Answer:

Step-by-step explanation:

The place value of the 5 in the number 2.35 x 104 is ten thousand.

In scientific notation, the number 2.35 x 104 represents 2.35 times 10 to the power of 4. The number 10 to the power of 4 is 10,000, so the digit 5 is in the ten thousand place. The ten thousand place has a value of 10,000, so the 5 in 2.35 x 104 has a place value of 10,000.

So, the place value of the 5 in 2.35 x 104 is ten thousand.

a) The amount of the supplies is $70

b) The number of the plants is 3

c) The rate of change is 1/20.

A proportional relationship is a mathematical relationship between two variables where their ratio is constant. In other words, as one variable increases or decreases, the other variable also increases or decreases in the same ratio.

We have to note that we can read up the relationship from the graph. The amount of the supplies for 9 plants is $70. If the total budget is $60 then we can only have three plants. The rate of change is therefore 1/20.

The Angle C is 83.2°

The Law of Cosines, also known as the Cosine Formula, is a mathematical relationship that relates the lengths of the sides of a triangle to the cosine of one of its angles. The law states that in a triangle ABC with sides a, b, and c opposite to angles A, B, and C, respectively, the following equation holds:

c^2 = a^2 + b^2 - 2ab cos(C)

where "cos" represents the cosine function. The Law of Cosines can be used to find missing sides or angles in a triangle when given sufficient information. It is widely used in geometry, trigonometry, and engineering. The Law of Cosines is an extension of the Pythagorean theorem and can be used when the triangle is not a right triangle. It is a powerful tool for solving a variety of problems in a wide range of fields.

To find the angle C in triangle ABC, you can use the Law of Cosines. The Law of Cosines states that in a triangle ABC with sides a, b, and c and opposite angles A, B, and C, the following equation holds:

c² = a² + b² - 2abcos(C)

In this case, a = 20 cm, b = 29 cm, and c = 24 cm, and we are given that angle BAC = 82 degrees. Using this information, we can calculate cos(C) as follows:

cos(C) = (a² + b² - c²)/(2ab) = (20² + 29² - 24²)/(2×20×29) = 0.2618

Finally, we can use the inverse cosine function (arccos) to find angle C:

C = arccos(cos(C)) = arccos(0.2618) = 83.2 degrees (rounded to one decimal place).

So, angle C in triangle ABC is approximately 83.2 degrees.

Answer:

(x - 6)² + y² = 36 and x2 + (y + 6)2 = 36.

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is given by:

(x - h)² + (y - k)² = r².

So, for a circle with a diameter of 12 units, the radius is 6 units.

For the center of the circle to lie on the y-axis, the x-coordinate, h, is 0.

So, the equation for a circle with center (0, k) and radius 6 units is:

(x - 0)² + (y - k)² = 6²

x² + (y - k)² = 36

Two possible values for the y-coordinate of the center, k, that would give us two different circles are k = 6 and k = -6.

So, the two equations are:

x² + (y - 6)² = 36

and

x² + (y + 6)² = 36.

The size of angle ACB to the nearest degree is 88 degree.

Construction Steps:

Create a line segment BC with the property AC = 4 cm.

Draw two arcs that meet at point A by using B as the centre and a radius of 4 cm, and C as the centre and a radius of 7 cm.

Join AB and AC now. Consequently, the necessary triangle is ABC.

With the use of a compass, draw a line segment AB = 7 cm from A, cutting an arc AC = 4 cm.

Cut an arc of 3 cm from point B.

Answer:

  (a)  y = x/3 -1

Step-by-step explanation:

You want the equation of the line graphed showing points (3, 0) and (6, 1).

The slope of the line is its "rise" divided by its "run." Here, the points are 3 units apart horizontally, and 1 unit vertically, with the line going up to the right. That means ...

  slope = rise/run = +1/+3 = 1/3

The slope-intercept form of the equation for a line is ...

  y = mx +b . . . . line with slope m and y-intercept b

The slope of 1/3 means the coefficient of x will be 1/3. There is only one answer choice like that:

  y = x/3 -1

Answer:

Step-by-step explanation:

To find the number of hours David has to work at each job, we can set up an equation. Let's say David works x hours at the first job and y hours at the second job. Then, we have:

14x + 11y = 1000

Next, we need to find the possible combinations of x and y that satisfy this equation. To do this, we can use trial and error, or use the substitution method. Let's use the latter method. Solve for x in terms of y:

14x = 1000 - 11y

x = (1000 - 11y) / 14

Now, we can substitute this expression for x into the original equation to get a new equation in terms of y:

11y = 1000 - 14x

y = (1000 - 14x) / 11

We can use this equation to find possible values of y. For example, if x = 40 hours, then y = (1000 - 14 * 40) / 11 = (1000 - 560) / 11 = (440) / 11 = 40. So, David could work 40 hours at the first job and 40 hours at the second job to earn $1000.

We can repeat this process for other values of x to find more combinations. Some possible combinations of the numbers of hours David could work at each job to earn $1000 are:

40 hours at the first job and 40 hours at the second job

45 hours at the first job and 35 hours at the second job

50 hours at the first job and 30 hours at the second job

55 hours at the first job and 25 hours at the second job

60 hours at the first job and 20 hours at the second job, etc.

Answer:

(-infinity,-1)U(-1,infinity)

Step-by-step explanation:

plug in the number where the piecewise function changes which is -1 and 1

(-1)^2-(-1)-2 =0

(-1)=-1

These aren't equal so the function  is discontinuous at x = -1 because of a jump

(1) = 1

-2(1) + 3 = 1

These are equal so the function is continuous at x = 1

So from negative infinity to -1 the function is continuous and from -1 to infinity

The total commission the realtor earns is given by the equation A = $ 9375

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total commission amount the realtor earns be represented as A

Now , the equation will be

The percentage of commission = 1.25 %

The total amount for the 2 homes = $ 750,000

So , the amount of commission A = percentage of commission x total amount for the 2 homes

Substituting the values in the equation , we get

The amount of commission A = ( 1.25 / 100 ) x 750,000

On simplifying the equation , we get

The amount of commission A = 0.0125 x 750,000

The amount of commission A = $ 9375

Hence , the amount of commission is $ 9375

The total surface area painted black = 90.5 square feet to the nearest tenth.

A cone is a three-dimensional geometric form with a flat base and a smooth, tapering apex or vertex. A cone is made up of a collection of line segments, half-lines, or lines that link the base's points to the apex, which is a common point on a plane that does not include the base.

Given:

Three large cones hang from the ceiling in an office building in front of a bank of windows.

The height of each cone is 12 feet, and the circumference of the base of each cone is 8π feet.

The base and 40% of the lateral surface of each cone is painted red, and the rest of each cone is painted black.

Circumference of the base of the cone = 8π feet.

2πr = 8π

πr = 4π

The surface area of the cone = πr x height

The surface area of the cone = 12 x 4π

The surface area of the cone = 48π.

The total surface area painted black = 60% of 48π.

The total surface area painted black = 90.5 square feet to the nearest tenth.

The amount invested in savings with annual interest rate of 6% and 10% is $398200 and $199100.

Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.

Let S be his savings.

He divided S into x that goes at 6% and y at 10%

As he put twice as much at the lower-yielding one, x = 2y.....(1)

Simple interest is given by: Amount x interest x time

Thus,

SI₁ = x . 0.06 . 1 = 0.06x

S I₂ = y. 0.10 . 1 = 0.10y

As x = 2y, I₁ = = 0.06 . 2y = 0.12y

As we know that the annual interest was $3982

SI₁ + SI₂ = 3982

0.12y + 0.10y = 3982

0.22y = 3982

y = 3982/0.22
