I need blank 1 and blank 2

Mathematics
1 answer:
lord [1]3 years ago
8 0

Answer:

Blank 1: 40

Blank 2: 10

Step-by-step explanation:

You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.

y+x=50

y-x=30

Adding these two equations together, you get:

2y=80

y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.

40-x=30

x=10

Hope this helps!

Determine the currents in the picture
Elenna [48]

Answer:

The value of currents are I_1=0A, I_2=1A and I_3=1A.

Step-by-step explanation:


The Ohm's law states that

V=IR

it is given that the V₁=3V and V₂=4V.

In a parallel circuit:

  • Voltage is same in each component
  • Sum of the currents equals to the total current that flows.

I_2=I_1+I_3                   .... (1)

Equation for first loop is,

V_1=4I_1+3I_2

3=4I_1+3I_2              ..... (2)

Equation for second loop is,

V_2=1I_3+3I_2

4=1I_3+3I_2             ..... (3)

On solving (1), (2) and (3) we get

I_1=0


I_2=1

I_3=1

Therefore the value of currents are I_1=0A, I_2=1A and I_3=1A.

The first three terms of a sequence are given. Round to the nearest thousandth (if
Mumz [18]

Answer:

\frac{3}{16}

Step-by-step explanation:

The common ratio is \frac{1}{2}

24, 12, 6, 3, \frac{3}{2}, \frac{3}{4}, \frac{3}{8}, \frac{3}{16}

so divide each term by 2

What is the constant of the variation for the inverse variation?
Alisiya [41]

Answer:

2nd possible answer is the correct one; the const. of var. is 1/3.

Step-by-step explanation:

xy = 1/3 can be rewritten in inverse variation format:  Divide both sides by x to isolate y.  Then y = (1/3)(1/x).  The constant of (inverse) variation is 1/3.
