I don’t understand it

kondaur [170]

Answer:

m<F=50

Step-by-step explanation:

complementary angles mean that together they equal 90, we need to set up an equation to find x, and then put x into angle F to find its measurement :)

m<C+m<F=90

(2x+10)+(x+35)=90

calculate to find x!

x=15

now we put 15 into (x+35)

15+35=50

hope this helps!! :D

Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).

stich3 [128]

Answer:

$(g\cdot f) = -3x^2-3$

Step-by-step explanation:

$f(x) = x^2 + 1$

$g(x) = -3$

The problem state to multiply the function $f$ and $g$ so the symbol seems to be incorrect.

We actually want to calculate

$g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3$

Note

$g\circ f(x)=g(f(x))=g(x^2+1)=-3$

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.

tia_tia [17]

Answer:

Alloy = 12.6 lbs.

Step-by-step explanation:

( 2/7 ) = ( Nickel /4.9)

Nickel = 1.4 lbs.

Ratio of Copper to Zinc:

( 9/7 ) = ( Copper /4.9)

Copper = 6.3 lbs.

Alloy = Zinc + Nickel + Copper

Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

Alloy = 12.6 lbs.
