A geometric sequence has a4 = 4 and a5 = 7. What is a1 ? Your answer
Answer:
4⁴/7³ or 256/343Step-by-step explanation:
Given GP with
a₄ = 4a₅ = 7a₁ = ?Let the common difference is r, then
a₅ = a₄ra₁r³ = 4a₁r⁴ = 7Solve for r and then a₁:
4r = 7 ⇒ r = 7/4a₁(7/4)³ = 4a₁ = 4*(4/7)³ = 4⁴/7³ = 256/343Simplify the square root of:
√32
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
factor the square root of 32
to get a total of 32, you do 4 times 4, which is 16
16 times 2 =32
16 is a perfect square so it's outside of the square root symbol, but you can't find the square root of 2 without it being irrational.
So,
final answer: 4[tex]\sqrt{2}[/tex]

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³

A pirate in search of a treasure hikes three days in a row. He hikes 12.5 km to his destination on the first day, 18 km to his destination on the second day, and 14 km to his destination on the third day. He hikes 1 km/h slower on the first day than on the second day, and 1 km/h faster on the first day than on the third day. The third day's hike takes 30 minutes longer than the second day's hike. How long does the pirate search (across all three days) if he spends 2 hours digging for treasure at each destination?
Answer:
15hrs
Step-by-step explanation:
We can start by expressing the speed of the second trip as x. This means that the first trip must be x-1, and second (x-1)-1=x-2. Next we can form an equation with the information that the third day hike takes 30 min longer than second day hike. Since we now the distance of both days, we can express them in time. So... [tex]\frac{18}{x}+\frac{1}{2}=\frac{14}{x-2}[/tex] ... We can solve by finding a LCM of all three expressions. Doing so we get 2x(x-2). Now multiplying out with the new denominators, we get 36(x-2)+x(x-2)=28x. Solving as a quadratic equation, the solution comes out to be x=6, x=-12. But as speed can't be negative, only solution is x=6. Now we get the speed of each day's hike. First day=x-1=5, second day=6, third day =x-2=4. Finding the time is simple, just do distance/speed. First day=12.5/5=2.5hrs. Second day=18/6=3hrs. Third day=14/4=3.5hrs. Adding total hrs up... 2.5+3+3.5=9. Finally step is accounting for the 2hr digging time per day. 2hrs*3= 6hrs. 6hrs+9hrs=15hrs. Hope this helps!
A soccer player is 30 feet from the goal line. He shoots the ball directly at the goal.
The goal is 8 feet high. What is the maximum angle of elevation at which the player
can shoot the ball and still score a goal?
Answer:
14.93°
Step-by-step explanation:
Using trigonometry :
From the diagram attached :
Angle of elevation = x
To obtain the value of x
Tan x = opposite / Adjacent
Tan x = 8 / 30
Tan x = 0.266666
x = tan^-1(0.26666)
x = 14.93°
Therefore, the angle of elevation is 14.93°

In 2007, the value of a house was £119,995 From 2007 to 2018, house prices decreased by 9.4%. How much has the value of the house decreased by?
Answer: £11,279.53
Step-by-step explanation:
Given
In 2007, the price of the house was £119,995
Price decreases by 9.4%
[tex]\Rightarrow \text{Current Price}=\text{Old Price}-9.4\%\text{Old Price}\\\Rightarrow 119,995-9.4\%\ \text{of}\ 119,995\\\Rightarrow 119,995(1-0.094)=119,995\times 0.906\\\Rightarrow 108,715.47[/tex]
Price decreased by 119,995-108,715.47=£11,279.53

Which quadratic function has a vertex point of (3,5) and passes through the
point (-2,55)?
9514 1404 393
Answer:
f(x) = 2(x -3)² +5
Step-by-step explanation:
For vertex (h, k) and scale factor 'a', the vertex form is ...
f(x) = a(x -h)² +k
We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.
55 = a(-2 -3)² +5
50 = 25a . . . . . . . . subtract 5
a = 2 . . . . . . . . . . . divide by 25
So, the function is ...
f(x) = 2(x -3)² +5
__
In standard form, that will be ...
f(x) = 2x² -12x +23

a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?
Answer:
You have 90 pages left.
Step-by-step explanation:
1/4 × 120 = 30 pages read
Therefore
120- 30
=90 pages left to read
Answer:
You read 30 pages of the book.
You have 90 pages left.
Step-by-step explanation:
120 total pages
⇒ 120 = 100%
[tex]\frac{1}{4}[/tex] pages have been read
⇒ [tex]\frac{1}{4}[/tex] = 25%
[tex]\frac{3}{4}[/tex] remaining
⇒ [tex]\frac{3}{4}[/tex] = 75%
120 x .25 = 30 pages read
120 x .75 = 90 pages unread
30 + 90 = 120

Answer:
6/10
Step-by-step explanation:
6/10 is equal to 3/5 because you can multiply 3/5 times 2. So multiply the numerator(3) times 2, which is 6, then multiply the denominator(5) times 2 as well, which is 10.
Hope this helped!

In degrees, what is the measure of MFE?
Answer:
30°
Step-by-step explanation:
It tells us that MFE is equal to (x + 6)° so we need to find x
The angle accross from MFE is RFT. These angles are congruent, because they are a vertical pair. So RFT is also equal to (x + 6)°
The angle RFT and PFR combined form a right angle. This means that RFT + PFR = 90°.
They told us that PFR = (3x - 4)°
so that means that (x + 6) + (3x - 4) = 90°
Knowing that we can just solve the equation by combining like terms
4x + 2 = 90
Subtract two from both sides
4x = 88
And then divide by 4
x = 22
Now we can plug in 22 in the original equation to find MFE
22 + 6 = 30
so MFE = 30°

Find the LCD of the fractions. Multiplying the denominators 3 and 4 together, we get LCD = 12.
Rewriting the mixed numbers, we get
3 2/3 = 3 8/12 and 3 1/4 = 3 3/12
So the original equation becomes
(3 8/12)x + 3 3/12 = 6
We must now combine like terms: subtract 3 3/12 from both sides of this equation, obtaining:
(3 8/12)x = 6 - 3 3/12, or
(3 8/12)x = 2 9/12. Converting the mixed numbers into improper fractions, we get:
(44/12)x = 33/12. Multiplying both sides by 12 yields 44x = 33
and so x = 33/44 = 3/4
x = 3/4
Alternatively, convert the original mixed numbers into improper fractions right away. Then the original 3 2/3 x+3 1/4=6
becomes (11/3)x + 13/4 = 72/12, or
(44/12)x + 39/12 = 72/12
Multiplying all three terms by 12 yields:
44x + 39 = 72, which simplifies to 44x = 33, or x = 3/4
the diameter of a cylindrical water tank is 8ft and its height is 11 ft what is the volume of the tank?
Using the formula for the volume of a right cylinder, we can determine the volume of the water tank.
Formula for the volume of a right cylinder: V = π (d /2)^2
h = π * (8/2)^2 ·11 ≈ 552.92
Therefore, the volume of the tank is approximately 552.92 ft.
