For all values of x,
f(x) = 2x-3 and g(x) = x²+1
a) Find fg(x)
Simplify and give your answer in the form ax² + b
b) Find gf(x)
Simplify and give your answer in the form ax² + bx+c
Answer:
For f(x) = 2x + 3 and g(x) = -x 2 + 1, find the composite function defined by (f o g)(x)
(f o g)(x) = f(g(x))
= 2 (g(x)) + 3
= 2( -x 2 + 1 ) + 3
= - 2 x 2 + 5 Given f(2) = 3, g(3) = 2, f(3) = 4 and g(2) = 5, evaluate (f o g)(3)

HELP!!!! A quarter circle is attached to the side of a square as shown.
What is the best approximation for the area of this figure?
Use 3.14 to approximate pi.
Answer:
28.56 m²
Step-by-step explanation:
What we need to do for the quarter circle is use the following formula: 1/4(πr²)
(4 * 4) + 1/4(3.14 * 4²)
16 + 1/4(3.14 * 16)
16 + 1/4(50.24)
16 + 12.56
28.56 m²
The best approximation for the area of this figure is 28.56 m².
Answer:
28.6 m2

Answer:
384 square inches
Step-by-step explanation:
The side is 10×5=50
There are 4 sides of equal surface area so we are at 200
The floor is 8×10=80 so we are at 280
The front is 8×5=40 and the back is the same so add another 40 so we are at 360
Add the little triangles which are 4×3=12 and you add the back as well so we get 384 square inches

What is the solution to the system below? x + 5y = 4
x - 5y = -16
(6,-2)
(2,-6)
(-6,2)
(-2,6)
Answer:
(-6,2) third option is correct
Step-by-step explanation:
x+5y=4 equation1
x-5y=-16 equation 2
by adding both equations we got
2x=-12
x=-6
now put x=-6 in any of the equation to get y...
-6+5y=4 equation 1
5y=4+6
5y=10
y=10/5
y=2
(-6,2)
Answer:
(-6, 2)
Step-by-step explanation:
Put (-6, 2) into eq1 and eq2
1. (-6) +5(2)= -6 +10 =4
2.(-6) - 5(2)= -6-10 = -16
only one that works is (-6, 2)

En Cartagena de cada 10 personas 4 tienen una enfermedad, a este ritmo ¿cuántas personas se contagiarán si son 400 personas?
porfa para ya
ayudaaaaaaa
Answer:
Se contagiarian 160 personas.
Step-by-step explanation:
Para este problema debenos usar la siguiente regla de tres:
[tex]\frac{10(personas)}{4(enfermas)}=\frac{400(personas)}{x(enfermas)}[/tex]
Ahora, debemos despejar x de la ecuacion de arriba.
[tex]x=\frac{400(personas)*4(enfermas)}{10(personas)}[/tex]
[tex]x=160(enfermas)[/tex]
Por lo tanto, se contagiarian 160 personas.
Espero te haya sido de ayuda!
