Answer:

100

Step-by-step explanation:

If you add 100 to both sides, you get "x^2-20x+100," which simplifies to (x-10)^2

Find the area of the region under the graph of the function f on the interval
vlada-n [284]

Answer:

9/2

Step-by-step explanation:

this is a simple integral function

given limits of interval [a,b] of a continuous function f(t), you can find the area under the curve by using:

\int\limits^a_b {f(t)} \, dt

\int\limits^3_0 {3x-x^2} \, dx

using the fundamental theorem of calculus that states the integral of f(x) in the interval [a,b] is  = g(a)-g(b), where g(x) is the antiderivative of f(x)

our g(x) = \frac32x^2-\frac13x^3

g(3)-g(0) = g(3) = 27/2 - 27/3 = 27/2-9 = 9/2

7(x+4)−6(x+3)=x+5 what is x
shusha [124]

Answer: No solution

Step-by-step explanation:

7(x+4) - 6(x+3) = x + 5

7x + 28 - 6x - 18 = x + 5     distributing

7x - 6x - x = -28 + 18 +5

0 = -5       <u>Not true</u>

No solution

PLEASE HELP AND SHOW WORK SIMPLIFY THIS RADICAL
Yakvenalex [24]

Answer:

x^2 | y^25 |√187x

Step-by-step explanation:

First you simplify the equation then you factor 184 into its prime factors which is   184 = 23 • 23  

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent. Factors which will be extracted are: 4 = 22 Factors which will remain inside the root are: 46 = 2 • 23 To complete this part of the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by 2: 2 = 2 At the end of this step the partly simplified SQRT looks like this: 2 • sqrt (46x5y50)  Rules for simplifing variables which may be raised to a power: (1) variables with no exponent stay inside the radical (2) variables raised to power 1 or (-1) stay inside the radical (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples: (3.1) sqrt(x8)=x4 (3.2) sqrt(x-6)=x-3 (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples: (4.1) sqrt(x5)=x2•sqrt(x) (4.2) sqrt(x-7)=x-3•sqrt(x-1) Applying these rules to our case we find out that SQRT(x5y50) = x2y25 • SQRT(x) sqrt (184x5y50) = 2 x2y25 • sqrt(46x)

The regular price of a pair of sneakers is $65. They are on sale for 20% off. What is the sale price?
Fofino [41]
65*0.20=13 (0.20 because 20/100=20% is 0.20 in decimal form)
65-13=52
