Find the first three terms of the sequence below.
T, = n2 + 2n +9

Answers

Answer 1

Answer:

12, 17, 24

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is

T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12

T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17

T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24

Answer 2

Answer:

12, 17, 21 is the answer to the question

Gloria’s washing machine is broken. Since her machine is pretty old, she doesn’t want to spend more than $100 for repairs. A service call will cost $35 and the labor will be an additional $20 per hour. There are no other charges. What is the maximum number of hours that the repair person can work without the total cost exceeding $100?

Answers

Answer:

The actual answer is 3.25

Step-by-step explanation:

I just took the test

the maximum number of hours that the repair person can work is 3.5 hours

Given :

Gloria doesn’t want to spend more than $100.

A service call will cost $35 and the labor will be an additional $20 per hour

Let 'h' be the maximum number of hours the repair can take.

Lets find out the total cost for 'h' hours

35+ additional 20 per hour

[tex]35+20h[/tex]

The total cost should not exceed 100

[tex]35+20h \leq 100\\20h \leq 100-35\\20h\leq 65\\Divide \; by \; 20\\h\leq 3.5[/tex]

So , the maximum number of hours that the repair person can work is 3.5 hours

Or, equivalently:

P = 2(W + L)

Is this sentence Law of Detachment, Law of syllogism, or invalid

Answers

Answer:

The law of detachment and syllogism is valid here

Explanation:

The law of detachment and syllogism is associated with inductive reasoning. This law states that a conclusion is valid if the premise or hypothesis is valid, therefore if a then b. In others a results in b.

The law of detachment is denoted

[(a→b)∧a]→b

The law of syllogism derives from the law of detachment. Syllogism says that if a results in b and b results in c, then a results in c. In other words since a causes b and b causes c, then if a then c.

It is denoted

[(a→b)∧(b→c)]→(a→c)

In the above example, given: If you live in Orlando, then you live in Florida

Morgan does not live in Orlando, therefore it is concluded that he does not live in Florida

At a desert resort, the temperature at 7 a.m. was 3°C. The temperature increased by an average of 3.4°C each hour until it reached 30.2°C. How long did it take to reach this temperature?

Answers

Answer: It will take 8 hours to reach this temperature.

Step-by-step explanation:

Given: At a desert resort, the temperature at 7 a.m. was 3°C.

The temperature increased by an average of 3.4°C each hour until it reached 30.2°C.

Let x be the number of hours taken to reach 30.2°C..

As per given ,

Initial temperature +(average increase in temperature) (Number of hours) = 30.2

⇒3+3.4x=30.2

⇒3.4x=30.2-3

⇒3.4x=27.2

⇒ x=8    [Divide both sides by 3.4]

Hence, it will take 8 hours to reach this temperature.

You are given two points: (7,-6)(-4,27)

y=mx+b

y2-y1=x2-x1

x1=7

y1=-6

x2=-4

y2=27

27-(-6)/-4-7=27+6/-4-7=33/-11=-3

y=-3x+b

-6=-3(7)+b

-6=-21+b

b=15 so, y=-3x+15

Lily plans to paint a stencil design on the wall in her room the stencils has one part yellow 3 Part Blue and 4 parts are blue and 4 parts are white .The area of the the walls that she must paint is 480 square feet a quart of paint approximately covers 80 square feet .what is the minimum amount of paint that Lily needs to buy ​

Answers

Answer and explanation:

Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall

Remaining part of the wall left unpainted after using one whole paint

480-320= 160 square feet

Therefore paint required for remaining unpainted part

= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint

Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2

Total paint required is one and half

Or

We divide area of wall by area of wall covered by each quarter

480/80=6 quarters of paint

6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4

We still get same answer

= 1 1/2

Answer: A 1 quart yellow, 2 quarts blue, 3 quarts white

Step-by-step explanation:

if u divide 480 by 80 you will get 6 so u will only need 6 quarts of paint.

A 0.7 kg toy car accelerates at 0.5 m/s2. The FORCE is...
0.35 m/s2
0.35 kg
0.35 N

Answers

Answer:

[tex]\boxed {\boxed {\sf 0.35 \ N}}[/tex]

Step-by-step explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass of the toy car is 0.7 kilograms and the acceleration is 0.5 m/s²

[tex]m= 0.7 \ kg \\a= 0.5 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F=0.7 \ kg * 0.5 \ m/s^2[/tex]

Multiply.

[tex]F=0.35 \ kg*m/s^2[/tex]

1 kg*m/s² is equal to 1 Newton. The units for force are Newtons.Therefore, our answer of 0.35 kg*m/s² is also equal to 0.35 Newtons

[tex]F= 0.35 \ N[/tex]

The force of the toy car is 0.35 Newtons

Answer:

(45 kg)(4.1 m/s)2 = 120 N

If using the method of completing the square to solve the quadratic equation x2 + 15x + 4 = 0, which number would have to be added to "complete the square"?​

Answers

Answer:

The number which number would have to be added to "complete the square" is [tex]\mathbf{(\frac{15}{2})^2 }[/tex]

Step-by-step explanation:

We need to solve the equation [tex]x^2 + 15x + 4 = 0[/tex] by completing square method.

The general form is [tex]x^2+2(x)(y)+y^2=(x+y)^2[/tex]

Solving equation using completing square method

[tex]x^2 + 15x + 4 = 0[/tex]

We would be adding and subtracting 15/2 to make it a complete square

[tex]x^2+2(1)(\frac{15}{2} )+(\frac{15}{2})^2+4-(\frac{15}{2})^2=0[/tex]

So, now it can be written in form of [tex](x+y)^2[/tex]

[tex](x+\frac{15}{2})^2+4-\frac{225}{4}=0\\(x+\frac{15}{2})^2+4-\frac{225}{4}=0\\(x+\frac{15}{2})^2+\frac{4*4-225}{4}=0\\(x+\frac{15}{2})^2+\frac{16-225}{4}=0\\(x+\frac{15}{2})^2+\frac{-209}{4}=0\\(x+\frac{15}{2})^2-\frac{209}{4}=0[/tex]

So,using the method of completing the square to solve the quadratic equation x2 + 15x + 4 = 0 we get  [tex]\mathbf{(x+\frac{15}{2})^2-\frac{209}{4}=0}[/tex]

The number which number would have to be added to "complete the square" is [tex]\mathbf{(\frac{15}{2})^2 }[/tex]
