Answer:

the solution (x,y) for the system of equation  is (-10, -7)

Step-by-step explanation:

y=2/5x-3 and x=-10

y=\frac{2}{5} x-3

Given x=-10

Replace x with -10 in our equation and find out y

y=\frac{2}{5} x-3

y=\frac{2}{5}(-10)-3

y=-4-3=-7

When x=-10 the value of y is -7

So the solution (x,y) for the system of equation  is (-10, -7)

Answer:

The solution is (-10,-7)

Step-by-step explanation:

y=2/5x-3 and x=-10

We know x = -10

Substitute the second equation into the first equation to find y

y = 2/5 (-10) -3

y = -4 -3

y = -7

The solution is (-10,-7)

A small radio transmitter broadcasts in a 63 mile radius. If you drive along a straight line from a city 38 miles north of the t
olchik [2.2K]

Answer:

A signal from the transmitter will be picked up through out the 57.38 mile drive

Step-by-step explanation:

The radius of the transmitter = 63 miles

Therefore, since both the location 38 miles north and the location 43 miles east of the transmitter are within the the radius, the transmission of the transmitter will be received through out the straight line journey

The length of the travel path is given by;

Distance from 38 miles north of the transmitter to distance of 43 miles east of transmitter = \sqrt{38^2+43^2}  = 57.38 \, miles.

Kinesthetic leaner best learn in formation
valina [46]
Metacognition's best definition can be described as an awareness and understanding of one's own thought processes. Answer A is obviously the incorrect choice as it refers to English, not psychology. Answer choice B makes sense as those who understand their own thought processes may be good test takers. Answer choice C is about learning new things which I would say does not necessarily apply to understanding what you know. It is about new knowledge whereas metacognition is about old knowledge. The final answer choice, D, does not apply since metacognition is not a process, but an awareness. I would say that the most applicable answer choice is B.

Hope that helps!

We know that In right angle triangle c^2 = a^2 + b^2.
19^2 = 3^2 + b^2
b = (361 - 9)^1/2 = 18.761663039294
Now for angles
 sin(A) = a/c = 3/19
A = sin{-1}(3/19) = 9.0847202873911
A = 9.0847202873911
sin(B) = b/c = 18.761663039294 / 19
B = sin{-1}(18.761663039294 / 19) = 80.915279712614
B = 80.915279712614
