What is this number? +1.25 E -19

The percent change from 36 to 63 is calculated using the formula: [(New value - Original value) / Original value] x 100. The percent change in this case is 75%.

To find the percent change from the first value to the second, use the following formula:

Percentage change = [(New value - Original value) ÷ Original value] × 100
In this case, the original value is 36 and the new value is 63. So, the change in value is 63 - 36 = 27.

Next, divide the change by the original value: 27 ÷ 36 = 0.75.

To convert this to a percentage, multiply by 100: 0.75 × 100 = 75%.

Therefore, the percent change from 36 to 63 is 75%.

Answer: The answer is 137°.

Step-by-step explanation: Given that the quadrilateral ABCD is inscribed in a circle, where measure of angle C is 43°. We are to find the measure of ∠A.

Since the quadrilateral ABCD is inscribed in a circle, so it will be a cyclic quadrilateral. Also, the sum of opposite angles of a cyclic quadrilateral is 180°.

Therefore, we have

[tex]\angle A+\angle C=180^\circ\\\\\Rightarrow \angle A+43^\circ=180^\circ\\\\\Rightarrow \angle A=180^\circ-43^\circ\\\\\Rightarrow \angle A=137^\circ.[/tex]

Thus, the required answer is 137°.

WZ is tangent to circle O at point B. The measure of [tex]\angle OBZ[/tex] is [tex]90^{\circ}[/tex].

line wz is tangent to circle O at point B.

We have to find out the measure of [tex]\angle OBZ[/tex].

A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of Tangency.  

The tangent to a circle is perpendicular to the radius at the point of tangency.

Here in circle O, WZ is the tangent which touches the circle at point B,

so B is the point of tangency and the [tex]\angle OBZ[/tex] is [tex]90^{\circ}[/tex].

Hence the correct option is B. [tex]90^{\circ}[/tex]

The answer is: D)quadratic trinomial

The solution is Option D.

The quadratic trinomial is given by A = 4x² + 3x + 5

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4x² + 3x + 5   be equation (1)

Car travels at speed of 44 feet per second. Converted to miles per hour, it's 30 mph. In 4 hours, it travels 120 miles, using the conversion factor 1 mile = 5280 feet.

To find the car's speed in miles per hour, you can use the conversion factor:

1 mile = 5280 feet

So, first, we need to convert the car's speed from feet per second to miles per hour.

Find out how many feet the car travels in an hour, and then we'll convert that to miles:

1 hour = 60 minutes

1 minute = 60 seconds

So, in 1 hour, there are 60 minutes × 60 seconds = 3600 seconds.

Now, if the car is traveling at a speed of 44 feet per second, in 1 hour, it would travel:

44 feet/second × 3600 seconds/hour = 158,400 feet/hour

Now, convert this to miles:

158,400 feet/hour / 5280 feet/mile = 30 miles/hour

So, the car's speed is 30 miles per hour.

To find out how many miles the car will travel in 4 hours at this speed:

4 hours × 30 miles/hour = 120 miles

The car will travel 120 miles in 4 hours.

Therefore, speed of the car is 30 miles/hour and it travels 120 miles in 4 hours.

3. 11

Step-by-step explanation:

Just did the assignment.

Using the form of a quadratic equation f(x) = ax^2 + bx + c, we can derive an equation for each of three given points (10,20,30 kph and their corresponding costs). Solving these simultaneously we would get the particular equation representing the situation. We could then apply this to calculate costs at various speeds including checking if it is possible to spend only 10 cents/km, determining an optimal speed range for a 13 cents/km cost, and finding the optimal speed and cost per km.

To write a particular function that represents this scenario, we can set up three equations using the general form of a quadratic equation, which is f(x) = ax^2 + bx + c. In this case, our x-values are the speeds (10, 20, and 30 kph) and our f(x) values are the corresponding costs (28, 21, and 16 cents/km).

Substitute these values into the equation f(x) = ax^2 + bx + c, we get three equations:
100a + 10b + c = 28
400a + 20b + c = 21
900a + 30b + c = 16

By solving the system of equations, we could find the values of a, b and c. Then we would substitute the speed into the function to calculate the cost at 150 kph, and to find the speed range for a cost of 13 cents/km and check if it is possible to spend only 10 cents/km. Finally, the optimal speed and cost per km would be represented by the minimum point of the function, which in the case of a parabola occurs at x = -b/2a.

Answer:

The money spend on gas in one week = 46.13 Euro

The money spend on gas in one week = $58.12

Step-by-step explanation:

1 week = 7 days

You drive 107 km per day.

Kilometer driven for 7 days = 7 *107 = 749 kilometers.

Now let's convert kilometers to miles.

1 mile = 1.60934 kilometers

We have to divide 749 km by 1.60934.

So, 749 km = 465.41 miles.

Car mileage is 42 miles / gallon.

We need to find the number of gallons of gas needed to travel 465.41 miles.

So, we have to divide 465.41 miles by 42.

The number of gallons of gasoline needed = [tex]\frac{465.41}{42} = 11.08 gallons[/tex]

cost of 1 .10 Euros per liter.

Now we have to convert 11.08 gallons to liters.

1 gallon = 3.78541 liters.

So we have to multiply 11.08 by 3.78541

11.08 gallons = 41.94 liters.

Now to find the cost, we need to multiply 41.94 liters by 1.10 Euro.

The money spend on gas in one week = 46.13 Euro

To convert the cost in dollars.

1 euro = 1.26

We need to multiply 46.13 by 1.26

The money spend on gas in one week = $58.12

Step-by-step explanation:

The statement 'Angle 2 and Angle 3 are vertical angles' can be true depending on their position, as vertical angles are those directly opposite from each other at the intersection of two lines.

The question is asking about vertical angles. Vertical angles are pairs of non-adjacent angles formed when two lines intersect. This means they are the angles that are directly opposite from each other where the two lines intersect. So if Angle 2 and Angle 3 are directly opposite each other at the point where two lines cross, then they are indeed vertical angles. So, the statement 'Angle 2 and Angle 3 are vertical angles' can be true depending on their placed positions.
