Answer:

one hundred twenty-five and sixty-five thousandths

Step-by-step explanation:

The 125 part is simply one hundred twnty five.

The .065 has the 5 in the thousandths place, so it is sixty-five thousandths.

Answer: one hundred twenty-five and sixty-five thousandths

Answer:

2.5

Step-by-step explanation:

i am not absolutely sure but according to me it is right

ANSWER:

2.45

Expalnation:

If you add/subtract 0.75 to the corrct side, you'll get 2.45.

3.2-2.45=0.75

2.45-1.7=0.75

Hence, this is the corrct answer.

There are 2 tangent lines that pass through the point

[tex]y=\frac{1}{(-1+\sqrt{3)^2} } (x-1)+2[/tex]

and

[tex]y=\frac{1}{(-1-\sqrt{3)^2} } (x-1)+2[/tex]

Explanation:

Given:

[tex]y=\frac{x}{x+1}[/tex]

The point-slope form of the equation of a line tells us that the form of the tangent lines must be:

[tex]y=m(x-1)+2[/tex] [tex][1][/tex]

For the lines to be tangent to the curve, we must substitute the first derivative of the curve for [tex]m[/tex]:

[tex]\frac{dy}{dx} =\frac{d(x)}{dx}(x+1)-x^\frac{d(x+1)}{dx} \\ \\[/tex]

[tex]\frac{dy}{dx} =\frac{x+1-x}{(x+1)^2}[/tex]

[tex]\frac{dy}{dx}= \frac{1}{(x+1)^2}[/tex]

[tex]m=\frac{1}{(x+1)^2}[/tex] [tex][2][/tex]

Substitute equation [2] into equation [1]:

[tex]y=\frac{x-1}{(x+1)^2}+2[/tex] [tex][1.1][/tex]

Because the line must touch the curve, we may substitute [tex]y=\frac{x}{x+1}:[/tex]

[tex]\frac{x}{x+1}=\frac{x-1}{(x+1)^2}+2[/tex]

Solve for x:

[tex]x(x+1)=(x-1)+2(x+1)^2[/tex]

[tex]x^2+x=x-1+2x^2+4x+2[/tex]

[tex]x^2+4x+1[/tex]

[tex]x\frac{-4±\sqrt{4^2-4(1)(1)} }{2(1)}[/tex]

[tex]x=-2[/tex] ± [tex]\sqrt{3}[/tex]

[tex]x=-2[/tex] ± [tex]\sqrt{3}[/tex] [tex]and[/tex] [tex]x=-2-\sqrt{3}[/tex]

There are 2 tangent lines.

[tex]y=\frac{1}{(-1+\sqrt{3)^2} } (x-1)+2[/tex]

and

[tex]y=\frac{1}{(-1-\sqrt{3)^2} } (x-1)+2[/tex]

Answer:

A Rectangle should fit all these rules.

Answer:

-10 + 28i

Step-by-step explanation:

Multiply the binomials ↓

1*5+3i+(5i*5)+(5i*3i)

Simplify ↓

5+3i+25i+15i²

Combine like terms ↓

5+28i+15i²

Now, since i is the square root of -1, i² (i times i) is equal to -1 ↓

5+28i-15

28i-15+5

28i-10

Answer:

Between 0 and 1 there is 12, between 1 and 2 there is 112=3/2, and so on. In fact, there are infinitely many fractions between any two whole numbers. Let's see why. Between 0 and 1 there are also 13, 14, 15, and any number that can be written as 1n where n is some whole number.

Answer:

Option B is the answer

am not really sure though

Answer:

1. No sol.

2. One Sol. x=4

3. One Sol. w=22 1/2

Step-by-step explanation:

1.

Group like terms:

4+3p=6p-3p+5

Add similar elements (6p-3p=3p):

4+3p=3p+5

Subract 4 from both sides:

4+3p-4=3p+5-4

Simplify:

3p=3p+1

Subtract 3p from both sides:

3p-3p=3p+1-3p

Simplify:

0=1

There is no solution.

2.

One Sol. x=4

Switch sides:

3x-2=10

Add 2 to both sides:

3x-2+2=10+2

Simplify:

3x=12

Divide both sides by 3:

3x/3=12/3

Simplify:

x=4

There is a solution.

3.

One Sol. w=22 1/2

Subtract 7 from both sides:

2/3w+7-7=22-7

Simplify:

2/3w=15

Multiply both sides by 3:

3*2/3w=15*3

Simplify:

2w=45

Divide both sides by 2:

2w/2=45/2

Simplify:

w=22 1/2

There is one sol.

Answer:

300 lbs

Step-by-step explanation:

We know that Larry bench pressed 200 lbs last week, and that he is supposed to increase by 15%. We know that any number times one is that same numbers. That means a number that is increaseing has to be greater than 1. So, we have to convert 15% into a decimal. That is 0.15. That plus one is 1.15. Now we just have to multiply 1.15 with 200. We get 300.

Answer:

Option D, [tex]f =[/tex] ± [tex]4.12[/tex]

Step-by-step explanation:

Step 1:  Subtract 153 from both sides

[tex]-9f^2 + 153 = 0[/tex]

[tex]-9f^2 + 153 - 153 = 0 - 153[/tex]

[tex]-9f^2 = -153[/tex]

Step 2:  Divide both sides by -9

[tex]\frac{-9f^2}{-9} = \frac{-153}{-9}[/tex]

[tex]f^2 = 17[/tex]

Step 3:  Square root both sides

[tex]\sqrt{f^2} = \sqrt{17}[/tex]

[tex]f =[/tex] ± [tex]4.12[/tex]

Answer: Option D, [tex]f =[/tex] ± [tex]4.12[/tex]

Answer:

152 in^2

Step-by-step explanation:

If you take the left side and consider it a whole rectangle, you can calculate the area of that triangle to be 80. Using the same method, you can find the area of the rectangle of the right to be 72. Then add them together.

80 + 72 = 152 in^2

Answer: 11.4

Step-by-step explanation:  In the fraction 57/5, 57 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 57/5 is same as "57 divided by 5" or "57 ÷ 5".

When we calculated 57 divided by 5, we found that 57/5 in decimal form is:57 ÷ 5 = 11.4 Therefore, the decimal form of 57/5 is 11.4

Answer:

4620.

Step-by-step explanation:

The number of combinations of 3 men from 9

= 9!/(9-3)!3!

=  9*8*7/3*2*1

= 84 ways.

The number of combinations of 2 women from 11

= 11!/11-2)!2!

=  11*10/2*1

= 55 ways.

So the total number of ways  of men and women in the committee

= 84*55

= 4620.

Answer:

f(-2) = -3

Step-by-step explanation:

Step 1. Find equation

Step 2. Plug (-2) into f(x)

m, rise/run = (-2-0)/(0-4) = -2/-4 = 1/2

b, y-intercept = (0, -2)

y = 1/2x - 2

f(-2) = 1/2(-2) - 2

f(-2) = -1 - 2

f(-2) = -3

If you want to cheat, simply look for x = -2 on the graph and see where it touches the line. Then match the y-value and BOOM: (-2, -3), f(-2) = -3

Answer:

Emily, use the circle formula to solve this (x−a)^2 + (y−b)^2 = r^2

Step-by-step explanation:

where  a  and b are the center off sets in the x and y directions , repspectively.  

(x - 5)² + (y + 2)² =81/4

So you now know,  the center is at   (x,y) = ( 5, 2)

and the radius is   [tex]\sqrt{\frac{81}{4} }[/tex]  ,  why is is square rooted ?  you ask.

because in our formula above it's   r^2  .. so we need to square root it to find it's value.

[tex]\frac{\sqrt{81} }{\sqrt{4} }[/tex]  =  [tex]\frac{9}{2}[/tex]  =  4.5  rounded to two decimals    4.50 but not necessary

Answer:

Using 3.14 for pi

SA =1808.64 cm^3

Using the pi button

SA =1809.557368 cm^3

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

We are given a radius of 12

SA = 4 pi ( 12) ^2

SA = 4 pi * 144

SA = 576 pi

Using 3.14 for pi

SA =1808.64 cm^3

Using the pi button

SA =1809.557368 cm^3
