Is 5-x^2=6 a true equation?

Answer:

A(3, 0)

B(-5, 6)

C(-2, -3)

Statement J is the answer

Answer:

f = ~-6.09 rounded to the hundredth

Step-by-step explanation:

-2.5f + 0.2f - 11= 3

-2.3f - 11 = 3

-2.3f = 14

f = -6.0869

Answer:

Its 12 U^U

Step-by-step explanation:

subtract 9x from each side

3y = 12 - 9x

divide by 3

y = 4-3x

f(x) = 4-3x

She spent 142.65 for baskets, 252.50 for flowers and 185 * 0.07 or 12.95 for ribbons for a total outlay of 408.10. Since she made 30 baskets, that is 408.10/30 = 13.60 1/3 per basket.

If she sold all 30 for 25.99 each, that is 779.70 for a profit of 361.60

Answer:

x = 21

Step-by-step explanation:

For the complementary angles, the sum of two angles is equal to 90 degrees.

ATQ,

3x+2+x+4 = 90

Taking like terms together,

3x+x+6=90

4x+6=90

4x = 84

x = 21

So, the value of x is equal to 21.

Answer:

(i) The lateral area of the right prism is 144 square units

(ii) The volume of the right prism is 249.42 cubic units.

Step-by-step explanation:

The lateral area of the right prism is calculated as;

Lateral area = perimeter of the base x height

Given;

a side of the hexagon base, s = 4

height of the prism = 6

perimeter of the hexagon = 6s

Lateral area = (6 x 4) x 6

Lateral area = 144 square units

Volume of the right prism is calculated as;

V = base area x height

base area of a hexagon = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2}[/tex]

Volume of the right prism = [tex]\frac{3\sqrt{3} \ \times \ s^2}{2} \ \ \times \ \ h\\\\[/tex]

[tex]V = \frac{3\sqrt{3} \ \times \ (4)^2}{2} \ \ \times \ \ 6\\\\V = 249.42 \ cubic \ units[/tex]

The number of feet that represents the length of the copier room measures 7 inches on the floor plan will be 21 feet.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

On a scale drawing of an office space floor plan, 1 inch represents 3 feet. Then the scale factor is given as,

Scale factor = 3 / 1

Scale factor = 3 feet per inches

The length of the copier room measures 7 inches. Then the number of feet that represents 7 inches is given as,

⇒ 7 x 3

⇒ 21 feet

The number of feet that represents the length of the copier room measures 7 inches on the floor plan will be 21 feet.

Wrong answer but unique technique to consider: i think i inversed the ratio but i think its right

Pi = circumference/diameter

X/18 centimeters =pi

X is whole circumference 18pi cm you need to convert radians to degrees and get partial arc1 pi is 180 degrees so ratio of

Was the error inverse ratio 96/180?

180/96*18

Error here factor of 72 not 96

18*2*3*3*10/2*3*12 [edit factor should be 2 4 12 ]cancel out factors to reduce

180/4 =45cm

Correction

180*3/4*4

So answers i got are 45 cm corrected as 33.75 cm still way more than total circumference of 18pi 56cmapprox and 9.6cm both are wrong according to calculator online

Please note I canceled out pi by using is degree ratio

Double check i may be wrong

Step-by-step explanation:

Answer:

Solution, we have,

Degree measure ([tex]\theeta[/tex][tex]\alpha[/tex]) = 96° = 96[tex]\pi[/tex]/180

Radius (r) = 9cm

Length of arc (l) = ?

Now,

∝ = l /r

or, [tex]\frac{96\pi }{180}[/tex]  =[tex]\frac{l}{9}[/tex]

or, l =[tex]\frac{(96\pi )(9)}{180}[/tex]  =4.8[tex]\pi[/tex]cm

This question is incomplete, the complete question is;

A university is trying to determine what price to charge for tickets to football games. At a price of ​$24 per​ ticket, attendance averages 40,000 people per game. Every decrease of ​$4 adds 10,000 people to the average number. Every person at the game spends an average of ​$4 on concessions. What price per ticket should be charged in order to maximize​ revenue? How many people will attend at that​ price?

Answer:

a) price per ticket = $18

b) 55,000 will attend at that price

Step-by-step explanation:

Given that;

price of ticket = $24

so cost of ticket = 24 - x

every decrease of $4 adds 10,000 people

for $1 adds 2,500 people

Total people = 40000 + 2500x

Revenue function = people × cost + people × 4

so

R(x) = (40000 + 2500x)(24 - x) + (40000 + 2500x)4

R(x) = 960,000 - 40000x + 60000x - 2500x² + 160,000 + 10000x

R(x) = 1120000 + 30000x - 2500x²

R(x) = -2500x² + 30000x + 1120000

now for maximum revenue; R'(x) is to zero

so

R'(x) = d/dx(  -2500x² + 30000x + 1120000 ) = 0

⇒ -5000x + 30000 + 0 = 0

⇒ -5000x + 30000 = 0

⇒ 5000x = 30000

x = 30000 / 5000

x = 6

R'(X) = -5000 < 0 ⇒ MAXIMUM

∴ Revenue is maximum at x = 6

so cost of ticket ;

price per ticket = (24 - x) = 24 - 6 = $18

so price per ticket = $18

Number of people = 40000 + 2500x

= 40000 + (2500 × 6)

= 40000 + 15,000

= 55,000

Therefore, 55,000 will attend at that price
