Answer: Option G

[tex]a_6 = -2048[/tex]

Step-by-step explanation:

The geometric series have the following form:

[tex]a_n = a_1 (r) ^ {n-1}[/tex]

Where [tex]a_1[/tex] is the first term of the sequence and r is the common radius.

In this case we know that

[tex]a_1 = -2\\\\r = 4[/tex]

So:

[tex]a_n = -2(4) ^ {n-1}[/tex]

To find the sixth term [tex]a_6[/tex], substitute [tex]n = 6[/tex] in the equation.

[tex]a_6 = -2 (4) ^ {6-1}\\\\a_6 = -2 (4) ^ 5\\\\a_6 = -2048[/tex]

Answer:

(x + 2)² + (y - 2)² = 64

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 2, 2), thus

(x + 2)² + (y - 2)² = r²

Given C = 2πr = 16π ( divide both sides by 2π )

r = [tex]\frac{16\pi }{2\pi }[/tex] = 8

Hence

(x + 2)² + (y - 2)² = 64 ← equation of circle

To find the equation of the circle with center at (-2,2) and a circumference of 16π, first calculate the radius r=8 from the circumference, then use the formula (x+2² + (y-2)² = 64.

The question asks for the equation of a circle with a given center and circumference. The center of the circle is located at (-2,2), and the circumference is 16π. First, we calculate the radius of the circle using the formula for circumference, C = 2πr, where C is the circumference and r is the radius. Since C = 16π, we can solve for r to find that the radius r = 8 units.

Next, we use the standard equation of a circle, which is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is its radius. Therefore, substituting h = -2, k = 2, and r = 8 into the equation, we get (x + 2)² + (y - 2)² = 64, which is the equation that represents the circle with the given center and circumference.

Answer:

9.2 ft

Step-by-step explanation:

The length of the ladder is 15 ft

The ladder makes an angle of 52° with the ground

The distance (x) from the base of the house to the foot of the ladder is given by;

[tex]\frac{x}{15}[/tex] = cos 52°

x = 15 × cos 52° = 9.23492213 ft

Which equals to 9.2 ft (rounded off to tenth of a foot)

The distance between the base of the building and the bottom of the ladder is 11.72 feet.

It is given that

Length of the ladder = 15 feet

The angle of inclination = 52°

Let us say the distance between the base of the building and the bottom of the ladder is x.

The tangent of an angle is the ratio of the opposite side(to that angle) to the base of the triangle.

Tan 52° = length of the ladder / distance between base of building and bottom of the ladder.

Tan 52 = 15/x

x= 15/Tan 52

x = 11.72 feet.

Therefore, The distance between the base of the building and the bottom of the ladder is 11.72 feet.

Answer: -3

Step-by-step explanation:8-5=3 take the negative so it’s -3

Answer:

25%

Step-by-step explanation:

The chance of flipping heads or tails is 50%.

We have to flip heads or tails 3 times.

To make this easier, I will convert 50% to 1/2 for the time being.

Since the chance of getting heads or tails is 1/2 and there are 3 flips, multiply 1/2 to the power of 3, which is 1/8

1/8 is the probability of getting this outcome.

"The interquartile range increases"

The value of the (RIC) will increase from 4 to 5.75, that is, 44%

Step-by-step explanation:

The range is defined as the difference between the maximum and minimum value of a series of data. Xmax - Xmin

The interleaving range (RIC) is a measure of dispersion that measures the central range of 50% of the data.

Therefore, if a low value is included, such as five, the variance of the data would be greater and, consequently, the value of the (RIC) will increase from 4 to 5.75, that is, 44%

The expression 36a^2 - 49b^2 can be factored into the product of two binomials by applying the difference of squares formula. The factored form of the expression is (6a - 7b)(6a + 7b).

The expression 36a^2 - 49b^2 is a difference of squares. A difference of squares is a special type of binomial that can be factored into the product of two binomials.

In general, if you have an expression of the form x^2 - y^2, this is equal to (x - y)(x + y).

In the case of the expression 36a^2 - 49b^2, 36a^2 is the square of 6a, and 49b^2 is the square of 7b. Therefore, the expression 36a^2 - 49b^2 can be factored into (6a - 7b)(6a + 7b).

Final answer:

The expression 36a² - 49b² is factored as (6a + 7b)(6a - 7b) using the difference of squares identity a² - b² = (a + b)(a - b).

Explanation:

The expression 36a² - 49b² is a difference of squares which can be factored using the identity a² - b² = (a + b)(a - b). In this case, the expression can be written as (6a)² - (7b)². This resembles the identity where a is 6a and b is 7b. Applying the identity, we get:

(6a + 7b)(6a - 7b)

This is the factored form of the given expression. To understand why this works, we recognize that squaring a number and then subtracting the square of another number creates two terms, one positive and one negative, whose products with themselves give us the original expression. The factored form thus represents two binomials that reflect the sum and the difference of the square roots of the original terms, respectively.

Answer: Option C

The equation is:

[tex](x+8)^2 +(y+3)^2=9[/tex]

Step-by-step explanation:

First we must calculate the midpoint between the two given points.

Then the midpoint will be the radius of the circumference

The midpoint between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is:

[tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

In this case the points are:

(-5 -3) and (-11 -3)

The the center is:

[tex](\frac{-5-11}{2}, \frac{-3-3}{2})[/tex]

[tex](-8,\ -3)[/tex]

Then the equation is:

[tex](x+8)^2 +(y+3)^2=r^2[/tex]

To find r we substitute one of the points in the equation and solve for r

[tex](-5+8)^2 +(-3+3)^2=r^2[/tex]

[tex](3)^2 +0=r^2[/tex]

[tex]r^2 =3^2[/tex]

[tex]r =3[/tex]

Finally the equation is:

[tex](x+8)^2 +(y+3)^2=9[/tex]

Answer:

Option C

Step-by-step explanation:

The standard form of equation of circle is:

(x-h)^2+ (y-k)^2=r^2

As we only know two points on the circle which are the ends of diameter.

As we know

Radius=Diameter/2

We have to find the length of diameter using the distance formula first to calculate radius. So,

Diameter= √((-11-(+5))^2+(-3-(-3)^2 )

= √((-11+5)^2+(-3+3)^2 )

=√((-6)^2+(0)^2 )

= √36

=6

Now,  

Radius=6/2

=3

As the diameter passes through centre, so the mid-point of diameter will be centre of the circle:

Mid-point=((x_1+x_2)/2,(y_1+y_2)/2)

=((-5-11)/2,(-3-3)/2)

=((-16)/2,(-6)/2)

=(-8,-3)

Putting the values of radius and centre in standard form

(x-h)^2+ (y-k)^2=r^2

(x-(-8))^2+ (y-(-3))^2=3^2

(x+8)^2+ (y+3)^2=9

So the correct answer is option C ..

Answer:

The data set "types of fruit at the grocery store" is qualitative.

The correct answer is B.

The correct option is a. quantitative, discrete.

The data set "types of fruit at the grocery store" is quantitative because it involves counting the number of different types of fruit, which is a numerical value. Furthermore, it is discrete because the count of fruit types will result in whole numbers, with no fractional or continuous values between them. For example, one cannot have 3.5 types of fruit; it must be a whole number such as 3 or 4. Therefore, the data is not qualitative as it is not about the characteristics or attributes of the fruit but rather the count of different categories of fruit. It is also not continuous as the number of fruit types cannot vary smoothly and must be counted in whole units.

For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:

[tex]Sin (45) = \frac {leg} {h}[/tex]

Where h is the hypotenuse.

[tex]\frac {\sqrt {2}} {2} = \frac {leg} {h}[/tex]

We cleared h:

[tex]h = \frac {2leg} {\sqrt {2}}[/tex]

We rationalize:

[tex]h = \frac {2leg} {\sqrt {2}} * \frac {\sqrt {2}} {\sqrt {2}}\\h = \frac {2 \sqrt {2} * leg} {2}\\h = \sqrt {2} * leg[/tex]

Step-by-step explanation:

Let's say R is the initial radius of the sphere, and r is the radius at time t.

The volume of the sphere at time t is:

V = 4/3 π r³

Taking derivative with respect to radius:

dV/dr = 4π r²

This is a maximum when r is a maximum, which is when r = R.

(dV/dr)max = 4π R²

This is 4 times the sphere's initial great circle area, but not the great circle circumference.  The problem statement contains an error.
