Hey can you please help me posted picture of question
iragen [17]
We have the following function:
 C (t) = 6t - 180
 Clearing t we have:
 6t = c + 180
 t = c / 6 + 180/6
 Rewriting:
 t (c) = (c + 180) / 6
 Answer:
 
The inverse function for this case is given by:
 
t (c) = (c + 180) / 6

RSM QUESTION NEED HELP!!!!!! A pharmacist has a 13 % alcohol solution and another 18 % alcohol solution. How much of each must h
Luden [163]

Answer:

40 grams of 13% alcohol solution and 10 grams of 18% alcohol solution.

Step-by-step explanation:

13%(x) + 18%(50-x) = 14%*50g   Multiply them all

0.13x + (9-0.18x) = 7

0.13x-0.18x + 9 = 7   Simplify the equation and subtract 0.13x from 0.18x

9-0.05x = 7   Add 0.05x to each side

9 = 7+0.05x   Subtract 7 from both sides

0.05x = 2   Multiply each side by 100

5x = 200   Divide both sides by 5

x = 40

50 - 40 = 10

40 grams and 10 grams

Your welcome

Classify the triangle
natka813 [3]

Answer:

This triangle is an isosceles acute

Step-by-step explanation:

First lets define each classification

scalene - no equal sides

isosceles - two equal sides

equilateral - all equal sides

acute - all angles have a measure of less than 90 degrees

right - has a right angle (90 degree angle)

obtuse - has an angle that has a measure of more than 90 degrees

Now lets classify

The triangle has two equal sides (indicated by the little line on the top and bottom side) therefore it is an isosceles triangle

We know its an acute triangle because the one angle given is not a right angle nor a obtuse angle meaning that the other two angles are going to have  a measure of less than 90 degrees

So we can conclude that this is an isosceles acute triangle

PLEASE HELP THIS IS TIMED WILL GIVE BRAINLIEST
Elodia [21]

Answer:Ok, we have:

d(t) = 3*t^2 + 5*t - 2.

The first interval is:

(2, 3)

and remember that, for an interval (a,b), the difference quotient is:

D = (f(b) - f(a))/(b -a)

Then in this first interval we have:

So the average rate of change in (2,3) is 20.

now, in (2, 2.5) we have:

So here the rate of change is 9.25

And in the interval (2, 2.1) we have:

So in this interval the rate of change is 1.73

Step-by-step explanation: hope this helps luvv
