which of the following functions represent the graph g(x) above

The value of angle k is 129⁰.

The value of angle b is 64.5⁰.

The value of angle b and angle k is calculated by applying the following principle of intersecting chord theorem.

k + 113 + 118 = 360 (sum of angles in a circle)

k + 231 = 360

k = 360 - 231

Answer:

Step-by-step explanation:

Answer:

(p + 2)(3b - 7)

Step-by-step explanation:

3b(p + 2) - 7(p + 2) ← factor out common factor (p + 2) from each term

= (p + 2)(3b - 7)

The function values are f(10) = 198 and g(-6) = 24/7; the range of h(x) is 3/5 < h(x) < 31/25 and the inverse function is p-1(x) = -(1 + 3x)/(5 + x)

Given that

f(x) = 2x^2 - 2

g(x) = 4x/(x - 1)

So, we have

f(10) = 2(10)^2 - 2 = 198

g(-6) = 4(-6)/(-6 - 1) = 24/7

Here, we have

h(x) = (7x - 4)/5x

Where

1 < x < 5

So, we have

h(1) = (7(1) - 4)/5(1) = 3/5

h(5) = (7(5) - 4)/5(5) = 31/25

So the range is 3/5 < h(x) < 31/25

Here, we have

P(x) = (5x - 1)/(3 - x)

So, we have

x = (5y - 1)/(3 - y)

This gives

3x - xy = 5y - 1

So, we have

y(5 + x) = -1 - 3x

This gives

y = -(1 + 3x)/(5 + x)

So, the inverse function is p-1(x) = -(1 + 3x)/(5 + x)

The probability that Bashir chooses a card that is either a face card or a spade is 11/26.

To find the probability that the card Bashir chooses is either a face card or a spade, we need to add the probabilities of the two events occurring and then subtract the probability of their intersection (choosing a face card that is also a spade).

First, we need to find the probability of choosing a face card. There are 12 face cards in a deck (4 jacks, 4 queens, and 4 kings), and a total of 52 cards, so the probability of choosing a face card is

P(F) = 12/52 = 3/13

Next, we need to find the probability of choosing a spade. There are 13 spades in a deck (from 2 to ace), and a total of 52 cards, so the probability of choosing a spade is

P(S) = 13/52 = 1/4

To find the probability of choosing either a face card or a spade, we can use the formula

P(F or S) = P(F) + P(S) - P(F and S)

We need to find the probability of choosing a face card that is also a spade (their intersection). There are only 3 face cards that are spades (jack of spades, queen of spades, king of spades), so the probability of choosing a face card that is also a spade is

P(F and S) = 3/52

Now we can plug in the values to get

P(F or S) = P(F) + P(S) - P(F and S)

P(F or S) = 3/13 + 1/4 - 3/52

P(F or S) = 12/52 + 13/52 - 3/52

P(F or S) = 22/52

P(F or S) = 11/26

Step-by-step explanation:

Answer:

    [tex]\textsf{Choice A } \quad y = \dfrac{5}{3}x + 1[/tex]

Step-by-step explanation:

Slope intercept form of a line equation is

y = mx + b

where

m = slope

b = y-intercept

A perpendicular line to y = mx + b will have a slope of -1/m

Let's first find the equation for line z in slope-intercept form
Slope m for a line  = (y2- y1)/(x2 - x1) where x1, y1 and x2, y2 are two points on the line

Slope of line z is
[tex]m = \dfrac { 2 - (-1) }{-2 - 3} = \dfrac{3}{-5} = - \dfrac{3}{5}[/tex]

So line z will have an equation of the form
[tex]y = -\dfrac{3}{5}x + b[/tex]

We know that a line perpendicular to this line will have a slope of
[tex]- \dfrac{1}{-\dfrac{3}{5}} = \dfrac{5}{3}[/tex]

So the equation of the perpendicular line is
[tex]y = \dfrac{5}{3}x + b[/tex]

Only one of the 4 choices, name choice A has this slope of 5/3

Therefore the correct answer choice is A

There is no need to compute b, the y intercept but if you wanted to, this is how you would do it:

The perpendicular line passes through (3, 6). This means when x = 3, y =6

Substitute these values of x, y into the equation for the perpendicular line and solve for b

[tex]y = \dfrac{5}{3}x + b\\\\\text{When x = 3, y = 6}:\\\\6 = \dfrac{5}{3} \cdot 3 + b\\\\6 = 5 + b\\\\b = 6 - 5 = 1\\\\\text{So, the equation of the perpendicular line is }\\y = \dfrac{5}{3}x + 1[/tex]

This corresponds to Choice A

The measure of arc CFE is 246⁰.

The measure of arc FED is 190⁰.

The value of the angle CFE is 57⁰.

The value of the angle DEF is 85⁰.

The value of the angles is calculated by applying intersecting chord theorem.

This theorem states that the angle at tangent is half of the arc angle of the two intersecting chords.

angle CFE = 180 - 123 (opposite angles of a cyclic quadrilateral)

angle CFE = 57

arc CDF = 2 x 57

arc CDF = 114

arc CFE = 360 - 114 = 246⁰

angle DEF = 180 - 95

angle DEF = 85

arc DCF = 2 x 85 = 170

arc FED = 360 - 170 = 190

The amount of dry ingredients used in the cake recipe is approximately 7 cups.

We have,

3 ½ cups of flour, 2 ⅔ cups of sugar, and 1 ¾ cups of cocoa.

Now, first convert all quantity in same unit.

3 ½ cups of flour

= 3 cups + 0.5 cups

= 3 cups and 8 ounces.

and, 2 ⅔ cups of sugar

= 2 cups + 0.67 cups,

= 2 cups and 10.72 ounces.

and, 1 ¾ cups of cocoa

=1 cup + 0.75 cups

= 1 cup and 12 ounces.

So, the total amount

= 3 cups and 8 ounces + 2 cups and 10.72 ounces + 1 cup and 12 ounces = 6 cups and 14.72 ounces

Step-by-step explanation:

a probability is airways the ratio

desired cases / totally possible cases

2 questions, each with a true or false answer option.

that gives us

2 × 2 = 4 answer options in total (the totally possible cases).

but only one of the four combinations is completely right.

so, the probability is

1/4

the 4 possibilities are

true true

false false

true false

false true

formally we can get to the result that way :

the first question has 2 options.

the probabilty to get it right is therefore

1/2

the same for the second question

1/2

but both have to be right for the desired result (question 1 AND question 2 have to be right), so, we need to combine both individual probabilities :

1/2 × 1/2 = 1/4

Note that the probability of both questions being right by guessing is 0.25 or 1/4.

P (both correct) = P(correct on Q1 ) x p(correct on Q2)
=   0.5 x 0.5
= 0.25 or 1/4

B. Similarly, the fish from region B weighs about 279 kg (614 x 0.453592), rounded to the nearest whole number.

The required graph has been attached below that represents the function f(x) = 5 cos (2x).

The graph of the function f(x) = 5 cos(2x) is a periodic function that oscillates between its maximum and minimum values as x changes.

Specifically, the function is a cosine function with amplitude 5 and period π, since the coefficient of x is 2 in the argument of the cosine function.

The graph of the function f(x) = 5 cos(2x) has a maximum value of 5 when cos(2x) = 1 (i.e., at 2x = 0 + 2πk, where k is an integer), and a minimum value of -5 when cos(2x) = -1 (i.e., at 2x = π + 2πk, where k is an integer).

The amount of paint needed to paint all the surfaces of the 11 poles is; 1260 ft².

It follows from the task content that the amount of paint required to paint all the surfaces of the 11 poles is required to be determined.

First, since the surface area of a cylindrical pole is; A = 2πr (r + h).

where height,h = 22 and radius, r = diameter / 2 = 1.6 / 2 = 0.8 feet.

Therefore, A = 2 × 3.14 × 0.8 (22 + 0.8)

A = 114.5472 ft²

Therefore, for all 11 poles; the total area is; 11 × 114.5472 = 1260 ft² to the nearest whole number.

Answer: The spinner is probably because 5 was spun approximately 200 times

Step-by-step explanation:

The Cartesian equation of the polar equation r = 4 sin(θ)cos(θ) is:

x = 4 cos²θ sinθ

y = 4 sin²θ cosθ

We have,

We can use the following conversions from polar to Cartesian coordinates:

x = r cosθ

y = r sinθ

To convert the polar equation r = 4 sin(θ)cos(θ) into Cartesian coordinates, we substitute r with its equivalent value 4 sin(θ)cos(θ) and use the above conversions:

x = (4 sinθ cosθ) cosθ

y = (4 sinθ cosθ) sinθ

Simplifying these expressions, we get:

x = 4 cos^2θ sinθ

y = 4 sin^2θ cosθ

The Cartesian equation of the polar equation r = 4 sin(θ)cos(θ) is:

x = 4 cos^2θ sinθ

y = 4 sin^2θ cosθ

or, in standard form:

x = 4xy

This is the Cartesian equation in terms of x and y, obtained by replacing sinθ and cosθ with x and y, respectively.
