4. On a math test, Sarah has to identify all the coefficients and constants

Mathematics
1 answer:
nordsb [41]4 years ago
7 0

Answer:

Step-by-step explanation:

4 + n + 7m

constants are just the numbers with no variables (letters)

so the constant is 4

coefficients are numbers multiplied by variables (letters)

so the coefficients are : 7 and 1

the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.

Find the rule for the sequence<br> First term: 2 3/4<br> Sixth term: 3 7/12<br> Rule:_______
Fantom [35]
K, so areitmetic

an=a1+d(n-1)
a1=first term
d=common differnce

we are given
a1=2 and 3/4
6th term is 3 and 7/12

so

a6=3 and 7/12=2 and 3/4+d(6-1)
3 and 7/12=2 and 3/4+d(5)
minus 2 and 3/4 both sides
10/12=5d
divide both sides by 5 or multiply both sides by 1/5
2/12=d
1/6=d


a_n=2 \frac{3}{4}+ \frac{1}{6}(n-1) or
a_n=2 \frac{7}{12}+ \frac{1}{6}n
that is the rule

PLEASE HELP, WILL MARK BRAINLIEST!
Leokris [45]

Answer:

8,5 feet

Step-by-step explanation:

The equation of the form

x² + y² = (r)²

Is the equation of the circumference

We have for the pool:

x²  +  y²  = 2500      ⇒  x²  +  y²  = (50)²

And for the outside edge of the footpath

x²  +  y²  = 3422,25  ⇒  x² + y²  = (58,5)²

So we obtain the radius of each circumference

For the outside edge of the pool  r₁  = 50 feet

For the outside edge of the footpath r₂ = 58,5  feet

Then the width of the footpath is  58,5  - 50  =  8,5 feet
