Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)

what are the coordinates of vertices N'G'M'​

Triangle NGM is reflected across the x-axis, and is dilated by a factor of [tex]2 \frac{1}{2} [/tex]what

Answers

The coordinates of vertices N'G'M'​ are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = \(2\frac{1}{2}\)

= 2.5

The reflection of point (x, y) across the x-axis is (x, -y).

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)

Now, with scale factor 2.5, we get

(-4, -6)→2.5(-4, -6)→N'(-10, -15)

(-6, -2)→2.5(-6, -2)→M'(-15, -5)

(-2, -4)→2.5(-2, -4)→G'(-5, -10)

Therefore, the coordinates of vertices N'G'M'​ are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

when x increases from a to a +2, y increases by a factor of 1/4

Answers

Answer:

y=7* (0.5)^x

Step-by-step explanation:

We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.

i.e. when x=a and x'=a+2.

then y/y=0.25 where y' is the function after putting x' to the old function.

Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.

Answers

It would be A and C.

ANSWER : A AND D.

Step-by-step explanation:

the water current would be 2 mph and the canoe is 4 mph

See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.

The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.

The answers should be A and D.

To graph the inequality x > -3, draw an open circle on -3 and shade to the left true or false.

Answers

Answer:

False

Step-by-step explanation:

The first part of the statement is correct with it saying to have an open circle on -3, but the shading should go on the right because x is bigger than -3. When you picture a number line, the numbers on the right of -3 are bigger than the numbers on the left.

The statement " To graph the inequality x > -3, draw an open circle on -3 and shade to the left" is wrong.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The first part of the statement is correct, as it states that an open circle should be placed on -3, but the shading should be placed on the right because x is greater than -3. On a number line, the numbers to the right of -3 are larger than the numbers to the left.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
