What is the value of (2/3)^-4 ?
Answer: 81/16
Step-by-step explanation:
When you have a negative exponent, it is equivelant to taking the reciprocal of the exponential and making the exponent positive:
[tex](2/3)^-^4=\frac{1}{(2/3)^4}[/tex]
Distribute the exponent to the base. We are able to do this because the base is composed of a single term. If it were composed of addition and subtraction, you cannot distribute the exponent:
[tex]\frac{1}{(2/3)^4}=\frac{1}{(2^4/3^4)}=\frac{1}{(16/81)}[/tex]
Dividng by a fraction is equivalent to multiplying by the reciprocal:
[tex]\frac{1}{(16/81)}=1\frac{81}{(16)}=\frac{81}{16}[/tex]

The ground speed (G) is given as
.[tex]G=\sqrt{(600\dfrac{\sqrt{3}}{2}+20)^2+(300+40\dfrac{\sqrt{3}}{2}})^2}[/tex]
The correct potion is B.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.
It means the airplane is flying in the opposite direction of the wind.
The component of an airplane will be
[tex]x=-600sin30\\\\x=\dfrac{-600}{2}=-300\\\\y=-600cos30\\\\y=\dfrac{-600 \sqrt{3}}{2}}[/tex]
The component of wind will be
[tex]x=40cos60\\\\x=\dfrac{40}{2}=20\\\\y=40sin45\\\\y=\dfrac{40\sqrt{3}}{2}}[/tex]
Then the ground speed will be

Two spheres have volumes of 8π cm3 and 64π cm3. if the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere? 64π cm2 96π cm2 128π cm2 256π cm2
The surface area of the larger sphere with a volume of 64π cm³ comes to be 16π∛36 cm³.
The volume of the larger sphere = 64π cm³
Suppose the radius of the larger sphere is r
So, 4/3*π*r³ =64π
r³=48
r=2∛6
What is the surface area of a sphere?The surface area of a sphere is 4πr² where r is the radius.
So, the surface area of the larger sphere = 4π(2∛6)²
The surface area of the larger sphere = 16π∛36

Answer: New cost of Barcelona ticket is £164.5
Given that:
the money of is Barcelona ticket = £175
Decrease rate = 6%
Find:
New cost of Barcelona ticket
Computation:
New cost of Barcelona ticket = Cost of Barcelona ticket - [Cost of Barcelona ticket][Decrease rate]
New cost of Barcelona ticket = 175 - [175][6%]
New cost of Barcelona ticket = 175 - 10.5

The angles are in correct order greatest to least is 330°, 5π/3, 7π/6, 2π/3, π/2.
What is a reference angle?A reference angle means the measure of the smallest, positive, acute angle that is formed by the terminal side of the angle. Therefore, positive reference angles possess terminal sides in the first quadrant.
Lets convert all the values into degrees
330° = 330°
π/2 = 180/2 = 90°
5π/3 = 300°
7π/6 = 210°
2π/3 = 120°
Arrange them from greatest to lowest.
330°, 300°, 210°, 120°, 90°
or
330°, 5π/3, 7π/6, 2π/3, π/2

what values make 4s+3=9 true
Answer:
Solve for 's' using inverse operations;
4s + 3 = 9
Get rid of constants first.
By doing this, we subtract 3 from both sides because the inverse operation of addition is subtraction.
-3 -3
4s = 6
Isolate 's' by dividing 4 from both sides because the inverse operation of multiplication is division.
÷ 4 ÷ 4
s = 6/4 which equals 1.5 therefore the value of 's' to make this equation true is 1.5.

Find the interest on the following loan.
$5315 at 5%; loan made on August 10 and due December 23
The interest amount (simple interest ) on the loan amount $5315 at 5% from 10th aug to 23rd dec. of same year is $105.50
How to calculate simple interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
For this case, we're specified that:
Principal amount = $5315Rate of interest = R% = 5% (assumingly annually, and simple interest).Time for which interest was applied: 10th aug to 23rd dec.( of same year assumingly)Converting this time in terms of year, we get:
Aug has 31 days, Sept has 30 days, Oct. has 31 days, Nov has 30 days.
From 10th aug, till its last, there went 22 days.
Whole sept and oct and nov. was spent (30+31+30 = 91 days)
And then there were 22 days of december(23rd day not covered assumingly)
So, total days = 22+22+91 = 145 days.
Assuming averagely 365.25 days in an year, we get the average time for which the interest will be calculated as:
[tex]\dfrac{145}{365.25} \approx 0.397 \: \rm years[/tex]
Thus, we get: the amount of interest as:
[tex]I = \dfrac{P \times R \times T}{100}\\\\I \approx \dfrac{5315 \times 5\times 0.397}{100} \approx 105.50 \: \rm dollars[/tex]
Thus, the interest amount (simple interest ) on the loan amount $5315 at 5% from 10th aug to 23rd dec. of same year is $105.50

This is an example of corresponding angles (corresponding angles are equal). If you search corresponding angles online there are indepth algebraic explanations as to why corresponding angles are equal. In order to be corresponding, they need to be on the same side of the transversal (the line cutting through the 2 parallel lines) and be on the same side of their "parent" line as the other.
