Answer:

f(x) = -x^2 + x + 13 find f(9) = -59

Hope this helps :)

Answer:

f(9)= -59

Step-by-step explanation:

First, put 9 into x; which gives you...

f(9)= (-9)^2+9+13

f(9)= -81+9+13

f(9)= -59

Answer:

[tex]2\sqrt{21}[/tex]

Step-by-step explanation:

We can multiply the two irrational terms, getting [tex]\sqrt{84}[/tex].

We see that 4 is a factor of 84, so we can rewrite [tex]\sqrt{84}[/tex] as [tex]\sqrt{4 (21) }[/tex]. We can take the 4 out, getting [tex]2\sqrt{21}[/tex].

Answer:

y = 3x

Step-by-step explanation:

Parallel lines have the same slope, so the slope of this new line will be the same as the given one.

For a line to pass through the origin it needs to have a y intercept of 0, because the origin is the point (0,0).

Answer:y = 3x

Direct variation occurs when a variable varies directly with another variable. That is, as the x-variable increases, the y-variable also increases.

The ratio of between y-variable and x-variable would be constant.

Direct variation can be represented by the equation, [tex] y = xk [/tex], where k is a constant. Thus,

[tex] \frac{y}{x} = k [/tex]

From the table given, it seems, as x increases, y also increases. Let's find out if there is a constant of proportionality (k).

Thus, ratio of y to x, [tex] \frac{0.50}{1} = 0.5 [/tex]

k = 0.5.

If the given table of values has a direct variation relationship, then, plugging in the values of any (x, y), into [tex] \frac{y}{x} = k [/tex], should give us the same constant if proportionality.

Let's check:

When x = 2, and y = 1:

[tex] \frac{y}{x} = k [/tex],

[tex] \frac{1}{2} = 0.5 [/tex],

When x = 3, y = 1.5:

[tex] \frac{1.5}{3} = 0.5 [/tex],

When x = 5, y = 2.50:

[tex]\frac{2.5}{5} = 0.5[/tex],

The constant of proportionality is the same. Therefore, the relationship forms a direct variation.

Answer:

Direct variation occurs when a variable varies directly with another variable. That is, as the x-variable increases, the y-variable also increases.

Answer:

Answer:

True

Step-by-step explanation:

The other person is wrong

The value π/16 is a solution for the equation 2cos²(4x) – 1 = 0, is true.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The value π/16 is a solution for the equation 2cos²(4x) – 1 = 0.

Put x = π/16, we have

2cos²(4x) – 1 = 0

2cos²[4 (π/16)] – 1 = 0

2cos²(π/4) – 1 = 0

We know that cos (π/4) = 1/√2

2(1/√2)² – 1 = 0

  2 (1/2) – 1 = 0

           1 – 1 = 0

                0 = 0

Thus, the statement is true.

Step-by-step explanation:

Answer:

m = -6

Step-by-step explanation:

3m= 5(m + 3)-3

Distribute

3m = 5m +15 -3

Combine like terms

3m = 5m +12

Subtract 5m

3m-5m = 5m+12-5m

-2m = 12

Divide by -2

-2m/-2 = 12/-2

m = -6

Interchange the variables

[tex]x=\frac{y}{y-2}[/tex]

solve for y, multiply equation by y-2.

[tex]y=\frac{2x}{x-1}\\[/tex]

replace y with [tex]f^{1}[/tex](x)

Answer: Constructing a circle of any arbitrary radius.

Step-by-step explanation:

When trying to construct an inscribed square and also an inscribed equilateral triangle, one step which is same for both procedures is the construction of a circle with an arbitrary radius because both shapes would be inscribed inside the circle been drawn. So the step involving the drawing of the circle is same for both.

Answer: Set the compass width to the radius of the circle.

Step-by-step explanation:

Step-by-step explanation:

(A) (In the fig. triangle represented by small triangle with angle of elevation 30° and height h1 ) ( Using this explanation since the figure is not marked)

[tex]tan30 = \frac{h1}{40} [/tex]

[tex]h1 = \frac{40}{\sqrt{3} } m[/tex]

(B) (In the fig. triangle represented by small triangle with angle of depression 58° and height h2 )

[tex]tan58 = \frac{h2}{40} [/tex]

[tex]h2 = 64m[/tex]

(C)

[tex]Height \: of \: Building \: A = h2 = 64m[/tex]

Step-by-step explanation:

Answer:

h = 61.83 feet

Step-by-step explanation:

length of string from Hector to kite = c = 86 feet.

and 4 feet off the ground.

angle A = 42° 15' 30"

req'd:  how high is the kite?

angle A = 42° + 15' (1° / 60') + 30"(1° / 3600'')

angle A = 42.26

to get the side a (height of kite) 4 feet above ground: use Sin(A) = opp / hyp

Sin(A) = a / c

Sin(42.26) = a / 86

a = Sin(42.26) * 86

a = 57.83 feet

therefore, the height of the kite from the ground = h = 57.83 + 4

h = 61.83 feet

OK please follow me friends

Step-by-step explanation:

Yaa's age = 10 years

Kwasi's age = 20 years

They share the mangoes in the ratio of their ages

That's

10 : 20 = 1 : 2

Total number of mangoes = 60

Total parts = 1 + 2 = 3

= 2 × 20

Hope this helps you

Answer:

Yaa gets 20 oranges while Kwasi gets 40 oranges

Step-by-step explanation:

We will add both ages= 10+20=30

Then we will pick yaa's age/ their total ages multiplied by the amount of oranges= 10/30 * 60

yaa will get= 600/30 = 20 oranges

Then Kwasi's age/their total ages multiplied by the amount of oranges= 20/30* 60=

1200/30= 40 oranges

Answer:

1. Yes, 1 position backwards

2. Yes, a free blueberry muffin and a free slice of carrot cake

b. Yes

3. 19 prizes

Step-by-step explanation:

The given conditions for winning a prize are as follows;

The prize that every 5th customer gets = A free bagel

The prize that every 9th customer gets = A free blueberry muffin

The prize that every 12th customer gets = A free slice of carrot cake

Therefore, the prizes will go to the 5th, 9th, 10th, 12th, 15th, 18th, 20th, 24th, 25th, 27th, 30th, 35th, 36th, 40th, 45th, 48th, and 50th positon customers

1. Diego being 23rd is right for thinking that he should get farther back in line in order to get a prize

He should get one position behind to 24th position

The reason is because prizes will be given to every 12th customer, and the 24th customer is the second 12th customer

2. Yes Jada will get a price as her position corresponds to the consecutive 9th and 12th customers position

Jada will get a free blueberry muffin and a free slice of carrot cake

b. It is possible for Jada to get more than one prize

This is so because her position coincides with the consecutive 9th and 12th customers position

3. The number prizes that Lin's uncle gives away are;

5th, 9th, 10th, 12th, 15th, 18th, 20th, 24th, 25th, 27th, 30th, 35th, 36th, 40th, 45th, 48th, and 50th = 17 prizes

including 1 extra prize each for the 36th and 45th customers which gives a total of 19 prizes.
