Answer:

64.8°

Step-by-step explanation:

in the given ratio 9:13:3 the required middle angle is presented as 9;

1) if the sum of the angles of triangle is 180, then the given ratio can be re-written as

9x+13x+3x=180, ⇒ x=36/5;

2) if x=36/5, then the required measure of the middle angle can be calculated:

m(∠MIDDLE)=9*36/5=64.8°.

Answer:

0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

Step-by-step explanation:

For each cell, there are only two possible outcomes. Either it will least for at least 10,000 charge-discharge cycles, or it will not. Cells are independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

10 individual cells.

This means that [tex]n = 10[/tex]

95% probability

This means that [tex]p = 0.95[/tex]

What is the probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

This is P(X = 10).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 10) = C_{10,10}.(0.95)^{10}.(0.05)^{0} = 0.5987[/tex]

0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles

Answer:

The rate of the train on level ground is 75 mph, and the rate of the train in the mountains is 30 mph like you mentioned. If you were asking for the time it takes for the train to travel 120 miles in that speed in the mountain, then it would be 4 hours.

Answer:

$65.52

Step-by-step explanation:

y = mx + b

y = amount spent on fuel = ?

m = price per gallon = $3.90

x = gallons  = 16.8

b is not needed for this problem

y = (3.90)(16.8)

y = $65.52

The amount of money that Sam spends on fuel will be $65.52.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

To fill up his fuel tank, Sam puts in 16.8 gallons of gas at $3.90 per gallon.

The amount of money that Sam spends on fuel will be given by the multiplication of the numbers 16.8 and 3.9.

⇒ $3.90 x 16.8

⇒ $65.52

The amount of money that Sam spends on fuel will be $65.52.

Answer:

x=−2 and y=−5

Step-by-step explanation:

Solve3x−2y=4for x:

3x−2y=4

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x /3 = 2y+4 /3 (Divide both sides by 3)

x= 2 /3 y+ 4 /3

Substitute  2 /3 y+ 4 /3 for x in6x−2y=−2:

6x−2y=−2

6( 2 /3 y+ 4 /3 )−2y=−2

2y+8=−2(Simplify both sides of the equation)

2y+8+−8=−2+−8(Add -8 to both sides)

2y=−10

2y /2 = −10 /2 (Divide both sides by 2)

y=−5

Substitute−5 for y in x=

2 /3 y+ 4 /3 :

x= 2 /3 y+ 4 /3

x= 2 /3 (−5)+ 4 /3

x=−2(Simplify both sides of the equation)

Answer:

The coordinates of point L are:

(x₁, y₁) = (-22, 17)

Step-by-step explanation:

We know that the Midpoint Formula is given by:

[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case:

M(-12, 6) is the midpoint. Thus,

(x, y)  = (-12, 6)

N(-2, -5) is the second point, Thus,

(x₂, y₂) = (-2,-5)

We have to determine the coordinates of point L.

Let (x₁, y₁)  be the coordinates of point L.

substituting (x, y)  = (-12, 6), (x₂, y₂) = (-2,-5) in the Midpoint Formula

[tex]\left(-12,\:6\right)=\left(\frac{-2+x_1}{2},\:\:\frac{-5+y_1}{2}\right)[/tex]

Determining the x₁ coordinate of the point L

[tex]\frac{-2+x_1}{2}=-12[/tex]

[tex]-2+x_1=-24[/tex]

Add 2 to both sides

[tex]-2+x_1+2=-24+2[/tex]

Simplify

[tex]x_1=-22[/tex]

Determining the y₁ coordinate of the point L

[tex]\frac{-5+y_1}{2}=6[/tex]

[tex]-5+y_1=12[/tex]

Add 5 to both sides

[tex]-5+y_1+5=12+5[/tex]

Simplify

[tex]y_1=17\:\:\:[/tex]

Therefore, the coordinates of point L are:

(x₁, y₁) = (-22, 17)

It would be very hard to graph this equation correctly as without factoring both the numerator and denominator it would be hard to account for all of the information.

x2−5x+6x2−2x−3x−6(x−2)(x−3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Note that you need to use parentheses around the numerator and around the denominator: f(x) = (2x^2+4)/(x^2+5x+6)

Division by zero is undefined, so x≠-2 and x≠-3.

Vertical asymptotes: x=-2, and x=-3

As x approaches ∞, f(x) approaches 2.

As x approaches -∞, f(x) approaches 2.

Horizontal asymptote: y=2
