Which fraction is bigger 7/36, or 4/9

Answers

Answer:

4/9 is bigger

Step-by-step explanation:

For the 1st fraction, since 9 × 4 = 36,

4/9 = 4 × 4

        9 × 4 = 16/36

Likewise, for the 2nd fraction, since 36 × 1 = 36,

7/36= 7 × 1

        36 × 1 = 7/36

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

16/36> 7/36 or 4/9 > 7/36
7/36 is bigger

Which equation represents the vertex form of the equation y=x^2-20x+104?

Answers

From the graph above, the vertex of the graph (h,k) is (10,4).

The general equation in its vertex form is,

y=(x-h)^2+k

Therefore,

y=(x-10)^2+4

Hence, option D is the correct answer.

A circle has a diameter of 12 units, and its center lies on the x-axis. What could be the equation of the circle? Check all that apply.(x – 12)2 + y2 = 12
(x – 6)² + y² = 36
x² + y² = 12
x² + y² = 144
(x + 6)² + y² = 36
(x + 12)² + y² = 144

Answers

Answer:

Options 2 and 5.

Step-by-step explanation:

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2      ... (1)

where, (h,k) is center and r is radius.

We need to find the circle that has a diameter of 12 units, and its center lies on the x-axis.

radius=(Diameter)/(2)=(12)/(2)=6

So, radius of required circle must be 6 and center is in the form of (a,0).

The first equation is

(x-12)^2+(y)^2=12       .... (2)

On comparing (1) and (2) we get  

h=12,k=0,r=√(12)

Center of the circle is (12,0) and radius is √(12). So, option 1 is incorrect.

Similarly,

For equation 2, center of the circle is (6,0) and radius is 6. So, option 2 is correct.

For equation 3, center of the circle is (0,0) and radius is √(12). So, option 3 is incorrect.

For equation 4, center of the circle is (0,0) and radius is 12. So, option 4 is incorrect.

For equation 5, center of the circle is (-6,0) and radius is 6. So, option 5 is correct.

For equation 6, center of the circle is (-12,0) and radius is 12. So, option 6 is incorrect.

Therefore, the correct options are 2 and 5.
its the 2nd and the 5th

Help please!!!!! asap

Answers

Answer:

w \leq \: 26

Step-by-step explanation:

(9w - 4)/(5) \leq (7w + 2)/(4)

First of all cross multiply

That's

4(9w - 4) \leq5(7w + 2)

Expand the terms

36w - 16 \leq \: 35w + 10

Add 16 to both sides

That's

36w + 16 - 16 \leq \: 35w + 10 + 16 \n 36w \leq35w + 26

Subtract 35w from both sides

We have

36w - 35w \leq35w - 35w + 26 \n

We have the final answer as

w \leq \: 26

√(2) ^( √(7) )use a calculator to find an approximation for each power. give the maximum number of decimal places that your calculator displaysround this value to ,7 decimal places,.

Answers

We are given the following expression

\sqrt[]{2}^{\sqrt[]{7}}

Here the base is √2 and its power (exponent) is √7

The value of this expression can easily be calculated using any scientific calculator.

The maximum number of decimal places depends upon the type of calculator you use.

\sqrt[]{2}^{\sqrt[]{7}}=2.50164253682

Let us round this value to 7 decimal places.

\sqrt[]{2}^{\sqrt[]{7}}=2.5016425

Consider the quadratic function f(x) = x2 – 8x – 4. What is the value of the leading coefficient?8 оооо
4

Answers

Answer:

x = 4 + 2 sqrt(5) or x = 4 - 2 sqrt(5)

thus :

8

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 8 x - 4 = 0

Hint: | Solve the quadratic equation by completing the square.

Add 4 to both sides:

x^2 - 8 x = 4

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 16 to both sides:

x^2 - 8 x + 16 = 20

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 4)^2 = 20

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 4 = 2 sqrt(5) or x - 4 = -2 sqrt(5)

Hint: | Look at the first equation: Solve for x.

Add 4 to both sides:

x = 4 + 2 sqrt(5) or x - 4 = -2 sqrt(5)

Hint: | Look at the second equation: Solve for x.

Add 4 to both sides:

Answer: x = 4 + 2 sqrt(5) or x = 4 - 2 sqrt(5)
