Which represents an exterior angle of triangle EGF?
O ZMEG
O ZNEG
O ZPEQ
O ZRFS

Answers

Answer:

The correct answer is:

ZNEG/∠NEG

Step-by-step explanation:

An exterior angle is one outside the triangle that is formed by extending two of the sides of the triangle. Angle NEG is formed by extending EG and EF; this makes it an exterior angle.

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population of the fish doubles every year.

Use x to represent the number of years and y to represent the population of the fish.

Enter an equation that represents this scenario in the box.

PS: The answer is either y=500(2)^x or f(x)=500(2^x)
I'm not sure which one is correct.

Answer:

A. n = 1/63

B. k = 13/3

C. g = 5

D. w = 21/17

Step-by-step explanation:

A. 9n = 15/7 - 2

9n = 15-14/7

9n = 1/7

n = 1/7 ÷ 9

= 1/7 × 1/9

n = 1/63

B. 1/3 = k - 4

1/3 + 4 = k

1+12/3 = k

13 /3 = k

k = 13/3

C. g - 2/5g = 3

5g-2g/5 = 3

3/5g = 3

g = 3 ÷ 3/5

= 3 × 5/3

= 15/3

g = 5

D. 3/7w + 2w = 3

3w+14w/7 = 3

17/7w = 3

w = 3 ÷ 17/7

= 3 × 7/17

= 21/17

w = 21/17

1) As you know, the area of a square is A = x , where for this problem, A is area in feet and x is the length of a side, in feet. If the length of a side is changing at a rate of 6 feet/minute when the length of a side is 4 feet, at what rate is the area changing?

Answers

The answer is 2 feet

what is the value of n

Answers

Answer:

n=5

Step-by-step explanation:

take 29 add to 56 then divided by 17

Answer:

Step-by-step explanation:

56 = 17n - 29

-17n = -29 - 56 [remember: when u transfer a positive number it becomes negative and when u transfer a negative number it becomes positive]

-17n = -85

n = -85/-17

n = 5

hope u understood^^

Write a function rule for the area of a rectangle whose length is 6 ft more than its width. What is the area of the rectangle when its width is 7 ft? Write a function for the area A of the rectangle using the independent variable-width W.

Answers

The expression for the area in terms of the width is:
A
=
w
2
+
7
w
When
w
=
12
, the area is
228
units.
Explanation:
We know that the formula for the area of a rectangle is:
Area = length x width
A
=
l
w
In this specific case, though, we are told that the length is
7
units greater than the width:
l
=
w
+
7
We can substitute this value for
l
into our area formula, and then there will be only one variable on the right-hand side:
A
=
l
w
=
(
w
+
7
)
w
=
w
2
+
7
w
This expression is the answer to the final sentence in the question, asking us to write an expression for
A
in terms only of
w
.
Now we can use our expression to find the area in the situation where
w
=
12
:
A
=
w
2
+
7
w
=
12

b^2 = 147 (square root)

Function g can be thought of as a scaled version of f(x)=x^2

Answers

Answer:

g(x)=2x^2

Step-by-step explanation:

If you look at (1,1) for the blue function then (2,2) for g(x), you can kind of see that it is scaled by 2 (meaning its just twice as big). In another case you can see the blue function passing through (2,4), which matches with the point given to you for g(x), (4,8), which is twice as big.

The function of g(x) = 2x² can be thought of as a scaled version of f(x) = x².

What is Parabola?

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.

parabola, open curve, a conic segment produced via the intersection of a proper circular cone and a plane parallel to an element of the cone.

To determine the function of g(x) can be thought of as a scaled version of f(x) = x²

When considering (1,1) for the blue function and (2,2) for g (x),

Its two-scale scaling can be seen in some parts implying that it is simply twice as large.

The blue function is visible in another instance as it passes through (2,4),

which corresponds to the point that was provided for g(x) (4,8),

which is twice as big.

Given that f(x) = x²

then g(x) = 2f(x)

Thus, the function of g(x) = 2x²
