Find the sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2.
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
where, a = first term of the geometric sequence.r = common ratio of the sequenceand n = nth term of the sequence.Therefore, the sum of the first 8 terms of the geometric sequence is;
S(8) = a + ar + ar² + ar³ + ar⁴ + ar⁵ + ar⁶ + ar⁷.
In essence;
since common ratio, r = 2 and first term, a = -2.5Therefore, we have;
S(8) = -2.5(1 + 2 + 2² + 2³ + 2⁴ + 2⁵ + 2⁶ + 2⁷)S(8) = -2.5(255)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

let f(x)=-2x-7 and g(x)=-4x+3 find (f°g)(-5)
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

What is the measure of angle 1? Put the number only.
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
How does the perimeter and area change
if each dimension is doubled? Explain!
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.

What is the equation of the line that passes through the point (-6, -5) and has a slope of -3/2?
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)

A car is traveling at 40 mi/hour. What is the car's speed in feet per second?
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.

Barty is going to flip a coin three times. What is the probability that he will see at least
two tails? Can you use a Probability Area Model for this situation?
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
how to find the mean for negative numbers
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

9 to the power 18 = 27 to the power x work out the value of x
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
