Answer:

The average speed of the boat is 20 km/hr.

Step-by-step explanation:

Given : A boat that moves 15.0 km across a lake in 45 min.

To find : What was the average speed in km/h ?

Solution :

The distance a boat covered is 15 km.

The time taken by boat to cross a lake is 45 minutes.

Convert minute into hour,

1 hour = 60 minute

1 minute = \frac{1}{60} hour

45 minute = \frac{45}{60} hour

45 minute = 0.75 hour

The speed of the boat is given by,

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

\text{Speed}=\frac{15}{0.75}

\text{Speed}=20

The average speed of the boat is 20 km/hr.

Find the vertical asymptote(s) of f of x equals quantity 4 x squared plus 3x plus 6 end quantity over quantity x squared minus 3
siniylev [52]

The vertical asympototes of f(x) are  at x = -6 and x = 6

Step-by-step explanation:

To find the vertical asymptote(s) of a rational function,

  • Equate the denominator by 0
  • Solve it for x
  • If x = a, then the vertical asymptote is at x = a

∵ f(x)=\frac{4x^{2}+3x+6}{x^{2}-36}

- Equate the denominator x² - 36 by 0

∵ x² - 36 = 0

- Add 36 to both sides

∴ x² = 36

- Take √ for both sides

∴ x = ± 6

∴ There are vertical asymptotes at x = -6 and x = 6

The vertical asympototes of f(x) are  at x = -6 and x = 6

Find the measure of angle A
blagie [28]

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

m\angle A = (x +53)\degree \\\\m\angle A = (-10 +53)\degree \\\\m\angle A = 43\degree \\\\

ILL GIVE BRAINLIEST IF ITS RIGHT
Vesna [10]

Answer: 6

Step-by-step explanation:

Slope is found by doing:

\frac{y_1 - y}{x_1 - x}

(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)

Let us say that (x1,y1) is (3,18)

And (x,y) is (5,30)

\frac{18 - 30}{3 - 5} = \frac{-12}{-2} = 6
