Answer:

12 is the best estimate

Answer:

option A.

Step-by-step explanation:

We have to find the circumference of the given circle with radius 2 units.

Since formula to calculate circumference of a circle is = 2πr

Where r = radius of the circle.

Circumference = 2 × (3.14) × (2)

                        =  4 × 3.14

                        = 12.56

So approximate value will be option A.

Answer:

a. _ √20 , about 4.472136

b - (-3, 8)

c- Slope of 2

Step-by-step explanation:

Calculator

Answer:

a. [tex]AB=2\sqrt{5}[/tex]

b. [tex](-3,8)[/tex]

c. [tex]2[/tex]

Step-by-step explanation:

You have the points:

A(-2,10)

where i will call: [tex]x_{1}=-2[/tex] and [tex]y_{1}=10[/tex]

B(-4,6)

where i will call: [tex]x_{2}=-4[/tex] and [tex]y_{2}=6[/tex]

for our calculations we are going to need the distance in x between the points ([tex]\Delta x[/tex] )and the distance in y between the points ([tex]\Delta y[/tex]):

[tex]\Delta x =|x_{2}-x_{1}|=|-4-(-2)|=|-4+2|=|-2|=2\\\Delta y =|y_{2}-y_{1}|=|6-10|=|-4|=4[/tex]

a. To find AB (the distance between point A and point B) you need The Pythagorean Theorem:

[tex](AB)^2=(\Delta x)^2+(\Delta y)^2\\(AB)^2=(2)^2+(4)^2\\(AB)^2=4+16\\\\AB=\sqrt{20}\\ AB=2\sqrt{5}[/tex]

b. to find the coordinates of the midpoint we average the x-coordinates and the y coordinates

[tex]x_{mid}=\frac{x_{1}+x_{2}}{2} =\frac{-2-4}{2}=\frac{-6}{2} =-3\\y_{mid}=\frac{y_{1}+y_{2}}{2} =\frac{10+6}{2}=\frac{16}{2} =8\\[/tex]

so the midpoint [tex](x_{mid},y_{mid})[/tex] is at: [tex](-3,8)[/tex]

c. For the slope we use the slope formula:

[tex]slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{6-10}{-4-(-2)}=\frac{-4}{-2}=2[/tex]

The slope is equal to 2.

Answer:

Option C is correct.

Step-by-step explanation:

[tex]\theta=\frac{5\pi }{6}[/tex]

We need to find reference angle and signs of sinФ, cosФ and tanФ

We know that [tex]\theta=\frac{5\pi }{6}radians[/tex] is equal to 150°

and 150° is in 2nd quadrant.

So, Ф is in 2nd quadrant.

And In 2nd quadrant sine is positive, while cos and tan are negative

The reference angle Ф' is found by: π - Ф

=> Ф = 5π/6

so, Reference angle Ф' = π - 5π/6

Ф' = 6π - 5π/6

Ф' = π/6

So, Option C Θ' = pi over 6; sine is positive, cosine and tangent are negative is correct.

Answer

The answer after you divide one number by another

dividend ÷ divisor = quotient

Example: in 12 ÷ 3 = 4, 4 is the quotient

Answer:

x = 9

Step-by-step explanation:

When 2 chords intersect inside a circle then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

2 × x = 3 × 6, that is

2x = 18 ( divide both sides by 2 )

x = 9

Answer:

The correct option is C

Step-by-step explanation:

x2 - 12x + 36

The coefficient of 1st term will be multiplied by the constant:

1*36 = 36

Now find two numbers whose product is 36 and whose addition is 12.

6*6 = 36

6+6 =12

Now break the middle term:

x^2-6x-6x+36 = 0

Now group the terms:

(x^2-6x) - (6x-36) = 0

Now take common of each group:

x(x-6)-6(x-6) = 0

(x-6) (x-6) =0

(x-6)=0    ,  (x-6) =0

x-6=0       , x-6=0

x=0+6      , x=0+6

x=6        ,   x=6

Thus the correct option is C. x=6 only....

Answer:

4.   2x^2 - 2x.

Step-by-step explanation:

Adding the 2 functions:

Area of the 2 triangles = x^2 + x + x^2 - 3x

= .2x^2 - 2x

Answer:

OPTION 4

Step-by-step explanation:

Let be f(x) the function that represents the area of Triangle A:

[tex]f(x)=x^2 + x[/tex]

Let be g(x) the function that represents the area of Triangle B:

[tex]g(x)=x^2 - 3x[/tex]

Then, you need to add the area of Triangle A and the area of Triangle B in order to find the sum of the areas (Let be h(x) the function that represents the sum of the the areas of triangles A and B):

Therefore, this is:

[tex]h(x)=(x^2 + x)+(x^2 - 3x)=x^2 + x+x^2 - 3x=2x^2-2x[/tex]

You can notice that this matches with the option 4.

Answer:

5.2

Step-by-step explanation:

Since you have a linear function, asking for derivative is equivalent to asking for the slope.

The slope of y=5.2x+2.3 is 5.2 so the derivative is 5.2 .

However, if you really want to use the definition of derivative, you may.

That is, [tex]\lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}[/tex].

We know [tex]f(x)=5.2x+2.3[/tex] so [tex]f(x+h)=5.2(x+h)+2.3[/tex].  All I did was replace any x in the 5.2x+2.3 with (x+h) to obtain f(x+h).

Let's plug it into our definition:

[tex]\lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}[/tex]

[tex]\lim_{h \rightarrow 0} \frac{[5.2(x+h)+2.3]-[5.2x+2.3]}{h}[/tex]

Now we need to do some distributing.  I see I need this distributive property both for the 5.2(x+h) and the -[5.2x+2.3].

[tex]\lim_{h \rightarrow 0} \frac{5.2x+5.2h+2.3-5.2x-2.3}{h}[/tex]

There are some like terms to combine in the numerator.  The cool thing is they are opposites and when you add opposites you get 0.

[tex]\lim_{h \rightarrow 0} \frac{5.2h}{h}[/tex]

There is a common factor in the numerator and denominator. h/h=1.

[tex]\lim_{h \rightarrow 0}5.2[/tex]

5.2

[tex]f(x)=5.2x+2.3\\f'(x)=5.2[/tex]

The value of sin n depends on the angle n and represents the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle.

The value of sin n depends on the angle n. In mathematics, sine is a trigonometric function that represents the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle. It is a periodic function that oscillates between -1 and 1 as the angle increases or decreases.

For example, if n is 0 degrees, then sin n is 0. If n is 90 degrees, then sin n is 1. If n is 180 degrees, then sin n is 0 again. The values of sin n for angles in between can be determined using a calculator or trigonometric tables.

It's important to note that in mathematics, the angle n is typically measured in radians rather than degrees. In radians, a full circle is equal to 2π, so an angle of 360 degrees is equal to 2π radians.

The answer is 675 units²

The surface area of the rectangular pyramid is 675 units².

The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.

We have to find the surface area of the rectangular pyramid.

So, to find the surface we need to find SA of each face

= (15 x 15) + (15 x 15)/2 x 4

= 225 + 225 x 2

= 225 + 450

= 675 units²

Answer:B, C, D, E.

Step-by-step explanation:

The third side of a triangle with two sides measuring 10 and 14 units must be greater than 4 and less than 24 units. This is determined using the Triangle Inequality Theorem.

The possible values for the third side of a triangle with sides of lengths 10 and 14 can be found using the Triangle Inequality Theorem.

Add the two given side lengths: 10 + 14 = 24.

To find the range of possible values for the third side, subtract the two given side lengths from the total: 24 - 10 = 14, and 24 - 14 = 10.

Therefore, the third side of the triangle must have a length greater than 4 but less than 24.

Answer:

D

Step-by-step explanation:

It crosses the y-axis at y=1 so the y-intercept is b=1.

The slope is count straight up from (-5,-2) to you are on the same horizontal level as (5,4).  The rise is 6

Once you get the same horizontal level as (5,4), you will count straight over to you get to (5,4). The run is 10.

Slope=rise/run=6/10=3/5.

Or you could find slope by using the slope formula.  I like to line up two pairs of points and subtract then put 2nd difference over first difference. Like so,

  (5,4)

-(-5,-2)

----------

 10   6

So the slope is 6/10 or 3/5 after reducing.

Slope-intercept form of a line is y=mx+b

Plug in m=3/5 and b=1

y=3/5 x +1

So the answer is D.

To solve the student's question, we calculated the time period from the initial amount and interest rate, then used that to determine the amount that Rs 600 would become at an 11% interest rate over the same period, which is Rs 930.

The essence of the question revolves around the concept of calculating the future amount of money based on the principal, the rate of interest, and the time for which the money is lent or invested. In the given scenario, we have a principal of Rs 500 which, at a 9% simple interest rate, amounts to Rs 725 over a certain period.

To find the equivalent amount for Rs 600 at an 11% interest rate over the same period, we need to first understand the amount of interest accrued in the first situation and use its proportion to calculate the second.

The formula for simple interest is Interest = Principal × rate × time.

First, let's calculate the interest earned on the initial Rs 500:

Now, we can calculate the time period using the simple interest formula:

Knowing the time period, we can find the amount that Rs 600 would amount to at an 11% interest rate over the same period:

So, Rs 600 will amount to Rs 930 at an 11% simple interest rate over the same time period of 5 years.

Answer: The total cost would be 37.95

Step-by-step explanation:

The total cost for the night, including a 15% tip on a $33 meal, is $37.95.

To calculate the total cost for the night, we need to add the meal cost and the tip. For a $33 meal, a 15% tip would be calculated using the formula tip = meal cost x tip percentage/ 100. In this case, tip = $33 x 15/100= $4.95. Therefore, the total cost for the night (meal cost + tip) would be $33 + $4.95 = $37.95.

Answer as a fraction: 4/15

Answer as a decimal: 0.267

The decimal version is approximate rounded to three decimal places.

=============================================================

Explanation:

6 apples, 4 peaches

6+4 = 10 pieces of fruit total

The probability of picking an apple is 6/10 = 3/5

After you pick and eat the apple, there are 10-1 = 9 pieces of fruit left. Also, the probability of picking a peach is 4/9, as there are 4 peaches out of 9 fruit left over.

Multiply out 3/5 and 4/9 to get (3/5)*(4/9) = (3*4)/(5*9) = 12/45 = 4/15

Using a calculator, 4/15 = 0.267 approximately.

Answer:

Fraction: [tex]\frac{4}{15}[/tex]

Decimal: [tex]0.2667[/tex]

Percent: 26.67%

Step-by-step explanation:

If the basket contains six apples and four peaches then the Total amount of fruit in the basket is (6+4) 10 pieces of fruit.

You reach in and randomly pick out an apple. Since there are only 4 apples, the probability of this happening was [tex]\frac{4}{10}[/tex] , and now there are only 9 pieces of fruit in the basket.

Now you reach in and randomly pick out a peach. Since there are 6 peaches, the probability of this happening is [tex]\frac{6}{9}[/tex]. Now we can find the probability of both of these things happening one after another by multiplying both probabilities together

[tex]\frac{4}{10} * \frac{6}{9}  = \frac{24}{90}[/tex]

[tex]\frac{24}{90} = \frac{4}{15}[/tex] ...... simplified

So we can see that the probability of you picking out an apple and a peach in sequence is [tex]\frac{4}{15}[/tex] or [tex]0.2667[/tex]

Step-by-step explanation:

no it is not because if 3 maps on 2, then it cannot map on -2 at the same time

A relation is considered a function if each input has only one output. The given set contains the input '3' with two different outputs '2' and '-2', therefore, it is not a function.

In mathematics, a relationship is considered a function if for every input there is only one output. In other words, no two pairs should have the same first element yet different second elements.

If we look at the set of ordered pairs provided, we have {(3, 2), (3, -2), (1, -4), (-1, 2)}. We can see that the input '3' corresponds to both '2' and '-2'. Since there are two outputs for the same input, we can determine that this relation is not a function.
