-8j + 14 = -2(4j-7)
So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.

Karl starts the engine on his small private airplane. The engine drives a propeller with a radius of 9 feet and its centerline 12.5 feet
above the ground. At idle, the propeller rotates at a constant speed of approximately 750 revolutions per minute. The height of one
propeller tip as a function of time is given by h = 12.5 + 9 sin(7501), where h is the height in feet and t is the time in minutes. Find h
when t= 3.5 minutes.
Answers
Answer: The height of one propeller tip is 3.68 feet when t= 3.5 minutes.
Step-by-step explanation:
Given: The height of one propeller tip as a function of time is given by [tex]h = 12.5 + 9 sin(750t)[/tex]), where h is the height in feet and t is the time in minutes.
Put t = 3.5 , we get
[tex]h=12.5 +9 \sin (750\times3.5)\\\\=12.5+9\sin (2625)\\\\=12.5+9(-0.9802)\\\\=12.5-8.8218=3.6782\approx3.68[/tex]
Hence, The height of one propeller tip is 3.68 feet when t= 3.5 minutes.

(6x - 1) + (5x + 19)=128
Answers
Answer:
10
Step-by-step explanation:
add like terms
6x+5x=11x
19-1=18
11x+18=128
subtract 18 from both sides
11x=110
110/11=10
x=10
(6x-1) + (5x+19) = 128
Collect like terms
11x + 18 = 128
Move the constant to the right
11x=128-18
11x=110
Divide both sides
X=10

(This is a question from arithmetic sequence) Jay’s dog weighs 35 kilograms and is overweight. The dog is put on a diet, losing 0.4kg
every week. How long does it take to reach the target weight of 28 kilograms?
Answers
Answer:
17.6 weeks
Step-by-step explanation:
The computation of the time taken to reach the target weight is shown below:
35, 34.6, 34.2...............28
As we know that
a_n = a + (n - 1)d
28 = 35 + (n - 1)(-0.4)
28 = 35 -0.4n + 0.4
28 = 35.04 - 0.4n
0.4n = 35.04 - 28
0.4n = 7.04
n = 17.6

14) Marketten (100 + x) mL vişne suyu ve (200 + 2x) mL şeftali suyu alan Burak,
toplam 375 mL meyve suyu almış oldu. Buna göre Burak, meyve sularından kaçar mL almıştır?
Answers
Burak'ın aldığı vişne suyu miktarı = (100 + x) ml
Burak'ın aldığı şeftali suyu miktarı = (200 + 2x) ml
Burak'ın aldığı toplam meyve suyu miktarı = 375 ml
Bu ifadeler aşağıdaki gibi bir denklem olarak yazılabilir :
[tex] =\tt 100 + x + 200 + 2x = 375[/tex]
[tex] = \tt100 + 200 + x + 2x = 375[/tex]
[tex] =\tt 300 + 3x = 375[/tex]
[tex] = \tt3x = 375 - 300[/tex]
[tex] =\tt 3x = 75[/tex]
[tex] =\tt x = \frac{75}{3} [/tex]
[tex]\hookrightarrow\color{plum}\tt x = 25[/tex]
Böylece x = 25'in değeri
Burak'ın aldığı vişne suyu miktarı :
[tex] =\tt 100 + 25[/tex]
[tex]\color{plum} = \tt125 \: ml[/tex]
Böylece Burak'ın aldığı Berry suyu miktarı = 125 ml
Burak'ın aldığı şeftali suyu miktarı :
[tex] =\tt 200 + 2 \times 25[/tex]
[tex] =\tt 200 + 50[/tex]
[tex]\color{plum} = \tt250 \: ml[/tex]
Böylece Burak'ın aldığı şeftali suyu miktarı = 250 ml
○=> Bu nedenle :
▪︎Burak'ın aldığı meyve suyu miktarı = 125 ml
▪︎Burak'ın aldığı şeftali suyu miktarı = 250 ml

What is the perimeter of a square if the length of one of the diagonals is 12 cm?
6v2 cm
2412 cm
48 cm
24 cm
Answers
Answer:
Step-by-step explanation:
Use Pythagorean theorem to find the length of the square.
Length of the square = a
a² +a² = diagonal²
2a² = 12²
2a² = 144
a² = 144 ÷ 2
a² = 72
[tex]a =\sqrt{72}\\\\ = \sqrt{2*2*2*3*3}\\\\ = 2*3\sqrt{2}\\\\a = 6\sqrt{2}\\\\\\\\Perimeter= 4a\\\\ = 4*6\sqrt{2}\\\\= 24\sqrt{2} cm[/tex]
