Find the value of integral(4 to 10) 2f(x)-3dx
We know that
[tex]\displaystyle \int_1^4 f(x) \, dx = 8[/tex]
[tex]\displaystyle \int_1^{10} f(x) \, dx = 17[/tex]
By linearity of the definite integral,
[tex]\displaystyle \int_4^{10} 2f(x) - 3 \, dx = 2 \int_4^{10} f(x) \, dx - 3 \int_4^{10} dx[/tex]
Presumably, you're aware that
[tex]\displaystyle \int_a^b dx = b - a[/tex]
for any two numbers a and b, so the last integral is simply 6.
From the known integrals, we also know
[tex]\displaystyle \int_1^{10} f(x) \, dx = \int_1^4 f(x) \, dx + \int_4^{10} f(x) \, dx[/tex]
[tex]\displaystyle 17 = 8 + \int_4^{10} f(x) \, dx[/tex]
[tex]\displaystyle \int_4^{10} f(x) \, dx = 9[/tex]
so
[tex]\displaystyle \int_4^{10} 2f(x) - 3 \, dx = 2\times9- 3\times6 = \boxed{0}[/tex]

Answer:
a. 16.9 m
b. 4.082 seconds
c. no
d. 2.041 seconds
e. 21.41 m
Step-by-step explanation:
A graphing calculator can help you answer these questions quickly and easily. The graph is attached.
__
a.Evaluate the function at t=3.
h(t) = -4.9t^2 +20t +1
h(3) = (-4.9×3 +20)×3 +1 = 5.3×3 +2 = 16.9
The baton will be at a height of 16.9 meters after 3 seconds.
__
b.The axis of symmetry of quadratic ax^2+bx+c is located at x=-b/(2a). The point of release and the later point at the same height will be symmetrically located about the axis of symmetry. The peak height will be on the axis of symmetry of the graph. That value of time is ...
tpeak = -20/(2(-4.9)) = 20/9.8 ≈ 2.041 . . . seconds
The baton will be at the release height again after 2×2.041 = 4.082 seconds.
__
c.As we saw in part (b), the maximum height will be when t=2.041 seconds. That height is found by evaluating the function for that value of t.
h(2.041) = (-4.9(2.041) +20)(2.041) +1 = 21.41 . . . meters
The baton will not reach a height of 25 meters.
__
d.We found this answer in part (b): 2.041 seconds to reach the maximum height.
__
e.We found this answer in part (c): 21.41 meters is the maximum height.
_____
Additional comment
The time at maximum height is 20/9.8 seconds = 100/49 = 2 2/49 seconds. In general, the answer values shown here are rounded to 4 significant figures. The graphing calculator rounds to 3 decimal places.
What fraction of a day (24 hrs) is 2 hours and 27 minutes.
So a day is made up of 24 hours. An hour is 60 minutes long. This means that 24 hours is 24 x 60 = 1,440 minutes in a day
2 hours and 27 minutes is 147 minutes long.
To find what fraction of a day it is do this equation \:
147/1,440 = approximately 0.102 of a day.
For a percentage, multiply by 100
0.102 x 100 = 10.2%

Find the length of the unknown segment (x) in each figure. Use theorem of secant segment and
external secant segment.
Answer:
1. x = 6 2. x = 9 3. x = 3
Step-by-step explanation:
Use Intersecting Secants Theorem:
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
1. AC and AD are secants that intersect at point A
So, AB x AC = AE x AD
[tex]x[/tex] x 15 = 6 x (6 + 9)
15[tex]x[/tex] = 90
[tex]x[/tex] = 6
2. KM and KN are secants that intersect at point K
So, KL x KM = KO x KN
10 x (10 + 8) = [tex]x[/tex] x 20
180 = 20[tex]x[/tex]
[tex]x[/tex] = 9
3. IG and IF are secants that intersect at point I
So, IH x IG = IJ x IF
[tex]x[/tex] x 39 = 9 x (9 + 4)
39[tex]x[/tex] = 117
[tex]x[/tex] = 3

(6x+1)(1−3x)
I did 3 strategies but they all ended up with 6x-17x^2-3x
Answer:
-18x²+3x+1
Step-by-step explanation:
To do this, we need to multiply 6x+1 by 1 and then 6x+1 by -3x:
(6x+1)(1)+(6x+1)(-3x)
Let's first do...
(6x+1)(1)
Distribute 1 to both of the terms inside of the parentheses:
6x(1)+1(1)
6x+1
Then...
(6x+1)(-3x)
Distribute the -3x to both of the terms inside of the parentheses:
6x(-3x)+1(-3x)
-18x²-3x
Then we add them together:
-18x²-3x+6x+1
-18x²+3x+1
a $48 game has a 9.6 percent sales tax. what is the final price jncluding tax?
Answer:

First let turn 9.6% into a decimal
0.096
Then,
48 x 0.096 = 4.608 {Round} 4.61
48 + 4.61=52.61
If $625 is invested at an interest rate of 7% per year and is compounded
continuously, how much will the investment be worth in 12 years? Use the
continuous compound interest formula: A = Pe^rt
Answer:
It will be worth approximately $ 1447.73.
Step-by-step explanation:
Since, the amount formula in compounded continuously,
Where,
P is the principal amount,
r is the rate per period,
t is the number of periods,
e is Euclid number,
Here, P = $ 625,
r = 7% = 0.07,
t = 12 years,
Hence, the amount after 12 years would be,

so 2-9=x
which digit is in the trillions place in 12,345,678,900,000
Answer:
2
Step-by-step explanation:
Answer:
The answer is
→ 2
Step-by-step explanation:
Let's look at the number.
12,345,678,900,000
And were asked to find the digit in the trillions place in this number.
Well, if we say it by word, then it will be:
twelve trillion, three hundred and forty-five billion, six hundred and seventy-eight million, and nine hundred thousand
Well, since were trying to find the digit in the trillionth place, then 12 trillion cannot be correct because the digits are in the 10 trillionth place. Ignore the 1 and you can see a number 2 in the trillionth place.
Therefore, your answer is 2.
Hope this helped! :^)

3. Here is a diagram of a softball field:
a. About how long is the fence around the field?
Outfield
Infield
b. About how big is the outfield?
110 ft
250 ft
(Hint: You can assume the infield is a circle.)
a. Length of the fence around the field = perimeter of quarter circle = 892.7 ft.
b. The area of the outfield is about 39,584 sq. ft..
What is the Perimeter of a Quarter Circle?Perimeter of circle = 2πr
Perimeter of a quarter circle = 2r + 1/4(2πr).
a. The length of the fence around the field = perimeter of the quarter circle fence
= 2r + 1/4(2πr).
r = 250 ft
Plug in the value
The length of the fence around the field = 2(250) + 1/4(2 × π × 250)
= 892.7 ft.
b. Size of the outfield = area of the full field (quarter circle) - area of the infield (cicle)
= 1/4(πR²) - πr²
R = radius of the full field = 250 ft
r = radius of the infield = 110/2 = 55 ft
Plug in the values
Size of the outfield = 1/4(π × 250²) - π × 55²
= 49,087 - 9,503
= 39,584 sq. ft.

Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle:
3x + 2 + 55 = 13x - 3 add like terms
3x + 57 = 13x - 3 export like terms to the same side
57 + 3 = 13x - 3x
60 = 10x divide both sides by 10
6 = x to find angle FAB replace x with 6
13*6 - 3 = 75
