Step-by-step explanation:

The ordered pairs that defines the solutions of the system of equations f(x) = x² - 2x + 3; f(x) = -2x + 7 are

(2, 3) and (-2, 11)

Ordered pairs refers to the arrangement of 2 numbers in the form (a, b)

As used in the cartesian coordinates

a refers to a point in the x direction b refers to a point in the y direction

Solutions of the system of equation is the points where the straight line intersect the curve or where the two graphs intersect.

the point of intersection

x² - 2x + 3 = -2x + 7

x² - 2x + 2x + 3 - 7 = 0

x² + 3 - 7 = 0

x² - 4 = 0

solving for x

x² = 4

x = √4

x = 2 OR -2

solving for y

For x = 2, y = -2 * 2 + 7 = 3

For x = -2, y = -2 * -2 + 7 = 11

hence we have the points to be (2, 3) and (-2, 11)

Nate's car was filled with 16 gallons of gas.

The concept is used in this is equations. An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. An equation is the set of variables, constants, and mathematical operations like addition, subtraction, multiplication, or division balanced by an equal sign. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.

As gas is $2. 09 per gallon at the gas station.

$2. 09 → per gallon

and Nate filled up his car and spent $33. 44.

$33. 44 for fully filled → how many gallons ?

So,

33.44 / 2.09 = 16 gallons.

Therefore, Nate filled 16 gallons gas in his car.

Answer:

The result of 6 divided by 9.51 is approximately 0.63.

Answer:

0.63091482649

Step-by-step explanation:

The formula becomes a times 1, which is merely a, when you swap out 0 for the exponent x. This is so because 1 equals any number raised to the power of 0. The value of a will always be the initial value for any function with this form since the initial value is the function's value with an input of 0.

By looking for an equation's constant, one can also locate initial values. Graph functions benefit from understanding the y-intercept.

Any number that is multiplied by 0 equals 1.

A number is equal to a number multiplied by 1.

The value of a multiplied by one will equal its starting value.

Given:

In a circle, two chords CE and DU intersect each other inside the circle at B.

Measure of arc CD = 185 degrees.

Measure of arc EU = 55 degrees.

To find:

The measure of angle CBD.

Solution:

Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.

Using Intersecting chords theorem, we get

[tex]m\angle CBD =\dfrac{1}{2}(arcCD+arcEU)[/tex]

[tex]m\angle CBD =\dfrac{1}{2}(185^\circ +55^\circ )[/tex]

[tex]m\angle CBD =\dfrac{1}{2}(240^\circ )[/tex]

[tex]m\angle CBD =120^\circ[/tex]

Therefore, the measure of angle CBD is 120 degrees.

Consider,

[tex]x + y = 46\\x = 46 -y[/tex]

→ (x+4) : (y +4) = 7:2

→ x+4/y+4 = 7/2

→ 46-y+4/y+4 = 7/2

→ 50-y/y+4 = 7/2

→7y +28 = 100-2y

→ 7y +2y = 100 -28

→ 9y = 72

→ y = 8

Now put y = 8 in eq(1) .

→ x = 46 - y

→ x = 46 - 8

→ x = 38

The percentages for this problem are calculated as follows:

The percentages in this problem are obtained applying proportions, multiplying the total amount by the decimal equivalent of the percentage.

Hence the amount that represents 100% of 36 seconds is obtained as follows:

1 x 36 = 36 seconds.

(as a percentage of 100% has a decimal equivalent of 1).

The amount that represents 25% of 36 seconds is obtained as follows:

0.25 x 36 = 9 seconds.

(as a percentage of 25% has a decimal equivalent of 1).

The percentage of 125% of 36 students can be obtained combining the two previous expressions as follows:

1.25 x 36 = 1 x 36 + 0.25 x 36 = 36 + 9 = 45 seconds.

Answer:

  about 0.04878 hours ≈ 2 minutes 56 seconds

Step-by-step explanation:

You want the time until a whale-watching boat and a whale meet if the boat is traveling south at 83 km/h and the whale is traveling north at 40 km/h when they start 6 km apart.

The speed at which the gap between the boat and the whale is closed is the sum of their respective speeds:

  closing speed = 83 km/h + 40 km/h = 123 km/h

The time it takes to close the 6 km gap is ...

  time = distance/speed

  time = (6 km)/(123 km/h) ≈ 0.04878 h

Converted to minutes and seconds, that is about ...

  0.04878 h ≈ 2 minutes 55.6 seconds

It will be about 2 minutes 56 seconds before the boat and whale meet.

Additional comment

NOAA recommends a distance of at least 100 yards be maintained between a boat and a whale. In some areas, the recommended distance is 400 yards when approaching head-on. The recommended boat speed is 15 knots or less, about 28 km/h.

The vertex of V(x) = 13x² - 184x + 5800 are at 7.08 + i19.9 Or  7.08 - i19.9.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

We know the graph of a quadratic equation is a parabola and the vertex of the parabola are the roots o the quadratic equation.

Given, V(x) = 325x² - 4600x + 145000.

V(x) = 13x² - 184x + 5800.  (we have factored out 25)

Now, By applying Sridhar acharya's formula,

x = [- b ± √(b² - 4ac)]/2a.

x = [184 ± √(33856 - 301600)]/26.

x =  [184 ± i√267744]/26.

x =  [184 ± i517.44]/26.

x = 7.08 + i19.9 Or  7.08 - i19.9.

Answer:

Step-by-step explanation:

To find the total number of miles Karime walks, we need to multiply the number of miles she walks each day by the number of days:

3/4 mile/day * 5 days = 15/4 miles

We can simplify this fraction to be:

15/4 = 3 3/4

The whole number portion of this result is 3, and the fractional portion is 3/4. Therefore, the total number of miles Karime walks is between 3 and 4.

In other words, the two whole numbers between which the total number of miles Karime walks are 3 and 4.

Total number of miles Karime walks altogether is,

⇒ 5 miles

We have to given that,

Karime walks 3/4 of a mile each day for 5 days.

Hence, To find number of miles Karime walks altogether, we can multiply 3/4 by 5.

So, We get;

Total number of miles Karime walks altogether is,

⇒ 3/4 x 5

⇒ 15 / 4

⇒ 3.75

⇒ 4 miles

Because 3.75 is nearest to 4.
