What is the amplitude of the function graphed below?

The graph is a quadratic function, and the equation of the function is C(x) = (x + 4)(x - 3)

From the graph the x-intercepts are:

x = -4 and x = 3

Rewrite as:

x + 4 = 0 and x - 3 = 0

Evaluate the product of both equations

(x + 4) * (x - 3) = 0* 0

This gives

(x + 4)(x - 3) = 0

Express as a function

C(x) = (x + 4)(x - 3)

Hence, the equation of the function is C(x) = (x + 4)(x - 3)

The angle 11π/12 radian after converting it to degree it become 165 degree.

The measurement between the two lines is called an "Angle" when the two lines or rays converge at a common location.

We have given:

An angle 11π/12

Let's denote it with β

[tex]\rm \beta = \dfrac{11\pi}{12}[/tex]

To convert it to degree, replace π with 180°, we get:

[tex]\rm \beta = \dfrac{11\times180}{12}[/tex]

β = 165°

Thus, the angle 11π/12 radian after converting it to degree it become 165 degree.

Answer:

Diverge

Step-by-step explanation:

Each successive term is larger than the previous one, so the series will diverge.

The given series can be condensed to

[tex]\displaystyle \frac14 + \frac13 + \frac49 + \frac{16}{27} + \frac{64}{81} + \cdots = \frac14 \left(1 + \frac43 + \frac{4^2}{3^2} + \frac{4^3}{3^3} + \cdots\right) = \frac14 \sum_{n=0}^\infty \left(\frac43\right)^n[/tex]

which is a geometric series with ratio 4/3. Since this ratio is larger than 1, the sequence of partial sums of the series diverges, so the infinite series also diverges.

We can also just the n-th term test:

[tex]\displaystyle \lim_{n\to\infty} \frac14 \left(\frac43\right)^n = \frac14 \lim_{n\to\infty} \frac{4^n}{3^n} = \infty[/tex]

since 4ⁿ > 3ⁿ for all n > 0.

Answer: 9

Step-by-step explanation:

½bh = 29.25

½ × 6.5 × b = 29.25

B= 29.25/ 3.25

The length of the base of the triangle is 9 centimeters.

The area of a triangle is simply expressed as half base multiplied by height.

Area A = 1/2 × base length × height

Given the dimensions of the triangle:

Area A = 29.25 square centimeters

Height = 6.5 centimeters

Base length =?

To find the height of the triangle, plug the given values into the above formula and solve for h:

Area A = 1/2 × base length × height

29.25  = 1/2 × base length × 6.5

29.25  = base length × 3.25

Base length = 29.25 / 3.25

Base length = 9 cm.

Therefore, the base length measures 9 centimeters.

The volume of the coffee in each tank will be 1760. in³. The mass of cold coffee and hot coffee will be 6163.29 oz and 10213.45 oz. Then the number of the tank placed on a table is one only.

She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.

The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.

Then the volume of the coffee in each tank will be

We know that the dimension of both tanks is equal. Then the volume will remains equal.

Volume = L × B × H

Volume = 8.75 × 8.75 × 23

Volume = 1760.9375 ≅ 1760.94 in³

Then  the mass of the coffee in each the tank will be

The mass of hot coffee will be

Mass = Density × Volume

Mass = 5.8 × 1760.94

The true statements are:

From the complete question, we have the dimensions of the parking lot to be: 78 meters by 19 meters

Also, the dimension of the aisle is: 8 meters by 78 meters

The total parking area is the difference between the parking lot area and the aisle area

This gives

Parking Area = 78 * 19 - 8 * 78

Parking Area = 858

The total area available for cars to park is 858 square meters

The number of parking lot is the quotient of the total parking area and the area of each compact

So, we have:

n = 858/12.5

n = 68.64

Remove the decimal

n = 68

Hence, the number of parking space is 68

The number of parking lot is the quotient of the total parking area and the area of each non-compact space

So, we have:

n = 858/(5.5 * 3)

n = 52

Hence, the number of parking space is 52

To calculate a patient's heart rate, the doctor must take into account a segment of time, such as a minute, and count the number of times the heart beats in that segment.

Heart rate is a term that refers to the number of heart contractions or beats per unit of time.

Heart rate is usually measured at various points, but most commonly it is measured at the wrist, neck, or chest.

According to the above, the most common way for the doctor to establish the patient's heart rate is to count the heart beats in a segment of time such as one minute.

15x=-42-19y

3x=-54-19y

Subtract both

Put in second

So

Answer:

1, -3

Step-by-step explanation:

Solve the system of linear equations:

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

Subtract the equations to eliminate y:

     15x = -42 - 19y

-      3x = -54 - 19y

    ----------------------

    12x = 12

⇒ x = 12 ÷ 12

⇒ x = 1

Now substitute the found value of x into one of the equations and solve for y:

⇒ 15x = -42 - 19y

⇒ 15(1) = -42 - 19y

⇒ 15 = -42 - 19y

⇒ 19y = -42 - 15

⇒ 19y = -57

⇒ y = -57 ÷ 19

⇒ y = -3

Therefore, x = 1 and y = -3
