tex]

with m = - [tex]\frac{5}{2}[/tex] , c = [tex]\frac{7}{2}[/tex]

Answer: 3.9 ft

Step-by-step explanation:

From the question, the distance across the window which is 2.5 ft is the diameter. Therefore, radius will be:

= 2.5 / 2

= 1.25 ft

Then, we calculate the circumference of the circle which will be:

= 2πr

= 2 × 3.14 × 1.25

= 7.85 ft

Nite that it's a semi circle, therefore we divide the perimeter by 2. This will be:

= 7.85/2

= 3.9 feet
