Y is directly proportional to the square of x.

Mathematics
1 answer:
RUDIKE [14]3 years ago

Answer:

The value of y is 847 for x=11

Step-by-step explanation:

It is given that y is directly proportional to the square of x

This can be written mathematically as:

y \propto  x^2

Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k

y = kx^2

Given that "When x is 5, y is 175"

175 = k (5)^2\\175 = k*25\\k = \frac{175}{25}\\k = 7

Putting the value of k

y = 7x^2

Now putting x = 11

y = 7(11)^2\\y = 7 * 121\\y = 847

Hence,

The value of y is 847 for x=11

What are the coefficients of 8+5x-y
lidiya [134]

Answer:The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.

So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.

Why? because it stands in front of the variable.

The equation I wrote was F=9/5C+32 Rearrange the equation and solve for C
Trava [24]
F=9/5C+32
rewrite as 9/5C+32=F
9/5C+32-32=F-32
9/5C=F-32
(5*9/5)C=(F-32)*5
9C=5F-160
9/9C=(5F-160)/9
C=(5F-160)/9

Please help with picture below.
Bess [88]

Answer:

10.5 cm

Step-by-step explanation:

Since we know that O lies on AB we know that:

  1. The distance from the midpoint of OA to O is 6 cm (12/2).
  2. The distance from the midpoint of OB to O is 4.5 cm (9/2).

You can add 6 to 4.5 to get 10.5 cm.
