(f•g)=   f(1)•g(1)

= 5(1)^2 • (1)+1

= 5(1) • 2

= 5 • 2

= 10

Your answer here is 10.

Hope I helped!

If function F is defined by f(x) = 3x^2 + 5, what is f(x-4)
shepuryov [24]

Answer:

The function f(x) when x=x-4 is f(x-4)=3x^2-24x+53  or f(x-4)=3x(x-8)+53

Step-by-step explanation:

Given function f is defined by f(x)=3x^2+5

Now to find the function f(x-4):

f(x)=3x^2+5

Put x=x-4 in the above function we get

f(x-4)=3(x-4)^2+5

f(x-4)=3(x^2-2(x)(4)+4^2)+5 (using the formula (a-b)^2=a^2-2ab+b^2)

f(x-4)=3(x^2-8x+16)+5

f(x-4)=3x^2-24x+48+5 (adding the like terms)

f(x-4)=3x^2-24x+53

f(x-4)=3x(x-8)+53

Therefore f(x-4)=3x^2-24x+53  or f(x-4)=3x(x-8)+53

The function f(x) when x=x-4 is f(x-4)=3x^2-24x+53  or f(x-4)=3x(x-8)+53

Tom jogged 3/5 on Monday and 2/6 mile on Tuesday. How much farther did Tom jog on Monday than on Tuesday
natali 33 [55]
You will want to subtract the amount he ran on Monday from the amount on Tuesday. In order to subtract fractions, we must set them to the same denominator (bottom number). In order to do this, we must multiply 3/5 by 6/6 (the denominator on tuesday) which gets us 18/30. Then, for Tuesday, we must multiply 2/6 by 5/5 (the denominator on Monday) which is 10/30. Now, we can do Monday-Tuesday, 18/30-10/30 which gets us 8/30, if we simplify this, we get 4/15 :)

PLS HELP ASAP THANKS ILL GIVE BRAINLKEST PLS THANKS PLS ASAP
abruzzese [7]

Answer:

(-7, 8)

step-by-step explanation:

  • original coordinates of B: (-9, -8)

if translated two units horizontally, there will be change in x axis

  • new coordinates: (-9+2, -8) → (-7,-8)

if reflected over x-axis, use the formula: (x,y) → (x, -y)

  • new coordinates: (-7, -(-8)) → (-7, 8)
