Answer 1

Answer:

the roots are 5 and 1/2

Step-by-step explanation:

a = 2

b = -11

c = 5

Plug values into formula: (-b ± √b² - 4ac) ÷ 2a

the discriminant comes out to be √81

(11 + 9) / 4 = 5

(11 - 9) / 4 = 1/2

Answer:

[tex] \arc{PNM} = 222 [/tex]

Step-by-step explanation:

Central angle = measure of the arc it subtends

Therefore:

[tex] \arc{PN} = \arc{PM} = 138 [/tex]

A full circle = 360°

So,

[tex] \arc{PN} + \arc{PM} + \arc{NM} = 360 [/tex]

Plug in the values

[tex] 138 + 138 + \arc{NM} = 360 [/tex]

[tex] 276 + \arc{NM} = 360 [/tex]

[tex] \arc{NM} = 360 - 276 [/tex] (subtraction property of equality)

[tex] \arc{NM} = 84 [/tex]

[tex] \arc{PNM} = \arc{NM} + \arc{PN} [/tex]

Plug in the values

[tex] \arc{PNM} = 84 + 138 [/tex]

[tex] \arc{PNM} = 222 [/tex]

A deck of cards contains RED cards numbered 1,2,3,4,5,6 and BLUE cards numbered 1,2,3. Let R be the event of drawing a red card, B the event of drawing a blue card, E the event of drawing an even numbered card, and O the event of drawing an odd card. Drawing the Blue 2 is one of the outcomes in which of the following events?

a. R OR O
b. B AND O
c. R OR E
d. R AND O
e. R′
f. E

Answers

Answer: c. R OR E

e. R′

f. E

Step-by-step explanation:

Outcomes for Red card ={1,2,3,4,5,6} = 6

Outcomes of Blue card = {1,2,3} =3

R = event of drawing a red card, B = event of drawing a blue card, E=event of drawing an even numbered card, and O = event of drawing an odd card.

Then, R= {1R,2R,3R,4R,5R,6R} , B= {1B,2B,3B}

E={2R, 4R, 6R , 2B}

O = {1R, 3R, 5R, 3B}

R or O = { 1R,2R,3R,4R,5R,6R ,3B} [all elements of R and O]

B and O = {3B} [all elements common in B and O]

R or E = {1R,2R,3R,4R,5R,6R,2B }

R and O = {1R, 3R, 5R} [all elements common in R and O]

R' = B= {1B,2B,3B} [all elements except R]

Blue 2 = 2B belongs to B, R or E, R' and E.

Correct options are c. e. f.

Answer:

Blue 3

B AND O

Which best describes a difference between SALT I and SALT II?

SALT I limited weapons, while SALT II limited launchers.
SALT I expanded the production of arms, while SALT II limited production.
SALT I allowed the sides to trade weapons, while SALT II expanded this practice.
SALT I limited military forces of each country, while SALT II allowed their growth.

Answers

The difference between SALT I and SALT II is SALT I limited weapons, while SALT II limited launchers. So, correct option is A.

The Strategic Arms Limitation Talks (SALT) were a series of negotiations between the United States and the Soviet Union to limit and reduce the number of nuclear weapons and delivery systems.

SALT I was signed in 1972 and focused on limiting the number of ballistic missiles and bombers each side could possess. It also established a system for verifying compliance with the treaty.

SALT II was signed in 1979 but was never ratified by the U.S. Senate due to increased tensions between the two countries. SALT II aimed to further reduce the number of strategic nuclear weapons and delivery systems, but unlike SALT I, it focused on limiting the number of launchers rather than weapons themselves.

Therefore, the correct answer is A.

Adam: 52.26°

Step-by-step explanation:

Use Cosine Rule, [tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex], to find the angle of both players.

✔️Angle of Carlos:

Let the angle be C,

a = 50 ft

b = 40 ft

c = 24 ft

Plug in the values into the equation

[tex] Cos(C) = \frac{50^2 + 40^2 - 24^2}{2*50*40} [/tex]

[tex] Cos(C) = \frac{3,524}{4,000} [/tex]

[tex] C = Cos^{-1}(\frac{3,524}{4,000}) [/tex]

C = 28.24° (nearest hundredth)

✔️Angle of Adam:

Let the angle be C,

a = 30 ft

b = 22 ft

c = 24 ft

Plug in the values into the equation

[tex] Cos(C) = \frac{30^2 + 22^2 - 24^2}{2*30*22} [/tex]

[tex] Cos(C) = \frac{808}{1,320} [/tex]

[tex] C = Cos^{-1}(\frac{808}{1,320)} [/tex]

C = 52.26° (nearest hundredth)

The population of a community of foxes is observed to fluctuate on a 10-year cycle due to variations in the availability of prey. When population measurements began (t=0, the population was 35 foxes. The growth rate in units of foxes>>year was observed to be P′(t)=5+10sinπt/5

a. What is the population 15 years later? 35 years later?
b. Find the population P(t) at any time t≥0.

Answers

Answer:

Population 15 years later P(15) = 100 + 50/π

Population 35 years later P(35) = 200 + 50/π

Population any t ≥ 0 P(t) = 35 + 50 /π + 5*t + 10*cos(π*t/5)

Step-by-step explanation:

P´(t) = 5 + 10*sinπt/5 ⇒ dP/dt = 5 + 10*sinπt/5

dP = ( 5 + 10*sinπt/5 ) *dt

P(t) = ∫ ( 5 + 10*sinπt/5 ) dt

P(t) = 5*t + 10 * ∫ sinπ*t/5* dt

P(t) = 5*t - 10*5/π *cos πt/5 + k

To determine k t = 0 P(t) = 35

P(0) = 5*0 - 50/π (1) + k

35 = - 50/π + k

k = 35 + 50/π and

P(t) = 5*t + 10*cos(π*t/5) + 35 + 50/π

b)P(t) = 35 + 50 /π + 5*t + 10*cos(π*t/5) (1)

a) Population 15 years later

P(15) = 35 + 50/π + 5*15 - 10

P(15) = 100 + 50/π

Again from equation (1)

P(35) = 35 + 50 /π + 5*35 + 10*cos(35*π/5)

P(35) = 35 + 50/π + 175 + 10*cos (7*π )

P(35) = 210 + 50/π - 10

P(35) = 200 + 50/π

Jayla paints a book case. She uses 1 5/6 cups of paint on the outside of the book case and 3/8 cup of paint on the inside. How many cups of paint does Jayla use altogether

Answers

Answer:

Answer: Kayla used 2&5/24 cups of paint all together.

Step-by-step explanation:

Kayla paints a bookcase by using

1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.

She also used 3/8 cup of paint on the inside.

Therefore, the total number of cups of paint that Kayla used all together would be cups of paint:

[tex]11/6 + 3/8 = (44 + 9)/24 = 53/24[/tex]

Converting to mixed fraction, it becomes

2 and 5/24 cups of paint
