prisoha [69]

Answer:

B

Step-by-step explanation:

lets start off by looking at point A (1,1)

4 units to the right is along the x-axis, so the x-coordinate would be 5 (1 + 4)

2 units up is on the y-axis, so the y-coordinate would be 3 (1 + 2)

A is now (5,3). we can eliminate choices A, C, and D as they each have negative numbers in them, and we are moving in the positive direction, not the negative.

the answer is B

dolphi86 [110]

Answer:

1974.6 feets

Step-by-step explanation:

The plane's altitude is : h + 100 feets

To obtain h, according to the attached picture ;

We can use trigonometry :

Tan θ = opposite / Adjacent

Opposite = h ; adjacent = 3000 feets

Tan 32° = h / 3000

h = 3000 * 0.6248693

h = 1874.6080

Plane's altitude :

h + 100 feets

(1874.6080 + 100) feets

= 1974.6 feets

Advocard [28]

Answer:

Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Step-by-step explanation:

Let Wanda and Dave catch each other when x be the time after Dave starts walking and y be the distance covered by them

It is given that Wanda started walking along a path 27 seconds before Dave and the constant speed of Wanda is 3 feet per second.

speed=\frac{distance}{time}

3=\frac{y}{x+27}

y=3(x+27)

 y=3x+81                          .... (1)

The constant speed of Dave is 4.5 feet per second.

4.5=\frac{y}{x}

y=4.5x                                .... (2)

Equate equation (1) and (2).

3x+81=4.5x

81=1.5x

Divide both sides by 1.5.

\frac{81}{1.5}=x

54=x

Therefore, Wanda and Dave will catch each other in 54 seconds after Dave starts walking.
