Answer:
True
Step-by-step explanation:
For any function of the form the coefficient a produces a reflection of the function whenever .
We can verify it in the following way.
Take, for example, the function:
Now let's make
Now let's in the following function:
We have:
We can see then that the function was reflected in the axis -y by placing a negative coefficient a.
You can see more examples in the attached images
Therefore we can conclude that the statement is true.

×36×120
36 girls can fold 120 paper cranes in minutes = 864864
Hence 36 girls can fold 120 paper cranes in 864 minutes
The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.
<h3>What is an expression?</h3>
An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.
<h3>
Calculation:</h3>
It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as
f(x) = 0.48 ln(x+2) + 27
Here x is the distance in miles from the eye of the hurricane.
f(x) is the pressure of the mercury in a barometer in inches
So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is
(Here f(x) = 28)
f(x) = 0.48 ln(x+2) + 27
⇒ 28 = 0.48 ln(x+2) + 27
⇒ 0.48 ln(x+2) = 28 - 27
⇒ ln (x+2) = 1/0.48
⇒ ln(x+2) = 2.0833
Applying exponential base "e" on both sides, we get
(x+2) =
⇒ x + 2 = 8.0309
⇒ x = 8.0309 - 2 = 6.0309
When the result is rounded to the nearest whole number, we get x = 6 miles.
Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

Answer:
Leah has 15 stickers left.
Step-by-step explanation:
The total number of stickers that Leah had was 50. Leah gave 1/2 of the stickers to her sister. This means that the number of stickers that Leah gave to her sister was: 1/2 × 50 = <u>25 stickers</u>
.
Of the amount left, she gave 2/5 to her brother. This means that the number of stickers that Leah her brother was
: 2/5 × 25 = <u>10 stickers
</u>.
Therefore, the number of stickers that Leah have left for herself is
:
50 - (25 + 15)
= 50 - 35
= <u>15 stickers</u>
I hope this helps you!
Have a great day! :)
