What is the area of a triangle with vertices at (−4, 1) , (−7, 5) , and (0, 1) ?

Mekhanik [1.2K]

Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

Find the area of the shaded triangle

Ivanshal [37]

Answer:

18 square units

Step-by-step explanation:

15. Find the force on an electron crossing a uniform magnetic field of intensity 0.5 T WILII

EleoNora [17]

Answer:

F = 8.48 x $10^{-18}$ N

Step-by-step explanation:

The force on an electron in a magnetic field can be determined by;

F = qvB Sin θ

where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.

Thus,

q = -1.6 x $10^{-19}$ C

v = 106 m/s

B = 0.5 T

θ = $90^{o}$

So that,

F = 1.6 x $10^{-19}$ x 106 x 0.5

= 8.48 x $10^{-18}$ N

The force on the electron crossing the uniform magnetic field is 8.48 x $10^{-18}$ N.

Lane is making accessories for the soccer team. He uses 759.46 inches of fabric on headbands for 44 players and 2 coaches. He al

madam [21]

Answer:

Fabric used by each each player for headband is 16.51 inches and fabric used for wristband is 1.99 inches

Step-by-step explanation:

In first case it is given that there are players and 2 coaches

So total number = 44+2 = 46

It is given that 759.46 inches of fabric is used on headbands for 44 players and 2 coaches

So fabric used by each player $=\frac{759.46}{46}=16.51inches$

Now in second 87.64 inches fabric is used for 44 players

So fabric used by each players $=\frac{387.64}{44}=1.99inches$

So fabric used by wristband is 1.99 inches
