Find y when x=21/2, if y varies inversely as x and x=5 when y=3A. 2.5/3=3/4;6
B. 2.5/3=3/4;3
C. 2.5/3=5/3;6
D. 2.5/3=5/4;3

Answers

y varies inversely as x:
y=C/x
C: Constant

Cross multiplication
yx=C

x=5 when y=3
Replacing in the equation above:
(3)(5)=C

when x=2 1/2=2+0.5→x=2.5, y=?
xy=C
(2.5)(y)=C

Equaling the two equations:
C=C
(2.5)(y)=(3)(5)
2.5/3=5/y

Solving for y. Dividing both sides of the equation by 2.5:
(2.5)(y)/(2.5)=(3)(5)/(2.5)
y=6

Answer:
2.5/3=5/6

The sum of three number is 126. The third number is 4 times the second. The second number is 6 less than the first. What are the numbers?

Answers

The numbers are 26, 20, and 80.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Threenumbers:

First = a

Second = b

Third = c

Now,

a + b + c = 126 ____(1)

c = 4b ____(2)

b = a - 6 _____(3)

From (1), (2), and (3) we get,

a + (a - 6) + 4b = 126

a + a - 6 + 4b = 126

2a + 4b = 126 + 6

2a + 4b = 132

2a + 4(a - 6) = 132

2a + 4a - 24 = 132

6a = 132 + 24

6a = 156

a = 26

Now,

a = 26

b = a - 6 = 20

c = 4b = 4 x 20 = 80

Thus,

The numbers are 26, 20, and 80.

Lets define a=1st number, b=2nd number, and c=3rd number

We know that a+b+c=126

We also know that the second number is 6 more than the first, so we can represent this as b=a+6

We also know that the third number is 3 times the first which can be represented as c=3a

We can plug these new values into our original equation and get:

a+(a+6)+(3a)=126

2a+6+3a=126 COMBINE LIKE TERMS

5a+6=126

5a=120

a=24

Our first number is 24.

Our second number is 6 more than our first number, so the second number is 24+6=30

Our third number is 3 times the first number, so the third number is 3(24)=72

We can check by plugging these numbers in for a, b, and c in our original equation

a+b+c=126

24+30=72=126

126=126

Find the product of (3.7 × 104) and 2

Answers

"769.6" I hope it helps

im assuming the "and 2" part means to also multiply so just multiply 3.7*104 to get 384.8. then multiply the product by 2 and the answer will be 769.6.

The curve produced by the water coming from a hose is sketched onto a graph with zeros at 0 and 5. The point (4, 1) also lies on the curve. If h(x) represents the vertical distance from where the water first comes out of the hose and x represents the horizontal distance, which statements are true? Check all that apply.A.The scenario can be represented by the function h(x) = –0.25(x)(x – 5).
B.The scenario can be represented by the function h(x) = (x)(x + 5).
C.The vertex is on the line x = 2.5.
D.The greatest height that the water reaches is 1.5 units.
E.The scenario can be represented by the function h(x) = –1(x – 5).

Answers

The statements that are true are:

A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).

E. The scenario can be represented by the function h(x) = –1(x – 5).

which statements are true?

Given that the curve produced by the water from the hose has zeros at 0 and 5 and passes through the point (4, 1), determine which statements are true.

A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).

To check if this statement is true, substitute the given point (4, 1) into the equation:

h(4) = –0.25(4)(4 – 5) = –0.25(4)(-1) = 0.25(4)(1) = 1

Since h(4) evaluates to 1, which matches the y-coordinate of the given point, this statement is true.

B. The scenario can be represented by the function h(x) = (x)(x + 5).

This statement does not match the given information since the function does not account for the zeros at 0 and 5. Therefore, this statement is false.

C. The vertex is on the line x = 2.5.

Since the vertex is not mentioned or indicated by the given information, we cannot determine its exact location. Therefore, this statement is undetermined.

D. The greatest height that the water reaches is 1.5 units.

Since the given point (4, 1) lies on the curve, and no other information suggests a greater height, we cannot conclude that the greatest height reached is 1.5 units. Therefore, this statement is false.

E. The scenario can be represented by the function h(x) = –1(x – 5).

To check if this statement is true, let's substitute the given point (4, 1) into the equation:

h(4) = –1(4 – 5) = –1(-1) = 1

Since h(4) evaluates to 1, which matches the y-coordinate of the given point, this statement is true.

In summary, the statements that are true are:

A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).

E. The scenario can be represented by the function h(x) = –1(x – 5).
