Quadratic equations are equations that has a leading degree of 2. The solution to the given quadratic equation are 1/3 and 2

Quadratic equation are equation that has a leading degree of 2. Given the quadratic equation as shown:

3x^2=7x+2

Equate to zero to have:

3x² - 7x + 2 = 0

Factorize

3x² - 6x - x +2 = 0

3x(x-2) - 1(x- 2) = 0

Group

(3x-1)(x-2) = 0

3x - 1 = 0 and x - 2 = 0

Determine the values of x

Answer:

D

Step-by-step explanation:

The equation we'd use for this problem is y=a(1-b)^x (exponential decrease)

a is the initial amount, the number in the parentheses is the amount it decreases by, and x is time.

The initial amount is 8,500 since that is what we start with after 0 years. By looking at the chart we can see that the number decreases over time by a constant rate of .5, so that is the number in the parentheses. You then end the equation with ^t since t would be time in years

The location of Café 103 is (4.5, 4)

The given parameters are

From the question, we understand that:

Café 103 is collinear with and halfway between the Metrics School and the Angles Lab.

This means that Café 103 is at the midpoint

So, we have:

Café 103 = 0.5 * (x1 + x2, y1 + y2)

This gives

Café 103 = 0.5 * (2+ 7, 6 + 2)

Evaluate

Café 103 = (4.5, 4)

Hence, the location of Café 103 is (4.5, 4)

Step-by-step explanation:

Answer:

15.9p-13

Step-by-step explanation:

i had this question and got it right

Step-by-step explanation:

please make sure that fractions are still in the problem text after scanning it.

because they are missing here, and I have to guess around.

Basically the problem is

x + 1/a × x = 15

that means

ax + x = 15a

(a+1)x = 15a

x = 15a/(a+1)

for a = 2 (so, 1/2 x is added to x), we get

x = 15×2/3 = 30/3 = 10

for a = 4 (1/4 of x is added to x), we get

x = 15×4/5 = 60/5 = 12

these are also the first 2 answer options. so, please pick the one that fits the complete problem definition.

the 3rd and 4th answer options are nonsense anyway, as when you add something greater than 0 to x and get 15, then the initial x cannot be already 15 or even bigger.

Answer: 182

Step-by-step explanation:

The solution set of the example inequality, 2•x + 3 ≤ -3, is the option;

A possible inequality that can be used to get one of the options, (the inequality is not included in the question) is as follows;

Solving the above inequality, we have;

2•x + 3 ≤ -3

2•x ≤ -3 - 3 = -6

2•x ≤ -6

Therefore;

x ≤ -6 ÷ 2 = -3

x ≤ -3

Which gives;

-∞ < x ≤ -3 in interval notation is (-∞, -3]

The solution set of the inequality, 2•x + 3 ≤ -3, is therefore the option;

x=10.5

The value of x from the given rectangle is 10.5 units.

The opposite sides of a rectangle are 3(x+4) and 5x-9.

A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.

Now, the opposite sides of a rectangle are congruent

So, 3(x+4) = 5x-9

⇒ 3x+12=5x-9

⇒ 5x-3x=12+9

⇒ 2x=21

⇒ x=10.5 units

Therefore, the value of x from the given rectangle is 10.5 units.

There is a lower limit but no upper limit for a random variable that follows the exponential probability distribution.

We know that, an exponential distribution is a type of continuous distributions.

This probability distribution times the occurrence of events.

In exponential probability distribution, events happen continuously and independently at a constant average rate.

The continuous random variable, say X is said to have an exponential distribution, if it has the following probability density function:

[tex]f_X(x)=\left \{ {{\lambda e^{-\lambda x~~~x > 0}} \atop {0~~~~~~~x\leq 0}} \right.[/tex]

The exponential distribution is memoryless.

We know that, for exponential the lower limit is 0, but the upper limit is infinity, meaning there is no upper limit.

Therefore, There is a lower limit but no upper limit for a random variable that follows the exponential probability distribution.

Given data

The two triangle that has the values are attached:

The value of x

( 2x + 6 ) mm = 36 mm

2x mm = ( 36 - 6 ) mm

2x mm = 30 mm

x = 30 / 2 mm

x = 15 mm

The value of y

( 6y ) mm = 36 mm

y = 36 / 6 mm

y = 6 mm

The value of z

( 3z + 39 ) mm = 51 mm

3z mm = ( 51 - 39 ) mm

3z mm = 12 mm

In 25.76 seconds we will fill the total volume of the cylinder.

The total volume of the cylinder is given by the equation:

V = pi*R^2*H

Where pi = 3.14, R is the radius and H is the height.

Here we know that the diameter is 6 inches, then the radius is:

R= 6in/2 = 3in

And the height is 8 inches, then the volume is:

V = 3.14*(3in)^2*8in = 226.08 in^3

We already have 20 cubic inches of water there, so what we need to fill is:

226.08 in^3 - 20in^3 = 206.08in^3

If we fill it at a rate of 8in^3/s, the time in which we will completely fill the cylinder is:

T = 206.08in^3/8in^3/s = 25.76s

In 25.76 seconds we will fill the total volume of the cylinder.

Answer:

93

Step-by-step explanation:

143 —————>233 = 90

233 —————>237 = 3

90 + 3 = 93

The number of the whole numbers lying between 237 and 143 will be 94.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Zero, a consistently positive number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive values are negative in value. The set of integers is frequently represented in mathematical notation by the big bold letters Z.

The number of the whole numbers lying between 237 and 143 will be given by the subtraction of the numbers from 237 to 143. Then we have

⇒ 237 - 143

⇒ 94

The number of the whole numbers lying between 237 and 143 will be 94.
