Answer:

2<∛13<3 1<∛6<2

Step-by-step explanation:

Lets find the integers a and b ∛13 lies between.

a<∛13<b

a³<13<b³

=> a=2 so 2³=8 and b=3 so 3³=27 8<13<27

Similarly a<∛6<b

a³<6<b³

a=1 and b=2

The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals

statuscvo [17]

Answer:

The number of additional shots on goal to score 3 more goals is 36

Step-by-step explanation:

Let

x ----> the number of goals scored

y ---> the number of shots on goal

we know that

$\frac{x}{y}=\frac{4}{48}$ ----> equation A

For x=3

substitute the value of x and solve for y

$\frac{3}{y}=\frac{4}{48}$

$y=\frac{48}{4}(3)$

$y=36$

therefore

The number of additional shots on goal to score 3 more goals is 36

Maxim and Salma were asked to find an explicit formula for the sequence 54,63,72,81,... Maxim said the formula is f(n)=54+9n Sal

Sever21 [200]

ANSWER

The explicit rule is

$f(n) = 45+9n$

EXPLANATION

The given sequence is :

54,63,72,81,...

The first term of this sequence is

$a = 54$

The common difference is

$d =63 - 54 = 9$

The explicit rule is given by:

$f(n) = a + d(n - 1)$ $f(n) = 54+9(n -1 )$

We expand to get:

$f(n) = 54+9n -9$

$f(n) = 45+9n$

None of them is correct .
