a bicyclist traveled 62 miles in 2 hours.the biker tracked at a constant speed and did not stop for a break.if the biker continues to travel at this rate,which equation can be used to determine y,the total number of miles the biker will travel,in x hours

A.y=62x
B.y=x+62
C.y=31x
D.y=x+31

Answers

Answer 1

Answer:

Step-by-step explanation:

if the bicyclist travels 62 miles in 2 h, he travels 62/2=31 miles per hour

y=nr miles

y=31x

choice C

Answer 2

Answer:

C

Step-by-step explanation:

Divide 62 by 2 to get the unit rate (31 miles per hour)

62/2= 31

X is used to show the number of hours. We are trying to determine the number of miles the biker will travel in x hours. So we would need to multiply 31 and "X" or we could write it as "31x"

Hope this helps!

Step-by-step explanation:

Round $42.58 to the nearest ten dollars to get $40. $40 ÷ 100 = $0.4 so this is one percent. $0.4 × 15 is $6 which is an estimate of 15% of $42.58.

Answer:

-17√2 /26 or -0.9247 to the nearest ten thousandth.

Step-by-step explanation:

The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)

= √13 so sin x = 2/√13 and cos x = 3/√13

sin2x = 2sinxcos

= 2* 2/√13 * 3/√13

= 12/13.

cos2x = cos^2x - sin^2x

= 9/13 - 4/13

= 5/13.

sin(2x + 5π/4)

= sin2x cos5π/4 + cos2x sin5π/4

= 12/13 * -1/√2 + 5/13 * -1/√2

= -12 / 13√2  - 5 / 13√2

= -17/13√2

= -17√2 /26.

f(x) = -3(x + 7)(x + 4),

Remember that to solve for the x-intercepts we equate y to 0,

-3(x + 7)(x + 4) = 0

Using the zero product property,

x + 7 = 0, x + 4 = 0

x = - 7, x = -4

x -intercepts: (- 7, 0) & (- 4, 0)
