Answer:

2x^4+4x^2+2

Step-by-step explanation:

f(x) = x^2+1

g(x) = 2x^2

g(f(x))=

Replace x in the function g(x) with the function f(x)

=2( x^2+1)^2

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

= 2x^4+4x^2+2

Slope (y2-y1)/(x2-x1)
(0-4)/(-5-5) = -4/-10 = 2/5
Y = 2/5x + b
Plug in any point
4 = 2/5(5) + b
4 = 2 + b, b= 2
Final equation: y = 2/5x + 2

Yo im not good at this stuff, can someone help me?

Kazeer [188]

Answer:

21 kWh

Step-by-step explanation:

1. Subtract 25% from the original amount.

25% of 28 kWh is ...

0.25 × 28 kWh = 7.00 kWh

Subtracting this from 28 kWh, we find the usage after reduction to be ...

28 kWh - 7 kWh = 21 kWh

2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...

(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh

Mario must reduce his usage to 21 kWh or less.

Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y

Monica [59]

Answer:

Step-by-step explanation:

To find the value of y when x = 8 we must first find the relationship between the two variables.

The statement

y varies directly with variable x is written as

y = kx

where k is the constant of proportionality

when

x = 12

y = 3

Substitute the values into the above formula and solve for k

That's

3 = 12k

Divide both sides by 12

$k = \frac{1}{4}$

So the formula for the variation is

$y = \frac{1}{4} x$

when

x = 8

$y = \frac{1}{4} \times 8$

we have the final answer as

Hope this helps you
