if you drove 200 miles at an average speed of 55 miles per hour, how long did it take you to drive 200 miles? pls help

Step-by-step explanation:

an = 2n^2 - 3 · Anonymous. -1, 5, 15, 29, 47, ... an = 2 n^2 - 3.

The required nth term will be 2n² - 3 in the given quadratic sequence.

Sequences are defined as an arrangement of numbers that is in a particular order.

The first 5 terms of a quadratic sequence are following as:

-1, 5, 15, 29, 47,

We have to determine the nth term of the given sequence.

As per the given question, we have

-1, 5, 15, 29, 47,

We can rewrite the above numbers in the sequence as

first term = -1 = 2(1)²-3,

second term = 5 = 2(2)²-3,

3d term = 15 = 2(3)²-3,

4th term = 29 = 2(4)²-3,

5th term = 47 = 2(5)²-3

Similarly, nth term = 2n² - 3

Therefore, the required nth term will be 2n² - 3 in the given quadratic sequence.

Answer:

not a function. domain = -2, 3, 8 (you don't have to write them in any specific order and you also don't need to write -2 twice)

Step-by-step explanation:

to be a function, all of the x's must be different

Length in units:

Use phytogoras theorem or measure it by a ruler if your using a graph paper

AB = 5.65 units

AC = 5.83 units

CB = 1.41 units

Perimeter =5.65 + 5.83 + 1.41 = 12.89 units

Area = 1/2 * 1.41 * 5.65 = 3.98units

=》29x + 4 < 76

=》29x < 76 - 4

=》29x < 72

=》x < 72/29

Hope it helps ⚜

[tex]29x +4 <76 \\\\\implies 29x < 76-4\\\\\implies 29x< 72\\\\\implies x<\dfrac{72}{29}\\\\\\\text{Decimal,} ~~~x<2.49\\\\\text{Interval,}~~ \left(-\infty, \dfrac{72}{29} \right)\\\\[/tex]

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Same thing as 2 x 2 = 4

The actual lenght will be 6 fee

The actual width will be 4 feet

The scale factor that Jenna's father used to go from the drawing to the actual house is 1.5

The perimeter of the floor is 20 feet

The area of the first floor that Jenna's that father built is 24ft²

Given the conversion factor 2inches = 1feet

1) If Jenna's father is going to use the blueprint above to make a playhouse for her and the length of the entire first floor is 12 inches, the actual length in feet is expressed as:

12 inches = x

2inches = 1feet

_____________________________

2x = 12

x = 6 feet

Hence the actual lenght will be 6 feet

2) If the width of the entire first floor is 8 inches, the actual width is expressed as;

8 inches = x

2inches = 1feet

_____________________________

2x = 8

x = 4 feet

Hence the actual width will be 4 feet

3) Thee scale factor will be the ratio of the length to the width as shown:

Ratio = length/width

Ratio = 6/4

Ratio = 3/2

Hence the scale factor that Jenna's father used to go from the drawing to the actual house is 1.5

4) The perimeter of the floor = 2(L + W)

Perimeter = 2(6 + 4)

Perimeter = 2(10)

Perimeter of the floor is 20 feet

5) Area of the floor = length * width

Area of the floor = 6ft * 4ft

Area of the floow = 24ft²

Hence the area of the first floor that Jenna's that father built is 24ft²

Answer:

m=4/3

Step-by-step explanation:

(a)

[tex]SI = \frac{PRT}{100} \\ = \frac{1800 \times 5 \times 1}{100} \\ = 18 \times 5 \\ = 90[/tex]

Total amount = SI + Amount

= 90 + 1800 = $1890

(b)

[tex]SI = \frac{PRT}{100} \\ = \frac{2600 \times 12 \times 3}{100} \\ = 26 \times 12 \times 3 \\ = 26 \times 36 \\ = 936[/tex]

Total amount = SI + Amount

= 936 + 2600 = $ 3236

(c)

[tex]SI = \frac{PRT}{100} \\ = \frac{3125 \times 15 \times 0.2}{100} \\ = 93.75[/tex]

Total amount = SI + Amount

= 93.75 + 3125 = $ 3,218.75

The simple interest on $1800 is $90.

The simple interest on $2600 is $936.

The simple interest on $3125 is $93.75

Simple interest is when interest is earned only on the amount of money deposited.

Simple interest  = amount deposited x time x year

1800 x 0.05 x 1 = $90

2600 x 0.12 x 3 = $936

3125 x 0.15 x (73/365) = $93.75

Step-by-step explanation:

so, to repeat, the radius r of the circle is 87 cm.

the area of a circle is

pi×r²

so, in our case

A = pi×87² = pi×7569 = 23,778.7148... cm²

so, how to give this answer with only 3 significant figures ?

as you can see, there are already 5 figures before the decimal point.

3 attempts :

1. 3 significant figures after the decimal point : 23778.715 cm²

2. scientific notation with 3 SF : 2.38×10⁴ cm²

3. converting to m² (1m² = 10000cm²) : 2.38 m²

The formula in terms of sum of two angle measures is c 3[sin(90 + 60)]t

Since the alternating current i in amperes after t seconds is i = 3(sin150)t.

We want to write 150 as the sum of two angles measures.

So, 150 = 90 + 60.

So, the current i = 3(sin150)t

i = 3[sin(90 + 60)]t

So, the formula in terms of sum of two angle measures is c 3[sin(90 + 60)]t
