PLEASE HELP I GIVE LOTS OF POINTS Determine The Range Of The Function Graphed Above.A. [-4, 0]B. (0,4)C.

Answers

Answer 1

9514 1404 393

Answer:

  D. (-∞, 4]

Step-by-step explanation:

The range is the vertical extent of the graph. The graph extends off the bottom, so the lower end of the range is -∞. The peak values are y=4, so the upper end of the range is 4.

Expressed in interval notation, the range is ...

  (-∞, 4]

_____

Additional comment

The right-side bracket is square because the value 4 is included in the range. The left side bracket is rounded because there's no specific number equal to -∞. We can only say the lowest value of y is greater than -∞.

Answer 2

Answer: (-∞, 4]

Step-by-step explanation: Top of function stops at 4, and is negatively continuous.

Dan and Brian have played 51 tennis matches.
Dan has won 29 times.
Brian won the rest.
a) Estimate the probability that Dan wins.
b) Estimate the probability that Brian wins.

Answers

Answer:

A = 29/51   B = 22/51

Step-by-step explanation:

(E) =  number of favorable outcomes/ total number of possible outcomes

- number of possible outcomes= 51

- number of favorable outcomes= 29

therefore, P(E) = 29/51

- number of possible outcomes= 51

- number of favourable outcomes = 51 - 29 = 22

therefore, P(E)= 22/51

Step-by-step explanation:

Use the compound interest formula and substitute the values given:

$250,000=P(1+0.0412)12(15)

Simplify using order of operations:

$250,000=P(301/300)180

Find the perimeter of the triangle whose vertices are (−4,4), (−4,1), and (−8,−4). Write the exact answer. Do not round.

Answers

Answer:

Step-by-step explanation:

The perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

How to determine the perimeter?

The coordinates are given as:

(−4,4), (−4,1), and (−8,−4).

Calculate the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(-4 + 4)^2 + (4-1)^2} = 3[/tex]

[tex]BC = \sqrt{(-4 + 8)^2 + (1+4)^2} = \sqrt{41[/tex]

[tex]AC = \sqrt{(-4 + 8)^2 + (4+4)^2} = \sqrt{80[/tex]

The perimeter is the sum of the side lengths.

So, we have:

[tex]P = 3 + \sqrt{41} + \sqrt{80}[/tex]

Expand

[tex]P = 3 + \sqrt{41} + 4\sqrt{5}[/tex]

Hence, the perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

12 + 4[5% - 4(x + 5)] = 7 - 5x

Answers

Answer:

https://brainly.com/question/24983242 help

Step-by-step explanation:

12 + 4[5% - 4(x + 5)] = 7 - 5x

12 + 4•(5% - 4•(x + 5)) = 7 - 5•x

11x = -55

x = -5

Answer:

[tex]x = - \frac{34}{5} [/tex]

Step-by-step explanation:

12 + 4 (5% - 4(x + 5)) = 7 - 5x

12 + 4 (5/100 - 4x - 20) = 7 - 5x

12 + 4 (-399/20 - 4x) = 7 - 5x

12 - 399/5 - 16x = 7 - 5x

-399/5 - 16x = 7 - 5x

-16x + 5x = 7 + 339/5

-11x = 374/5

Step-by-step explanation:

Víctor has 2 times as many trophies as Dean. Together ,víctor and Dean have 27 trophies does víctor have?

Answers

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

Length of the hypotenuse of the right angled triangle (h) = 2.5 cm

Length of one of the side (a) = 1.5 cm

Let the length third side be 'b' cm

By Pythagoras theorem

h² = a² + b²

Adding Values on both sides

⇒ (2.5)² = (1.5)² + b²

⇒ 6.25 = 2.25 + b²

⇒ 6.25 - 2.25 = b²

⇒ 4 = b²

⇒ √4 = b

⇒ 2 = b

⇒ b = 2
