Answer:
(c) (-6, 1)
Step-by-step explanation:
The answer choices suggest the missing point is in the 2nd quadrant and below the given point in that quadrant. (All the x-values are negative, and the y-values are less than 6.)
There are at least a couple of ways you can find this point. We choose to consider the points of the opposite side: the two points in the first quadrant.
The bottom of these is 2 units left of the top one, and 5 units below it. (You can determine this by counting grid squares or by comparing coordinates.)
So, a point 2 left and 5 below the upper left point (-4, 6) will have coordinates ...
(-4, 6) +(-2, -5) = (-4-2, 6-5) = (-6, 1) . . . . the missing point
_____
Alternative solution
The midpoints of the diagonals of a parallelogram are the same point, so the sum of coordinates at the ends of each diagonal will be the same. This means you can find the missing point (D) using A+C-B = D, where A, B, C are the given points labeled clockwise from upper left.
D = A +C -B = (-4, 6) +(1, 2) -(3, 7) = (-4+1-3, 6+2-7)
D = (-6, 1)
__
Additional comment
This relation between point coordinates is true regardless of how the given points are labeled. A different labeling will give a different point D, meaning 3 points can be the vertices of 3 different parallelograms. That is why we start this answer with a comment regarding where we expect the 4th point to be.

A man covers a distance of 150m in 1.5mins. Find the average speed in km per hour
Answers
Answer:
6 Km / hour
Step-by-step explanation:
Convert distance to Km ( 1 Km = 1000 m )
150 m = 150 ÷ 1000 = 0.15 Km
Convert 1.5 mins to hours ( 1 hour = 60 minutes )
1.5 = 1.5 ÷ 60 = 0.025 hours
average speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{0.15}{0.025}[/tex] = 6 Km / hour
The average speed in km per hour is 6 kilometers per hour
How to determine the average speed?The given parameters are:
Distance = 150 mTime = 1.5 minsConvert meters to kilometers
Distance = 150/1000 km
Distance = 0.15 km
Convert minutes to hours
Time = 1.5/60 hour
Time = 0.025 hour
The average speed is then calculated as:
Speed = Distance/Time
This gives
Speed = 0.15 km/0.025 hour
Evaluate
Speed = 6 kilometers per hour
Hence, the average speed in km per hour is 6 kilometers per hour

4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)
Answers
9514 1404 393
Answer:
f(x) = 4·3^x
Step-by-step explanation:
We assume the function will be of the form ...
f(x) = a·b^x
Substituting the given values, we can find 'a' and 'b'.
4/9 = a·b^(-2)
108 = a·b^3
Dividing the second equation by the first gives ...
108/(4/9) = b^(3 -(-2))
243 = b^5
b = 3 . . . . . . 5th root
Using the second equation, we can find 'a':
108 = a·3^3 = 27a
a = 108/27 = 4
The formula for the exponential function is ...
f(x) = 4·3^x

Write 1/ 5 √ 7 in index form
Answers
Your answer is long see it check correctly.
The index form of the fraction [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] where the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].
Given data:
In index form, the expression [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] , where the base is 7 and the exponent is -1/5. This means that we are taking the reciprocal of the fifth root of 7. The exponent of -1/5 indicates that we are essentially finding the inverse of the fifth root of 7.
When dealing with fractional exponents, the denominator of the fraction becomes the root, and the numerator becomes the power to which the base is raised. In this case, the base is 7, the denominator is 5, and the numerator is -1. So, [tex]7^{(\frac{-1}{5})}[/tex] represents the reciprocal of the fifth root of 7, which can also be expressed as the fifth root of 7 raised to the power of -1.
Hence, the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].
