Answer:

21.99115 ≈ 22 cm

Step-by-step explanation:

1) So basically in the problem, they give you 7 cm as the diameter.

2) The circumference formula is C = 2πr (if they give you a radius) or C = πd (In this case, this would be the formula to use.)

3) Plug in; C = π(7) = 21.99114858 ≈ 22 cm

Step-by-step explanation:

The two positive numbers are 5 , 5.

Given:

Product of two positive numbers = 25

sum of these number is minimum.

Let a and b be the two positive numbers.

a*b = 25

b = 25/a

sum s = a+b

= a + 25/a

apply derivation on both sides.

ds/da = 1 - 25/\(a^{2}\)= 0.

1 = 25/\(a^{2}\)

a = \(\sqrt{25}\)

a = 5 , -5

since given are positive numbers so 5 is considered.

b = 25/5

b = 5

Therefore the two positive numbers are 5 , 5.

The given limit can be expressed as the definite integral of the function (5x^2 - 11x + 12) over the interval [0, 5]. Therefore, the answer is option D: ∫ 0^5 (5x^2 - 11x + 12) dx.

To express the given limit as a definite integral, we observe that the sum in the limit can be represented as a Riemann sum.

Each term in the sum involves the function (5c^2 - 11c + 12) multiplied by Δx_k, where Δx_k represents the width of each subinterval.

As the limit of ∥P∥ approaches 0, the sum approaches the definite integral of the function (5x^2 - 11x + 12) over the interval [0, 5]. This can be represented as ∫ 0^5 (5x^2 - 11x + 12) dx.

Therefore, the answer is option D: ∫ 0^5 (5x^2 - 11x + 12) dx.

Answer:

Step-by-step explanation:

AD = BC = 8 ( opposite sides of a parallelogram are congruent )

DC = AB = 15 ( opposite sides of a parallelogram are congruent )

Consecutive angles in a parallelogram are supplementary , sum to 180° , so

∠ A + ∠ D  = 180° , that is

∠ A + 68° = 180° ( subtract 68° from both sides )

∠ A = 112°

the opposite angles of a parallelogram are congruent , then

∠ B = ∠ D = 68° , and

∠ C = ∠ A = 112°

Answer:

Step-by-step explanation:

Can you show me all other answer choices? I know obviously that A) isn't the right answer.

The equation of the line that is parallel to the given line and passes through the point (–2, 2) is: B. y = 1/5(x) + 12/5

In order to determine the equation of this line, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;

\(Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope\;,m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

By critically observing the graph of the line, we can logically deduce the following points:

Point (x, y) = (0, -3)

Point (x, y) = (-5, -4)

Substituting the given points into the formula, we have;

Slope = (-4 - (-3))/(-5 - 0)

Slope = (-4 + 3)/(-5)

Slope = -1/-5

Slope = 1/5

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

At point (-2, 2), we have:

y - 2 = 1/5(x - (-2))

y - 2 = 1/5(x + 2)

y - 2 = x/5 + 2/5

y = x/5 + 2/5 + 2

y = x/5 + 12/5

y = 1/5(x) + 12/5

Answer:

slope = -1/2

Step-by-step explanation:

we use point B and point A to find the slope

A(-2,1)    B(-4,2)

-2 = x1

1 = y1

-4 = x2

2 = y2

the formula for slope is: y/x = y1 - y2  /  x1 - x2 = 1 -2 / -2-(-4) = -1/2

The change in one variable related to the change in more than one other variable is measured using multiple regression analysis.

A statistical method known as multiple regression is used on datasets intended to show a link between a single response or dependent variable and a number of independent factors.

Even though linear regression is frequently employed, it can only be utilized with one independent variable and one dependent variable. Non-linear regression is not predicted by linear regression, which is also limited to the training dataset.

We employ multiple regression to account for the same restrictions. It focuses on removing one particular limitation, which is allowing for the analysis of multiple independent variables.

the new club sent out 50 coupons to existing members and 150 coupons to potential members to boost sales for next year's memberships.

How to solve the question?

Let x be the number of coupons sent to existing members. Then the number of coupons sent to potential members is 3x, as they provided 3 times as many coupons to potential members than to existing members.

According to the problem, the total number of coupons sent is 200. Therefore, we can write the following equation:

x + 3x = 200

Simplifying this equation, we get:

4x = 200

Dividing both sides by 4, we get:

x = 50

Therefore, the number of coupons sent to existing members is 50, and the number of coupons sent to potential members is 3 times as many, or 150.

In conclusion, the new club sent out 50 coupons to existing members and 150 coupons to potential members to boost sales for next year's memberships.

Answer:

Si llamamos a los ángulos α y β

α = 1/2 β - 30

como se trata de un triángulo rectángulo , el ángulo recto mide 90° , entonces los otros dos suman 90°

α + β = 90

( 1/2 β - 30 ) + β = 90

1/2 β + β = 90 + 30

1/2 β + 2/2 β = 120

3/2 β = 120

β = ( 120 ) ( 2 ) / 3

β = 240/3

β = 80°

calculamos α

α = ( 80 / 2 ) - 30

α = 40 - 30

α = 10°

We have proven that if a>b and c<0, then a/c < b/c as shown below

From the question, we are to prove the given expression.

To prove that if a>b and c<0, then a/c < b/c

We will choose some numbers to represent the letters a, b, and c that satisfy the given conditions

From the given information,

a > b

Let a = 16

and b = 8

Also, from the given information

c<0

Let c = -4

Now, evaluate a/c

a/c = 16/-4

a/c = -4

Evaluating b/c

b/c = 8/-4

b/c = -2

-4 < -2

Therefore,

a/c < b/c

Hence, we have proven that if a>b and c<0, then a/c < b/c
