Alright, first let's make a variable for the number.
'n'
Pretty easy right?
Now, we know that the equation contains the sum of n and 3.
n + 3
Since 35 is 9 more than the sum of n and 3:
(n + 3) + 9 = 35
Great! Now we have the equation!
We can open the parentheses and add 9 and 3
n + 12 = 35
Subtract both sides by 12:
n = 23
The unknown number is 23!

for a short time after a wave is created by wind the height of the wave can be modeled using y= a sin 2pit/T where a is the ampl
dangina [55]

Answer:

y = 4 sin(t/2 + 4π/3) − 2

Step-by-step explanation:

General form:

y = a sin(2π/T t)

Given a = 4 and T = 4π:

y = 4 sin(2π/(4π) t)

y = 4 sin(t/2)

Add horizontal shift of -4π/3 and vertical shift of -2:

y = 4 sin(t/2 − (-4π/3)) − 2

y = 4 sin(t/2 + 4π/3) − 2

Sarah hopes to be 5 feet tall by her next birthday. Right now, she is 148 centimeters tall. About how many more centimeters does
Alla [95]

Answer:

4.4 cm

Step-by-step explanation:

To solve this problem, we have to remind the conversion factor between feet and cm. We know that:

1 foot = 12 inches

1 inches = 2.54 cm

So,

1 ft = 12 \cdot 2.54 =30.48 cm

In this problem, Sarah's height right now is

h = 148 cm

She wants to be 5 feet tall by her next birthday: it means that her height should be

h'=5 ft \cdot 30.48 =152.4 cm

Therefore, she needs to grow by:

h'-h=152.4-148=4.4 cm

So, she needs to grow 4.4 cm more in order to be 5 feet tall.
