Answer:
87, if it were 45 degrees, it would be 90, closest to 90 is 87
Answer:
87 feet
Step-by-step explanation:
We have an angle that's 44 degrees and we know that Susan is 90 feet from the base of the tree. We need to know the height of the tree, which is the value opposite from the angle we know.
Use tangent to find height.
tan (44) = x / 90 then multiply both sides by 90
x = tan (44) * 90 evaluate tan(44) and substitute into the equation
x = 86.911
round to nearest whole foot: 87 feet

Solve the equation 18y-6y+22=11(y-2)+y
Answer:
the answer its 44=0
Step-by-step explanation:
18y-6y+22=11(y-2)+y1
We move all terms to the left:
18y-6y+22-(11(y-2)+y1)=0
We add all the numbers together, and all the variables
12y-(11(y-2)+y1)+22=0
We calculate terms in parentheses: -(11(y-2)+y1), so:
11(y-2)+y1
We add all the numbers together, and all the variables
y+11(y-2)
We multiply parentheses
y+11y-22
We add all the numbers together, and all the variables
12y-22
Back to the equation:
-(12y-22)
We get rid of parentheses
12y-12y+22+22=0
We add all the numbers together, and all the variables
44=0

Answer:
[tex]\frac{27}{64}[/tex]
Step-by-step explanation:
[tex]\left( \frac{3}{4}^3 \right) = \frac{3^3}{4^3} = \frac{3\cdot 3\cdot 3}{4 \cdot 4 \cdot 4} = \frac{27}{64}[/tex]
What is the modulus and argument after (StartRoot 3 EndRoot) (cosine (StartFraction pi Over 18 EndFraction) + I sine (StartFraction pi Over 18 EndFraction) ) gets raised to the 6thpower?
modulus = StartRoot 3 EndRoot ; argument = StartFraction pi Over 18 EndFraction
modulus = StartRoot 18 EndRoot; argument = StartFraction pi Over 3 EndFraction
modulus = 27; argument = StartFraction pi Over 3 EndFraction
modulus = 729; argument = StartFraction pi Over 18 EndFraction
Answer:
[tex]|z| = 27[/tex] -- Modulus
[tex]\theta = \frac{\pi}{3}[/tex] --- Argument
Step-by-step explanation:
Given
[tex]((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]
Required
Determine the modulus and the argument
We have that:
[tex]z = ((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]
Expand:
[tex]z = (\sqrt 3)^6(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]
[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]
A complex equation can be expressed as:
[tex]z = |z| e^{i\theta}[/tex]
Where
[tex]|z| = modulus[/tex]
[tex]\theta = argument[/tex]
Where
[tex]e^{i\theta} = (cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})[/tex]
So:
[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex] becomes
[tex]z = 27(e^{i\frac{\pi}{18}})^6[/tex]
By comparison:
[tex]e^{i\theta} = (e^{i\frac{\pi}{18}})^6[/tex]
This gives:
[tex]{i\theta} = i\frac{\pi}{18}}*6[/tex]
[tex]{i\theta} = i\frac{6\pi}{18}}[/tex]
[tex]{i\theta} = i\frac{\pi}{3}}[/tex]
Divide through by i
[tex]\theta = \frac{\pi}{3}[/tex]
Hence, the modulus, z is:
[tex]|z| = 27[/tex]
And the argument [tex]\theta[/tex] is
[tex]\theta = \frac{\pi}{3}[/tex]

Find the measure of the angle shown by the arrow(in radians)
Answer:
-7π/3 or -420 degrees
Step-by-step explanation:
So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.
The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.
π/2 - π/6
3π/6 - π/6 = 2π/6
π/3
Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3
A chemist wants to mix a 10% acid solution with a 26% acid solution to obtain 16 liters of a 14% acid solution. How much of the 26% solution should she use?
Answer:
The 26% solution should she use is explained below in detailed explanation.
Step-by-step explanation:
Assumed there be 10 percent of x liters of acid solution
Assumed there be 26 percent of y liters of acid solution
provided Information
A chemist needed to combine a 10 percent acid solution with a 26 percent acid solution to obtain 16 liters of a 14 percent acid solution
So, ( 10 / 100 )*x + ( 26 / 100 )*y = ( 14 / 100 )*16
=> 0.1*x + 0.26*y = 0.14*16
=> 0.1*x + 0.26*y = 2.24 ....................... eq 1
x + y = 16 ......................... eq 2
Multiply ( 0.1 ) in both side in eq 2
=> 0.1*x + 0.1*y = 0.1*16
=> 0.1*x + 0.1*y = 1.6 ......................... eq 3
Subtract eq 3 from eq 1
0.1*x - 0.1*x + 0.26*y - 0.1*y = 2.24 - 1.6
=> 0.16*y = 0.64
=> x = 0.64 / 0.16
=> y = 4
So, 4 liters of 26% solution she should utilized

Find the derivation of the following functions with they corresponding variables
Answer:
d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))
Step-by-step explanation:
To find the derivative of f(t), we have to find the derivative of each component of the function to make it easier.
d(8/(t^7))/dt = d(8xt^-7)/dt = –7 x 8 x t^-8 = –56t^-8 = -56/(t^8)
d(5/(t^(1/6)))/dt = –(1/6) x 5 x t^(-7/6) = –(5/6)/t^(7/6)
d(3t^4)/dt = 4 x 3 x t^3 = 12t^3
d(t²)/dt = 2t
d(t^⅓)/dt = ⅓t^(-2/3) = (1/3)t^(2/3))
d(12)/dt = 0.
Therefore,
d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

the bag of letter tiles include 15 vowels and 25 consonants. What is the probability of selecting two vowels one after another NEED HELP ASAP
Answer: 0.1346
Step-by-step explanation:
Number of vowels = 5 vowels
Number of consonants = 25
For us to calculate the probability of selecting two vowels one after another, we have to select the first vowels which will give a probability of 5/40, then we select the second vowel which will be 4/24 since there'll be 4 vowels left 39 alpahabets.
Therefore, probability of selecting two vowels one after another will be:
= 15/40 × 14/39
= 3/8 × 14/39
= 0.1346
