What is 59.69 written in expanded form

Answers

Answer 1

Final answer:

The expanded form of 59.69 is 50 + 9 + 0.6 + 0.09.

Explanation:

59.69 written in expanded form can be expressed as:

50 + 9 + 0.6 + 0.09

5 * 10 + 9 * 1 + 0.6 * 0.1 + 0.09 * 0.01

5 * 10 + 9 * 1 + 6 * 0.1 + 9 * 0.01

50 + 9 + 0.6 + 0.09

Therefore, the expanded form of 59.69 is 50 + 9 + 0.6 + 0.09.

Answer 2

Final answer:

The number 59.69 written in expanded form is 50 + 9 + 0.6 + 0.09. Each term represents a digit according to its place value, with tens, ones, tenths, and hundredths places accounted for respectively.

Explanation:

Writing the number 59.69 in expanded form means expressing each digit according to its place value. Expanded form is a way of writing numbers to see the math value of individual digits. The number 59.69 would be broken down as follows:

50 + 9 + 0.6 + 0.09

Each term represents a digit in the number: '5' is in the tens place, so it is represented as 50; '9' is in the ones place, so it is simply 9; '6' is in the tenths place, so it is represented as 0.6; '9' is in the hundredths place, so it is represented as 0.09.

When performing calculations, particularly in subjects such as chemistry, scientific notation is often used to express large or tiny numbers efficiently. For example, to enter a number in scientific notation into a calculator, you must know the correct process, which can vary based on the calculator model. Consulting the instructor or the calculator's manual is advisable if there are any doubts.

Furthermore, working with scientific notation involves understanding how to properly write and interpret the exponents, which indicate how many places the decimal point has been moved.

Need quick help please?! Using the Angle Bisector Theorem solve for x.
Show all work.

Answers

From the angle bisector theorem;
15/3= (4x+1)/5
solving for x;
4x+1 = 25
4x= 24
x= 6

Using the Angle Bisector Theorem solve for x.

The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

As, we see the figure, AD bisects angle A

So, Applying Angle Bisector theorem, we get,

[tex] \frac{AC}{CD} =\frac{AB}{BD} [/tex]

[tex] \frac{AC=15}{CD=3} =\frac{AB=(4x+1)}{BD=5} [/tex]

[tex] \frac{15}{3} =\frac{4x+1}{5} [/tex]

15 divide by 3 gives 5

So, we have

5=[tex] \frac{4x+1}{5} [/tex]

To get rid of fractions let us multiply by 5 on both sides

5*5=[tex] \frac{5*(4x+1)}{5} [/tex]

25=[tex] \frac{1*(4x+1)}{1} [/tex]

25=4x+1

To solve for x, let us subtract 1 from both sides

25-1=4x+1-1

24=4x+0

Or, 4x=24

To solve for x, let us divide by 4 on both sides

[tex] \frac{4}{4}x=\frac{24}{4} [/tex]

What transformations of the parent function f(x) = |x| should be made to graph, f(x) = - |x| + 5?

Answers

To solve this problem, you must follow these steps:

1. Multiply the graph by -1 (That will reflect the function towards the -y axis).

2. Add 5. That will move the function upwards and you will obtain y=5 as its cut point with the y axis.

You can know the graph of a function by knowing the graph of the function "father" and applying the corresponding transformations, until turning it into the function studied.

The graph of the function f(x)=|x| has the shape of a cone that passes through the point (0,0).

What is the domain of the square root function graphed below?

Answers

Answer:

x ≥ 0

Step-by-step explanation:

The function is graphed starting at 0 and going up the positive x-axis.

These are numbers that are greater than 0; thus the domain is greater than or equal to 0, or

x ≥ 0

The domain of the function is (d) x >= 0

How to determine the domain?

From the graph, we have the following highlight:

The x values of the function starts at 0 and extends the right0 is inclusive of the x values

Since 0 is inclusive, we make use of the greater than or equal to inequality

Hence, the domain of the function is (d) x >= 0

A 60 cm rope is tied to the handle of a bucket which is then whirled in a vertical circle.

Answers

the complete question in the attached figure

a) we know that
T - mg = mv^2/r
The net forces equal the mass times the centripetal acceleration
So
T=50 N
m=3 kg
r=0.60 m
v = sqrt((T-mg)r/m) = sqrt((50-(3*9.8))*(.60)/3) = 2.03 m/s

the answer part a) is 2.03 m/s

b) At the top the equation becomes T+mg=mv^2/r
but here the critical speed occurs when T = 0
so the critical speed is v = sqrt(rg) = sqrt (.60*9.80) = 2.42 m/s

the answer part b) is 2.42 m/s

Final answer:

The scenario described in the question involves using a rope to whirl a bucket in a vertical circle. This relates to the physics concepts of centripetal force, tension in the rope, and gravity. The tension in the rope provides the centripetal force needed for the curved path of the bucket, and the scenario implies a constant speed and a counterbalance between tension and gravity at the highest point of the circle.

Explanation:

The question involves a principle of physics known as centripetal force, which is the force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body, towards the fixed point of the instantaneous center of curvature of the path.

In this case, the 60 cm rope tied to the bucket and whirled in a vertical circle becomes a system where the bucket, the force of gravity, and the tension in the rope all play a part. When the bucket is whirled, it experiences a centripetal force that keeps it moving in a circle. This force comes from the tension in the rope, which always pulls the bucket towards the center of the circle (the hand holding the rope). Hence, there are two key forces in this scenario - the force of gravity, pulling the bucket downward, and the tension in the rope providing the centripetal force.

Since the question does not state otherwise, we can reasonably assume that the movement is steady, implying the speed of the bucket is constant. In such a case, the swinging bucket will rise to a certain point, where the tension in the rope and the gravity cancel each other, causing the bucket to start falling back to the other side, therefore, forming the vertical circular path.

The 1997 value of an object was $9500. In 2012, it was worth $5000. The annual percent of decay has been constant. What is the annual percent of decay? A) 1.19% B) 2.19% C) 3.19% D) 4.19%

Answers

Hello,

Here is your answer:

The proper answer to this question is option D "4.19%".

Your answer is D.

If you need anymore help feel free to ask me!

Hope this helps!

Answer:

The answer is D.

Step-by-step explanation:

If the object starts with a value [tex]V_0[/tex], and a annual percent of decay d, after a year the value will be

[tex]V_1 = V_0 * d[/tex]

after 2 years, taking now [tex]V_1[/tex] as the starting value

[tex]V_2 = V_1 * d = V_0 * d * d [/tex]

[tex]V_2 = V_0 * d^2 [/tex]

and so on, after n years the value will be:

[tex]V_n = V_0 * d^n[/tex]

Now, in 1997 the value was $9500, in 2012 the value was $5000. Between 1997 and 2012 there are 15 years, so, our equation will be:

[tex] \$5000 = \$ 9500 * d^{15}[/tex]

Working it a little

[tex] \frac{\$5000}{\$ 9500} = d^{15}[/tex]

[tex] (\frac{\$5000}{\$ 9500})^{1/15} = d[/tex]

[tex] (0.5263})^{1/15} = d[/tex]

[tex] 0.9581 = d[/tex]

This mean that, after a year, the value will be at 95.81 %, this is, a decay rate of 4.19%.

A wire 320 in. long is cut into two pieces. one piece is formed into a square and the other into a circle. if the two figures have the same area, what are the lengths of the two pieces of wire (to the nearest tenth of an inch)? circle in square in

Answers

The area of a circle can be computed from the circumference (c) as
.. Acircle = c^2/(4π)

The area of a square can be computed from its perimeter (p) as
.. Asquare = (p/4)^2 = p^2/16

These are equal when
.. Acircle = Asquare
.. c^2/(4π) = p^2/16
.. c^2/p^2 = (4π)/16
.. c/p = (√π)/2

The total length is 320 inches, so ...
.. wire for circle = ((√π)/2)/(1 +(√π)/2)*320 in ≈ 150.3 in
.. wire for square = 320 in - wire for circle ≈ 169.7 in

_____
In the graph, (x, y) represents (circle wire, square wire).

Final answer:

The lengths of the two pieces of wire, when one is formed into a square and the other into a circle with equal areas, are approximately 186.3 inches and 133.7 inches respectively.

Explanation:

To solve this problem, we first need to understand that the total perimeter of both the square and the circle made from the wire lengths equal to the original wire length, which is 320 inches. Suppose the length of the wire used for the square is 'a' and the length for the circle is 'b'. So, 'a + b = 320' inches.

Given that, the areas of both the square and the circle are equal. The area of a square is side^2 and the side of our square will be 'a/4' (since a square has four equal sides) and the area of a circle is πr^2, with the circumference being 2πr or 'b' in this case, so the radius is 'b / (2π)'.

Setting these two areas equal gives us the equation '(a/4)^2 = π * (b/ (2π))^2'. Solving this system of equations, we find that 'a' is approximately 186.3 inches and 'b' is approximately 133.7 inches.

Correct answer.
y^2-2y+3

Answer:

y²-2y+3

Step-by-step explanation:

We write the dividend, y³-y²+y+3, under the box and the divisor, y+1, to the left of the box.

We first divide y³ by y; this is y². We write this above the box, over -y². We multiply the divisor by y²:

y²(y+1) = y³+y²

This goes under the divisor. We then subtract:

(y³-y²)-(y³+y²) = -2y². We then bring down the next term, y; this gives us -2y²+y.

We then divide -2y² by y; this is -2y. This goes above the box beside the y² in the quotient. We then multiply the divisor by -2y:

-2y(y+1) = -2y²-2y

We now subtract:

(-2y²+y)-(-2y²-2y) = 3y. We bring down the last term, 3; this gives us 3y+3. We divide 3y by y; this is 3. This goes beside the -2y in the quotient. We then multiply this by the divisor:

3(y+1) = 3y+3. We then subtract: (3y+3)-(3y+3) = 0

This makes the quotient y²-2y+3.

ANSWER:
The circumference is 40.82 yards, estimated to 41 yards.

Hope this helps! :)

Final answer:

To estimate the circumference of a circle with a diameter of 13 yards, use the formula C = π * d where π is approximated as 3.14. The estimated circumference is 40.82 yards.

Explanation:

To estimate the circumference of a circle that has a diameter of 13 yards, you can use the formula for the circumference of a circle, which is π times the diameter (C = π * d). The value of π (pi) can be rounded to 3.14 for convenience in calculation. Using this rounded value of π:

Circumference = 3.14 * 13 yards= 40.82 yards

Therefore, the estimated circumference of the circle is 40.82 yards.
