Answer:
Exponential function is:
y = 100 (1.03)ˣ
Step-by-step explanation:
We know that the exponential growth function is of the form
y = a (1 + r)ˣ
Here:
a = initial value
r = growth rate
x = number of time intervals that have passed
Given that A new savings account is opened with 400. Thus,
a = 400
Given that a new saving account gains 3% every year.
r = 3% = 0.03
now substituting a = 400 and r = 0.03 in the function
y = a (1 + r)ˣ
y = 100 (1 + 0.03)ˣ
y = 100 (1.03)ˣ
Therefore, exponential function is:
y = 100 (1.03)ˣ
Please note that the growth factor i.e. 1.03 is greater than 1, so the exponential function represents exponential growth.

Find the length of an altitude of an equilateral triangle with sides of 4 cm.
Answer:
c.
Step-by-step explanation:
Altitude of Equilateral Triangle h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60° Sides of Equilateral Triangle: a = b = c.
Are the lines parallel? y = x + 4 and y = x - 2 *
1. yes, they have the same slope and a different y-intercept
2. no, they are not parallel
You can text 44 words in 1 minute. Write a proportion to help you find
how many words you can type in 4 minutes. Which choice sets up the
proportion correctly and has the correct solution?
Answer:
176 words
Step-by-step explanation:
1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:
44 words = x
1 minutes = 4 minutes
2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.
3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!
4) multiplying 44 by 4 would get us our answer which is 176
im not the best at math but i this explanation helped <33

Answer:
m∠M = 47°
m∠R = 124°
Step-by-step explanation:
HOME = TRAP
Judging buy the picture there is only one corner that sticks out compared to the rest of the angles. Meaning that A and M are the same because they are the only angles that are easily identical to each other. Then match the letters using this information
m∠A = m∠M
m∠R = m∠O
m∠T = m∠H
m∠P = m∠E
Now all you need to find is m∠R and m∠M
m∠A = m∠M means m∠M = 47° since m∠A is 47°
Same concept goes for m∠R = m∠O.

Part b: The rate the oil fills the tank
Part c: The amount of liquid in the tank to begin with.
Hope this helps. :)
As per the graph that shows the volume of oil in tank T sec.
The gradient of the graph is 2.5The gradient shows rate of oil in the tankThe value represents the amount of liquid in the tank.What eos the do graph tell?The given graph describes the volume of the oil in L and shows the value in t seconds. The gradient of the graph is about 2.5 and it shows us the amount of liquid in the tank. The value of the graph that intersects at the L 2 is the amount of liquid found in the tank.
Find out more information about the graph.

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?
Answer: 0.1056
Step-by-step explanation:
Given: Chipotle Burritos are normal distributed with
Mean = 200 mm
Standard deviation = 8 mm
Let x be the length of a random burrito.
The probability that a burrito picked at random is shorter than 190mm will be :
[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]
Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

Write a rule for the linear function in the table.
f(x) = 4x + 3
f(x) = –4x – 3
f(x) = x + 3
f(x) = [tex]\frac{1}{4}[/tex]x +3
Answer: I would go with A. f(x) = 4x + 3
Nothing further can be done with this topic. Please check the expression entered or try another topic.
f ( x ) = 4 x + 3 , f ( x ) = − 4 x − 3 , f (x ) = x + 3 , f ( x ) = x + 3
Step-by-step explanation: Set up the composite function and evaluate.
f ( 4 x + 3 ) = 16 x + 15
Graph.
f ( x ) = 4 x + 3
f ( x ) = − 4 x − 3
f ( x ) = x + 3
f ( x ) = x + 3
