Traveling with the current a certain boat went 16km/h. Against the same current it only went 6km/h. Find the current and the spe
Aloiza [94]

Answer:

Step-by-step explanation:

b and c are the speeds of the boat in stool water, and current, respectively.

Going with the current, the boat travels b+c=16 km/h.

Going against the current, the boat travels b-c=6 km/h

add the equations together

b+c = 16

b-c = 6

—————

2b = 22

b = 11

c = 16-b = 5

Passing through (-5,4) with slop -3 ?
PSYCHO15rus [73]

Hey there! :)

Answer:

y = -3x - 11

Step-by-step explanation:

Use the formula y = mx + b to write an equation, where:

y = y-coordinate of point

x = x-coordinate of point

m = the slope

Plug in the known coordinates and slope:

4 = -3(-5) + b

Simplify:

4 = 15 + b

4 - 15 = b

-11 = b

Rewrite the equation:

y = -3x - 11

The product of multiplication of 16 × 9 gives us; 144

<h3>Multiplication</h3>

We want to find the product of 16 and 9.

Now, to solve this we can use a little illustration for example if I have a basket of oranges and I want to given 9 people each 16 oranges, it means that the total number of oranges I will give out is; 16 × 9 = 144

Thus, our question answer is 16 × 9 = 144

Answer:

11. Equation of hyperbola having  vertices at (0, ±6) and foci at (0, ±9).

is given by \frac{y^2}{a^2}- \frac{x^2}{b^2}=1

also b²= c²-a²

 b²=81-36

b²=45

So, Equation becomes , \frac{y^2}{36}- \frac{x^2}{45}=1

Option (D) is correct.

12.Vertices (0,  ± 4), Asymptotes = ±1/4.x

equation of asymptote is given by, x = \pm y \frac{b}{a}

\frac{4}{b}=\frac{1}{4}

So a=4 and b=16,

So , equation becomes \frac{y^2}{16}- \frac{x^2}{256}=1

Option (B) is correct.

13.  x= t-3, and y = t²+ 5

Replace t by x+3, we get

y= (x+3)² +5

y=x²+ 6x +14

Option (A) is correct.

14. Polar coordinates is given by (r,∅)

Polar coordinates of point is (3, 2π/3)

So, r =3, ∅ =2π/3

x= r cos∅ and y = r sin∅

x=3 Cos (2π/3) and y= 3 Sin (2π/3)

x= -3/2 and y=3√3/2

Option (A) is correct.

14. Polar coordinate is given by (r,∅)

Here , r=1, and ∅ = -π/6

x= r Cos ∅ and y =r Sin∅

x= 1 Cos (-π/6) and  y= 1 Sin (-π/6)

x =√3/2 and y =1/2

Option (B) which is B) (1, negative pi divided by 6 + 2nπ) or (-1, negative pi divided by 6 + 2nπ) is correct.

16. Two pairs of polar coordinates for the point (4, 4) with 0° ≤ θ < 360°.

is  option (B) which is B) (4 square root 2 , 45°), (-4 square root 2 , 225°).

17. A circular graph with inner loop on the left of a limacon curve is given by

r = a + b Cos∅.

In this case a> b.

So , Option (D) r = 4 + cos θ as well as (A) r = 3 + 2 cos θ looks correct.

18. Equation of limacon curve is given by r = -2 + 3 cos θ, here , a<b

So it is symmetric about y-axis only.Option (B) is correct.
