Answer:

By doubling the dimension R, we'll actually change the area by a factor of 4 (it will become four times as large). Notice that this same change to the radius would only change the original circle's perimeter (2πR) by a factor of 2.

Answer:

58.8 feet per second

Step-by-step explanation:

At 40 miles per hour, you are traveling 58.8 feet per second. To convert miles per hour to feet per second, multiply the miles per hour figure by 1.47. There are 5280 Feet in a mile and 3600 Seconds in an hour. If you divide 5280 Feet by 3600 Seconds (5280 FT /3600 SEC.), you get 1.47.

Hope that helps :)

Answer:

angle 1 = 120 degree

Step-by-step explanation:

75 degree + 45 degree = angle 1 (sum of two opposite interior angles is equal to the exterior angle formed)

120 degree = angle 1

Answer:

120

Step-by-step explanation:

75 + 45 = 120

The triangle adds up to 180.

180 - 120 = 60

Therefore the inside of the triangle is 75, 45, and now 60 which all adds up to 180.

--

Now to find Angle 1.

180 - 60 = 120

With Angle 1 being 120

Answer:

1/2

Step-by-step explanation:

For three coin tosses, the posible outcomes are:

[(HHH), (HHT), ( THH), (HTH), ( THT), (TTH), (HTT), (TTT)

The outcomes where there are at least 2 tails are:

(TTT), (TTH), (THT), (HTT)

So, the probability that the coin will land tails at least 2 times is 4/8 or 1/2

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒  3 ^ 3x × 3^x = 3²            [ since  ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3²                [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2                      [ since  If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

 ∴ x = 1 / 2

I hope this helps you.

Answer:

y=3/2x+3/2

Step-by-step explanation:

point at (-6,-5)

slope = m = 3/2

y = mx+b

(-6)=(3/2)(-5)+b >>> substituting x & y to solve for b

-6 = (-15/2)+b >>> simplify previous equation

-6 + (15/2) = b >>> isolate and solve for m

3/2 = b

therefore, the equation of the line passing through the point (-6,-5) with a slope of 3/2 is y=(3/2)x+(3/2)

Answer:

the last choice

Step-by-step explanation:

i mean, you judt gotta find the points of the letters.

you can first find the coordinates of point A, which is 3, 2

based off of that, the rest of the answer choices don't have A as 3, 2.

so, with Process of Elimination, its the last one.

Answer:

???? none- they're all the same and there's no 1/3

Answer:

-53

Step-by-step explanation:

f°g = f(g(x))     Remember this because this notation is less confusing for you.

Step 1. Plug g(x) in all values of x in the function f(x).

f(g(x)) = -2(-4x+3) -7

Step 2. Distribute the -2

-2(-4x+3) = 8x -6

f(g(x)) = 8x-6-7

Step 3. Simplify by subtracting -6 - 7

f(g(x)) = 8x-13

Step 4. Plug in -5 for x

8(-5) - 13 = -40 - 13 = -53

Answer:

33450

Step-by-step explanation:

You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.

For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers

-9+-5+-4+-3+-1=-22

-22/5=-4.4

the mean for those set of numbers is -4.4

Answer:

75

Step-by-step explanation:

5(6+9)

Times the five by the numbers in the bracket

30 + 45

= 75

Answer:

75

Step-by-step explanation:

5 x 6 = 30

5 x 9 = 45

30 + 45 = 75

The sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2 is: -637.5

The nth term of a geometric sequence is given mathematically as;

T(n) = ar^n

Therefore, the sum of the first 8 terms of the geometric sequence is;

In essence;

Therefore, we have;

S(8) = -637.5.

Therefore, the sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2 is: -637.5
