A weather station on the top of a mountain reports that the temperature is currently 0°C and has been folling at a constant rate

alukav5142 [94]

Answer:

Step-by-step explanation:

This question is incomplete; here is the complete question.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.

If it continues to fall at this rate, what will the temperature be:

In 2 hours ............. In 5 hours .............. In half an hour......................

If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.

Then after 'x' hours, temperature on the top of the mountain will be represented by the function,

T(x) = 0 - 3x

Therefore, temperature after 2 hours = -3(2) = -6°C

Temperature after 5 hours = -3(5) = -15°C

Temperature after half an hour = $-3(\frac{1}{2})$

= -1.5°C

Hannah invested $4000 in a savings account that that earned 2% interest compounded quarterly. she determined that if she does no

Svetach [21]

Answer:

Her account balance after 3 years is $4,246.71

Step-by-step explanation:

In this question, we are tasked with calculating what Hannah's account balance will be after 3 years and the error she made in her calculations

Mathematically, to calculate the account balance after 3 years, we use the formula for the compound interest as follows.

Mathematically, the amount A earned on a compound interest is calculated as

A = P $(1+r/n)^{nt}$

where A is the account balance after the number of years which is what we want to know

P is the initial amount invested which is $4000

r is the interest rate which is 2%(2/100 = 0.02) according to the question

n is the number of times interest is compounded per year which is 4(quarterly means every 3 months)

t is the number of years which is 3

We plug the values into the question;

A = 4000(1 + 0.02/4)^(3)(4)

A = 4000(1+0.005)^12

A = 4000(1.005)^12

A = $4,246.71

P.S ; I do not see Hannah's calculation and as such I cannot spot where she made the error in her calculations

Use the data to create a scatter plot.

Naddika [18.5K]

For this case, what you should do is plot each ordered pair as a scatter diagram.
The ordered pairs are:
(5, 8)
(6.5, 12)
(4, 9.5)
(3.5, 5)
(2, 7)
(5, 7.5)
Answer:
See attached image.
There seems to be an increase in weight as time passes.

Earl has 4 more dimes than quarters. if earl has 10 quarters, how many dimes does he have?
