Is the sequence geometric? If so, identify the common ratio.256, 64, 16, 4…a) yes, 4b) yes, 3/4c) yes, 1/4d) no

The probability of selecting an 8 is \(\frac{4}{52}\) since there are 4 total 8's available (8 of hearts/spades/diamonds/clubs) out of 52 cards. This simplifies to \(\frac{1}{13}\). The probability of selecting a face card is \(\frac{12}{52}\) since there are 4 Jacks, 4 Queens, and 4 Kings. This simplifies to \(\frac{3}{13}\).  1 - \(\frac{3}{13}\) = \(\frac{13}{13}\) - \(\frac{3}{13}\) =\(\frac{10}{13}\).

There are four suits (hearts, spades, diamonds, and clubs), each with 13 cards from Ace to King, in a conventional 52-card deck of playing cards. As a result, there are four of each potential card.

(A) The probability of selecting an 8 is  \(\frac{4}{52}\) since there are 4 total 8's available (8 of hearts/spades/diamonds/clubs) out of 52 cards. This simplifies to \(\frac{1}{13}\).

(B) The probability of selecting a face card is \(\frac{12}{52}\) since there are 4 Jacks, 4 Queens, and 4 Kings. This simplifies to \(\frac{3}{13}\).

(C) The probability of NOT selecting a face card is \(\frac{40}{52}\) since there are 4 of each card from Ace through 10 that are not face cards. This simplifies to 10/13. The solution to part B's question can be used as another way to approach this issue. If the probability of selecting a face card is 3/13, then the probability of NOT selecting a face card has to be 1 - \(\frac{3}{13}\) = \(\frac{13}{13}\) - \(\frac{3}{13}\) =\(\frac{10}{13}\). Recall that you must deduct from 1 since the probability of all conceivable outcomes must add up to 1, or 100%.

Therefore, the probability of selecting an 8 is \(\frac{4}{52}\) since there are 4 total 8's available (8 of hearts/spades/diamonds/clubs) out of 52 cards. This simplifies to \(\frac{1}{13}\). The probability of selecting a face card is \(\frac{12}{52}\) since there are 4 Jacks, 4 Queens, and 4 Kings. This simplifies to \(\frac{3}{13}\). the probability of NOT selecting a face card has to be 1 - \(\frac{3}{13}\) = \(\frac{13}{13}\) - \(\frac{3}{13}\) =\(\frac{10}{13}\).

BECAUSE ISOSCELES TRIANGLE IS A TRIANGLE WITH 2 SIDES EQUAL....

EQUILATERAL TRIANGLE HAS ALL SIDES AND ANGLES EQUAL, so equilateral triangle also has 2 sides equal

Answer:

no it is not can you look at your coments

Using implicit differentiation dy/dx = -(2x + y)/(x + 2y) and d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³.

Implicit differentiation is the process of differentiating an equation in which it is not easy or possible to express y explicitly in terms of x.

Given the equation x² + xy + y² = 5,

we can differentiate both sides with respect to x using the chain rule as follows:

2x + (x(dy/dx) + y) + 2y(dy/dx) = 0

Simplifying this equation yields:

(x + 2y)dy/dx = -(2x + y)

Hence, dy/dx = -(2x + y)/(x + 2y)

Next, we need to find d^2y/dx^2 by differentiating the expression for dy/dx obtained above with respect to x, using the quotient rule.

That is:

d/dx(dy/dx) = d/dx[-(2x + y)/(x + 2y)](x + 2y)d^2y/dx² - (2x + y)(d/dx(x + 2y))

= -(2x + y)(d/dx(x + 2y)) + (x + 2y)(d/dx(2x + y))

Simplifying this equation yields:

d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³

The length of the apothem of the regular pentagon shown is 5.2 meters

Represent the central angle of the regular pentagon using x

The value of the central angle of the regular pentagon is then calculated as:

x = 360/n

Where n represents the number of sides

i.e n = 5

So, we have:

x = 360/5

Evaluate the quotient

x = 72

Represents the apothem with y.

The apothem is then calculated as:

tan(x/2) = (Side length/2)/Apothem

This gives

tan(72/2) = (7.6/2)/y

Evaluate the quotient

tan(36) =3.8/y

Multiply both sides by y

y tan(36) = 3.8

Divide both sides by tan(36)

y = 3.8/tan(36)

Evaluate the quotient

y = 5.2

Hence, the length of the apothem of the regular pentagon shown is 5.2 meters

Answer:

x is 34.28 rounded to the nearest hundredth

Step-by-step explanation:

Since it is a right-angled triangle, using Pythagoras' rule; SOH/CAH/TOA

Since the known variables are: Opposite(19), Adjacent(x), and Theta(29°);

So, TOA would be used;

tan 29° = 19 / x (cross multiply) Making x the subject of the formula;

x = 19 / tan 29° = 34.276 = 34.28 rounded to the nearest hundredth

x = 34.28

Step-by-step explanation:

The mean of the data set is 82.77

If we want to find the mean, we would have to put it at the back of our minds that the mean is the same as the average. As such, we would have to take the sum of all the values that have been listed in the data set and divide by the total number of the data.

The first step is to arrange the data set orderly from smallest to largest;

70, 71,79, 82,88,85,87,91,92

We have nine values in the data set thus the mean is;

70+71+79+82+88+85+87+91+92/9= 745/9= 82.77

Hence the mean of the data set is 82.77

Step-by-step explanation:

Answer:

The trigonometric ratios are presented below:

\(\sin \theta = \frac{AC}{\sqrt{AC^{2} + BC^{2}}}\)

\(\cos \theta = \frac{BC}{\sqrt{AC^{2} + BC^{2}}}\)

\(\cot \theta = \frac{BC}{AC}\)

\(\sec \theta = \frac{\sqrt{AC^{2}+BC^{2}}}{BC}\)

\(\csc \theta = \frac{\sqrt{AC^{2}+BC^{2}}}{AC}\)

Step-by-step explanation:

From Trigonometry we know the following definitions for each trigonometric ratio:

Sine

\(\sin \theta = \frac{y}{h}\) (1)

Cosine

\(\cos \theta = \frac{x}{h}\) (2)

Tangent

\(\tan \theta = \frac{\sin \theta}{\cos \theta} = \frac{y}{x}\) (3)

Cotangent

\(\cot \theta = \frac{\cos \theta}{\sin \theta} = \frac{x}{y}\) (4)

Secant

\(\sec \theta = \frac{1}{\cos \theta} = \frac{h}{x}\) (5)

Cosecant

\(\csc \theta = \frac{1}{\sin \theta} = \frac{h}{y}\) (6)

Where:

\(x\) - Adjacent leg.

\(y\) - Opposite leg.

\(h\) - Hypotenuse.

The length of the hypotenuse is determined by the Pythagorean Theorem:

\(h = \sqrt{x^{2}+y^{2}}\)

If \(y = AC\) and \(x = BC\), then the trigonometric ratios are presented below:

\(\sin \theta = \frac{AC}{\sqrt{AC^{2} + BC^{2}}}\)

\(\cos \theta = \frac{BC}{\sqrt{AC^{2} + BC^{2}}}\)

\(\cot \theta = \frac{BC}{AC}\)

\(\sec \theta = \frac{\sqrt{AC^{2}+BC^{2}}}{BC}\)

\(\csc \theta = \frac{\sqrt{AC^{2}+BC^{2}}}{AC}\)

The number of cannonballs in illustration is 506.

Math Illustrations enables you to produce more useful geometry figures for your students in less time by fusing the constraint-based design of Geometry Expressions with simple-to-use sketching and graphing features.

The number of cannonballs in the first layer = 1² = 1

Number of cannonballs in the second layer = 2² = 4

Number of cannonballs in the third layer = 3² = 9

So, the generalized formula to count the balls is given as

= n(n + 1) (2n + 1)/ 6

Here, n= the total number of layers

Put n =11

11(11 + 1)(2(11) + 1) / 6

Answer:

15 ft

Step-by-step explanation:

Let the height of the wall be represented bad x

Applying the theorem of similarity, we would have the following equation:

\( \frac{x}{6} = \frac{9 + 6}{6} \)

\( \frac{x}{6} = \frac{15}{6} \)

\( \frac{x}{6} = \frac{5}{2} \)

Cross multiply

\( x*2 = 5*6 \)

2x = 30

Divide both sides by 2

x = 15

Thus, the height of the wall = 15 ft

The slope of g(t) as (-2,2) is given by

\(g'(t)=2t+6\)

\(g'(-2)=2(-2)+6=2\)

Since the normal is parallel to the tangent of f(t) at (1, 1/2),

The tangent line of f(t) has a slope of

\(\dfrac{d}{dx}f(t)=n+2mt=2\)

At point (1, 1/2), we know

\(f'(1)=n+2m=2\)

\(f(1)=2+n(1)+m(1)^2=2+n+m=\frac12\)
