If A = (4,-5) and B = (7.-9), what is the length of AB?

Nookie1986 [14]

Answer:

5

Step-by-step explanation:

We can figure out the length of AB by using the distance formula.

$D = \sqrt{(7-4)^{2} + (-9-(-5))^{2} }\\ D = \sqrt{(3)^{2} + (-4)^{2} }\\D = \sqrt{9 + 16}\\D = \sqrt{25}\\D=5$

So the distance is 5

What is the height of a projectile in 4 seconds if its initial height is 125 ft and it has a velocity of 300 ft per second? 972

andre [41]

Answer:

B. 1069 feet

Step-by-step explanation:

$d=v_ot+\dfrac{1}{2}at^2 \\\\d=(300)(4)+\dfrac{1}{2}(-32)(4)^2 \\\\d=1200-256=944$

Adding the initial 125 feet to this, you get a total height of 1069 feet. Hope this helps!

Find the area A of the polygon with the given vertices.

Natalija [7]

Answer:

A = 35 square units

Step-by-step explanation:

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Length of the segment between A(2, 2) and B(9, 2) = $\sqrt{(9-2)^2+(2-2)^2}$

= 7 units

Length of the segment between B(9, 2) and C(9, -3) = $\sqrt{(9-9)^2+(2+3)^2}$

= 5 units

Length of the segment between C(9, -3) and D(2, -3) = $\sqrt{(9-2)^2+(-3+3)^2}$

= 7 units

Length of the segment between A(2, 2) and D(2, -3) = $\sqrt{(2-2)^2+(2+3)^2}$

= 5 units

Therefore, given polygon is a rectangle.

Area of the rectangle = length × width

= 7 × 5

= 35 square units

Kendall just became a personal trainer and is finalizing her pricing plans. One plan is to charge $37 for the initial consultati

Veronika [31]

Answer:

The 2 Plan will have same cost of $2149 after 64 sessions.

Step-by-step explanation:

Given;

Let the Two plan be Plan A and Plan B.

Also let the number of session be $x$

According to given detail

Plan A = $\$37+33x$

Plan B = $\$101+32x$

We need to find the value of when both are equal.

Plan A = Plan B

$\$37+33x$ = $\$101+32x$

Solving above equation we get;

$33x-32x=101-37\\x=64$

Number of session are 64.

Cost after 64 session will be,

Plan A = $\$37+\$33x=\$37+\$33\times 64 = \$37+\$2112 = \$2149$

Plan B = $\$101+\$32x=\$101+\$32\times 64 = \$101+\$2048 = \$2149$

Hence The 2 Plan will have same cost of $2149 after 64 sessions.
