46 yards was travelled north while 172 yards was travelled west.

Trigonometric ratios shows the relationship between the sides of a triangle and its angles.

For the question, the distance travelled north and distance travelled west can be determined using trigonometric ratio.

sin(15) = distance travelled north / 178

Distance travelled north = 46 yards

Also:

cos(15) = distance travelled west / 178

Distance travelled west = 172 yards

Hence, 46 yards was travelled north while 172 yards was travelled west.

Answer:

x = 4

x = 10

Step-by-step explanation:

x^2 -14x + 40 = 0 ----> factor form

(x - 10)(x - 4) = 0 ---> separate equations

x - 10 = 0 ---> add 10 on both sides

x = 10

x - 4 = 0 ---> add 4 on both sides

x = 4

Answer:

small x= 4

large x= 10

Step-by-step explanation:

hello there!

x^2-14x+40=0

x^2-(10+4)x+40=0

x^2-10x-4x+40=0

pick out the common one!

x(x-10)-4(x-10)=0

(x-10)(x-4)=0

now;

x-10=0

x=10(which is large x)

again:

x-4=0

x=4( which is small x)

Answer:

x = (-1 ±[tex]\sqrt{145}[/tex] )/8

Step-by-step explanation:

Quadratic formula: x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex] )/(2a)  

4x² + x - 9 = 0 ; General form of a quadratic is ax² +bx + c = 0

So a = 4, b = 1, and c = -9

x = -1 ±[tex]\sqrt{1^{2}-4(4)(-9)}[/tex] / 2(4)

x = -1 ± [tex]\sqrt{1 + 144}[/tex] /8

x = -1 ±[tex]\sqrt{145}[/tex] /8

x = (-1 + [tex]\sqrt{145}[/tex])/8    or x = (-1 - [tex]\sqrt{145}[/tex])/8

======================================================

Explanation:

Let's add up the positive values only for now. So we get 172+48 = 220 which represents all the money coming into the account.

Do the same for the negative values. We'll simply add the positive versions of each (ignore the negative signs). So -17 and -40 can be thought of as 17 and 40, which add to 17+40 = 57. Ultimately this result is negative leading us to -57.

In other words, -17 + (-40) = -57

So you can see that adding negatives follows the same rule as positives. The only change is that everything turns negative.

The notation -57 means that 57 dollars is going out in terms of expenses, purchases, withdrawals, fees, etc.

---------------------

To summarize everything so far:

We subtract those results to find the final balance

balance = moneyIn - moneyOut = 220-57 = 163 dollars

We subtract positive versions of each number.

Answer:

6 1/2

Step-by-step explanation:

change 1 4/9 into a improper fraction, which is 13/9, and when dividing fractions flip the second number upside down then multiply. 13/9 times -2/9 is -117/18. simplify, which is 13/2, which is also equal to 6 1/2. hope this helped

Answer:

Sasha's car moves 13 meters faster than Frank's car

Step-by-step explanation:

I took Sasha's 875 meters and divided it by 7minutes and got 125

Then, I took Frank's 1232 meters and divided it by 11 minutes and got 112

Finally, I subtracted 125 by 112 and got 13 meters

Answer:

125 × 11 = 1375

1375 > 1232

Sashas car goes faster then Frank's

Sashas car goes 143 meters faster then Franks

Answer:

11

Step-by-step explanation:

Answer:

f(-2) = 11

Step-by-step explanation:

Given the function, f(x) = -3x + 5:

We can evaluate f(-2) by substituting -2 as the input (or x-value) for the function:

f(-2) = -3x + 5

f(-2) = -3(-2) + 5

f(-2) = 6 + 5

f(-2) = 11

Therefore, f(-2) = 11.

first, make the line into slope-intercept form.

-3x - 5y = 1

-5y = 3x + 1

y = -3/5x - 1/5

a line parallell to this line has to have the same slope, so it could be but doesn't have to be y = -3/5x - 1

a line perpendicular to y = -3/5x - 1/5 has to have the opposite slope of it.

so, y = 5/3x +1

Your answer is acute triangle

Answer:

see explanation

Step-by-step explanation:

Using identities

sec²x = tan²x + 1

cosec²x = cot²x + 1

cos²x = [tex]\frac{1}{cos^2x}[/tex]

(1)

sin²θ + [tex]\frac{1}{sec^20}[/tex]

= sin²θ + cos²θ = 1

(2)

9sec²θ - 9tan²θ

= 9sec²θ - 9(sec²θ - 1)

= 9sec²θ - 9sec²θ + 9

= 9

(3)

- 8cot²A + 8cosec²A

= - 8cot²A + 8(cot²A + 1)

= - 8cot²A + 8cot²A + 8

= 8

(4)

- 10cosec²β + 10cot²β

= - 10(cot²β + 1) + 10cot²β

= - 10cot²β - 10 + 10cot²β

= - 10
