Tomic and Brooke make a game of shooting free throws. Each basket is worth 212 points. Each miss is worth −34 points. Out of 30 free throws, they make 16 baskets. What is the correct number of points that Tomic and Brooke scored?

The radius of Convergence  for the function [tex]\frac{\[(-1)^{n} \; x^{n} }{\sqrt[3]{n} }[/tex]  is 1.

The radius of the largest disk at the center of the series in which the series converges.

Perform the ratio test for absolute convergence, which says

if    [tex]\lim_{n \to \infty} \frac{a_{n}}{a_{n+1}}[/tex]   =L

Then,

1) if L<1, the series is absolutely convergent

2) If L>1, the series is divergent

3) If L= 1, apply a different test.

Now, Applying test

[tex]a_{n+1}[/tex] =[tex]\frac{(-1)^{{n+1} } \; x^{n+1}}{\sqrt[3]{n+1} }[/tex]

So,

[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_{n}}[/tex]  = [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}/\sqrt[3]{n+1} }{ (-1)^{n} \; x^{n} /\sqrt[3]{n} } |[/tex]

                     = [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}\sqrt[3]{n}}{ (-1)^{n} \; x^{n} \sqrt[3]{n+1} } |[/tex]

                     = [tex]\lim_{n \to \infty}|\frac{ (-1) \; x^{n}\sqrt[3]{n}}{ \sqrt[3]{n+1} } |[/tex]

                    = [tex]\lim_{n \to \infty}\sqrt[3]{\frac{1}{1+\frac{1}{n}} } } |x|[/tex]

Applying the limit n→∞,

= 1 x |x|

= |x|

By ratio test, the given series will be convergent if |x|< 1.

So, the radius of Convergence = 1

5 - 2 1/4 = 2 3/4

Answer:

4 units

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

given A = 14 and h = 7 , then

[tex]\frac{1}{2}[/tex] × 7b = 14 ( multiply both sides by 2 to clear the fraction )

7b = 28 ( divide both sides by 7 )

b = 4 units

Answer:

85% of 200 = 170

Step-by-step explanation:

Method

Let the number = x

60/100 * x = 120

0.6 x = 120                  Divide by 0.6

0.6x/0.6 = 120/0.6    

x = 200

25% x = 50                  Convert 25% to a fraction

25/100 x = 50

0.25x = 50                  Divide by 0.25

0.25x/0.25 = 50/0.25

x = 200

85% 200 = x               Change 85% to a fraction

85/100 * 200 = x        Multiply 85 and 200 together

17000 /100 = x          Divide by 100

170 = x

Answer

85% of 200 = 170

A=72CM^2

Step-by-step explanation:

The answer is 72cm^2 because the area of a triangle is h x b divided by two because the triangle is half of a square, since the square is side times side, the answer is 12x12 divided by two, wich is 144/2. The final answer is 72

Answer:

72

Step-by-step explanation:

area of a triangle = 1/2 × base length × height

base length = 12 and height = 12

so area = 1/2 × 12 × 12

==> multiply 12 by 12

area = 1/2 × 144

==> divide 144 by 2

Answer:

Vol_prism = 48 (all answers should have the units cm^3)

Vol_pyramid = 25

Vol_cyl = 37.68

Vol_cone = 12.56

Vol_sphere = 113.04

Step-by-step explanation:

This was a very compact problem (5 problems!) You read the chart top to bottom and each column is a different problem.

Vol of a prism:

V = l×w×h = 4×4×3

= 48 cm^3

Vol of a pyramid:

V = 1/3Base•h

= 1/3 (5×5)•3

= 25 cm^3

Vol of a cylinder:

V = pi•r^2•h

= pi•2^2•3

= pi•4•3

= 12pi = 12(3.14)

= 37.68 cm^3

Vol of cone:

= 1/3pi•r^2•h

= 1/3pi•2^2•3

= 4pi = 4(3.14)

= 12.56 cm^3

Vol of a sphere:

V = 4/3pi•r^3

= 4/3 pi•3^3

= 4/3 pi•27

= 36pi = 36(3.14)

= 113.04 cm^3

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

Explanation:

The figure is a polygon because it's composed of straight lines only, and we have a closed loop (or enclosed area).

This is a pentagon since it has 5 sides

The pentagon is concave because of the angle kicked in up top that caves in, so to speak. This interior angle exceeds 180 degrees and is known as a reflex angle.

Here's another way to determine the figure is concave: It's possible to pick two points inside the polygon such that the segment formed between them crosses outside the boundaries. See the diagram below.

Answer:

  101°

Step-by-step explanation:

The angles BEA and BED are a linear pair. They total 180°. (They are supplementary.)

__

  ∠BEA +∠BED = 180° . . . angles of a linear pair are supplementary

  79° +∠BED = 180° . . . . use the given angle value

  ∠BED = 101° . . . . . . . . . subtract 79°

The expression that represents the height of the prism is 2850/b where b is the base area

The given parameter is:

Volume = 2850

Let the height of the prism be h, and the base area be b.

The volume is calculated using:

V = bh

Make h the subject

h = V/b

Substitute V = 2850

h = 2850/b

Hence, the expression that represents the height of the prism is 2850/b

Answer:

14 mm

Step-by-step explanation:

Just as the little side is 1/4 of the larger side , so is the perimeter

1/4 * 56 = 14 mm

Step-by-step explanation:

2 things to remember :

1. the sum of all angles in a triangle is always 180°.

2. the sum of all angles around a single point on one side of a line is also 180° (because the line can be seen as the diameter of a circle, the point as its center, and so every side of the line is a half-circle = 180°).

so, the third, unnamed angle in the triangle is the supplementary angle to 142° (that means they complete each other to full 180°).

it is therefore

180 - 142 = 38°

and then, inside the triangle

180 = 66 + x + 38 = 104 + x

x = 76°

The volume of the Apple iPad Mini 2 is 12.561 in³.

The new volume of the  Pear-Apple is  24.53 in³.

The new volume of the  Pear-Apple is 5.3in³.

The scale factor to have a volume that is half that of the iPad Mini is 0.79.

The scale factor to have a volume that is double that of the iPad Mini is 1.26

Volume = length x width x height

7.9 x 5.30 x 0.30 = 12.561 in³

Dimensions after the 1.25 scale factor is applied: (1.25 x 7.9) x (1.25 x 5.30) x (1.25 x 0.3)

= 9.875 x 6.625 x0.375 = 24.53 in³

Dimensions after the 0.75 scale factor is applied: (0.75 x 7.9) x (0.75 x 5.30) x (0.75 x 0.3)

= 5.925 x 3.975 x 0.225 = 5.3in³

Scale factor to have a volume that is double that of the iPad Mini : [tex]2^{1/3}[/tex] = 1.26

Step-by-step explanation:

Answer:

20 + 6n > 75(the sign has an underline)

To determine how many miles Kayla needs to hike each week for the next 6 weeks to reach her goal of at least 75 miles, we can subtract the miles she has already hiked from her target goal and divide it by the number of weeks remaining.

Target goal - Miles already hiked = Miles remaining

75 miles - 20 miles = 55 miles remaining

Now, we divide the remaining miles by the number of weeks:

55 miles / 6 weeks = 9.17 miles per week (approximately)

Therefore, Kayla needs to hike approximately 9.17 miles each week for the next 6 weeks in order to reach her goal of at least 75 miles.
