Answer:

10 minutes

Step-by-step explanation:

If it takes them 5 minutes to fill four jugs, then they have 8 left. Since 8/4=2, and 2*5=10, it will take them 10 minutes to fill the rest of the jugs.

Hopefully this helps, let me know if you have more questions!

The point ( - 14,12) is on the graph of y = f(x). Find the corresponding point on the graph of y= qe), where gex) = arcus.
liubo4ka [24]

Answer:

(-14,4)

Step-by-step explanation:

Given

(-14,12)   \to    y =f(x)

g(x) = \frac{1}{3}f(x)

Required

The corresponding point on y = g(x)

(-14,12)   \to    y =f(x) means:

12 = f(-14)

or

f(-14)=12

g(x) = \frac{1}{3}f(x) is calculated

g(-14) = \frac{1}{3} * f(-14)

g(-14) = \frac{1}{3} * 12

g(-14) = 4

So, the corresponding point on y = g(x) is: (-14,4)

Find the primary solution of cosθ=−0.3<br><br> ⁡
Agata [3.3K]

The solution of cos θ = −0.3 is θ = 107.45760312 degrees

<em><u>Solution:</u></em>

Given that we have to find the primary solution of cos \theta = -0.3

To solve this equation, you must find the unknown (theta)

cos \theta = -0.3

Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta

\theta = arccos (-0.3)

We know that arccos (-0.3) = 107.45760312 degrees

[ If you reference a unit circle or use a calculator ]

\theta = 107.45760312^{\circ}

Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees

Principle $1950 rate 4 1/2% time 9
Gennadij [26K]

Answer:

Interest = \boxed{\$ 789.75}

Explanation:

Interest [I] = principle × rate × time [prt]

______________________________

x% = x/100

a b/c = a + (b/c) = (ac + b) / c

______________________

I = prt

I = ($1,950)(4 ½%)(9)

I = ($1,950)(0.045)(9)

I = ($87.75)(9)

I = ($789.75)

I = $789.75
