Find g (x) - f (x). <br><br> g (x) = x^2 + 1 and f (x) = 2x + 5

allochka39001 [22]

Answer:

x^2 - 2x - 4

Step-by-step explanation:

g(x) - f(x) = (x^2 + 1) - (2x + 5) = x^2 + 1 - 2x -5 = x^2 -2x +(1-5) = x^2 - 2x - 4

Ryan estimates the measurements of the volume of a container to be 36 cubic inches. the original volume of the popcorn container

PolarNik [594]

Answer:

difference: -4 cubic inches
% change: -10%

Step-by-step explanation:

The difference between the new volume and the original volume is ...

(new volume) - (original volume) = (36 in³) - (40 in³) = -4 in²

The percentage change is figured with respect to the original volume:

% change = (difference)/(original volume) × 100% = (-4 in³)/(40 in³) × 100%

= -1/10 × 100% = -10%

Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.

CaHeK987 [17]

Answer:

Carlos has practiced piano for $\frac{29}{20}=1\frac{9}{20}$ hours.

Carlos needs to practice $\frac{11}{20}$ hours.

Step-by-step explanation:

We have been given that Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.

First of all, we will find piano practiced before school and after school by adding both amounts as:

$\frac{3}{4}+\frac{7}{10}$

Make a common denominator:

$\frac{3*5}{4*5}+\frac{7*2}{10*2}$

$\frac{15}{20}+\frac{14}{20}$

Add numerators:

$\frac{15+14}{20}$

$\frac{29}{20}$

Therefore, Carlos has practiced piano for $\frac{29}{20}$ hours.

Now, we will subtract $\frac{29}{20}$ from 2 find number of hours Carlos needs to practice to reach his goal.

$2-\frac{29}{20}$

$\frac{2*20}{20}-\frac{29}{20}$

$\frac{40}{20}-\frac{29}{20}$

$\frac{40-29}{20}$

$\frac{11}{20}$

Therefore, Carlos needs to practice $\frac{11}{20}$ hours before going to bed in order to meet his goal.
