area: about
ft2
Answer:
78.6
Step-by-step explanation:
Area of circle = Pi*r^2
r=5
for pi use calculator or pi=3.142
area =Pi*r2=(3.142)*5^2=(3.142)*25=78.55 = 78.6 (1 decimal place which is same with tenth)

Let theta equal 17pi/12
Part A: Determine tan θ using the sum formula. Show all necessary work in the calculation. (5 points)
Part B: Determine cos θ using the difference formula. Show all necessary work in the calculation. (5 points)
The tan θ and cos θ values of 17π/12 are illustrations of trigonometry ratios
The values of tan θ and cos θ are 2 + √3 and (√2 - √6)/4, respectively
Part A: tan θ using the sum formulaWe have:
θ = 17π/12
Express as sum
θ = 9π/12 + 8π/12
Simplify
θ = 3π/4 + 2π/3
The above becomes
tan(17π/12) = tan(3π/4 + 2π/3)
Using the sum formula, we have:
tan(A + B) = [tan(A) + tan(B)]/[1 - tan(A)tan(B)]
Substitute known values
tan(3π/4 + 2π/3) = [tan(3π/4) + tan(2π/3)]/[1 - tan(3π/4)tan(2π/3)]
Evaluate the expression
tan(3π/4 + 2π/3) = [-1 - √3]/[1 - (-1)(-√3)]
Evaluate the product
tan(3π/4 + 2π/3) = [-1 - √3]/[1 - √3]
Rationalize
[tex]tan(\frac{3\pi}4 + \frac{2\pi}3) = \frac{-1 - \sqrt3}{1 - \sqrt3} * \frac{1 + \sqrt3}{1 + \sqrt3}[/tex]
Evaluate the product
[tex]tan(\frac{3\pi}4 + \frac{2\pi}3) = \frac{-(1 + \sqrt3)^2}{1 - 3}[/tex]
This gives
[tex]tan(\frac{3\pi}4 + \frac{2\pi}3) = \frac{-(1 + 3 + 2\sqrt 3)}{-2}[/tex]
[tex]tan(\frac{3\pi}4 + \frac{2\pi}3) = \frac{-(4 + 2\sqrt 3)}{-2}[/tex]
Divide
[tex]tan(\frac{3\pi}4 + \frac{2\pi}3) = 2 + \sqrt 3[/tex]
So, we have:
tan(17π/12) = 2 + √3
Part B: cos θ using the difference formula.We have:
θ = 17π/12
Express as difference
θ = 9π/4 - 5π/6
The above becomes
cos(17π/12) = cos(9π/4 - 5π/6)
Using the difference formula, we have:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
So, we have
cos(17π/12) = cos(9π/4)cos(5π/6) + sin(9π/4)sin(5π/6)
Evaluate
[tex]cos(\frac{17\pi}{12}) = \frac{\sqrt 2}{2} * - \frac{\sqrt 3}{2} + \frac{\sqrt 2}{2} * \frac 12[/tex]
Evaluate
[tex]cos(\frac{17\pi}{12}) = \frac{\sqrt 2}{2} (- \frac{\sqrt 3}{2} + \frac 12)[/tex]
Evaluate the difference
[tex]cos(\frac{17\pi}{12}) = \frac{\sqrt 2}{2} (\frac{1 - \sqrt 3}{2})[/tex]
Expand
cos(17π/12) = (√2 - √6)/4
Hence, the values of tan θ and cos θ are 2 + √3 and (√2 - √6)/4, respectively

20 hours thank you very mucha pizza with a diameter of 15 inches is cut into 12 equal slices. Carson eats 5 slices of pizza, representing an area of:
Step-by-step explanation:
pizza = circle
the area of a circle is
pi×r²
r = radius (half of diameter), in our case 15/2 = 7.5 in.
the total area of the whole pizza (circle) is
pi×7.5² = 56.25×pi = 176.7145868... in²
it is cut into 12 slices. Carson eats 5 of these 12 slices.
that means he eats 5/12 of the whole area :

Hope it helpsGive the equation of the line in point-
slope form that goes through the point
(-3,7) and is parallel to the line 4x-3y=7
Answer:
[tex]y-7=\frac{4}{3} (x+3)[/tex]
Step-by-step explanation:
Hi there!
We are given the point (-3, 7)
We want to write the equation of the line containing that point, in point slope-form, and that is also parallel to 4x-3y=7
Parallel lines contain the same slope
So first, let's find the slope of 4x-3y=7
To do that, we can convert the line from standard form (ax+by=c) to slope-intercept form (y=mx+b, where m is the slope, and b is the y intercept)
To do that, we need to isolate y on one side
So start by subtracting 4x from both sides
4x-3y=7
-4x -4x
________________
-3y=-4x+7
Divide both sides by -3
y=[tex]\frac{4}{3}x[/tex]- [tex]\frac{7}{3}[/tex]
Since 4/3 is in the place of where m should be, the slope of the line is 4/3
It is also the slope of our new line, which we are trying to find
As stated earlier, we want to write this line in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
This is where the point we were given earlier comes in. We simply need to substitute our values (of the point and the slope) into the formula to find the equation.
First, with the slope; substitute 4/3 as m in the equation
[tex]y-y_1=\frac{4}{3} (x-x_1)[/tex]
Now substitute -3 as [tex]x_1[/tex] in the equation
[tex]y-y_1=\frac{4}{3} (x--3)[/tex]
We can simplify this to:
[tex]y-y_1=\frac{4}{3} (x+3)[/tex]
Now substitute 7 as [tex]y_1[/tex] into the equation
[tex]y-7=\frac{4}{3} (x+3)[/tex]

Plutonium-240 decays according to the function Q(t) = Qoe^-kt
where Q
represents the quantity remaining after t years and k is the decay constant,
0.00011... To the nearest 10 years, how long will it take 36 grams of
plutonium-240 to decay to 12 grams?
Answer:
9990 years
Step-by-step explanation:
The exponential function with given values filled in can be solved for the unknown using logarithms.
__
Q(t) = 12 = 36e^(-0.00011t)
1/3 = e^(-0.00011t) . . . . . . divide by 36
ln(1/3) = -0.00011t . . . . . . take natural logs
t = ln(1/3)/(-0.00011) . . . . divide by the coefficient of t
t ≈ 9990 . . . years
A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups of flour, one cup of sugar, and 2 cups of chocolate chips. how much of each ingredient should be used to make 2 dozen cookies
Answer:
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips
Step-by-step explanation:
3 dozen chocolate chip cookies
3 cups of flour
1 cup of sugar
2 cups of chocolate chips
The recipe is for 3 dozen cookies as stated above.
If you make 2 dozen cookies, then you are making 2/3 of the recipe since 2 is 2/3 of 3.
That means you need 2/3 of all the ingredients.
2/3 × 3 dozen chocolate chip cookies
2/3 × 3 cups of flour
2/3 × 1 cup of sugar
2/3 × 2 cups of chocolate chips
We simplify the amounts to:
2 dozen chocolate chip cookies
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips

Answer:
1/13
Step-by-step explanation:
There are 2 red 5's in a standard 52-card deck ( a red 5 of hearts and a red 5 of diamonds ) and then there are 2 black 6's in a 52-card deck ( a black 6 of clubs and a black 6 of spades )
So in total there are 4 cards that we want out of 52.
So the probability of getting a red five or a black six is 4/52 or 1/13
Answer:
Step-by-step explanation:
This is an or question. You can choose either one; both are possible and the smaller probability add.
Red 5: 2/52
There are 26 red cards. 2 of them are 5s (diamonds / hearts). You are still drawing from a complete pack of 52
Black 6: 2 / 52
There are 26 black cards. 2 of them are 6s (Clubs / spades). You are still drawing from a complete pack of 52
2/52 + 2/52 = 4/52
Divide top and bottom by 4
4/4 // 52 /4
1 / 13

If you are given n=504n=504 and p=0.27p=0.27 for a binomial experiment, use the normal distribution to approximate P(x≤119)P(x≤119). Use continuity correction.
Answer:
[tex]X ≤ P(119) \rightarrow P(X < 119.5)[/tex]
Step-by-step explanation:
Given:
n = 504
p = 0.27
To Approximate:
P(x≤119) usimg normal distribution
Solution:
We know that,
[tex]p+q = 1\\q = 1-p\\q = 1 - 0.27 \\ \fbox{q = 0.73}[/tex]
let's find the mean,
[tex]n \cdot p = 500 \times 0.27 \\ n \cdot p = 135 \\ \mu \: = 135[/tex]
let's calculate standard deviation,
[tex] \sigma = \: \sqrt {n \cdot p\cdot q} \\ \sigma \: = \sqrt{504 \times 0.27 \times 0.73} \\ \sigma \: = 9.96[/tex]
Rewriting the equation using continuity correction,
[tex] P(X ≤ n) \rightarrow P(X < n + 0.5) \\ P(X ≤ 119) \rightarrow P(X < 119 + 0.5) \\ P(X ≤ 119) \rightarrow P(X < 119.5) \\ \fbox{x \: = 119.5}[/tex]
Some more things you must need to know,
standard score is an important part of statistics,
can be derived using formula
[tex]Z = \frac{ x - \mu}{ \sigma} \\ Z = \frac{ 119.5 - 135}{ 9.96} \\ Z= \frac{-15.5}{9.96} \\ \fbox{Z= -1.55}[/tex]
