D. 353
Step-by-step explanation:
just took test
The approximate direction angle of v =<8, -1> is 353°
What is direction angle?For any vector its direction angle is the angle that vector makes with a horizontal line.
Formula to find the direction angle of vector:The direction angle of vector <x , y> is ,
[tex]\theta=tan^{-1}(\frac{y}{x} )[/tex]
For given example,
We have been given a vector v = <8, -1>
Let [tex]\theta[/tex] be the direction angle
x = 8, y = -1
Using the formula of direction angle of vector,
[tex]\Rightarrow \theta=tan^{-1}(\frac{y}{x} )\\\\\Rightarrow \theta=tan^{-1}(\frac{-1}{8} )\\\\\Rightarrow \theta=tan^{-1}(-0.125)\\\\\Rightarrow \theta=-7.12501635\\\\\Rightarrow \theta \approx -7^{\circ}[/tex]
If we measure this angle in anticlockwise direction then the direction angle would be,
[tex]\Rightarrow \theta=360^{\circ}-7^{\circ}\\\\\Rightarrow \theta=353^{\circ}[/tex]
Therefore, the approximate direction angle of v is 353°

Answer:
23/50
Step-by-step explanation:
46% is the same as 46/100 that can be simplified to 23/50
The percentage 46% as a fraction in its simplest form is 23/50.
The given fraction is 46%.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The percentage can be written in fraction by dividing the number by 100.
Here, 46% = 46/100
= 23/50
Therefore, the percentage 46% as a fraction in its simplest form is 23/50.

I need the answers please !
Answer:
m<5 = 133°
m<8 = 47°
Step-by-step explanation:
if <2 = 47°, and <5 is supplementary to <2, that means that together they both have to equal 180°. So, to get the measure of <5, you need to do 180 - 47 to get <5 = 133°.
Now, <5 (133°) is supplementary to <8, so they both have to equal 180° together. So, you must do 180 - 133 to get <8 = 47°. Or, another way to get <8 is to notice that <2 and <8 are alternate interior angles, which means they equal the same amount. So if <2 = 47°, then so does <8.

what is the interest earned on a $30,000 deposit for six months at 1.5% interest compounded continuously
Click on the Pic I sent you with the answer to your question hopefully my answer helps you out I tried my best to solve it for you
The interest earned on a $30,000 deposit for six months at 1.5% interest compounded continuously will be $225.846.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
The continuously compound interest formula is given by
P = P₀[tex]e^{rt}[/tex] where r is the annual interest rate and t is the time period in years.
So,
P₀ = 30000
r = 1.5% = 0.015
t = 6 months = 0.5 year
So,
P = 30000[tex]e^{0.015(0.5)}[/tex]
P = 30000 × 1.007528195
P = $30225.84586
So, interest
I = 30225.84586 - 30000 = $225.8486
Hence " The interest earned on a $30,000 deposit for six months at 1.5% interest compounded continuously will be $225.846".

The drawing below shows 3 parking lots that enclose a shopping mall shaped like a right triangle. If Lot A’s perimeter is 40 miles and Lot B’s perimeter is 24 miles, what is the perimeter of Lot C?
Answer:
40 miles because they are da same size
Step-by-step explanation:
The perimeter of lot C is 46.64 miles
Lot C is a square, hence the perimeter of lot C with a length of each side as a miles is:
Perimeter = 4 * length = 4a
40 = 4a
a = 10 miles
Lot B is a square, hence the perimeter of lot B with a length of each side as b miles is:
Perimeter = 4 * length = 4b
24 = 4b
b = 6 miles
Let c represent the length of lot A,, since a, b, c form a right angle triangle. Using Pythagoras theorem:
c² = a² + b²
c² = 10² + 6²
c² = 136
c = 11.66 miles
Perimeter of lot C = 4 * c = 4 * 11.66 = 46.64 miles
The perimeter of lot C is 46.64 miles
