Answer:

Its 3.5c

Step-by-step explanation:

Let's find the constant of proportionality.

In the proportional relationship between c, the number of cranes, and t, the total time in minutes, one constant of proportionality is the amount of time per crane. It is the number we multiply by the number of cranes to get the total time.

c times ? =t

The constant of proportionality is 3.5 This means we can multiply 3.5 by the number of cranes to get the total time.

Now, let's represent that as an equation.

total time= time per crane X number of cranes

total time

time per crane×number of cranes

3.5c

One correct equation is:

t= 3.5c

Answer:

$3.45\times10$

Step-by-step explanation:

$(2.3 \times 10^{4}) \times ( 1.5 \times10^{-3} )= 2.3\times1.5\times10^{4}\times10^{-3}$

$= 3.45\times 10^{((4)+(-3))}$

$=3.45\times10$

10 of the students in Miss Ransom‘s class play an instrument. These 10 students make up 40% of the class how ,many students are

Mashutka [201]

Answer:

250 students

Step-by-step explanation:

Given data

Let the total number of students be x

Number of students that plays instrument = 10

Hence

40% of x = 10

40/100*x= 100

0.4x=100

x=100/0.4

x= 250

Hence there are 250 students in total

Determine the inverse of the function f (x) = 4(x − 3)2 + 2. inverse of f of x is equal to 3 minus the square root of the quanti

Elodia [21]

The inverse of the function f(x) = 4(x-3)² + 2 is $f^{-1}(x) = \sqrt{\frac{x-2}{4} } + 3$

The given function is:

f(x) = 4(x - 3)² + 2

To find the inverse of the function:

Make x as the subject of the formula

$4(x-3)^2 = f(x) - 2\\(x-3)^2 = \frac{f(x)-2}{4} \\x - 3 = \sqrt{\frac{f(x)-2}{4} } \\x = \sqrt{\frac{f(x)-2}{4} } + 3$

Replace x by $f^{-1}(x)$ and replace f(x) by x

$f^{-1}(x) = \sqrt{\frac{x-2}{4} } + 3$

Therefore, the inverse of the function is:

$f^{-1}(x) = \sqrt{\frac{x-2}{4} } + 3$
