Answer:

Step-by-step explanation:

To calculate the distance d use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(3, 1) and (x₂, y₂ ) = B(5, 3)

AB = $\sqrt{(5-3)^2+(3-1)^2}$

= $\sqrt{2^2+2^2}$

= $\sqrt{4+4}$

= $\sqrt{8}$ = $\sqrt{4(2)}$ = 2 $\sqrt{2}$ → A

Ludmilka [50]

Answer:

I think the answer to your question is y=15x+75

Step-by-step explanation:

To become a member you automatically have to pay $75. $75 is your y-intercept because before you work at the gym you have to pay $75. The $15 would be your x or your slope because each month you would have to pay 15 dollars. So the slope intercept form would be y=15x+75. I hope that helps.

Answer: D It is moving in a different direction as the kayak because it slowed Jaime down.

Step-by-step explanation:

Jaime can paddle her kayak at an average rate of 6 miles per hour in still water.

Distance = speed × time

After 2 hours of paddling north in a river, she traveled 8 miles. This distance covered was supposed to be

6 × 2 = 12 miles

Therefore, the following is true about the direction of the current in the river:

D It is moving in a different direction as the kayak because it slowed Jaime down.

In the diagram below, if the measure of < C = 45 °, and side AC = 10, then side BC = _____.

Softa [21]

Solution:

Given:

Using the trigonometric ratio of cosine,

$\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\ cos45=\frac{BC}{10} \\ BC=10\times cos\text{ 45} \\ BC=10\times\frac{\sqrt{2}}{2} \\ BC=5\sqrt{2} \end{gathered}$

Therefore, OPTION A is correct.
