The point on the graph at the function value f(x)=1 is x = -4/5

The equation of the function is given as:

f(x) = 2 - x4x + 6

Rewrite the rational function, properly as follows:

f(x) = 2 - x/4x + 6

When f(x) =  1, we have:

2 - x/4x + 6  = 1

Cross multiply

2 - x = 4x + 6

Collect the like terms

4x + x = 2 - 6

Evaluate the like terms

5x = -4

Divide by 5

x = -4/5

Hence, the point on the graph at the function value f(x)=1 is x = -4/5

Each side of the larger trapezoid is 5 times each corresponding side of the smaller trapezoid.

The percent of error to the nearest hundredth percent is 16.82 % when the estimated mass is 500 g and the actual mass is 428 g.

We are given that:

Some students estimated that a small block of Copper will have the mass = 500 g

Estimated mass = 500 g

But now, the actual mass was found out and it came = 428 g

Actual mass = 428 g

The error in estimation was:

Error = 500 g - 428 g

Error = 72 g

Percentage of error = 72 g / 428 g × 100

Percentage of error = 7200 g / 428 g %

Percentage of error = 16.82 %

Therefore, we get that the percent of error to the nearest hundredth percent is 16.82 %.

Answer:

-5/40

Step-by-step explanation:

(1/40)(4) + (10/40)(2) - (29/40)(1)

The greater proportion is 36/104 since 34.62% is greater than 32.11%.

A % is a relative figure that represents the hundredth part of any amount. One percent (symbolized 1%) indicates the hundredth part; consequently, 100 percent represents the complete amount and 200 percent specifies times the supplied quantity.

Given fractions are = 35/109 and 36/104

finding the greater fraction we express them as a percentages:

So the first fraction will be:

(35/109 ) * 100

= 3500/109

= 32.11%

For the second equation:

(36/104) * 100

= 3600/104

= 34.62%

The greater proportion is 36/104 since 34.62% is greater than 32.11%.

The greatest common factor for 4x³+16x² +8x is 4x(x2- 4x - 2).

This solution focuses on simplification:

4x(x2-4x-2)

(4(x3)-24x2)-8x

(22x3-24x2) -8x

Take similar factors aside:

4x3-16x2-8= 4x(x2-4x-2)

Factoring  x2 - 4x - 2

x2 is the initial term, and it has a coefficient of 1.

The coefficient of the intermediate term, which would be -4x, is 4.

"The constant," the final term, is -2.

Multiply the constant by the coefficient of the first term. 1  -2 = -2

The second step is to find two -2 factors whose sum is equal to the -4 coefficient of the middle word.

-2 + 1 = -1

-1 + 2 = 1

No two of these factors can be discovered!!

Trinomial cannot be factored.

Hence,  The greatest common factor is  4x(x2- 4x - 2).

The magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart is 2N.

The repulsive force between two charges = (k q₁ q₂)/r²

q₁ q₂ are the charges

r is distance between the charges

k= 9×10⁹ Nm²C²

F= (500μC) (+100μC)9×10⁹/25

A movement between two charges that are same or comparable is referred to as repulsion. The tension between two electrons (negative charge). Two charges of a different sort are drawn toward one another by the force of attraction, which is defined as "a force between two charges that are distinct or different."

At a distance, magnetism is an attractive or repulsive force. The repulsive force gives rise to a metric that measures how a system's gravitational mass changes. According to the force-based approach, the forces that attract and repel other atoms come from their subatomic arrangement and control how they behave.

a) James have to invest 5,248 dollar and 89 cent to earn $7,592 amount of interest in 16 years .

b) Principal amount of money , which is to be invested is 4158 dollar and 46 cent .

This is a problem from  simple interest system. We have to use the given formula, I = p.r.t to solve this problem.

a) James wants to have earned $7,592 amount of interest in 16 years. So, here the time period is 16 years and the interest rate is 9.04% and we have to find the principal amount.

I = p. 16. ( 9.04% )

Amount of interest = $ 7592

Time period = 16 years

rate of interest = 9.04 %

7592 = p . 16 . ( 904/10000 )

p = 75920000/ 16 . 904

or , p = $5,248.89 ≈ $5249

James have to invest $5,248.89 to earn $7,592 amount of interest in 16 years .

b) We have to use the given formula to find the value of p or the principal amount of money .

Rate of interest = 8.63% or .0863

time period = 24 years

Interest = $8613

The required volume of the box is given as 936 cubic centimeters.

Given that, A box of Tyler's favorite snack, Cheesy Snaps, is 13 centimeters tall and 6 centimeters wide. It has twice as long as it is wide.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
height  = 2 × width
height = 2 × 6 = 12
The volume of the box = length × width  × height
                             = 13 × 6 × 12 = 936

Here, we need to find the area of the shaded region.

To do this, we will subtract the area of the smaller rectangle from the larger one.

The area of the larger rectangle = 8 × 15

= 120 square units

Now, the we have one side of the smaller rectangle which is 5, the other side will be (15 - 4 - 1) = 10 units.

The area of the smaller rectangle = 10 × 5

Using relations in a right triangle, it is found that the distance between the towns is of 15 km.

The relations in a right triangle are given as follows:

For the first town, we have that:

Hence:

xA = 10 x tan(37º).

xA = 7.5 km.

For the second town, we have that:

Hence:

tan(66º) = xB/10

xB = 10 x tan(66º).
